The movement of water from soil to the crop canopy and leaves to provide water for transpiration and the effect of weather factors on transpiration is most important area of study. When the crop is just sown, there will be an only evaporation of water from the soil. After germination of seeds there will be emergence of seedlings. After the emergence of seedlings there will be formation of leaves. The small leaves start intercepting the incoming solar radiation and absorb some portion of solar energy, get heated and there will be evaporation turn off water from the stomata of the leaf. When water vapour escapes into the atmosphere through the stomata of leaf, the plant absorbs carbon dioxide which results in photosynthetic activity. During night time, there will not be any photosynthesis due to absence of sunlight. The plants use parts of the photosynthetic accumulate for its metabolic activity and the process is called maintenance respiration. The balance of the photosynthetic accumulate contributes to the expansion of leaves and increased dry matter accumulation in crop plans. The process of dry matter accumulation in plants is called crop growth. When the seedlings start growing, there will be formation of tillers or branches. When the leaves grow it reaches a stage when the crop will be completely shading the ground and the soil evaporation will be minimum and maximum amount of water is lost only through evapotranspiration (Fig.6.1).

Introduction
The emergence and spread of antimicrobial resistance has changed the landscape of infectious disease treatment, creating an urgent need for new diagnostic and therapeutic approaches4’7. Traditional phenotypic antimicrobial susceptibility testing, while remaining the gold standard, requires 24-72 hours for results and provides limited insights into resistance mechanisms. Limited turnaround time is often a constraint that requires empirical use of antibiotics, potentially driving the propagation of other resistance emergence as well as suboptimal patient outcomes. Thanks to mass spectrometry, clinical microbiology has greatly benefitted through the rapid detection of pathogens. However, the application is far broader than species identification. The integration of multiple omics fields like proteomics, metabolomics, genomics, and transcriptomics through mass spectrometry provides unprecedented means to unravel, predict, and combat antimicrobial resistance (AMR) on a molecular level. The use of a multiomics approach is demonstrated to show that AMR is a complex phenotype that arises from the intersection between genetic mutations, variations in gene expression, metabolic differences, and changes in protein structures that all act in unison to affect bacterial survival in the presence of antibiotics. The conversion of raw mass spectrometry outputs into clinical insights amenable to decision-making is dependent upon bioinformatics. Through the use of sophisticated computational methodologies, such as machine learning and network analysis, bioinformatics provides the means to incorporate heterogeneous omics datasets. Through this approach, resistance-related biomarkers can be identified, predictions for therapeutic efficacy can be made, and new targets for intervention can be identified. The intersection between high-resolution mass spectrometry, broad-based omic profiling, and strictbioinformatics provides a powerful platform for addressing the intractable challenge of antimicrobial resistance.

Introduction
The endocrine system consists of glands and cells that secrete hormones directly into surrounding tissues or into the bloodstream to regulate various physiological processes. These hormones help maintain homeostasis, working closely with the nervous system, especially through the hypothalamo-hypophyseal connection, where the endocrine and nervous systems integrate their functions.
Pituitary Gland (Hypophysis)
The pituitary gland, often considered the “master gland,” is formed from oral and neural ectoderm. It is divided into two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). Adenohypophysis: This portion develops from the roof of the stomodeum (primitive mouth) and consists of three parts: the pars distalis, pars intermedia, and pars tuberalis. It contains several cell types, including acidophils, basophils, and chromophobes, which secrete various hormones. For instance, acidophils release growth hormone (GH) and prolactin, while basophils produce hormones like adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), and gonadotropins (LH and FSH). The secretion of these hormones is regulated by the hypothalamus through releasing and inhibitory factors delivered via the hypophyseal portal system. Neurohypophysis: Originating from the floor of the diencephalon, the neurohypophysis consists of the median eminence, infundibular stalk, and neural lobe. It stores and releases antidiuretic hormone (ADH) and oxytocin, both synthesized in the hypothalamus and transported to the posterior pituitary. ADH regulates water balance, while oxytocin controls uterine contractions and milk ejection during lactation.
Hypothalamo-Hypophyseal System
The hypothalamus and pituitary gland form a unified control system. The hypothalamoadenohypophyseal system is responsible for regulating the anterior pituitary’s hormonal

4.0. Introduction

Quality is a measure of the degree of excellence or degree of acceptability by the consumer. By quality, one can differentiate the individual unit of a product from the other units and can determined the degree of acceptability of the individual unit by the consumer. The quality may also be defined in term of end use and may vary depending upon consumer’s perception and need. According to USDA Marketing Workshop Report (1951) “quality is the combination of attributes or characteristics of a product that have significance in determining the degree of acceptability of the product to the user”. For industry, quality is a measure of purity, strength, flavour, colour, size, maturity, workmanship and conditions or any other distinctive attributes of the product.

According to Code of Federal Regulations “Quality is the inherent properties of any processed product which determine the relative degree of excellence of such product and includes the effect of preparation and processing and may or may not include the effects of packaging or added ingredients/ additives”.

In the Radiochemical Laboratory

The following are some illustrative recommendation which may be used selected as a guide for setting up working rules :

General

No unnecessary materials should be brought into the laboratory. No unnecessary work should be done there.

Eating, drinking, and the use of cosmetics in the laboratory should be forbidden. Radioactive materials should not be place in milk bottles, soft drink bottles, or other vessels that might be inadvertently used for food purposes.

Record should be kept of radioactivity brought into the building and of its disposition.

Disease appears later part of the crop season mostly during blossoming period. The first sign of the disease is the appearance of small brown patches on the leaves mostly on basal leaves which starts from tip or margin of leaves and spread downwards or inward directions.

Agriculture faces increasing pressure from population growth, climate change, resource scarcity, land degradation, water shortages, and growing food demand. This chapter examines the major global challenges affecting agricultural productivity and food security. Climate variability, extreme weather events, declining natural resources, and changing pest and disease patterns create substantial risks for farming systems. The chapter discusses sustainable and climate-smart agricultural approaches for improving resilience and resource-use efficiency. It also highlights the contribution of artificial intelligence, precision agriculture, biotechnology, remote sensing, and digital technologies in addressing these challenges. Policy support, research investment, institutional cooperation, and equitable access to technology are emphasized for sustainable agricultural development

INTRODUCTION

Plants are susceptible to different types of pathogens, which are responsible for production of varied symptoms and causing losses. In the absence of the crops pathogens perpetuates in different manners and survival in the soil is one of the most important amongst these. Because of the constant presence of the pathogen in the soil, these become more destructive. These may reduce the plant growth, results in rotting of different plant parts, reduce yield or may cause the death of the plant. The destructiveness of soil borne pathogen increases because of the ability to survive in the soil as dormant structures for several years. Efficient control of soil borne diseases is thus difficult but can be achieved by employing various disease management practices in an integrated manner (Verma and Varma, 1992; Gupta, 1996, Gupta and Sharma, 1999).

Tending is the term applied to pre-harvest silvicultural treatment of forest tree crops at any stage after initial planting or seeding. In other words, tending is the intermediate treatments that forest vegetation receives after establishment of regeneration and prior to final harvest of the stand. These tending operations can occur throughout the life of the forest stand, but do not include efforts directed at establishing regeneration. Tending operations play a fundamental role in the improvement of quality and stability of forest stands. Tending the trees after planting creates favourable conditions for both the plants’ survival and to stimulate a healthy, vigorous growth. Tending operations keep the plants from being suppressed by natural vegetation. It essentially covers operation on the crop itself and competing vegetation. Weeding, cleaning and thinning are important tending operations. Even improvement felling comes under tending operations but regeneration felling is not a tending operation. The major objectives of tending are to maintain sanitation, provide sufficient growing space, and more light, water, nutrients, etc. to the tree crops.

In India, people are mostly vegetarian, depending largely on cereals and pulses, as their staple foods, which provide the main source of dietary proteins and calories. The proteins from pulses are known to be inferior quality, due to the deficiency of sulphur containing amino acids as well as due to other factors like digestibility, availability of amino acids, anti-nutritional factors, etc. The anti-nutritional factors present in this type of food, including their contents of enzyme inhibitors, lectins, flatulence factors, tannins, phytic acid and saponins. Anti-nutritional factors can cause detrimental effects to humans and animal growth and performance by impairing intake, uptake, or utilization of other food and feed components, or by causing discomfort and stress to humans and animals. The anti-nutritional factors mainly occur in pulses and grain legumes and foods and feed material prepared from grain legumes and pulses.

Substance which, from nutritional point of view, interferes with normal growth, reproduction or health when consumed regularly in amount existing in a normal component of diet should be considered as harmful and toxic. A significant part of human population relies on legumes as staple food for subsistence, particularly in combination with cereals. They are unique foods because their rich nutrient content including starch, protein, dietary fibre, oligosaccharides, phytochemicals (especially the isoflavones in soybean) and minerals. Their nutritional contents contribute to many health benefits to human.

Sending a message from one place to another place, which are physically separated from each other, is called Communication. The Communication Engineering or Communication Technology deals with the design and development of engineering systems to transmit information from its source, and at the same time, to receive the same information at a remote destination with reliability, accuracy and quality.

The term DNA sequencing refers to methods for determining the order of the nucleotide bases, adenine, guanine, thymine and cytosine, in a molecule of DNA. In molecular terms ,the definitive understanding of a DNA molecule comes from determining its nucleotide sequence.The function of a gene can be deduced from its nucleotide sequence,for example by comparing the sequences of genes with known functions.

The first DNA sequences were obtained by academic researchers, using laborious methods based on 2 – dimensional chromatography in the early 1970s.  Following the development of dye-based sequencing methods with automated analysis, DNA sequencing has become easier and orders of magnitude faster.  Knowledge of DNA sequences of genes and other parts of the genome of organisms have become indispensable for basic research studying biological processes, as well as in applied field like diagnostic or forensic research.  The advent of DNA sequencing has significantly accelerated biological research and discovery.

9.1. ITKS for Seed Treatment and Sowing

• Yield of almost all the crops depends on seed quality.
• Even if it is a quality seed, it should be a dried one because well dried seeds will have higher longevity and keeping quality.
• It better to change the seeds at least once in two years.
• To maintain the seed viability and prevent it from outside damage, the outer shell is not separated.
• The seeds are generally stored along with the leaves of neem (Azadirachta indica), pungam (Pongamia pinnata), notchi (Vitex negundo) and thumbai (Leucas aspera).
• Six weeks nursery period is enough for six months duration of the crop.
• Shallow sowing is followed in dry lands.
• Severing the broadcasted seeds in dry lands with soil.
• Dragging, over the fields, the thorny branches with weight over them for covering seeds the sown on dry lands.
• It is better to start planting from ‘Sani moolai’ (north east) of the field to get higher yields.
• It is better to perform sowing and planting operations during evening hours.

It also discusses the environmental impact, economic considerations, and emerging trends in baling methods. Through in-depth analysis and practical insights, this chapter offers a comprehensive understanding of how baling contributes to sustainable biomass management and resource optimization.

INTRODUCTION

Heterotrophic organisms, such as zooplankton, use phytoplankton as food, regenerating nutrients through metabolic processes and transferring energy to higher trophic levels. Zooplankton are involved in the conversion of waste matter into animal food that may be consumed, in addition to helping to shift food from the primary to the secondary level. These species act as a bridge in the food chain, carrying energy from the primary producers, planktonic algae, to the larger predatory invertebrates and fish that eat them (Kumari et al., 2008). Macróplankton (200–2000 μm), microplankton (20–200 μm), nanoplankton (2–20 μm), picoplankton (0.2-2 μm), and femtoplankton (0.02 0.2 μm) are the different sizes of plankton (Kumar et al., 2023).

The sensitivity of zooplankton to alterations in aquatic environments is significant. Differences in species composition, abundance, and distribution of body size can be used to identify the consequences of environmental disturbances(Joshi & Joshi, 2011). A number of variables, including temperature, sunlight, ocean currents, and nutrition availability, affect plankton populations. They are vital to ecosystems because they support carbon cycling, global biodiversity, and the general health of the oceans (Cottenie et al., 2001). An evaluation of the pollution state heavily depends on the interaction between phytoplankton diversity and environmental conditions. The diversity of algae found in the Chlorophyceae family is a key sign of the quality of the water. The differences in water quality can be attributed to a combination of natural and human-caused factors. Owing to extensive human activity, anthropogenic inputs from various sources are typically the main variables influencing the water quality of the majority of rivers, lakes, estuaries, and seas, particularly those that are next to densely populated areas(Jeyaraj et al., 2016). Living things, including plants, plankton, animals, and bacteria, are known as bioindicators, and they are used to monitor the state of the environment's natural ecosystem. They are known across the world as aquatic pollution indicator species. Every organic entity in a biological system gives information about the state of its surroundings. For example, plankton responds quickly to changes in the environment and is a valuable biomarker for determining the quality of water as well as a sign of pollution. Plankton is the best indicator of the health of aquatic flora and serves as an early warning system(Wadjikar et al., 2017). An ecosystem that is in balance is one in which beneficial interactions occur between the environment and living organisms. Since water quality is essential to maintaining an environment in balance, it is evident that it plays a crucial role in this relationship(Jeyaraj et al., 2016).

Rendering is the process of transforming deceased animals or condemned meat into valuable products, such as carcass meal. Traditionally, rendering specifically referred to the extraction of fat from animal materials through heating. However, the term has evolved to encompass the production of carcass meal, meat meal, and technical fat. While the traditional method of rendering involved boiling animal remnants to extract fat, contemporary rendering includes the heating or steaming of carcasses to produce a nearly sterilized material that retains nutrients. The animal by-products utilized in rendering consist of excess fat, hooves, and offal. In the past, tallow was employed in the manufacture of soap and candles, while other by-products like heads and hooves were repurposed for fertilizers. Meat packers quickly recognized the potential for profit in processing these by-products. Today, the rendering industry generates a variety of valuable products, including both edible and inedible oils, chemicals, meat meals, and bone meals, derived from materials such as viscera, bones, trimmings, dead stock, and feathers. A substantial portion of these by-products is recycled into useful products. In developed nations, as well as in India, integrated abattoirs and meat processing facilities manage such waste utilizing advanced equipment and sophisticated processes. Pre-rendering operations: It is essential to process raw materials from the slaughter floor swiftly and comprehensively to guarantee the highest quality of the final product. Prior to placing these materials into the cooker, they require adequate preparation. Heads, feet, condemned carcasses, and bones from the boning department are initially reduced or crushed into smaller fragments using shredders. Additionally, bones can be further reduced in size with machines referred to as “pre-breakers.” Intestines and other soft tissues, which may be
contaminated with feed or manure, must be opened, cleaned, and reduced in size before being incorporated into the cookers during the inedible rendering process.

Introduction
Teratology is the branch of veterinary embryology that studies congenital malformations, often referred to as birth defects, which arise during embryonic or fetal development. Understanding teratology is crucial for veterinarians and researchers because these defects can lead to substantial animal morbidity, mortality, and economic losses in the agricultural and livestock industries. In addition, teratological research can offer insights into human congenital disorders, given the similarities between mammalian developmental processes.
Definition and Scope of Teratology
The term “teratology” derives from the Greek word teras, meaning “monster” or “marvel,” reflecting the historical observation of grossly abnormal fetuses or neonates. Teratology focuses on the etiology (causes), pathogenesis (development), and morphological consequences of developmental disorders. These abnormalities can manifest as structural, functional, or biochemical anomalies, and they can affect a wide range of systems, including the cardiovascular, skeletal, nervous, and reproductive systems. In veterinary medicine, the study of teratogens—agents that cause developmental malformations—is critical. Teratogens include drugs, environmental chemicals, infections, radiation, and nutritional deficiencies, among others. These agents can disrupt normal embryonic or fetal development, leading to a variety of abnormalities.
Causes of Teratogenesis
Teratogenic agents can be broadly classified into several categories:
1. Genetic Factors
Genetic mutations, chromosomal abnormalities, and hereditary disorders can predispose animals to developmental defects. Genetic teratogenesis can occur due to spontaneous mutations in the DNA sequence or inheritance of defective genes from one or both parents. Chromosomal anomalies, such as duplications, deletions, or translocations of

Advancements on sugar processing

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

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