3.1 Training

Virtual orchards are sophisticated, simulated environments used to train agricultural robots in a controlled, risk-free setting. These virtual landscapes replicate real-world orchards with high fidelity, incorporating detailed models of trees, fruits, branches, and various terrain features. By leveraging advanced technologies like 3D modelling, physics-based simulation, and machine learning, virtual orchards provide a comprehensive platform for developing and testing robotic algorithms without the logistical challenges and costs associated with field trials. In these simulations, agricultural robots can perform various tasks, such as navigating through rows of trees, detecting and localising fruits, and executing precise pruning actions (Shamshiri et al., 2018). The virtual environment allows for testing different path planning and control algorithms, enabling researchers to fine-tune these systems for optimal performance.

Additionally, virtual orchards can simulate various environmental conditions, such as changing light levels, weather patterns, and the presence of obstacles, providing a robust testing ground for robots to adapt to dynamic scenarios. One significant advantage of virtual orchards is the ability to generate large amounts of training data for machine-learning models. Robots can be exposed to many pruning scenarios, enhancing their ability to generalize and perform effectively in real-world conditions. Furthermore, the use of virtual reality (VR) and augmented reality (AR) can aid in training human operators to control and supervise these robots, improving their proficiency and reducing the learning curve (Sarker, 2021).

The term robot is czech word, first time used by play write Karel Capek, in year 1920, applicable to the forced labour or serfs or slaves. The first commercial, digital and programmable robot, named ‘Unimate’ was built by George Devol in 1954.

This chapter describes the components to design the mobile platform. The UN estimates the world population will rise from 7.3 billion today to 9.7 billion in 2050. The world will need a lot more food, and farmers will face serious pressure to keep up with demand. Agricultural robots can be used to increase the production yields for farmers in various ways.

3.1 Role of Robots in Agriculture

A challenging problem in Mechanical Engineering and robotics is the design of a mobile robot. The robot must successfully traverse through its environment, including rough terrain, grass, hills, etc. For correct positioning of the robot, the wheels of the robot must have good traction and never lose contact with the ground. For improved manoeuvrability the robot must also be able to rotate around a centre point as close to its centre of mass as possible. All of these factors have been considered in the design of a second generation outdoor de- mining robot.

A rectangular frame for the robot allows the easier positioning and accessibility of parts within the robot, which is useful in the development phase. Having the wheels up front helps the robot drive onto a slope. A circular frame for the robot would allow the robot to rotate around its true centre, such a frame, with the wheel axle running along the diameter of the frame would need support at the front and back of the robot.

Rock gardens and pool are two most attractive features of the garden. These together can transform any part of the garden into a pleasing spot. Both are quite different from other common features and increase beauty of the gardens in manifold.

Rock Garden

The term rock garden refers beautification of a portion of the garden in combination with rocks and plants. Rock garden provides height and a rugged grandeur. A flat area can be converted into an elevated and graded one in combination with rocks and plants. This breaks monotony of the plain land and creates a feature of interest. The plants grow in the rock garden are different from others and add variety to the existing groups.

I. Rock Phosphate

Rock phosphate is natural source of phosphorus. It occurs as natural deposits of rock in Morocco, U.S.A., Egypt, Poland, Russia, Tunisia, Algeria, Brazil, Nauru and some Islands in the Pacific and the Indian ocean. It contains 20 to 35 percent phosphoric acid (P2 O5 ) but this phosphorus is in insoluble form. In India, some of rock phosphates occur in Udaipur and Jaisalmer districts (Rajasthan), Purulia (West Bengal), Singhbhum (Zharkhand) and Mussorie (Uttrakhand). Most of these phosphates are classified as low grade phosphate since its phosphoric acid content is less than 20-25%. The total reserve of low grade rock phosphate is estimated to be around 165 million tonnes of which nearly 70 million are reported to occur in Rajasthan. The other economically viable deposits are in Mussorie (Uttarakhand), Jhabua district (Madhya Pradesh), Singhbhum (Zharkhand) Kasipatnam (Andhra Pradesh) and Purulia district (West Bengal). Rock phosphate is the basic raw material for manufacture of superphosphate and other kind of phosphatic fertilizers. It is reported above that India has mostly low grade rock phosphate. Hence India has to spent huge amounts of foreign exchange to import high grade rock phosphate containing around 32-35%, P2 O5 for manufacture of phosphatic fertilizers.

Soilless media or culture

Gravel culture is a general term which applies to the growing of plants without soil in an inert medium into which nutrient solutions are usually pumped automatically at regular intervals. Haydite (shale and clay fused at high temperatures), soft- or hard-coal cinders, limestone chips, calcareous gravel, silica gravel, crushed granite and other inert and slowly decomposing materials are included in the term “gravel”. The more important greenhouse flowering crops include roses, carnations, chrysanthemums, gardenias, snapdragons, lilies, asters, pansies, annual chrysanthemums, dahlias, bachelor buttons and others.

Media ingredients and Mix

Commercially available materials like peat, sphagnum moss, vermiculite, perlite and locally available materials like sand, red soil, common manure/ compost and rice husk can be used in different proportions to grow greenhouse crops. These ingredients should be of high quality to prepare a good mix. They should be free from undesirable toxic elements like nickel, chromium, cadmium, lead etc. Most common medium other than soil used in India in greenhouses is coco peat. In other countries these are Rockwool and Peat-vermiculite.

A rock is the home for minerals. In other words, naturally occurring coherent aggregate of minerals (or glassy mass) will constitute a rock. Like in a family, more often, there are several members(minerals) within a rock but occasionally just one mineral also makes a rock( olivine in dunite, quartz in quartzite and calcite in marble). The root word petros is of Greek origin, meaning rock and a petrologist is one who specializes in the study of rocks. The three main categories of rocks are distinguished on the basis of their origin. Igneous rocks are the ones that have solidified from a molten state in deep seated conditions, as also on the surface while Sedimentary rocks are formed from the erosion of preexisting rocks and subsequent re-deposition or precipitation of the resulting material at or near the surface. Metamorphic rocks on the other hand, are formed by the action of heat or pressure or both on preexisting rocks.

The theme of rocks is split into five chapters. The first chapter introduces the theme of petrology, petrography and petrogenesis., presents rocks as the storehouses of minerals and their grouping into three classes. The second chapter presents all the important aspects of igneous rocks( plutonic, hypabasal and volcanic) including their forms, texture, structure, chemistry and classification and variation diagrams. It also presents a somewhat sufficient description of different kinds of igneous rocks under the categories of ultrabasic, basic, intermediate acid and alkalic rocks. The chapter ends with an introduction to some of the peculiar kinds of igneous rocks and also presents a brief account of causes of diversity among igneous rocks.

Chapter III is devoted to the study of sedimentary rocks beginning with nature and categories of sediments and general factors that affect sedimentary process. Sequence of breakdown, sedimentary minerals, depositional environment , classification of sediments and sedimentary rocks is the next theme followed by primary and secondary and biogenic structures. The next theme is a description of important sedimentary rocks under different categories ( rudaceous, arenaceous, asrgillaceous and rocks of biogenic origin). The chapter ends with introducing sedimentary rocks as the home for natural resources.

Chapter IV dwells on metamorphic rocks distinguishing between metamorphism and metasomatism. Metamorphic minerals and naming metamorphic rocks is the next theme. Next, agents and types of metamorphism is followed by grade, zones, index minerals and metamorphic facies. Textures, structures and the description of metamorphic rocks comes next. The use of triangular plots in metamorphic petrology is introduced and ends with considering metamorphic process in the light of global tectonics.

The last chapter is a short but important chapter- The Rock Cycle which combines the three important geo-processes of igneous activity, sedimentary process and metamorphism while presenting a birds eye view of them. It considers the movement, not only of matter but also the energy that drives the rock cycle. The chapter closes with introducing the rock-cycle-mineral deposits relationship.

Rodents are well recognized pests and are considered the number one enemy of man. These animals, though considered primitive, have been so successful and abundant worldwide that they alone account for more than half of the known mammalian fauna. They can subsist on a variety of food and even without water for a long time. Due to their prowess of adaptability, they have successfully adapted to varied ecological and physiological niches, and therefore are inhabitants of practically each and every latitude and altitude. They multiply at super fast speed because they become sexually mature when they are just 6-8 months old. They then pose a challenge to man in all respects. According to Prakash (1988) in India there are 135 species and about 300 sub-species of rodents belonging to 46 genera. At least 15 of these rodent species are known to be the serious pest of public health hazard (Jain and Tripathi, 1988). Rodents not only damage the crops in the fields, where the infestation occurs at all stages of food production, processing, storage and distribution, they are also responsible for a number of diseases in the human beings.

Rodents attack the-crops shortly after sowing, during the vegetative growth and during the ripening of the seed heads. They damage the various crops of the kharif season viz., jowar, maize, ground nut and cotton as well as the crops of the rabi season viz., wheat and barley etc. They damage other crops also which include paddy, sugarcane, soyabean and Bengal gram etc. Hence some well planned rodent management is the need of the time and before going for the planning of any control method in a given situation it is essential to have an estimation of the population and the species involved.

Economic Importance of Rodent Pests

• They consume and damage foods in the fields and in stores. In addition, they spoil it in store by urine and droppings reducing the sale values.
• Due to their gnawing and burrowing habit they destroy many articles (packing, clothes and furniture) and structures (floors, buildings, bridges, etc). By gnawing the electrical cables they can cause fires.
• They are responsible for transmitting diseases dangerous to human and domestic animals.

Among many pests of agricultural crops and stored grain products, rodents are the major pests which do the great damage. Rodents including rats, mice and squirrels are gnawing animals having chisel like teeth. They have highly developed sense of smell, taste and hearing. They are omnivorous and feed on grains, vegetables, fruits, meat and other products in the houses or in the fields. Rats daily consume food equal to about 10 per cent of their body weight and the figure may go up to 30 per cent in case of mice. Rats are among the most destructive pests of paddy in the field causing about 5-10 percent damage. It is estimated that these animals destroy 30 per cent of the total world’s cereal production. In India, 10 million tonnes of food grains are lost every year. It is often said that if rodent ravages could be controlled, a huge amount of food grains can be saved.

Of the 84 species of order Rodentia in India, 50 belong to family Muridae. The important ones belong to two sub-families, viz., Murinae and Gerbillinae. Murinae has 18 species of genus Rattus, 2 of Bandicota, 7 of Mus, 2 of Apodemus and a few each under eight other genera. The sub-family Gerbillinae has 2 species of Gerbillus, one each of Tatera and Meriones. Family Sciuridae has 10 species of flying squirrels and 13 species of tree squirrels in India.

ABSTRACT

Family farming is the blending of experience, skill, managerial qualities, business strategies and finally economic independence because this type of farming involves the blending of different minds of the family members. There is not any doubt in saying that youth are the of future. This is the time between childhood and adulthood. It is the time when a young individual get out of their dreamy world of childhood and face some of the most complicated realities of the world. Family farming is still facing the problem of urbanization and unemployment. But youth of present scenario are the solution of every problem because skilled youth of rural background can drive future economic growth as they are innovative in bringing and applying new ideas on a large scale. Rural youth are enthusiastic and they can act as good leaders as their orientation is scientific. Youth support family farming as well as perform gender specific activities. They are said to be the key to sustainable and innovative development. Investment in rural youth is the key to country‘s progress and boost economic opportunities. Rural youth of today want that their capabilities should be utilized for producing food and for conserving productive resources in rural environment. Their mental skills make them different from others so Govt. should adopt such policies that mark the correct value of their skill. This research paper emphasizes the role of rural youth in agriculture and family farming and what are their aspirations from this sector.

ABSTRACT

Agriculture is an important sector of Indian economy that contributes about 17% to the total GDP and provides employment to over 60% of the population. But, the villages are becoming poorer and poorer and only older generations are left there to do the agricultural operations. During the past two years, cost of food items like grains, pulses, oil and vegetables are increasing, month after month. Family farming is the best approach to produce agricultural products economically, utilizing locally available resources and crop residues and manpower very efficiently and sustainably. Family farming is a way of life” - there are unique advantages - the security of access and control over resources, meeting multiple needs of the family – food and income, the relationships with nature, the bonding with the past, present and future; ensuring freedom from external exploitation as well as freedom to do your own way. Family farms as multipurpose enterprises have been serving as buffers in times of disasters, as glue of social bonding, often functioning as a ’value web’ between farming families and communities. The United Nations defines youth as young men and women from age 15 to 24. The present situation of rural youth in developing countries can generally be characterized by illiteracy, lack of educational and training opportunities, unemployment, under-employment and the flight of large numbers of rural youth to the cities. There are serious challenges too – stifling and non supportive policy environment, lack of extension system to handle the farmer’s distinct needs and capacities, and lastly ‘converting’ family farms to be ‘business like’ models. However, successful pilots can become big impact programmes, for instance, as in Andhra Pradesh, through NGO-GO collaboration. Hence, rural youth need to be prepared in: (a) improving their capabilities to produce food and to conserve productive resources in the rural environment, (b) improving skills and abilities in undertaking income-generating activities in rural areas, (c) relieving population pressure and improving nutrition and the well-being of farming families and (d) developing leadership and the ability to work well with others in group and community situations.

A number of animals are used in this country for conducting a variety of experiments. There has been a long felt need to prescribe guidelines and procedures for animal experimentation covering all aspects. The Central Government has constituted a Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCSEA) under PCA Act 1960 to ensure that experimental animals are not subjected to unnecessary pain or suffering before, during or after the performance of experiment on them. For this purpose the government has made “Breeding of and Experiment on Animals (Control and Supervision) Rules, 1998 as amended during 2001 and 2006 to regulate the experimentation on animal. Under these provisions, the concerned establishments are required to get themselves registered with CPCSEA, form IAEC, get their Animal House Facilities inspected, and also get specific projects for research cleared by CPCSEA before commencing the research on animals. Further, breeding and trade of animals for such experimentation are also regulated under these Rules.

Calcium, anti-oxidants and certain enzymes are reported to play vital role in extending the shelf-life of harvested produce of many horticultural crops especially fruits. They help in maintenance of cell wall structure. Being an important constituent of cell wall, in the form of calcium pectate, it helps in maintenance of cell wall structure. Antioxidants are highly beneficial in extending the shelf-life of fruits besides maintaining the quality. Similarly, some enzymes play a key role in preserving the fruit quality and prolonging its market life. As some fruits are catergorized under ‘Low volume high value fruits’, it is essential to extend their shel-flife for reducing the post-harvest losses of fruits and also to reap better remuneration. Thus, it becomes indispensable to review the role of Ca, anti-oxidants and enzymes which are beneficial in keeping the harvested produce afresh for a relatively longer period.

Abstract

Research has demonstrated that nutrition plays a crucial role in the prevention of chronic diseases as most of them can be related to diet. Functional food enters the concept of considering food not only necessary for living but also as a source of mental and physical well-being contributing to the prevention and reduction of risk factors for several diseases or enhancing certain physiological functions. One of the most clear objectives of the study of functional foods is to identify and validate biological markers in order to understand the interaction mechanisms between the food component and a body function. Epidemiologic and laboratory data from previous studies suggests that diets rich in fruits and vegetables are associated with a reduced risk of various types of cancers. The reduction in cancer risk may be attributed to the abundance of a family of specific compounds referred to as anthocyanins, which are found in various berries. Anthocyanins are water soluble pigments responsible for the blue, purple, and red color in many plant tissues Strawberry is one of “super fruits”, since they can form a significant component of the diet and are a potential resource of functional foods and nutraceuticals due to their antioxidant capacity and nutritional quality. Strawberries contain high levels of anthocyanins and they are also well liked by consumers. Popularity of strawberries in the consumer market makes them an ideal focus for chemoprevention studies. Strawberries are a rich source of phytochemicals (anthocyanins, catechins, the flavonols quercetin and kaempferol, and ellagic acid) and an important source of essential nutrients (ascorbic acid, potassium, folic acid, carotenoids, B-vitamins). Strawberries are consistently ranked among the top food sources of polyphenols and antioxidant capacity; the preventive and therapeutic health benefits of strawberries may be attributed to the synergistic effects of these bioactives and the nutrients contained in the fruit. These bioactive photochemical contribute the major health-promoting function. Strawberries have shown a remarkably high scavenging activity toward chemically generated radicals, thus making them effective in inhibiting oxidation of human low-density lipoproteins. Antioxidant activity of strawberries could contribute to the prevention of cancer, cardiovascular and other chronic diseases. Hence strawberry can be used as a vital and indispensible functional ingredient for the development offunctional foods and nutraceuticals.

Role of water
Water is the principal constituent of living plants as well as animal body. With the maturity of seed, water content decreases. Animal body is composed of two thirds of water – intra and extra cellular fluids, and that a feed is any substance used by the body for building tissue, it is obvious that water is very important nutrient. Experiments have shown that animals may live for 100 days without organic feed, but they may die within 5 to 10 days, when deprived off water. Cell rigidity and elasticity imparts a definite form to body, which may be changed by the liquid content of the cell. Due to its high dielectric constant, oppositely charged ions co – exist in water without much interference. Hydrolysis is an important chemical process in digestion and other metabolism, where H+ and OH- ions of water are introduced into bigger molecules and these bigger molecules are broken down into smaller units.
Lubrication is yet another important function where water prevents friction or drying in joints, conjunctiva, mouth, pleura surrounding lungs, other soft organs. Body heat regulation is carried out due to certain properties – for example, due to high specific heat conducting power, water can carry away heat from the site of production and distributing it throughout the body. Yet another due to such property, highest latent heat of evaporation from skin, lungs or tongue. Oxygen and carbon di oxide are soluble in water, hence gaseous exchange takes place in the tissues, for example, fish. The “aqueous humour” of eye helps to keep up the ‘shape’ and ‘elasticity’ of the eye – ball and acts as refractive medium.

Abstract

People are the most important and valuable resources of any organization. Dynamic people can build dynamic and growth-oriented organizations. No wonder that late Homi J Bhava advocated on identification and selection of a dynamic scientist and building a laboratory ‘for’ him and ‘around’ him and not the reverse, that is, building a laboratory with certain aim and then search a suitable candidate to steer it. Effective employees can contribute to the effectiveness of the organization. Competent and motivated people can make things happen and enable an organization to achieve its goal. Therefore, organizations should continuously ensure that the dynamism, effectiveness, competency, and motivation of its people remain at a high level. Human resource development is a continuous process to ensure the development of employee dynamism, effectiveness, competencies and motivation in a systematic and planned manner.

Micronutrients play an active role in the plant metabolic processes from cell wall development to respiration, photosynthesis, chlorophyll formation, enzyme activity, hormone synthesis, nitrogen fixation, etc. Micronutrient requirements of crops are relatively small. Use of chemical fertilizers with accompanied changes in soil management practices resulted in steady decrease in micronutrient content in soil. The future of agriculture depends on sustainable management of land, water, flora, fauna and the atmosphere. In order to produce 240 m tones of food grains by the end of twentieth century, removal of major nutrients from soil will be to the tune of 7 m tones N, 2.7 m tones P2O5 and 11.2 m tones K2O. Similarly, a good amount of secondary (Ca, Mg, S) and micronutrients would also be removed proportionately which should be compensated through application of well rotten FYM or micronutrient fertilizers in soil.

Introduction

Compared to the previous decades, the scope and power of intellectual property rights (IPRs) in agriculture and biotechnology has grown substantially and their international reach has expanded. The IP regime has set up the stage for healthy competition among research centres and industries for developing and seeking novel technologies. However, compared to developed countries, once the technology is created, not much attention is paid in the developing nations on their commercial, policy, environmental, ethical and societal implications. Hence, better techniques are needed for their management, to create policy and educate professionals to commercialize and govern them. Due to the critical role of technology in a competitive environment, strategic technology management is important for farmers and agri-enterprises too. The translation of nascent technologies into new products/ services and their commercialization requires some amount of hand-holding, mentoring and incubation support.

ABSTRACT

Ethical conduct of research is utmost important which form the basis of overall development of society. Academic institutions can play key role in promoting scientific integrity by creating awareness about scientific misconduct and can frame policies to curb scientific misconduct. As a part of course curriculum knowledge about various issues related to academic integrity can be easily passed to young researchers and students of the institution. Awareness programs can play significant role in promoting research integrity for which academic libraries can be the frontrunner. Librarians’ role is also changing as they have not limited themselves to traditional services but are also providing web based services to the users. They can support research community by providing services like reference management through the use of reference management tools and data management and preservation services. Faculty development programs are also helping the working librarians to update their knowledge. This article discuss about the concept of academic integrity and role of academic institution in promoting it in general and library in particular. PA U library faculty has taken a lead in raising the awareness of students and researchers about research and publication ethics by teaching this course to as part of the course curriculum to research scholars and post graduate students of the university. It is also facilitating teaching community and researchers in plagiarism checking of the manuscripts through the use of antiplagiarism software.

Meaning of Advertising

According to Concise Oxford Dictionary, the word to advertise means to make generally or publicly with a view to increasing sales. The word ‘advertising’ is derived from the Latin word ‘advertese’ which means ‘to turn (the mind) to’. Advertising means providing adequate knowledge about some special product/service/idea to potential consumers so that they are stimulated to buy it. Adequate knowledge about a product means to let people know the name of the product, its function, size, price and place of its availability. The organizations providing service or idea give information regarding where, how and on what conditions their service or idea can be made available and how the same can be helpful to the people. Today is the age of competition. Consumers buy commodities after careful consideration. Under the circumstances, manufacturers are faced with the problem of how to motivate the consumers to buy their product. To find a solution to this problem, manufacturers make use of advertising.

Introduction

Agriculture and allied sectors contributing significantly to rural employment generation. It also contributes almost 18% of GVA (Gross Value Added) in Indian Economy at current prices (Economic Survey of India 2016-17). It remains sustaining livelihood security with nutritional security and help in social transformation of the country. Second half of 20th century witnessed the change of traditional and subsistence Indian agriculture into a commercial activity. Green revolution of sixties paved the way for entry of agribusiness companies selling seeds, fertilizers, pesticides and farm machineries. Agriculture today faces many challenges which include globalization and market liberalization, food price crises, natural resource depletion, climate change, rapid urbanization, changing production and consumption patterns, demographic changes etc. Market driven agriculture production is need of the hour since marketing has become a challenge for small farmers. Agri- preneurship development can be key in this scenario.

Introduction

More than three billion people are at risk of poverty due to land degradation caused by humans (Kansanga, Kerr, Lupafya, Dakishoni, & Luginaah, 2021). The implementation of Soil Sustainability Management (SSM) practices remains low among smallholder farmers, despite the fact that SSM has developed as a generally accepted technique to tackling soil degradation in Agro ecosystems (Kansanga et al., 2021). When it comes to food, water, energy, climate, biodiversity, and the provision of ecosystem services, soil plays a pivotal role in addressing these global environmental sustainability concerns (McBratney, Field, & Koch, 2014). The availability of food, fiber, clean water, and a varied landscape are all dependent on healthy soil.

INTRODUCTION

Mizoram is a hilly terrain lying in the north eastern part of the country. The total geographical area of the state is 21, 087 sq. km and lies between 92º 15/ to 93º 29/ E longitude and 21º 58/ to 24º 35/ N latitude. Out of six agro climatic zones of the NEH region, Mizoram comes under sub tropical hill zone and posses a sub tropical and humid climate due to high rainfall (Fig. 1). These climatic conditions are very conducive for the cultivation of a large number of agri-horticultural crops. The physiography of the state is divided into hills and valley lands. About 90 % area of the state comes under hills and only 10 % area is under valley. The valley lands are sporadically distributed in small patches except in Champhai district. The slope of the hills in Mizoram is much steep as compared to the other states in the North Eastern region. The land use statistics of the state is presented in Table1.

shrubs with crops and livestock in ways that create diverse, productive, and sustainable land-use systems. In natural farming, where minimal chemical inputs are used, agroforestry offers numerous environmental and economic benefits, making it a valuable approach for sustainable agriculture.
1. Soil Health and Fertility
Soil health and fertility are the cornerstones of any sustainable agricultural system, particularly in natural farming, where synthetic inputs are minimized or avoided altogether. Agroforestry, an agricultural practice that integrates trees and shrubs into farming systems, plays a key role in maintaining and enhancing soil health and fertility through natural processes. Here’s how agroforestry significantly improves soil conditions and sustains fertility over time. One of the primary ways agroforestry enhances soil fertility is through nutrient cycling. Trees and shrubs shed leaves, twigs, and other organic matter onto the soil surface, forming a layer of mulch. As this organic matter decomposes, it releases essential nutrients such as nitrogen, phosphorus, and potassium back into the soil, which are then available for uptake by crops. This process mimics the natural nutrient recycling seen in forests, reducing the need for chemical fertilizers and supporting the goal of low-input natural farming. Some tree species used in agroforestry are nitrogen-fixing, such as certain types of legumes like Gliricidia and Leucaena. These trees form symbiotic relationships with nitrogen-fixing bacteria in their root nodules, converting atmospheric nitrogen into forms that plants can use. As a result, these trees contribute nitrogen directly to the soil, boosting its fertility and helping to meet the nitrogen needs of companion crops without synthetic fertilizers. Agroforestry improves soil  structure by encouraging the formation of stable soil aggregates.

The unsustainable, faulty, environmentally detrimental modern agricultural practices and their plausible deleterious effects on one side and challenges like global climate change, ever shrinking land and water resources and loss of biodiversity on the other hand are the main problems that Agriculture is facing. Hence, there is a need to adopt a set of ecofriendly and climate smart practices to achieve sustainable development goals (SDGs). Agroforestry and organic farming (farming without chemicals) are the two important concepts projected to mitigate the effects of climate change, enhance soil health, encourage crop diversification, promoting biodiversity and achieving climate resilience. We made an attempt to synthesize the available information on the role of agroforestry in promotion of organic farming.

1. Introduction

Agroforestry is a land use system that integrates trees, crops and animals in a way that is scientifically sound, ecologically desirable, practically feasible and socially acceptable to the farmers (Nair, 1979). It is a collective name for land use systems and technologies, where woody perennials (trees, shrubs, palms, bamboos, etc.) are deliberately used on the same piece of land management units as agriculture crops and/or animals in some form of spatial arrangement or temporal sequence. It includes both ecological and economical interactions among the different components. Nearly 43% of world’s agricultural land has at least 10% tree cover, which suggests that agroforestry is widespread and infact, it is present in all continents. Agroforestry accounts for nearly 45.4 m-ha globally and 23.25 m-ha of land in India (Rizvi et al., 2019; Anonymous, 2020).

ABSTRACT

Tree component of agroforestry systems produce large biomass of varying nutrient concentration to serve as alternative to inorganic fertilizers under integrated nutrient management or organic farming. Additionally, agroforestry systems proved effective in conserving soil and rainfall and brought down soil loss up to 0.2 t ha^-1 and runoff up to 1.8 per cent of rainfall. Introduction of grasses in aonla conserved up to 31 cm of rainwater, 28 q ha^-1 of soil, 11 kg ha^-1 of N and 2 kg ha^-1 of K₂O. Conservation coupled with ameliorative capacity of agroforestry systems helped in building organic carbon and nutrients and improving soil physical, chemical and biological properties.

Management approaches to soil, including problems of soil degradation and low soil fertility, have recently undergone major changes. The earlier concept was to concentrate on achieving high levels of production from the more fertile areas, leaving the marginal lands for extensive use only. Steeply sloping and highly drought-prone areas were mostly left without any cultivation as production from these areas was hardly cost effective. Soil constraints were to be overcome by inputs like improved crop varieties, fertilizers, chemical control of pests and diseases, and the use of irrigation.

The approach of use of newly developed high yielding crop varieties, improved agronomic management practices, use of chemical fertilizers, efficient water management and timely plant protection measures has been successful in achieving large increases in crop productivity in recent years. On the other hand, continuous application of fertilizers at higher rates leads to environmental problems. Yield responses to fertilizers have declined because of soil physical degradation and micronutrient deficiencies. Above all, large numbers of poor farmers simply can neither afford high levels of fertilizers and other purchased inputs, nor do they have the capital to take on the risk involved in their use. Increasing the area under irrigation has also run into severe constraints in the form of limits to available freshwater resources.

In spite of the fact that the forests are the wealth of a nation and play a vital role in the economy of the country, not much attention has been paid to their promotion, protection and conservation. The forests of India have been reduced to 19.27 per cent (Gupta and Khajuria, 2000) and/or 23 per cent including 20.55 per cent forest cover and 2.48 tree cover (Sharma, 2005). It is much less than as prescribed in the National Forest Policy (1952), according to which onethird i.e. 33 per cent of the total land area of the country must be under forest.

4.1 Introduction

Pests and plant diseases pose serious risks to global agriculture (Strange and Scott, 2005; Oerke, 2006). Plant diseases and pests are the natural disasters that can impede a plant’s normal growth throughout the plant’s whole life cycle, from seed formation to seedling growth and may result in plant death (Liu and Wang, 2021). Diseases reduce yields in a number of important crops by 21–30% globally (Savary et al., 2019), whereas insect infestations reduce crop output by 30–33% annually (Kumar et al., 2019). For the management, accurate disease diagnosis and pest identification are essential. Artificial intelligence (AI) techniques can be a crucial addition to enable the monitoring of plant diseases and pests at a coarse scale, as traditional field scouting of these pests and diseases is labor-intensive, subject to bias, and typically shows low efficiency (Mahlein, 2016).

Agriculture is undergoing a revolution because of artificial intelligence (AI), which is replacing outdated techniques with more effective ones (Talaviya et al., 2020). AI intervention in agriculture is helping farmers increase productivity and reduce adverse environmental effects (Sujawat, 2021). The application of AI techniques has created new opportunities for scientific research as well as new instruments and ways for handling and analyzing vast volumes of data. An important benefit of AI is its capacity to spot patterns in data that are not immediately obvious or available to humans. This allows for previously unattainable new insights and discoveries (Angermueller et al., 2016; Eraslan et al., 2019). AI is currently changing how we work and live, yet its influence on pathology and entomology research is still underappreciated. AI’s cost-effectiveness, precision, quickness of performance, and adaptability are its core concepts in agriculture (Eli-Chukwu, 2019). In agriculture, artificial intelligence not only helps farmers use their abilities, but it also guides them to obtain better quality and larger yields with fewer resources (Khandelwal and Chavhan, 2019). AI-based technology addresses the issues that agricultural sector faces and helps to increase efficiency in all areas. These challenges include crop harvesting, irrigation, soil content sensitivity, crop monitoring, weeding, harvesting, and establishing.

Abstract

Natural plant products are known to prevent several deleterious diseases. This potency of plants to act as medicinal therapeutic source is due to the presence of various bioactive compounds including alkaloids, phenols, flavonoids and glucosinolates (GSLs). Among array of these compounds, GSLs are important class of plant secondary metabolites. The mechanical or physical injury to plant leads to the activation of this “GSL-myrosinase” system resulting in the formation bioactive compounds viz., thiocyanates, nitriles, isothiocyanates, and epithionitriles. Out of these compounds, isothiocyanates (ITCs) are well known for their therapeutic properties. Allyl isothiocyanate (AITC) commonly known as “mustard oil” is one of the naturally occurring ITC which is derived from hydrolysis of sinigrin, the major GSL in cruciferous vegetables like horseradish, wasabi, brussels radish etc. Due to high bioavailability in human body, it has been widely studied for its important bioactivities. Therefore, this review highlights the significant biomodulatory effects viz., antioxidant, antimutagenic, in vitro, in vivo anticancer, antimicrobial, and insecticidal activities of AITC.

Bone being a dynamic tissue undergoing constant biological changes, organic and mineral phases of fracture healing need an optimum general body metabolism and even a slight deviation from normal condition of the body is likely to cause considerable alterations in the healing process. Facture healing can be modified by variety of endogenous or exogenous factors that affect the metabolic function of cells. These factors include transforming growth factor beta, bone morphogenetic proteins, hormones, vitamins and prostaglandins. Anabolic steroids have the property of preventing the destruction and elimination of nitrogenous substances and minerals from the body. They help, thus, to have a positive nitrogen and mineral balance which is essential for healing and regeneration of any kind of tissue in a living organism. This chapter is undertaken to observe the effect of anabolic steroid (Durabolin) on fracture healing.

This study is conducted on ten clinically healthy adult New Zealand White rabbits of either sex divided into two equal groups (X and Z) consisting five animals each. All the animals are kept in standard diet and management throughout the experiment. In all animals, midshaft segmental defect (1cm) are created in both the ulnae under thiopental (2.5%) anaesthesia. In test group (Gr X), 10mg of Nandrolone phenyl propionate (durabolin) is injected intramuscularly in 5 days interval at 7 occasions. Lateral and anterio-posterior radiographs are taken on days 0, 7, 14, 21, 28 and 35 postoperative days. The radiographs are observed for progress of fracture healing and complications, if any, at different intervals.

Inflammation at the fracture site is increased upto 4^th postoperative days in all the animals of both groups, and then the limb is normal in appearance by day 7. Surgical wound healing is by first intention in all the animals. Earliest return of weight bearing is seen in animals of test group followed by control. Body weight and food intake are increased two-fold in the test group of animals.

Abstract

Anaerobes are a diverse groups of microorganisms which do not require oxygen or energy for respiration/metabolism and are one of the important components of nitrogen cycle. They are capable of using various other organic and even inorganic materials as electron acceptors during respiration. Anaerobic based wastewater treatment is a biological approach where microorganisms degrade organic contaminants (i.e. rich in carbon and nitrogen) in the absence of oxygen. In this chapter, the role of anaerobes in wastewater treatment has been discussed as it offers an alternative, cheap and eco friendly treatment technology among different biological treatment methods. Anaerobic biological treatment of wastewater is well developed, understood, and frequently used in anaerobic digesters to treat complex organic carbon and nitrogen compounds such as primary and secondary wastewater sludge. The anaerobic sludge contains diverse groups of anaerobic microorganisms that work together in association via a multistage processe consisting of the following biochemical reactions like hydrolysis, acidification, acetogenesis, and methanogenesis thereby converting the organic matter to biogas. The composition of biogas includes 70% methane (CH₄) and 30% carbon dioxide (CO₂) in addition to traces of other gases (e.g., H₂ and H₂S). The methane produced as a by-product can be used as an energy source. The potentiality of anaerobes in anaerobic based bioreactors for its maximum efficiency can be implemented in a variety of ways. The chapter discusses about the working principle, performance, treatment potential, and cost implication in the application of anaerobic treatment technology. The main bioprocess parameters such as pH, temperature, mixing, organic loading rate (OLR), and hydraulic retention time (HRT) have also been discussed in brief. Anaerobic treatment offers several benefits over aerobic treatment, including lower energy requirements, less chemicals, low capital, operation, and maintenance costs, and less sludge production. Hence, it saves money and the environment and overall simplifies the whole process.

Biofilms are resistant to antibiotics even at high concentrations (Costerton et al., 1999).This could happen when the diffusion of the antibiotic within the biofilm matrix is inefficient and results in slow growth rate of biofilm cells (Davey et al., 2000), there could be the presence of persistent cells and antibiotic-resistant small-colonies (Hogan and Kolter, 2002; Kolenbrander, 2000).Studies have proved that antibiotics can inhibit biofilm formation. An antibiotic azithromycin, is known to inhibit Pseudomonas aeruginosa biofilm. Biofilm colonies become resistant at higher concentrations of the antibiotics whereas at low concentrations these can be induced (Mah and OToole, 2001). P.aeruginosa is commonly present in the lungs of patients infested with cystic fibrosis. The clinical isolates show resistance to azithromycin (MIC>64 pg/ ml).However, low doses of azithromycin have shown improvement in lung function in patients with cystic fibrosis (Borriello et al., 2004). If antibiotics are given at low concentrations (below the MIC) than it induces biofilm formation in a variety of bacterial species. Sub-MIC concentrations of tobramycin can induce biofilm formation in P. aeruginosa. The use of antibiotics in agriculture, as growth promoters have shown to expose bacteria to low levels of the drugs and has caused havoc (Smith et al., 2002).

Introduction

Agriculture has been the cornerstone of human civilisation for millennia, providing sustenance and livelihoods to communities around the world. As the global population continues to grow, reaching an estimated 9.7 billion by 2050, the need to ensure food security becomes increasingly urgent. However, this burgeoning demand for food coincides with numerous challenges such as climate change, dwindling natural resources, and the pressures of sustainable farming practices. To address these complex issues and meet the world's food requirements sustainably, modern agriculture must embrace innovative technologies. One such game-changing technology that has emerged in recent years is Artificial Intelligence (AI), which is revolutionising various industries, including crop production. AI is the simulation of human intelligence processes by machines, particularly computer systems. It encompasses a range of capabilities, including learning, reasoning, problem-solving, perception, and language understanding. When applied to agriculture, AI holds immense promise to transform how we grow crops, optimise resource utilisation, and enhance overall productivity (Fan et al., 2012). By leveraging AI's power, farmers can make data-driven decisions, improve efficiency, and implement precision farming techniques tailored to specific field conditions. By employing AI technologies, it is possible to mitigate the impact on natural ecosystems and enhance worker safety. This, in turn, can contribute to keeping food prices down and ensuring that food production remains in step with the growing global population (Ranjan et al., 2023).

Introduction

Fast and efficient dissemination of suitable technological information from the Agricultural Research System to the Farmers in the field and reporting of farmers’ feedback to the research system is one of the critical inputs in Transfer of Technology. Today India is at the verge of technology revolution with immense number of agriculture, home science and livestock technologies developed by the research institutes to enhance the agriculture and livestock production. These technologies have changed the total production of agricultural commodities in the country.

Abstract

Of the various rhizosphere associated bacteria, Azospirillum species are probably the most studied and appear to have significant potential for commercial application. During the last 35 years of studies of Azospirillum–plant interaction, over 20 proposals were suggested for the mechanism of action by which Azospirillum  enhances plant growth, yield and nutrient uptake. Besides, fixing the nitrogen with associative symbiosis, they impart a number of beneficial effects on plants such as phytohormone production, siderophore production, enzyme production, proliferation of root system, enhanced water and mineral uptake, mobilization of minerals, mitigation of environmental stressors of plants, and moderate biocontrol potential. The following plant responses to Azospirillum inoculation in agriculture crops were often reported: increase the germination percentage and height of the seedlings, increase the total number and length of adventitious roots and root hairs, increase the hydraulic conductivity of the root system, increase in the height of the shoot and dry matter production and yield of the crop plants. The effect of Azospirillum inoculation on the total yield increases of field grown plants generally ranged from 10 to 30 per cent. This article reviews the recent researches on role of Azospirillum in plant growth promotion.

ABSTRACT

Plasmids are circular, double-stranded DNA molecules which replicate autonomously from the chromosome of the host organism. Plasmids are found in many bacterial species and often confer upon the host cell phenotypic characteristics such as resistance to antibiotics, resistance to heavy metals, ability to produce particular protiens, conjugative (mating) ability and ability to degrade xenobiotc compounds. One of these degradative plasmids may encode a complete catabolic pathway (such as toluene to pyruvate, formate and acetaldehyde) or partial degradative steps, such as octane to octanol. In this later case, the remainder of the pathway may be encoded by chromosomal genes, by genes of other plasmid present in the host, or by other microorganisms. Many degradative plasmids possess a broad host range, especially among the gram-negative bacterial species.

There are different mechanisms which may be involved in the evolution of aromatic pathways in general and in the process of adaptation of microorganisms to xenobiotic substrates in particular. Gene transfer, the occurrence of plasmids in bacteria in the natural environment is an important pool of genetic information residing on plasmid vehicles may flow among indigenous microorganisms. Since many examples of self-transmissible plasmids that carry genes for degradation of aromatic or other xenobiotic compounds are known, and their role in spreading these genes to other microorganisms is well characterized. Early, studies of TOL, NAH, and SAL plasmids revealed strong homologies among these plasmids in regions both inside and outside the catabolic gene clusters. Plasmids, pJP4, pAC25, and PSS50, catabolic plasmids carrying genes for chloroaromatic degradation, have strongly homologous plasmid backbone that determine replication and transfer function. Furthermore, the chlorobenzoate plasmid p51 was also shown to be homologous to pJP4 outside regions of the catabolic genes. These observations suggest that a few common self-transmissible ancestor replicons (includes origin of replication and replication gene) may have been involved in acquisition and spread of different catabolic genes.

Jay et al., (1995) and Joerger et al., (2003) have written the role of bacteriocins as an alternate to antibiotics. Bacteria produce bacteriocins which are proteinaceous in nature or peptidic toxins. These inhibit the growth of similar or closely related bacterial strain(s). There are different types of bacteriocins which are classified based on the producing strain, common resistance mechanisms and mechanism of killing. Ahmad et al., (2013) have isolated antifungal compound for food preservation. Martin et al., (2018) and Batish et al., (1997) found antibacterial compounds from fungus. Mahboubi et al., (2019) studied the potential of Zataria in IBS. There are bacteriocins from gram-positive bacteria known as the colicins, the microcins and the bacteriocins from Archaea (Cascales et al., 2007). The bacteriocins from E. coli are called colicins (formerly called ‘colicines,’ meaning ‘coli killers’). These have been studied widely. Earlier called colicin V and is now known as microcin V. It is very small and is produced and secreted in a different manner than the classic colicins. Adrienne et al., (2016) have studied the colicin resistance.

Introduction

Beekeeping is a vital component of agriculture and rural development programmes in various Asian countries. The great role of beekeeping in supplying nutritional, economic and ecological safety to rural areas of Asia cannot be ignored, as it has always been associated with their cultural and natural traditions. Beekeeping is a landless activity and does not compete with any other resource-intensive elements of farming systems. Beekeeping is an additional income-generating activity at the household level.

Introduction

At a present time, Organic farming has an important priority in different areas due to worldwide in look of the growing need for pure and nutritious agriculture food and keep up the feasible and environmental pollution on long time associated with indiscriminate use of chemical fertilizer. The use of synthetic inputs in crop cultivation is necessary to meet the growing need for agriculture food in world. The natural fertilizers are made containing living or veiled cells or their strains of N2 fixation, P2 O5 solubilization bacteria. The biofertilizers are used for seed cramming, soil or vermicomposting region with the objective of rising quantity of such microbes and further those microbial processes which augment the obtainability of nutrients that can be easily digest by plants. Biofertilizers are playing higher role in increase soil productivity by f ixing atmospheric nitrogen, both, in relationship with plant roots and without it, solubilise and insoluble soil phosphorus and produces many plant growth substances in the soil.

Introduction

Biopesticides are biological substances or plant-based products that are used for decreasing the number of pests in an ecosystem. These substances, which include natural enemies, microbial products, phytochemicals, and semiochemicals, are derived from plants and animals. Biopesticides use non toxic approaches to keep pests under control. They are widely recognised as low-risk items that are secure for both humans and the environment. It makes use of natural pest such as parasitoids, predators, nematodes, and semiochemicals as well as botanicals, microbiological pathogens like fungi, bacteria, and viruses.

Bio-stimulants are increasingly used to improve crop performance while reducing dependence on intensive chemical inputs. They include amino acids, protein hydrolysates, humic substances, seaweed extracts, beneficial microorganisms and plant- or microbial-derived compounds. These substances can influence root architecture, nutrient assimilation, hormonal balance, photosynthesis, stress tolerance and disease resistance. This chapter examines the effects of different bio-stimulants on onion seed germination, vegetative growth, bulb development, yield, quality and storage life. It discusses their modes of action, application methods and integration with nutrient-management programmes. Bio-stimulants are presented as promising components of environmentally responsible and resource-efficient onion production, while areas requiring further research are identified.

Introduction

Use of FYM, crop residues, leaf fall, root deposition etc. has been part and parcel in agriculture. These material undergoes microbial decay over the time slowly and the major portion of it finds way back to the atmosphere. Not only that, residue burning traditionally provides a fast way to clear the agricultural field of residual biomass, facilitating further land preparation and planting. However, in addition to the loss of valuable biomass and nutrients, biomass burning leads to release of toxic gases including GHGs.
