Abstract

The desert environment is one of the most challenging environments for human habitation. Inhabitants have to deal with climatic factors such as high temperature, sandstorms, flash floods and lack of water due to low rainfall. The people of Saudi Arabian desert had developed various traditional adaptation approaches such as living in tents, wearing head dresses, settling close to source of water, using camel for transportation, irrigation farming and traditional land management (hema). In recent times, modern technologies for air conditioning, transportation and housing have replaced the traditional adaptation methods especially in the cities. The modern technologies have reduced the challenges faced by the traditional society but has thrown up new challenges to sustainability. The new issues include urban flooding, depletion of underground water, high energy demand and consumption and loss of natural habitat to urbanization. This chapter reviews the traditional and the modern adaptation techniques in Saudi Arabia especially in the urban areas. It examines the implication of the changes for urban sustainability and explores different approaches for reducing the negative impacts. The chapter also dwells on the role of geospatial techniques in adapting to the desert environment.

Key Points

• With the aid of microorganisms, ruminants typically use NPN to synthesis proteins for nutritional needs.

• When there is an excess of urea in the body, ammonia is produced excessively, which can be harmful.

• The majority of clinical indicators are neurological in nature, and their severity varies depending on a number of variables.

• Ruminal environment acidification to stop excessive ammonia generation and absorption; symptomatic therapy is advised.

Introduction

In addition to being a widely utilized fertilizer for crops, urea is frequently used in animal feeds as a low-cost protein substitute [1]. The previously mentioned explanations explain the reports of urea toxicity in ruminants. These animals may use non-protein nitrogen (NPN) like urea to create ammonia, which is subsequently used to synthesize proteins that partially meet their nutritional needs. This is made possible by the urease enzyme and ruminal microorganisms. On the other hand, rapid overconsumption of NPN leads to excessive ammonia generation and toxicity. This chapter aims to provide an overview of some of the most frequent causes of urea poisoning, clinical symptoms to watch out for, and associated treatments.

(Method of Schram and Aines, 1959)

All the legume seeds and their byproducts are very rich in urease activity which may be responsible for an appreciable loss of urea nitrogen on long duration storage. Therefore it is necessary to estimate urease activity in legume seeds and their byproducts.

Reagents

    1.    Dimethyleaminobenzaldehyde solution (DMAB). Dissolve 16 g DMAB in 1 litre 95% ethyl alcohol and add 100 ml concentrated hydrochloric acid (Stable one month).
    2.    Pyrophosphate buffer. Dissolve 233 g Na4P2O7. 10H2O in approximately 980 ml distilled water. Add 3 ml of conc. Hcl and then dropwise further Hcl until the pH of the buffer is 7.7 to 7.8. Dilute to one litre.
    3.    Buffered urea solution. Dissolve 0.4 g urea in one litre pyrophosphate buffer (Stable one week).

Key Points

• The most commonly cystitis and pyelonephritis occurs in farm and companion animals after parturition.

• Hematuria, pyuria, and stranguria are common presenting clinical symptoms;

• In acute situations, a prolonged course of treatment (two to four weeks) with the administration of the proper antimicrobials is usually successful.

Introduction

Both farm animals and companion animals frequently suffer from urinary infections, which are difficult to diagnose. In cows, urine testing is more helpful in excluding the illness if it shows any pus or germs (in females), and f inding the urethral calculus that is causing the urinary obstruction can be done by palpating the bladder using a rectum examination and palpating the urethral tube (in males). Because of the shorter urethra in females and the associated uterine infection that occurs during or after parturition, females are more likely to get urinary tract infections.

The urinary organs include the kidneys, ureters, bladder and urethra (Fig. 4-5 A).

Kidneys

The kidneys are two compound tubular glands situated retroperitoneally in the sublumbar region. They are elongated, the right kidney being elliptical in outline and the left one slightly oval. They are red brown in colour. The weight of each kidney varies from 500 to 700 gm, the left kidney being about 25 gm heavier than the right kidney. The outer surface of the bovine kidneys is marked by polygonal lobes which are about twenty in number and are separated from each other by deep grooves (fissures). The grooves are filled in by fat. Both the kidneys are embedded in a large amount of perirenal fat termed as adipose capsule.

The kidneys develop from the nephrotome (intermediate mesoderm). The series of nephrotomes forms urino-genital ridge which splits up into an lateral nephric and a medial genital ridge, which project into the coelom from the dorsal wall. This is the short segment of mesoderm that connects somite with lateral mesoderm. Three sets of kidneys are formed during embryologic development in vertebrates viz., pronephros, mesonephros, and metanephros. First two sets are temporary structures and third set becomes the kidneys found in the adult.

Urinary system is relatively simple and consists of a pair of kidneys, a pair of ureters, the bladder and the urethra. The kidneys are the main organs that filter the blood and produce the urine while the rests of the organs of this system are simply accessory structures that are used for transport and storage of urine. For proper functioning of the metabolic processes of the body, it is essential to constantly maintain the chemical composition and volume of the tissue fluid. This is called the homeostasis. This particular task is performed by the urinary system and in particular by the kidneys.

Kidneys

The kidneys right and left, are bean shaped red brown relatively large glands situated in the abdominal cavity. These are placed retroperitoneal against the dorsal wall of the abdomen on either side of the spine. The right kidney is about half of its length ahead of the left kidney and it fits into the renal impression on the caudate lobe of the liver. An indentation at about the middle of the medial border is the hilus of the kidney through which pass the renal vessels, nerves and ureters. Both the kidneys are covered by a thin capsule formed of fibrous tissue which surrounds the parenchyma of the kidneys. The capsule can be easily striped away from the kidney. The function of the kidneys is to maintain the volume and composition of the plasma,regulate water, ion, and pH levels, retain nutrients and excrete fluid wastes, toxins and excess electrolytes. The kidneys achieve these functions through glomerular filtration, solute reabsorption, tubular secretion, water balance and acid-base regulation.

The renal capsule provides a stiff outer shell to maintain the shape and protect the inner soft parenchyma. Deep to the capsule is the soft, dense vascular cortex. Several cone shaped pyramids form the medulla deep to the cortex. The pyramids are aligned with their bases facing outward towards the cortex and their apices point inward towards the centre of the kidney. Each apex connects to a minor calyx, a small hollow tube that collects urine. The minor calyces merge to form three major calyces, which further merge to form the hollow renal pelvis at the centre of the kidney. The urine collected into the pelvis drains into the ureter that exits through the hilus of the kidney.

Urinnalysis An essential laboratory test that is easily conducted in veterinary settings and is included in a basic database is urinalysis. Documenting diverse urogenital tract conditions is helpful, because it could reveal details about other systemic conditions including hemolysis and liver failure. Cystocentesis, urethral catheterization, or simply voiding can all be used to collect urine. Urine should be examined within 30 minutes, but if this is not possible, it can be refrigerated for up to 24 hours or sent to a outside diagnostic lab; this, however, may cause crystal precipitation. The pH or specific gravity of urine are unaffected by refrigeration. Preservative should be added if cytologic analysis is necessary and a delay in slide preparation is anticipated. A few drops of 10% formalin (exact concentration not necessary) are better than boric acid

The uronic acid pathway is a minor and alternative pathway for glucose oxidation and for the production of uronic acid sugar. Uronic acids of sugars are formed when the terminal carbon’s (C6) hydroxyl group (CH2OH) of sugar gets oxidized to a carboxylic acid. Uronic acid names depend on the name of the parent sugars. Uronic acid of glucose is glucuronic acid, hexose uronic acids are hexuronic acids, and pentose uronic acids are named penturonic acids. The uronic acid pathway is located in the cytosol of the liver and adipose tissue.
The glucuronic acid should not be confused with gluconic acid (aldonic acid) and glucaric acid (aldaric acid or dicarboxylic acid). Gluconic acid (aldonic acid or “onic” acid) is obtained from D-glucose by oxidizing its aldehyde group at C1 to a carboxyl group. Glucaric acid (aldaric or dicarboxylic acid) is formed upon oxidation of both the terminal hydroxyl groups (C1 and C6) and the aldehyde. They have two carboxylic acid groups. This pathway yields pentoses & ascorbic acid or vitamin C (not in primates & guinea pigs) from glucose.

Bougainvilleas is a multipurpose plant due to the variation in habit, growth and colour pattern of different cultivars and are grown as pot plants, standard, hedges, bush, climber, bonsai, landscape, as an espalier, factory gardens, institutional gardens, municipal gardens, terrace garden, wind curtain, topiary, pergola and various other multipurpose. Bougainvillea in an urban landscape trained as a “standard”. It is used as an accent plant, a specimen plant, in hanging baskets, in containers, and for bonsai. Bougainvillea is used to decorate all public, home gardens, play ground and office corridor. About 300 cultivars (150 of which were bred in India) have been derived from 4 species, viz. Bougainvillea peruviana, B. glabra, B. X buttiana and B. spectabilis,through hybridization and natural or induced mutation. Indian-raised cultivars are listed in categories for growing as climbers, bushes, hedges, standards and pot plants and are also grouped under bract colour  (Nagpal 1990, Singh 1990, Singh et al. 2015, Sharma et al. 2015, Kumar et al. 2007, Mathur 2000, 2001, 2007, 2015, Richard and Erin 2002, Simon 2005). It is tolerant to a number of adverse conditions like dry soil, saline soil, pollution etc. Bougainvilleas are sprawling climbers and shrubs. They naturally bloom in the spring and seem to bloom harder in drier years. It is very good plant for desert gardens. It can be used as vines, shaped into bushes, into ground cover. Most suitable for landscaping.  Bougainvillea plants can grow easily on walls. Internode length has a strong influence on bougainvillea growth habit and characteristics in the landscape. They are pollution and drought tolerant and very ideal for landscaping of industrial region as well as for road dividers. They are very hardy plants and specially suitable for growing in rocky and arid areas where other ornamental floweing plants do not  easily thrive well (Fig. 10).

INTRODUCTION

Information has now become one of the basic needs of human being in addition to air, water, food and shelter. There is no human activity in the world without information. It is a basic raw material for right decision making from the governmental level to the personal level. It is an indispensable tool for teachers and research scholars.

Now-a-days, ICT advancements and developments have changed the libraries from mere store house of printed materials into gateways to knowledge of the world of information. The collection of modern library is not restricted to print media only but libraries are adding e-resources to their existing collections. Users need not come to library to meet their information needs. They may use online catalogue, web based database, online e-journals etc remote from library. In view of the above, information need and seeking pattern of users particularly research scholars are likely to change. Based on this, an attempt has been made to study on use pattern of electronic resources by Physics and Chemistry research scholars.

Abstract

The constant improvement in automation of bakery industry has placed higher demands on wheat. As a consequence bakery industry requires wheat possessing specific quality attributes. In view of this, there is need to produce good quality wheat not only for good chapattis but also for better bakery products viz., bread, biscuit, noodles, pasta products. New technologies are emerging which could be exploited for determining the Indian wheats for their suitability for various value added products. In the current investigation, 50 genotypes possessing low protein content (<10.5%) selected from a vast amount of breeding material were analysed for their biscuit making attributes. These lines were screened by actual baking test and alkaline water retention capacity (AWRC) test keeping the standard prescribed for biscuit making qualities viz., low protein content, low sedimentation value, low AWRC and larger diameter with larger spread factor of biscuit. Further with the help of Stable Micro Systems TA.HDi Texture Analyser the biscuits were analysed for hardness and crispness. Correlation coefficient among 8 quality traits suggested highly significant and positive correlation between sedimentation value and AWRC, biscuit diameter and spread factor, and biscuit hardness and fracturability, and significant negative correlation between biscuit diameter and its thickness. On the basis of findings, genotypes identified for biscuit making qualities may be used as donor for developing varieties suitable for biscuit making.

Different basic as well as advanced laboratory equipment need to be used in a laboratory while conducting experiments. Many of them like pH meter, laminar air-flow hood, viscometer, thermometer, magnetic stirrer, microwave ovens, incubators, sand-bath, water-bath, oil-bath, etc. are the basic and simple equipment which require to be used routinely while conducting experiments in a laboratory. However, basic knowledge of their operation, handling procedure, when to be used, how to be used, and more importantly what not to be done with it, etc. are essential for keeping them in serviceable condition as well as for the accuracy/precision in their operation. In this chapter, we will discuss about some of the routinely used laboratory equipment along, while some other sophisticated equipment will be discussed in other chapters.

pH Meter

A pH meter measures exactly the H+ concentration of a solution; thus indicates acidity or alkalinity of a solution with greater precision. Actually, it measures the difference in electrical potential between a pH electrode and a reference electrode, and display the results converted into the corresponding pH value. Electrode is the key part (rod-like structure, usually made of glass) of a pH meter, having a bulb at the bottom containing a sensor. The pH meters range from simple and inexpensive pen-like devices (portable/pocket pH meter) to complex and expensive laboratory instruments with computer interface (Figure 5.1).

Frequent calibration of a pH meter using the solutions of known pH (standard solution of pH 4.01, 7.00, 10.01, Figure 5.2), generally before each use, ensures the accuracy of the instrument. For very precise work the pH meter should be calibrated before each measurement. For normal use calibration should be performed at the beginning of each day. This is necessary because the glass electrode does not give a reproducible measurement over a longer period of time.

Introduction

To accomplish experimentations in laboratories, sometimes we need microscope to test/validate our ideas/findings. A microscope is needed to examine objects which are very small which cannot be visualised by naked eyes. However, microscopic study requires some expertise in operating the microscope, particularly the sophisticated microscopes, as well as to prepare (peeling, sections, cutting, fixation, staining, dehydration, mounting, etc.) the sample, so that it can be appropriately examined for the anticipated details.

According to the scientific requirements different types of microscopes are used in the laboratories for research purpose. In this chapter, our aim is to acquaint you with the basics of using and handling of microscopes, particularly a compound microscope that is commonly used by the graduate and post graduate students for basic research.

Microscopy is often designated as the scientific investigation that is employed to review and analyse minute structures and objects using a microscope. The term “microscope” has been derived from ancient Greek words “micros” meaning “small” and “skopeîn” meaning “to look at or see,”.

Microscope

A microscope is a laboratory instrument used to examine objects (biological specimens) which are too small to be seen by the naked eye. The microscope must accomplish three tasks:

• Magnification- to provide a magnified image of the specimen.

• Resolution- to separate the details in the image.

• Contrast- to render the details clearly visible to the eyes.

Although we will tnroduce to you the different types of microscopes used for different speciments, our main focus is to discuss about compound microscope, which is commonly used in the laboratories. Compound microscope was developed around the beginning of 17th century.

A variety of glassware like burettes, pipettes, measuring cylinders, flasks, separating funnel etc. are used for experimental purposes in a laboratory. All of these need to be used and handled correctly, otherwise the chances of experimental error and damage to the glassware increase significantly. Being made of glass, they need special care while washing and using in experiments because even a minor mistake in handling of glassware may result in breakage of the apparatus. With this precautionary note, let us discuss about some of the specific glassware used in the laboratories.

Burette

Burette is a long graduated glass tube with a stopcock at one end for delivering a known/desired volume of a liquid, especially in titration experiments. It contains a stopcock at the lower end and a tapered capillary tube as the stopcock’s outlet. The flow rate of liquid from the tub stopcock’s outlet can be controlled with the help of stopcock valve. Burette is used for measuring the volume of a solution/chemical added in a quantitative (titrimetric) estimation experiment.

Procedure of using a Burette

The burette reading must be noted before and after delivering the chemical/ solution from the burette. The difference in these two readings is the volume of the chemical/solution released out of the burette. The solution should be released slowly/drop-by-drop to avoid any experimental error/mistake. If the solution/chemical is allowed to pour out too fast, the wall of the burette will not drain properly and some liquid may remain sticking to the surface of the walls. Moreover, excessive amount of chemical may be released/dropped during the experiment, particularly during the titration experiment wherein we need to know the exact amount of acid/base needed to get neutralization point. Thus, any minor mistake may lead to get a faulty reading. The measuring capacity of a burette usually used in a laboratory is 50 mL.

Since mouth pipetting of liquid reagents in a laboratory is not advisable, different tools are needed for safe, easier, and precise dispensing of liquid reagents. This chapter is devoted to make you aware of the tools like vacupette and micropipette which can be used for the handling of liquid reagents in a safe and precise way.

Vacupette

Glass pipettes have been traditionally used by sucking liquid solvent/solution directly using mouth. For safety reasons, mouth pipetting is no longer permitted in a laboratory. Hence, to fill a pipette vacupette is used by placing it on the top of glass or plastic pipette. It acts as a device to create vacuum for filling reagent in the pipette as well as for releasing the reagent with mechanical regulation on the flow out of the liquid. Vacupette can be of different types.

1. Rubber Bulb Vacupette

Rubber bulb vacupette is often used to transfer (pump up and discharge) liquid using a pipette when a larger quantity of chemicals is to be transferred. Small/tiny rubber bulb is attached to glass/plastic pipette for drawing little amount of reagents. Small vacupette is used to precisely discharge smaller volume/ drops.

Handling of Vacupette

• Insert the top of a pipette in the bottom of the rubber bulb vacupette (Figure 6.1).

• Remove air from the pipette by squeezing valve “A” at the top of the vacupette while simultaneously squeezing the rubber bulb. The amount of air released depends on the size of the rubber bulb.

Introduction

In addition to role of iron oxidation in commercial point of view there are certain implication of iron oxidation on environment. Acid Rock Drainage (ARD) is one of the example of environmental pollution. Coal and various metal ores are enclosed in geological formation of reduced nature. Coal, is often associated with pyrite (FeS₂).When mining activities expose this material to atmospheric oxygen, a combination of auto oxidation and microbial iron and sulfur oxidation produces large amounts of acids. The iron-rich acidic mine drainage kills aquatic life and renders the contaminated stream unsuitable as a water supply or for recreational use.

Introduction

Revolutionary makeovers have happened in the fisheries, from traditional f ishing practices to the FAD and so on. However the introduction of trawlers had made a huge impact on the marine ecosystem. As trawling is made for catching the bottom dwelling shrimps, but one of the untargeted catch in trawling is Squid. As the squids gained an important role in the export market, the demand for the squids is being increasing inevitably. In response specialised fishing practices called Squid Jigging directly targeting squid resource in parallel minimised the harm on other Marine resources. The frozen and dried squids are extensively exported from the India since 1973and now it ranked fourth in terms of quantity and economic value (CMFRI). In the year 2020-22 The total f ish production of India was about 162.48 lakh tonnes in which the marine and inland sectors contributed about 41.27 and 121.21 lakh tonnes respectively (Handbook of fisheries statistics, 2022), In That the bulk of the squid landing comes from the west coast (0.28 lakh tonnes) from landed, which mostly dominated by Karnataka and from the east coast (0.12 lakh tonnes) the catch is dominated by Tamilnadu followed by Odisha. Even though a considerable amount of squid catch is obtained as the by-catch from the trawl nets, but the primary catch comes from squid jigging.

Bio-fertilizers, as the name indicates, are the fertilizers of biological origin (Gupta, 2012). In strict sense, real bio-fertilizers are green manures and organics - materials of biological origin which are added to supply plant nutrients present in them. However, in restricted scope, the term ìbio-fertilizersî or ìmicrobial inoculantsî are preparations of living organisms in alone or in combination, which may help in increasing crop productivity by way of fixing atmospheric Use of Bio-Fertilizers in Sustainable Agriculture 175 nitrogen in soils, solubilizing of insoluble plant nutrients, stimulating plant growth or decomposing of plant residues. 

What is biofertilizer?

Biofertilizers are ready to use live formulates of such beneficial microorganisms which on application to seed, root or soil mobilize the availability of nutrients by their biological activity in particular, and help build up the microflora and in turn the soil health in general.

Why should we use biofertilizers?

With the introduction of green revolution technologies the modern agriculture is getting more and more dependent upon the steady supply of synthetic inputs (mainly fertilizers), which are products of fossil fuel (coal+ petroleum). Adverse effects are being noticed due to the excessive and imbalanced use of these synthetic inputs. This situation has lead to identifying harmless inputs like biofertilizers. Use of such natural products like biofertilizers in crop cultivation will help in safeguarding the soil health and also the quality of crop products.

Abstract

Sustainable agriculture is vital in today’s world as it offers the potential to meet our agricultural needs, something that conventional agriculture fails to do. Current soil management strategies are mainly dependent on inorganic chemical fertilizers, which caused a serious threat to human health and environment. To overcome the ecological problems resulting from the loss of plant nutrients and to increase crop yields in the absence of resources for obtaining costly fertilizers, microscopic organisms that allow more efficient nutrient use or increase nutrient availability can provide sustainable solutions for the present and future agricultural practices. Microbial populations are instrumental to fundamental processes that drive stability and productivity of agro-ecosystems. Several investigations addressed at improving understanding of the diversity, dynamics and importance of soil microbial communities and their beneficial and cooperative roles in agricultural productivity. Thus the technique, which uses microscopic organism as biofertilizer, is environment friendly and ensures safe and healthy agricultural products. In this chapter we aim to provide a brief overview of potential use of biofertilizer for attaining sustainability of agro-ecosystem.

The term bio-fertilizer is related with such microorganisms that they add, conserve and mobilize the plant nutrients in the soil. Excessive use of nonrenewable exhaustive petroleum product based chemicals in horticultural production system has residual effect on soil, environment and human health. Use of biofertilizers is ecofriendly, cost effective and organic based inputs such as botanical pesticides, FYM, vermicompost, biogas slurry, disease and pest resistant varieties in cultivation of horticultural crops for safeguarding soil health and quality production.

Biofertilizers are microorganisms, which are capable of mobilizing nutrients from unavailable form to available form through biological process. They are not only cost effective but also inexpensive source of plant nutrients. They do not require non-renewable source of energy during their production. Besides, improving crop growth and quality of the product by producing plant hormones and help in sustainable crop production through maintenance of soil productivity. They are also useful as biocontrol agents, as they control many plant pathogens.

Introduction

North East India constitutes the states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura and Sikkim which reflects ecological and cultural contrasts between the hills and the plains. It is one of the most biodiversity regions in the world, with more than a hundred and fifty tribes forming a melting pot of variegated cultural mosaic of people and races constitute a vital component in this region (Dutta and Dutta, 2005).
 
More than 70% people of the region are engaged in agriculture while rice is the staple food crop (Bhattacharjee and Ray, 2010). The farmers from different ethnic diversity of the region have developed their own systems of cultivation of various crops (Islam et al. 2004). These indigenous traditional knowledge systems are quite endemic to this region (Deka et al. 2006).

Introduction

Coccidiosis is the most economically harmful disease encountered in commercial poultry production. It is caused by single celled protozoan parasites of the genus Eimeria which are commonly referred to as coccidia. Williams (1998) reported that the annual worldwide loss is about $ 800 million. The total loss due to coccidiosis is found to be Rs. 1.14 billion in India. The important finding is that almost 70 percent of the estimated cost is due to subclinical coccidiosis, by impact on weight gain and feed conversion rate. One of the reasons for these remarkable finding is probably the difficult diagnosis of subclinical coccidiosis.

Chickens are susceptible to at least seven species of Eimeria. The most common species are Eimeria tenella, which causes the caecal coccidiosis, E. necatrix &E. maxima, which causes mid intestinal coccidiosis, E. acervulina which causes anterior intestinal coccidiosis and E. brunetti which causes posterior intestinal or rectal coccidiosis. E. mitis and E. praecox are generally mildly pathogenic and commonly occurring as co-infection/mixed infection in with other species. Coccidiosis is particularly difficult to combat because several different species of Eimeria exist in the field. Poultry may become infected with different species because the immunity that develops after infection is specific only to one species. Eimeria has direct and complex life cycle that involves many developmental stages within the host cells. Each Eimeria species has characteristic intestinal lesions and type of diarrhoea (with or without blood).

Introduction

• Objective of animal diet formulations to provide a palatable ration at minimumcost to meet nutritional and energyrequirements of the animal.

• To achieve this objective, it is important to have knowledge about the requirementsof specific nutrient ingredients and the nutrient composition of feeds, which are used to formulate the animal diet.

• Diet formulation is an important aspect to meet production and financial goals in the most economical way.

• A dietis called balanced if it providesenergyto meet lactation, production and specific level of health requirement.

• Economic as well as nutritional aspects should be considered while optimisingnutrient ingredients.

• These three factors are so intimately related to each other that cannot be separated during the process of feed formulation.

Preliminary Stages

• The first step in diet formulation is to define the objective of diet formulation. Depending on the objective of diet formulation (such as reproduction, lactation, live-stocketc.), requirementsfor nutrient ingredients are established

• This step includes individual units and overall requirement for diet ingredients. After defining the objective of study and diet formulation, requirements of nutrient intake are defined to achieve that objective

• While definingtherequirement, socialenvironment, internal, external and economical conditions should be taken into consideration.Nutrient requirements can be established by the empirical method and factorial method.

• The empiricalmethodisbasedonexperimental studies whereas the factorial method identifies the various functions within the animal that defines the needs of nutrient ingredients.

India has a primarily agrarian economy. A significant portion of the country’s land is utilized for agriculture, and many of its agro-ecological regions cultivate a broad spectrum of crops. With a production of 93.9 million tons (Mt) of wheat, 104.6 Mt of rice, 21.6 Mt of maize, 20.7 Mt of millets, 357.7 Mt of sugarcane, 8.1 Mt of fibre crops, 17.2 Mt of pulses and 30.0 Mt of oilseeds crops, in the year 2011-12, it is usual that a massive amount of crop residues are produced both on-farm and off-farm. The country produces approximately 500-550 Mt of crop residues per year in the country. Therefore, landholders are facing difficulties in managing crop residues in the country. The human population has grown four times in the last century. With a projected 9.7 billion people in the world by 2050, worldwide food consumption and the demand for meat and milk are likely to increase by as much as 73% and 58%, respectively. Improved agricultural and industrial practices have contributed to the population boom, which continues to put pressure on food supply to feed a growing population. Huge quantities of food resources will be needed, but again, the crop residues produced at these levels of global production pose major challenges.

Availability of Crop Residues

India produces more than 500 million tons (Mt) of agricultural residue on an annual basis. The quantity of residue produced has grown significantly due to the cultivation of wheat and rice. Crop residue output varies greatly, and the use of these residue is influenced by the crops cultivated, the intensity of cropping, and the productivity across different Indian regions. About 70% of the total crop residues (352 Mt) are contributed by cereal crops (rice, wheat, maize, millets), with rice contributing 34% and wheat 22%. The excess agricultural residues—that is, the residues left over after subtracting the amount used for other purposes—are often burned on the farm. The amount of surplus crop residues available in India is estimated between 84 and 141 Mt per year where cereals crops contribute 58. As an estimate, about 70 MTs of surplus crop residue are burned annually.

At present, approximately 1.4 million of the world’s species are described, but  majority are still unknown to science. Plant genetic resources have gained global attention in  recent past by agricultural and environmental institutions. Conservation and use of genetic resources attracted considerable attention. Value of biological diversity in economic terms is very important for human society. India is one of the major centers of diversity in world. A small part of plant and their culture is considered as floriculture. India is bestowed with varied types of agro-climatic conditions conductive for growing a wide variety of ornamentals including flowers. India has a rich heritage of ornamental floriculture.

In rural and hilly areas there are different types of colourful flowers and foliage at different seasons round the year. All these colourful flowers and foliage are wasted under natural process. In spite of aesthetic beauty, all these natural resources are totally unutilized due to unawareness of their use. All these flowers are available in wide range of colours but mostly dominated by yellow. The entire seasonal colourful vegetations can be converted into value added products by using simple dehydration technique developed at National Botanical Research Institute, Lucknow. The technique is  suitable for dehydration of flowers and foliage. Present chapter will highlight how dehydration techniques can be utilized for preparation of value added products from seasonal unutilized floral vegetation of rural India.

Introduction 
Natural product scaffolds and heterocyclic ring-based organic compounds are crucial for developing bioactive substances and therapeutic drugs, serving as essential structural units for bioactive molecules and pharmacophores. Numerous experts have worked hard to design and develop organic synthesis, which could make it easier to obtain these crucial organic chemicals. Due to the multistep reactions involving several hazardous chemicals, conventional organic synthesis is neither commercially feasible nor environmentally benign. To overcome these issues, improvisation or developing a new synthetic approach with a superior atom and step economic procedure is always desirable. The biggest challenge in organic synthesis is functionalizing a carbon-hydrogen (C-H) bond in a molecule. This is generally achieved through radical intermediates and catalysis by enzymes or transition metals. The transition metal-catalyzed process is the most popular due to its high chemoselectivity, site-selectivity, and efficiency (Yamaguchi et al., 2012). Inert C-H bonds can be directly functionalized, offering appealing synthetic strategies that enhance both atom and step economy and provide an overall efficiency of multistep synthetic sequences, leading to a sustainable and greener approach. These optimizations provide atom and step-economical methods for synthesizing structurally complicated organic molecules with broad substrate scope and good to exceptional product yields (Ackermann, 2011; Gensch et al., 2016). Direct conversion from the substrate to the desired organic compound without pre-functionalization is attractive and cost-effective. However, it can be quite challenging to selectively functionalize particular C-H bonds due to the inertness of those C-H bonds having similar electronic and bonding properties and the ubiquity of C-H bonds in organic molecules (Sambiagio et al., 2018). Two main techniques have been explored to obtain selectivity in C-H bond functionalization (Brückl et al., 2012). The first is based only on the natural reactivity pattern of an organic molecule. This strategy is highly successful for some heterocycles with at least one specific reactive site due to the presence of heteroatoms. However, it produces inadequate selectivity for most aliphatic and aromatic hydrocarbons. The latter is to direct further functionalization at a particular site using directing groups already present in the molecule (Kuhl et al., 2012). The development of directing groups that effectively control the regioselectivity of C-H functionalization has lately transformed this field, enabling the incorporation of desired groups in unfunctionalized sites (Docherty et al., 2023; Labinger & Bercaw, 2002). Employing directing groups, various functional groups are added to a molecule using this method. Directing groups are crucial for breaking a C-H bond in a transition metal catalysis reaction, where the metal center in the active catalyst complex is usually coordinated with the substrate through a weak interaction with the nearby C-H bond. This interaction is typically not selective; thus, the metal centre may activate numerous C-H bonds on the substrate. However, when a directing group is incorporated into a substrate, the metal center can interact more strongly and regioselectively with a specific region on the substrate as directed by the directing group.

With the perception that antibiotics should no longer be used as animal growth promoters, there has been widespread interest in natural methods of inhibiting detrimental bacteria. Their removal from the poultry diets is therefore brings with it consequences. This has lead to somewhat of a renaissance in research activity on the discovery and application of non antibiotic chemical compounds capable of either killing microorganisms outright or at the very least retarding growth sufficiently to limit their dissemination. Organic acids have a long history of being utilized as food additives and preservatives for preventing food deterioration and extending the shelf life of perishable food ingredients. In recent past organic acids have been used to control microbial contamination and replace antibiotic growth promoters in poultry (Ricke, 2003; Hassan et al.,2010; Adil et al., 2011).

Digital libraries are a set of electronic resources and associated technical capabilities for creating, searching, and using Information; they are an extension and enhancement of information storage and retrieval systems that manipulate digital data in any medium. The content of digital libraries includes data and metadata. Digital libraries are constructed, Collected, and organized by a community of users and their functional capabilities support the information needs and uses of that community.

A digital library is a library in which collections are stored in digital formats and accessible by computers. The digital content may be stored locally, or accessed remotely via computer networks. A digital library is a type of information retrieval system. Man is a communicator of information, not simply a user of tools. The history of civilization is the history of improved means of communication. Man always desires to improve the means of communicating. Documents are the artifacts of recorded knowledge that is information. Documents are meant for communication knowledge to larger audiences. Libraries have stored and served the documents to the users.

Thus, libraries have performed as one of the links between generators of information and its users. The developments of libraries from print paper based libraries to digital libraries seem an illustration of man’s never-ending desire to improve his means of communication. In the digital world highway, there is stress on three factors (a) Awareness of information: it provides breadth of vision (b) awareness of technology: gives the power to make the visions manifest, and (c) awareness of needs facilitates the insight to use professional skills and talents to greater effect.

Abstract
Aquatic weeds, such as duckweed, present a dual challenge and opportunity within aquatic ecosystems and the poultry feed industry. These fast-growing plants, often deemed nuisances due to their potential to disrupt ecosystems, offer significant potential as alternative feed sources. Duckweed, a floating aquatic plant, is particularly noteworthy due to its high protein content, rapid growth rate, and nutrient recycling capabilities. In freshwater systems, excessive growth of aquatic weeds can lead to decreased ecosystem productivity, hypoxia, and anoxia, making effective management crucial. However, duckweed’s ability to thrive in nutrient-rich conditions and its high nutritional value, including substantial protein and essential vitamins, position it as a valuable feed ingredient for poultry. The Indian poultry sector, growing at an annual rate of 8-10%, faces challenges such as rising feed costs and limited availability of conventional feed ingredients. Integrating duckweed into poultry diets can provide a cost-effective, sustainable alternative that reduces reliance on traditional feed sources and supports ecosystem management. This approach not only addresses feed shortages but also contributes to environmental sustainability by recycling nutrients and mitigating pollution. Despite its potential, challenges such as lack of standardized regulations and market acceptance remain. Continued research, policy support, and market promotion are essential to harness the full benefits of aquatic weeds.

1. Introduction

Electronic journals are an important source for scientific technical research and development. This resource is widely used by research and development workers and other users of the libraries to carry out qualitative research, education and gain knowledge. In recent years there has been a surge in the number of electronic journals available to libraries for their users to access. More titles are made available by publishers and subscription agents. There is a common view amongst Liberians that libraries are forsaking traditional print resources in favor of electronic resources. With the application of information technology, particularly internet, there has been a shift from traditional print journal to electronic journals. This type of use survey is essential to improve the existing library services, to plan new services, rationalize the use of the limited financial resources in an economic way, evaluate the performance of the library and enhance the user satisfaction.

Abstract

Ectomycorrhizal symbionts are important natural resources to revive degraded and deforested areas. Artificial inoculum of these mycobionts improves the growth of tree seedlings in nutrient poor soils due to the formation of extensive network of fungal mycelium responsible for the transfer of water and nutrients to the plants. Seedlings of tree species like, Pinus insularis, Quercus griffithii and Schima wallichii with ectomycorrhizae formed by Suillus bovinus, Boletus edulis and Scleroderma citrinum were studied in field condition. The study was conducted at two different stages of degraded sites. Results of the study indicated that seedlings with ectomycorrhizae were able to generate numerous lateral roots of greater length and thereby utilize water and nutrients more effectively than non- mycorrhizal ones The degree of mycorrhizal development varied in different host species with different fungal species. There was a strong relation between the colonization by mycorrhiza and the survival of seedlings. The study has suggested that mycorrhiza has a potential in reclamation of soil and reforestation of degraded land. S. bovinus., B. edulis and S. citrinum successfully colonized and promoted the growth of P. insulates Q. griffithii and S. wallichii respectively in reforestation programmes of degraded lands of Nagaland.

1. Introduction
 
Today we are living in the Era of Information. Over last decade, electronic resources have become increasingly substantial components of academic library collection. This is due to the continuous development of Information Technology and its impact on library collection development policies due to changing demand of users for the pin pointed and exhaustive information within a short time. With the growing popularity of e-resources, the traditional libraries are gradually migrating from print documents to e- resources where providing access to information is considered more important than owning it. This is further augmented by the advent of Internet. Which has opened up windows of opportunity to different Information sources.

Essential oil obtained from aromatic plants is a mixture of several naturally arising biochemical compounds that occur in some plants which have scented flowers, leaves, bark, seeds, stem wood, or roots. As per the
biochemical view, the active ingredients of essential oils are tranquil of oxygenated hydrocarbons and several other types of hydrocarbons which may be clustered conferring to their biochemical structure into esters, terpenes, aldehydes, alcohols, phenols and ketones etc. Carbon is considered as the basic element for all kinds of essential oils. Majority of essential oil compounds are made of C, H, O, N and S atoms. The atom of these different kind of elements are joined to each other to make the essentia oil molecules. These biomolecules are made up of five carbon atoms is named isoprene. All essential oil compounds mainly consist terpenic compounds having two or more than two isoprene units (C5). These Isoprene units (C5) are generally attached to each other in head to tail fashion, hence ‘isoprene rule’ is followed. When two units of isoprene (10 C) are joint together, they form what is known as monoterpenes. Likewise, when three, four, five, six and eight units are united, they are called sesquiterpenes, diterpenes, sesterterpenes, triterpenes and tetraterpenes, respectively. These terpenes are colourless liquids and are generally lighter than water. They are highly refractive and insoluble in water. The ‘terpene’ term is usually restricted to hydrocarbon but on addition of oxygen in it, these are called terpenoids. These include menthol, cirtral, linalool, geraniol, carotenes, camphor, thymol, menthone etc. (Maheshwari, 1995).
Generally, the essential oil is extracted from aromatic plants through various methods but for production of essential oil for aromatherapy, the only suitable methods are those that are non-toxic. This contains cold pressing, distillation, and, in some cases, extraction by using the non-toxic solvents.

Major field operations for horticultural crops viz., fruit nursery/seedling preparation, post hole digging for planting, intercultural operation, aeration, training and pruning, irrigation, plant protection, harvesting, handling, packaging transport are completed through field tools and implements. The cultivation of horticultural crops is predominantly dependent upon human labour, since commercial cultivation is only on a limited scale. So animal/power tiller or tractor-drawn mould board ploughs, disc ploughs, harrows, cultivators and rotavators are available for land preparation and development of new orchards. The fruit plants are generally perennial plants. So different types of sprayers and dusters are available from manually to power operated such as knapsack sprayers foot operated sprayers, power operated mist blowers and dusters or plant protection equipments used for application of insecticides, pesticides and herbicides in the fruit orchards. Some of important implements and sprayers are enlisted below

Introduction

Food ingredients sector is indicating ample prospects for growth. The segment is an obligatory element for the growth of the food and beverage sector. These ingredients are also driving the development of the healthy functional foods industry to increase by 20% growth annually. Innovation in the food and beverage market, especially in the processed food domain, has created innumerable opportunities for new product development in the ingredients market as well. The segment is driven by the growing food processing industry and India is emerging as ingredients bowl of the future. Additionally, growing urbanization coupled with industrialization and changing lifestyles have led to growing demand for convenient food that offers health benefits, over and above the basic nutritional benefits of the foodstuff. There are nearly 10 to 15 broad classes of ingredients that include the very basic ingredients as well as certain value added ingredients that have niche applications. Key ingredients are preservatives, flavours, colours, hydrocolloids/stabilizers, emulsifiers, artificial sweeteners and value added health food ingredients such as omega-3-fatty acids prebiotics, probiotics etc. Until recently, there has been limited research into functional foods in meats, while functional foods in the dairy sector have been developed to a high degree. But meat is less allergenic than many other foods and much more research into the development and marketing of novel functional meat products is required. Such meat products would open up a new market for the meat industry. Nutraceutical and functional food industry is a very vibrant industry today with the claims and a clear mandate of health, wellness and prevention of diseases as one of its main goals.

INTRODUCTION

The evolution of National Natural Resource Management System (NNRMS) towards fully harnessing the potentials of space remote sensing and the development of the series of Indian Remote Sensing Satellites, besides establishment of necessary ground based data establishment of necessary ground based data reception processing and dissemination systems as well as remote sensing facilities at National Remote Sensing Centre (NRSC), Space Applications Centre (SAC) and Regional Remote Sensing Service Centers (RRSSCs) for efficient and effective analysis of remotely sensed data are the major steps accomplished in pursuit of this goal. With the establishment of Remote Sensing Applications Centers in several States under many Governmental organizations, remote sensing today has come to stay as an integral part of the national development efforts in the vital sectors of agriculture, hydrology, geology, forestry, oceanography, mineral resources and disaster management like drought, flood, cyclone, earthquake, landslides crop pests, forest fires etc., thus touching every facet of national development. Today, India has acquired a strong self-reliant base to harness the full potential of this technology and as a result, the national objective of achieving sustainable development at micro level is being addressed through the integration of remotely sensed data with other relevant collateral information to arrive at locale specific, environment friendly, economically viable and culturally acceptable treatment packages (Rao, 1991 and Jayaraman, el at. 1993).

Abstract

Aquifers are usually composed of permeable layers that can ways a considerable amount of groundwater. Usually, aquifer units are correlated through the concept of lithostratigraphy. For low-permeable aquifers, it is difficult to define the spatial distribution of hydrogeological units, and this study attempts to use geochemical methods to identify the groundwater flow paths in an area of Southeast coast of Tamil Nadu, India. Multiple geochemical analyses, including groundwater chemistry; stable isotopic compositions of d¹⁸O and 8D contents were performed.  Spatial distribution of d¹⁸O, dD, Cl-/HCO-₃ show that northeastern part of the study area seriously affected by seawater intrusion. The highly permeable aquifers at the east coastal region are characterized by high hydraulic conductivity as compared with other regions of the study area. Hydrogeochemical characteristics based on bivariate diagrams of major and minor ions show that changes in the chemical composition of groundwater are mainly controlled by the salinization process followed by cation-exchange reactions.

Abstract

The weather or climate is a natural resource and is an important basic input in agricultural planning and strategies. Every plant process, related with growth, development and yield of a crop and each of inseason and off-season farm operations (according to World Meteorological Organization) is more than 10 per cent and can reach up to 50 per cent in smaller areas and not a surprise even if it reaches to 100 per cent on micro scale. Amongst the various weather elements, temperatures, radiation and rainfall play major role in deciding the crop growth and yield levels. Precipitation is one of the important weather factors being responsible for atmospheric and soil moisture and therefore has more agricultural importance, especially in rainfed agriculture.

1.0 Introduction

India receives more than 70 per cent of its annual rainfall during South West monsoon season. Indian summer monsoon rainfall shows large intra - seasonal and intra-annual variability (Parthasarathy, 1960; Alexander et al., 1978; Mooley and Parthasarathy, 1984) and also changes in space and time, intensity and distribution. Borgaonkar and Pant (2001) have reported that Indian monsoon rainfall has shown trend less nature since 17^th century based on proxy data with large inter-annual fluctuations. IPCC (2001) has reported increase in rainfall over tropical and higher latitudes and decrease in rainfall over subtropics and mid latitudes.

While the fourth agricultural revolution has been sparked by technological advancements, humans still face many challenges in achieving agricultural resilience to meet the demands of the world’s expanding population, including declining croplands, depleting water supplies, the negative effects of climate change, and more. On the one hand, food and dairy products are in increasing demand due to the growing population. On the other hand, an increasing number of variables pose a threat to food security and sustainable food production, including globalization, climate change, scarce land and water resources, unsustainable land management techniques, pests and diseases becoming resistant to chemical pesticides, and the emergence of pathogens that have adapted to new hosts. The integration of geographic information systems (GIS), remote sensing, and artificial intelligence (AI) in geospatial approaches offers a solid foundation for the sustainable management of agricultural resources with the goal of boosting agricultural output. These days, local, regional, and worldwide agricultural production uses these sophisticated instruments more and more. Growers have been more interested in implementing precision agriculture during the past ten years. Precision agriculture is a crop-management method that takes into account the temporal and geographical heterogeneity of soil and crops within a field. Another agricultural technique that is being promoted as a future development that will enable the world’s population to be fed sustainably is precision agriculture. The broad use of geographic methods for agricultural resource management, including crop disease monitoring and pest infestation control, is the main topic of this chapter.

Grape (Vitis vinifera L.) is one of the most valuable and popular fruit crops all over the world (Mohsen, 2021). In India, grapes are mainly grown for table, raisin and wine making. Major grape producing countries are China, Italy, France, Spain, USA, Turkey, and India while, major wine producing countries are France, Italy, Spain, and USA (OIV, 2024). According to an estimate, grapevine is spread on an area of 1.71 lakh ha and production was 37.81 lakh MT in the country during the year 2023-24 (NHB, 2024). India ranks first in world for grape productivity and 7th for grape production during 2023-24 (APEDA, 2024).
Traditionally, grapes are grown on their own roots. However, due to deteriorating soil and water conditions, the use of rootstocks has become essential in the tropical climate of India to maintain production (Singh and Sharma, 2005). The grape industry which is important to produce wine and table grapes is facing  significant challenges due to changing climatic conditions. Climate change has led to increased temperatures, altered precipitation patterns, and more frequent extreme weather events, all of which can adversely affect grapevine health and productivity. To combat, the role of grape rootstocks has become increasingly vital for maintaining sustainable viticulture. Grape rootstocks are the belowgraft joint part of the grapevine onto which the scion variety is grafted. These rootstocks are typically derived from species of Vitis genus other than Vitis vinifera, the primary species used for grape production.

The plant growth regulators are the organic compounds other than the nutrients, which accelerate, inhibit or modify the various physiological processes in the plant system, when applied at low concentration. These growth regulators are readily absorbed and move rapidly in the tissues, when applied to the plant system and regulate its life processes in some beneficial ways to enhance the yield and improve the quality of the fruits.

The word hormone is derived from Greek, meaning set in motion. The five major phytohormones are auxins (indole-3-acetic acid and its derivatives), gibberellins, cytokinins, abscisic acid and ethylene. The key difference between plant hormones and plant growth regulators is that plant hormones are natural, while plant growth regulators are artificially synthesized and are applied to plants. Plant hormones are also called phytohormones. Plant hormones are the organic chemicals, which are synthesized by plants themselves naturally during the metabolic processes.These are synthesized at the given site and translocated to the site of action.

1. Introduction
In the realm of modern agriculture, achieving sustainability is paramount. The judicious use of resources and the maintenance of soil and crop health are vital components of this endeavor. Remote sensing is a powerful technique used to gather information about the Earth’s atmosphere and surface without direct physical contact (Lillesand et al., 2015). It involves the acquisition, measurement, and analysis of data from sensors aboard platforms such as satellites, airplanes, drones, or ground-based instruments. These sensors record electromagnetic radiation, providing valuable insights into various aspects of the Earth’s environment. Remote sensing technology has emerged as an invaluable tool for achieving these objectives, offering a range of benefits for sustainable agriculture (Jensen, 2009). With the advent of modern technologies such as hyperspectral remote sensing (HRS) that collects information in narrow contiguous bands, many new avenues of applications have come up. This detailed spectral information enables the precise identification and classification of objects based on their unique spectral signatures. Further, the narrow spectral reflectance provides significant information regarding the biophysical, biochemical, and physiological parameters of crops. These characteristics of HRS provides opportunities for improved feature identification, anomaly detection, and quantification. Often HRS data also complement to the remote sensing data, such as LiDAR or SAR (Synthetic Aperture Radar), allowing for a more comprehensive understanding of the Earth’s surface and its features. All these features of HRS enables precision agriculture, allowing the management practices as per the specific needs of the fields. By assessing soil and crop conditions remotely, one can apply resources like water, fertilizers, and pesticides precisely where and when they are needed. This minimizes waste and reduces the environmental impact of agricultural operations. Hyperspectral remote sensing can also assess critical soil parameters such as moisture content, pH levels, and nutrient concentrations. Monitoring these factors over time helps farmers make informed decisions about soil management and the choice of suitable crops. It also aids in preventing soil degradation and erosion. Early detection of stressors like pests, diseases, and nutrient deficiencies is crucial for maintaining crop health and maximizing yields. Remote sensing provides a timely and accurate means of monitoring crop conditions across large areas, enabling rapid responses to threats and reducing yield losses. In regions with water scarcity, efficient water management is essential. Remote sensing can track soil moisture levels and assess irrigation needs. By optimizing irrigation practices, farmers can conserve water resources while maintaining crop productivity. Remote sensing, particularly hyperspectral remote sensing can detect changes in

Principle of ICP Optical Emission Spectrometry

The ICP is a partially ionized gas (mostly Ar) plasma produced in a quartz torch using a 1–2.5 kW radio frequency power supply. Samples are typically introduced into the center of the plasma as aerosols. Compared to the atomic absorption spectrophotometers, in which the excitation temperature of the air acetylene flame measures 2000–3000 “K, the excitation temperature of the argon ICP is 7000–10,000 K, which efficiently excites many elements. The solution for analysis is carried by a peristaltic pump through a nebulizer into a spray chamber, where aerosol is produced by the argon gas. The aerosol thus generated is directed into the central channel of the plasma. The plasma in ICP is generated at the end of a quartz torch by a water-cooled induction coil through which a high-frequency alternate current flows. Consequently, an alternate magnetic field is induced, which accelerates electrons into a circular trajectory. Due to the collision between the argon atoms and the electrons, ionization occurs, giving rise to stable plasma. At the core of argon plasma, the temperature is sustained at approximately 10,000 K, where aerosols are quickly vaporized. Subsequently, atomization and ionization of the sample analyte elements take place. Due to the thermic energy taken up by the electrons, they reach a higher “excited” state. When the electrons drop back to ground level, energy is liberated as light (photons). Each element has its own characteristic emission spectrum. By means of an Echelle grating, a prism, and a focusing mirror, these emitted photons at various frequencies are captured simultaneously by the suitable detectors. The wavelength of the photons can be used to identify the elements from which they originate.
