Theory

Rural Development: The economic betterment of people as well as greater social transformation. The efforts for rural development comprises the direct and indirect involvement of people at the grass root level for development of agriculture/animal husbandry, industry, communication, education, health and allied sectors. 
Democratic Decentralization: To ensure people’s participation in rural development programmes, democratic decentralization has been the core principle of the government since 1957. In the process, people’s participation in all developmental activities has been the unique phenomena to find out the solutions of their problems.
Panchayat Raj: On the principle of democratic decentralization, Panchayat Raj institutions were launched in 1957 as per the recommendations of Balwant Rai Mehta Committee. Under this, the government has derived its authority from the people, and distribute to some extent to the people for decision and action at the local level called Panchayat Raj.

Building upon the foundational statement, this chapter on “Practical Training for Professional Seeding” recognizes that equipping the next generation of agricultural meteorologists requires a multifaceted approach that goes beyond classroom lectures and textbook knowledge (Fig.6.1). It necessitates immersing students in real-world scenarios and providing them with the tangible skills demanded by the evolving agricultural landscape. Let’s delve deeper into the crucial areas of practical training that will be explored in this chapter:
6.1. Hands-on Experience with Meteorological Instrumentation and
Field Data Collection
This section will underscore the importance of direct interaction with weather monitoring equipment. Trainees will gain practical proficiency in:
• Operating and Maintaining Weather Stations: Learning the intricacies of setting up, calibrating, and maintaining various meteorological instruments like thermometers, hygrometers, anemometers, rain gauges, pyranometers, and soil moisture sensors. This will include understanding the principles of operation, potential sources of error, and best practices for ensuring data accuracy.
• Conducting Field Measurements: Moving beyond automated stations, trainees will learn manual data collection techniques for parameters like leaf area index, canopy temperature, radiation interception, and soil physical properties. This hands-on experience will foster a deeper appreciation for the spatial variability of microclimates and the challenges of obtaining representative data.

INTRoDUCTION

In developing countries, cereals and legumes are the principal source of daily energy and protein intake. The major economic loss caused by grain infesting insects in not always the actual material they consume, but also the amount contaminated by them and their excreta which makes food unfit for human consumption. Today million of tones of the food grains are damaged by the ravages of the pests that not only cause quantitative but also qualitative changes in food grains. Stored product insects depress the food value of a product, introduce pathogens, parasites or toxins or make it less palatable. Insect infestation in high in the tropics and may lead 100 per cent damage in severe cases.
 
In order to cope with the requirement of the increasing population and food problem, at present as well as for the decades to come, the world will have to raise agricultural production very substantially, both by increasing the production and by reducing losses on account of post harvest spoilage especially of cereals and legumes which are the primary sources of food for men kind. This is a major problems during agricultural production, food transfer and processing. Million tonnes of grain worth several hundred corers of rupees every years are either damaged or loss for want of knowledge of scientific methods of saving the foodgrains during storage. In India, post-harvest losses caused by the unscientific storage, rodents, insects, micro-organisms, moisture etc. account for about 10 per cent of total foodgrains (Anonymous, 1971). A world survey by F.A.O. indicated about 5 per cent loss of cereals, in storage annually (Herford, 1952).

Introduction

The first step of geostatistical analysis in R is the creation of dataset which is acceptable in R environment by using the data collected from field survey or laboratory experiments. Different type of data is collected during experiments e.g. sand content, silt content, organic carbon content, geographical location of data points, soil type, land use type etc. Here, we will discuss how these data are converted into a acceptable dataset format for R environment and how we manage these data. In R this task is performed in two steps. First, a data structure is created to hold the data and second is the entering or exporting the data into data structure.

9.1 Introduction

Depleting natural resources, regulations on synthetic material, growing environmental awareness and economic considerations today happens to be major driving force for utilization of wastes from the agricultural crops and their residues throughout world [1]. These challenges have led to the introduction of sustainable waste management practices via optimization of processing technologies for minimization and creative conversion of the plant and the processing industries biowastes the world over [2,3,4,5]. Although world prices for sugar and petroleum products have shown spectacular variations during the last few decades, the long term outlook is very likely to be a continuous increase in the price of all fossil fuels and stagnation, at best, for the price of sugar [6]. This gloomy prospect led to the renewed interest in the wastes of the sugarcane industry during the last 50 years and has proved that the optimal use of wastes can provide not only a non-negligible support to the sugarcane industry but will also be able to redress the difficult situation sugar is presently experiencing [7]. Reliable statistics are not available to show the detailed end uses of these wastes on a world basis, but from a very rough picture of their trade, we can say that the wastes from the sugar and jaggery industry serve to be amongst the richest bioresource in this era of recycling of biowastes for renewable wealth generation [8].

Introduction

India has predominantly agrarian economy with just 2.5% of the world’s geographical area, but has about 17% of its population. India’s population has increased from 361 million in 1951 to 1270 million at present: a three and half-fold increase in a span of 63 years. By 2020, India will need about 294 million tonnes food grains (Kumar, 1998). However, only 259.29 m t was produced in 2011–12 (Directorate of Economics and Statistics, Ministry of Agriculture, 2012), implying that about 34 m t additional food grains have to be produced from the same or even lesser land area.

WORLD HISTORY

Work on ornamental crops was first initiated in Krelage Nursery founded by Ernst Heinrich Krelage for bulbs, lilium and dahlias in 1811. During 1895, Taiwan Agricultural Research Institute was established for ornamental crops. The first yellow corn Golden Bnatam was listed in Burpee’s Catalogue in 1902. In 1909 Primadonna F1 hybrid variety of begonia was released by the Benary Seed Company in Germany and in the same year Atlee established seed farms at Floradale in California, Erfurt in Germany Anglia in UK and Kashmir valley in India for annual garden flowers. Luther Burbank did excellent breeding works on ornamental trees, flowers and fruits in 1926.

Chrysanthemum (Dendranthema spp.) belongs to family Compositae (Asteraceae). It was named by Carolus Linnaeus from the Greek prefix “chrys” means golden and “anthemon” means flower. Chrysanthemum morifolium is the modern florists chrysanthemum, which evolved as a result of endless variation and hybridization from C. sinensis, C. indicum and C. ornatum (Bailey, 1963). This group is also distinguished as C. hortorum. The name of C. morifolium Ramat has been changed to Dendranthema grandiflora Tzvelev (Anderson, 1987, Heywood and Humphries, 1977). Chrysanthemums are mainly herbaceous perennial and bear flowers in capitula. Chrysanthemum perennates in nature by means of stolons and is readily propagated through basal stem cuttings. It ranks second next to roses in importance among the cut flower crops in the world.

ORIGIN AND DISTRIBUTION

Chrysanthemum is originated in northern hemisphere (Europe and Asia). However, some workers reported that China is the native place of chrysanthemum (Carter, 1980). Most of the species in the lineage of present day cultivars are from China.

Chrysanthemum was first cultivated in China as a flowering herb and is described in writing as early as 15^th century B.C. As herb, it was believed to have the power of life. In 18^th century, they appeared in Japan as the crest and official seal of the Emperor. Japan also has a national chrysanthemum day, which is called the Festival of Happiness. In the western world, they are introduced in England, Japan, France and U.S. have developed a wide range of colours, shapes and sizes of flowers. Since the chrysanthemum was first introduced in the U.S. during colonial times, its popularity has grown such that mums now reign as undisputed ‘Queen of the Fall Flowers’. The Netherlands is the foremost importer of chrysanthemum cut flowers and is the centers for re-export to other parts of the world. In India, chrysanthemum is successfully grown under protected as well as open conditions in different states.

1. INTRODUCTION

Agricultural Extension in Trinidad and Tobago is searching for a way to effectively use Information Communication Technologies (ICTs) to improve the delivery of services to the farming community. The notion of a demand-driven extension service seems to appeal to the Ministry of Agriculture, and many believe that ICT has the potential to become a primary enabler to improving the extension service.

The country has a population of 1.3 million with one of the highest per capita incomes in Latin American and the Caribbean (US$16,090 in 2007). Oil and gas account for 40 per cent of GDP and 80 per cent of exports. The unemployment rate is 5 per cent, and the labour market is characterized by chronic shortage, high price and low productivity particularly in the agricultural sector (Government of the Republic of Trinidad and Tobago, 2008). One of the government’s objectives is to develop a vibrant agriculture sector to reverse the decline of agriculture. The government’s operational plan 2007-2010 identifies a model for transformation which includes joint ventures with the private sector, investments to develop farms via Government to Government arrangements, and improvements in infrastructure and communication (Republic of Trinidad and Tobago, 2007).

Abstract: Among the annual flowers, marigold is commercially important loose flower crop in India. Marigold types with odourless foliage with orange to light lemon colour are available in world market. Being cross pollinating and seed propagated, progeny can segregate widely for traits due to heterozygosity. Improvements in marigold as cut flowers, larger flowers, more intense flower colour, an expanded flower colour range, more uniform plant habit, earlier flowering, more xanthophylls and extended bloom time are future breeding objectives. The use of intraand interspecific hybridization, heterosis, polyploidy and genetics of traits have been presented with a focus on creating novel transformations for this crop in future.

Introduction

Perishable nature of horticultural produce is a major factor contributing in high post-harvest losses. The metabolic processes such as respiration, transpiration, and ethylene production remain active after the harvesting of produce, which drive ripening and senescence Fig. 1. Thus, an effective post-harvest handling is crucial to delay these changes. The rate of these processes depends on the produce’s physiological characteristics, composition, and storage conditions like temperature and humidity. Low-temperature storage is the simplest and most efficient method to slow down deterioration Escobedo-Avellaneda and Welti-Chanes, 2016. Combining low temperatures with methods that limit oxygen exposure, which fuels many enzymatic reactions, further extends shelf life and maintains food quality. Reduced oxygen levels decrease respiration and the activity of enzymes like polyphenol oxidase and peroxidase.

Genetics is the study of what genes are, how they carry information, how their information is expressed, and how they are replicated and passed to subsequent generations or other organisms.

DNA in cells exists as a double-stranded helix; the two strands are held together by hydrogen bonds between specific nitrogenous base pairs: A-T and C-G.

A gene is a segment of DNA, a sequence of nucleotides, that code for a functional product, usually a protein.

When a gene is expressed, DNA is transcribed to produce RNA; mRNA is then translated into proteins. This is also referred as Central Dogma of Life. The DNA in a cell is replicated before the cell divides, so each daughter cell receives the same genetic information.

Analyzing feeds for nutrient content is essential for proper balancing of livestock rations. This is especially essential for those feeds that have undergone the fermentation process. Silage samples should be analysed for dry matter, protein fractions (degradable and undegradable protein, soluble protein, and heat damaged protein), ADF, NDF, mineral content and energy. In addition to these components, lactic, acetic, and butyric and propionic acids, pH, ammonia nitrogen, ethanol, and yeast and mold counts are also quantified.

1. Introduction

Agriculture and its allied sector is the largest economic sector in India and Indian economy depends heavily on the performance of this sector. Along with production, changes are occurring in supply, machinery, processing, distribution and marketing in the agriculture sector. All over the world, agriculture is passing through a phase of transition, and elements such as discrimination free trade, fair trade, transparency and its resulting predictability, scope for fair competition are being facilitated in to the agriculture sector through different norms and agreements. Due to the concerns about the environment, requirement of clean fuel which can be derived from vegetable sources are also getting increased. All these developments have created new opportunities and scopes for agriculture and agribusiness. Agripreneurship is considered as an employment in the strategy in the country especially for rural people. It promotes our economy by improving productivity and integrating the products into different markets including international markets. It helps in the reduction of cost and avoiding the uncertainties related to markets. To promote micro to medium scale industries, agripreneurship has a major role. Agripreneur faces constraints in related to identification of scope, proper time management and allocating budget etc. and proper project management skills are required to counter these constraints. Agripreneur should also consider sustainability, social and economic factors also (Gupta et al., 2017).

The male-centered business models were considered as the norm till the advent of the present century. But now we have entered an era where there is consensus that women entrepreneurs’ have huge role in the national economic development. Moreover, a significant number of studies show that even though there is a gap between the number of men and women entrepreneurs, the contribution from

women entrepreneurs has been constantly on the rise. This is despite the challenges faced by women entrepreneurs with respect to availability of credit, training, networks and information access and policy constraints. In order to ensure sustainable economic growth, it is necessary to embrace women’s entrepreneurship as it gives new market opportunities and greater development impact. In this chapter, emphasis is given to women entrepreneurship and its contribution to national economy, social empowerment and national integration. Also the challenges and opportunities faced by women in agri-entrepreneurship and changes in the perceptions on women entrepreneurship are discussed.

Pack inspection: It is similar to continuous inspection except that here inspector(s) may make in-process checks during different processing operations under contract but not required to be present all the times in the plant during operation.

Package: The package means a pre packed box, tin, barrel, pouch or can etc in which food article is packed.

Package store: A store that sells bottled or canned alcoholic beverages for consumption off the premises.

Packaging: Packaging is an industrial and marketing technique for containing, protecting, identifying and facilitating the sale and distribution of agricultural, industrial and consumer products. Packaging is defined as an enclosure of products, items or package in a wrapped pouch, bags, box, cup, bottle or any container form to perform one or more of the functions as containment, protection and preservation, communication and utility or performance. Technically, packaging is a system or method by which a product from the manufacturing point to the consumer level reaches in a safe and sound condition at an affordable cost. The primary purpose of the packaging is to protect the food product, to keep it in good condition and to preserve the flavour until it reaches the consumer. It is therefore, very essential that a suitable form of the packaging is chosen for a finished product. Packaging is an art, which determines the buying decision of a consumer. or Wrapping / placement of objects in paper / other packaging materials, keeping in box, etc is known as packaging which has two main functions, to assemble the produce / objects in convenient units for handling and to protect them during transporting, marketing and storage which results in extended shelf life of the produce. "Packaging" play a very important role not only in ensuring safety of the product during transportation, storage and distribution and in conveying information about the pack contents to the consumers, but also ensuring desired sensory characteristics and microbiological soundless till consumed.

13.1 Introduction
Any metal that is shaped into thin, malleable sheets is called sheet metal. The sheets come in a variety of predetermined thicknesses, known as gauges, and are made of materials ranging from titanium to brass. Although sheets can vary in thickness from fractions of a millimeter to several inches, most are typically less than ¼ inch thick. In sheet metal forming, different techniques are used to exert force on a sheet of metal to plastically change it into the required shape and changing its geometry instead of removing any material. Because sheet metal can be bent or stretched into a wide range of intricate shapes, it can be used to create sophisticated structures that are both very strong and use little material. The most economical forming method available today for producing large quantities of parts is sheet metal forming. On the other end of the spectrum, it can be manually operated in metal workshops for small series items or fully automated in factories. It is a flexible, reliable, and superior process that produces precise metal parts with little material waste. Sheet metal forming components are everywhere in our daily lives, from metal cans to protective housing for hardware. Sheet metal process is an extensive cold working procedure that involves shearing, punching/cutting, folding, riveting, splicing, and moulding such as vehicle bodies using metal sheets that are typically less than 6mm in thickness.
13.2 Sheet Metal Characteristics
The characteristics of the sheet metal are as listed below.
i. Because of its ductility, sheet metal may be shaped into a wide variety of shapes without shattering or cracking.
ii. Because it allows the material to be bent, stretched, and stamped throughout the production process, its malleability is essential for manufacturing.
iii. Another crucial element is the thickness of the sheet metal, which can vary from incredibly thin to several centimeters. Typically, a gauge number is used to indicate the thickness of a sheet metal. A lower gauge number denotes a thicker material and a higher gauge number denotes a thinner material. Sheet metal can be used for a wide range of purposes, from heavyduty machinery parts to lightweight electronic enclosures.

Dragon fruit  (Hylocereus undatus (Haw.) Britton and Rose) is a climbing vine cactus species which has received worldwide recognition, first, as an ornamental plant and then as a fruit crop. Its fruit is the most beautiful in the family Cactaceae with a bright red skin studded with green scales and white or red flesh with tiny black seeds.  The flower is so beautiful that it is nicknamed as Noble Woman or Queen of the Night.  The juicy flesh of the fruit is delicious in taste. It is well established as a new crop in Australia, China, Israel, Malaysia, Nicaragua, Taiwan and Vietnam. In Vietnam, it has become a major export crop, which fetches higher prices than even Durian, the King of Fruits in south East Asia.  The main constraint is that the establishment cost is high due to use of trellises for climbing. The cost of establishment will depend on the type of trellises used, and experience in Sri Lanka shows that relatively cheap trellising is sufficient. The other agronomic practices are easy and less expensive; maintenance cost is low and aftercare is minimal due to fewer pest and disease attacks. Further, the biggest advantage of this crop is that once planted, it grows for about 20 years, and one hectare could accommodate about 800 Dragon fruit plants.

Introduction

Labour markets, poverty and inequality in the growth process
 
The theoretical discussion on the changes in the incidence of poverty and inequality in the growth process of agrarian economies from low levels of income has been a major topic in development economics. The impact of growth is delineated through the labour market, and any predictions about the impact on poverty and inequality must be based on some implicit or explicit view of the structure of labour markets and their functioning.

10.1. Introduction

During last few decades dairy animal production has been intensified several folds, along with this reproductive problems have also increased. For efficient dairy animal production, the cow should show regular reproductive activities like cyclic breeding activity, pregnancy at appropriate time, give birth of a live healthy calf and again pregnant after sometimes. If any of these activities are inadequate, then it substantially affects the profitability of the farm. There is an ample scope of improvement of these reproductive setbacks through traditional breeding, feeding and management. However, reproductive problems can be minimized by the use of recently developed reproductive techniques. It not only minimizes reproductive problems, but also improves the reproductive efficiency of the dairy herd and better exploitation of the genetic potential of high merit animals.
