The Indian Council of Agricultural Research (ICAR) has contributed a lot towards strengthening of Agricultural Libraries via modern Information Technological (IT) tools. ICAR has sanctioned so many projects under National Agricultural Technology Project and National Agricultural Innovative Projects i.e e-Granth, CeRA, Krishiprabha, Krishikosh Agricat etc. for strengthening and development of agricultural libraries. These are useful to manage knowledge explosion and helpful in libraries to providing information effectively to the end user of society.

Abstract

Peri-urban horticulture is fast catching on as a viable business proposition. Participation of women is envisaged as a significant input in such an enterprise. Tissue culture propagation or ‘’Micro propagation’ is a good candidate in this context among several biotechnologies available today. Micro propagation as a means of rapidly multiplying plants in a relatively small space irrespective of the season of the year has steadily gained popularity. Planting material in horticultural crops like banana and several other vegetatively propagated crops like ornamentals is in perpetual demand and can be met economically if women launched micro propagation as a peri-urban cottage industry. As against low rates of multiplication with conventional technologies, it is possible to raise thousands of propagules from a single starter-culture in a year’s time using newer technologies. Details of setting up the industry on a home-scale and participation of women in peri-urban areas in this enterprise are discussed in this plenary talk.

Plant propagation: Plant propagation means multiplication of plant by sexual or asexual method.

There are two type of plant propagation

1.    Sexual propagation

2.    Asexual propagation 

A. Sexual propagation: Sexual propagation means multiplication of the plant by seed. It is also known as seed propagation.

Advantages of sexual propagation

1.    This is the easier and cheaper method.

2.    Some of the plant does not response well by asexual method (Papaya) this type of plant only propagated by sexual propagation.

3.    Sexually raised plant are long lived have extensive root system and bear heavily as compare to asexually propagated plants.

4.    Hybrid can develop only by seed propagation.

5.    Seed can be store for longer duration.

1. Introduction

Cumin (Cuminum cyminum L.) crop belongs to the family Apiaceae and having diploid chromosome number 2n =14. It is also known as Jeera in Hindi. This crop is originated from Mediterranean region. It is an erect or sub erect, glabrous annual herb which grows to a height of 30-50cm. The leaves are alternate, compound and green, the blade consists of three slender filiform leaflets. The inflorescence is a compound umbel with white or pinkish flowers (Verma et al., 2018a). The typical pleasant aroma of the seeds is due to their essential oil and the main constituent in essential oil is cuminaldehyde. It is mainly cultivated in arid and semi arid parts of Gujarat and Rajasthan. The total area is about 12 lakh hectare with the production of about 8.5 lakh tons and total export of cumin is worth of more than Rs. 4200 crore during 2020-21 (Fig. 1 & 2). 

Fishes are generally unisexual and reproduce by several methods. Some families (Sparidae and Serranidae) are hermaphrodite also. Alz (1964) reported that in certain species, hermaphrodism becomes a normal way of life. In hermaphroditic f ishes, self-fertilisation is a common process. Parthenogenesis could have been produced experimentally (Austin and Walton 1960). There maybe a few secondary organs that increase reproductive fitness. The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm are released; the sex of a fish can often be determined by the shape of its papilla.

Last few decades have witnessed an increasing number of pets attending clinics/hospitals for cardiac care because of changed life style of owners as well as pets, more awareness of the owners and an increase in number of veterinary medical specialist with better diagnostic facilities. Cardiac failure and cardiac arrest are the two important outcome of cardiac diseases with variable treatment result. Heart functioning is affected not only in primary diseases of heart but also in diseases of organs other than the heart. Without correct diagnosis of cardiac abnormalities, treatment may be futile with a fatal outcome. Nowadays diagnosis of cardiac abnormalities is facilitated with the aid of modern diagnostic technology.

Abstract
Grain legumes face significant biotic stresses fromvarious pests and pathogens, leading to substantial yield losses worldwide. This chapter synthesizes recent advances in molecular approaches and biotechnological tools for developing resistant varieties and managing diseases in legumebased cropping systems. Novel genomic technologies, including CRISPRCas9 gene editing, marker-assisted selection (MAS), and next-generation sequencing (NGS), have revolutionized our understanding of host-pathogen interactions and accelerated the development of resistant cultivars. RNA interference (RNAi) technology has emerged as a promising tool for targeted pest control, while transcriptomics and proteomics approaches have helped identify key resistance genes and defense-related proteins. Integration of these molecular tools with traditional breeding programs has resulted in improved varieties with enhanced resistance to major pests like pod borers and diseases such as fusarium wilt and ascochyta blight. Additionally, biotechnological applications including biopesticides and disease-forecasting systems have strengthened integrated pest management strategies. This review highlights the potential of combining multiple molecular approaches for sustainable pest and disease management in legume cultivation while identifying future research directions and challenges in their widespread adoption.

Let‘s dive deeper into the processes of condensation and explore each in more detail:
• Adiabatic Processes: Adiabatic cooling occurs when air rises and expands, reducing its temperature (Fig. 9.1). This process can lead to condensation and cloud formation. There are several ways air can rise and cool adiabatically:
• Orographic Lift: When air is forced to rise over a mountain or hill, it cools, and condensation occurs, resulting in clouds and precipitation. This is why mountainous regions often experience more rainfall than surrounding are as.
• Frontal Lift: When two air masses with different temperatures and humidity levels meet, the warmer air is forced to rise, cool,
and condense, forming clouds and precipitation. This can lead to significant weather changes, such as the formation of fronts and lowpressure systems.
• Convection: When the sun heats the ground, it warms the air closest to the surface, causing it to rise and cool, leading to condensation and cloud formation. This process can lead to the development of cumulus clouds, thunderstorms, and other types of convective weather.

The stability of agriculture all over the planet and the accessibility of food are both signi?cantly affected by Climate change. Thus, it is desperately important to create and execute Climate -resilient farming techniques and advancements that can help farmers in acclimating to the e?ects of Climate change. It should be finished right away. It examines the issues welcomed on by Climate change, fundamentals of sustainable agriculture, and the instruments and strategies that can be utilized to expand farming’s protection from Climate change. This part essentially talks about Climate -friendly creature farming, viable water system frameworks, weather conditions checking and determining, crops that can endure dry spell and flooding, coordinated bug control, and sustainable power sources. To make sustainable more Climate change-safe, this part additionally talks about the need to empower feasible land-use rehearses and to make innovative work ventures. By using these innovation and methods, farmer might add to the maintainability and versatility of the food framework.
As a result of increasing temperatures and diminishing precipitation because of Climate change, farming is enduring enormously all over the planet. This is especially evident in India, where the greater part of the populace is utilized in farming. The effect of Climate change is perhaps of the main issue the world is at present encountering. The impacts of Climate change are felt and found in each part of society, including farming. Utilizing harmless to the ecosystem circular agriculture is critical now like never before as the total populace develops. One of these strategies is farming that is circular agriculture (CRA). Its central goal is to adjust cultivating practices to an evolving environment. Consistently, new people enter the earth. To take care of the growing populace, the land is feeling the squeeze to give more food, fiber, and fuel. Consistently, new people are brought into the world. Thus, the land is feeling the squeeze to create more food, fiber, and fuel to take care of the populace that is extending. As well as expanding crop efficiency, more Climate tough agricultural methods would likewise work on the soundness of the dirt and the biological system

Efficient horticultural production depends greatly on appropriate tools, implements, and timely cultural operations. This chapter introduces the major equipment used for land preparation, planting, weeding, pruning, propagation, irrigation, harvesting, and routine crop management. It emphasizes correct tool selection according to crop, operation, plant structure, and working conditions. Digging tools, secateurs, loppers, pruning saws, grafting knives, and other specialized implements are discussed along with principles of maintenance, sharpening, sterilization, and safe handling. The chapter also explains important cultural operations that influence crop establishment and productivity. Proper use of tools improves precision, reduces labour, prevents plant injury, and increases operational efficiency in horticultural systems.

13.1 Introduction

In 1935 Prof. Ronald A. Fisher laid the foundation for the subject in his monumental work entitled “The Designs of Experiments”. Experimental designs concern the arranging of treatments or variables in such a manner that the inferences and conclusions regarding the effects of these treatments can be easily done and their reliability measured. Experiments are made with a view to find the validity of a particular hypothesis and to have an idea about the extent of the reliability that can be placed on a particular conclusion arrived. The selection of the design will have a very great bearing on the accuracy of the ultimate results. By a random selection of experimental units it is possible to remove the ambiguity about the casual interpretation of the observed associations. Random sampling is the most essential ingredient of all experimental designs. Besides, there are many devices for increasing the precision of the inference and the calculations.

INTRODUCTION

In biology, fertility is de?ned as capacity to produce off-springs; however, in Soil Science a ?ne difference is made between a fertile and a productive soil. Soil Productivity is the ability of a soil to produce a crop using the entire spectrum of its physical, chemical and biological attributes, while Soil Fertility refers to the capacity of a soil to supply all essential plant nutrients in the desired amounts. Thus, soil fertility management is basically the nutrient management. To put it in simple words, a productive soil is always fertile, while a fertile soil may not be productive for a variety of factors, such as lack of adequate moisture in drier regions or lack of adequate air due to water-logging for most upland crops. Of late, a term ‘ Soil Health’ has been introduced. Soil Health is an assemblage of chemical, physical and biological parameters that closely relate to native or acquired production capacity and sustenance of ecologically important regulatory role (Katyal et al., 2016). It is measured against prede?ned parameters of soil’s status of fertility, compact ability, erodibility and biology. This again tends to relate soil fertility to nutrient content, availability and management.

Introduction Solid–liquid extraction process, has been extensively used for extraction of bioactive compounds from plant food matrices by using appropriate solvent, which can be used as functional ingredients and additives in food processing, pharmaceutical sectors, and others industries. Usually this extraction/recovery process is based on unsteady diffusion of compounds targeted for extraction, through the matrices followed by the dissolution of the extractable compounds in the bulk of the used solvent (Milic, Rajkovic, Stamenkovic, & Veljkovic, 2013). The concentrations of bioactive compounds in food matrices as well as in the extracts are generally low in percent, so extra energies are required to improve the yield of the extraction process while minimizing the overall cost. From the technological approach, extraction process is mainly associated with the operating variables such as solvent used, extraction technique, operating temperature, concentration of solid in solvent, and extraction time, and by optimizing these parameters extraction yield could be enhanced (Milic et al., 2013; Orphanides, Goulas, & Gekas, 2014).

Diseases of gastro-intestinal tract are very common in dogs and cats. Gastro intestinal tract starts from mouth to anus. The first step in making diagnosis of gastro-intestinal disease is to localize the problem. Whether it is buccal cavity, esophagus, stomach, or intestines. Cursory history for seemingly simple complaint like vomiting, anorexia or loose feces may be unrewarding because gastrointestinal diseases may be primary (concerning with only gastro intestinal tract and its functions) or secondary (due to underlying disease/ disorder of organs other than gastro-intestinal tract). Therefore, for ascertaining the cause of gastrointestinal signs (anorexia, nausea, vomiting, regurgitation, constipation, loose feces, bloody feces), a thorough examination of all body systems is more logical. As with other body systems, a comprehensive systematic approach is needed for diagnosing diseases of gastro-intestinal tract also.

Agriculture constitutes the primary source of income in rural India. Rural women play a pivotal role in various agricultural practices, encompassing activities such as planting, harvesting, and post-harvesting operations. Additionally, their responsibilities extend to producing agricultural crops, tending to animals, processing and preparing food, engaging in wage labor within agricultural or other rural enterprises, collecting fuel and water, participating in trade and marketing, caring for family members, and maintaining their homes (Klasen and Lamanna, 2009).

The engagement of rural women in agriculture is extensive and multifaceted, covering a wide range of activities that are vital for household sustenance and community welfare. These activities are essential not only for economic stability but also for food security and overall rural development.

Introduction

The term "artificial intelligence" was originally coined in 1956 at a conference hosted by Dartmouth College. While the aspirations and dreams of the attendees were sky-high, the reality was sobering. The thought of citizens in space or self-driving cars within a decade was ancient science fiction. The building blocks of the required computing infrastructure, as well as AI, notably deep learning and statistical machine learning methods, were not even in the distant future. The aim was to create an artificial brain for a machine, where the "brain" is the so-called "expert system", a software program that can integrate a large knowledge base and use it to solve problems in the same manner that a human expert could. The intellectual merits and achievements of a few AI systems designed solely to narrowly excel in a specific problem became the actual problem of the nascent field.
