India is bestowed with huge production of fruits, vegetables, cereals, millets, sugarcane along with meat production, milk production, fish production and poultry. Despite such a huge production in India, owing to perishable nature of these produce around 25-30 percent of the produce is being lost as post harvest loss. The one important reason for this may be the production of the crops are season specific and during the peak season the production is more while demand for consumption is less. It may be possible to cut down these losses to great extent, if these produces may be transported from the produces states to those who are not producing due to agro-climatic reasons. So for making transportation of the perishable a successful venture in decreasing post harvest loss, there must be proper cool chain management facilities both at producing site as well as marketing place. The aim of the cool chain management must be to keep the produce in saleable condition during entire storage periods. Some products are stored for short period whereas fresh fruits, vegetables require cold storage. Foods before keeping into the storage room need some pre-storage treatments for better results.

A canal of approximate discharge of less than 80 cumecs (3000 cusecs) discharge may be called a medium or low capacity canal).

3.1 Mehboob Section

A Mehboob Section is only a modification of best trapezoidal section by making its complete bottom circular as shown in figure 3.1. Also see figure 1.6 and para 1.7. That is why these canals are also known as canals of zero bed width, or trapezoidal canals with curved bottom, or cup shaped canals.

But these cannot be called as triangular canals with curves, as often spoken. In fact it is a truncated triangle circumscribing the semi circle. Trapezium is also a truncated triangle circum scribing a circle.

More accurately it can be said as a combination of semi circular and best trapezoidal section so as to take full advantage of their hydraulic efficiency and practicability.

This is such a beautiful section that the designer can never commit a mistake, even if he wants to commit a mistake. The dimensions are so geometrically fixed that no one can play with any dimension.

The value of this section was realised for the first time by Er S I Mehboob (1943) in his Punjab Irrigation Branch Paper No.260" Lining of Canals". There after this canal section became well known as Mehboob Section after his name. He also stated that the most economical section i.e. the maximum area for the minimum perimeter is when the centre of the arc is at the full supply line of the section. This is also evident in figure 1.6. This is also the condition for all best hydraulic sections. This section is also useful to a higher silt carrying capacity than a wide shallow one..

Communication professionals often reference the Seven Principles of Communication, which, despite not being standardized, provide valuable insights for the Communication Competency within the Microsoft 365 Maturity Model. These principles can be particularly useful for those outside the communication field when developing communication strategies, conducting maturity assessments, or selecting appropriate technologies.

Principles of Effective Communication

1. Effectiveness: Communication must have a clear and purposeful objective. To achieve this, messages should be concise, consistent in tone and content, and engaging. Short, impactful statements often work better than lengthy prose. Visual aids such as diagrams and images enhance clarity and user experience (UX). Each message should culminate in a logical conclusion and a call to action. Effective communication also requires distinguishing between active and passive approaches, emphasizing important notifications while managing their frequency to avoid overuse. Inclusivity is crucial; approximately 10% of the population experiences dyslexia, and generational preferences for different media types (text, audio, video) must be considered. Alternative communication formats should be used to ensure messages are both effective and inclusive.

2. Comprehensiveness: Messages should be thorough and complete, leaving no ambiguity about the information provided. Recipients should have all necessary details to act promptly without confusion or loss of productivity. When communication cannot be completed in a single message, it should indicate when and how additional information will follow. Providing links to supporting materials is recommended.

3. Clarity: Clarity is essential for ensuring the message's purpose is understood by the receiver as intended by the sender. Messages should avoid causing confusion within the team. The format, goal, and language should be clear, and key points should be highlighted using short sentences, the active voice, and bullet points. Readability tools, spell checkers, and grammar checkers are valuable for verifying written communications before publication. Peer reviews or AI-assisted reviews can further enhance clarity.

4. Attention and Style: Effective communication captures the receiver's attention. Given the diversity in behavior, attention, and emotions, messages may need to be tailored for different roles and grades. Senior staff should exemplify the communicated messages, using appropriate messaging tools and processes. While formal communication is standard for conveying important information, informal communication can sometimes be more effective for gauging reactions and fostering engagement. Both communication styles should align with the organization’s ethos—typically positive, honest, respectful, open, and polite. AI tools can be used to check for the desired sentiment and style before publishing important communications.

5. Coherency: Communication often spans multiple tools and formats over time. It is essential to maintain a logical, well-planned, and consistent approach. Messages should connect with the main topic and reflect the company’s values, principles, and mission. Consistency with organizational policies, plans, and objectives is crucial to avoid conflicting messages.

6. Timeliness and Urgency: Communication should be timely and appropriately impactful, ensuring that messages are understood and actionable. It is important to distinguish between urgent and important information and to convey the timeframe for required actions. Confidence in message delivery timing is essential, and mechanisms for retrieving past communications should be implemented.

7. Importance of Feedback: Feedback is vital to confirm the effectiveness of communication, address questions, and clarify actions. Compliance requirements or monitoring functions may necessitate feedback or read receipts.

Introduction

Rice is the world’s most important staple crop and is a primary source of energy and nutrition for about half of the world’s population. So it is the most important cereal crop with respect to food security of common people. Due to increasing world population and shrinkage of farm land holdings there is an urgent need to increase the grain productivity. Therefore, increasing grain yield has become the primary objective in many rice-breeding programs. India is the second highest rice producer (about 120 million ton/year) in the world and able to meet the demand of rice for the entire Indian population. But along with yield improvement of rice, quality has now become a foremost consideration for rice consumers and millers. Quality is defined as “the totality of features and characteristics of a product or service that bears its ability to satisfy stated or implied needs” (International Standard Organization (ISO) 8402 1986). The concept of grain quality covers many physico-chemical properties such as grain shape and size, milling and cooking properties, amylose content, stickiness, chalkiness, texture, colour, gelatinization characters and various nutritional properties. Thus, rice grain quality generally includes five main classes i.e. (i) milling quality, (ii) physical quality, (iii) cooking and eating quality (iv) sensory quality and (v) nutritional quality. Grain quality and its assessment are very important to consumers, millers and rice breeders who are engaged in varietal improvement programme, related to new features such as high nutritional quality, high yield potential, highly resistant to abiotic or biotic stresses, higher water use efficiency etc.

5.1 Introduction

Out of the many climatic events that influence the earth’s environmental fabric, drought is perhaps the one that is most linked with desertification. Drought is a natural hazard originating from a deficiency of precipitation that results in a water shortage for some activities or some groups and is often associated with other climatic factors (such as high temperatures, high winds and low relative humidity) that can aggravate the severity of the event. Drought differs from aridity in that the latter is restricted to low rainfall regions and is a permanent feature of the climate. Drought occurrences are common in virtually all climatic regimes.

Widespread and severe drought conditions in Asia, Latin America and the Caribbean in 2000 have raised serious concerns about the continuing vulnerability of the world community to extended periods of droughts and water shortages. In 2000, major droughts affected much of south-eastern Europe, the Middle East, and the area through central Asia to northern China. Especially hard hit was Afghanistan, Bulgaria, Iraq and the Islamic Republic of Iran and parts of China. In North America, months of above-average temperature coincided with below-normal precipitation through northern Mexico and much of the southern and western regions of the USA, leading to one of the worst wildfires in the past 50 years.

By August 2001, much of Western Asia, Central Asia, and the Middle East was suffering the third year of a continuing drought that severely reduced many countries’ crop yields. The countries most affected were Afghanistan, India, Islamic Republic of Iran, Pakistan, and Tajikistan.

Introduction

Climate plays a crucial role in shaping the agricultural landscape of a region, and the changing climatic conditions pose a significant threat to global food security. In developing countries in Asia and Africa, the primary challenges to realizing optimal crop yields are declining soil fertility, particularly soil organic carbon and drought. The unchecked emission of greenhouse gases is expected to lead to a considerable rise in the average global temperature by 6°C in the next century, primarily driven by activities such as fossil burning and urbanization. Over the past centuries, there has been a noticeable increase in the concentration of CO2 and CH4 , with up to a 35% expected rise in nitrous oxide due to the improper use of nitrogenous fertilizers. Climate models predict a substantial impact on agricultural productivity in the 21st century, with rising temperatures and more frequent extreme weather events (NASA, 2022). To maintain agricultural productivity, it is imperative to understand the effects of increasing temperatures, shifting precipitation patterns, and rising CO2 levels on soil health. It is noteworthy that climate is one of the key factors influencing soil formation, alongside four other factors. Temperature and precipitation directly affect soil formation by providing the necessary conditions for weathering and biomass production. The sum of active temperature and precipitation evaporation ratio are critical parameters that determine energy consumption for soil formation, water balances in soil, organic-mineral interactions, and the transformation processes within the soil. However, human activities such as population growth, deforestation, disruption of marine ecosystems, and the greenhouse effect contribute to climate change, leading to denudation, depletion of soil organic matter, destruction of soil structure, erosion, and desertification, ultimately causing a decline in soil health and environmental degradation (IMD, 2021). Despite being a gradual process, climate change, characterized by small, long-term changes in temperature and precipitation, significantly influences various soil processes, particularly those related to soil fertility. The anticipated effects of climate change on soils primarily involve alterations in soil moisture conditions, increased soil temperature, and elevated CO2 levels. Understanding the consequences of climate change on soil health is crucial, as it has far-reaching impacts on agriculture, biodiversity, carbon cycling, and ecosystem resilience in the face of an evolving climate (Nunez et al., 2019).

Introduction

Seafood provides about 25% of the global intake of animal protein and fetches a huge economy for developing nations. Many challenges concerning food safety and quality exist due to globalization and liberalization of the global f ish trade. International food safety regulatory bodies such as WTO and CAC through SPS and TBT Agreements work on ensuring food safety and quality. Adoption of risk-based analysis and implementation of the HACCP system are encouraged to maintain high seafood safety standards. International regulatory bodies set maximum residual limits for various environmental pollutants and contaminants to ensure consumer safety. Consumer education programs play important role to enhance awareness and improve transparency in the seafood supply chain. Internationally traded seafood products therefore need to meet the standards prescribed for food safety and quality requirements. In case of non-conformance, they could be detained, rejected and destroyed.

The global demand on seafood quality and safety requirement and the complexities of seafood supply chain make difficulty to ensure authenticity and traceability of seaood products in the market. Most seafood is exported from the country where it is caught while part of it via. a third country. Seafood pass-through complex supply chains involving, capture/culture, transshipment, processing, packaging, wholesale, retailing, and consumer. The global trade of seafood has led to a significant concern associated with seafood fraud.

12.1. Seafood Fraud

Seafood fraud is the practice of providing misleading information to the consumers about their product for financial gain. There are nine types of seafood fraud, which include species substitution, fishery substitution, IUU substitution, species adulteration, chain of custody abuse, catch method fraud, undeclared product extension, modern day slavery, and animal welfare

Introduction

Importance of basic statistics in everyday life cannot be stressed enough. Inclusion of basic statistics in high school curriculum is uncommon but proves highly beneficial to supplement certain careers in future. This field may be the most widely used of all and most people don’t even know they are using it. Many of today’s brightest business minds use this study to create charts and graph that allow them to stress a certain aspect of the business they are dealing with. Market research agencies, News rooms, marketing divisions of large corporations, NGOs, accounting firms etc. are full of people who specialize in basic statistics.

Statistics is concerned with the describing, interpreting and analyzing data. It is, therefore, an essential element in any improvement process. Statistics is often categorized into descriptive and inferential statistics. It uses analytical methods which provide the math to model and predict variation. It uses graphical methods to help making numbers visible for communication purposes.

Descriptive Statistics

• Descriptive statistics summarizes or describes characteristics of a data set.

• They help to make sense of large numbers of individual responses, to communicate the essence of those responses to others

• Helps exploring and making conclusions about the data in order to make rational decisions.

• Includes calculating things such as the average of the data, its spread and the shape it produces.

• Are displayed as tables, charts, percentages, frequency, distributions and reported as measures of central tendency

• Determine if the sample is normally distributed (bell curve) as most statistical tests require the sample to have normal distribution

• Determine if the sample can be compared to the larger population

Difference between Descriptive and Inferential Statistics

Nowadays, statistics is playing a major role in the field of research; that helps in the collection, analysis and presentation of data in a measurable form. It is quite hard to identify, whether the research relies on descriptive statistics or inferential statistics, as people usually, lacks knowledge about these two branches of statistics. As the name suggests, descriptive statistics is one which describes the population. On the other end, Inferential statistics is used to make the generalisation about the population based on the samples.

Introduction

With the growing population of the country and the increasing requirements for f ish protein, the need for sustainable development of the post-harvest fisheries sector is now felt much more than ever before. Fish and fishery products serve as a part of a balanced diet because fish is known to be an excellent source of proteins, essential fatty acids, vitamin D, vitamin B12, and many useful trace elements such as selenium and iodine. Especially, Omega-3(n-3) fatty acids such as DHA and EPA are plenty in fish, contribute significantly for the functioning of vital organs viz heart, brain, immune and reproductive systems. Over the years the demand for fish is on the rise all over the world due to such health benefits.

The harvest and post-harvest handling, processing and distribution of fish provide livelihood for millions of people as well as provide valuable foreign exchange earnings. India’s scale, its large and growing population and its over 500 million strong labour force pose a daunting challenge to job creation. The rising population in India is also accompanied by the rise of unemployment in all the sectors. Indian economy is also being hampered due to this problem. Meanwhile, it is also not possible for any government to create job for all. Probably, the solution of this burning problem is to encourage and support entrepreneurship.

Entrepreneurship is a dynamic process of creating incremental wealth and impact, and entrepreneurs are people that notice opportunities and take the initiative to mobilize resources to make new goods and services. Over the years, entrepreneurship has played a vital role in shaping the Indian economy, and it is set to play an even more important role in the future. Startups and small businesses are often more nimble and able to adapt to changing market conditions, which allows them to bring new products and services to market more quickly. The government has introduced a number of programs and initiatives aimed at promoting entrepreneurship, such as the Start-Up India program and the Pradhan Mantri Mudra Yojana.

I always feel I am very lucky and got a chance to live in this beautiful God gifted planet by blessings of God and whatever God fixed for me I am trying my best to do so that I can fulfil my journey and reach to my destine and finally will back to the same place where I came. My father was a Botany Lecturer, he retired from his job in the year 2009 and my Mother is a house wife. I have one brother and two sisters. All are married now and me my misses, my son (Calyx) staying at my native village with my parents after I came back from Indian Agricultural research Institute and my brother and two sisters are staying at Bhubaneswar. I have a very small family staying happily at my village. I have completed my schooling at my village school which is just 1 km away from my home. My village Garh Guatira is belongs to Nimapara block of Puri district of Odissha and it is just 50 km away from Bhubaneswar. My village is very small which is surrounded by agriculture field specially 90% area is under rice cultivation. So I spent my childhood with my natural village climate and maximum time I spent in the village surroundings with its natural activities. I got first class in Botany (Hons) with distinction from the Nimapara college and it was one of the best moments for me, at least one step I moved towards my destination.

• The thorax is the organ of locomotion due to articulation of wings and legs and is connected with the by neck or cervix.

• Thoracic segments are made up of three sclerites namely, dorsal body plate tergum or nota, ventral body plate sternum and lateral plate pleuron.

• Second and middle tagma which is three segmented, namely prothorax, mesothorax and metathorax. Meso and metathorax which bear wings are called as Pterothorax.

• In the apterygote insects the three thoracic segments are similar in size and structure. In the pterygote insects the thorax is highly modified.

• The prothorax is quite large and is somewhat independent of the other segments. The large shield that covers the dorsal and lateral sides of the prothorax is the pronotum.

• The pronotum is the dorsal sclerite of the prothorax, which can be highly modified in various orders such as the Hemiptera, Blattaria, and Coleoptera. E.g undivided and Saddle shaped in grass hopper, Shield like in cockroach.

• Cockroaches have pronotums that extend forward over the head.

• Scarab beetles and other beetles may also have unusual pronotums.

• Treehoppers have some of the most bizarre pronotums of all insects.

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).

Introduction

Walnut (Juglans regia L.) is an important temperate nut crop grown in various parts of the world. It belongs to the family Juglandaceae and is commonly known as English walnut, Persian walnut, or common walnut. It has a chromosome number of 2n=32 (Kalia et al., 2016). Walnuts are a rich source of omega-3 fatty acids (Husain et al., 2013). The walnut fruit is a drupe that contains a nut surrounded by a hard shell. The nut is enclosed in a fleshy green or brownish-yellow hull, which splits open when the fruit is ripe. Walnut is an important nut crop due to its high nutritional value and medicinal properties. The kernel of the walnut is rich in protein, fat, and minerals such as calcium, phosphorus, and magnesium. It also contains vitamins B1, B2, and E. In addition to being used as food, walnut has been used in traditional medicine for the treatment of various ailments such as diabetes, cardiovascular diseases, and cancer (Liu et al., 2017). Walnut oil is rich in linoleic acid and is used in the production of cosmetics and soap. The leaves and bark of the tree are used in traditional medicine to treat various ailments such as diabetes, fever, and inflammation.

Different Classes of Seeds

1. Nucleus Seed: It is handful of seed maintained by concerned breeder for further multiplication. The nucleus seed will have all the characters that the breeder has placed in it and it is of highest genetic purity. The quantity of nucleus seed is in kilograms.

2. Breeder Seed (BS): Breeder seed is a seed or vegetative propagating material directly controlled by the originating or sponsoring plant breeder of the breeding programme or institution and or seed whose production is personally supervised by a qualified plant breeder and which provides the source for the initial and recurring increase of foundation seed. Breeder seed is exempted from certification. However, the breeder seed crop is being inspected at appropriate stages by a Monitoring Team consisting of breeder, representative of NSC and representative of Seed Certification Agency. The breeder seed lots are affixed with Golden Yellow tags. The genetic purity of breeder seed crop should be maintained at 100 per cent.

8.1. Introduction

The term canning refers to a process which involves heating food stuff in hermetically sealed containers for a specific time at specific temperature to eliminate microbial pathogens that endanger public health and micro-organisms as well as enzymes that deteriorate food during storage. The canning of fruits and vegetables is canned out in the season when they are available in plenty. The canned products are then sold in the off season for getting better returns and to assure availability of fruits and vegetables throughout the year at reasonable prices.

8.2. History of canning

Important historical developments in canning are as under:

• The credit for invention of canning goes to Nicholas Appert, a French confectioner who was awarded a prize in 1809 by the French government for developing new method of heat preservation of food in sealed container and after whose name the process of canning is known as Appertization.

• In year 1810, Appert published the first book on canning entitled The Art of Preserving Animal and vegetable substances for many years which is the first known work on canning.

• The work of Appert consists of packing food in glass bottles, closing with corks and heating the container in boiling water for several minutes depending upon type of food.

15.1. Introduction

Freezing is one of the oldest and most widely used methods of food preservation, which allows preservation of taste, texture, and nutritional quality in foods better than any other method. It is a process of bringing down the temperature of food below its freezing point and the frozen storage generally refers at temperature below -18oC.

15.2. Theory of freezing

The freezing process is a combination of the beneficial effects of low temperatures at which micro-organisms cannot grow, chemical reactions are reduced, and cellular metabolic reactions are delayed. Freezing is generally referred to as a unit operation in which the temperature of food is reduced below freezing point and a proportion of water undergoes a change in state to form ice-crystals. Immobilisation of water to ice and the resulting concentration of dissolved solutes in unfrozen water cause lowering of water activity of the food. Thus reduction in water activity and use of low temperature coupled with some pre- treatments like blanching is the basis for food preservation by freezing. Fruits such as strawberries, oranges, raspberries, black currants and vegetables like green pea, green beans, sweet corn, spinach, sprouts and potatoes are examples of commercially frozen products.

The recent social, political, and economic challenges worldwide necessitate the adoption of new strategies by governments and development agencies to enhance people's livelihoods. These challenges underscore the importance of understanding and appreciating the growing significance of livelihood issues, particularly sustainable livelihood mechanisms. Addressing issues such as poverty, hunger, food security, gender equality, and economic growth—which are central to the Sustainable Development Goals (SDG 17)—requires a comprehensive understanding of the complex nature of livelihood challenges, livelihood diversification, and sustainable livelihood strategies.

Governments and non-governmental organizations, especially in developing nations, are under increasing pressure to develop coordinated strategies and interventions aimed at livelihood diversification. These efforts are crucial to sustainably improve the livelihoods of the poor, disadvantaged, vulnerable, and excluded populations.

1.1. Introduction

Wildlife management often requires interventions to safely handle and transport animals. Chemical restraint, also known as immobilization or tranquilization, is a technique widely used to facilitate these processes (Hernandez, 2014). It involves the administration of drugs to temporarily immobilize wild animals, allowing for various procedures such as veterinary medical examinations, tagging, relocation, or rehabilitation. This chapter provides an overview of the principles, methods, drugs, and considerations involved in the chemical restraint of wild animals.

It has been often stated that the most important techniques required by the zoo veterinarian are those used in the capture and restraint of the patient. These techniques have developed into a highly technical science (Clarke et al., 2014). In the early days of zoos, the only practical method was to manually catch and hold the patient. Modern techniques, however, permit a veterinarian to shoot a CO2 powered gun, which discharges a projectile syringe at an animal resulting in complete immobilization of the animal (Jacques et al., 2009). This is accomplished without any physical contact between the patient and his captors.

Globally, organic oilseeds constitute an important element in organic production. Their products are important feedstuffs (oilcake) and also relevant for human consumption (soya products, oils), and demand for these is continually growing. Almost half of the global organic oilseed area is occupied by soybeans, and another almost 20% is for sunflower seeds and sesame. Rape and turnip rape constitute about 6% of the organic oilseed area. Oilseeds are of pivotal significance in the Indian agricultural economy supporting income of millions of farmers practicing mainly rainfed cultivation. Nine annual oilseed crops are cultivated in India that includes groundnut, rapeseed-mustard, soybean, sunflower, sesame, niger and safflower that are edible and non-edible oilseed crops include castor and linseed. Organic agriculture is one among the broad spectrum of production methods that are supportive of the environment. The principal method of organic farming includes crop rotation, green manures and composts, biological pest control and reduced tillage. The performance of annual edible oilseed crops and development of package in relation to organic management for sustainable agriculture are discussed in this chapter.

1. Introduction

In India, both annual and perennial edible oilseed crops are cultivated. Annual edible oilseed crops include groundnut, rapeseed-mustard, soybean, sunflower, sesame, niger and safflower. India, the 4th largest vegetable oil economy in the world, stands first in the production of castor, sesame, safflower, and niger oils, whereas second in groundnut, third in rapeseed mustard, fourth in linseed and fifth in soybean oil. About 14 million farmers are engaged in oilseeds production and another million in their processing. Whereas, the perennial edible oil seed crops include oil palm and coconut. Edible oils are also produced domestically from secondary sources such as rice bran, cotton seed, corn, and other tree-borne oilseeds (TBOs), besides some minor oil producing species of forest origin.

Organic food sales increased steadily from the late 20th century. Greater environmental awareness, coupled with concerns over the health impacts of pesticide residues and consumption of genetically modified (GMO) crops, fostered the growth of the organic sector. Realizing the benefits of organic food, especially after COVID-19, consumers are also demanding organically grown food and fiber and are willing to pay premium price. But to tap the market, there is an inevitable need for certification. Recently launched Food Safety and Standards (Organic Food) Regulation, 2017 mandates that all food products sold as organic must be certified and comply the basic requirements of the Act. The organic food offered or promoted for sale shall also comply with all the applicable provisions of either National Programme for Organic Production (NPOP) or Participatory Guarantee System for India (PGS India). Organic certification is a process certification. The requirement to confirm that the product is organic include labelling on the package and traceability for both domestic and export needs to be understood. For import and export of organic produce, transaction certificate issued by an Accredited Certification Body is required. These requirements are essential for fresh and processed food items. In this chapter, we tried to eloborate the process and procedures for organic certification.

Fruit ripening is a phenomena during which horticulture produce undergoes a series of complex physical and biochemical changes initiated through a series of hormones (Ethylene, auxin, abscisic acid (ABA), gibberellins, jasmonic acid, etc.) to attain maximum physiological maturity and favourable organoleptic properties. These changes lead to alterations in colour, texture, aroma, flavour and nutrient composition. In a nut shell, ripening involves increase in pulp to peel ratio, solubilisation of pectic substances, degradation of complex carbohydrates, organic acids and chlorophyll, accumulation sugars, flavour volatiles, polyphenolic compounds and pigments (carotenoids, xanthophylls and anthocynanins). The extent of these changes guide harvesting, readiness for processing and consumption decisions, with physic-chemical alterations serving as indicators of optimum ripeness. Respiration rate, ethylene and ABA are key regulators of fruit ripening in climacteric and non-climacteric fruits, respectively. In climacteric fruits, ABA interacts with ethylene, influencing the synthesis of ethylene itself. Although there is ample documentation on the involvement of hormones in fruit development and ripening, our understanding of the functions of various hormones throughout growth, maturation, and specific ripening processes remains incomplete.

Waste is defined as anything that doesn’t add value to their operations. To the average person, waste is simply stuff that’s unwanted or useless. But from a scientific perspective, there’s really no such thing as waste. Nearly all the things we throw away can be transformed or processed in ways that make them useful again.

Waste comes in various forms, ranging from household trash to industrial byproducts. These include domestic waste, factory waste, e-waste, construction waste, agricultural waste, and more. We can categorize waste into different types:

Solid waste: This includes organic materials like vegetable and kitchen waste, as well as general household waste.

E-waste: Discarded electronic devices such as computers, TVs, and music systems fall into this category.

Liquid waste: This comprises water used in various industries, as well as waste from tanneries, distilleries, and thermal power plants.

Plastic waste: Items like plastic bags, bottles, and containers make up this category.

Charts and graphs are essential tools for visualizing data and presenting information in a clear and comprehensible manner. They transform raw data into visual representations, making complex data easier to understand, analyze, and communicate. Various types of charts and graphs serve different purposes and are chosen based on the nature of the data and the message intended to be conveyed.

Historical Background and Evolution

The use of charts and graphs dates back centuries, evolving alongside advancements in mathematics, statistics, and technology.

Early Developments

Ancient Civilizations: Early forms of data visualization can be traced back to ancient civilizations. For example, Egyptian hieroglyphics and Babylonian cuneiform tablets included basic graphical representations of information.

William Playfair (1759-1823): Often considered the father of statistical graphics, Playfair introduced several fundamental chart types, including the bar chart, line chart, pie chart, and circle chart, in his works such as “The Commercial and Political Atlas” (1786) and “The Statistical Breviary” (1801).

3.1 Introduction

In developing and in semi-developed countries, rural-urban migration is driven by the uneven distribution of employment, income-opportunities etc. (Skeldon, 1990). Rapid population growth, especially in rural areas, provides an important demographic backdrop to these rural-urban population shifts. Given the growing and well-known difficulties that are faced by the overall Indian population in f inding productive employment, it is important to study the characteristics of labors that migrate from rural-urban areas. Under this backdrop, attempts have been made in this study to examine the nature, pattern and determinants of rural urban migration and the spread of urban informal sector and the likely impact of rural-urban migration on agricultural productivity and efficiency.

The foundation of modern insect classification was laid by Brauer in 1885. According to Brauer insects were classified as Subclass: Apterygogenea (pterous) and Pterygogenea (winged) based on:

• Presence or absence of wings.

• Mouthparts.

• Metamorphosis.

• Number of Malpighian tubules.

• The nature of wings.

• Thoracic segments etc.

The earliest classification of insects was based on habits and habitats and on certain gross anatomical features that define the general aspects of different kinds. In classifying insects, not only anatomical characters but also facts pertaining to physiology, biology, distribution, ecology and sometime cytology of the species is taken into consideration.

Introduction

The rapid growth and socio-economic upliftment of a developing country are directly related to the intensity of industrial growth of that country (Bastian et al., 2019; Kniivila, n.d). The emergence of new enterprises is the main source of a healthy and growing industrial ecosystem. They represent 99% of businesses in developing countries and account for two-thirds of employment creation (Secretary-General and UNCTAD, 2022). Enterprises hence create employment, drive inclusive growth, promote innovation, and improve socio cultural conditions along with addressing sustainable development goals- No poverty(SDG-1), Industry, innovation and infrastructure(SDG-9), Reduce inequality(SDG-10)of the UN’s 2030 agenda (Forbes, 2022; Secretary-General and UNCTAD, 2022). Their innovative outputs in the form of goods and services, address local as well as global requirements of the customer market and bring them on the path of sustainability (Szopik-Depczynska et al.,2018; Rivera et al.,2020). The entrepreneurs have a long vision of success, engaging their primary activities with No poverty (SDG-1), Zero hunger(SDG-2), Gender equality(SDGs-5), Decent work and economic growth(SDG-8), Industry, innovation and infrastructure(SDG-9), Reduce inequality(SDG-10), Responsible consumption and production(SDG-12), Climate action(SDG-13), Partnership for goals(SDG-17) and addressing challenges of society and the environment in return for optimal economic profit (Alagpuria,2021; Lammers et al.,2022; Secretary-General and UNCTAD,2022; Vig,2021; Del-Aguila Arcentales et al.,2022; Sadiq et al.,2022).

For effective and economic control of pests, besides selection of appropriate plant protection chemicals, application of the chemicals at the most vulnerable growth stage of the pests and use of chemicals at the correct dosage, selection of proper plant protection appliances to carry out the operation is also of vital importance, so as to ensure uniform application of the chemicals.

Plant protection chemicals are mostly used as sprays and dusts using sprayers and dusters respectively. However, in most of the cases spraying is preferred to dusting. Different types of sprayers and dusters are being used for these operations and in both, there are manually operated as well as power operated equipments and in sprayers there are both hydraulic and pneumatic types of sprayers.

The nature of the pesticide formulations to be used and the purpose for which they are used also determine the type of equipment to be used. Dusters are used for dusting insecticidal dust formulations. Sprayers are used for spraying insecticidal liquid formulations. Granular applicators are used to apply granular formulations. Fumigators are used to apply fumigants to fumigate godowns, warehouses, rat holes etc. Soil injectors are used to inject pesticides at a particular depth of soil under pressure. Flame throwers are used to throw f lames at specified targets.

Introdction

Fruits are an important supplement to the human diet, as they provide minerals, vitamins and fiber required for maintaining good health. Fruits are also rich in phytochemicals (7, xanthophylls, polyphenols, flavonoids, phenolic acids, organic acids etc.) which possess good antioxidant properties. India’s diverse climatic conditions ensure availability of almost all the varieties of fresh fruits and vegetables. According to FAO (2021), the country ranks first in the production of bananas (26.45%), mangoes (including mangosteens and guavas) (43.80%) and papayas (39.30%). The scenario of horticulture crops in India has become very encouraging. The percentage share of horticulture output in agriculture has become 33 per cent (Anonymous 2021). India has witnessed increase in horticulture production over the last few years. Significant progress has been made in area expansion resulting in higher production. Over the last decade, the area under horticulture grew by 2.1 per cent per annum and annual production increased by 3.9 per cent. During 2020-21, the production of horticulture crops was 334.60 million tonnes from an area of 27.74 million hectares. The production of fruits has increased from 76.42 million tonnes in 2011-12 to 108.34 million tonnes in 2022-23 (Agricultural Statistics at a Glance 2022). The area under cultivation of fruits stood at 7.05 million hectares. The total production of fruits in the year 2020-21 was highest in case of Andhra Pradesh (17.70 million tonnes) followed by Maharashtra (11.73 million tonnes) and Uttar Pradesh (11.23 million tonnes) (Anonymous 2021). India now is the second largest producer of vegetables and fruits in the world. The country ranks at first position in the production of banana, mango, lime and lemon, papaya and okra. The area and production of fruits in India is presented in Table 1. The fruits namely banana, mango, citrus, papaya, guava, grapes, apple, pineapple and sapota account for more than 85 per cent of the total production of fruits. The other fruits which are produced in India are almond, walnut, jackfruit, bael, ber, custard apple, kiwi, passion fruit, peach, pear, plum, strawberry etc.

I. Rock Phosphate

Rock phosphate is natural source of phosphorus. It occurs as natural deposits of rock in Morocco, U.S.A., Egypt, Poland, Russia, Tunisia, Algeria, Brazil, Nauru and some Islands in the Pacific and the Indian ocean. It contains 20 to 35 percent phosphoric acid (P2 O5 ) but this phosphorus is in insoluble form. In India, some of rock phosphates occur in Udaipur and Jaisalmer districts (Rajasthan), Purulia (West Bengal), Singhbhum (Zharkhand) and Mussorie (Uttrakhand). Most of these phosphates are classified as low grade phosphate since its phosphoric acid content is less than 20-25%. The total reserve of low grade rock phosphate is estimated to be around 165 million tonnes of which nearly 70 million are reported to occur in Rajasthan. The other economically viable deposits are in Mussorie (Uttarakhand), Jhabua district (Madhya Pradesh), Singhbhum (Zharkhand) Kasipatnam (Andhra Pradesh) and Purulia district (West Bengal). Rock phosphate is the basic raw material for manufacture of superphosphate and other kind of phosphatic fertilizers. It is reported above that India has mostly low grade rock phosphate. Hence India has to spent huge amounts of foreign exchange to import high grade rock phosphate containing around 32-35%, P2 O5 for manufacture of phosphatic fertilizers.

Frankia is potent nitrogenous biofertilizer for forest trees since it establishes symbiotic association with non-leguminous plants. Nitrogen fixing non leguminous trees thrive in temperate condition. The species belong to Casuarinaceae are an exception and grow successfully in tropical areas. Alnus for temperate regions and the genus Casuarina for tropical and sub-tropical regions stand out examples of the benefits they provide to ecosystem by the way of nitrogen fixation. They have an excellent potential to adapt themselves to grow under diverse geographical and environmental conditions providing enough fuel, fodder, pulp and timber. The microsymbiont within these root nodules of non-leguminous plants has been identified and designated as Frankia (Becking, 1970).

Historical Developments

First of all Boussingault, a French farmer during 1838 drew attention that non-legumes were capable of fixing atmospheric nitrogen. The roots of Alnus were described as warty brownish biomass as large as man’s fist (Woronin, 1866). Frank and coworkers (1887a, b, 1891) studied the nodulated nitrogen f ixing trees regardless of whether they were leguminous or non-leguminous (actinorhizal). Frank believed that the bacteroids were protein deposits but subsequently he named the causative organism as Frankia subtilis. Moller (1885, 1890) reported the causative organism in the nodules as plasmodia and Frank also revised his opinion and pointed out that the causative organism was a fungus. Such conflicting results were due to imperfect techniques to differentiate between vesicles and sporangia. Later the organism was renamed as Frankia bruchorstii to honour Frank and his coworker, Brunchorst (Moller, 1890).

Introduction

Agriculture has always been linked with prosperity, man power and the ability to feed and raise human population. In earlier times, humans as man power were deployed on the fields to do all the necessary operations to cultivate the crops, but during the industrial revolution, with development of different farm machines the uses of human labor on the fields were drastically decreased. Further, with advancement of technologies and more availability of computers, Artificial Technology (AI) has been gaining momentum in recent years.

AI has the potential to transform the agricultural sector through cost reduction and increased crop yields, and minimizing environmental impacts. AI can help farmers better manage their land, improve crop quality, and increase their productivity In addition, AI can be used to monitor and analyze the health of crops, livestocks, and soils to identify issues and assist in their resolution. The primary idea of using artificial intelligence in agriculture is due its adaptability, superiority, and cost-viability. The customary techniques that were utilized by the farmers were not adequate enough to satisfy their necessities. (Khan et al. 2022) With the right implementation and technology, AI can be an invaluable tool to help farmers increase their efficiency and profitability. In today’s rapidly evolving world, where the demand for food continues to escalate amidst concerns over environmental sustainability and resource scarcity, Artificial intelligence (AI) has become a transformative force in agriculture, from optimizing crop production and resource management to enhancing decision-making processes. Globally, AI is changing how we approach farming techniques.

The term entrepreneur is derived from the French word entreprendre, which translates to “to undertake. “In the context of business, this refers to the initiation of a business. According to the Merriam-Webster dictionary, an entrepreneur is defined as an individual who organizes, directs, and takes risks in a business or enterprise. An entrepreneur can be described as “a person who establishes, organizes, and directs any enterprise, particularly a business, typically involving significant initiative and risk. “ Peter F. Drucker (1985) characterizes an entrepreneur as a person who continuously seeks change, responds to it, and leverages it as an opportunity. Innovation serves as a unique tool for entrepreneurs, enabling them to perceive change as an opportunity for launching another business or service. An entrepreneur is often regarded as an innovator – a creator of new ideas and business processes. Essential leadership skills and effective team-building abilities are frequently considered crucial traits for successful entrepreneurs. Economist Robert Reich (2002) regards leadership, management skills, and team building as vital attributes of an entrepreneur. The realm of entrepreneurship is influenced by a variety of combinations of socio-economic, psychological, cultural, and additional factors, including caste/religion, family background, educational level, level of insight, professional experience, migration capabilities, entrepreneurial spirit, nature of the business, investment capacity, and ambition/moderation. Entrepreneurship is often defined as “the ability and desire to develop, organize, and manage business activities and associated risks for profit”.

Aquaculture is associated with the rearing, breeding, and harvesting of aquatic organisms in cages, tanks, ponds, or other simulated systems, and can be practiced in fresh water, brackish water, or marine water. The practice of cultivating aquatic species in a systematic manner dates back to before 1000 BC. Theories such as oxbow, catch-and-hold, concentration, and trap-and cropexplain how the transition from hunting to farming may have occurred along with the advancement of civilization. Along with rearing the aquatic species for nourishment, advanced techniques have led to the enhancement of economic value through the inclusion of pearl oyster farming. India is among the largest producers of fisheries and has become the world’s second largest producer of aquaculture fish. Globally, aquaculture diversity has reached a maximum value of 428 ± 11 species, of which 29 ± 1 will produce 80% of the global annual production. The total global aquaculture production has increased enormously, from 20 million tons in 1992 to more than 120 million tons in 2020. Fisheries and aquaculture have become essential foods providing commodities worldwide and an important means of nourishment for the poor. A temporal and geographical analysis of global aquaculture diversity reveals an original and hopefully enlightening vision of modern aquaculture and its perspectives.

Ruminant, major source of meat and milk for human consumption, whose digestive system has evolved in such a way that it provides an additional advantage of being non-competitive to human food chain. Global warming is real and rising with a pace threatening lives of all flora and fauna on earth. Methane produced by ruminant bacteria predominately by methanogen group of bacteria acting as hydrogen sink cause loss of dietary energy to the animal affecting its potential productivity as well as a major source of global warming. The use of plant secondary metabolites is preferred as a feed additive in ruminant diet to improve fatty acid production by reducing enteric methane. The study was carried out using 10% aqueous and ethanolic extract of Psidiumguajawa leaves powder, citrus fruit peel powder to assess in vitro rumen fermentation parameters. The in vitro trial was conducted by taking different concentrations @ 0.2 ml, 0.5ml, 1ml and 2 ml of plant extracts with substrate media containing rumen fluid. After 6 and 24 hours of incubation, pH, total gas production, ammonia- nitrogen, TVFA and total nitrogen were measured. Bacteroides and methanogenic bacterial profile was done by Real time PCR. The results revealed that the total gas production decreased in plant extract supplemented samples with respect to control. Total nitrogen production increased in aqueous P. guajawa and increase in TVFA was observed in all plant extract supplemented samples. Ammonia- nitrogen production does not vary significantly, indicating no change in NPN degradation due to supplementation of different plant extracts at different concentration. Total bacteroides expression were increased in rumen samples treated with P. guajawa and citrus peel powder, while a decrease in methanogenic bacterial expression was observed in plant extracts supplemented samples as compared to control indicating an improvement in rumen fermentation further enhancing productivity.

1. Use of banana pseudostem in fish pond to enhance productivity of f ish: Pseudostems of banana, after harvesting the bunch, are added to the pond by cutting longitudinally, which increases the pH and oxygenation of pond water. This practice increases the fish yield. As it involves low cost, it is being followed by 80% of the farmers in Bastar village of Balasore district in Odisha.

2. ITKs on Craft and Gear Making / Maintenance (Vipinkumar et al., 2013): The major ITKs of scientific rationale identified in the craft and gear making and maintenance were ‘Sardine oil smearing on craft wood for improving the durability’, ‘Smearing cashew kernel oil on craft wood for durability’. Similarly, the durability of cotton nets was believed to be improved by dipping in banpu bark decoction. In the same way, beating nets with thalampu plant for ensuring strength was another one identified in craft and gear maintenance. The scientific validity assessment indicated that the boats of about 6.5 ft size length and 4.5 ft width require 3.5 to 4 litres of oil of sardine. The oil coasts about Rs 70/- per litre. Three cosequitive coatings followed by natural drying under sun are required for good results. Cashew smearing: The boats of about 6.5 ft size length and 4.5 ft width require 3.5 to 4 litres of cashew nut oil and the oil costs about Rs 40 -50/- per litre. Here also three cosequitive coatings followed by natural drying under sun are required for good results. Smearing Cashew kernel oil on craft wood for durability in Karwar of Karnataka is shown in photograph 1. For improving durability of nets, dipping nets in banpu bark decoction was practiced. The thalambu beating is nowadays not practiced due to the non-availability of those items. Instead, fisherfolk use a powder available in the market especially in the net shops. 1 kg of the colour powder (red/ blue) is required for 1 kg of net. The advantage is that the wastage due to mud coating and dirt can be rectified to a great extent.

Millets are highly nutritious and play a significant role in many people’s diets around the world. They have traditionally been transformed into a range of products through fermentation and malting for centuries. In the era of sustainable development, we still lag in using millets as a primary source of nutrition even after knowing that they are rich in terms of nutrition and other essential elements as compared to cereals. Today we have lots of information regarding different millets; nutrition content, methods of preservation, fermentation, malting, its products etc. Foods made from millet are regarded as potential prebiotics because they can improve the availability or functionality of probiotics, which has major positive effects on health. Foods have been fermented in order to enhance their flavor, texture and palatability. Although fermentation can result in a variety of products, the most prevalent ones are ethanol, lactic acid, carbon dioxide and hydrogen gas (H2 ). Commercial applications for these materials include use in food, vitamins, medications and industrial chemicals. Additionally, fermentation increases the amount of protein present, improves the accessibility of carbohydrates and reduces antinutritional components like tannin and phytic acid. Even though it has some drawbacks, such as the potential for contamination with dangerous microbes, fermentation technology is proven to enhance the nutritional quality of food products. This chapter covers the millet fermentation technology’s effects on the nutritional composition of the millets, contemporary developments in fermented millet-based products and technological improvements examined in the millet fermentation technology.

Introduction
Agriculture is an age-old income generation activity in India. It plays a vital role in India’s economy. One in every two Indians relies on agriculture for livelihood. Over 58% of the rural households depend on agriculture as their principal means of livelihood. Over the period of time, the contribution of agriculture and allied sector in Gross Domestic Products (GDP) in India has declined to 14.4% in 2018- 19 from 51.8% in 1950-51. At current prices, the contributions of industry and services sector are 31.5%, and 54.1%, respectively as against the contributions of industry and services sector were 15.1% and 33.1%, respectively in 1950-51. This decline in share of agriculture and allied sector is result of the shift from traditional agricultural economy to industry and service sectors, this performance are very meagre if we consider the size of the employment in this sector. Presently, more than 50% of the total workforce of the country is employed in agricultural sector contributing to only 14.4% of GDP. With production of agriculture activity 26of $375.61 billion, India is 2nd larger producer of agriculture product in the world after China which has contribution of $991 billion in agriculture sector. GDP of industry sector is $560.97 billion and world rank is 6th. In services sector, India’s world rank is 8th and GDP is $1500 billion (FAENI, 2018- 19). Interestingly, contribution of agriculture sector in Indian economy is much higher (7.4%) than world’s average (6.4%), while contribution of industry and services sector is lower than world’s average (30% for industry sector and 63% for services sector).

The crop production has been found to make wide use of chemicals with hundreds of newly imported molecules. Unnecessary and excessive use of inorganic chemicals have led to an upsurge in the ecosystem and imbalance of nature. Natural enemies and bees get destroyed with chemical pesticides. Other side effects include resurgence of target pests and outbreak of secondary pests. Moreover, the residues of the pesticides in food products and environment have caused grave health issues. The contamination of pesticides into the fruits causes a quality decrease of the fruits, which is widely reported. The best available solution for sustainable agriculture can be the non-chemical organic/ natural farming that does not permit the usage of inorganic and synthetic chemicals for crop cultivation. Natural farming is the ecology-based production management system promoting and It provides biodiversity, biological cycles, and soil biological activity. The basic principles of organic/natural farming are materials and practices that enhance the ecological balance of natural systems that integrate parts of the farming system into the ecosystem. The first purpose of natural farming is to improve the health and productivity of interdependent communities of soil life, plants, animals, and people, that is termed as ‘one health concept’.
Natural farming is a system in which laws of nature are applied to agricultural practices. It has an advantage of natural biodiversity on every area of farmed resources; it also fosters the intricacy of living organisms, plant and animal alike, which would form each specific ecosystem to grow in harmony with food crops. Insects are indeed very mobile and well adapted to farm production systems as well as pest control tactics. Organic/natural farms focus on management, not eradication, of these insects. Thus, success in organic/natural farms depends on learning the biological, ecological, and behavioural information of the insects. The biological information as to what the insect needs to survive can be used to determine if insect pests can be deprived of some vital resource. Ecological information can be used to inform how the insect interacts with the environment and other species. shape an environment resistant to pests.

Introduction
Vegetable crops are highly susceptible to biotic stresses indicated by disease causing micro-organism (fungi, bacteria, virus and phytoplasma). Indiscriminate use of chemicals for the control of diseases, insect pest have
several disadvantages, particularly increased cost of cultivation, residual toxicity in food chain and development of resistance against pathogen. Management of diseases involves use of resistant varieties and integration of cultural and chemical control measures. Of the biotic stresses much of the breeding efforts have been directed towards developing resistance against diseases. In fact, breeding for resistance, has been one of the most important objective of vegetable breeder in the last half of the century. Genes that contribute to pathogen tolerance/resistance can be obtained from local germplasm resources, or through exotic lines, wild species or genera, or lines from other breedingprograms. In the biotechnological approaches for vegetable breeding also,  most of the achievement has been to generate transgenic plants resistance to disease. Often breeding for resistance has assumed greater importance in a number of vegetable crops.
Major Diseases of Tomato
Early blight: The casual organism is Alternaria solani. The symptoms appears as small, black spots with enlarged and concentric rings in a bull’s eye pattern in the center of the leaves. Tissue surrounding the spots may turn yellow. On fruits, dark brown concentric rings are seen that affects the market quality.

Introduction
Preservation by using common salt, spices and vinegar is a common method for the preparation of pickles, sauce and chutneys. Salt is mostly used as a preservative in pickles in combination with acid. Sodium chloride is used in brines and curing solutions or is applied directly to the food. The quantity of salt necessary to inhibit growth or harm the cells varies with the type of microorganisms. However, the minimum concentration of salt to act as a preservative is about 12%. Salt (sodium chloride) exerts its preservative action
by performing the following functions:
? Causing high osmotic pressure resulting in plasmolysis of the microbial cells.
? Dehydrating food by tying up the moisture thus making it unavailabl for the growth of microorganisms.
? Salt lowers the water activity and thus has adverse effects on microorganisms.
? Affecting the solubility of oxygen in the food and thus inhibiting the growth of aerobic microorganisms.
? Salt ionizes to yield chlorine ions, which is harmful to microorganisms.
? Chlorine in sodium chloride is a good oxidizing agent & is, therefore, toxic to microorganisms.
 

Black pepper (Piper nigrum L.), famous as “Black Gold” and also known the “King of Spices” is the most important agricultural commodities of commerce and trade in India. It is the most important, most popular and most widely used spice in the World. Of the total spices traded internationally, black pepper accounts for 34 per cent. South West India is the traditional home of this important spice, particularly the Malabar Coast. Black pepper is also grown in tropical zones such as the Asia Pacific Region, mainly India, Indonesia, Malaysia, Sri Lanka, Thailand, China, Vietnam and Cambodia. Outside the Asia Pacific region, the crop is distributed in Brazil, Mexico, Guatemala, etc., totaling about 26 countries. It is grown successfully between 20°N and 20°S latitude and from mean sea level to 1500 meters above sea level. World’s black pepper production varies in the range of 2.7 to 3.35 tonnes annually. The major production share is contributed by Vietnam with an annual production of 80,000 tonnes. About 85 per cent of the World trade of pepper is determined by the largest pepper producing countries in the International Pepper Community (IPC). World export fluctuates around 1.5–2.5 lakhs tonnes per annum. Global black pepper supply has shown a drastic increase over last ten years except in 2008–09. Vietnam’s sudden increase in production has resulted in the massive global out put of 3–3.5 lakhs metric tonnes from 1.9–2.0 lakhs metric tonnes in late nineties. 

Coffee is grown at higher elevation across the Western Ghats between 750 and 1200 m amsl. It requires a certain degree of shade for its better performance.  The annual rainfall over the coffee growing tracts varies between 1400 and 2600mm, having uni/bi-model rainfall with prolonged dryspell from November to May. It is more so over North of the Western Ghats. The mean annual maximum temperature varies between 24 and 300C while the minimum between 15 and 180C. The difference between maximum and minimum temperatures (temperature range) varies between 5 and 160C across the coffee tract. The ‘Monsooned Malabar Coffee’ is a specialty coffee produced from the erstwhile ‘Malabar Region’. It undergoes certain changes in physical and biochemical characters when the coffee beans are processed during the summer monsoon (June to September). It is processed at Mangalore, located in Coastal Karnataka. The processing location experiences heavy rainfall of more than 1000 mm in July, followed by 950 mm in June and 600 mm in August. Out of 3264 mm of annual rainfall, 2852 mm is received during the monsoon period. It accounts more than 80 per cent of annual rainfall. The maximum temperature during the coffee monsooning period varies between 28 and 30°C while night temperature revolves between 22 and 24°C. Being located in the tropics along the West Coast, the crop processing environment in terms of surface air temperature is relatively uniform and moderate with a characteristic feature of heavy clouds and continuous rainfall during the monsoon period. These monsoon features are more predominant from the middle of June to August during which the coffee beans are subjected to monsooning. The coffee beans
bulge in the process of monsooning and the volume increases significantly due to absorption of atmospheric moisture. It is directly related to the monsoonal wind during which coffee beans are processed. The bulging was less in all the samples processed during monsoon 2003, which varied from 2.1 to 2.7 ml/100 number, while it ranged between 2.7 and 5.8 ml/100 number in the samples processed during monsoon 2004.

A) Conventional breeding techniques
Conventional breeding techniques for spices involve various methods to improve traits such as yield, quality, disease resistance, and adaptability. Here’s an overview of conventional breeding techniques applied to specific spices:
1. Black pepper (Piper nigrum)
• Selection: Choose superior plants based on traits like yield, quality of peppercorns, and disease resistance.

• Mutation breeding: Induce mutations to develop new traits or enhance existing ones.
2. Small cardamom (Elettaria cardamomum)
• Selection: Select plants with high yield, better quality, and disease resistance.
• Hybridization: Cross different varieties to improve traits such as pod size and essential oil content.
• Seed production: Improve seed production and quality through selection.
3. Large cardamom (Amomum subulatum)
• Selection: Identify plants with higher yield and better resistance to pests and diseases.
• Hybridization: Develop hybrids to enhance flavour and size of the cardamom pods.

Abstract
Toxicants, whether naturally occurring or synthetic, present significant threats to aquatic ecosystems, leading to severe ecological damage and health hazards. These pollutants—such as pesticides, heavy metals, microplastics, and pharmaceuticals—contaminate water bodies through various routes, including industrial discharges, agricultural runoff, and insufficient wastewater treatment. They interfere with biological processes, causing problems like neurological damage, reproductive issues, and changes in water chemistry. Understanding the processes of bioaccumulation, biomagnification, bioconcentration, bioavailability and detoxification is essential for grasping how these contaminants impact aquatic organisms and human health. The rise of emerging pollutants, like microplastics and pharmaceuticals, adds further complexity, posing new challenges to ecosystem stability. Addressing these issues requires effective management and mitigation strategies, including reducing pollutant sources, improving waste treatment, and utilizing advanced detection techniques. Through research on these toxicants and their interactions, it is possible to better evaluate their effects, craft effective environmental policies, and implement measures to safeguard both aquatic ecosystems and public health.

Respiratory tract disorders in domestic animals
The respiratory system is vital for efficient oxygen exchange, metabolic function, and overall health. Respiratory tract disorders in livestock speciesare among the most significant health challenges, leading to  economic losses in terms of reduced productivity, treatment costs, and mortality. Thesedisorders can affect the upper respiratory tract (URT), lower respiratory tract  (LRT), or both. Overview of common respiratory diseases in livestock, their aetiology, clinical manifestations, pathophysiology, diagnostic approaches, and management strategies are summarized as follows: -
1. Bovine Respiratory Disease Complex (BRDC)
? Species affected: Cattle
? Etiology: Multifactorial; involves viruses (Bovine herpesvirus-1, Bovine respiratory syncytial virus, Parainfluenza-3, Bovine viral diarrhea virus), bacteria (Mannheimia haemolytica, Pasteurella multocida, Mycoplasma bovis), and environmental stressors

It is a systematic method to solving problems through an examination of policy approaches.
It involves evaluating public policies, including their development, implementation and impacts, to determine their effectiveness in achieving desired outcomes. The process includes identifying relevant issues, assessing potential solutions, weighing the costs and benefits and recommending the most appropriate course of action.
Use of Policy Analysis in Decision-Making
Policy analysis combines qualitative and quantitative methods to assess policies’ implications on economic, social and political factors. It often includes stakeholder analysis, forecasting future scenarios and evaluating policy impacts using tools like cost-benefit analysis, risk assessment and statistical modeling
