Introduction

Now a day, goat farming has become more commercial. Due to its good economic prospects, goat rearing under intensive and semi-intensive system for commercial production has been gaining momentum for the doubling the income of the farmers. There is good encouragement from governments with providing subsidies on especially stall fed goat farming. Goat is being raised for centuries as poor man’s cow due to its importance of providing employment in rural areas by producing healthy meat. Goats also play major role in agriculture economy of India. Goat is excellent source of additional income for poor and landless owners. The goat milk is nutritious and easily digestible milk to their kids. Goats are easy to maintain as they can graze on open land. Goat farming is an excellent option where fodder and forage is limited. Goat farmers can get good returns with successful goat rearing. Goats are among the main meat producing animal in India, whose meat (chevon) is one of the choicest meats and has huge domestic demand. High demand of goat and its products with potential of good economic returns have been deriving many progressive farmers, business, professionals, ex-servicemen and educated youths to take up the goat enterprise on a commercial scale. The emerging favorable market conditions and easy accessibility to improved goat technologies are also catching the attention of entrepreneurs.

Sheeps were first domesticated by human being, many thousands of years ago for their wool, meat and skins. It provides a source of income to the shepherds through sale of wool and animal. Sheep do not need expensive building to house them and require less labour than other kinds of livestock. Sheep are economical convertor of grass into meat and wool. Sheep will eat varied kinds of plants compared to other kind of livestock. This makes them excellent weed destroyer. Unlike goats; sheep hardly damage any tree. The production of wool, meat and manure provides three different source of income to the shepherd. The structure of their lips helps them to clean grains lost at harvest time and thus convert waste feed into profitable products.

Abstract

Potato in India was introduced as a long day temperate crop which found suitable climate in the higher hills of the country. Since then it is grown widely in the Indo-Gangetic Plains, the Plateau and the Himalayan regions in north and the Nilgiris hills in south of India. The Central Potato Research Institute (CPRI), Shimla has developed 49 potato varieties by the conventional breeding for suitable cultivation of potato in different potato zones of India. A number of technologies for ware- and quality seed- potato production, storage and processing have been developed/standardized for adoption by the end users. These technologies have contributed immensely towards multiple increase in area, production and productivity of potato during last sixty years. Apart from conventional tools, modern biotechnological tools like whole genome sequencing technology, transgenics technology, molecular markers, RNAi and microarray technology have are also being employed in potato improvement.

INTRODUCTION
 
In India tremendous progress has been made in agriculture. In absence of check on population growth, it may cross 1.5 billions by 2030. As a consequence per capita availability of land 0.13 ha will further reduce to 0.1 hectare in 2020 A.D. The demand of growing population for food and fibre require country to produce higher yields from presently cultivated land. Currently an average of 2790 calories of food available each day for every human on the planet, (23 per cent more than in 1961 and enough to feed every one). The production targets and required yield to feed the ever increasing current population with present available resources will require the growth rate of 2.35 and 2.2 per cent in rice and wheat, respectively and as high as 4.45 and 3.38 per cent for pulses and oil seeds, respectively. This requires national average yield to be increased by 30-50 per cent, which is not a cakewalk. India will require producing additional 5-6 million tones annually to keep pace with ever-increasing national food and nutritional requirements. Recurrent famines, starvation death and lack of resources led to green revolution, which as of now has turned our begging bowl to agriculturally advanced cereal exporting country.

Advancements on sugar processing

India has popped out as one of the largest sugar processing country throughout the world. Through the collaboration of research and development carried out in the field of sugar processing, this industry has witnessed the vast changes in term of technology. Important considerations such as productivity improvement and cost reduction were the main objectives in the field of sugar processing. Sulphur dioxide was earlier used but afterwards lime treatment in clarified juice helped in the processing of white sugar from sugar cane. Since then the continuous progress and improvement has been made and advanced techniques are introduced for manufacturing of sugar with modern tools.

Ramjeawon (2004) reported that farmers and agriculture workers grow sugar cane and beet root for sugar production,providing about 20 kg per capita and that is equivalent to almost 13 percent energy requirement. Fechter et al. (2001) reported that production of the white sugar was focused more on juices rather than molasses which were taken as the raw material. Various processes such as ultra-filtration, de-mineralization and de-colorization were used for the production of white sugar. The traditional refining process wascheaper, and effective in terms of purification and juice purification was the method used for the processing of white sugar directly from the sugar cane. Crystallization was one of the process which is used for increasing the recovery of sucrose and it reduces the molasses production. Chromatography was used in the sugar industry for the separation of sucrose. Another method was ion exchange demineralization which was used in the sugar industry for the removal of minerals from the liquid sugar. Later adsorption has been incorporated to be used de-odorization and de-pigmentation. Membrane filtration is latest technique used in the process which was used for maintaining the quality of white sugar by removing unwanted particle from the juice. Velásquez et al.,(2018) reported that thermal processes are also used for the production of sugar from sugar cane. Non centrifugal cane sugar processing is used for this purpose and the product is obtained by evaporating the sugarcane which has the unique flavor and aroma. Later the product is used as the sweetener and has a traditional characteristics flavor and optimum nutrition.

Introduction 
A broad definition of bioprocessing is the process of creating a valuable product from a live source. The system’s most important element is that the source organism is living and sensitive to its surroundings. Accordingly, the framework states that it will respond to relatively small changes in its physico-chemical environment by modifying its physiology to maximise efficiency. The use of entire cells and enzymes to catalyse bioprocesses in industrial settings is becoming more popular these days than conventional chemical synthetic methods. Among the many benefits of biotransformations in this context are their extensive substrate portfolio (including liquid, solid, and gas waste), one-pot reactions in mild circumstances and environmental friendliness. However, a number of drawbacks, including the unstable nature of biocatalysts and subpar performance in specific reaction conditions, the low solubility of some substrates in the reaction medium, substantial production expenses brought on by intricate downstream processing and product isolation and the lack of expertise in microbiology or bioprocess design, frequently make it difficult to scale up bioprocesses from the lab to the manufacturing facility. There is a growing need for innovative bioprocesses that can get over the aforementioned obstacle in industrial and environmental biotechnology in order to create effective, sustainable, and affordable processes. As a result, the industrial sector requires new methods that use biocatalysts that are highly active and stable under a variety of reaction conditions (typically accomplished through metabolic engineering), boost feedstock utilisation by using inexpensive waste resources, use green chemistry solutions that enable the use of fewer toxic solvents and reagents, or develop cost-effective biorefinery concepts that can transform industrial waste and byproducts into products with added value, thereby establishing new value chains. Figure 1.1 shows the three stages of a typical bioprocess: upstream processing, bioreaction and downstream processing which includes separation and purification steps. Every stage of these phases offers multiple chances to enhance a certain bioprocess.

Preamble

The recent advances in embryo transfer protocols have placed these techniques as widely adopted means of developing experimental models to understand complex biological processes such as feto-maternal dialogue, fetal programming and maternal effects on early development. This has noticeably widened the scope of embryo transfer programs which are now not only limited to transferring the genetically superior embryos from donors to recipients for faster genetic improvement, or as only the therapeutic tools in human medicine, but has embarked these techniques as basic research tools in biological research. It is however critical to achieve effective synchronization between donors and recipients along with optimal superovulation in donors to get more number of transferable embryos and subsequently greater conception rates of recipients. For transfer, the embryos are collected Day 6 or 7 post insemination of donors. An overall discussion of sequential steps to achieve successful embryo transfer along with recent advances in the subject area and its possible future scope is discussed in this chapter.

Abstract

The extensive use of antibiotics has raised serious health concern throughout the world due to development of resistance in microbes towards many classes of antibiotics. The emergence of multidrug resistance (MDR) in microbes and lack of novel classes of antimicrobial agents have raised an immediate need to identify new agents with novel mode of action. In addition to novel agents, inhibitors of efflux pumps are being now viewed as one of the most viable management strategy for treating MDR infections. In this concern, plants have always been a source of inspiration for novel drugs.

Introduction
The safety of meat and its derivatives is a paramount concern in the dynamic realm of food trade. Consumers demand food products that are not only affordable and possess an extended shelf life but are also of high safety standards. Consequently, meat inspections require strict adherence to good manufacturing practices and safety labelling that aligns with regulatory standards. Food-borne pathogens, including Listeria monocytogenes, Staphylococcus aureus, pathogenic Escherichia coli, Clostridium perfringens, Campylobacter spp., and Vibrio spp., are responsible for numerous illnesses, thereby exerting a significant impact on public health and the economy. According to the World Health Organization (WHO), food contaminated with pathogens, chemicals, and allergens results in 600 million cases of food-borne illnesses and approximately 400,000 deaths globally each year. Furthermore, 56 million individuals die annually, with about 7.7% of the global population affected by foodborne diseases. Meat and meat products are essential sources of nutrients for humans, providing high-quality protein, essential amino acids, B vitamins, and minerals. However, due to their high-water activity and nutrient content, they also create a conducive environment for spoilage microorganisms and food-borne pathogens. Until a few decades ago, the meat industry was largely dominated by the unorganized sector, with limited access to knowledge that could enhance productivity. However, in the post-World Trade Organization (WTO) era, meat entrepreneurs have succeeded in increasing productivity, although they have faced challenges in ensuring product quality that aligns with the legislative standards of numerous developed and developing countries. The use of antibiotics as antimicrobial growth promoters in animal food production has been a contentious issue, as their unauthorized application has inadvertently contributed to the emergence of antibiotic-resistant bacteria within the food chain. Recently, the United States Trade Representative’s office estimated that international trade has expanded significantly since the General Agreement on Tariffs and Trade (GATT) was signed in 1947. The establishment of the WTO in 1995 further facilitated trade in animal-origin foods and live animals between nations. However, the emergence and re-emergence of diseases caused by pathogenic bacteria have become a significant concern in this new pattern of food trade. Some of these pathogens are so virulent that they were not previously reported. According to a 1998 report by the Centers for Disease Control and Prevention (CDC), the annual cost of foodborne illnesses in the United States is nearly 10 billion US dollars. The bacterial pathogens most commonly associated with illnesses from beef products include Salmonella spp., Clostridium perfringens, and Staphylococcus aureus. Interest in Escherichia coli O157: H7 increased following a highly publicized food poisoning outbreak linked to undercooked beef patties in the United States in 1993, although it was largely confined to North America until the mid-1990s. Similarly, multidrug-resistant Salmonella typhimurium DT-104 has spread widely since it was first identified in the United Kingdom. In India, the incidence of Salmonella in red meat was recorded at up to 9%. These potentially harmful bacterial pathogens can reside on the hides or in the intestinal tracts of foodproducing animals or may originate indirectly through cross-contamination or the processing environment. Other emerging foodborne diseases include Listeriosis, which has spread throughout France and Canada, where meat and meat products have been implicated as sources of Listeria monocytogenes. Similarly, Staphylococcal food poisoning or food intoxication syndrome, first reported in 1894, has become a global issue in the meat industry.

Microbes present in the biofertilizer formulations help in microbial processes in the soil which augment the availability of nutrients to be taken up by plants. They are of different types based on their nature and function such as nitrogen fixing, phosphate solubilizing, phosphate mobilizing or biofertilizers for micronutrients. Plants use different strategies for growth promotion at different stages of plant growth and development. Biofertilizers are mass multiplied cultures of specific beneficial microbial strains which improves the fertility of soil and productivity. The nutrients are added through natural processes of nitrogen fixation, solubilization of phosphorus and synthesis of growth promoting substances to stimulate the plant growth. The main sources of biofertilizers are bacteria, fungi and cyanobacteria.

11.1. Bio-enrichment of chemical fertilizers- A new approach

Yield response of different host plant depends on the mineral fertilizer and its fertilizer use efficiency. Generally, such fertilizers are low in efficiency due to environmental and soil factors. A large portion of synthetic fertilizers are lost due to fixation, leaching, run-off, erosion, volatilization, denitrification and precipitation without reaching plants. Hence, there is an economic loss and water and environmental pollution.

Microbial inoculants applied to the soil enhances the uptake of nutrient by plants and increase the efficiency of synthetic or organic fertilizers. In this context, it is possible to impregnate mineral fertilizers with specific microbial strain. A new approach is to incorporate the microbes or microbial compositions into fertilizer compositions.

Introduction
Metal-catalyzed C–N cross-coupling reactions are powerful synthetic methods for producing both simple and complex organic compounds, including natural products. These methodologies typically involve shorter reaction times and can achieve good to excellent yields with a broad range of reactions, exhibiting high regioselectivity in certain cases. The coupling of carbon and nitrogen to create organic compounds that contain nitrogen, such as urea and amides, is one of the most fundamental chemical reactions and plays a crucial role in human civilization. C–N coupling reactions have significant importance in industry, starting with the production of ammonia (NH3) through the Haber–Bosch process. Molecules containing C–N bonds are prevalent in a variety of organic materials, natural products, pharmaceutical compounds, and agricultural chemicals. This wide applicability makes them crucial chemicals, leading synthetic organic chemists to continuously seek out novel synthetic methods. In recent years, numerous synthetic strategies involving either transition metals or metal-free enzymes and biocatalysts have emerged. Additionally, new technologies, such as electroreduction, have been employed in these C–N coupling processes (Bariwal & Van der Eycken, 2013, Li et al., 2022, Yin et al., 2024, Rahman et al., 2022).
Common copper salts/complexes, and diamino ligands
Copper is commonly found coordinated by two, three, or four ligands, resulting in linear, trigonal planar, or tetrahedral geometries. Well-known and inexpensive copper halides, such as copper (II) glycinate, copper (II) acetylacetonate (particularly CuI), copper acetates, copper oxide, copper sulfate, and copper triflate salts, are widely used as catalytic systems in C–N bond-forming reactions. Additionally, other complexes such as Cu di-isopropyl salicylate (CuDIPS), copper phthalocyanine, and copper aspirinates have also been employed in these reactions. Copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions are well-established methods for forming triazoles via C–N bonds in one pot. These reactions often involve domino click chemistry and green approach methodologies, leading to the synthesis of biologically important triazoles. Copper salts in combination with diamine ligands are widely used in C–N bond-forming reactions through cross-coupling strategies. Some notable examples of such diamino compounds that can coordinate with copper are illustrated in Figure 1.

Introduction
In the realm of modern agriculture and plant breeding, the integration of advanced biotechnological tools has revolutionized the traditional methods of crop improvement. Traditional approaches to genetically improving horticultural crops that are primarily propagated asexually encounter multiple challenges. These include an extended juvenile phase, the absence of seeds, a high level of intraand interspecific incompatibility, frequent heterozygosity, seed sterility, and, most importantly, the restriction of certain valuable traits to wild species (Mehlenbacher, 1995). Conventional or classical breeding techniques rely on natural processes and traditional tools to develop new plant varieties or cultivars. However, these methods are often time-consuming, labor-intensive, and less efficient. The lengthy process, coupled with the challenges of maintaining desirable traits, makes it difficult to achieve rapid genetic improvements. As a result, there is a growing need for more advanced and precise breeding methods to enhance crop development (Jain and Kharkwal, 2004). A molecular marker is a specific DNA segment that signifies genetic variations at the genome level, aiding in genetic analysis and breeding (Dhutmal et al., 2018). These are composed of nucleic acids as well as proteins and used on basis of naturally occurring polymorphism (Thottappilly et al., 2000; Ahmad et al., 2020). These markers are closely related with the target gene and they act as sign or flags (Nadeem et al., 2018), aiding in the identification of specific regions associated with advantageous characteristics such as disease resistance, yield potential, nutritional content, and environmental adaptability (Meena et al., 2023).The advancement of high-throughput molecular markers and genetic maps has enabled the precise identification of genes responsible for agronomically important traits, potentially enhancing breeding through markerassisted selection (MAS). Compared to traditional breeding methods, MAS overcomes the challenges of phenotypic selection and significantly improves selection efficiency. This approach accelerates crop improvement by ensuring the effective transfer of desirable traits with greater accuracy and reliability (Wani et al., 2022). The incorporation of next-generation sequencing (NGS) technologies and high-throughput genotyping platforms has also facilitated genome-wide association studies (GWAS) and the discovery of single nucleotide polymorphisms (SNPs) linked to important traits, further enhancing the resolution of genetic analysis. In recent years, molecular markers have been extensively used to characterize and enhance genotypic and phenotypic traits in temperate fruit and nut crops. Studies have focused on assessing genetic diversity in almonds, identifying genes responsible for red skin color in apples, developing sharka disease-resistant apricots, and sequencing the almond genome. These markers have been successfully used for genetic studies in many horticultural crops including vegetables (Gulsen et al., 2007; Kumar et al., 2008 a and b; Schafleitner et al., 2013; Yadav et al., 2015; Sharma et al., 2016; Kumar et al., 2017 and Kumar et al., 2019) and flowering crops (Kumar et al., 2019; Kumar et al., 2016 and Kumar et al., 2018a and b). These advancements highlight the crucial role of molecular markers in improving breeding strategies, accelerating genetic improvements

1. INTRODUCTION

Preservation of foods by drying is perhaps the oldest method known to mankind. Drying is a thermo-physical action and its principles are governed by heat and mass transfer laws inside and outside the product. The weight of the product is reduced to the extent of 1/4^th to 1/9^th of its original fresh weight. Drying of foods and biological products is a widely applied process for different purposes such as increasing the shelf-life, reducing packaging costs, lowering shipping wastes, encapsulating flavours, making food available during off-season, adding value by changing the phase structure of the native material and maintaining nutritional value. Drying or dehydration of fruits and vegetables can be accomplished with low capital while maintaining high quality and obtaining less perishable food products.

Introduction

Supplementary feeding is an essential practice in fish farming operation which accounts for over 60% in total input cost. The dependence of candidate species on balanced supplementary feed increases with increase in stocking population in ponds targeting per hectare higher production as the standing crop of cultured species exceeds the natural feeding capacity of ponds. Therefore, feeding of artificial feed balanced in all nutrients such as protein, lipid, carbohydrate, vitamins and minerals containing optimum protein and energy ratio has assumed foremost importance in aquaculture industry. The use of balanced feed however, is directed towards optimum realization of genetic potentials of farmed species for survival, immunity, growth and reproduction (Mohanty, 2009). Consequent to researches done in India and abroad, a strong data base has been developed about the nutritional behavior of great majority of these cultivable fish and shell fish species and several feed formulations have been successfully undertaken. With optimum pond management, feeding of formulated balanced feed, it has been possible to increase aquaculture production as high as 15- 17 t/ha/yr for carps and 8-12 t/ha/yr in semi intensive prawn and shrimp farming in India (Mohanty, 2009).

Abstract

Vegetables are health capsules, being the chief source of vitamins and minerals besides providing other dietary elements like carbohydrates, proteins and even fat and enzymes to some extent, antioxidants and fibre. Though India is the second largest vegetable producer (147 million tones in 2012) in the world, per capita supply and consumption of vegetables in India is very low (160 g day ^-1). It is now realized that the problems of satisfying hunger and nutrition are much beyond the realm of food crops alone and therefore, to supplement and balance our diet, more vegetables are to be included. Vegetables not only provide nutritional security in rural areas but also financial security to small and marginal land holders growing vegetables in the hinterlands of urban markets. Commercialization of vegetable production is the scene of the day as they are money spinners in domestic markets and dollar earners in global markets. To compete in the domestic and global market and for year round supply of quality produce, protected or greenhouse cultivation of vegetables is imperative. Water and nutrients are the top most growth and production inputs in any crop cultivation and vegetables are no exception to this. In order to get the potential yields with matching quality of vegetables grown under protected cultivation, the best of the management strategies to supply water and nutrients is needed. In this direction, drip fertigation is the best option for efficient supply of irrigation water and fertilizer nutrients for greenhouse grown vegetable crops. The studies carried in different parts of the world have clearly indicated that fertigation technology resulted in substantial yield increase with marked enhancement of water and nutrient productivity.

1. Introduction
With commercial uses ranging from the production of high-quality substances to the manufacture of pharmaceuticals, hydrogenation is an essential step in the formation of organic compounds (Cerveny et al., 1986). There are two main approaches to hydrogenation: direct hydrogenation, which employs pressurized hydrogen gas, and transfer hydrogenation (TH). A versatile and effective approach for producing a large variety of hydrogenated molecules, the TH method entails adding H2 to molecules via an origin other than H2 gas. This approach is increasingly preferred over direct hydrogenation and has recently attracted considerable interest in hydrogenation research. The benefits of the TH method include (i) the elimination of potentially dangerous pressurized hydrogen gas and the complexity of experimental setups, (ii) the accessibility, cost-effectiveness, and ease of use of hydrogen donors, (iii) the potential to recycle the main byproduct, and (iv) the availability and stability of the catalysts employed (Brieger et al., 1974).
1.1. The Historical Context, Core Principles, and Groundbreaking Research on TH (transfer hydrogenation)
With a history spanning more than a century, the TH reaction has a rich past. In order to enable hydrogen transfer between equivalent donor and acceptor units, Knoevenagel showed in 1903 that palladium black could efficiently aid in the disproportionation of dimethyl 1,4-dihydro terephthalate into dimethyl terephthalate and cis-hexahydroterephthalate. Three primary types of hydrogen transfer reactions were distinguished by Braude and Linstead: (i) the hydrogen movement within a single molecule; (ii) hydrogen disproportionation, which entails transfer among identical donor and acceptor units; and (iii) TH-dehydrogenation, which takes place between distinct donor and acceptor units. Of them, THdehydrogenation— often just called TH—is the most well-known and often applied sector. Meerwein-Ponndorf-Verley (MPV) reductions, early transition metal-catalyzed reactions, organocatalytic processes, enzyme-catalyzed reactions, heat techniques, and base-catalyzed reactions are among the types of TH reactions that are classified according to the type of catalyst used. The historical context, important research, and underlying ideas of each category will be covered in detail in this section.In 1925, Meerwein et al. independently reported the significant MPV reduction, which were the first TH process involving carbonyl groups. After earning his Ph.D. under Richard Anschütz in Bonn, where he was appointed a professor in 1914, Hans Meerwein (1879–1965) moved to Königsberg in 1922 and then to Marburg. His name is associated with a number of processes and reagents,

Introduction

In India, climatic conditions are very diverse and fruit crops of temperate, sub-tropical and tropical regions are grown. Frequently, the fruit crops of one regional environmental requirement are grown in another region. This type of crop husbandry has some typical pest problems as the insect and mite pests have easy access to any of these regions depending upon the fruit crop. The application of management approaches in isolation of insect pests on fruit crops demand a unified strategy to suppress the different pest populations under the concept of ‘crop management’. Thus, to sustain the crop management for the better fruit quality, a judicious integration of safe chemical/biopesticide molecules must be used with other non-chemical approaches namely host plant resistance, bioagents, cultural and mechanical practices etc.

Poultry production in India has emerged as a rapid growing sector among agricultural and livestock sector. Indian poultry industry has made a significant impact in economic, nutritional and socio-cultural aspects including livelihoods of poor rural households. Ever since its inception and is presently emerging as sun rise sector with a growth rate of 10-15% and overall turnover of Rs 70,000/- crore. Despite of frequent ingress with various pathogenic avian diseases including avian influenza, which is a severe setback for the industry, India has sustained globally as 3rd and 5th biggest country for egg and meat production respectively. Emerging and re-emerging poultry diseases in the country are posing significant challenges to the poultry industry.

Introduction

The importance of soil in agriculture cannot be overstated, as it serves as the foundation for crop growth and sustenance. However, many regions grapple with problematic soils characterised by issues such as poor fertility, erosion, contamination, and structural degradation. In recent years, significant steps have been made in addressing these challenges through innovative approaches and technologies. This change in outlook includes the combination of imaginative advancements, protection procedures, and biological standards to enhance farming efficiency while limiting ecological effects (Singh et al., 2011).

Farmers are challenged with the management of problematic soils characterised by fertility issues, erosion, contamination, and structural degradation. Sustainable agricultural techniques depend on the efficient management of problematic soils, which is also critical to environmental sustainability, global food security, and farming systems' ability to withstand climate change. The idea of changing soil and harvest management practices a complex system that incorporates accurate horticulture, agroecology, and computerised cultivating innovations (Fu et al., 2021).

Introduction
Because of their useful uses, porous substances are of scientific interest. Depending on the size of the pores, these solids are categorized as microporous, mesoporous, and macroporous. Microporous solids are defined as having pores that are 2 nm or smaller (Figure 1) (Zheng et al., 2002). Solids that are mesoporous fall between 2 and 50 nm, while those that are macroporous are larger than 50 nm (Zheng et al., 2002).
Over the past 20 years, the synthesis of MOFs has garnered a lot of attention since it may produce a wide range of visually pleasing structures that may also be very useful for applications in other porous material-related domains. Coordination polymers, or MOFs (Figure 2), are a type of crystalline materials that are currently garnering a lot of attention because of their appealing qualities. Metal ions serve as connectors and organic bridging ligands as linkers, forming the compound’s backbone. The ligand’s chemical structure and the connecting metals’ characteristics determine whether MOFs will develop the appropriate architectural, chemical, and physical characteristics (Hu et al., 2004). They are permeable and can form structures in one, two, or three dimensions. Because of their intriguing topologies and potential uses as functional materials for gas purification, gas separation, gas storage, and adsorption (Sculley et al., 2011; Friscic, 2012; Lu et al., 2011; Burnett et al., 2012; Lin et al., 2009), molecular magnets (Kang et al., 2012; Zhang et al., 2012; He et al., 2013; Dang et al., 2010; Feng et al., 2012; Ranocchiari et al., 2011; Sumida et al.,2012), heterogeneous catalysis (Sonnauer et al.,2009; Kreno et al.,2012), luminescence, catalysts, and sensors (Chughtai et al.,2015), MOFs and coordination polymers (CPs) are of great interest to modern inorganic chemistry for their logical designation and synthesis. The potential of metal-organic frameworks as appropriate candidates for the detection of a number of pertinent organic and inorganic analytes, such as biomolecules, ionic species, hazardous compounds, environmental contaminants, etc., has been encouragingly realized. MOFs are among the leaders in the development of materials for realtime sensing applications because of their practical ability to tap various types of photophysical processes, even when they are present simultaneously, as well as their freedom to adjust their electronic characteristics and pore surfaces for

Introduction

In horticulture crops, plant materials has been  propagated through vegetative propagation methods for its superiority in growth as well as yield for centuries. Among vegetative propagation methods, micropropagation is most advance technique which made a significance in the horticultural crops to increase quality and yield. It can produce many plants from a single individual.

Abstract

Packaging plays an important role in the food processing Industry. It makes food more convenient as well as gives the food greater safety assurance from microorganisms, biological and chemical changes such that the packed foods can have longer shelf life. In order to meet the huge demand of processed food with longer shelf life, various methods of preservation and packaging are being used in the food processing industry. Drying and dehydration is one of the method which helps preservation of a perishable commodity against deterioration or spoilage.

1. Introduction
Palladium (Pd), which has the atomic number 46, was discovered in 1803 by the English chemist William Hyde Wollaston. It is a well-known transition metal recognized for its versatile catalytic properties in chemical reactions, material sciences, and various industries. The palladium-catalyzed coupling reactions extend beyond the formation of biaryls. Many carbon–carbon, carbon–nitrogen, and carbon–oxygen bond-forming reactions in organic chemistry are facilitated by palladium salts and catalytic systems derived from palladium. Some notable organic reactions that involve palladium include the Mizoroki-Heck reaction, (Biffis et al., 2018, Koranne et al., 2023, Lee et al., 2021) Suzuki-Miyaura coupling, (Zhang et al., 2023) Negishi reaction, (Haas et al., 2016). Stille coupling, (Cordovilla et al., 2015). Sonogashira coupling, (Chinchilla & Najera, 2007) Tsuji-Trost reactions, (Kvasovs et al., 2023). and Wacker catalytic processes. (Zhang et al., 2023) In this chapter, we will focus on the applications of palladium and its salts in C-N bond-forming reactions.
2. Palladium (Pd)-Catalyzed C–N Bond Formation
Besides copper, palladium metal is considered as the most widely used metal in organic synthesis. The discovery of cross-coupling reactions catalyzed by palladium(0) complexes in the 1970s was a highly important achievement that substantially changed the strategy of organic chemistry. Best applications of the palladium salts are in enantiolective and new C-N bond forming reactions. Stephen L. Buchwald and John F. Hartwig opened up the catalytic scope of palladium in newer methodologies on C–N bond forming reactions during 1990s, (Ruiz- Castillo & Buchwald, 2016) and henceforth, new methodologies of carbocycles, heterocycles, and simple organic compounds have been created in large scales (Rayadurgam et al., 2021). The mechanisms of palladium-catalyzed C-N cross-coupling reactions are critically discussed in numerous high-quality research journals with different theoretical and experimentally proven methods (Beletskaya & Averin, 2021). However, the most acceptable mechanistic pathway to reaction products in these Pd-catalyzed reactions involving palladium is illustrated in Scheme 1. The process begins with the formation of a palladium complex through the reaction of an aryl halide (which can be aliphatic, heteroaryl, or functionalized alkenes/alkynes), a palladium salt, and amino nucleophiles. In the presence of a suitable base, the loosely bonded halide or any leaving groups are eliminated, leading to the formation of a palladium (IV) complex. This complex then undergoes reductive elimination, resulting in stable aminated aryl, heteroaryl, alkyl, or functionalized alkenes/ alkynes. Additionally, a more generalized reaction mechanism is presented in a circular pathway format, highlighting the bonding approaches, rearrangements, intermediate formations, and the final release of target compounds, as depicted in Scheme 1. The involvement of higher valence organo-palladium complexes in such catalytic transformations have been well established (Hickman & Sanford, 2012).

The pineapple, botanically known as Ananas comosus Merr, is the most famous edible member of the Bromeliaceae family. It is native to southern Brazil and is known by a variety of names, including “pina” in Spanish, “abacaxi” in Portuguese, “ananas” in Dutch and French, “nanas” in Southern Asia and the East Indies, “po-lo-mah” in China, “sweet pine” in Jamaica, and merely “pine” in Guatemala (Morton, 1987). After banana and mango, the pineapple is the third most important tropical fruit of the world (Chen et al., 2019; Nath et al., 2019). The pineapple became a major cultural icon of luxury after its introduction to Europe in 17th century. Pineapple has been grown commercially in greenhouses and on many tropical plantations since the 1820s. Furthermore, it is the world’s third-largest tropical fruit producer. Hawaii was a major pineapple producer in the twentieth century, with Costa Rica, Brazil, and the Philippines accounting for nearly a third of global pineapple production. Pineapples grow as a small shrub, with the un-pollinated plant’s individual f lowers fusing to form multiple fruits. The plant is usually propagated from a side shoot or an offset produced at the top of the fruit and it matures in about a year.

Crop Improvement

Pineapple is usually propagated through asexual method by using slips, crowns or suckers. Sexual reproduction in pineapple is barely used due to its self-sterile nature and failure in formation of seeds. Seed set can occur in case of self-fertilization but the seedlings are with low vigour due to inbreeding depression (Robert et al., 2003). Pineapple is heterozygous in nature, on this wise hybridization is possible in this crop. Gametophytic self incompatibility is reported in this crop where pollen tube growth is repressed in the uppermost part of the style. Diploid chromosome number of the crop is 2n=50. The genome size of the crop is estimated to be 526Mb and total genes were anticipated to be around 25,862 in number (Zhang et al., 2014).

ABSTRACT

Plant growth promoting (PGP) bacteria play an immense role in promoting crop growth mainly by direct mechanisms such as N_2-fixation, phosphate solubilization and phytohormone production and indirectly may help to suppress pathogens or contribute to enhance absorption of nutrients leading to increase yields. The N₂fixers are grouped based on their niche adaptation as endophytic nodular symbionts (Rhizobium spp.), free living (Azotobacter spp.), associative symbionts (Azospirillum spp.) and endophytic non-nodular symbionts (Azoarcus and Gluconacetobacter diazotrophicus). In the recent past, phosphate solubilizing and phytohormone synthesizing bacterial communities also gained momentum.

Introduction
A significant challenge in the field of chemistry lies in the application of green methodologies aimed at enhancing the efficiency, cleanliness, and environmental sustainability of chemical processes in alignment with contemporary green chemistry goals. Recent global environmental issues have motivated researchers to create and implement more sustainable chemical practices to reduce the reliance on and generation of harmful toxic materials. The importance of coupling reactions lies in their role as effective and robust techniques for synthesizing key pharmaceutical agents, polymers, and natural products (Colberg, 2022). Crosscoupling reactions are particularly focused on the formation of C-C (carbon-carbon) and C-X (carbon-heteroatom) bonds. For the last three decades, cross-coupling chemistry has been widely utilized to facilitate the development, discovery, & market introduction of innovative types of pharmaceuticals and agrochemicals (Carsten Bolm, 2012).
In cross-coupling polymer reactions, two reagents equipped with activating functional groups engage with a specific metal catalyst, culminating in creating a new covalent bond. The loss of the activating groups carries out this process. In the 1940s, Kharasch and Fields first discovered the cross-coupling reactions using Grignards reagent with aryl or alkyl halides in the presence of metal halides such as NiCl2, CoCl2, FeCl3, CrCl2, or CuCl2 as a suitable catalyst. (Wu, 2021). Cross-coupling reactions have tremendous valuable applications in many vital areas, such as powerful tools for synthesizing essential pharmaceuticals, natural products, polymers, and agrochemicals. Furthermore, cross-coupling reactions have facilitated the synthesis of important molecules with industrial relevance, such as losartan, which is produced through a late-stage Suzuki cross-coupling reaction. Additionally, these reactions have created previously unattainable molecules, as the Suzuki coupling reaction ranks as the second most prevalent reaction in medicinal chemistry (Kotha, 2022). The predominance of sp2-hybridized carbon nucleophiles and electrophiles in most cross-coupling reactions has presented challenges in the pharmaceutical sector, as the “flattening” of many pharmaceutical targets results in a reduced number of specific drugs and an increase in off-target interactions. Nevertheless, crosscoupling reactions exemplify the capacity of robust synthetic methodologies to profoundly influence and inspire molecular design within the chemical industry. Recent trends in advances with the cross-coupling reactions are enabling the development of new reaction mechanisms, the synthesis of new compounds & development of new catalysts, and reactions that proceed under milder conditions.

Introduction
   
The major land mark in the primary food production is the Green revolution during sixties, eventually leading the country to self-sufficiency in food grains. At present, agriculture and allied sector contributes 22% of GDP in India. Total arable area in India is 184 million hectares contributing a total food grain production of 210.01 million tonnes. Horticultural crops including fruits, vegetables, flowers, plantation crops, spices and medicinal and aromatic plants have emerged as a major economic activity in India. Horticulture crops cover over 20.7  million hectares of area, which is approximately 11.25%  of the total gross cropped area of the country and contributes 18-20% of the gross value of India’s agricultural output. India is the world’s second largest fruit and vegetable producing country accounting for 81.29 million tonnes of fruit and 162.2 million tonnes of vegetables (Annon., 2013).

Introduction

• The green revolution of the 1960s and 1970s ended chronic food deficits and while cereals still command the attention of policy makers, fruit production has surged impressively, making India the second largest global producer behind China.

• Annual growth in horticulture has seen fruit production grow at faster rate and constitute the larger segment of agriculture. • No doubt, there has been manifold increase in area, production and productivity but when we compare the productivity of various major fruit crops with other developed countries, our productivity is very low.

• This may be mainly attributed by non-availability of quality planting material and seeds, existence of old unproductive seedling orchards, small and unirrigated land holdings, use of inferior genetic stocks/ varieties/hybrids, poor management and non-adoption of package of practices, high incidence of pest and diseases, heavy pre and post harvest losses and lack of trained human resource.

• To meet increasing demand the productivity per unit area per unit time and per unit investment has to be increased from limited land resources, where production and supply of quality planting material of elite varieties is one such important factor that can bring tremendous improvement in production, productivity and higher economic returns to farmers.

• This may be mainly attributed by non-availability of quality planting material and seeds, existence of old unproductive seedling orchards, small and unirrigated land holdings, use of inferior genetic stocks/ varieties/hybrids, poor management and non-adoption of package of practices, high incidence of pest and diseases, heavy pre and post harvest losses and lack of trained human resource.

Abstract

The structure and function of proteins involved in plant-microbe interactions is investigated through large-scale proteomics technology in a complex biological sample. Since the whole genome sequence are now available for several plant species and microbes, proteomics study has became easier, accurate and huge amount of data can be generated during plant-microbe interactions. Proteomics approaches are highly important and relevant in many studies and showed that only genomics approaches is not sufficient as much significant information are lost as the proteins and not the genes coding them are final product which is responsible for the observed phenotype.

Abstract

Production of healthy and vigorous seedlings is the foremost crucial step for raising a successful vegetable crop. Now a days seedlings are raised in trays under controlled atmospheric conditions called as transplants. As soil substitutes, artificial media made of perlite, vermiculite and peat moss are commercially available. A good rooting medium should be light weight, well drained, well aerated, and soilless with or without starter solution or added nutrients and with good water and nutrient holding capacity. The media should be sterilized before use. Selection of trays for cell shape, size and number depends on the type and nature of crop. Most of the vegetable transplants are now being produced in hardened plastic or polystyrene containers. Only good quality certified seeds should be used in media filled trays after priming, pelleting, coating or other seed treatments as per the crop requirement. Germination chambers as insulated rooms to maintain suitable conditions over large period of time may also be used. Generally vegetable crops need fertilizer application after expansion of first true leaf. Young seedlings are managed carefully to avoid any toxicity while taking care of their nutrient management. Water requirement also depends on growth stage and variation in weather conditions. Other seedling management practices include shading, thinning, weeding, disease/pest control, hardening off and subsequent transplanting. Containerized greenhouse plants can be grown using the conventional “rail” (or rack) system or the “float” system. Shipping factors such as mechanical injury, environmental conditions and length of storage affect plant vigour and establishments. IPM (integrated pest management) offers a practical way to effectively manage pests on vegetable bedding and transplants.

Introduction to Research

Research is an inseparable part of human knowledge. Its role in human life is as precious as that of salt in a vegetable. The life would lose its taste without research exactly in the same manner as a vegetable without salt. The modern academics just cannot stand and meet the aspirations of a matured society, if it does not provide for research and investigation. “The obvious function of research is to add new knowledge to the existing store. but its power for cleansing our minds of clinches and removing the rubbish of inapplicable theory is equally notable. Scientific research is a cumulative process. It is also a projective process, especially in the social sciences. Understanding can be (advanced) not only by gains in knowledge but also by discarding outworn assumptions”.

Introduction

Stored-product insects are serious pests of dried, stored, durable agricultural commodities and of many value-added food products and non-food derivatives of agricultural products worldwide. Various estimates on post harvest losses across the country revealed that there is loss of 2–12 per cent during storage exclusively by insects. Almost all the insect species may destroy 10.0 -15.0 per cent of grain and contaminate the rest with undesirable odour. The major loss is done by two internal feeders i.e. rice weevil and grain borer, which are major pests of rice, wheat and millets (Champ and Dyte, 1977). They also help in transportation of fungi (Sinha and Sinha, 1990). The losses during storage are quantity losses and quality losses. Quantity losses occur when insects, rodents, mites, birds and microorganisms, consume the grain. Infestation causes reduction in seed germination, increase in moisture, free fatty acid levels and decrease in pH and protein contents etc. resulting in total quality loss. Quality losses affect the economic value of the food grains fetching low prices to farmers (Das et al., 2013).

1. Introduction
Soils stand out as an intricate and diverse ecosystem on our planet. Their significance extends beyond supplying 98.8% of the world’s food, encompassing a wide array of essential services such as carbon storage, regulation of greenhouse gas emissions, flood prevention, and offering support to burgeoning urban populations. However, it is crucial to recognize that soil is a finite natural resource. The unprecedented growth of the human population, escalating from 250 million in the year 1000 to 6.1 billion in 2000, with projections reaching 9.8 billion by 2050, along with the intensified practices of agricultural production, is exerting immense pressure on the sustainability of soils.
For long-term sustenance the concept of ‘Soil quality’ was propagated around three decades back from now in the United States of America, and further expanded to the scientists of European and Asian countries. Soil health and soil quality are two interweaving term that signifies the potentiality or capacity of soil towards mankind. These two words complement each other in such a way that one term automatically comes with another to determine both aspects i.e. agricultural sustainability and environmental quality in terms of plant, animal and human health (Haberern, 1992; Doran, 2002). Idowu et al. (2007) remarked that the term “soil quality” is more favoured by scientists, whereas “soil health” is a term favoured by farmers as it connotes a holistic approach to soil management. The inception and application of soil quality term was officially approved by Soil Science Society of America (SSSA). They defined soil quality as “The capacity of a specific kind of soil to function within natural or managed ecosystem boundaries, to sustain biological productivity, maintain environmental quality, and promote plant and animal health” as illustrated by Karlen et al. (1997). It is a complex composition of certain properties associated with physical (texture, bulk density, water holding capacity, infiltration capacity etc.), chemical (pH, EC, organic carbon, extractable macronutrient and micronutrient etc.) and biological (microbial activity and related parameters) conditions of soil (Prabha et al., 2020). There are primarily two key methodologies for assessing soil quality: the descriptive approach, which focuses on characterizing various aspects or attributes of soil quality, and the Indicative approach, which aims to identify the ability or capacity of an attribute in a desired manner. The comprehensive process of developing a soil quality index is guided by the 3-Is framework: the Identification of indicators, Interpretation, and Integration of selected soil quality indicators. It is important to note that the specific set of indicators utilized can vary between different soils, diverse agroecosystems, and from one crop to another. Additionally, climatic conditions and other abiotic factors may also significantly influence the assessment of soil quality.
The USDA has categorized soil quality indicators into four primary groups: visual, physical, chemical, and biological indicators. However, in the current context, the dominant indicators are physical, chemical, and biological. For a systematic assessment of soil quality, it is crucial to collect individual parameters and integrate them meaningfully. Consequently, integrated soil quality indicators

Introduction

Humans and grass are inextricably linked to each other. The oldest unequivocal grass fossils are 25 million years old, originating in the Oligocene epoch (Thomasson, 1987). Grasses are one of the first permanent vegetation to reappear after disasters, such as volcanic activity, extended droughts, floods, fires, explosions, abandoned urban ghettos, and battlefields. In the past, landscaping was universally regarded as an extravagance for the affluent or as a decorative for mediocre and average structural design. Today, growers offer hundreds of selections for landscape designers who envision their backyard canvases swept with fulsome grasses. Countries are capitalizing on this industry at a furious pace and turfgrass research can be circuitously, the next moolah machine for enhancing lifestyle, real estate values and tourism revenues.

1. Introduction

Aquaculture has played a sustaining role in global food systems by providing expanded food production and livelihood benefits with relatively minimal environmental harm. (Igwegbe et al., 2021). To emphasize the importance of the aquaculture sector, the Food and Agriculture Organization of the United Nations (2020) stated that, global aquaculture production increased by 5.27%, hitting a record-breaking productivity value of 114.5 million tonnes between 1990 and 2018 (Pauly and Zeller 2017). Aquaculture has profited from developments in science and technology in nearly every aspect such as a greater diversity of species, nutritional regimes, production techniques, organizational frameworks, and marketing compared to other agricultural industries (FAO 2020). As an illustration, enhanced reproductive technologies have made it possible for individuals to achieve closed life cycles of aquaculture species, resulting in the diversification of species in the aquaculture sector (Weber and Lee 2014). The utilization of live feeds in hatcheries, such as microalgae, artemia, rotifers, brine shrimp, and various copepods, has eliminated the obstacle in breeding a variety of marine organisms (Conceição et al., 2010).

Approximately 60 varieties of fish species have shown significant improvements in features of economic value through selective breeding assisted by quantitative genetics (Zuma 2022). River shrimps (Levy et al., 2017), Yellow catfish (Roskoski et al., 1975), and mono-sex tilapias (Mair et al., 1997) all have been produced owing to sex reversal technology and DNA markers linked to sex determination. The risk of inbreeding has decreased due to intrafamily screening being made possible by molecular parentage assignment (Xu et al., 2020). Selection for characteristics, particularly are governed by single genes and a small number of significant genes (Fuji et al., 2007; Houston et al., 2008) has been made possible by QTL (quantitative trait locus mapping) and marker-assisted selection (MAS) (Yue 2014). Enhanced feed formulations dependent on the dietary needs for every fish species have enhanced feed conversion rate (FCR) and decreased feed cost (Tacon and Metian 2015). Innovations for disease control (Kelly and Renukdas 2020) have minimized the prevalence of ailments in aquaculture.

Introduction 
Over the past few decades, magnetic nanoparticles (MNPs) have been showing great importance in the field of organic synthetic reactions, catalysis, sensors, biomedicines, environment rehabilitation, etc. (Gawande, M. B. et al., 2013; Del Rio, M. et al., 2022). Numerous research teams have recognized the significance of solid support materials for the creation of environmentally acceptable nano catalysts with high catalytic activity in light of the infinite advantages of MNPs (Sharma, R. K. et al., 2016; Gawande, M. B. et al., 2013; Deng, J. et al., 2011; Nasrollahzadeh, M. et al., 2015; Hudson, R. et al., 2014; Payra, S. et al., 2017; Chng, L. L. et al., 2013; Parandhaman, T. et al., 2017; Zhang, F. et al., 2014; Pourjavadi, A. et al., 2012). Heterogeneous catalysts in organic chemistry are solid catalysts that, while remaining in a distinct phase (usually solid) from the reactants (generally liquids or gasses), promote chemical reactions without being consumed in the process. These catalysts, which have multiple benefits such as ease of separation, recyclability, and selective reactivity, are essential in a variety of industrial processes and laboratory reactions (Lattuada, M. et al., 2007; Jiang, K. et al., 2011). The standard formula for ferrite nanoparticles is MFe2O4, where M is usually divalent metal ion like copper (Cu), zinc (Zn), or nickel (Ni), and iron (Fe) is the common metal (Kazemi, M. et al., 2018). These nanoparticles work very well as heterogeneous catalysts in a variety of chemical reactions because of their special magnetic and electrical characteristics.Because of its special qualities as a catalyst in a variety of processes, copper ferrite (CuFeO4), a mixed-metal oxide, has drawn interest in organic chemistry (Kharisov, B. I. et al., 2019; Zhu, J. et al., 2014; Vannucci, A. K. et al., 2012). It is a spinel-type ferrite that can catalyse a variety of organic transformations because it combines iron and copper in a stable, highly active structure. With benefits including high stability, reusability, and low toxicity, these catalysts are frequently employed in processes like oxidation, coupling, and reduction (Taghavi Fardood, S. et al., 2018). The Figure 1 represents schematic diagram of a reaction where the ferrite nanoparticles as catalyst have been recovered with the aid of an external magnet after the formation of reaction product.

Introduction

One of the remarkable advancements in veterinary medicine recently is the application of interventional cardiology techniques to treat various congenital heart diseases. In dogs and cats, congenital heart diseases can be treated much more easily and with fewer complications using minimally invasive interventional approaches, rather than through traditional open-heart surgery. Among congenital heart diseases, treatment options are available for conditions such as PDA (Patent Ductus Arteriosus), AS (Aortic Stenosis), PS (Pulmonic Stenosis), VSD (Ventricular Septal Defect), ASD (Atrial Septal Defect), extrahepatic shunt, and stem cell applications. These diseases often cannot be significantly improved by medical treatment alone, making the use of the aforementioned interventional techniques essential for effective management.

The management of diseases and pests is a major challenge. Monoculture, excess use of fertilisers, high- yielding varieties, climate change etc have not only intensified plant diseases, but also given rise to new diseases or intensified those diseases which were earlier considered of minor importance. Although decades of research have given rise to certain promising organic and biological alternatives to chemical disease management, due to the lack of proper attention of researchers worldwide, the organic and biological disease management technologies are still not very popular.

Mastitis is a consequence of interplay between the infectious agents and managerial practices. The mammary glands of cows are frequently exposed to potential pathogens, but on most of the occasion, cows get mastitis because their immune systems are not adequate to prevent infection. Mastitis is an inflammation of the mammary gland in response to injury for the purpose of destroying or neutralizing the infectious agents and to prepare the way for healing and return to normal function. The average incidence of subclinical mastitis has been found to be 49% in cows and 28% in buffaloes. Similarly, clinical mastitis is prevalent in 7% of cows and 4% buffaloes. Besides this, 17% of the cows and 8% of buffaloes have been suffering from various udder and teat lesions such as udder/teat warts, bovine ulcerative mammilitis, udder impetigo and teat chaps etc. These lesions pre-dispose the animal to mastitis and cause a great discomfort at milking and hence markedly decrease the milk yield. The economic losses due to mastitis worldwide have been estimated at $35 billion. Current annual economic losses due to mastitis in India have been estimated to be Rs. 7165.51 crore that include Rs. 4151.16 crore and Rs. 3014.35 crore due to subclinical and clinical mastitis, respectively. Mastitis causes a reduced milk production, not only at its occurrence but throughout the rest of the lactation, increases the risk of new cases of mastitis and increases the risk of culling. Besides, mastitis impairs the quality of milk and milk products. Approximately 70-80% of losses are due to subclinical mastitis. Subclinical mastitis is also important due to the fact that it is 15-40 times more prevalent than the clinical form. It usually precedes the clinical form, is of longer duration, difficult to detect and constitutes a reservoir of micro organisms that lead to infection of other animals within the herd.Besides this, presence of mastitis causative organisms and antibiotic residues in milk following therapy of mastitis poses a major threat to the consumer health. Mastitis results in increase in the somatic cell count (SCC) and bacterial load of milk. The European Union has set up a threshold of 400,0000 cells/ml of milk from healthy quarter of a cow. The high SCC in mastitis milk has lipolytic effect on fat and there is increased tendency for rancidity of milk and milk products. Also, the mastitis milk with total bacterial count of more than 100,000 cfu/ml could release hydrolytic enzymes, which spoil the milk and milk products. It has been also observed that mastitis milk inhibits the growth of starter bacteria and results in decreased cheese production.

AGRI BUSINESS MANAGEMENT

Agribusiness is a generic term. It includes food production, farming, seed supply, agrichemicals, farm machinery, wholesale and distribution, processing marketing and retail sales. John. H. Davis of Harvard University first used the term Agribusiness in 1955. Prospects of agri-business India (McKinsey and Confederations of Indian Industry 1997)    
Food industry offers one of the largest opportunities in India today
By 2005 - 07, the food industry will grow three fold to reach us 70 $ billion, and increases in forthcoming year. India can be the world Largest Food Factory
   
India’s food production today is equal to that of USA, second to China
Value added foods will grow faster rates ($30 to $60) million.
Growing the food industry will raise agricultural yields, increases income and create employment and economic development.

The Indian subcontinent has a vast costal belt along with the wide range of forest environment, which host large number of unexplored plant/marine species. This diversity has been the source of unique chemical compounds with the potential for industrial development as pharmaceuticals, cosmetics, nutritional supplements, molecular probes, fine chemicals and agrochemicals. In recent years, a significant number of novel metabolites with potent pharmacological properties have been discovered from the natural sources including marine and terrestrial plants. Recent move of society towards nature for the treatment of various diseases where there is no satisfactory cure in modern medicine has diverted the attention of natural/medicinal chemists and biologists to unravel their chemical characteristics and biological activities together in order to define their therapeutic potential in the light of modern pathobiological understandings. This move has led collectively to rediscover, design and refine the therapeutic application of medicinal plants/marine sources.

Introduction

The United Nations’ Food and Agricultural Organisation reported that global aquaculture is increasing by 11 percent per year and is the world’s fastest growing food-producing sector. More than 38 million people are employed in aquaculture and associated industries worldwide, and 131 aquatic species are currently being commercially cultured. In 2002, Asia led the world in the aquaculture production, with about 12.4 million tonnes, while Europe and America together produced 1.2 million tonnes.

Among the Asian countries, India ranks second in aquaculture and third in capture fisheries. Freshwater aquaculture in India is mainly based on Indian major carps (Labeo rohita, Catla catla and Cirrhinus mrigala) with an annual production of 1.8 million tonnes, and exotic carps, which together contribute to over 87% of the total aquaculture production of 2.2 million tonnes. Disease problems represent important constraint to the aquaculture industry. The need to control endemic diseases imposes severe year-on-year costs on producers. The advances made in the development of vaccines for diseases of Indian major carps are very meager.

Abstract

Food lost during the production chain is referred to as postharvest loss. Reducing postharvest loss can effectively feed starving mouths while conserving resources and decreasing the pressure to produce more. There are five main areas where postharvest loss can be reduced – harvest, storage, transportation, processing, and retail. New approaches and technologies in each of these areas will increase the amount of food available for human consumption. The total loss due to poor post- harvest processing of agricultural products in India when valued in terms of monetary reflects a tremendous loss in the economy. Annual value of harvest and post-harvest losses of major agricultural produces at national level to be of the order of Rs. 92,651 Crore calculated using production data of 2012-13 at 2014 wholesale prices. Deficits in food items or financial loss should not have occurred if postharvest losses were reduced through proper processing and preservation from harvest to consumption. Both the government and private sector need to invest in research so as to improve and modernize post-harvest facilities for attaining more efficient market infrastructure and distribution channels. Research and extension activities have to be closely coordinated particularly in the public sector for the benefit of farmers, traders and consumers.

A high-yielding cultivar Vallabh Medha of mandukparni (Centella asiatica) was identified. Fresh herbage yield (12,331 kg/ha) and dry herbage yield (2,113 kg/ ha) of this variety were far more than the local variety (2,050 and 392 kg/ha respectively), besides higher active ingredients. Among mucuna selections, IIHR PS 15 with long duration, IIHR PS 6 with medium duration and IIHR PS 14 with short duration recorded significantly higher yield and high L-dopa yield/ plant. In Coleus, a promising hybrid, Hy 08-53, recorded significantly higher root yield (60.22g) and higher forskolin yield/plant (0.58 g). In ashwagandha, IIHR- WS 3 was found to be the best yielder (11.65 q/ha).

Isabgol (Plantago ovata Forsk.)

The crop requires cool and dry climate during the growing season. Sowing of seeds at 4 kg/ha in 0.25-0.50 cm depth during November 20 to December 20 was recommended. In medium black cotton soil of Malwa region, second week of November was reported to be optimum time for sowing. Broadcasting of seeds followed by light sweeping with broom found to give uniform germination. A spacing of 30x 45 cm found to be most ideal to get higher seed yield in Isabgol under Madhya Pradesh situation. Response of chemical fertilisers was found low. However, a fertiliser dose of 25 kg/ha each of N and P₂O₅ as basal dose and 25 kg/ha N as top dressing at 30-42 DAS was recommended for commercial cultivation in Gujarat while 50 kg/ha N reported to increase the seed yield in Madsaur areas of Madhya Pradesh. At Anand three irrigations viz. first at the time of sowing and subsequently at 30 and 70 days after sowing (DAS) proved to be beneficial. However, four irrigations at sowing, 10,25, and 50 DAS at Mandsaur are recommended. Chemical weed control was found to be economical and a pre-sowing or pre-emergence application of Isoproturone (0.5 kg ai/ha) was recommended for weed control. One spray of Metalaxyl + two sprays of Mancozeb were found significantly superior in controlling downy mildew. In Gujarat, Pearl millet in Kharif and Isabgol in Rabi season are advocated as a suitable crop rotation. Groundnut-Isabgol rotation gave higher economic return followed by Soybean-Isabgol and Pigeon pea-Isabgol rotations in Maharashtra.

High-yielding crop varieties and hybrids with tolerance to pests /diseases and to various farming constraints such as soil and water salinity, soil acidity, drought, flood and such other factors have been developed.

Eight cardamom hybrids, NKE 12 × MB 5 (1,499 kg/ha), MB 5 × NKE 19 (1,461 kg/ha), GG × NKE 12 (1,350 kg/ha), RR 1 × CCS 1 (1,245 kg/ha), CCS 1 × RR 1 (1,022 kg/ha), ASH (1,930 kg/ha), NKE 12 × GG (1,746 kg/ha), GG × NKE 19 (1,635 kg/ha), were identified for high yield and resistance to mosaic and rhizome rot diseases. Two unique mutants, AFg-3 and AFg-4, for powdery mildew resistance were isolated in fenugreek. In ajwain, AA 93 has been developed which flowers 40 days earlier compared to other varieties. Thirty- two elite saffron clones were selected and evaluated for fresh and dry weight of pistil, stiga and style length, and weight. CITH 125 (4.5 kg/ha), CITH 123 (4.3 kg/ha), CITH 124 (4.3 kg/ha), CITH 122 (4.0 kg/ha), CITH 12 (4.5 kg/ha), CITH 121 (3.9 kg/ha), CITH 107 (3.8 kg/ha), CITH 120 (3.8 kg/ha) and CITH 104 (3.7 kg/ha), having higher saffron yield were identified.

High-yielding Plantation crops varieties and hybrids with tolerance to pests / diseases and to various farming constraints such as soil and water salinity, soil acidity, drought, flood and such other factors have been developed.

Three coconut varieties (IND 045S, IND 048S and IND 058S), two arecanut varieties (VTL 62-Shriwardhan selection and VTL7-Nalbari) and two selections of cocoa (VTLC 1 and VTLC 57) were identified for commercial cultivation. Coconut variety, Kalpa Samrudhi, was recommended for commercial cultivation in Kerala and Asom, and Kalpa Sankara and Kalpasree for coconut root(wilt)- affected tracts in Kerala. Molecular-markers associated with hybridity in coconut, dwarfness and resistance to root (wilt) and yellow leaf diseases were utilized. Homology-basedmodelling of somatic embryogenesis receptor-like kinase (SERK) protein in coconut, development of a computational tool for detection of microsatellites in whole genome sequences, development of algorithm for gene annotation and genome-wide analysis of microsatellites in strains of plant growth promoting (P. fluorescens) are achievements in bioinformatics.

Cost-effective farming systems for spices cultivation for increasing production and productivity in different agro ecologies have been developed.

An organic package for production of black pepper, ginger and turmeric by applying farmyard manure, vermicompost, ash, rock phosphate, Azospirillum sp. and phosphobacteria and Trichoderma sp. and Pseudomonas sp. as biocontrol agents for disease control was developed. Further, a foliar spray of 1% solution of complex fertilizer 19 : 19 : 19 (N : P : K) during spike initiation period (April second week, May first week and May fourth week) during lean cropping season under irrigated condition enhanced black pepper (cv. Panniyur I) yield by 20–25%. Soil application of zinc up to 10 kg/ ha or foliar spraying of ZnSO4 (0.25%) and Borax (0.2%) twice (60 and 90 days after planting) was recommended for higher yield and quality for turmeric in zinc and boron deficient soil.

Among all the treatments, sprinkler and drip irrigation methods caused early sprouting; early flowering with increased plant height and more number of leaves and flowers/plant as compared to the control (rainfed). Also, stiga fresh weight, dry weight, length and saffron yield were improved in sprinkler and drip irrigation methods over the control. Raised beds resulted in early sprouting, early flowering with increased plant height and more number of leaves and flowers/plant.

Cost-effective farming systems for plantation crops cultivation for increasing production and productivity in different agro ecologies have been developed.

In coconut-based cropping system, elephant-foot yam cv. Gajendra yielded high amount of corm. Guinea grass (var. GGCo 3) produced higher green fodder (89.2 tonnes/ ha/year) under husk application. There was lower specific volume of soil and soil porosity (higher soil compaction), and soil dehydrogenase activity (an index of biological activity) as important abiotic pre-disposing factors in incidence of root wilt disease. Growing Gomphrena globosa as intercrop in root wilt- affected coconut gardens has been shown to be cost-effective and sustainable. In areca-based mixed farming system, total cash inflows and outflows from arecanut + dairy (3–4 milch cows) amounted to ‘4.41 and ‘5.96 lakh, with a net profit of’1.55 lakh. The system productivity of arecanut + cocoa system (3,127 kg/ha) was 30% higher per unit area than arecanut alone (2,405 kg/ha). Integrated nutrient management on four improved arecanut varieties recorded highest chali yield (4.19 kg).
