Ber (Ziziphus mauritiana Lam.) is one of the most ancient and important fruit crops. It is considered as the “King of arid zone fruits”, due to its adaptations to tolerate the biotic and abiotic stresses prevailing under rainfed conditions (Anbu et al., 2009). It is also called as desert apple, jujube, Badari (Sanskrit), Chinee apple, Ber (Hindi), Kul or Boroi (Bengali), Indian plum, Boroi, Beri, Permseret (Anguilla) etc. It is a tropical fruit tree that belongs to the family Rhamnaceae. Ber is rich in amino acids, protein, sugar, calcium, phosphorus, carbohydrates, iron, vitamin A, ascorbic acid. The fruit contains from 70 and 165 mg ascorbic acid per 100 gm of pulp, which is two to four times higher than the vitamin C content of citrus fruits. The mineral content of phosphorus, calcium and iron in Z. mauritiana fruit is also reported as being higher than in apples and even oranges (Morton et al., 1987, Jawanda and Bal,1978).

Introduction

Agriculture is the backbone of Indian economy. There are a number of sub sectors in the agricultural sector such as sericulture, floriculture and horticulture. Among those fields horticulture has played a dominant role in the total agricultural output throughout India. The world market has provided a good opportunity for the development of the fresh and the processed fruits industry of India. From the point of view of domestic market also, horticulture products have provided food items of nutritional value. Their cultivation has generated higher employment opportunities and higher returns to the farmers than the cereals and other agricultural cash crops (Singhal, 1995). Mango (Mangifera indica) is a stone fruit belonging to family Anacardiaceae. It is a most important fruit of India and known as the “king of tropical fruits”. Mango is cultivated in many tropical regions and distributed widely in the world. 

Introduction

There are forty different edible oilseeds which can be used for edible and non-edible purposes. Out of which nine oilseeds are extensively used for edible and non edible purposes. The oilseeds such as groundnut (peanut), sunflower, sesame, soybean, rapeseed-mustard, niger and safflower are generally used for edible purposes and castor and linseed are used for non-edible purposes. Plants are the main source for 71 percent of edible oil. Some oil crops such as groundnut (peanut) and sesame can be used directly as food and edible oil, but others are mainly processed to obtain oil, and oil cake or meal (Hetje, 1989). The oil crops are grown all over the world (Girish Kumar, 2012). Area under cultivation of edible oilseeds in 2020 was 27.14 million hectares. The total production was 33.22 million tonnes with the productivity i.e. yield per hectare of 1025 kilogram per hectare in India (Ministry of Statistics). India is the world’s largest importer of edible oil (Santosha, et. al., 2017) and the import of edible oil in 2020 was 93.37 million tonnes.

Before proceeding to find out the nature of the egg content of the faecal sample, one should know what class of animal the faecal sample belongs to. It is easy to identify a faecal sample of herbivore from that of an omnivore or a carnivore. The dung of cattle, sheep and horse will contain lot of vegetable fibers. The colour of the dung under normal conditions will be dark greenish yellow with a peculiar aromatic smell. But the faeces of a dog or cat will be soft and pasty devoid of fibers and dark yellow in colour with an unpleasant smell. Several procedures commonly used to examine faeces for parasites are described in this section. Before attempting to apply these procedures, a few points should be considered:

Collection of blood Blood sample should be collected in a capped clean and dry vial containing an appropriate amount of anticoagulant. The commonly used anticoagulants are ethylene diamine tetra acetic acid (EDTA) @ 1-2 mg/ml and heparin @ 5 I.U./ ml of blood. Sites for blood collection Before collection of blood clean the site of collection by applying some antiseptic solution. If the area is hairy shaving of the site under aseptic condition should be done. Tip of the ear should be preferred for prompt or early diagnosis of haemoprotozoan infections. The vein can then be punctured with hypodermic needle and the collected blood is transferred to a clean glass vial. For collection of blood various preferred sites in different animals are as under

Introduction Papaya fruit is listed under the family Caricaceae. This family has total four genera all over the world. There are about four species found in India under the Carica L. genus. Carica papaya L. is one of the species among them and it is most widely cultivated and very well-known species in India (Kumar and Devi, 2017). It has a thin, little shiny, and green-colored peel which turns into orange colored after ripening. The size of the fruit varies from 5.5 to 5.9 cm in terms of diameter. Papaya has several industrial applications in food processing, pharmaceutical as well as cosmetic industries. According to the FAO (Food and Agriculture Organization, 2013), India, Indonesia, Brazil, the Dominican Republic, Nigeria, and Mexico are the countries that produce the largest number of papayas in the world, India being the largest producer (4457.1 tonnes) followed by Brazil (1859.3 tonnes) in the year 2011.

Introduction Consumer demands for convenience and mildly processed meals with long shelf lives have led to unique and current developments in food packaging solutions (Dobrucka and Cierpiszewski, 2014). Additionally, the development of unique and creative packaging solutions that do not compromise food safety or quality is being fueled by the current retail trend and changing lifestyles (Dainelli et al., 2008). The widespread use of packaged meals has raised consumer demand for prepared foods like microwaveable dinners, and the growing popularity of smaller food packages all help to fuel the food industry's explosive growth in creative packaging (Restuccia et al., 2010). The rise in food-borne microbial outbreaks, which calls for the usage of packaging that possesses antimicrobial qualities while retaining food quality, is another major driver of new food packaging (Appendini and Hotchtkiss, 2002). The initial advancements in packaging were electrically powered packing equipment, flexible packaging, metallic cans, aseptic packaging, aluminium foils, and flexographic printing. A considerable movement away from metal, paperboard, and glass packaging in favour of plastic and flexible packaging was also brought about by the discovery of various materials such as polyester, polypropylene, and ethylene vinyl alcohol polymers.

Introduction Cabbage (Brassica oleracea var. capitata) belongs to the family Cruciferae or Brassicaceae having chromosome number 2n=18. ‘Cole wart,’ a wild non-heading variety of Brassica oleracea var. sylvestris, is the ancestor of cabbage. The majority of the 100 species that make up the genus Brassica are indigenous to the Mediterranean region. It is also believed that Germany is where the true-headed cabbage originated. Currently, mostly cabbage is grown in the country like Caribbean, Indonesia, Malaysia, Central Asia, and Western and Eastern America.The third-largest producer of cabbage worldwide is India. The majority of the nation’s states where it is grown include UP, Orissa, Bihar, Assam, WB, MH, and Karnataka. Annually in India, cabbage was produced around in the area of 418 thousand hectares and production of 9.72 million metric tons with the productivity of 22.7MT/hectares (NHB, 2021-22). The other main producers in the globe, in addition to India, are China, Russia, Japan, Korea, the USA, Indonesia, and Ukraine.

Introduction Garlic (Allium sativum L.) belongs to the monocotyledonous family Alliaceae or Amaryllidacea; Chromosome No. 2n=2x=16. In India, it is the second most extensively grown bulb crop after onion. According to several botanists (Candolle, 1985; Dscalov and Popov,1941; Kuznetsov, 1948 and Regel, 1975) garlic was cultivated and utilised by Mediterranean population since medieval time. Origin, History and Distribution Central Asia, particularly elevated highland of Pamir and Tian Shan is considered as the primary centre of origin of garlic (Vavilov, 1926), however Caucasus and North Africa is considered as the secondary centre of origin. Allium longicuspis is considered as the wild ancestor of garlic. The history of garlic usage dates back to 3000 B.C when it was used in Egyptians tombs likewise its first usage in modern era occurred during 10th century in England (Shinde and Sontakke, 1986) and its first introduction in North and South America was done by Spanish and Portugese settlers during fifteenth century; introduction and usage of garlic in other European and Asian countries occurred subsequently.

Introduction The botanical name of carrot is Raphanus sativus which belongs to the family Brassicaceae having haploid chromosome number of x = 9 and is believed to be originated from Europe and Asia. Radish is one of the most ancient and popular leaf cum root vegetables in both tropical and temperate regions. Radish probably originated in Europe and Asia. Radishes were extensively cultivated in Egypt and ancient records show that radishes were eaten before the pyramids were built. It had spread to China during 500 BC and to Japan during AD 700. The recent study has indicated that east of Mediterranean region, most probably China is the centre of origin of radish. Wild state of radish is not known. Previously it was believed to haveevolved from a common weed Raphanus raphanistrum Linn in Europe but now it is believed to have been evolved from more a variety of sources. As it is a short duration annual or biennial crop, it can be widely used in sequence cropping, companion cropping and intercropping in widely spaced crops. Roots are pink in colour due to presence of anthocyanin pigment.

Introduction The Globe artichoke is a herbaceous perennial crop that is grown for its tender, edible, immature flower buds. It is botanically known as (Cynara scolymus L.) and having chromosome number 2n=2x=34. The globe artichoke belongs to the family Compositae, and it originates in the Mediterranean Basin, where it was most likely introduced as a crop in about the first century AD (Sonnante et al., 2007). The globe artichoke is presently grown as an annual crop or a perennial crop in different regions of the world. The increasing demand for globe artichokes as a source of pharmaceuticals and modern functional foods has created new challenges for producers, necessitating the concurrent development of new production hubs and the use of cutting-edge technology in established growing regions that can support the global market.

1. Introduction Millets, one of the earliest foods consumed by humans, may have been the first cereal grain utilised in domestic cookery. It belongs to the Graminae grass family. The name “millet” describes a number of little-seeded grasses (annual) that are classified into five genera: Setaria, Panicum, Pennisetum, Paspalum, and Echinocloa in the tribe Paniceae, and one genus: Eleusine in the tribe Chlorideae (Pushpavalli, 2015). India ranks first in the production of millets followed by Niger and China (FAO, 2020). Pearl millet (Pennisetum glaucum) serves as food, fuel, and fodder on a global scale. Since, it contributes up to 75% of all grain output in East Africa and several regions of India; it plays a significant role in indigenous diets. After rice and wheat, pearl millet is the third most significant crop farmed in India. Ninety percent of the country’s land is used for cultivating pearl millet, with Rajasthan, Gujarat, Maharashtra, Uttar Pradesh and Haryana being the main states.

1. Introduction Fonio (Digitaria exilis), also known as acha, hungry millets, and fundi in various regions, is a minor and underutilized millet with exceptionally small size (H. Sartelet et al., 1996; Bello et al., 2020). This ancient crop native to West Africa is considered one of the oldest cultivated millets for ensuring food security. Figure 1 illustrates the components and structure of fonio millets. In recent times, fonio millet has garnered increased attention due to its remarkable nutritional and functional properties (Zhu, 2020). Being gluten-free, it is rich in nutrients such as carbohydrates, fat, fiber, vitamins, and minerals (Fe, Cl, K, Mg) as well as essential sulphur-containing amino acids like methionine and cysteine, which also possess phenolic properties (Barikmo et al., 2004; Zhu, 2020).

Background The Enormous diversity of our planet harbors individuals of the sexually reproducing population that are unique and non-identical in nature. This unique nature is the source of this vast diversity. Taxonomy is critical for identification and classification. The oldest of the scientific disciplines, taxonomy, isdescribed as the theory and practice of classifying organisms (Mayr, 1982; Mayr and Ashlock, 1991). Taxonomy is a branch of systematics that deals with the idea and practice of classifying and describing diversity (Nelson, 2006). According to the global estimates of species (Mora et al., 2011; Costello et al., 2013), 1.2-1.5 million species are considered to be described and valid to date (Costello et al., 2013; Mora et al., 2011; Zhang et al., 2011). The enormous and intriguing variation among the species, as well as anatomical differences between species, developmental stages, and geographical ranges, make identification difficult. Rapid documenting of biodiversity should be a top priority before it is lost. This necessitates quick and accurate taxonomic expertise as well as enhanced identification methods, paving the way for the emergence of Integrative taxonomy (Dayrat, 2005), which combines all available data, whether morphological, behavioral, ecological, or molecular.

Temperature is the measure of the thermal state of a body with respect to its ability to transfer heat. Soil derives its heat almost entirely directly from the sun and losses much of it back into the atmosphere. The major processes for heat transfer in soil are: Radiation, Convection, Conduction and Latent heat exchanges between soil and atmosphere. The most important source of which is the incident radiation supplying almost all the heat energy for the biosphere and also determines the thermal regime of soil. Soil temperature or thermal regimes of soil is an extremely important property of soil as it regulates plant growth directly and influences moisture and aeration status in soil, soil structures, microbial activities and decomposition of plant residues and the availability of plant nutrients . It is controlled mainly by its thermal properties and radiation exchange over the surface and their variations within the soil. The quantity of incident solar radiation and heating the soil depends on the several factors such as exposure and latitude, albedo, soil colour, slope vegetation and composition of soil.

Soil acidity is most conveniently measured by pH of soil suspension with water. Pure water undergoes dissociation into hydrogen and hydroxyl ions and are in equilibrium with undissiociated water molecules Thus, H2 O ??? ??? H+ + OH- (1) and in presence of another H2 O molecule, H+ converts to H3 O+ H+ + H2 O ??? ??? H3 O+ (2) Since water is a weak electrolyte and dissociates as per Eqn. 1, the ionic product of water can be written as – KW = aH+ x aOH- = (CH+ x COH– ) x ( fH+ x fOH-) (3) where, a, C, and f represents the activities, concentrations and activity coefficients of respective ions. In pure water and in dilute solutions the activity coefficients are approximately unity thus the product of concentrations of H+ and OH-1 is the ionic product of water and at ordinary temperature (250 C) this has a constant value of 10-14 gm ions per litre so, Kw =(CH+ x COH–1) = 10-14 gm ion per litre (4) such that, CH+ = COH–1 = 107 gm ion per litre Therefore, if hydrogen ion concentration of an aqueous solution exceeds this value, (10-7gm ion per litre), the solution is said to be acidic then there will be a proportionate decrease of OH- concentration to maintain the constant value of ionic product.

In order to assess the economic value of biochar, various factors need to be taken into account, including production expenses, market demand, potential income sources, and cost reductions. The economic worth of biochar can be determined by considering these factors.

8.1 Production costs

The cost of producing biochar can differ based on various factors such as the type of material used, the scale of production, the method of pyrolysis used, and the particular operational conditions.

i. Feedstock costs

• The cost of acquiring or producing biomass feedstock includes purchasing agricultural residues, forestry waste, or other biomass sources. Additional costs such as land, seeds, fertilizers, and harvesting should be considered using dedicated energy crops.

Introduction

Irrigated agriculture plays a predominant role in the state’s food grain production. Erratic trend of rainfall, it has been realized that the availability of water will become very less in forthcoming days as a result cultivation of crops will face water crisis. Development of new water resources needs excessive money investment with high level of expertise and technical knowhow. The ground water is also falling down to greater and greater depth due to overdraft causing for the restriction of the construction of tube wells. Further the efficiency of traditional irrigation system in India is now varying from 30% to 40% against 62 to 65% during the project plan periodbecause of wastage of this valuable water resource due to mismanagement. To meet the increasing demand for additional food grain production, the demand for water in the irrigation sector will increase substantially. In such a situation conservation of water and its proper management is necessary for developing a sustainable agricultural system avoiding the degradation of the land quality, water and other natural resources in an irrigated area.

Biomass, a diverse and renewable resource, holds immense potential as a source of energy, feedstock, and environmental solutions. However, effectively harnessing its benefits necessitates a systematic approach. This chapter introduces the concept of Biomass Management Techniques as a pivotal framework for optimizing the utilization of biomass resources. With a focus on sustainable practices, this chapter delves into various techniques to handle, process, and utilize biomass efficiently. From collection and transportation to storage, conversion, and beyond, Biomass Management Techniques encompass a wide array of methods that ensure the seamless integration of biomass into energy generation, industrial processes, and environmental conservation.

Introduction

Recognizing the importance and impact initiatives were taken for starting National Horticulture Mission, announced by Honorable Prime Minister on 15 August 2003. Crop diversification has become an imperative for India’s agri-economy. To address this need and to give further impetus to encouraging growth in cultivation of horticultures, vegetables, flowers, species etc. a National Horticultural Mission has been launched. Its main target will be doubling India;s horticultural production by 2010. Sub sequentially, National Horticuture Mission was launched during Tenth Plan with effect from 2005 2006 for holistic development of horticultural crops, having competitive advantages.

Background

Analysing changes in the cropping patterns is an important prerequisite for optimization and evaluation of water use efficiency and water resource management. Cropping pattern changes in India could not only be seen as resulting from the pursuit for higher economic returns, but also as a feedback response to limited water resources. Although a systematic framework is still needed for future cropping pattern planning in the country by taking food security, continued agricultural expansion and other constraints into consideration, the existing cropping pattern may provide an insight with which alternative cropping patter may be proposed for a right intervention in enhancing water productivity and food security.

1. Introduction

Agriculture is the backbone of the economy and a significant sector. For all nations, agriculture digitization is a growing area of concern. The need for food rises in tandem with the world's population growth, which is happening quite quickly. The agriculture sector is finding it very challenging to develop methods and strategies that will enable them to completely meet the growing wants and specifications due to the expanding need for food and shifting consumer preferences. Misuse of agricultural components can have detrimental effects on the environment and cause pollution. Farmers mostly rely on irrigation canal networks, groundwater, and rainfall in the field of irrigation. 

Introduction

India possesses abundant human resources due to its demographic dividend. With a population of approximately 1.39 billion, rural areas are home to about 68.84% of the total population, constituting more than two-thirds (Census 2011, GoI). According to the National Sample Survey Office (NSSO) in 2019, about 58.3% of rural households rely on agricultural activities as their primary source of income. Despite the significant reliance on agriculture for livelihoods, the agricultural situation in India is challenging.

Agronomical practices is the collection of operations starts from field formation, tillage, sowing, irrigation, manure and fertilizer management, pest control and harvest etc. Though, the type of agronomical practices varies with the crop, the basic function of various agronomical operations remains the same for all the crops. Considering that, understanding the basics of general agronomical practices is crucial for good agricultural practices and optimum production.

Tillage

Tillage is the basic activity of preparing the land for the crop production.

Poultry is one of the most emerging growth components of Indian agriculture, with egg and meat production rising at the rate of 8-10% per year when compared to crop production (1.5 - 2% each year). In India, the poultry population stood at 851.81 million in the 20th livestock census, an increase of 16.8% over the 19th census. Poultry sectors contribute 1% of national GDP and 25% in livestock GDP (FAO, 2021). According to DAHD’s 2022 report, our nation produces 122.05 billion eggs and 4.47 million tonnes of poultry meat altogether. India ranks eighth in terms of total meat production and third in terms of total egg production (DAHD, 2022).

Departure of waves ( P,Q,R,S, T), segments (P-R, S-T and T-P) and /or intervals (P-R, Q-T, R-R) from their normal values (configuration, morphology, amplitude and duration of wave; prolonging /shortening of intervals : elevation /depression of segments from their isoelectric line) is said to be abnormal feature of the electrocardiogram. These abnormalities are suggestive of specific cardiac abnormalities such as a defect in the current generation, its conduction or both; or change in the size of the chambers (atria / ventricles/both.).

Though the treatment for arrhythmias has been recommended for even a single premature beat, in the current scenario the treatment is indicated when there are more than 17 VPCs per minute. In certain situations the side effects or proarrhythmic effects of drugs can lead to morbidity or mortality. As a result, new guidelines are proposed when evaluating the need for treatment of arrhythmias. Keeping the adverse effects of antiarrhythmic agents in mind, one should be selective about which arrhythmias are to be treated. The goal of antiarrhythmic therapy includes the treatment of an existing arrhythmia or prophylaxis for anticipated arrhythmias.

Introduction

The global aquaculture and fishery industry is a substantial business, valued at USD 281.5 billion, yielding an impressive 122.6 million tons of aquatic products in 2020 (FAO, 2022). Asia is the largest aquaculture producer, contributing to almost 91.6% of the world's total production (FAO, 2022). Forecasts indicate that aquatic animal production is poised to grow by an additional 14% by 2030 (FAO, 2022). Despite this growth, there remains a pressing need for technological advancements to address critical challenges like water pollution, disease outbreaks, the quality of breeding stock and juvenile fish, and inadequate management practices (Fearghal, 2019; Michael, 2019).

Introduction

The emergence of the green revolution highlighted the significance of agricultural communication. Its strategy and attitude were modified to reflect the priorities of contemporary agriculture. Earlier attempts at agricultural journalism drew their power mostly from agricultural extension rather than journalism or mass communication. The primary objective was to provide farmers with a collection of techniques authored by scientists or subject matter experts about a variety of crops. Due to the lack of synergy between journalism and extension, agricultural journalism stalled for many years..

Solar heat plays a pivotal role in the functioning of greenhouses, serving as a primary energy source that influences the internal climate crucial for plant growth. The absorption of solar radiation by the greenhouse covering material initiates a complex process of heat transfer, involving conduction, convection, and radiation. This solar energy, once absorbed, contributes to elevating the temperature within the greenhouse, creating a favorable environment for plants. A fundamental understanding of solar heat dynamics is essential for optimizing greenhouse design and operational efficiency.

Greenhouses have become an essential part of modern agriculture as they offer controlled environments for plant growth, research, and horticultural practices. This chapter discusses the various applications of greenhouses, which include extending growing seasons, improving crop yields, supporting botanical research, and producing ornamental plants. Additionally, it emphasizes the importance of repair and maintenance in greenhouse operations. Understanding the repair and maintenance protocols is crucial to ensure the sustained functionality of heating systems, water management, and structural components.
