Introduction

In modern poultry farming, the need for alternatives to probiotics is increasing due to concerns about the stability, viability, and potential side effects of using live microbes. Postbiotics have emerged as promising substitutes, offering similar health benefits without the risks. Postbiotics are non-viable microbial metabolitewhich exhibit benefits like promoting gut health, boosting immunity, and preventinfections, which are crucial for sustainable poultry production. Postbiotics enhance gut health by modulating immune responses, improve the microbialenvironment,and inhibit pathogenic growth. Furthermore, their incorporation can reduce theneed for antibiotics in poultry farming, contributingto a decrease in antimicrobial resistance. With the growing global population and increasing demand for animal protein, postbiotics offer sustainable solutions. The review concludes that postbiotics could revolutionize poultry farming, aligning with global efforts toward food security and the achievement of the United Nations Sustainable Development Goals, particularly Goal 2 i.e. Zero Hunger. Future research should focus on optimizing these additives for large-scale commercial use.This paper highlights the concepts of postbiotics, their mechanisms of action, current research advances, beneficial effects in poultry farming, and future prospects.

The stone fruit crops namely peach, Prunus persica, plum, Prunus domestica, apricot, Prunus armeniaca, almond, Prunus dulcis and walnut, Juglans regia are grown in wide range of climatic conditions ranging from subtropical to temperate regions. Peach and plum are also cultivated in mid and low hills in addition to temperate regions. Peach is the major stone fruit crop followed by plum, apricot and cherry. Walnut and almond on the other hand are major nut crops. A number of insect pests (~80) infest stone and nut fruits in various stages of the tree growth and development and cause direct and indirect loss out. Only few pests are of economic concern, the details of which are given hereunder

Peach leaf curling aphid, Brachycaudus helichrysi (Kalt.), Aphididae: Hemiptera

It is a polyphagous pest reported infesting 175 plant species of 115 genera of 49 families. It is a regular and key pest of stone fruits viz. peach, nectarine, plum, apricot and almond and

A cellular phone is also known as a mobile phone, cell phone, portable phone and a hand phone. It is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network.

The cell phone was invented by Dr. Martin Cooper who led a team of developers at Motorola and made the first cell phone call in April 3, 1973 at Motorola.

Today, cell phones are becoming capable of doing almost anything a computer is capable to do. Below, are few examples of what a phone can do?

Introduction

Any kind of garden established on the roof top of building is known as roof garden, which provides the opportunity to cultivate the quality vegetables, fruits and flowers in home. In this system plants and grasses are grown on a nutrition medium placed above a waterproof membrane. Roof gardening is mostly adopted in urban areas. It uses for decorative benefit, roof plantings make available food, manage temperature, hydrological remuneration, architectural improvement, habitats  for wildlife, frivolous opportunities, and in large scale it may even have ecological benefits (Louise, 2009). This considerably increases human health as adding organic cultivation.

Biosecurity means protection against infectious biological agents. These agents include bacteria, viruses, protozoa, fungi, parasites, and any other agents capable of introducing infectious diseases into a poultry flock. Biosecurity therefore means maintaining a flock, poultry house or premises in such a way that infectious agents do not have a chance to enter to cause diseases. The biosecurity may be categorized into three: Conceptual biosecurity, Structural biosecurity and operational Biosecurity.

Importance of Biosecurity

In modern poultry production, birds are reared under intensive system where large numbers are concentrated in small area. As a result, when an infectious agent enters a poultry house, there is probability for widespread dissemination if it is not contained. Besides, the broiler and egg industry of today is under increasing consumer and regulatory pressures to guarantee food safety and meet export requirements. As a result, broiler and layer operations around the world require the supply of breeding stock free of salmonellas specific to avian species (such as S. pullorum and S. gallinarum) and those that could cause outbreaks of human food-borne illness. Inadequate biosecurity can contribute to wide epidemics of highly pathogenic or exotic diseases. An infection by a virulent organism within a facility can be devastating, reducing without overt signs of disease. Once contaminated with pathogens, poultry facilities are extremely difficult and expensive to clean, sanitize and disinfect. Prevention of disease is always less expensive than treatment. The cost of implementing biosecurity system is smaller when compared to financial profit that can be made from production. Good biosecurity is therefore vital requirement in the best possible control of disease.

Urban forestry is not a new concept, but it is one which appears to have growing potential. With increasing urbanization in the 20th century, the incorporation of trees into urban settlements has also increased. The management of all trees within the urban area is considered a distinct discipline of forestry. Urban forestry was conceptualized in the late 1960s in North America, and grew out of what was initially termed environmental forestry. Trees and urban forests can make our cities cleaner, cooler, greener, safer, healthier, happier and nice places to live.

Introduction

Nitrogen constitutes 78% of the atmospheric gases and there is about 75,000 Mg N on each hectare of land. However, 99% of the atmospheric N is as N₂ and is inert and non-reactive, while the rest 1% or even less is the reactive-N. Reactive-N is linked with H, O and C and is responsible for the creation and sustenance of all life on the planet Earth. Nitrogen is the key nutrient that separates proteins from carbohydrates and fats, the three major macronutrients for humans. As a component of proteins, N is present in DNA and RNA, which carry the hereditary characters and then as the major constitute of the body muscles of humans (and animals). Plant growth and crop production are also very much dependent on the adequate availability of N in soil.

Pollinators provide an essential ecosystem service, namely pollination, and it is an intricate relationship between plants and animals where reduction or loss of either will affect the survival of both. It has been established that pollinating agents are essential for survival and reproduction of several wild plant species (Kearns et al., 1998). About 80% of the world’s flowering plant species are dedicated to animal pollination, mostly by insects (FA0, 2007). Although more than 750,000 insect pollinators have been described (Grimaldi and Engel, 2005), possibly as many as 30 million more await discovery and formal description (Erwin, 2004). In 2005, globally, pollinators’ pollination services economic value was estimated to be about €153 billion (Gallai et al., 2009). The United Nations also reported that the economics of ecosystems and biodiversity by insect pollination was valued at £134 billion. The depletion of insect pollinators is due to pollinators’ habitat destruction, heavy tillage, monoculture, injudicious use of pesticides and climate change and therefore, there is the need to create awareness on conservation and pollination management. Climate change is highly affected to species interaction as well as ecosystem ecology (van-der-Putten et al., 2004; Sutherst et al., 2007). Plant-pollinator interaction in both wild and cultivated plant species is under threat (Biesmeijer et al., 2006).

Introduction

Krishi Vigyan Kendras (KVKs) have marked their presence across India by executing various scientific as well as institutional reforms for the agrarian mass of our country. Right from its beginning in 1970s, farmers were actively trained for adopting different innovative tools and methods and were also provided with proper assistance in implementing them. The farmers were adapted to technical know-how of an introduced technology and produced significant results in the real f ield conditions.

KVKs provided proper training programmes on need-based curriculum in order to cater to the local and regional needs. This has also led to need assessment of various training needs and efficacies to make improvement in policies and future interventions. KVK can be instrumental in nurturing the process of gender empowerment by inviting and involving the farm women in the process of technological adaptation, adoption and socialization. There are methodological innovations as to how we can involve the farm women by employing and applying gender-sensitive KVK technologies as suitable for their job environment and climate. Especially in areas of value addition, rural crafts, women crafts, f ishery, horticulture and micro-finance, their roles are becoming more prominent and decisive. This is positive achievement in making them free from gender discrimination and impoverishment.

The knowledge score gained by respondents after training was more satisfactory in all aspects (58.33% had medium and 48.67% had high level of knowledge). The socio-economic factors of the participants viz. Education level played a significant positive role on the knowledge gain of the participants. (Upamanya et.al., 2020) Most of the farmers, i.e., 66.67 per cent with theoretical knowledge suggested that more field visits can be arranged, 63.33 per cent of the respondents suggested the training should be conducted in their own villages because the farm women cannot able to come to KVK by leaving their children and their regular household work and around sixty per cent (60.83 per cent) of the respondents suggested that organizing continuous and frequent training programmes for effective participation and retention of knowledge.

Dolichos bean or Hyacinth bean, Lablab purpureus (L).Sweet. (Syn. Dolichos lablab Roxb.) under the family Fabaceae (Leguminosae) and having Chromosome No.: 2n = 2x = 22 is one of the most ancient among the cultivated plants. Young, immature pods are cooked and eaten like green beans. It is grown throughout the tropical regions of Asia, Africa and America. In India, it is grown extensively in the cool season in Tamil Nadu, Andhra Pradesh, Karnataka, Madhya Pradesh, West Bengal and Maharashtra. The pods are one of the rich sources of protein and it also provides fair amount of carbohydrates, calcium, phosphorus sodium, magnesium and iron, b-carotene, riboflavin, thiamine and nicotinic acid.
Origin, domestication and adaptation in India
Dolichos bean or Hyacinth bean has been originated in India as wild forms of this bean are found in this country. From India, it was introduced to China, Western Asia, Egypt and other tropical countries of South and South-east Asia and Africa. Vegetable and pulse type dolichos bean belong to two distinct botanical varieties under Lablab purpureus viz., Lablab purpureus var. typicus and Lablab purpureus var. lignosus, respectively. Various forms and cultivars of both the cultivated types are available in India.

Modifying microclimates in agriculture involves altering the local climate conditions surrounding crops or plants to create a more favorable environment for growth. This can be achieved through various techniques when the crops are subjected to weather related stresses.
14.1. To Mitigate Moisture Stress during Droughts
When the crops are under moisture stress, the principles involved are conservation of soil moisture and reduce the evapotranspiration from crops. The moisture conservation can be achieved by suppressing soil evaporation using mulches (Fig. 14.1). The evapotranspiration can be reduced using antitranspirants. Some antitranspirents close the stomata of the leaves to reduce evapotranspiration. Some anti-transpirants increase the reflectance of radiation from the crops, thereby reducing heat load on crops. When crops are grown under irrigation in isolated patches, micro shelter belts can be provided across the predominant wind direction to reduce the increased evapotranspiration from advection. Advection is phenomena of horizontal transport of heat due to strong hot and dry winds.

Introduction
Antimicrobial resistance (AMR) constitutes a profound global health crisis, jeopardizing the efficacy of antibiotics and posing a severe threat to the foundation of modern medical practice. The rise of multidrug-resistant (MDR) pathogens, which exhibit resistance to multiple classes of antibiotics, has significantly escalated the global burden of infectious diseases, complicating treatment protocols and increasing morbidity and mortality rates. According to the World Health Organization (WHO), AMR could lead to 10 million deaths annually by 2050 if current trends continue, accompanied by economic losses projected to reach trillions of dollars due to prolonged hospitalizations, increased healthcare costs, and reduced productivity. The traditional antibiotic development pipeline has stagnated, hampered by scientific complexities, high financial costs, and stringent regulatory frameworks, resulting in a critical shortage of novel antimicrobial agents. This necessitates the exploration of innovative strategies to combat AMR and preserve the utility of existing antibiotics. Among these strategies, Crispr-Cas (Clustered Regularly Interspaced Short Palindromic Repeats and Crispr-associated proteins) systems have emerged as a groundbreaking gene-editing platform with transformative potential for addressing AMR. Initially identified as a bacterial adaptive immune mechanism, Crispr-Cas has been repurposed to enable precise targeting of genetic elements, offering novel therapeutic, diagnostic, and environmental solutions. This chapter provides a comprehensive analysis of Crispr-Cas systems in the context of AMR, exploring their molecular mechanisms, diverse applications, current limitations, and future prospects across clinical, agricultural, and environmental domains. By leveraging the precision and programmability of Crispr-Cas, researchers aim to develop targeted interventions that mitigate the spread of resistance while minimizing collateral damage to beneficial microbial communities.

INTRODUCTION

In the history of human development, woman has been as important as man. In fact, the status, employment and work performed by women in society is the indicator of a nation’s overall progress. Without the participation of women in national activities, the social, economical or political progress of a country will stagnate. Empowerment is a multi-dimensional process, which should enable women to realize their full identity and power in all spheres of life. It consists of greater access to knowledge and resources, greater autonomy in decision making to enable them to have greater ability to plan their lives, or to have greater control over the circumstances that influence their lives and free from shocks imposed on them by customs, beliefs and practices. Generally development with justice is expected to generate the forces that lead to empowerment of various sections of women and to raise their status.

Aonla or Indian Gooseberry (Emhlica officinalis Gaertn. syn. Phyllanthus embfica L.). belonging to family Euphorbiaceae. is an indigenous fruittree to Indian sub continent. It is one of the most important commercial crops suitable for marginal soils and various kinds of waste lands particularly salt affected lands. A lot of genetic variability is available in India with respect to growth and fruit quality characteristics of aonla. Almost all the budded varieties of aonla were selected from naturally occurring superior chance seedlings having in view their earliness, lateness, hardiness to adverse conditions, yield and superior fruit quality.

1-or successful aonla orchards, it is utmost necessary to have basic knowledge of various cultivars suitable for a particular set of environmental and soil conditions.

Growth, Fruiting Habits and Methods for Inducing Fruitfulness in Fruit Crops

•    Every plant has two distinct phases of development namely vegetative and reproductive.

•    In the vegetative phase, the plant only vegetative growth i.e. leaves, shoots etc.,

•    In the reproductive phases the plant produces reproductive growth i.e. flowers and fruits.

•    In case of annuals, these phases occur for a short period, each phase occurring only once and that too within the same season.

•    In perennials, the vegetative phase lasts for several years depending upon the variety and species. This is known as the pre-bearing period.

•    Once the perennial tree completes its pre-bearing period, the cycle of vegetative and reproductive phases might occur in each season or the reproductive phase may occur simultaneously along with vegetative phase without much distinction between the two.

Fertilizer N has been the key input in increasing cereal production throughout the world. In India, it made possible to achieve the yield potential of high-yielding dwarf varieties of wheat that led to ‘Green Revolution in 1968’. Nitrogen fertilization also increases protein content in wheat grains (Rajeswara Rao and Prasad, 1987) and leads to increased production of proteins in cereals (Prasad and Shivay, 2015). Cereal production in India increased from 42.4 million tonnes (Mt) in 1950–51 to 259.6 Mt in 2017–18, while fertilizer N application increased from 0.05 Mt to 16.96 Mt. However, the average agronomic ef?ciency of N (AEn) in India for cereals is only 9.5 kg grain kg–1 N (Sharma and Batra, 2011) as compared to global average of 24 kg grain kg–1 N for maize, 22 kg grain kg–1 N for rice and 18 kg grain kg–1 N for wheat (Ladha et al., 2005). Besides this, more disturbing is the fact that in irrigated areas the AEn declined from 13.4 to 3.4 kg grain kg–1 N during 1970–2005 (Biswas and Sharma, 2006). This is due to poor N management. Bulk of fertilizer N is applied broadcast on surface in most crops.

The genus Bougainvillea, although having broad range of adaptability along with diverging habitate is not rich in scientific literature. The available literature on description of elemental species and mode of origin and description of different sports (cultivated species) are very poor and all the literarture are not available at one place. On the basis of available literature (Philbert 1789, Humboldt and Bonpland 1808, Fitch 1854, Bailey 1914, Merril 1923, Standley  1931, Heimerl 1934, Hottes 1947, Bor and Raizada 1948, Preston 1950, MacSelf 1951, Sargeant 1951, Van 1951, Crane and Lawrence 1952, Holttum 1955a-d, 1957a,b, Pancho and Bardenas 1959, Marigowada 1961, Sharma 1962, Menninger 1970, Ramcharan et al., 1974, Zadoo et al., 1976, Linnaeus 1789, Swarup and Singh 1995, Willdenow 1798, McDaniells 1981, Rodale et al., 1997, Gordon 2002, Lopez and Galetto, 2002, Fatima et al., 2007, Kent et al., 2007, Kobayashi et al., 2007a,b, Hammad 2009, Lack, 2004, 2012) an attempts has been made to give a short description of elemental species and important role played by Bougainvillea cv.
