12.1. BASIC AND CURRENT FACTS OF AGRICULTURE

Basic information related to agriculture and allied sciences in India

Gladiolus (Gladiolus spp.) belongs to family Iridaceae and subfamily Ixioideae. Gladiolus is a Latin word, the diminutive of “gladius” meaning sword, sometimes called as sword lily. The plant is herbaceous perennial and semi-hardy. It is commonly grown from rounded, symmetrical corm, which is enveloped in several layers of brownish, fibrous tunics. The cultivated gladiolus is a complex assemblage of cultivars originating from complex ancestry of natural selection or hybridization involving several species. Modern garden gladiolus is a complex of at least twelve species (Raghava, 2000). It is an important commercial cut flower in both domestic and international markets.

ORIGIN AND DISTRIBUTION

There are two main centres of distribution of Gladiolus species, one in Mediterranean basin and the other in southern and central Africa (Lewis et al., 1972 and Delpierre and Du Plessis 1974). Most of the species are native to Mediterranean region and tropical parts of the South Africa, particularly the region of the Cape of Good Hope (Raghava, 2000).

The name gladiolus was coined by Pliny the Elder (A.D. 23-79) to describe the shape of the leaf which resembles that of sword (Latin word gladius meaning sword). It is native to South Africa. Most of the species scattered throughout South Africa, Zambesi River, Rhodesia, Mt. Kilimangero, Tanganyika, Natal and Cape of Good Hope, Republic of South Africa, Madagascar and Abyssinia (Ethiopia). Gladioli are said to be cultivated since the days of ancient Greece. As evidenced by a record in Lyte’s Nieeve Herball, it is known since 1578, first introduced in France and soon after spread to England, Germany, Holland and North America. No evidence is available that any species of gladiolus of South African origin was ever grown in Europe prior to 1700. Cornutus described Gladiolus aethiopion bearing light red-scarlet flowers and is from Cape region. In the middle of eighteenth century the South African species were introduced into Europe. Gladiolus tristis closely related to G. grandis was first introduced in Chelsea Physii Garden, UK in 1745 from Cape region and Walat. G. illyricus is native to Mediterranean region. In 1749, Gladiolus grandis was naturalized in Spain from South Africa.

By 1816, France, Holland and Belgium started raising hybrids, the first being Ghant Gladiolus, Gladiolus gandavensis, in 1841, by crossing G. cardinalis and G. psittacinus and vice-versa. Gladiolus primulinus having central petals with hooded characteristics was collected from its native place on the banks of Zambesi River near Victoria Falls in 1902. Victor Lemoine of France used G. primulinus for producing ‘Primulinus Hybrids’ during 1906-1908 while A.E. Kunderd of Indiana, U.S.A. in 1915 produced a similar race ‘Primulinus Grandiflora Hybrids’ by using same parentage as Lemoine. In 1907, first ruffled gladiolus with fimbriated and frilled petals was produced by the efforts of Kunderd.

Gladiolus is a potential flower crop for floriculture industry in India. Gladiolus is commercially grown in West Bengal, Maharashtra, Uttar Pradesh, Uttarakhand, Punjab, Haryana, Sikkim, Jammu and Kashmir, Karnataka, Gujarat, Himachal Pradesh, Tamil Nadu, Madhya Pradesh, Delhi and Rajasthan. The area of the states of U.P., Uttarakhand, Haryana, Punjab, Rajasthan and H.P. and surrounding Delhi grow gladiolus mostly for Delhi flower market (Singh, 2006).

1. OVERVIEW OF AGRICULTURAL SCENARIO AND EXTENSION SYSTEMS IN JAPAN

1.1. Japanese Agricultural Policy and its Short History

The modernization of Japan’s agriculture was started through mechanization such as cultivators, rice planting machines, tractors and combines in the 1960s. Mechanization led to a large decrease in hours spent on rice cultivation, and the redundant labor force moved from agriculture to the manufacturing industry. This movement resulted in the modernization of rice cultivation, high productivity and high income for farm households.

On the other hand, a decreased demand for rice caused by westernization of the diet, e.g. greater consumption of animal products, became a serious problem. The national government decided to regulate rice production, and the acreage of paddy fields equivalent to the excess rice production has been used to cultivate other plants since 1978. Nowadays, the permitted area for planting rice is about 60 per cent of the paddy fields, with the other 40 per cent used to cultivate other plants such as barley, soybean, buckwheat and so on.

Abstract: Genus Jasminum contains 90 species to be true in existence and use, range from landscape to hair adornments, and perfumes. It is native to Indo-Malayan region. Morphological variants from different species have been developed in different regions in India. Unfruitfulness, cross incompatibility, pollen and seed sterility, delicate flower parts, peak and active night flowering, endosperm antagonism often pose significant challenge to breeders. Genetic information and trait heritability is almost unknown for this crop. Phenotypic traits requiring future improvement include recurrent flowering for fresh flower market, high concrete recovery, biotic and abiotic stress tolerance. Future breeding and genetic studies are needed for further transform this crop.

Table cream: It is also called coffee cream, single cream or homogenized cream. It is used in coffee and tests about 20% butter fat.

Table oil expeller: It is a type of the machine that is used for extraction of the oil from the oil seeds (Plate 588).

Table ready meat: Cooked and smoked sausages are called table ready meat.

Tal prolong: This wax is esters of fatty acid glycosides NaCMC.

TAME: It stands for p-Toluene sulfonyl L- arginine methyl ester. It is used in isolation of Trypsin inhibitor.

Beverage: It includes all drinks whether they are fermented or unfermented, prepared from fruits or non-fruit, sweetened or unsweetened eg. tea, coffee, coca cola, cider, maaza are all beverages.

Fruit Beverages : Beverage which is prepared partly or fully from fruit juice or pulps with or without additives eg. pure fruit juice, squash, cordial, RTS beverage etc.

Non-fruit Beverage : Beverage which does not contain any fruit part eg. Coca cola, pepsi, sherbet etc.

Unfermented Juice or Pure Fruit Juice: This is the natural juice pressed out of the fruit and practically its composition remains unaltered during preparation and preservation. No additives like sugar, acid, water etc. are added. eg apple juice, orange juice.

Fruit Juice Beverage: This is the fruit juice that has been considerably altered in composition by adding water, sugar, acid, flavour, colours, preservatives etc. before consumption. It may or may not be diluted before it is served as a drink eg. squashes, nectars, appetizers etc.

Genetic improvement creates permanent, heritable gains in milk production, growth, fertility, disease resistance and environmental adaptation. This chapter explains how artificial intelligence complements conventional phenotypic and pedigree-based selection by analysing large genomic and performance datasets. Machine-learning models reveal genotype-phenotype relationships, predict breeding values and support earlier, more reliable selection. Applications include genomic selection, precision breeding, reproductive technologies, bioinformatics and digital twins. AI can reduce generation intervals and improve the efficiency of breeding programmes, but its success depends on data quality, representative populations and interpretable models. Ethical concerns, genetic diversity and long-term sustainability must also be considered when designing AI-supported breeding systems.

Artificial Intelligence (AI) tools have rapidly transformed the way we work, learn, communicate, and solve problems in the 21st century. From automating routine tasks to assisting in complex decision-making, AI tools are becoming an essential part of modern life and professional environments. These tools use technologies such as machine learning, natural language processing, computer vision, and data analytics to perform tasks that traditionally required human intelligence. As a result, AI is not only increasing productivity but also changing the nature of work across industries. AI tools are software applications or platforms that use artificial intelligence to perform specific functions such as content creation, data analysis, customer support, language translation, image generation, video editing, coding assistance, and workflow automation. Today, AI tools are used in education, healthcare, business, marketing, finance, engineering, journalism, and many other fields. For example, students use AI tools for research, writing, and learning new concepts; businesses use AI for customer service chatbots, data insights, and marketing automation; and designers use AI for image and video creation.

Microbiology is the scientific study of microorganisms, including bacteria, fungi, algae, protozoa and viruses, and their interactions with plants, animals and the environment. Microorganisms are microscopic in size but have enormous importance in agriculture, food production, environmental management and biotechnology. In agricultural systems, microorganisms contribute to decomposition of organic residues, nutrient cycling, soil fertility, plant growth and suppression of harmful organisms. Beneficial microorganisms also form associations with plant roots and improve nutrient availability and plant health. At the same time, certain microorganisms cause plant diseases, food spoilage and environmental contamination. Agricultural microbiology applies the principles of general microbiology to understand these beneficial and harmful activities in farming systems. This chapter introduces the scope and importance of microbiology, major groups of microorganisms, basic laboratory concepts and their applications in agriculture. An understanding of microbial structure, metabolism, diversity and ecological functions provides the foundation for studying soil microbiology, plant–microbe interactions, biotechnology and environmental remediation.

Since the dawn of civilization, the human species had an intimate association with fruits, roots, nuts and other vegetables that sustained them through the ages. This mutualism continued and flourished through domestication and organized culture of horticultural crops. Pretty long before, homestead gardening had been evolved in different parts of the globe independently to become a part of tradition in almost every society. Plant domestication by all likelihoods started around the human settlements. The obvious reasons for this were man’s need, better supply of water and organic household wastes and protection against destruction or grazing by animals, that’s why the prospective horticultural enterprise of homestead gardens all over the world is still the most enduring and sustainable form of family food production system and very important micro-units for conservation of plant genetic resources. The traditional and indigenous endeavour of the tribal people for conservation of land races also noteworthy contribution from one generation to the next. Though cereals are staples for most of the world population, there has been sustained emphasis on horticultural crops, particularly vegetables, all over the world during last few decades. The possible reasons are:

14.1. Introduction

Environmental pollution primarily deals with five types of pollution: soil pollution, water pollution, air pollution, sound pollution and light pollution. However, soil, water and air pollutions are considered very important as the pollutants from the environmental compartments may be cycled within themselves, enter the food web and interfere the biological processes adversely of any living species. Soil supplies nutrients and water to plants which, in turn, act as the nutrient supplier to animals and humans. Thus, maintenance of soil quality is considered prerequisite for growth of plants, animals and humans. If soil, water and air are polluted through various mechanisms, living components in the environment are suffered adversely. Soil, water and air pollutions are associated with the build-up of soil contaminants such as toxic organic and inorganic compounds, petroleum hydrocarbons, radioactive materials, salts, disease causing agents etc. above the permissible limit, so that their presence will cast adverse effects on physicochemical and biological properties of soil which in turn exert negative impact on crop growth and on any non-targeted organisms. Common soil contaminants include heavy metals, pesticides, petroleum hydrocarbons, fertilizers if used in excessive amount, and many others. Contamination of the soil, air and water results from intensification of farming activities. Primarily nutrients (particularly nitrogen and phosphorus), sediment, wastes, pesticides and salts are regarded as agricultural nonpoint source pollutant. Realistically, most of the pollutants originate from anthropogenic activities, although there exists many naturally occurring mineral components that may exhibit toxicity towards living system at higher concentration. Land disposal of municipal and industrial wastes, automobile emissions, mining activity, and application of fertilizers and pesticides to agricultural field cause a continuous accumulation of heavy metals and other pollutant components in soils. These pose threats of environmental degradation via soil erosion, loss of biodiversity, climate change etc.

The major focus of the study was to critically analyse the overall performance of Women Dairy Cooperative Societies (WDCS) in two districts of Odisha. The methodology used in carrying out investigation has been outlined in eight sections as mentioned below.

Biodiversity is a magnificent contribution of nature on our planet. The great variety of life forms on earth has catered for man’s needs over thousands of years. This diversity of living creatures which forms a support system has been used by each civilization for its growth and development. Those that used this “bounty of nature” carefully and sustainably survived. Those that overused or misused it disintegrated. The attempt to classify and categorize the variability existing in nature for over a century has led to an understanding of its organization into communities of plants and animals. This information has helped in utilizing the earth’s biological wealth for the benefit of humanity and has been integral to the process of development. This includes better health care, better crops and the use of these life forms a raw material for industrial growth which has led to a higher standard of living for the developed world. However, this has also produced the modern consumerist society, which has had a negative effect on the diversity of biological resources upon which it is based. The diversity of life on earth is so great that if we use it sustainably we can go on developing new products from biodiversity for many generations. This can only happen if we manage biodiversity as a precious resource and prevent the extinction of species.

The sustainable management of biodiversity is one of the most important challenges facing humanity. Biological diversity, abbreviated to biodiversity, refers to the variety of life forms at all levels of organization, from the molecular to the landscape level. These are the legacy of billions of years of evolution, shaped by natural processes and increasingly, by the activities of humans. Losing biodiversity has eroded the basis for social and ecological resilience, which has resulted in reducing the capacity for adaptive responses in a rapidly changing world. However, human activities still continue to have a large impact on the environment and on biodiversity. Agricultural, urban and infrastructural developments and climate change has exacerbated biodiversity loss. As a result, ecosystem functions and services are affected with serious consequences. The Sustainable Development Goal should be devoted to “protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss”. It is high time to realize the linkages between the severity of global biodiversity loss and degradation of ecosystems and the negative impact that this situation have resulted on food security, nutrition, access to water, health of the rural poor and people worldwide.

INTRODUCTION

India is endowed with a rich and vast diversity of natural resources. However, increasing demographic pressure, unscientific use of soil and water, rapid industrialization and urbanization are leading to over exploitation of the resources. Prime agriculture lands are being diverted for non-agriculture use. The per capita availability of cultivated land has declined over the years from 0.53 ha in 1950 to 0.32 ha in 2001 and is expected to further reduce to 0.23 ha by 2025 and to 0.09 ha by 2050 (GOI 2011). Owing to population pressure the consumption of fuel-wood and fodder in the country is much higher than what can be sustainably removed from forests. In India, nearly 86 million tonnes of fuelwood is being removed from the forests and plantations every year in excess of what they are capable of producing on sustained basis (Planning Commission 2001). Our rich and bountiful biological diversity is also showing signs of erosion which is affecting the livelihoods of millions of people who are directly or indirectly dependent on it. Further, water is mostly treated as a free commodity in the country which is leading to its unsustainable exploitation. Erosion due to wind and water is also leading to depletion of natural resources. About 5334 m tones of soil is lost (16 t ha-1) due to wind and water erosion annually which is highest in black soils (24-112 t ha-1) followed by Shiwaliks (80 t ha-1) and shifting cultivation (27-40 t ha-1) (Mandal et al. 2008). It is now widely accepted that future of food, livelihood and environmental security depends upon the attention paid to conservation, sustainable development and management of natural resources. Corrective measures are immediately required to check the damage caused to the resource base and environment. 
Traditionally, trees and crops were grown in association with each other on farm lands. The reason was to get multiple outputs from same piece of land, though such systems were exclusively meant for sustenance with little or no commercial intent. As the population increased there was a need to produce more food and hence slowly the tree component vanished from the farmlands and monocropping became dominant. Over a period of time, due to monocropping, soil degradation had been observed. The need of the hour is to accept the trees as an integral part of the farming system to revert soil degradation and erosion and also to reduce the dependence of external inputs in form of fertilizers, pesticides etc. in the production system.
Of late, incorporating trees on the farm lands has been given impetus to get multiple products (fodder, fuel, timber, fiber and fruits) on one hand and resource conservation (soil, water and environment) on the other. Different agencies (institutes, universities and NGO’s) are working on developing region specific agroforestry models to derive maximum advantage of production and conservation from every unit of land. Agroforestry is capable of yielding both wood and food besides conserving and rehabilitating ecosystems. Agroforestry generates high income and minimises risks through efficient utilization of available resources and is thus considered   a potential technology for commercial and protective farming.
The extent of the area under agroforestry is not very clear. Trees outside forests in India is estimated between 14,224 million (Ravindranath and Hall 1995) and 24,602 million (Prasad et al. 2000) which is spread over an equivalent area of 17 million ha (GOI 1999) supplying 49% of the 201 million tonnes of fuelwood and 48% of the 64 million m3 of timber consumed annually by the country (Rai and Chakrabarti 2001). Dhyani et al. (2006) reported 7.45 million ha under agroforestry.  As per one of the estimates, about 27.52 million ha is under various types of tree plantations, which include agroforestry, social forestry, farm forestry and others (Table 1). The task force on Greening India (Planning Commission 2001) has identified a potential of 10 millions ha in irrigated lands and another 18 million ha in rainfed areas that could be developed through agroforestry on watershed basis. 
The present chapter focuses on the advantage of integrating trees on the farm lands in form of agroforestry for natural resource management.

Mungbean (Vigna radiata L Wilczek) is considered to be originated from Vigna sublobata. It is also known as green gram, an important short duration grain legume with wide adaptability, low input requirements, and the ability to improve soil fertility by fixing atmospheric nitrogen. Mungbean is well suited to a large number of cropping system and constitutes an important source of cereal based diets. Mungbean is used for different purpose. The major portion is utilized in making dal, curries, soup, sweets and snacks. The food values of mungbean lie in its high and easily digestible protein. Mungbean is grown throughout Asia, Australia, West Indies, South and North America, Tropical and subtropical Africa. However, India alone accounts for 65% of the world acreage and 54% of the world production. It is widely cultivated in India in different seasons; however, the maximum area is under kharif cultivation. Extremely plastic morphology, phenology and short maturity duration (60 days) makes the crop ideal as a catch crop, inter crop or relay cropping. It is grown as sole relay crop in rice fallows during rabi season in A.P., Tamilnadu, Karnataka and Orissa and sole catch crop during spring/summer season in Uttar Pradesh, Bihar, West Bengal, Jharkhand, Punjab, Haryana & Rajasthan (Table 1).

Chickpea, Cicer arietinum L, is the second most important pulse crop in the world. In India, it occupies prime position in terms of area, production and economic value and as an important constituent vegetarian diet. Chickpea is traditionally grown in many parts of the world covering Asia, Africa, Europe and North and South America. But the bulk of it is produced and consumed in South Asia and increasingly in Middle East as well as in some Mediterranean countries. Recently, chickpea cultivation started in Australia, Canada and USA mainly for export to south Asia. The cultivated species, Cicer arietinum L. (2n=16 and n=8), is characterized by possessing two distinct types-small and brown seeded known as desi type, and bold and white seeded known as kabuli type. The former is mostly cultivated in Indian sub-continent. Chickpea (Cicer arietinum L.) is also known by several common names viz., Bengal gram, Gram, Chhola, Hommes and Garbenzobean.

Chickpea provides 2-3 times more protein than many cereals, constituting a major component of the agrarian diet of the Indian sub-continent. Chickpea grains provide about 18-24% protein, 4-10% fat, 52-70.9% carbohydrate, 10-23% fibre, minerals and vitamins. Among essential amino acids lysine, methionine, threonine, valine, isolucine and leucine are major components of seed protein. It also contains considerable amount of vitamins such as B₁ and B₂, ascorbic acid (vitamin C) and niacin also. Chickpea, therefore, plays an important role in human nutrition.

Soil health and nutrient availability are fundamental determinants of plant growth, crop productivity and sustainable agricultural production. This chapter examines how artificial intelligence can support soil health monitoring and nutrient management. It introduces soil health concepts and nutrient dynamics before exploring AI technologies capable of processing soil, environmental and crop-related datasets. AI-based approaches can assist in identifying soil conditions, assessing nutrient requirements and developing site-specific nutrient management strategies. Integration with precision agriculture technologies can improve fertilizer-use efficiency and reduce unnecessary inputs. The chapter also considers practical case studies, challenges and future opportunities. By combining AI with agricultural data, soil monitoring can become more timely, precise and useful for informed crop management.
