Root crops are cool season vegetables growing for its fleshy root developed from the tap root and hypocotyl region. They are grown during winter in tropical and subtropical condition, throughout the year in hills and spring-summer in high altitude hills. The major root crops growing in our country include carrot (Umbelliferae), radish (Brassicaceae), beet root (Chenopodiaceae) and turnip (Brassicaceae). Two distinct types viz., asiatic or tropical types and European types present in these root crops except beet root. In beet root, European or biennial types only exist. The tropical types are annuals that does not require chilling treatment for flowering. Therefore, seed production of these types is taken up in plains but European types are biennials and they require vernalization treatment after vegetative phase for flowering. Hence, the seed production of biennial types is possible in hills. The seed productions of Asiatic varieties of root crops are done in Punjab, Haryana, U.P. and parts of Rajasthan and Gujarat. Whereas, the seed production of temperate varieties is done in Saproon valley, Kullu valley, Kalpa valley of H.P., Kashmir valley of J&K and selected location of Northeast region specially Sikkim and Arunachal Pradesh. The seed production of beet root is being done in high altitude hills of J&K. All the crops belonging to this group are similar in the cultural practices though they come under different family. All root crops prefer well drained loose and friable soil. Ridge or bed planting is mainly following in all root crops. They are direct sown crops and does not respond to transplanting. They are highly cross pollinated.

The two methods of seed production following in root crops are seed-to-seed method and root-to-seed method. The first method is followed for the production of truthfully labelled seed or certified seed as the seed yield will be more, but quality remains inferior to the second method. The breeder seed as well as foundation seeds require utmost quality hence root-to-seed is preferred for its production. In this method, the matured roots are harvested and the roots are inspected for its trueness. Only true-to-type roots are selected for replanting in the field for seed production and undesirable ones are discarded. The selection and rouging in seed crop are done on the basis of foliage characters and external and internal root characters (colour, shape, size, flesh colour, core size, pungency, indistinct rings etc.). The roots after selection are prepared for replanting by cutting one-third top (shoot) portion and one-fourth to one-half root cut. the prepared stecklings are replanted to obtain good yield of quality seeds. In case of turnip and beet, after selection, the tap root and tops of the roots are trimmed without injuring the crown portion and is replanted.

Introduction

Fisheries and Aquaculture remains to be an important source of food, nutrition, income, and livelihood to millions of people. Fish is an affordable and good source of animal protein, a good option to reduce hunger and malnutrition in the country. India has bountiful resources comprising inland, brackish and marine water along with diverse fish and shellfish species. Indian Fisheries sector evolved gradually over the years and became an important socio economic attribute for the nation. India is the third-largest fish and aquaculture producing country and accounts for about 16% of total inland and 5% of total global marine fish production respectively. In 2021-22, India’s total marine and inland fish production stood at 16.24 million metric tonne (MMT), which includes 12.12 MMT and 4.13 MMT from inland and marine sectors, respectively. The annual growth rate in the marine sector was observed at around 18.7 %, whereas inland sector achieved more than 7.76 % during 2021 22 ( Table 17.1).The fishery potential of the country has been estimated to the tune of 22.31 MMT out of which Marine fisheries potential is 5.31 MMT and Inland fishery potential is 17 MMT. (Table 17.3).

Marine fisheries activities are spread along the country’s long coastline (8118 km) and in the vast Exclusive Economic Zone (EEZ 2.02 million km2). The inland resources are in the form of rivers and canals (0.19 million km), f loodplain lakes (1.0 million ha), ponds and tanks (2.43 million ha), reservoirs (3.15 million ha), brackish water (1.18 million ha), saline/alkaline affected areas (0.24 million ha), and such others etc., covering about 9 million ha, providing livelihood to 16 million (Table 17.2). In this direction sea cage culture may play an important role in rapid expansion of seafood production at global level. In present scenario, due to limited availability of fish fingerling we may not expand sea cage culture to the optimum level. Therefore, need of hour is to strengthen the available infrastructure and other needed backward and forward support system enhancing for fish seed production apart from developing market linkages with diversification of species.

Carbohydrates are the macronutrients consisting of carbon (C), hydrogen (H), and oxygen (O) atoms. In simpler terms, carbohydrates can be defined as polyhydroxy aldehydes or ketones or substances, which yield them on hydrolysis. The general formula of carbohydrates is Cn (H2 O)n , where n is the number of carbon atoms. In nature, carbohydrates are the most abundant biological molecules. In the human diet, carbohydrates are one of the main nutrients that provide energy to the body. The green plants, through the process of photosynthesis, synthesize the carbohydrates.

Classification of carbohydrates

Carbohydrates are also known as saccharides, originating from the Greek word sakcharon, which means sugar. However, not all saccharides have a sweet taste. Carbohydrates can be classified into three distinct groups: monosaccharides, oligosaccharides, and polysaccharides. The number of sugar units determines this classification.

Monosaccharides

Monosaccharides, or simple sugars, are the most basic carbohydrates. They are the monomers that serve as the building blocks for forming polymers or complex carbohydrates. Monosaccharides are the most simple carbohydrates possessing carbonyl groups, i.e., aldehyde (CHO) and ketone (C=O) groups with two or more hydroxyl (OH) groups. Monosaccharide has the generic formula Cn (H2 O)n, where n is the number of carbon atoms. Monosaccharides are sugars that cannot be hydrolyzed further to form simple carbohydrates. These crystalline solids without color dissolve in water but remain insoluble in non-polar solvents.

Abnormal milk: It is milk that is not smooth and homogenous but is flaky, ropy, stringy, slimy, watery, discoloured or bad flavoured (Plate 1 & 2).

Abrassive peeler: It is equipment comprising a rotating drum lined with carborandum (an abrasive material) in which certain vegetables like potato and ginger are tumbled and exposed to the abrasive action of the carborandum lining, thereby facilitating separation of peel from the vegetables (Plate 3).

Absinthe: It is green liqueur which is flavored with wormwood, anise, and other aromatic herbs (Plate 4). Its commercial production is banned in ma ny countries for health concerns.

Absolute alcohol: It is water free alcohol. It contains atleast 99 per cent pure alcohol by weight and obtained by digesting rectified spirit over quicklime and redistilling the same.

Absolute density: It is the ratio of weight of certain volume of a substance at 1oC to that of weight of same volume of water at 4oC.

Absolute humidity: Absolute humidity is defined as kg of water vapour per kg of dry air at a given temperature and pressure. Absolute humidity is the mass of water vapour divided by the mass of dry air in a certain volume of air at a specific temperature. The warmer air absorbs more water than cooler one. Absolute humidity is the measure of water vapour or moisture in the air, regardless of temperature.

Absolute pressure: It is equal to atmospheric pressure minus vacuum pressure (Plate 5).

Absolute zero: It is a theoretical temperature characterized by complete absence of heat and motion and equivalent to exactly -273.15°C or -459.67°F (Plate 6).

Introduction

The purpose of this e-book is to outline the main hazards in food production and processing that could influence the safety of foods and thus the health and wellbeing of consumers. The suggestive actions to restrain the formation of compounds or organisms that may threaten the safety of a food will be discussed along with the legal and regulatory framework.

“Safe Food Now for a Healthy Tomorrow”

Food is the third most basic human need, after air and water. Only when food is safe can it contribute to our food security and health. When food is not safe, people cannot thrive, hunger and poverty cannot be alleviated, and a healthy life is not possible. Food safety has a significant impact on human health, and food, which is essential for human survival, comes from plants and animals. Food safety is a core tenet of One Health.

This chapter gives an overview of the main hazards such as physical hazards, chemical hazards, biological hazards, and adulterants in different types of foods and how the hazards influence the safety of the food along with health and well-being of the consumers. The effective way of management of these hazards and different hazard limits set by the regulators such as FSSAI, USFDA, EU AND CODEX along with labelling requirements for the hazards has been discussed in this chapter.

5.1 Participatory Approaches to Watershed Management

Community Engagement Strategies: Exploring methods for involving local communities in decision-making processes, project planning, and implementation, including participatory rural appraisal (PRA), stakeholder consultations, and community meetings. Exploring methods for involving local communities in decision-making processes, project planning, and implementation is essential for promoting ownership, sustainability, and effectiveness of development initiatives within watershed areas. Here are key community engagement strategies:

a. Participatory Rural Appraisal (PRA): PRA is a participatory approach that involves community members in assessing their own needs, priorities, resources, and capacities. PRA techniques, such as transect walks, social mapping, seasonal calendars, and wealth ranking, enable communities to identify and analyze local issues, strengths, and opportunities. PRA fosters dialogue, builds trust, and empowers communities to take ownership of development processes.

b. Stakeholder Consultations: Conduct stakeholder consultations to engage a diverse range of actors, including community members, local leaders, government officials, civil society organizations, and other stakeholders. Consultations provide opportunities for stakeholders to share their perspectives, knowledge, and concerns, and contribute to decision-making and project design. Stakeholder consultations ensure inclusivity, transparency, and legitimacy in development processes.

c. Community Meetings: Organize community meetings, village assemblies, or public forums to facilitate dialogue, consensus-building, and decision-making among community members. Community meetings provide platforms for discussing development priorities, reviewing project progress, and resolving conflicts collaboratively. They foster social cohesion, collective action, and community mobilization around shared goals and aspirations.

A. Successful Biological Control Projects

Biological control, the use of natural enemies to manage pest populations, has seen numerous successful implementations globally for example:

1. Control of Cottony Cushion Scale (Icerya purchasi)

The case of the cottony cushion scale, Icerya purchasi, in California's citrus orchards serves as a seminal example of biological control's efficacy. Originating from Australia, this pest posed a severe threat to the burgeoning citrus industry in California in the late 19th century. The story of its control through the introduction of natural enemies is not only a landmark in biological control history but also a demonstration of ecological problem-solving.

Background and Impact

Icerya purchasi is a sap-sucking insect that infests a wide range of host plants but shows a particular fondness for citrus trees. The infestation is damaging as the scale excretes a sticky substance known as honeydew, which promotes the growth of sooty mold, impairing photosynthesis and weakening the plants. The severity of the infestation threatened the economic viability of the citrus industry in California during the 1880s.

3.1. Introduction

Various procedures performed on reptiles often necessitate chemical restraint or general anesthesia. Even routine tasks like physical examination and transportation can pose challenges, particularly with large or uncooperative reptilian patients. For safety reasons, venomous species are typically evaluated under chemical restraint. The respiratory anatomy and physiology of reptiles differ significantly from those of more familiar mammals, influencing their response to commonly used anesthetic agents. Historically, anesthetics recommended for reptiles had notable metabolic effects, but inhalant anesthesia has become more popular in recent times. Nonetheless, in species capable of anaerobic metabolism, induction with these agents may not be feasible (Girling 2013).

Trees have been used in cropping systems since the beginning of agriculture. Throughout the world, at one period or another in its history, it has been the practice to cultivate tree species and agricultural crops in intimate combination. In the tropics, human beings underwent a transition from hunting/gathering to the use of domesticated plants and livestock. As a part of the process, they cut down trees, cleared the debris by burning and sowed crops in the ash enriched soil. It was the ‘slash-and-burn’ agriculture, a primary forerunner of the present-day agroforestry and a practice that might have originated in the Neolithic period, around 7000 BC.

There are innumerable examples of traditional land-use practices involving combined production of trees and agricultural species on the same piece of land in many parts of the world. Trees were an integral part of these farming systems and they were deliberately retained on farmlands to support agriculture. These practices are now known as agroforestry. However, the ultimate objective of these practices was not tree production but food production.

Introduction

The cold chain is a meticulously managed series of actions using specialized equipment to ensure products remain within a specific low-temperature range from production to consumption (ASHRAE, 2024; IIR, 2024). This unbroken sequence encompasses refrigerated production, storage, and distribution activities, safeguarding the safety and quality of perishable and thermo-sensitive goods like agricultural commodities (such as fresh produce, meat, dairy, seafood, chemicals, pharmaceuticals, flowers, wine, etc.), processed foods and pharmaceuticals (Aung and Chang, 2014; Awan, 2023). For climacteric fruits like bananas, custard apples, apples, pears, tomatoes, mangoes, and avocados, cold storage facilitates controlled ripening, extending the time between harvest and consumption. Cold chain management, integral to the overall supply chain, requires expertise in maintaining temperature, air quality, and adherence to regulatory standards. Any disruption in this process can lead to product spoilage and financial implications (FAO, 2019). The management of the cold chain system is crucial for preserving the freshness, taste, and nutritional value of fruits from harvest to consumption (Kader, 2003).

The chapter focuses on presenting the outcomes and analysis of the research, aiming to offer ample information for reaching accurate conclusions. Within this chapter, tables and models are frequently employed to reinforce the textual content. The discussion section plays a crucial role in interpreting the research results appropriately and establishing connections with other pertinent studies.

The distribution characteristics of the variable Age (x1 ) reveals that the respondents’ ages range from a minimum of 27 to a maximum of 71. The average age is 48.675, suggesting that the majority of respondents fall into the middle-age category. The standard deviation is 11.574, indicating the degree of variability in the ages. Furthermore, the coefficient of variance (CV) is 23.779 percent, indicating a high level of consistency in the distribution pattern of the variable.

The distribution pattern of the variable Family size (x3 ) shows that the family size ranges from a minimum person of 3 to a maximum of 10 persons. The average family size is 10.125 persons. The standard deviation is 1.397. The coefficient of variance (CV) is 23.882 percent which indicates a high level of consistency in the distribution pattern of the variable.

Introduction

Micro, small, and medium enterprises (MSMEs) dominate the Indonesian economy. These enterprises account for around 99 percent of all businesses in Indonesia and employ more than 95 percent of the total workforce across the country. They should be the primary engines of economic growth, although they generate only approximately 56 percent of the overall gross domestic product (GDP) of Indonesia. Around 80 percent of MSMEs are in the trading sector involved in buying and selling existing products/services). Within the MSME group, micro and small enterprises (MSEs), including those in the manufacturing industry, called micro and small industries (MSIs), i.e. business units with up to a maximum of 500 million Indonesian rupiah (IDR), are the ones that receive the most attention from the Indonesian government because they account for almost 99 percent of total MSMEs. So, compared to medium and large industries (MLIs), MSIs are the largest job creators in the country. These enterprises also have high resilience in various previous crises, including the COVID-19 pandemic. Their high resilience has played a role as a cushion for the economy because of their ability to survive periods of pressure and grow back faster and higher after pressure.

A scientific experiment is a planned research to obtain new facts or to confirm or refute the results of previous experiments. Research is usually conducted in a controlled environment to study the effect of one or more variables on observations. The objective of research may be to answer a question, verify a hypothesis, or estimate the effect of an independent variable on a dependent variable. After stating the research problem, we need to outline the methodology (or materials and methods) of the research, which includes developing an experimental design.

Scientific experiments are conducted to study the causal relationships between independent variable(s) and dependent variable(s). The researcher manipulates one or more independent variables and measures their effect on one or more dependent variables. Designing an experiment is planning an experiment. It is a complete sequence of steps taken before experimenting to ensure that appropriate data are obtained to perform a data analysis to get valid inferences about the problem. It must be seen that the data collected are relevant to the problem investigated. E.g., studying the effect of breed, age, feed, etc. on milk output. Here, the objects like breed, age, feed, etc. are called treatments. That is, any specific experimental conditions (like the addition of feed additives, new feed formula, etc.) applied to the experimental units are called treatments. The basic objects on which the experiment is done are called experimental units (E.g., a bird, an insect, an animal). However, the responses in all the experimental units receiving the same treatments may not be similar, due to the inherent differences in the experimental units, called experimental error, caused by extraneous factors.

An animal disease is an economic process in the farming system, as it consumes a considerable amount of scarce economic resources that would have been otherwise productively utilized by the animals and results in negative benefits to society. Hence, while measuring the losses attributable to animal diseases, the manifestation of such losses and the factors influencing such losses may also be identified, which require modelling the ways by which the negative effects of the diseases are exhibited. A description of such models and their procedures is essential to understand the comprehensive effects of diseases. We will list and describe such models and tools in this chapter.

11.1 CORRELATION ANALYSIS

While simple descriptive statistical tools are adequate to estimate the economic effects of animal diseases, these tools cannot measure the nature and strength of the relationships between two or more variables. However, the statistical knowledge can effectively be used to understand Various statistical measures studied so far, like measures of central tendency and dispersion and skewness, relate to one variable only. However, there are many situations where there are several problems involving the use of two or more variables. Although correlation analysis is only a bivariate technique like t-test, ANOVA, and Chi square test, we will briefly see about correlation in this chapter, as it is also a part of multivariate analysis. The first step is to determine which bivariate analytical tool we need to adopt to test the study hypothesis.

Horticulture sector, comprising fruits, vegetables, floriculture, medicinal and aromatic crops, mushroom, spices and plantation crops, had witnessed phenomenal growth in production and productivity during the last two decades. Resultantly, horticulture in India is recognised as one of the fastest growing sectors in the world. The production has reached to 351.92 million tonnes in 2022-23 as compared to 231 million tonnnes in 2010. Progressive urbanization, increased spendable income and awareness for balanced and nutritious food have contributed towards increasing demand of horticulture produce. The increasing demand coupled with higher income returns per unit area has triggered this growth pattern, which has been largely possible due to policy environment to support horticulture both for research and development.

Coconut, arecanut and palmyrah, which hold significant cultural and historical importance in India, have been the primary focus of cultivation efforts. Cocoa, a relatively recent addition to India, serves as a companion crop to coconut and arecanut, contributing to the economic well-being of farmers nationwide. However, the current situation emphasizes the crucial role of value addition and product diversification in stabilizing prices. Despite the initial stages of value addition in India’s palm crops, recent innovations and established value chains have the potential to empower farmers as entrepreneurs, thereby augmenting their income. Moreover, the value-added products from these palms have enormous export potential. This chapter explores the advancements in value-added products and the diversification of coconut, arecanut, palmyrah, and cocoa, providing insights into opportunities for cottage or small-scale industries.

The term ‘mycorrhizae’ was coined more than a century ago (Frank 1885) describing that the roots of most plants are colonized by fungi and transformed into fungus roots organ. Mycorrhizae result from a mutualistic symbiosis between plant roots and certain fungi. Roots of most flowering plants live in mutual symbiosis with mycorrhizae which bio-tropically colonise the root cortex and extra-metricial mycelia help the plant to obtain plant nutrients from soil (Barea, 1991).

These fungi are ubiquitous in soil and are found in the roots of many Angiosperms, Gymnosperms, Pteridophytes and Thallophytes (Mosse et al., 1981). The mycorrhizal fungi perform the function of root hairs. The fungus takes carbohydrates from the plant and in turn supplies the plants with nutrients, hormones and protects it from root pathogens. The dependency of fungal species on host plant ranges from obligate to facultative (Brundrett, 2002; Read and Perez-Moreno, 2003). The mycorrhizal plants have greater tolerance to toxic heavy metal, nigh soil temperature, soil salinity, unfavourable soil pH and to transplantation shocks.

They play an important role in increasing plant growth and nutrients uptake (Bagyaraj, 1992, VasanthaKrishna and Bagyaraj 1993). These fungi can be used to promote biotechnologically developed plant in soil (Varma and Schuepp 1994).

Formulation is a word that can be used in a lot of different ways, but at its core, it means putting things together in the right way, usually by following a formula. Insecticides come in different forms, which are called formulations. A formulation is just the way a product is used. The chemical or biological makeup of a pesticide and its active ingredient (also called the active substance) determine how it works on living things. Most of the time, the active ingredient is mixed with other things, and the product as it is sold will need to be weakened even more before it can be used. Formulation makes a drug easier to handle, store, and use. It can also have a big effect on how well it works and how safe it is.

Insecticides come in many different forms because the active ingredients vary in how easily they dissolve, how well they kill pests, and how easy they are to handle and move. The pesticide is made up of both active and non-active (used to be called “inert”) chemicals. The manufacturer will need to know the identity of the pest, as well as details about its feeding behavior, reproduction, and life cycle, in order to create an effective formulation. Manufacturers also take into account factors including surface and equipment type, runoff and drift rates, pest habits, and safety when formulating insecticides. Inactive materials (adjuvants/ additives) are often added to insecticides to make them stick to the application surface or spread out over leaves. There are solvents (liquids) that dissolve the active ingredient, carriers (liquids or solids) that aid in the delivery of the active ingredient, etc.. Boosting the efficacy of active ingredients requires additives, such as spreaders, stickers, wetting agents, compatibility agents, foaming agents, etc.

The process of vaccine development involves numerous stages from research, discovery, innovation, formulation, testing, mass production, logistics, deployment and administering the vaccine to the target population. The COVID-19 pandemic expedited the endeavour to develop vaccine worldwide that is unparalleled in history. In addition to the steps that were similar during the usual vaccine development process, it called for stronger collaborative teamwork with stricter deadlines during the pandemic due to the emergency situation that built up everywhere (in its spread as well as severity). Research was expedited, potential candidate vaccines were discovered and the proofs of concept were designed that paved the way for pre-clinical efficacy testing. Multiple-step clinical trials to ascertain that the vaccines were effective and safe at least for ‘emergency use’ in human subjects were carried out swiftly. The emergency usage regulatory approval and recommending the usage pattern involved accelerated review procedures. It immediately followed rapid scaling-up for increased production in order to meet the need to save as many human lives as possible across the globe. The approved vaccines were simultaneously evaluated for safety through dedicated pharmacovigilance systems. The future of vaccine development shall also focus on improving the worldwide access to vaccines, managing the virus variants and streamlining mass vaccination campaigns. Comprehending the research, development and administration phases to create and implement life saving vaccinations within the regulatory framework amid international health emergencies as encountered during the COVID-19 pandemic and the enormous collective endeavours are highlighted in this chapter.

GREEN GRAM (Vigna radiata) & BLACK GRAM (Vigna mungo)
Fungal diseases

Cake mixes: Powdered formulations containing all the ingredients required to make cakes.
Cake mixtures: The five important cake mixtures are basic, Victoria sponge, Genoese, pound and fatless. The first two use a chemical raising agent; the last three rely on air beaten into the egg for raising.
Cake: Soft bakery products produced by baking a batter containing flour, sugar, baking powders and beaten eggs, with or without shortenings. It may also incorporate root vegetables, principally carrot. According to the final product, other ingredients are also included, such as flavourings, nuts, chocolate and dried fruits.

Fruits and vegetables are one of the most consumable commodities globally and also serves as an important ingredient in human dietaries. There are a lot of different varieties of fruit and vegetable and the prices keep fluctuating of the products. The production of fruit and vegetables needs to be handled, processed, or utilized properly. The costs involved in preventing the losses are always cheaper than the cost of production, therefore processing receives higher attention in recent years. The fruits and vegetables processing industry was earlier highly unorganized but due to the increasing demand for processed
food, the industry has started attracting investors. India facilitates the fruits and vegetables processing industry in obtaining its primary resources; India is the second-largest producer of fruits and vegetables. The global fruit and vegetable processing market includes the global fruit & vegetable processing equipment market and processed fruits & vegetables market. There are different methods included in fruits and vegetable processing that helps in increasing the life of seasonal fruits and vegetables are canning, dehydration, freezing, pickling, etc.
Crystallized Fruits
Candied fruit when covered or coated with crystals of sugar, either by rolling in finely powdered sugar or by allowing sugar crystals to deposit on them from dense syrup are called crystallized fruits.

Cauliflower
Cauliflower, Brassica oleracea L var. botrytis under the family Brassicaceae (Cruciferae) having chromosome No. 2n = 2x =18 is the most popular vegetable among the cole crops, particularly in Asia. It is grown in all continents of the world,= of which Asia is the leading one followed by Europe and covers small acerages in North America, South America, Africa, Australia and New Zealand. India and China together have about 60 % of total cauliflower area of the world. Cauliflower is used in different curry and fry preparations with potato, garden pea, sweet pepper and other vegetables. It contains high quality proteins and good in stability of vitamin C after
cooking. Frozen products are also prepared from cauliflower. It is rich in minerals such as potassium, sodium, iron, phosphorus, calcium, magnesium, etc.
Origin, domestication and adaptation in India
The cole crops have originated from the wild diploid species Brassica oleracea var. sylvestris mainly by mutation, human selection and adaptation. This wild species, a leafy kale-like plant which occurs in the northern shore of the Mediterranean Sea an along the lime cliffs in north-eastern England and North Sea is the progenitor of th cultivated kale and leafy non-heading cabbage. Probably kale was the first cole crop to have selected and adapted by man. From this leafy kale-like plant (Brassica oleracea var. sylvestris), other cole crops viz., kale, collard, broccoli, cauliflower and cabbage have been descended.

Introduction
The nervous system in animals is a complex group of highly specialized cells capable of collecting and transmitting information in response to external stimuli via receptors and highly specialized sensory organs. It aids in the regulation of muscle coordination, the release of hormones, neurotransmitters, and other chemical mediators, all of which facilitate numerous bodily activities.
The nervous system is divided into two systems: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system. Within these systems, there is another autonomic nervous system (ANS), which is distinguished by higher centers of the hypothalamus, midbrain, pons, and medulla, as well as tracts and nuclei in the spinal cord. The ANS is further divided into sympathetic and parasympathetic
systems, which help maintain homeostasis and activate emergency mechanisms in response to external stimuli. The brain is normally covered by three meninges: piameter, arachnoid, and durameter. These meninges create three spaces: the subarachnoid space (between pia mater and arachnoid), the subdural space (between arachnoid and dura mater), and the epidural space (between dura mater and the ligamentum flavum in the spinal canal). The subarachnoid space includes cerebrospinal fluid, which is isolated from cerebral blood by the morphological and enzymatic activity of cells with tight junctions that regulate intercellular diffusion and solute exchange inside the cells. These cells form a barrier known as the “blood-brain barrier”.
The blood-brain barrier works as a selective permeable membrane, allowing only certain chemicals and medications to pass through while excreting essential components from the central nervous system via energy-dependent efflux pumps like p-glycoprotein. These proteins are encoded by genes such as ABCB1, and mutations in them can result in severe effects such as Ivermectin poisoning in the Colie breed of dogs. Similarly, it aids in the relative isolation of the neurological system from the immune system by establishing an immune-suppressive parenchymal milieu. However, various infections, trauma, and developmental defects can result in underdevelopment or damage to different cerebellar structures. As a result, depending on the portion implicated, it might cause changed behavioral changes in animals such as muscle incoordination, depression, and paralysis. These clinical symptoms may be excitatory.

The global economy has adversely been affected to a considerable extent due to weather related disasters like droughts, floods, heat waves and cold waves which are not uncommon in the recent past due to global warming and climate change. For the first time, the year 1998 was declared as the weather related disastrous year globally. The year 2015 was the warmest year globally, again. Such weather phenomenon of warming more and more year after year was noticed in the current decade as well when we look at 2023 and 2024. The year 2010 was the warmest year ever recorded, followed by 2009 in India. The occurrence of floods and droughts, cold and heat waves adversely affected the Indian foodgrains production to a large extent across the Country in one or other region as seen in 2014, 2012, 2009, 2004, 2002 and 1987. The cold wave in winter 2003- 04 across the Northeast region of the Country and the heat wave in summer 2004 across the same region are still in memory to understand the ill effects in agriculture/horticulture/poultry/inland fisheries sectors. Model simulations
indicate that a marked increase in rainfall and temperature over India would be seen during the current century. The maximum expected increase in rainfall is likely to be 10–30% over the Central India. Temperatures are likely to increase between 2 and 30Cby the end of 2100 A.D. However, steps taken towards the green energy across the world may yield results not to allow atmospheric global temperature beyond 1.5 to 20C. Greater number of high surges and increased occurrence of cyclones in post monsoon period along with increased maximum wind speed are also expected along the East Coast of the Country. The summer droughts and heavy rains leading to waterlogging, floods and landslides during the monsoon period is a threat to plantation crops which are predominantly grown in the Humid Tropics like Kerala (8°15` N and 12°50`N latitudes and between 74°50`E and 77°30`E longitudes).

Seed production in spices varies depending on the specific crop and its biological haracteristics. Below is an overview of the seed production methods for each of the spices you’ve mentioned:
1. Ginger (Zingiber officinale)
• Propagation method: Ginger is propagated through rhizomes rather than true seeds. Selected healthy rhizomes are cut into pieces, each with at least one viable bud (eye).
• Planting: The rhizome pieces are planted in well-drained soil with high organic content.
• Maintenance: Regular watering and mulching are essential to maintain soil moisture. Weeding and pest management are also crucial.
• Harvesting: The rhizomes are harvested 8-10 months after planting. Some are reserved for the next planting season.
2. Turmeric (Curcuma longa)
• Propagation method: Similar to ginger, turmeric is propagated using rhizomes.
• Planting: Rhizomes are cut into pieces with at least one bud each and planted in a prepared field.
• Maintenance: Requires consistent soil moisture, so mulching and irrigation are essential. Regular weeding and protection against pests and diseases are necessary.
• Harvesting: Rhizomes are harvested 7-9 months after planting. Selected rhizomes are stored for the next planting season.

Livestock has been essential for Indian agriculture since prehistoric times. Livestock is crucial for tripling farmers’ revenue, for bovines—particularly cattle and buffaloes—play a crucial role in the economy. India has the
largest number of livestock owners, with a wide variety of livestock and poultry breeds that are essential to the socioeconomic advancement of rural communities. The production of consumables and maintaining the country’s food security are inextricably related to the livestock and agricultural sectors. Numerous illnesses have a detrimental effect on the health and productivity of livestock and are highly significant economically. Livestock illnesses have negative effects on producers, costing them money in upkeep, resources, and production.
Protozoal infections are a major contributor to the global burden of infectious diseases and have a profound effect on health, society, and the economy. Nearly one-sixth of the world’s population is at risk of dying from serious diseases like malaria (Plasmodium spp.), African sleeping sickness (Trypanosoma brucei), Chagas’ disease (Trypanosoma cruzi) and various forms of cutaneous and visceral leishmaniasis (Leishmania spp.). Although the burden of protozoal diseases primarily affects tropical and subtropical regions, environmental changes and ecological modifications brought about by both natural and manmade factors have had and are likely to continue to have a significant impact on the emergence and spread of these infections in high-income nations.

Introduction
Similar to the procurement of raw materials in a factory, milk collection is one of the initial and essential steps for a milk processing or marketing company. A successful milk collection system combines efficient route planning, quality control, and effective farmer engagement. By prioritizing technology integration, cold chain management, and regulatory compliance, dairy companies can establish a reliable and sustainable milk procurement system that meets both operational and quality standards.
India dairy sector depends on smallholder individual milk producers, each contributing between one to a few litres of milk per day. Typically, milk production takes place in rural areas, while the demand is concentrated in urban centres. However, rural producers often face significant marketing challenges due to the dispersed nature of milk production, scattered settlements, and inadequate supply infrastructure. Therefore, milk needs to be collected, transported, and marketed from villages to cities to ensure profitable returns for producers. Milk is usually collected from producers at designated collection points in rural areas, which serve a large number of small suppliers. This approach minimizes the need for individual chilling and storage facilities. Collection points should follow the same hygiene standards as dairy processing facilities. Milk should arrive at a chilling station within four hours of milking, especially in warmer climates. There, it must be quickly cooled to below 4°C to preserve its quality. Bulk milk coolers of required capacity are installed for the chilling and storage of milk at low temperature till it is transported to the processing plant.

12.1 Introduction
Having explored the dynamic realm of Numerical Weather Prediction, which focuses on forecasting the atmosphere’s state over days to weeks, we now shift our focus to a broader, longer-term perspective: Climate Data and Analysis. While weather describes the atmospheric conditions at a specific place and time, climate refers to the long-term average pattern of weather in a region, typically spanning decades or longer. Understanding and analyzing climate data is paramount for comprehending our planet’s past climate, identifying ongoing changes, and projecting future scenarios in a warming world. The study of climate is fundamentally data-driven. Unlike the instantaneous snapshots used in weather forecasting, climate analysis requires vast historical records, often extending back centuries or even millennia, to discern natural variability from human-induced changes. This data comes from a diverse array of sources, including instrumental records (thermometers, rain gauges, barometers), satellite observations, and proxy records (tree rings, ice cores, sediment layers) that provide indirect evidence of past climate conditions. The sheer volume and heterogeneous nature of this data present unique challenges and opportunities for analysis.
This chapter will delve into the essential aspects of climate data and the methodologies used to analyze it. We will begin by exploring the various types of climate data available, understanding their strengths, limitations, and how they are collected and curated. Crucially, we will examine how this data is used to characterize climate variability – the natural fluctuations within the climate system – and to detect climate trends, particularly those associated with global warming. We will introduce key climate indices that summarize large-scale atmospheric and oceanic patterns, providing simplified metrics for
understanding complex interactions.

An agricultural weeder is a tool designed to remove weeds from fields or gardens. It can be used manually or attached to machinery like tillers and power weeders. Weeding is necessary to eliminate unwanted plants that compete with crops, ensuring better growth and profitability. Effective weed management is crucial in crop production, as weeds can reduce yields by stealing nutrients and attracting harmful pests. In recent years, research has focused on non-chemical methods and environmentally friendly alternatives to herbicides for weed control. Mechanical weeding is often the most cost-effective solution. Tools like rotary weeders, mechanical hand weeders, and wetland weeders are generally effective, with wetland versions gaining popularity due to their ability to function in shallow water. These tools uproot weeds and bury them in the mud through their pull-and-push action, making them both safe and eco-friendly. Weeding should be done at least three times during a growing season, with early weeding being the most effective for completely eliminating young weeds.
FUNCTIONS OF WEEDING EQUIPMENT
Secondary tillage equipment is often used for weed management. Weeders help control weeds between planted crops or before sowing. Some weeding machines use mechanical methods to remove unwanted plants without the need for chemicals.
Usage Instructions
• Early weeding is essential: Perform the weeding within 20 days after sowing.
• Delayed weeding can lead to competition between paddy and weeds, harming the crop.
• Move the weeding machine back and forth between rows.
• Conduct a second round of weeding after 15 days, and if possible, a third.

Introduction 
India’s digital transformation over the past decade has emerged as a defining feature of its governance and developmental strategy, propelled by the ambitious Digital India initiative launched in 2015 by the Ministry of Electronics and Information Technology (MeitY). With a vision to transform India into a digitally empowered society and knowledge economy, the initiative seeks to harness the power of information and communication technologies (ICT) to make governance inclusive, efficient, transparent, and responsive. Digital India marks a paradigm shift in how public administration operates, embedding technology at the core of policy delivery, citizen engagement, and institutional coordination across sectors and tiers of government. Creating a robust and scalable digital infrastructure is at the heart of this transformation. Major projects like BharatNet aim to connect 2.5 lakh Gram Panchayats via high-speed optical fiber, of which over 1.5 lakh were connected by 2020. Simultaneously, establishing more than 3.7 lakh Common Service Centres (CSCs) has extended digital service delivery to rural and remote areas. These CSCs function as inclusive access points, offering health, education, agriculture, banking, and public utilities services in a culturally and linguistically localized format, catalyzing rural digital entrepreneurship and last-mile inclusion. India’s approach to digital governance extends beyond infrastructure to encompass citizen-centric digital services and platform-based public service delivery models. Platforms such as UMANG, eHospital, BHIMUPI, DigiLocker, eCourts, Tele-Law, and eWay Bills have simplified citizen interaction with the state, enhancing the ease of living and improving administrative efficiency. The Government eMarketplace (GeM) has transformed public procurement by making it more transparent, efficient, and accessible for small businesses and start-ups. The Jan Dhan–Aadhaar–Mobile (JAM) trinity has revolutionized welfare delivery by facilitating Direct Benefit Transfers (DBT) into verified bank accounts, eliminating intermediaries, and saving over ?1.7 lakh crore by 2020.

Surface: border strip, furrow, basin and check basin
Sub-surface
Micro-irrigation: drip, sprinkler; Pichter and bottle
Definition of Irrigation Method
Application of irrigation water to cropped field by different types of layouts is called as irrigation methods. The methods of irrigation initially might have been started to check the over flow of water from one field to another. But today, it has become necessary to save the water by proper methods to arrest run-off loss, percolation loss, evaporation loss etc., and to optimize the crop water need. Hence, irrigation method can be defined as the way in which the water is applied to the cropped field without much application and other losses, with an objective of applying water effectively to facilitate better environment for crop growth.
Factors Influencing Irrigation Methods
Soil type: The soil physical properties such as texture, structure, porosity, infiltration rate, etc. influence the selection of irrigation methods. Heavy texture soil restricts water movement than light texture soil wherein water move freely to deeper sections due to high porosity. Single grain structure soil allows water freely to move downward compared to other structures
Soil depth: If soil is shallow which holds less water, leveling and forming bunds etc. to hold? Maximum water is to increase the irrigation interval. Similarly if the soil is deep, it holds more water and needs longer irrigation interval. Accordingly, the irrigation methods can be selected.
Topography of land: In undulating topography, it is very difficult to adopt normal methods of irrigation. The slope of the land also decides the methods to be adopted. If the land is more sloppy, basin method cannot be used. In this condition strip method can be used. For undulating topography instead of strip or basin method, sprinkler or drip methods can be used.

5.1 Introduction
Since the early days of human interaction with the environment, particularly in industrial settings, humans have continually been “shaped” to meet the demands of their surroundings. Historically, people have often endured significant discomfort and limitations without much complaint. In metaphorical terms, individuals have adapted by extending their reach to operate controls that were difficult to access, pushing their perceptual abilities to detect faint sounds or invisible signals, and compressing their bodies to fit into cramped workspaces. Cognitive abilities have also been stretched to accommodate monotonous or tedious tasks. However, as both work environments and machines have grown more complex, these challenges have become increasingly significant. A poor “fit” between the human operator and their environment has led to countless accidents, decreased productivity, and errors in many industries. The primary goal of ergonomics is to assess human capabilities and design the environment to align with these capabilities. Instead of attempting to adapt humans to jobs, ergonomics strives to “fit the job to the person.” This approach aims to optimize safety, efficiency, and comfort by aligning machine requirements with the operator’s abilities. By establishing a connection between humans and machines, ergonomics ensures that machines communicate information to the operator through their sensory systems, prompting a response that may alter the machine’s state. Key environmental factors such as temperature, humidity, lighting, sound, and visual conditions have a direct impact on both human well-being and the quality of production. The design of both the human workspace and the equipment used can be highly effective if the environment is conducive to the operator’s needs. Therefore, it is essential to study each environmental factor from an ergonomic perspective to ensure a comfortable and productive environment for workers. This includes designing jobs, equipment, and considering human anthropometric measurements in the design process.
5.2 Heat
Heat stress occurs as a result of the combined effects of environmental conditions, physical exertion, and clothing. The key environmental factors influencing heat stress include air temperature, humidity, radiant heat, and air movement, all of which can significantly affect work performance. Heat strain refers to the

Drought, a recurring and often devastating feature of climate variability, presents a unique challenge due to its slow onset, complex nature, and farreaching consequences. Unlike hazards with clear event boundaries, drought manifests across diverse spatial and temporal scales and impacts nearly every facet of the environment and human activity. Effectively understanding and managing this phenomenon necessitates an equally comprehensive approach: drought monitoring. This chapter introduces the essential concepts and methodologies underpinning this critical field, highlighting the remarkable breadth required to capture the full picture of drought conditions. • The scope of drought monitoring is inherently vast. Geographically, it spans from tracking localized water stress affecting a single farm or watershed to assessing conditions across entire regions, nations, and continents. Temporally, monitoring efforts must consider short-term deficits unfolding over weeks or months (critical for agriculture) as well as long-term hydrological imbalances developing over seasons, years, or even decades (impacting reservoirs and groundwater). Understanding current conditions crucially relies on comparing them against a deep historical context, requiring decades of baseline data

Group dynamics and formation represent fundamental processes in community mobilization that determine how individuals come together to form collective entities capable of achieving shared goals while building social capital and institutional capacity that can sustain long-term community development efforts. Understanding these processes provides essential insights into how communities can organize themselves effectively while creating groups that can navigate complex challenges and maintain cohesion through the inevitable difficulties and conflicts that arise during collective action initiatives. The science of group dynamics encompasses the complex social, psychological, and organizational factors that influence how groups form, develop, function, and achieve their objectives while building understanding of the internal processes that enable or constrain group effectiveness and sustainability. This knowledge has evolved through decades of research in social psychology, organizational behavior, and community

Nanotechnology has emerged as a transformative interdisciplinary field, enabling the design and manipulation of materials at the nanoscale with exceptional physical, chemical, and biological properties. Nanoparticles (NPs), the most fundamental components of nanotechnology, exhibit unique size-dependent characteristics such as high surface area-to-volume ratio, enhanced reactivity, and tunable functionalities that make them valuable in diverse applications including agriculture, medicine, and environmental management. This chapter provides a comprehensive overview of the classification, synthesis, and characterization of NPs. NPs are categorized based on origin, composition, dimensionality, and morphology, encompassing organic, inorganic, and composite forms. The synthesis of NPs follows two major approaches—top-down and bottom-up—employing physical, chemical, and biological methods. Conventional techniques such as ball milling, laser ablation, and chemical reduction are discussed alongside emerging green synthesis strategies that emphasize sustainability and biocompatibility. Characterization techniques including UV–Visible spectroscopy, DLS, SEM, TEM, FTIR, XRD, and AFM are highlighted for determining nanoparticle

Introduction Biochemical techniques are a set of methods/tools used to analyze and study biomolecules, cellular processes of body and disease diagnosis. The techniques form the cornerstone of modern research and are applied in various fields such as medical science, forensic science, drug discovery as well as environmental studies. Briefly, such techniques are used to isolate, analyze, and manipulate biomolecules such as proteins, nucleic acids, lipids, and carbohydrates. It is therefore imperative to understand the principle of biochemical techniques for pursuing a career in biological science such as Biochemistry, molecular biology or Biochemistry. Biochemical techniques offer several uses across multiple scientific areas such as: • Medical Research: In the identification of biomarkers, diagnosis of disease conditions such as diabetes and cancer and development of therapeutic interventions. • Pharmaceutical Industry: In this biochemical

MANIFESTATIONS OF URINARY SYSTEM DISEASES Urinary tract diseases in farm animals  are generally clinically characterized by        pain    and        difficult    urination    (dysuria);    alterations    in    urine    volume    and    its composition; rupture of the renal pelvis, bladder and urethra; and inadequacy of nervous control of urination. Clinical Signs • Dysuria and abdominal pain are common expression of discomfort owing to urinary tract diseases. Acute abdominal pain is rarely seen in cattle due to sudden distension of renal pelvis (pyelonephritis), ureter or renal infarction. Abdominal pain from urethral obstruction leading to distension of urinary bladder is clinically manifested by tail switching, kicking at belly, straining at urination and grunting. Horses with acute tubular nephrosis may show signs of renal colic (arching back, rubbing perineum and tail head). Dysuria (frequent passage of small amounts of urine with pain) is associated with cystitis, vesicle calculus and urethritis • Uremia is commonly seen in cases of acute renal failure and is manifested

5.1 Afghanistan Overview of the Agri-Food Economy Agriculture is a vital sector in Afghanistan, contributing around 25% to national GDP and employing nearly 60% of the workforce (World Bank, 2023). The country’s agro-climatic diversity enables the cultivation of staple crops such as wheat, along with high-value horticultural products like pomegranates, grapes, almonds, and apricots (FAO Afghanistan, 2022). Despite this potential, the sector is highly vulnerable due to climatic extremes, institutional fragility, and limited infrastructure. Key Challenges • Conflict-related Disruptions: Persistent conflict and political instability have disrupted agricultural activities and supply chain networks, undermining both domestic

Modern farm planning involves nonlinear, discontinuous and multi-objective problems that conventional optimization methods may not solve effectively. This chapter examines Genetic Algorithms, Particle Swarm Optimization and Differential Evolution for improving agricultural resource allocation. These nature-inspired techniques can simultaneously address crop yield, water use, fertilizer application, environmental effects and financial viability. Their integration with deep-learning forecasts and crop-simulation systems enables more realistic optimization. Multi-objective evolutionary algorithms identify Pareto-optimal alternatives, allowing decision-makers to balance productivity and ecological sustainability. The chapter also emphasizes explainable artificial intelligence, economical implementation and farmer usability as necessary conditions for transferring evolutionary optimization methods from experimental research to practical farm management.

Quality has emerged as a decisive source of competitive advantage in the global apparel industry. Liberalization and increasing international competition have encouraged apparel manufacturers to adopt quality-management practices throughout their operations. Sustained quality must be maintained from the procurement of fabrics and other raw materials through manufacturing, finishing and delivery. Although finance, labour and resources are important, they cannot ensure long-term growth when customers are dissatisfied. Modern consumers have numerous choices and expect dependable products at reasonable prices. Consequently, manufacturers must provide consistent quality, value for money and customer satisfaction to build product confidence, brand loyalty and sustainable business growth.

Artificial intelligence is becoming an important technology for transforming agricultural decision-making and farm management. This chapter introduces the fundamental concepts, tools, and applications of AI in agriculture. It explains how machine learning, deep learning, computer vision, predictive analytics, and intelligent systems can process large volumes of agricultural data. AI applications include crop monitoring, disease detection, yield prediction, precision input management, and automated decision-making. The chapter also discusses the major drivers of AI adoption, including increasing food demand, resource constraints, climate change, and labour shortages. Examples of AI-based agricultural applications demonstrate its potential to improve productivity, sustainability, resource efficiency, and resilience.

Definition and Significance

Garden Components are the garden features that form the expressions of garden, adding charm to the basic garden landscape and constitute its style, contributing strongly to its texture and structure. Thus, garden features are important as they provide face lift to the garden skeleton, giving it a filling effect with charismatic appeal. Garden features include garden wall, fencing, arches, pergolas, hedge-edge, topiary, etc. Creating sudden and unexpected change of scenery sometimes reveal good contrasts. Thoughtful planning of garden features make an invaluable contribution to garden design. It is possible to design a garden with a large number of man-made artistic items. However, indiscriminate and haphazard use of these items results in clutter. Further, new and strange features in the garden always attract visitors and give unbounded pleasure. During ancient time, because of the traditional style of architecture and high craftsmanship, garden features and adornments have played a big role in many famous gardens of the world. Selection of features and positioning of ornaments in a garden are the visible evidence of the owner’s taste of nature and aesthetic sense. Whatever features are chosen, they must add charm, create an atmosphere of naturalistic design and improve the quality of landscape design. Garden features and ornaments are many, but they must be utilized in the design with restraints. Some important garden features are described below.

1. INTRODUCTION

The past hundred and fifty years of this millennium have witnessed an unbelievable pace of scientific and technological development. Modern science has attempted to a great extent and succeeded in realizing the dreams and fantasies of philosophers and scientists of the previous centuries. Plant genetic engineering via., nucleus is a mature technology that has been used productively for research and commercial applications. However, plants have an unassuming second genome inside the tiny organelles called as plastids. Although this small circular DNA carries a fewer genes than its nuclear counterpart, researchers say its potential for genetic engineering far outstrips its size. The ability to introduce foreign genes at specific locations on a chloroplast has been acquired very recently. It is expected that certain limitations of nuclear genome transformation methods in terms of protein expression and environmental safety can be overcome by site-specific introduction of genes into plastids. Thus the plastid engineering forms a viable alternative serving as another milestone in the field of plant biotechnology.
