Introduction

In every industry main running factors are as Manpower, machine, material and money.

Money is main big factor for capital expenses as well as operating expenses. Beside this other driving force are man power who installed and run the any industry based on their skill level.

Every organization has their own organization structure to manage industrial operation based on product variant like market milk, curd, paneer, buttermilk, butter & ghee, ice cream etc. Basic dairy plant organization structure is shown in below table and HR department mainly keep in mind to recruit them based on functional requirement, educational qualification, professional experience etc.

Based on above manpower requirement and product variants, processing cost to be worked out.

Recruitment of Manpower

Manpower is major key component of any industry/organization to run efficiently. The dairy industry, being one of the most vital sectors of the global agricultural economy, relies heavily on a skilled and efficient workforce to sustain its operations. Manpower’s involvement starts from milk production at farm level to processing and marketing of value-added dairy products, every stage to ensure quality, productivity and compliance with industry standards. Recruitment and training of manpower, therefore, play a primary role in addressing the challenges of modern dairy operation, including technological advancements, quality assurance, and sustainability.

The concept of recurrent selection grew out of need to increase the number of superior genotypes that could be obtained from breeding stock of corn. This could have been possible by increasing the frequency of superior genes in the gene pool and by increasing the chances for genetic recombination to occur. Both can be achieved by recurrent selection which is defined as “a method of breeding designed to concentrate favourable genes scattered among a number of individuals by selecting in each generation among the progeny produced by mating inter se of the selected individuals (or their selfed progeny) of the previous generation.” The original idea behind recurrent selection was proposed first by Hayes and Gerber in 1919 and independently by East and Jones in 1920. Jenkins (1940) was the first to describe the method in detail and Hull (1945) proposed the name ‘recurrent selection’. Each cycle of recurrent selection requires (i) evaluation and selfing of selections and (ii) crossing of the progenies of superior selfed plants in all combinations and bulking of equal amount of seed from each cross. The selection of plants before selfing is possible for maturity, plant height, ear/head characters, kernel characteristics and resistance to diseases and insects. In general, these are the characters which have high heritability. It is clear that the selection of plants before selfing is more for morphological traits and these evaluations do not include yield. Yield evaluations are done on the top cross progenies (crossing of selected plants to a tester). Such top crosses will be grown in the second year of the cycle during which time the selfed seed is held over until the evaluations for yield are over. Or the selfed seed may be grown out as S₁ lines which in turn are selfed. After yield evaluation is over, the selfed seed of superior plants is grown out for crossing. Progenies of selfed plants are crossed in all possible combinations. This is done manually or by growing progenies together in an isolated block. In isolation planting, random mating should be ensured. After manual crossing or random mating in isolation, equal amounts of seed of each are bulked and this bulk seed is used to start the second cycle of selection, selfing and crossing.

Recurrent selection is a method of breeding applicable to cross-pollinated crops, designed to concentrate favourable genes scattered among a number of individuals by selecting in each generation among the progeny produced by mating inter se of the selected individuals (or their selfed progeny) of the previous generation.

1.1. FYM compost

Decomposed mixture of dung and urine of farm animals along with litter and left over materials from roughages or fodder fed to the cattle.

Farmyard manure contains 0.5% N, 0.2% P₂O₅ and 0.5% K₂O.

Urine contains one per cent nitrogen and 1.35% potassium.

10 to 20 t/ha is applied, but more than 20 t/ha is applied to fodder grasses and vegetables like potato, tomato, sweet potato, carrot, radish, onion etc., respond well to the farmyard manure.

Crops like sugarcane, rice, oranges, banana, mango and coconut respond good to FYM.

The term animal waste comprises, the fresh excrement, including both solid and liquid excreta and urine. * It also includes the bedding material, animal washings, feed waste and straw which are having considerable manorial value. * The characteristics of the livestock wastes depend on fractions of the digestibility, composition of feed ration and species of animals and their physiology. * The waste ruminants have different composition than obtained from swine and poultry, which is having high nutritive value.
For fodder production, the animal waste can be utilized in many ways, that is, as pesticide and that is, as non – conventional source of source energy as pesticides bio – fertilizer to improve soil fertility for sustainable agriculture. This livestock waste can be recycled in following ways: Organic mulch, As pesticides, In organic farming, Biogas production, Composting, Vermicomposting, Profitable manure management by livestock fish integration.

Crop residues are valuable natural resources that may be managed to maximize various input use efficiencies. These are a great source of organic materials for improving the soil structure, water holding capacity, the soil's ability to withstand pH variations, increasing the cation exchange capacity, reducing the phosphate fixation, as a storehouse for micronutrients and secondary nutrients especially in organic farming. Organic matter serves as a source of energy for soil fauna and microbes, which are the main agents controlling the decomposition and release of mineral nutrients in organic soil ecosystems. Crop leftovers are frequently burned by farmers, especially after harvest, which depletes the soil's nutrient content and microbial population and produces greenhouse gases. Each year, a sizable amount of crop residue is produced and if used efficiently, they may provide partial or full amount of the nutrient budget required under organic farming for the production of annual or perennial crops besides achieving resource conservation and environmental sustainability.

1. Introduction

Crop residues are the non-economic plant parts like straws, stubble, stover etc., that remain in the field after harvesting the economic product. Crop remains from threshing sheds such as groundnut shells, oil cakes, rice husks, corn and sorghum cobs or discarded during crop processing can also be utilized in organic farming. India produces 108.75 MT of wheat, 121.46 MT of rice seed, 30.24 MT of maize seeds, 49.66 MT of millets seeds (jowar, bajra, ragi, and small seed millets), 392.8 MT of sugarcane, 46.11 million bales of fibre crops (jute, mesta, cotton), 25.58 MT of pulses and 36.57 MT of oilseed (Agricultural statistics at a glance, 2021).

Abstract

Recycling of organic wastes by chemical amendments and bio-inoculants are the recent developments in the technology for composting to manage voluminous wastes with economic advantages as well as environmental and social perspectives. Various composting technologies such as vermicomposting, P-enriched vermicompost, phospho-sulpho-nitro compost, phosphocompost and microbial enriched compost have been developed utilizing agro-industrial wastes, municipal solid wastes, distillery effluents and press mud, amended with certain mining waste materials such as rock phosphate and pyrites for increasing the nutrient supplying potential of the compost. It was observed that matured enriched compost (after 110 days of composting) contains 3.2 to 4.2% P and 1.5 to 2.3% N. In vermicomposting, earth worms helps in accelerating the decomposition processes and bringing down the composting period from six to eight months to around 2-3 months. Thus, enriched compost helps to produce higher yields of crops and also improve soil physical, chemical and biological conditions, thereby, enhancing productivity and sustainability of agriculture.

14.1. Introduction

There is a tremendous need to change the way society produces, and consumes materials to manage the environmental effect in the growing scarcity of resources. To overcome this issue, recycling process could be a great possibility that reduce the uses of natural resources, maximizethe waste utilization and produce least environmental impact. Unfortunately, packaging materials contribute 40% of solid waste in Western Europe, and 33% in US. In fact, packaging waste is likely to increase in transitioning and developing countries. Recycling process consists of collection, sorting, recovery, and management of packaging materials. As per the report of “Eurostat statistics in 2018”,European Union (EU) generates 174.1 kg of packaging waste per inhabitant, Croatia contributes 67.8 kg per inhabitant and Germany produce 227.5 kg per inhabitant.

16.1 Conservative Technology

Recycling technology being practiced by ancient times by the people who used for municipal industrial effluent. In India the people in rural area, they collected cow dung in a pit. They applied a layer of soil on the cow dung to composting. After three to four months period, they used as manure for the agricultural fields. In a household waste, they collected as organic waste from a kitchen, store a pit allow it for decompose for conversion of compost. People who are residing in house constructed in a plot, they used to generate industrial effluent in a pit and cultivate a kitchen garden like vegetable crops and banana trees etc. in ancient times, the amount organic waste is limited and self purification is taken in small amount of organic waste therefore no organic pollution occurs in rural India.

According to Planning Commission Report (2014), India generates about 62 million tons of municipal solid wastes (MSW) every year from urban cities. There has been a significant increase in municipal solid waste generation in India in the last few decades. This is largely due to rapid population growth and economic development in the country (Annepu, 2012). Solid waste management (SWM) has become a major environmental issue because of serious environmental implications like global warming (through green house gases emission) and contamination of toxic pollutants (like heavy metals) in surface and groundwater bodies. Solid waste management is one of the essential services to be provided by municipal authorities in the country to keep urban areas clean. Out of total waste generated in India, only 12.45% waste is scientifically processed and rest is disposed in open dumps (CPCB Report, 2013). Although, incineration of solid wastes is being followed in many places for energy production, composting is considered most environment friendly method of SWM as it promotes recycling of nutrients in crop production.

Introduction

The process of recycling involves the conversion of waste materials into reusable products or materials and aims to reduce the consumption of fresh raw materials, minimize energy use, and mitigate trash creation. The primary objective of recycling is to effectively preserve finite resources, safeguard the natural environment, and mitigate the volume of garbage deposited in landfills or subjected to incineration (Lienig et al., 2017). Recycling refers to the systematic transformation of discarded materials into fresh resources and tangible products. The aforementioned term often encompasses the process of extracting energy from waste materials. The recyclability of a material is contingent upon its capacity to regain the characteristics it has in its initial form. There exists an alternative approach to garbage disposal that has the potential to save resources and mitigate the release of greenhouse gases. Additionally, it can mitigate the waste of potentially valuable resources and diminish the use of pristine raw materials, therefore reducing energy consumption, air pollution resulting from incineration, and water pollution stemming from landfill practices. The promotion of environmental sustainability is achieved by the removal of raw material input and the redirection of waste output within the economic system. The increasing volumes of trash have given rise to several environmental challenges, including air pollution, water pollution, soil contamination, and biodiversity loss. The emission of diverse greenhouse gases from solid waste landfills also contributes to the phenomenon of global warming. At now, the predominant techniques for solid waste disposal are open dumping and landfilling. Various alternative techniques, such as pyrolysis, gasification, anaerobic digestion, composting, and bio-methylation, are used to extract valuable resources from solid waste materials (Griffin et al., 2018).

Educational content development traditionally requires substantial time and effort from teachers, instructional designers, and academic institutions. Generative AI is changing this process by enabling the rapid creation, adaptation, personalization, and transformation of learning materials. This chapter examines how GenAI can redesign educational content generation across different subjects, educational levels, and learner requirements. It explores automated lesson-plan generation, question-bank development, personalized learning materials, visual and interactive resources, simulations, and multimodal educational content. AI systems can generate explanations at different levels of complexity, create assessments aligned with learning outcomes, and adapt instructional materials to student performance. Such capabilities can support differentiated instruction, self-paced learning, and improved learner engagement while reducing repetitive preparation work for educators. The chapter also examines important challenges, including content accuracy, algorithmic bias, copyright, data privacy, academic integrity, and teacher readiness. Future possibilities include adaptive tutors, multimodal content generation, AI-supported curriculum design, and intelligent learning resources. Overall, the chapter emphasizes that GenAI should augment professional educational judgment rather than replace it.

11.1 INTRODUCTION

Citrus as a perennial crop occupies globally a place of prime importance amongst major fruit crops including India. The cultivation of citrus in India is dominated by three major cultivars viz., mandarin, sweet orange, limes and lemons occupying collectively an area of 9.23 lakh ha with a production of 86.08 lakh tonnes and productivity of 9.3 tonnes/ha. Nagpur mandarin in India is grown in 0.97 lakh ha area with total production of 8.81 lakh tonnes and productivity of 9.l tonnes/ha, respectively. The productivity of mandarins within the country is highly variable in space and time, the major constraint is inadequate and unbalanced fertilizer use. The commercial cultivation of Nagpur mandarin is extensively confined along the Satpuda foothills of central India comprising Chindwara region of Madhya Pradesh and Vidarbha region of Maharashtra. The nutrient demand is highly variable in space (due to heterogenous soils) and time (due to varying weather conditions). Therefore, determination of crop nutrient requirement is a subject of great complexity. Experiments have shown that soils initially rich in fertility developed a variety of nutrient constraints following the non-synchronisation in demand and supply of nutrients with the orchard age (Srivastava et al., 1998). For example when exchangeable K is not rapidly replenished, crops start drawing on the non-exchangeable K, resulting in soil mining and depletion in soil K reserve. A nutrient level sufficient for one particular productivity level may not hold sufficient for other higher productivity levels. An extensive survey of 18,000 ha area of Nagpur mandarin orchards of central India showed large scale deficiency of three nutrients viz., N, P and Zn, with most of the sites expressing multiple nutrient deficiencies (Srivastava and Singh 2002; 2005). Reduced longevity of commercial citrus orchards due to varying nutritional constraints is one of the major production related constraints highly responsible for poor orchard efficiency (Srivastava and Singh, 2008a; 2008b).

Pets provide companionship, emotional support, and numerous health benefits to their owners. However, they can also be carriers of zoonotic diseases— diseases that can be transmitted from animals to humans. Understanding these risks and implementing measures to reduce them is crucial for maintaining the health and safety of both pets and humans. This article explores common pet-associated zoonotic infections and offers strategies to minimize the risk of transmission.

Common Pet-Associated Zoonotic Infections

1. Rabies

• Cause: Rabies is caused by the rabies virus and is transmitted through the bite of an infected animal.

• Symptoms in Humans: Initial symptoms include fever and headache, progressing to neurological symptoms such as confusion, hallucinations, and paralysis. Rabies is almost always fatal once symptoms appear.

• Prevention: Vaccination of pets, avoiding contact with wild animals, and immediate medical attention after potential exposure.

Abstract
The growing global population has intensified farming practices, increasing the use of fossil fuels and agrochemicals. With limited land and the need to enhance food production, balancing environmental impact, especially carbon footprints, is crucial. Climate-smart mitigation options, with a prime emphasis on crop diversification, can help agriculture adapt to anomalous weather patterns and build resilience. Legumes offer a sustainable solution by reducing greenhouse gas emissions, as they produce 5-7 times less gases per unit area compared to other crops. They aid in carbon sequestration, with soil carbon estimates of 7.21 g kg-1 of dry matter, and save fossil energy by decreasing nitrogen fertilizer use, reducing CO2 emissions by 277 kg ha-1 per year. Legumes play a key role in low-emission farming systems due to their ability to fix atmospheric nitrogen, reducing dependence on energy-intensive synthetic fertilizers. They improve soil health, enhance soil structure, and support carbon sequestration. Integrating legumes into crop rotations reduces the need for chemical pesticides and fertilizers. Additionally, legumes can be used in food, feed, and biofuels, lowering reliance on more carbon-intensive resources. Embracing legumes in farming systems promotes sustainability improves soil health, and considerably reduces the overall environmentalimpact of agriculture.

Yield gap of a crop is the difference between the maximum yield under optimum management condition and the average yield achieved by the farmers. Yield under optimum management condition is otherwise known as potential yield of the crop. Because of concerns about global food security problem of malnutrition, there is necessary to minimize the yield gaps in order to enhance food production within limited resources. This will reduce vast majority of undernourished population residing in under-developed countries. Assessment of potential yield and the gap between potential and actual yield is very much necessary before any investment for improving crop production (Nanda and Sahoo 2010).

Chemicals have been in use to arrest the ill effects of plant diseases even in the prehistoric periods (1000 B.C.) (Ogawa et al. 1977), although the nature of the causative agent was not known at that time. A combination of chemicals was developed and demonstrated to be effective against the devasting downy mildew disease affecting grapevines by systematic investigations of Millardet (1882) in France. This mixture of copper sulphate and lime was named as Bordeaux mixture after the place where it was developed (Large 1940). Despite the development of hundreds of chemicals over the following decades, for the management of fungal diseases, Bordeaux mixture is still being used against certain diseases. Copper, sulphur - and mercury-based compounds were applied prior to the 1940s. After the end of World War II, several organic chemicals were released into the market to wage a losing war against the plant pathogens. The researchers and industry have now realized that microbial pathogens cannot be entirely suppressed or eliminated by chemicals or by any other means.

Methods of crop disease management are based on the principles of exclusion, eradication and immunization. Various methods of excluding the pathogens primarily through establishing plant quarantines and production of disease-free seeds and asexually propagated planting materials have been discussed earlier (Chapter 8). The pathogens that have been introduced and those that have established in a geographical location have to be eradicated by employing different methods for removal of infected plants, plant debris and alternate and alternative host plants for reducing pathogen inoculum and consequent reduction in disease incidence. Other methods may be broadly divided into two classes as chemical and nonchemical methods. The chemical methods involve the use of chemicals that may act indirectly by creating conditions unfavourable for the development of the disease (Chapter 9) or chemicals that have direct inhibitory activity on the pathogens (Chapter 11). Pathogen populations may be kept under check by adopting cultural practices either alone or in combination with chemical and nonchemical methods (Chapter 10). Biological agents have been employed for reducing pathogen inoculum or for inducing resistance in host plants resulting in different degrees of reduction in disease incidence. The methods involving the use of biological agents as a strategy of crop disease management are discussed in this chapter.

Biological control methods aim to reduce the pathogen inoculum or disease producing activity of a pathogen by employing live microorganisms or using products of biological origin. Use of antagonistic microorganisms, avirulent strains of pathogens, cross-protection induced by mild strains of pathogens in susceptible host plants and induction of resistance in the susceptible crop cultivars are some of the approaches made to reduce the adverse effects of infection by microbial pathogens.

Crop husbandry includes various cultural practices aimed at enhancing yields from a given unit of land. To achieve this aim, practices such as growing high yielding cultivars which are fertilizer responsive, high density planting and application of large quantities of different nutrients and frequent application of pesticides have been followed. Consequently these practices have been found to be responsible for some problems which were not associated with crops raised by adopting traditional agricultural practices. Thus the benefits of modern methods appeared to be lost, because of the unforeseen problems for which the effective solution have to be found out. Various methods that could be dovetailed with regular cultural practices have been shown to be useful in either reducing the existing pathogen inoculum or avoiding build up of inoculum in the field.
