1. Introduction Millets, one of the earliest foods consumed by humans, may have been the first cereal grain utilised in domestic cookery. It belongs to the Graminae grass family. The name “millet” describes a number of little-seeded grasses (annual) that are classified into five genera: Setaria, Panicum, Pennisetum, Paspalum, and Echinocloa in the tribe Paniceae, and one genus: Eleusine in the tribe Chlorideae (Pushpavalli, 2015). India ranks first in the production of millets followed by Niger and China (FAO, 2020). Pearl millet (Pennisetum glaucum) serves as food, fuel, and fodder on a global scale. Since, it contributes up to 75% of all grain output in East Africa and several regions of India; it plays a significant role in indigenous diets. After rice and wheat, pearl millet is the third most significant crop farmed in India. Ninety percent of the country’s land is used for cultivating pearl millet, with Rajasthan, Gujarat, Maharashtra, Uttar Pradesh and Haryana being the main states.

Introduction

Quality is very important in any production and operation system. It ensures whether the products produced or the services provided are of the right quality in right quantity at right time. Quality management must ensure proper quality of the product to survive in the market and expand its market. Quality of the product must be given importance to avoid quality failures that cause serious human inconveniences and wastage of money.

5.1. Definitions and Terminologies

5.1.1. Quality

We say a product is of satisfactory quality, if it satisfies the consumers. According to C. D. Lewis, a British writer, quality is “an asset which is offered to the potential customer of that product or service”. The International Organization for Standardization (ISO) has put up a more comprehensive definition of quality as “the degree to which a set of inherent characteristics fulfils requirements” (ISO 9000: 2005 – 3.1.1). In general terms, ‘quality’ is defined as the composite of characteristics that differentiate individual units of a product to determine its acceptability by the customer. Quality characteristics are nothing but elements that makes a product fit for use. Quality characteristics are further classified into categories called as parameters.

5.1.2. Total Quality Management

Total Quality Management (TQM) is an organization’s management approach, centered on quality. It improves the effectiveness and flexibility of a company or an organization. TQM is defined as “the system of establishing defect prevention actions and attitudes with a company or an organization on a permanent basis for the purpose of assuring conforming products or services directed at customer satisfaction”. TQM is based on the participation of all its members in decision making, which is aimed for long-term success, through customer satisfaction and benefits to the members of the company or organization and to the society.

Introduction

The economic choice of any process is the criterion for efficient utilization of the by-product that is produced along side of main product. During manufacture of major dairy products, the dairy industry also ends up in producing different by-products. Various by-products of dairy industry are skim milk, butter milk , whey and ghee residue. Dairy industry is particularly confronted with the problem of economic utilization of whey and ghee residue. The techno-economical problems associated with utilization of these by-products, is now receiving considerable attention. More efficient, cost effective and sophisticated technologies have opened up new vistas for manufacture of number of derived by-products. Further more the market for dairy by-products, as an ingredients in other consumer food products like snacks, ready meals and microwavable food products, has been growing.

As rural populations decrease, so does the agricultural work force. In Europe and North America, agriculture now represents about 5% of the work force. In Africa and Asia, it is expected that the number of agricultural workers will have decreased from nearly 70% of the population in the 1980s to barely 50% by 2015 (Crop life International, 2010). The events of the past few years have highlighted the vulnerability of global food security to major shocks – both in the global agricultural markets and in the world economy. The food price crisis and the ensuing economic crisis reduced the purchasing power of large segments of the population in many developing countries, severely curtailing their access to food and thus undermining their food security. “We estimate that in 2012 there will be over a million children suffering from severe acute malnutrition – what’s important to know is that malnutrition can kill,” UNICEF’s Director of Emergency Programmes, Louis-Georges Arsenault, said in a news release. “We need more resources to really scale up our response before it becomes too late and too many lives are lost.” Sahel and other regions in the Horn of Africa are facing severe food crisis (UN, 2012). In such a condition, to feed the hungry mouths of the world, agriculture needs to be more modern and decisions should be information and knowledge based and not instinct-based. Information and communication technology has a great role to play here.

ABSTRACT

Panax L. is an important medicinal plant species complex, which is commonly known as ginseng. Ginseng has high commercial value for itsginsenoside contents and is collected from the wildin the subtropical-temperate forests of north-eastern India. Taxonomy, ecology and phenology of five species of Panax found in north-eastern India viz., P. assamicus R. N. Banerjee, P. bipinnatifidus Seem., P. pseudoginseng Wall., P. variabilis J. Wenand P. sokpayensis Sharma& Pandit, have beendiscussed in this paper. The distribution of these species is restricted to the states of Arunachal Pradesh, Manipur, Meghalaya, Nagaland, Sikkim and Darjeeling HillsofWest Bengal.P. pseudoginseng hasextended distribution range in Nepal. P. variabilis was reported from Nagaland, which is a new record for India. All the species of Panax prefer shady and moist habitat. The species grow in the soil texture that ranges from loamy sand to sandy. The pH ranges from 4.3-7.1. The species is perennial and pereniates through its underground rhizome. The phenophase starts with emergence of seedlings in the late March and senescence takes place in the middle of October after seed setting. Monitoring of the populations of all Panax species revealed that the population size have decreased by 40-50% over a period of 10 years due to over-harvesting from the wild by the local people for its medicinal value. Sustainable use of rhizome and its cultivation practice need to be standardized to address the conservation issues related to the plant.

Abstract
Climate change significantly impacts the aquaculture industry, threatening productivity and food security. Rising temperatures, ocean acidification, extreme weather events, and shifting habitats disrupt species’ growth, survival, and reproductive cycles. This chapter explores climate-smart aquaculture (CSA) as a response, which focuses on sustainable practices to enhance resilience and mitigate climate change effects. CSA strategies include the selective breeding climate-resilient species and using advanced technologies like integrated multitrophic aquaculture (IMTA) to reduce environmental stress. These methods help maintain aquaculture productivity while reducing climate-related vulnerabilities. Adopting spatial technologies, including satellite remote sensing and site-suitability models, allows identifying optimal aquaculture sites less susceptible to climate impacts. Furthermore, disaster relief programs and insurance provide financial protection against the effects of climate-related losses, offering support during extreme events such as storms and algal blooms. Implementing these climate-smart practices is crucial to ensuring aquaculture’s sustainability and long-term viability, helping to secure global food systems in the face of a changing climate.

12.1 Chi-Square Variate
The square of a standard normal variate is known as a chi – square variate or chi square statistic with one degree of freedom.

Over the past several years, there has been significant change in consumer perception on quality and food safety. Consumers are demanding healthy, nutritious and cost-effective products processed under controlled hygienic conditions. Food safety concern, in recent years, has become dominant and important. The requirement of food safety and quality assurance has never been so demanding as it is now. Globally food safety is being addressed independent of food quality. In anticipation of consumer demands on food safety, food sanitary standards at national and international levels are under constant review. Several inter governmental agencies/organizations are engaged in work related to quality assurance and food safety. Amongst these World Health Organization (WHO) and Codex Alimentarius Commission (CAC) play the major role in protecting public health and defining standards of quality and safety aspects of foods for regional and or world wide usage.

INTRODUCTION

Heterosis has contributed significantly towards increased crop production and it has become the basis of multibillion dollar agro-businesses in the world (Phillips, 1999). Hybridization is the important way that can create genetic variability and make new options. The F1 population is obtained from the crossing of two homozygous but genetically dissimilar gametes or individuals (purelines in self pollinated crops or inbred lines in cross pollinated crops) that shows increased or decreased vigour over the better or mid parent value. Heterosis is maximum in F1, generation which diminishes gradually in later generations. Hence, production of F₁, hybrid seeds of different flower crops is considered as the extreme focused area in floriculture industry.

Dahlia (Dahlia spp.) syn. Georgina belongs to family Compositae (Asteraceae). Dahlia was named after “Professor Andreas Dahl”, a Swedish pupil of Linnaeus and author of Observations Botanicae. In India, dahlia is grown as potted plant and landscape uses but it is a poor crop as commercial flower due to shorter commercial life and its potentialities have not been exploited so far. Therefore, there is need to originate more and more new quality cultivars. Dahlias are half-hardy perennials with tuberous roots. Stems are mostly erect, branched, glabrous or scabrous. The leaves 1-3 pinnate, with slightly serrated margin are produced opposite at each node on the stem. They bear flowers on a long, stiff stems well above the foliage. Ray florets are neutral or pinnate and disc florets perfect.

ORIGIN AND DISTRIBUTION

The wild species of Dahlia are natives of Mexico and Central America, where some hybridization and selection had probably already occurred prior to their introduction into Europe at the end of the 18^th century (Crane et al., 1947 and Sorensen, 1969). The dahlia has been in Europe for over 200 years. It came from Mexico to the Botanical Gardens in Madrid towards the end of the 18^th century and was named by Abbe Cavanille in honour of Andreas Dahl, Swedish scientist-cum-environmentalist. The dahlia was introduced into England in 1803, but from a few varieties it soon had more than 300 varieties within the first 15 years. The initial named species imported into Europe were D. pinnata, D. rosea and D. coccinea. The first dahlias grown outside of Madrid were single (open-centred) and multi-ray open centre flowered, but it was not long before the horticultural growers of the day discovered the dahlia was a natural hybrid and when grown from seed, it readily changed its form and colour, Thus it has a range of different types. Further introduction, accompanied by hybridization and selection, have resulted in the production of a wide range of flower, forms and colours. Most of the garden types have been developed from D. variabilis. The first double flowered varieties were called Show and Fancy types. The show were self-coloured, ball like flowers, while the Fancy ones were multi-coloured.

During the mid 1800’s, these Show and Fancy flowers attained cult status with gardeners and several thousand different varieties were recorded. Other forms followed, in 1829 the first Anemone flowered dahlia appeared and then in 1850 the first Pompon was raised in Germany and was named after the bobble on a French sailor’s hat. The origin of the cactus and Decorative type belongs to the arrival of ‘Juarrezii’. According to the written records it was important as a piece of tuber from Mexico in 1872 to Holland. M. Van de Berg of Uttrecht received this so called species from Mexico and released stock of the variety in 1874. Subsequently, ‘Juarrezii’, named after a President of Mexico, was introduced into the UK by W. Cullingford a Vice President of the NDS and distributed by H. Cannell after 1880. Collerettes are the last form of dahlia to have been raised, that has their origin in France and is due to sporting of dahlias at Jardin Botanique de Lyon at the end of the 19^th century.

1.1 Introduction

Greenhouse effect, regulated by the presence of greenhouse gases in the earth’s atmosphere, is a natural process that plays a major part in shaping the earth’s climate. A continued rise in concentration of the greenhouse gases has led to enhanced greenhouse effect resulting in global warming and global climate change. The impact of human activities on greenhouse gases (GHGs) emission through fossil fuel burning, agriculture and industrial processes is important and familiar to people. This chapter addresses basic principles and physics of greenhouse effect and the role of Indian agriculture in GHG emissions. Agriculture is a potential source and sink to GHGs in atmosphere. It is a source for three primary GHGs: CO₂, N₂O and CH4 and sink for atmospheric CO₂ . Management of agricultural land, land use change and forestry has a profound influence on atmospheric GHGs concentration. The two broad anthropogenic sources of GHGs emission from agriculture are the energy use in agriculture (manufacture and use of agricultural inputs and farm machinery) and the management of agricultural land. Large sections of the India’s population depend on biomass resources like wood, crop residues and cattle dung for energy. In the agriculture sector, besides the CO₂ emissions due to burning of crop and animal waste, India’s large ruminant population and rice fields are significant contributors to CH₄ emissions. An understanding of GHG emissions by sources and removal by sinks in agriculture is important to take appropriate mitigation and adaptation strategies and to estimate and create inventory of GHGs.

Introduction

According to the Intergovernmental Panel on Climate Change, climate change refers to the long-term changes (typically decades or longer) in the average state of the climate with statistically significant variations.

The climate change, defined as the long-term imbalance of customary weather conditions such as temperature, radiation, wind and rainfall characteristics of a particular region, is likely to be one of the main challenges for mankind during the present century.

A general definition of climate change is a change in the statistical properties (principally the man and spread) of the climate system when considered over long periods.

Climate Resilience

Climate resilience can be generally defined as the capacity for a socioecological system to: Absorb stresses and maintain function in the face of external stresses imposed upon it by climate change. Adapt, reorganize, and evolve into more desirable configurations that improve the sustainability of the system, leaving it better prepared for future climate change impacts.

Introduction
Farm mechanization represents a pivotal shift in agricultural practices, marking the transition from traditional, labor-intensive methods to modern, technologydriven farming systems. This chapter explores the various dimensions of farm mechanization, highlighting its critical role in enhancing agricultural productivity, ensuring food security, and addressing the challenges of global warming. The chapter begins by examinin65g the different types of agricultural machinery and equipment used in modern farming. This includes tractors, plows, harvesters, seeders, and other essential tools that have revolutionized the way crops are cultivated, harvested, and processed. The mechanization of these processes has significantly increased efficiency, reduced labor costs, and improved the overall productivity of agricultural systems. Precision farming and remote sensing are discussed as integral components of modern farm mechanization. These technologies enable farmers to optimize the use of resources such as water, fertilizers, and pesticides, thereby increasing yields while minimizing environmental impacts. Key components of precision farming, such as GPS-guided machinery, soil sensors, and aerial imaging, are explored in detail, along with their applications and benefits. The chapter also delves into machinery management and maintenance, emphasizing the importance of regular upkeep and proper management of farm equipment. Effective machinery management ensures the longevity and reliability of agricultural machinery, reduces downtime, and lowers operating costs, all of which contribute to more sustainable and profitable farming practices. Farm mechanization is highlighted as a crucial factor in enhancing food security. By increasing the efficiency and scalability of food production, mechanization plays a vital role in meeting the growing global demand for food. The chapter discusses how mechanization extends growing seasons, improves crop quality, and diversifies crop choices, thereby contributing to a more stable and resilient food supply. The impact of farm mechanization on global warming is also a key focus of this chapter. While mechanization has led to increased productivity, it has also contributed to greenhouse gas emissions and other environmental challenges. The chapter explores strategies for mitigating these impacts, including the adoption

Introduction 
Renewable and more eco-friendly sources of fuel must be a major concern of our nation for the betterment of our environment because a growing population requires more energy. Fossil fuels have played a significant role in driving the advancement of society, economy, and development. Fossil fuels are the most used sources for the fulfilment of energy requirements. The predominant source of energy on a global scale is fossil fuels, which account for 88% of total energy production (Li et al., 2019). These sources are finite and depleting sources and have a significant negative impact on the environment through the emission of greenhouse gases, sulfur dioxide, nitrogen oxide, and particulate matter (Ritchie et al., 2023). These gases cause global warming by trapping heat, which causes climate change and its side effects, such as increased temperatures globally, more frequent and intense heat waves, and altered weather patterns (Solarin, 2020). In 2017, there was a 1.6% increase in CO2 emissions related to the combustion of fossil fuels, and this trend is anticipated to continue (Khoo et al., 2020). Fossil fuels, on the other hand, are non-renewable sources of energy that will deplete rapidly within fifty years (Chew et al., 2018). In an age marked by increasing environmental concerns and a growing urgency to combat climate change, the pursuit of sustainable and eco-friendly energy sources has never been more critical. Among the renewable energy options, biofuels have emerged as a prominent contender, holding the promise of reduced carbon emissions and a path toward a greener, more sustainable future (Takeuchi et al., 2002). Biofuels, derived from organic materials like trees algae, and waste, have attracted a lot of attention because they have the potential to lessen our reliance on fossil fuels and reduce the negative effects of climate change. Figure 5.1 shows the classification of biological feedstocks utilized in biofuels comprising four distinct generations: first, second, third, and fourth (Alalwan et al., 2019). Edible biomasses like sugar beet, corn, wheat, rice corn, etc come under the category of first generation. Since these feedstocks are in competition with food harvests for a specific quantity of land, fertilisers, and water, the viability of first-generation biofuels is subject to discussion (Paschalidou et al., 2016). Subsequently, the resources and energy utilised in the cultivation of feedstocks are inefficiently utilised, resulting in costly production. Furthermore, there exists a discourse surrounding the potential contribution of biofuel to the mitigation of greenhouse gas emissions (GHGs). This is because certain biofuel varieties may generate negative net energy gains, thereby increasing greenhouse gas emissions throughout the production process. However, the most contentious topic continues to be the "food versus fuel" dilemma.

Terms associated with cropping and farming systems are:

1. Cropping system: is an important component of a farming system. It represents cropping pattern used on a farm and their interaction with farm resources, other farm enterprises and available technology which determine their makeup.
2. Cropping pattern: means the proportion of area under various crops at a point of time in a unit area. It indicates the yearly sequence and spatial arrangement of crops and fallow in an area.
3. Cropping scheme is a plan according to which crops are grown on individual plot of a farm during a given period of time with the object of obtaining maximum return from each crop without impairing soil fertility. Thus a cropping scheme is related to the most profitable use of resources, land, labour, capital, and management.
4. Multiple cropping: Growing two or more crops on the same piece of land in one calendar year is known as multiple cropping. It is intensification of cropping in space and time dimensions. It includes intercropping, mixed cropping and sequence cropping.
5. Quadruple cropping: Growing of four crops in a year in sequence.
6. Competition effect: Competition of intercropped spp. For light, nutrients, water, carbon dioxide, and other growth factors.
7. Complementary effect: Effect of one component on another which enhances growth and productivity.

Introduction

In all countries, food is governed by a complexity of laws and regulations, which set out the Government requirements to be met by food chain operators to ensure food safety and quality. Food laws and regulations also govern standards that ensure the safety, quality, composition and suitability of food for consumers. Food laws and regulations of any nation depends on whether a nation adopts International norms developed by the Codex Alimentarius Commission (CAC) of the Food and Agriculture Organization (FAO) of the United Nations as well as the World Health Organization (WHO).

8.1. Food Laws

Food law means legislation that regulates the production, trade and handling of food. It covers the regulation of food control, food safety, quality and relevant aspects of food trade across the entire food chain, from the production to the consumer. Food laws protect the consumers against unsafe, adulterated and misbranded food and facilitate the movement of food across borders to sustain a fair trade.

Each nation administers its own laws, regulations and standards. It is also not static always and is constantly revised and updated in all nations. The food business operators (FBO) must obtain up-to-date information on any changes made in legislation, that are likely to affect the product standards. The regulations of all nations shall be obtained from their respective websites of the national ministries.

8.1.1. International Legislations

8.1.1.1. United States of America (USA)

In USA, the Food and Drug Act (1906) and the Federal Meat Inspection Act (1906) are the first federal food laws passed to protect American consumers. Later, Food, Drug and Cosmetic Act (1938) regulated the meat and poultry products. At present, Food Safety Modernization Act (FSMA), 2011 regulates all food products. https://www.fda.gov/food/guidance- regulation- food- and dietary- supplements/ food- safety- modernization- act- fsma. Manufacturers play important role in preventing food borne illness. The Act gave the Food and Drug Administration (FDA) the authority to oversee and enforce supply chains. The Act shifts the focus towards prevention of food borne illness and insists every FBO to register with the FDA.

Abstract
As global food security becomes increasingly urgent, high-density aquaculture systems present a viable solution to meet the rising protein demands of the world’s growing population, projected to reach 9.8 billion by 2050. This chapter examines the integration of various innovative aquaculture techniques designed to improve the sustainability and efficiency of fish farming. High-density systems such as recirculating aquaculture systems (RAS), biofloc technology (BFT), cage culture, integrated multi-trophic aquaculture (IMTA), flow-through aquaculture systems (Raceways), hybrid systems, and vertical farming are explored for their potential to optimize production while minimizing resource consumption. The chapter highlights the critical role of stocking density in improving system performance, influencing factors such as growth rates, water quality, and overall resource use. IMTA, which combines fed species with extractive organisms like seaweeds and shellfish, facilitates nutrient recycling, promoting environmental sustainability and enhanced productivity. Hybrid systems, including Partitioned Aquaculture Systems (PAS) and Bio-RAS, integrate traditional and advanced technologies to overcome the limitations of conventional methods, enabling high-density production with reduced environmental impact. Additionally, vertical farming and aquaponics are examined as complementary strategies, integrating fish farming with plant cultivation to create sustainable, resource-efficient models suitable for urban settings. Through a comprehensive analysis of species selection, stocking densities, and system design, this chapter illustrates the potential of high-density aquaculture as a critical contributor to global food security, reducing pressure on wild fish stocks and promoting long-term environmental sustainability.
Keywords: High stocking density, maximize production, economic viability, environmental sustainability

Introduction
Biotechnology represents a transformative force in modern agriculture, offering innovative solutions to enhance crop production, improve resistance to diseases, and address the global challenges of food security and climate change. Chapter 9 delves into the multifaceted role of biotechnology, particularly in the realm of genetic innovation, and how it is reshaping the agricultural landscape. The chapter begins by exploring the various applications of biotechnology in crop improvement. This includes the development of genetically modified organisms (GMOs) and transgenic crops, which have been engineered to exhibit desirable traits such as increased yield, pest resistance, and enhanced nutritional content. These advancements have significantly contributed to the global food supply, particularly in regions facing harsh climatic conditions or limited agricultural resources. A detailed examination of genomic tools and techniques follows, highlighting the sophisticated methodologies employed in biotechnology. Techniques such as CRISPR -Cas9 gene editing, marker-assisted selection, and genomic sequencing are discussed, showcasing their pivotal role in accelerating the development of improved crop varieties. These tools have enabled scientists to manipulate genetic material with unprecedented precision, paving the way for more efficient and targeted crop breeding programs. The chapter also addresses the role of biotechnology in crop protection, emphasizing its importance in developing crops that are resistant to pests, diseases, and environmental stresses. By enhancing the natural defense mechanisms of plants, biotechnology reduces the need for chemical pesticides, thereby promoting more sustainable agricultural practices and minimizing the environmental impact of farming. The importance of biotechnology and genetic engineering in ensuring food security is a central theme of this chapter. As the global population continues to grow, the demand for food is expected to increase dramatically. Biotechnology offers a viable solution to meet this demand by enabling the production of higheryielding and more resilient crops. This section also explores the ethical and regulatory considerations surrounding the use of GMOs and other biotechnological innovations in agriculture.

INTRODUCTION

The seed (or zygotic seed) is the vehicle that connects one generation to another in much of the plant kingdom. By means of seed, plants are able to transmit their genetic constitution in generations and therefore seeds are the most appropriate means of propagation, storage and dispersal. A synthetic seed or ‘synseed’ is “an encapsulated single somatic embryo”, i.e., a clonal product that can be handled and used as real seed for transport, storage and sowing and that, therefore, would eventually grow either in vitro or ex vitro, into a plantlet through a process of “conversion”. Now a day, artificial seed technology is one of the most important tools to breeders and scientists of plant tissue culture.
