Introduction

Groundnut (Arachis hypogaea L.) is an important traditional oilseed crop of India contributing to 3.9 million tons of global vegetable oil ranking the sixth in the sequence of oilseed crops. Added to its importance as an oilseed, groundnut is also an important food legume cultivated in an area of about 22 million hectares worldwide leading to a production of 38.6 million tons as per the FAO statistics of 2011 (ICRISAT, 2017). China and India are the leading groundnut producers followed by USA and Nigeria. Africa with 12.40 m ha area and 11.54 m tons of production, and Asia with 11.87 m ha and 29.95 m tons, together account for 95% global groundnut area and 91% of global groundnut production. There was a substantial increase in global groundnut production by about 5 m tons in 2013, from 40 m tons in 2012. In the last decade, 2004–2013, global groundnut production increased by 24%, contributed by 7% increase in groundnut area, and 16% increase in yield. The projected global demand for groundnut and its related products is expected to increase and so there is a need to further increase production and productivity to meet the demand.

Among the different oilseed crops grown in India, groundnut is the major crops grown in kharif / monsoon season. Among different states if India, Gujarat is the prominent state growing groundnut.

Groundnut has a long history of cultivation since the plant was domesticated and cultivated by the indigenous tribes such as Incas of Peru in South America for more than 1500 years. It is believed that the cultivated groundnut was introduced into India by the Spanish colonizers (Krapovickas, 1968). Groundnut is believed to have been introduced into the USA by the African slaves. Groundnut crop has found an ecological niche in the tropical and warm temperate zones of world, due its impressive adaptability.

1. Introduction

The intricate relationship between agriculture and women has been widely featured in the development discourse for long. Globally, more than 400 million women are engaged in farm work directly or indirectly. In other words, 42 per cent of economically active women are engaged in agriculture and they comprise about 43 per cent of the total workforce in agriculture (Dash and Srinath, 2013). In India, agriculture and allied sectors continue to be the most immediate avenues of employment and income for about 160 million rural women who work as farmers, co-farmers, farm labourers and farm entrepreneurs (Oxfam 2017; Sadangi et al., 2009). It is estimated that about 65 per cent of rural women workers are engaged in agriculture as cultivators and agricultural labourers in the country as opposed to 49.8 per cent of male workers. In these capacities, women perform multiple tasks such as land preparation, sowing, transplantation, harvesting and rearing of animals. Most of these operations are labour intensive and not mechanized (Pachauri, 2019). Besides, they are engaged in off-farm domestic activities such as cooking, cleaning, childcare, water and fuel collection and community activities. Shrinking remunerative opportunities in the farming sector has triggered migration of rural male folk to urban areas and also there is a shift in their job priorities to pursue employment in the rural non-farm sector in recent years. Since women did not feature predominantly in either of these trends, most of them are still engaged in agriculture, mostly as labourers and cultivators (Mehrotra, 2020). Vindicated by the fact that the number of female agricultural labourers in India increased by 24 per cent between 2001 and 2011, even though 7.7 million farmers left farming during the corresponding period. During the period when up to 34 per cent of men in rural areas migrated in search of employment and better economic opportunities, the corresponding figure for rural women is merely 3.6 per cent. A recent study of National Sample Survey Office (NSSO) found that 55 per cent of employed women in India

Nanoscience and nanotechnologies are set to transform the global industrial landscape, but the debate on how to regulate environmental, health and safety risks is lagging behind technological innovation. Current regulatory efforts are primarily focused on the national and regional level, while the international dimensions of nanotechnology governance are still poorly understood and rarely feature on the international agenda. With the ongoing globalization of nanosciences and the rapid expansion of international trade in nanomaterials, however, demand for international coordination and harmonization of regulatory approaches is set to increase. However, uncertainty about nanotechnology risk poses a profound dilemma for regulators and policy-makers. Uncertainty both creates demand for and stands in the way of greater international cooperation and harmonization of regulatory approaches. Falkner Robert and Jaspers Nico (2012) reviewed the emerging debate on nanotechnology risk and regulatory approaches, investigates the current state of international cooperation and outlines the critical contribution that a global governance approach can make to the safe development of nanotechnologies.

Fruit cracking is a serious problem of pomegranate (Punica granatum L.) particularly in arid climate. Cracked fruits are sweet but unfit for long distance transportation. Incidence of cracked fruits varies from 10 to 70 % depending upon the prevailing environmental conditions. Longitudinal or radial splitting of rind surface occurs.

Abstract

Rural indebtedness is an old problem in India. In the 19^th century commercial banking was absent in rural areas and farmer were entirely in the hand of usurious moneylender. Since the British rule, the central government has been trying to extend institutional lending to the rural agriculture sector. To provide credit to the agricultural sector, a multi-agency approach involving co-operative banks, scheduled commercial banks, and RRBS has been used in India. Adequate and timely loan availability at reasonable rates is the basis for agricultural finance policy. The institutional structure for agricultural lending has improved over time in terms of scope and reach. India’s higher education institutions have been focusing their efforts on advancing agricultural finance.

Abstract

Drug design is a complex computational process that involves studying the structural and physicochemical properties of biological moieties in order to identify new chemical or biochemical substances that can be used as drugs with specific pharmacological properties. The drug discovery pipeline is a crucial aspect of drug design that requires a detailed understanding of the various phases involved. In this chapter, we discuss the fundamental principles and phases of drug design. Additionally, we delve into the concept of docking, a critical step in the drug discovery process that involves predicting the orientation and affinity of a ligand binding to a protein target. The use of computational tools and techniques in drug design has revolutionized the field and is essential for the development of safe and effective drugs.

Women have contributed significantly and selflessly since ancient times to uplifting and bettering any nation. A literate woman builds a country; truth cannot be closer than that. Women have always carried the burden of being a wife, mothers, sisters and daughters, all on their own magnificently. They are leaders, decision-makers, entrepreneurs and service providers in different fields. The valuable contributions of women are significant to the well-being of families and communities and the economic growth of any society. Rural women have tremendous potential for developing culture, and their leadership, participation, and education will help eradicate poverty and hunger.

Pomegranate (Punica granatum Linn.) is an important fruit crop cultivated in arid and semi-arid regions, serving nutritional, medicinal and aesthetic need of human beings. It is grown in Iran, Spain, India, Moracco, Egypt, Afghanistan, Arabia, West Pakistan, Bangladesh, Burma, China, USA and Japan.World pomegranate production is currently estimated at 1.5-2.0 million tonnes, 90% of which is in Iran and India. The rest is distributed amongst various Mediterranean countries, China, the United States, Armenia, Azerbaijan, Pakistan, and Argentina (CBI, 2014). In India, it is found from Kashmir to Kanyakumari cultivated in Maharashtra,Gujarat, Uttar Pradesh, Tamil Nadu,Karnataka andAndhra Pradesh.Among the different states growing pomegranate, Maharashtra is the largest producer occupying 2/3^rd of the cultivated area in India followed by Karnataka, Andhra Pradesh, Gujarat and Rajasthan.

Introduction Potato, scientifically known as Solanum tuberosum, is a starchy tuberous crop that belongs to the nightshade family, Solanaceae. It is one of the most widely consumed and important food crops worldwide. Potatoes are native to the Andes region of South America and have been cultivated for thousands of years. They have since become a staple food in many countries and have significant cultural and economic importance. Potatoes are known for their versatility, as they can be prepared and cooked in various ways. They are typically harvested from underground stems called tubers, which come in a variety of shapes, sizes, and colours. The most common varieties have brown or yellowish skin and white, yellow, or creamy flesh. However, there are also red, purple, and even blueskinned potatoes available. The cultivation of potatoes is widespread, with major potato-producing countries including China, India, Russia, the United States, and Germany. Potatoes are adaptable to different climates and can be grown in diverse environments. They are an important crop for food security and economic stability in many regions. Beyond their culinary significance, potatoes have also contributed to scientific advancements.

Real benefits are obtained when we use a participatory approach to curriculum development and reorientation. Primarily, the course contents we provide and the learning will become more effective. If students participate actively in the learning process, then they are more likely to learn and teaching is more likely to be effective. They will have more ownership in the teaching, because their needs will have been identified and hopefully they will also be involved in deciding how their needs can be met. This will increase their motivation, which will help them to learn more effectively.

Introduction

Seaweed, a diverse group of marine algae, thrives in a variety of aquatic environments across the world’s oceans. Found in both shallow coastal waters and deeper offshore regions, seaweed plays a crucial ecological role in marine ecosystems. It attaches itself to rocky substrates, sandy seabed, or even other marine organisms, utilizing the rich nutrients present in seawater for growth. Seaweed populations are influenced by factors such as water temperature, light availability, and nutrient levels.

Chemistry of Creaming

After being drawn from animals, normal milk will form a cream layer on standing. Because of the difference in density between fat globules (920 kg m−3 at room temperature) and milk plasma (density 1030 kg m−3), the granules tend to rise. This causes creaming, which we often want to prevent and it enables milk to be separated into cream and skim milk. Creaming is much enhanced when the globules have been aggregated into flocculates, clusters, or granules.

Cream Ripening

This unit operation serves as an intensive preparation of the cream for the churning process. It is divided into two categories.

1. Physical ripening;

2. biochemical ripening The following criteria are influenced by the cream ripening:

• Consistency, firmness, and spreadability of butter.

• Basic water content of butter during the manufacturing process (bound water in butter, which cannot be removed by any mechanical treatment).

• Buttermilk fat content, which has to be minimized.

The melting and solidification behavior of fat depends on the attached fatty acid, which indicate the hardness of the butterfat.

Natural hardness is caused mainly by seasonal feeding of the milk animals. Winter feed with a great deal of dry feed or roughage yields a hard butterfat with a high percentage of saturated and short-chain fatty acids and few double bonds in the fat molecules.

Summer feeding (green grass) results in fat with longer chains and a higher percentage of unsaturated fatty acids with many double bonds. We therefore distinguish between summer fat and winter fat or summer cream and winter cream.

Introduction

According to Frankel (1957), plant introduction is the transposition of a genetic entity from an environment to which it is attuned to one in which it is untried. According to Bennett (1965), the introduction of wild plants into cultivation and the successful transfer of cultivars, with their genotypes unaltered, to new environments is called as ‘primary’ plant introduction and the rest as ‘secondary’ introduction. However, both are equally meaningful for effective use of plant germplasm.

Types of Plant Introduction

1. Primary Introduction

2. Secondary Introduction

1. Primary Introduction

When the introduced crop or variety is well suited to the new environment, it is directly grown or cultivated without any alteration in the original genotype. This is known as primary introduction. E.g. IR. 8, IR 20, IR 34, IR 50 rice varieties; oil palm varieties introduced from Malaysia and Mashuri rice from Malaysia.

Introduction

A wide range of agricultural pesticides is currently being used in India. In the financial year of 2015, the size of the crop protection market in India was of about $4.5 billion (FICCI, 2016). A large number of these pesticides are also being used in considerable quantity on horticultural crops, including fruit crops. In general, judicious application of a pesticide following Good Agricultural Practices (GAP) does not leave its residues in crop produces above unacceptable limit. But the GAP recommendations are not available for all crop-pesticide combinations. The usage pattern of pesticides also sometimes gets modified at farm level due to sudden climate changes, and under such situations, the indiscriminate use of pesticides to combat disease and insect complex might result in the contamination of pesticides in fruits.

Intellectual property (IP) refers to creations of the human mind, such as inventions, literary and artistic works, symbols, names, images, and designs, which are protected by law. The protection of intellectual property is essential for promoting innovation, creativity, and economic growth. In order to ensure effective protection of intellectual property rights, various governing bodies, organizations, agreements, and treaties have been established at national and international levels. These bodies are responsible for setting and enforcing standards and regulations related to IP, as well as facilitating cooperation and coordination among different countries and stakeholders. Some of the major international organizations and agreements that deal with intellectual property include the World Intellectual Property Organization (WIPO), The Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the Paris Convention for the Protection of Industrial Property. These organizations and agreements play a crucial role in creating a conducive environment for innovation, investment, and development, while at the same time ensuring fair and equitable access to intellectual property for all.
