National Agriculture Development Programme/Rashtriya Krishi Vikas Yojana (RKVY)

Economic reforms initiated since 1991 have put the Indian economy on a higher growth trajectory. Annual growth rate in the total Gross Domestic Product (GDP) has accelerated from below 6 per cent during the initial years of reforms to more than 8 per cent in recent years. The Planning Commission in its approach paper to the Eleventh Five-Year-plan has stated that 9 per cent growth rate in GDP would be feasible during the Eleventh Plan period. However, Agriculture that accounted for more than 30 per cent of total GDP at the beginning of reforms failed to maintain its pre-reform growth. On the contrary, it witnessed a sharp deceleration in growth after the mid-1990s. This happened despite the fact that agricultural productivity in most of the states was quite low as it were, and the potential for the growth of agriculture was high. The GDP of agriculture increased annually at more than 3 per cent during the 1980s.

Since the Ninth Five-Year Plan (1996 to 2001-02), India has been targeting a growth rate of more than 4 per cent in agriculture, but the actual achievement has been much below the target. More than 50 per cent of the workforce of the country depends upon agriculture for it’s livelihood and slow growth in Agriculture and allied sectors can lead to acute stress in the economy because a large proportion of population depend on this sector. A major cause behind the slow growth in agriculture is the consistent decrease in investments in the sector by the state governments. While public and private investments are increasing manifold in sectors such as infrastructure, similar investments are not forthcoming in Agriculture and allied sectors, leading to distress in the community of farmers, especially that of the small and marginal segment. Hence, the need for incentivising states that increase their investments in the Agriculture and allied sectors has been felt.

3.1 Introduction

Pear (Pyrus spp.) is one of the important fruit crops that belong to the family Rosaceae. It is one of the important fruits of the temperate and sub-temperate zones. In India, among temperate fruits, pear is next to apple in importance, acreage, production and varietal wealth. It is grown from warm humid sub tropical plains to cold dry temperate regions of India. In the world, pear is cultivated in China, USA, Argentina, Italy, Turkey, Spain, India, South Africa, Japan, Belgium etc. It is grown under a wide variety of climatic regimes ranging from cold dry temperate hilly conditions to warm humid sub-tropical conditions on the plains of northern India. In India pear is widely cultivated in Punjab, Himachal Pradesh, Jammu & Kashmir, Uttar Pradesh, Uttarakhand etc. Pear fruits are generally sweeter and of softer texture than apples and are distinguished by the presence of hard cells in the flesh, the so-called grit, or stone cells. In general, pear fruits are elongate, being narrow at the stem end and broader at the opposite end.

Introduction

Protein metabolism is a complex and multifaceted process that plays a crucial role in the overall health and function of living organisms. At the most fundamental level, protein metabolism involves the synthesis, breakdown, and utilization of proteins, which are essential macromolecules that serve a wide range of structural, functional, and regulatory roles within the body.

The process of protein synthesis, or translation, begins with the transcription of genetic information stored in DNA into messenger RNA (mRNA) molecules. These mRNA molecules then serve as templates for the assembly of specific sequences of amino acids into polypeptide chains, which ultimately fold into the three-dimensional structures of functional proteins. This highly regulated process is essential for the production of the diverse array of proteins required for cellular processes, tissue repair, immune function, and numerous other physiological activities. In contrast, protein degradation, or catabolism, refers to the breakdown of proteins into their constituent amino acids. This process is mediated by various proteolytic enzymes, such as endopeptidases, exopeptidases, and dipeptidases, which cleave the peptide bonds that hold the amino acid residues together Protein degradation serves important functions, such as the recycling of amino acids for energy production or the synthesis of new proteins, the removal of damaged or misfolded proteins, and the regulation of cellular signaling pathways.

1.0 INTRODUCTION

Among tree spices, nutmeg (Myristica fragrans Houtt) belonging to the family Myristicaceae is the most important, providing two spices, i.e. the nutmeg (dried seed) and the mace (dried aril covering the seed). The latter is more important. Nutmeg is cultivated mostly in the tropical areas of Indonesia and West Indies. The world annual production of nutmeg and mace is around 12000 tonnes and 2000 tonnes, respectively (Krishnamoorthy and Rema, 2001). A native of the Moluccas (The Banda Islands of East Indonesia), nutmeg is presently cultivated in several countries such as Grenada, Malaysia, Papua New Guinea, Sri Lanka, Fiji, some Caribbean Islands, Africa and China including India. Of late, Brazil also started its cultivation. The Indonesian nutmeg known as East Indian nutmeg shares 75% and Grenadian known as West Indian nutmeg shares 25% of world market and they are major suppliers in the world. The East Indian nutmeg is highly aromatic which is preferred by the USA. West Indian type is of mild flavour and is preferred in Europe. The major importers are USA, Canada, Japan and European countries. In USA, the oil is generally preferred whereas the Europeans consume it as whole spice.

The organic quality is based on standards, inspection, certification and accreditation. All organic food is produced and handled according to strict rules called ‘Organic Standards’. Organic standards do not define a quality status which can be measured in the final products (e.g. quantity of pesticides residues, heavy metals, etc). They define the way of production (e.g. that no chemical pesticides and fertiliser are used).

Abstract

Never ending additional need of farmers have forced them to grow more cash crop along with crops used for the staple food. The prime crops as per the food habit, social need has to be produced in the respective locality. The micro planning for agricultural and food production has to be planned for different blocks of a district to meet above needs. The production planning has to be simulated first and programmed for trial production. After successful trail, the same has to be replicated in larger area. Mathematical model development approach is one of the solutions to predict the need of the people and plan production depending on the availability of the input materials like natural resources and other inputs. In addition to this food and nutrient security for the people living in those different areas are very important in present context. Global population is growing fast with 1.2% per annum. Feeding these people increases the responsibility of farmers for growing more crops without considering the soil health. Improper crop sequencing has resulted in imbalance in soil nutrient which results in unsustainable production of forth coming crops. 

Abstract

The desert environment is one of the most challenging environments for human habitation. Inhabitants have to deal with climatic factors such as high temperature, sandstorms, flash floods and lack of water due to low rainfall. The people of Saudi Arabian desert had developed various traditional adaptation approaches such as living in tents, wearing head dresses, settling close to source of water, using camel for transportation, irrigation farming and traditional land management (hema). In recent times, modern technologies for air conditioning, transportation and housing have replaced the traditional adaptation methods especially in the cities. The modern technologies have reduced the challenges faced by the traditional society but has thrown up new challenges to sustainability. The new issues include urban flooding, depletion of underground water, high energy demand and consumption and loss of natural habitat to urbanization. This chapter reviews the traditional and the modern adaptation techniques in Saudi Arabia especially in the urban areas. It examines the implication of the changes for urban sustainability and explores different approaches for reducing the negative impacts. The chapter also dwells on the role of geospatial techniques in adapting to the desert environment.

Forage crops are plant species used to feed domestic animals (such as cattle, sheep, goat, pig, and poultry). Both cultivated and wild plants can serve as forage. The domestic animals feed on forages either by grazing or stall feeding (cut fodder eaten in stalls).

Grazing, that is pasturing of animals, is cheaper and allows production of both livestock and dairy produce at a lower cost because no expense is involved in growing, cutting, transporting or feeding. In North and South America, Australia, New Zealand, and in many other temperate countries pastures are widespread and popular because sufficient land is available. While land is cheap and plentiful, labour is scarce and expensive; hence management of natural, and in recent years sown pastures has received much attention.

Until about fifty years ago, the natural grasslands in the Western countries met the minimum needs of the farmers and grassland management was operated at a level comparable to subsistence agriculture of many developing countries. In other words, emphasis was laid on exploitation of natural productivity of the grassland, using a low level of management based on minimum use of inputs like chemical fertilizers. However, it was soon realized that productivity of native grasslands will have to be greatly improved if the high demands for meat and milk were to be adequately met.

In India, however, out of a total cultivable area of about 131.11 million ha less than 2 per cent is utilized for forage crops because feeding the large human population takes the first preference for land use to produce grain and cash crops. It is, therefore, necessary to intensify efforts, particularly in over-populated countries, for a more efficient production of high yielding forage crops to get maximum return out of minimum land.

4.1 Introduction

Peach is temperate and economically important fruit species and is in third position among temperate fruits after apple and pear. The peach, and its smooth skinned mutant, the nectarine, are primarily grown in temperate zones of the world. Peach belongs to the family Rosaceae and is native to China (Lurie and Crisosto 2005). Peach was also called as Persian apple and was probably carried from China to Persia (Iran) and, thus, peach quickly spread from there to Europe (Lurie and Crisosto 2005). In India, it is grown in the mid-hill zone of the Himalayas extending from Jammu & Kashmir to Khasi hills up to an elevation of 2000 m above mean sea level (Meitei et al. 2013). It is one of the most important stone fruits grown in Punjab, Haryana and the adjacent areas of Western Uttar Pradesh, Uttarakhand and Himachal Pradesh. Because of its refreshing, health promoting and delicious qualities, peach fruit is popular all over Northern India. There are many types of peaches. The free-stone types, which have melting yellow or white flesh, are usually consumed fresh and the second one, the cling-stone types with rubbery flesh, are used in processing; the nectarine, which is characterized by non-fuzzy skin, resulted from a mutation, and Peento, a flat peach with a saucer shape, is another variant. It is also a rich source of vitamin A, iron and proteins. Peaches are eaten fresh, canned or dried and are excellent sources of fibre, vitamins and antioxidants The peach kernel oil is utilized in manufacturing of a large number of cosmetics and pharmaceutical products. Nectarines, scientifically known as Prunus persica var. nucipersica, are commonly known as stone fruits which bears fruits similar to peaches but is smooth and lacks hairy fuzzy feature of peaches.

Successful onion cultivation begins with vigorous, disease-free seedlings and their timely establishment in the field. Seed quality, nursery-bed preparation, growing medium, nutrition, irrigation, weed control and protection against pests and diseases determine seedling performance. This chapter explains conventional and modern nursery-management practices, including raised beds, plug trays, protected structures, soilless media, fertigation and climate-controlled production. It also discusses seedling selection, hardening, transplanting age, spacing and field establishment. Mechanized, robotic and precision transplanting systems are examined as solutions to labour shortages and uneven planting. Climate-resilient nurseries, sensors and automation can further improve transplant survival, resource efficiency, uniformity, productivity and sustainability.

Functional Areas

In any business organization, the commonly identified functional areas are production, marketing and finance. In recent years, the personnel and materials that go into the production process, packing process and marketing process have gained importance and given due importance by treating them separately as personnel and materials management.

Organization functional areas are

• Production Management
• Marketing Management
• Financial Management
• Personnel Management
• Materials Management

The above functional areas are not watertight compartments. The decisions/actions taken in one functional area affect the other functional area. The decisions in production and marketing are influenced by the actions on such matters as volume, terms and conditions of loan. The quantity, quality and timely availability of materials also has a bearing on production and marketing decisions. The labour motivation towards work and supervising ability/skill of supervising personnel also affects production and marketing.

Abstract

Biochar is the product of thermal degradation of organic materials in the absence of air (pyrolysis), and is distinguished from charcoal by its use as a soil amendment. Biochar is generally alkaline in pH and may increase soil pH with greater increase observed in sandy and loamy soils than in clayey soils. Biochar addition can increase cation exchange capacity, base saturation, exchangeable bases and organic carbon content as well as decreases in Al saturation in acid soils. Biochar enhances soil productivity by improving the physical, chemical and biological soil conditions. Improvement in soil structure increase soil water retention. A comparative study of soil fertility and leaching losses of nutrients between an Anthrosol and an adjacent unamended Ferralsols revealed that the Anthrasol had significantly higher P, Ca, Mn and Zn availability than the Ferralsol, and an increased biomass of both cowpea and rice by 38–45% without fertilization. More experimentation is needed to substantiate multiple benefits of biochar application in relevant soil-environment-climate-management factors and minimize any possible drawbacks in Indian perspective. Efficient use of biochar in agricultural system is one viable option that can enhance natural rates of carbon sequestration in the soil, reduce farm waste, enhance crop yield with concomitant improvement in soil quality.

Care and Management of Meat-Type Chickens (Broilers)

Broiler Overview

• Broilers are unisex young chickens raised specifically for meat production. They are typically grown to reach a body weight of 2.0 to 2.5 kg within 5 to 6 weeks, consuming 3.0 to 3.5 kg of feed, resulting in a feed conversion ratio of 1.50 to 1.75.

• Broiler meat is flvored for its tenderness, high-quality protein content, low fat and cholesterol levels, superior flavor, and juiciness.

• The broiler production cycle is divided into three phases based on the birds’ physiological and production needs: broiler starter (0-10 days), broiler grower (11-21 days), and broiler finisher (22 days to marketing).

Host -Pathogen Interaction

Most often, plants become diseased when attacked by living (biotic) or affected by non-living (abiotic) pathogens.

In the first case, at least two components viz., host and pathogen must come into contact and interact for plant disease to occur.

Then, for disease to develop, a third factor, a favorable range of environmental conditions, must also occur.

The interaction of the three disease factors was often visualized as a triangle called the “Disease Triangle".

Each side of the triangle represents one of three components.

Antimicrobial Resistance abbreviated as AMR is defined as the process by which microorganisms like bacteria, fungi, viruses, and parasites change over a period and become resistant to a drug to which they were earlier susceptible to. This makes the medicines ineffective for treatment overtime, thus making infections difficult to treat thereby increasing the risk of spread of diseases caused by them and severe illness which may lead to death. This in turn necessitates the need for development of newer antibiotics. However, there has been a sharp decline in the development and manufacture of new antibiotics in the recent years resulting in development of only few antibiotics in the past two decades. The increase in emergence of antibiotic resistance concurrent with decline in development of newer antibiotics poses a serious threat to health of both humans and animals. Every year about 700,000 deaths have been reported to occur due to resistant infections and this rate is likely to increase further with estimated infections due to resistant pathogens expected to reach over 50 million globally by 2050 (O’Neill, 2016). The worrisome trends of increasing antimicrobial resistance across the globe poses a serious threat to both animal and human health as AMR not only increases the morbidity and mortality rates but also increases the economic burden on health care (Zhu et al., 2022). This presents an extremely grave situation as the supply of new antibiotics is inadequate to cope with the increase of AMR pathogens. The unnecessary use of antibiotics globally especially in the livestock sector as growth promoter further helps in selective enrichment of AMR pathogens which further increases health risks. It is well known that resistant pathogenic and commensal bacteria can persist and spread within and between premises despite zero antimicrobial drug use. This may be explained due to maintenance, replication, and further dissemination of resistance genes by horizontal transfer of genes via natural ecosystem and can occur either by conjugation, transformation and transduction; and these mechanisms can rapidly spread AMR genes among microbial community in natural environment and human microbiome, where these resistant bacterial species may be selected due to presence of antimicrobial drugs (Zhu et al., 2022). The physical transfer of bacteria via movement of animals, workers, and equipment and ineffective cleaning and disinfection may also be responsible for increasing the AMR pathogens in the natural environments.

Introduction

According to the body needs, minerals may be divided into 2 groups like macrominerals and microminerals. Macrominerals are required in amounts greater than 100 mg/day. They include 6 elements like calcium, phosphorus, magnesium, sodium, potassium and chloride. Whereas microminerals are also known as trace elements and are required in amounts less than 100 mg/day. They include 10 elements like chromium, cobalt, copper, fluoride, iodine, iron, manganese, molybdenum, selenium, zinc and silicon. Some minerals are always required since small amounts of inorganic salts are always excreted Fruits, vegetables and cereals are the chief sources of the mineral elements in the diet. Milk products supply the majority of the calcium and phosphorus in the diet.

Milk and milk products are the richest source of calcium along with beans, leafy vegetables and egg yolk. It is absorbed from upper small intestine. Absorption of calcium is active process and requires calcium binding protein present in the intestinal mucosal cells. The absorption is regulated by vitamin D, parathyroid hormone, high protein diet, pH, high dietary lactate and citrate are the factors that promotes calcium absorption. Whereas high dietary phosphate, alkalinity and impaired fat absorption are the factors that inhibits calcium absorption. Of the total body calcium, 99 % present in bones and teeth in the form of hydroxyapatite and 1 % is present in body fluids and other tissues. Calcium in bones acts as a reservoir, which helps to stabilize calcium ions in plasma and extracellular f luid Parathyroid hormone and active vitamin D stimulate osteoblasts while estrogen hormone inhibits osteoclasts.

Introduction India’s animal husbandry sector plays a vital role in the country’s economy and food security. It provides livelihood to millions of people, contributes significantly to the agricultural gross domestic product (GDP), and meets the nutritional needs of the population. The sector encompasses various aspects of livestock production, including dairy farming, poultry farming, sheep rearing, goat rearing, and piggery. Milk Production India is the world’s largest milk producer, with an annual production of 230.58 million tonnes in 2022-23. This represents an impressive growth rate of 3.83% over the previous year. The top five milk-producing states are Uttar Pradesh, Rajasthan, Madhya Pradesh, Gujarat, and Andhra Pradesh. Egg Production India is also the third-largest egg producer in the world, with an annual production of 138.38 billion eggs in 2022-23. Egg production has grown by 6.77% in the last year. The top five egg-producing states are Andhra Pradesh, Tamil Nadu, Telangana, West Bengal, and Karnataka. Meat Production India’s meat production in 2022-23 was 9.77 million tonnes, with an annual growth rate of 5.13%. The top five meat-producing states are Maharashtra, Uttar Pradesh, West Bengal,

Introduction

In the process of creating a hole in the metal surface through a drill, we use a drilling machine. We use a tapper shank and parallel shank to tie the drill to the drill machine. We can also use a drilling machine to do extra experiments i.e., tapping rimming counter shrinking and counterboring. In simple language, we also say that a, it is a machine which is wildly used over world for making a circular hole in various metal workpiece for making desired design or structure.

Enzymes, toxins, growth regulators, and polysaccharides are much more common and perhaps more important in the development of plant diseases. The pathogen produce these substances when grown on certain substrates (inducible). Let’s talk carefully one by one

Enzymes in plant diseases.

Toxins in plant diseases.

Growth regulator in plant diseases.

Polysaccharides in plant diseases.
