India is the largest producer of pulses and contributes around 25% of total global pulse production. In addition, it is also world’s biggest consumer (27% of world consumption) and importer (14%) of pulses in the world. Pulses account for around 20 per cent of the area under food grains and contribute around 7-10 per cent of the total food grains production in India. Though, pulses are grown in both Kharif and Rabi seasons, Rabi pulses contribute more than 60 per cent of the total production. Gram is the most dominant pulse having a share of around 40 per cent in the total production followed by tur/arhar at 15 to 20 per cent and urad and moong at around 8-10 per cent each. Madhya Pradesh, Maharashtra, Rajasthan, Uttar Pradesh and Karnataka are the top five pulses producing states in India. Considering the nutritional importance of pulses and its products in Indian diet, the production and availability are not sufficient. Since independence, grain production has grown dramatically but pulses production and its availability have declined. On the other hand, the per capita availability of cereal and millets has increased in spite of a four-fold increase in population. The consumption ratio of cereal-to-pulse has risen from 6:1 to 12:1.

Pulse processing is the major need of developing nations as it is the most acceptable and cheap source of protein and hence can help combating Protein Energy Malnutrition (PEM). In addition, the identification and recognition of various newer and improved processing methods can provide the basis for further development of legume processing industry. Traditionally, home cooking is applied for consumption of pulses since ages. Modernization has no doubt created a lot of ease and developed various techniques to make different edible forms of legumes/pulses. Many advancements have been happened in traditional processing methods (milling, fermentation, roasting, boiling, steaming etc). and resulted into new products. Improved techniques for efficient milling of legumes into dhal (dehusked splits) are an important area of investigation. A systematic method that eliminates wastes and losses has great significance in the Indian dietary pattern. New systems for processing legumes come under several main categories, namely, improved decortications and milling techniques; quick-cooking pulses; canned pulses; pulse flakes, expanded snack foods etc. Such new and innovative processing technologies presented in this chapter can be applied and used in developing nations. Present chapter will discuss both traditional and non-traditional means of pulse processing.

A management tool for anticipating the onset of diseases in plants is called plant disease forecasting. This management method makes use of data on the past, present, and predicted weather in a particular area to forecast the onset and severity of disease in the future. In this sense, a plant disease forecasting system notifies farmers ahead of time whether or not to modify their crop protection strategies to ward against pests. The disease forecasting method lowers financial costs, farmer production loss, and negative environmental effects when it is timely and precisely forecasted. These systems ought to be prepared for diseases like these, which don’t happen often but rather manifest destructively during opportune weather.

Requirements for Disease Forecasting

Systems for forecasting plant diseases are based on the “disease triangle,” which describes how the environment, host, and pathogen interact. Therefore, information on these variables is necessary for the accurate forecasting of a disease outbreak in the future. Following questions and answers cover various aspects of disease forecasting and pathometry, including their impact on integrated disease management, environmental considerations, and specific challenges in different agricultural settings.

There are many environmental risks associated with stubble burning. Thus the adoption of alternative straw management strategies is the best interest of all concerned. Key points when considering harvesting surplus cereal straw are: i) maintain sufficient crop residue on the land to protect the soil from erosion. This can be accomplished by keeping the stubble standing particularly after seeding; ii) harvest surplus crop residue with an appropriate frequency so as not to lower soil organic matter, soil fertility and crop productivity; and iii) fertilize crops according to soil test recommendations. The decision regarding the amount of straw to be removed should be based on the inherent value of the straw for maintaining the viability of the cropping system and protecting the soil resource versus the value of the straw for other uses (e.g., feed and bedding for livestock, industrial strawboard and feedstock for alternative energy forms). The value of retaining the straw on the land is difficult to determine but should be based on a number of factors such as: value of straw for soil erosion control; equivalent fertilizer value of the nutrients contained within the straw; value of the straw for building soil organic matter, soil quality, and soil tilth; and value of the straw for soil moisture conservation (Singh et al., 2003; Singh et al., 2009). At harvest, it is best to chop the straw as fine as possible and spread both the straw and chaff across in the field. A number of equipment have been developed for managing the straw in the field and discussed here.

Packing: 1. The material, which is enclosed in a stuffing box for the purpose of preventing leakage around a piston rod. 2. The act or process of inserting packing material. 3. Blocking up.

Paddy dehusker: An equipment to remove husk from paddy grain. It is also known as paddy Sheller.

Paddy separator: A machine, which is used for the separation of brown rice from the paddy brown rice mixture.

Paddy thresher, pedal operated: Equipment used for threshing of paddy crop, consisting of mainly a balanced cylinder with series of threshing teeth fixed on slats and worked by a pedal and gear drive mechanism.

ABSTRACT

Endophytes are microorganisms that live inside the host plant tissues without causing symptoms of disease. There has been a crescent interest in the prospecting of these microorganisms as sources of novel and bioactive natural products. In fact, a significant number of interesting natural products have been reported in the last years. In this chapter some aspects regarding the endophytes are detailed: the relationship with their host plants, isolation, preservation, taxonomy, cultivation, frequently isolated strains, tropical endophytes, novel structures isolated and also their biological activities.

Key words: natural product, endophytic fungi, plant fungus interaction, secondary metabolites.

Introduction

Groundnut (Arachis hypogaea L.) commonly called as Poor man’s cashew, is the 6^th most important oil seed crop in the world. It contains 48-50% oil, 26-28% protein and 11-27% carbohydrates. Groundnut is grown on 26.4 million hectare worldwide, with a total production of 37.1 million metric tons and an average productivity of 1.4 metric tons/ha. Developing countries constitute 97% of the global area and 94% of the global production of this crop (FAO, 2011). The production of groundnut is concentrated in Asia and Africa, where the crop is grown mostly by smallholder farmers under rain-fed conditions with limited inputs. Groundnuts (peanuts) are popularly used as seed oil in India. Since, they are obtained from the ground, they are called as groundnuts and also known as ‘Mungfali’ in Hindi, ‘Palleelu or Veru sanaga’ in Telugu, ‘Kadalai’ in Tamil, ‘Nilakkadala’ in Malayalam, ‘Kadale kaayi’ in Kannada, ‘Singdana’ in Gujarati and ‘Shengdaane’ in Marathi. Groundnuts are easily available round the year and almost everywhere in India. Groundnuts are also taken as snacks in many households especially in India. In reality, groundnuts are actually legumes. Since, they have all the properties of nuts like almonds, cashew nuts, etc., these are also included in the family of nuts.

Groundnut is the major oil seed of India. It accounts for 25% of total oil produced in India. Annual production of groundnut is around 9690 thousand tones. As the crop is grown in rainfed conditions, production and productivity are highly vulnerable to rainfall and exhibit huge fluctuation between the years. In India, groundnuts are produced both during Kharif (75%) and Rabi seasons (25%). Major production catchments of groundnut are located in Gujarat holding a share of 50.77% of total groundnut production, Andhra Pradesh holding a second place (12.69%) followed by Tamil Nadu (9.91%). Following are the top groundnut producing states of India (Table 1).

Introduction

Quality is the ultimate criterion of the desirability of any food product to the consumer. Overall quality depends on quantity, nutritional and other hidden attributes along with sensory quality. Sensory quality is of great importance to both processors and consumers, since it attracts consumers; it satisfies consumers’ aesthetics and gustatory sense. Sensory quality is the combination of sensory senses of perception responsible for choosing and eating a food.

According to Institute of Food Technologists and the American Society for Testing and Materials, sensory evaluation is a scientific method used to evoke measure, analyze, and explain those responses to products as perceived through different senses like sense of sight, smell, touch, taste, and hearing (Stone and Sidel, 2004). Sensory evaluation gives a general rule for the preparation and serving of samples under controlled conditions so that unfair decisions are minimized. People for sensory evaluation are often placed in individual test booths so that the judgments they give are true and do not reflect the opinions of those around them.

Samples with random numbers are given to the evaluators so that they do not form judgments based upon labels, but rather on their sensory experiences. Products may be given in different orders to each evaluator to help measure and to ensure internal validity by controlling the potential confounds created by sequence and order effects. To control unwanted variation and to improve test precision, standard procedures may be established for sample temperature, volume, and spacing in time, as needed.

Sensory evaluation or testing is a quantitative science in which numerical data are collected to establish lawful and specific relationships between product characteristics and human perception. Sensory methods draw heavily from the techniques of behavioural research in observing and quantifying human responses. For example, we can assess the proportion of times people are able to discriminate small product changes or the proportion of a group that expresses liking for one product over another. Another example is having people generate numerical responses reflecting their perception of products taste and smell.

Fishes use their sense organs to detect their bodies and their environment. Sense organs include the eyes, the lateral lines, the nostrils, the olfactory organs and the taste organs. Each of these sense organs is equipped with sensory nerve endings. Most fish possess highly developed sense organs to detect smell, sight, hearing, taste, touch, temperature, etc.

27.1 Olfaction in Fishes

27.1.1 Introduction

Saline and alkali soils occur commonly under arid climate due either to the presence of an excess of soluble sodium salts or to the predominance of sodium among the exchangeable bases.

Saline and alkali soils have been classified as follows

1. Saline soils

Saline soils were originally called “White alkali” soils. Russians term them as “Solonchak” soils.

The soils are classified as saline if the electrical conductivity of saturated soil paste is more than 4 dS /m at 25⁰C, exchangeable sodium is less than 15 percent and pH is less than 8.5.

2. Alkali soils

The soils have been classified as alkali if the electrical conductivity of saturated soil paste is less than 4 dS/m, exchangeable sodium is more than 15 percent and pH is 8.5 to 10.0.

Pen Enclosure for housing rabbits that allows for freedom of movement by rabbits and allows for the provision of a variety of environmental enrichment strategies. Cage Fully enclosed container for housing rabbits which, because of its size, restricts freedom of movement by rabbits and limits the provision of environmental enrichment strategies. Cages are usually constructed from metal or plastic, with solid or mesh sides.

There are many migratory, semi-migratory and sedentary shepherd communities in India with sheep rearing along with goats as the main livelihood)Besides scores of land less wages-earning families keep small numbers of goats for crucial supplementary income. Sheep and goat farming, due to its quicker and better returns on investment provides an additional source of income to farmers who normally depend on crops for their livelihood) Thus these animals fit in ideally in a mixed farming system. In India, goats and sheep are mostly maintained under extensive system which includes migratory, transhumance, free range, grazing community pastures, stubbles of cropped lands supplemented with crop residues and tree-lopping. Although a number of management systems are in practices varying from region to region these may be conveniently divided in to extensive, Semiintensive and Intensive systems.

Animals experience the effects of force in everyday life. For example, the animal body exerts a force on the body and to the objects during various agricultural operations. Furthermore, the gravitational force exerts continuously, for instance while sitting, walking, etc. All parts of the body in one way or the other are loaded by forces. The bones provide rigidity to the body and can sustain high loads. The skin is resistant to force. The cardiovascular system is continuously loaded dynamically owing to the pulsating blood pressure. The bladder is loaded and stretched when it fills up. The intervertebral discs serve as flexible force- transmitting media that give the spine its flexibility. Beside force, animals are using levers all the time in their daily life to increase the ‘force’ that is applied to some object.
Animal soft tissues are complex materials that can exhibit nonlinear, time dependent, inhomogeneous, and anisotropic behaviors. The mechanical responses are reflected in all levels of organism (molecules, organelle and body levels). Several biological activities are under the action of forces, which even govern the gene expression. The study dealing with the forces and their effects on living systems is the Biomechanics.
Biomechanics applies the laws and the techniques of mechanics in the study of biological systems and phenomena. Indeed, mechanics provides the tools for:

Watershed

A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. John Wesley Powell, scientist geographer, put it best when he said that a watershed is: “that area of land, a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community.”

Watershed is defined as a hydro-geological unit of area from which the rainwater drains through a single outlet. Watershed development refers to the conservation, regeneration and judicious use of all the natural resources (like land, water, plants, animals) by human beings. Watershed Management brings about the best possible balance between natural resources on the one side and human beings on the other. Human beings and the ecology are interdependent. The changes in the environment directly affect the lives of the people depending on it. A degraded environment means a degraded quality of life of the people. This degradation can be tackled effectively through the holistic development of the watershed. A watershed provides a natural geo-hydrological unit for planning any developmental initiative. The approach would be treatment from “ridge to valley”.

A watershed, also called a drainage basin or catchment area, is defined as an area in which all water flowing into it goes to a common outlet. People and livestock are the integral part of watershed and their activities affect the productive status of watersheds and vice versa. From the hydrological point of view, the different phases of hydrological cycle in a watershed are dependent on the various natural features and human activities. Watershed is not simply the hydrological unit but also socio-political-ecological entity which plays crucial role in determining food, social, and economical security and provides life support services to rural people.

Weaning foods

Introduction

Breast milk is natural and best for the growth and development of newborn babies. Although breast milk is adequate to provide an optimum nutrient till the age of six months but after that it is not sufficient to sustain optimum growth and fulfill their nutritional requirements. Various nutrients are required to supplement milk until child is ready to eat adult meal. This additional food along with the breast milk is referred as “complementary Food”. With adequate amount of complementary feeding breast-feeding continues up to two years of age and beyond so, referred as complementary feeding period.

Appropriate and adequate amount of complementary feeding helps in preventing malnutrition stunting and promoting growth. Introduction of this complementary food is called as weaning.

Weaning is the process of introducing adult food and beverage to the infant to support their growth and development. This is very crucial period in infant’s life. This is a period for diet transition as the nutrition requirements for growth and brain development is quite high. Introduction of various taste and texture promotes biting and chewing skills (Guthrie, 1975). Most six-month age children start eating semisolid foods. Weaning homogenized infant foods play a major role in the nutrition of infants (Martinez, 2004).As infants grow, their nutritional requirements also increase. To keep up this growing demand WHO recommends that infants start eating solid, semi-solid or soft foods at the age of 6 months to ensure sufficient nutrient intake.

Application of ultrasonography has become a routine practice in canine and feline medicine to detect pregnancy, to ascertain foetal wellbeing, to ascertain live/dead status of the foetus, ovarian dynamics, and to diagnose reproductive ailments (uterine, ovarian,) in females. Sonography is also being preferred in males for the diagnosis of diseases of prostate gland, cryptorchid, and testicular diseases.

Plant parasitic nematodes cause serious problems in sustained crop production. For a successful management of nematodes, their morphology, biology and host - parasitic relationship should be thoroughly studied. A thorough study is achieved only when its taxonomical position is known. Thus, in a simple way taxonomy can be defined as the theroretical study of classification of an
organism.

Organic liquid formulations (OLFs) are agricultural inputs derived from natural sources, designed for use in organic farming. These formulations, consisting of liquid solutions or suspensions containing organic compounds, nutrients, and beneficial microorganisms, play a crucial role in enhancing soil fertility, plant nutrition, and pest management, while promoting environmental sustainability and ecosystem health. Despite their eco friendly nature, OLFs demand careful consideration for their environmental impact and safety. They biodegrade readily, reducing long-term persistence and are less harmful to non-target organisms. While OLFs offer numerous benefits, they also face limitations in potency and effectiveness compared to synthetic pesticides, often requiring more frequent applications and leading to increased labor costs. Their impact can vary with pest species and environmental conditions, and they generally provide gradual rather than immediate pest control. Availability and accessibility can be limited, posing challenges for some farmers. This chapter explores the role of OLFs in achieving success in organic farming, highlighting their benefits and limitations, and emphasizing the importance of Integrated Pest Management strategies and careful consideration of various factors to optimize their use in promoting sustainable agriculture.

Abstract

The study of computational toxicity prediction is very crucial and necessary, as it is quite time consuming and expensive to measure the toxicity via experimental techniques (Quan Liao et al., 2006). The use of computational approaches particularly to reduce the time and cost for the evaluation of the kinetic and toxic behaviour of any drug has been increased tremendously in recent time period (Richard Judson et al., 2004). Machine learning is a powerful tool to discover new complex combinatorial relationships in various in vitro and in vivo data information (Richard Judson et al., 2004) and has been successfully used in many diverse fields with numerous applications such as pharmacodynamics properties prediction (Czerminski et al., 2001; Livingstone et al., 2003), protein function prediction (Cai et al., 2003), medical decision making (Veropoulos, 2001), spam categorization (Drucker et al., 1999), detection of oil spills (Kubat et al., 1998), and speech recognition (Nuttakorn et al., 2001).
