6.1. INTRODUCTION

Low temperature is one of the major environmental factors that limit the plant growth. Many plants of tropical origin suffer cold damage when exposed to temperature below 20ºC (Graham and Patterson, 1982, Andrews, 1987). Cold temperature in crop plants are compounded by cold snap– a lower than usual drop in temperature that causes the crop to fail. Low temperature in growing season may reduce germination, retard vegetative growth by inducing metabolic imbalances and can delay or prevent productive development. Each plant species has an optimum range of temperature for its normal growth and development. It varies among the genotypes within a species, the specific temperature also depends on the growth stage and development of the particular genotype.

Oilseed crops have been grown all over the world and are considered important crops due to their economic value. Oilseed crops are primarily grown for edible oil. Recently, oilseeds attracted more attention due to an increasing demand for their healthy vegetable oils, livestock feeds, pharmaceuticals, biofuels, and other oleochemical industrial uses. The increased interest resulted in an 82% expansion of oilseed crop cultivation areas and about a 240% increase in total world production over the last 30 years.

Popularly the term management is used to refer to the group of managerial personnel of an enterprise. But the use of the term management in this sense is not correct, because the managerial personnel of an enterprise are usually designated as ‘managers’, ‘executives’ or administrators. Strictly speaking the term management refers to functional concept of management.

The functioning of the Women Dairy Cooperative Societies depends upon the variations in managerial capacity leading to profit and loss of different WDCS. To make an in-depth analysis, the study was undertaken in undivided Cuttack and Dhenkanal district of Odisha covering 22 randomized WDCS with a sample of 110 women respondents.

The analysis of the findings after statistical treatment have been presented objective-wise as follows;

Socio-economic profile of the members of WDCS involved in dairy production activities.

Gap between procedures prescribed and followed in formation and functioning of WDCS.

Identification and analysis of key performance areas in the WDCS.

Determination of management practices and milk production profiles of WDCS members.

Extent of participation of women members in dairy activities.

Entrepreneurial characteristics of members of Women Dairy Cooperative Society.

Impact of WDCS on socio-economic status of the members.

Correlating variables and their interrelationship in predicting smooth functioning of WDCS.

Constraints faced by the WDCS members.

Suggestions of members for improvement in functioning of WDCS

The chapter deals with the Results and discussion of the study, whose purpose is to provide sufficient information so as to arrive at a valid conclusion. Tables and Figures are commonly used in this chapter to support and supplement textual materials. Discussion helps to interpret the Results of the study from a proper perspective and to relate them with other relevant studies.

Introduction

A total of 109 elements have been discovered and incorporated into the periodic table. Many of these elements are found in the earth’s mantle, crust, and soil, though their abundance varies. The chemical makeup of plants is, to some degree, influenced by the composition of the soil. However, since plants are active organisms, they exhibit selectivity in absorbing elements from the soil. Plants accumulate elements at different rates, absorbing some in large quantities, others in smaller amounts, and excluding most altogether. Before proceeding, it is important to familiarise with several key terms frequently used in this chapter.

Nutrient: A nutrient element is essential for an organism to complete its life cycle, and a deficiency in this element leads to specific deficiency symptoms. The negative effects can only be corrected by providing that particular element. Nutrient elements essential for plants may not be necessary for other organisms, and vice versa. Depending on availability, the nutrient levels in a plant can be deficient, sufficient, or toxic. A nutrient is considered deficient when its concentration is so low that it significantly limits growth and causes recognisable deficiency symptoms. If nutrient levels cause reduced growth without visible deficiency symptoms, they are termed insufficient. The nutrient content range in plants that supports optimal yield of crops is considered sufficient. When the concentration of a nutrient becomes high enough to significantly reduce growth, it is considered toxic.

Soil

Soil is a natural body of mineral and organic constituents differentiated into horizons usually unconsolidated, of variable depth which differs among themselves as well as from the underlying parent material in morphology, physical makeup, chemical properties and composition and biological characteristics (Whitney, 1982; Hilgard, 1892; Dokuchaiev, 1900 and Joffe, 1936).

According to Soil Science Society of America (SSSA, 1970) soil is the unconsolidated mineral matter on the surface of the earth that has been subjected to and influenced by genetic and environmental factors of parent material, climate (including moisture and temperature effects), macro and microorganisms and topography, all affecting over a period of time and producing a product, that is “SOIL” that differs from the material from which it is derived in physical, chemical, biological and morphological properties and characteristics. The unconsolidated mineral material on the immediate surface of the earth, that serves as a natural medium for the growth of plants.

Approaches of Soil Study

Pedological Approach : The origin of the soil, its classification and description are examined in Pedology. (From Greek word pedon means soil or earth). It is the study of soil as a natural body and does not focus on the soil’s immediate practical use.

Edaphological Approach: Edaphology (from Greek word edaphos means soil or ground) is the study of soil from the stand point of higher plants. Edaphologists consider the various properties of soil in relation to plant production.

Soil Science : The science dealing with soil as a natural resource on the surface of the earth, including pedology (soil genesis, classification and mapping) and the physical, chemical and biological and fertility properties of soil and these properties in relation to their management for crop production.

The genus Clostridium belongs to the family Clostridiaceae. The genus name was originated from the Greek word ‘klo ster’, which means ‘spindle’ referring to their individual rod shape. Clostridia are gram positive, large, sporulating anaerobic rods (except C. piliforme which is gram negative). At present, there are more than 200 numbers of species under the genus Clostridium. Among them, 15 species can produce potent toxins and are considered as pathogenic for animals and human. The animal pathogenic clostridia can be classified as neurotoxic, histotoxic and enteric.

Important Points to Remember

• The term Biochemistry (biosG = life) was first introduced by a German chemist Carl Neuberg in 1903. Biochemistry may be defined as a science concerned with the chemical nature and chemical behavior of the living matter.
• Major organic molecules present in the living beings are: carbohydrates, proteins (of course, including enzymes), lipids and nucleic acids.
• Carbohydrates are the most abundant organic molecules in nature. They are primarily composed of the elements carbon, hydrogen and oxygen.
• The name carbohydrate literally means ‘hydrates of carbon’. The simplest carbohydrates are the monosaccharides that have the general formula (CH2O)n where n is 3 or more.
• Carbohydrates may be defined as polyhydroxyaldehydes or ketones or compounds which produce them on hydrolysis. The term ‘sugar’ is applied to carbohydrates soluble in water and sweet to taste.

4.1 Composition of Concentrate Mixture
 
The ingredient composition of experimental concentrate mixture is presented in Table 3. Groundnut cake in T1 and T3 were treated with formaldehyde as a tool of protein protection while protected fat at the rate of 10g per liter milk production per animal in T2 and T3 was added in concentrate mixture before feeding every day.

Introduction
 
Soybean (Glycine max L. Merril) is the world’s most important oil yielding legume which contributes 25% of the global edible oil, about two thirds of the world’s protein concentrate feeds for livestock, poultry and fish. India ranks fifth in the area and production in the world after USA, Brazil, Argentina and China. The contribution of India in the world soybean area is 10% but to total world soybean production is only 4% indicating the poor levels of productivity of the crop in India (1.1 t/ha) as compared to other courtiers (World average 2.2 t/ha) which is a major cause of concern.

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. 

Plant diseases are of paramount importance to humans because they damage plants and plant products on which humans depends for food, clothing, furniture, the environment and in many cases the housing. The kinds and amounts of losses caused by plant diseases vary with the plant or plant products, the pathogen, the locality, the environment, the control measures practiced and combination of these factors (Agrios, 2005). Disease is one of the major biotic constraints to reduce crop yield and also deteriorate the quality of product that ultimately reduce the market price.

Hypothesis: A statement about the value of a population parameter developed for the purpose of testing.

Type I and Type II Errors

•    Type I Error: Rejecting the null hypothesis when it should not be rejected.
    •    Therefore accepting the alternative hypothesis (your theory) when you should not.
    •    Probability of a Type I error is called a.
•    Type II Error: Failing to reject the null hypothesis when it should be rejected.
    •    Therefore not accepting the alternative hypothesis (your theory). Opportunity loss.
    •    Probability of a Type I error is called b.
•    Minimizing Type I errors is the main concern of hypothesis testing

1. IMPORTANCE

India is bestowed with a varied agro-climate, which is highly favourable for growing a large number of horticultural crops such as fruits, vegetables, root tubers, ornamentals, aromatic plants, medicinal herbs, spices and plantation crops like coconut, arecanut, cashew and cocoa. It has emerged as an indispensable part of agriculture, offering a wide range of choices to the farmers for crop diversification. It also provides ample opportunities for sustaining large number of agro-industries which generate substantial employment opportunities. India has emerged as the second largest producer of fruits and vegetables; with largest producer of coconut, arecanut, cashew, ginger, turmeric, black pepper and tea, among plantation crops.

The changing scenario encourages private investment, to go for Hi-tech Horticulture with micro-propagation, protected cultivation, drip irrigation, fertigation and integrated nutrient and pest management, besides making use of latest post harvest measures particularly in the case of perishable commodities. As a result, horticulture crop production has moved from rural confines to commercial ventures and has attracted youth since it has proved to be intellectually satisfying and economically rewarding. It is essential to appreciate the contribution of horticulture, landscaping and gardening in the hospitality industry. Aesthetic use of horticulture freshens up the atmosphere, enhances the look of the property and creates a lasting impression on guests. It also has a beneficial effect on the health.

7.1 Introduction

Sustainable agricultural systems must be adopted to increase the food production keeping in view of increase in human population. In tropical countries, insect pests are major challenges to increase food production by causing significant damage in the crop fields and stored grains and their products. Interventions by implementing timely integrated pest management strategies are necessary to reduce the yield losses. Efforts to control insect pests have predominantly relied on the use of broad-spectrum insecticides.  However, indiscriminate and irrational applications of insecticides have created the problems such as insecticide resistance, resurgence, secondary pest outbreak and the presence of residues in food and environment (Ansari et al., 2013). Globally, to reduce the pesticide dependence, various technologies have been developed using different approaches to monitor and maage insect pests which are discussed in this chapter.

A current focus of the research community is to advance our understanding of phytonematode biology in sufficient detail to develop novel management methods. Progress in this aim is held back by a lack of functional genetic tools: forward genetics in the sedentary endoparasites is restricted to the root-knot nematode Meloidogyne hapla, and relies on natural variants as the source of mappable polymorphisms (Olaf Kranse et al, 2021) and reverse genetics is entirely reliant on RNA interference and is limited by the variable penetrance and stability of the effect. Despite these restrictions, meaningful progress recently has been made. There is nevertheless an expectation that the development of functional genetic tools would accelerate progress in understanding the biology of plant-parasitic nematodes, and thereby also indirectly the development of novel control solutions.

The packaging requirements for food products are as varied as the foods themselves, with each category necessitating unique materials and design considerations to ensure product quality, safety, and consumer satisfaction. Packaging serves as the first line of defense against environmental factors like moisture, light, oxygen, and microbial contamination, which can significantly impact food stability and shelf life. The role of packaging extends beyond mere protection; it also contributes to preserving texture, flavor, and nutritional value, making it a crucial factor in the overall success of a food product. Chapter 10 delves into the specialized needs of different food types—such as bread and bakery items, snacks, dairy products, coffee, and carbonated beverages—analyzing the packaging materials, structural designs, and technologies required to maintain product integrity. The food industry faces the complex challenge of balancing protective packaging with considerations for sustainability, consumer convenience, and regulatory compliance. This has led to the evolution of advanced

Introduction

Challenges in agriculture and natural resource management in the past have prompted changes in agricultural education, research, and extension globally. The sustainable development of agriculture in a country largely depends on the effectiveness of its agricultural extension strategies, encompassing approaches, service delivery, methodology, and processes. The desired outcome of agricultural development is farmers’ outcomes, achievable through engagement, learning, and participation in research and extension processes. Agricultural extension played a significant role in the green revolution by providing farming communities with appropriate technologies and optimal cropping practices. This helped countries transition from being food deficit to food exporting (Ratnakar, 2016). Additionally, extension services play a crucial role in expanding knowledge, skills, and attitudes about the management of socio-economic-agricultural practices by understanding the existing techno political ecosystem and exploring a basket of technology alternatives for making informed decisions.
