Introduction

The concept of Computer Aided Design (CAD) for landscape gardening is comparatively new. It can be defined as design and drafting of a landscape garden with the aid of computer. It can also be defined as use of information technology in garden designing. The core of the CAD system is software, which makes use of graphics for product representation. Computer aided designing is an important industrial art, extensively used in industry and landscape architecture designing and for many more purposes. For landscape designs, it represents a practical solution for the imperative needs of helping to visualise the future. Now-a-days, CAD is used to create 2D or 3D computer models. CAD assists the designer

Introduction

The need of the agricultural community was the force of motivation for the development of broad-spectrum pesticides towards the management of pests and diseases of cultivated crops. Advances in pesticide were measured exclusively by the assessment of its efficacy in management alone. But today food production has ceased to be a major concern, due to stable population levels and success of innovative agricultural technologies. At this juncture, the agrochemical industry that primarily recognized the farmers as their customers has failed to acknowledge the public as an important client. Perception of the public reflects that, the negative aspects of pesticides seem to outnumber their benefits. The increased reflection on environmental concern over pesticide use has been instrumental in a large upsurge of biological disease control. Development of fungicide resistance among the pathogens, ground water and foodstuff pollution and the development of oncogenic risks has further encouraged for the exploitation of antagonistic microflora in disease management

Aim

To design the grassed water ways or open channel

Geometric characteristics of different waterways

The shape of open channel is dependent upon the field conditions and types of the construction equipments used.

The common shapes of open channels generally used are (i) Parabolic or semi circular (ii) Triangular (iii) Rectangular and (iv) Trapezoidal section.

The parabolic shape approximates a natural channel. The reason is that in natural course of channel flow, the trapezoidal and triangular sections tend to become in parabolic shape due to deposition of sediments and bank erosion.

Introduction

As per 20th Livestock Census, 2019 goat population in the country was 148.8 million, the second largest species in terms of number after cattle. Uttar Pradesh, one of India’s largest states in terms of population and agricultural activity, boasts a substantial goat population of 14.48 million, which accounts for approximately 9.73% of the country’s total goat population. Goats indeed play a crucial role in many agrarian economies worldwide, including India. In regions where crop and dairy farming may not be as economically viable, goats provide a valuable source of income and sustenance for small and marginal farmers as well as landless laborers. Goats, specifically Capra hircus, possess unique qualities that make them valuable assets in meeting this growing demand for animal protein (Rout et al. 2018). The livestock market has been experiencing significant growth, with global trade presenting vast opportunities for livestock farmers to increase their income. One notable trend over the past decade has been the increasing preference for animal protein consumption worldwide. This shift in dietary habits has led to a surge in demand for meat products, particularly in developing countries where access to protein-rich foods may be limited. The adaptability, diversity, and versatility of goats make them an invaluable resource for agriculture and livelihoods in both developed and developing nations, contributing to food security and economic sustainability in many regions (Mazhangaraet al. 2019).

17.1 Introduction

In industrialized nations the air is filled with numerous pollutants caused by human activity or industrial processes, such as carbon monoxide (CO), chlorofluorocarbons (CFC), heavy metals (arsenic, chromium, lead, cadmium, mercury, zinc), hydrocarbons, nitrogen oxides, organic chemicals (volatile organic compounds, known as VOCs, and dioxins), sulphur and other particulates. The presence of nitrogen and sulphur oxide in the air generates acid rain that infiltrates and contaminates the soil. The high levels of nitrogen and sulphur oxide in the atmosphere are mainly due to human activities, particularly burning of oil, coal and gas. Only a small portion comes from natural processes such as volcanic action and decay of soil bacteria. Water pollution is caused by numerous factors, including sewage, oil spills, leaking of fertilisers, herbicides and pesticides from land, by-products from manufacturing and extracted or burned fossil fuels.

Harvesting: “Removal of entire plant or economic parts after maturity from the field" is called harvesting. It includes the operation of cutting, picking, plucking or digging or a combination of these for removing the useful part or economic part from the plants / crops. The portion of the stem that is left in the field after harvest is called as stubble. The economic product may be grain, seed, leaf, root or entire plant.

Harvest Index: (H.I): It is the ratio of the economic yield to the total biological yield expressed as percentage.

H.I = Economic yield / Biological yield x 100

Time of Harvesting: If the crop is harvested early, the produce contains high moisture and more immature ill filled and shriveled grains. High moisture leads to pest attack and reduction in germination percentage and impairs the grain quality.

Late harvesting results in shattering of grains, germination even before harvesting during rainy season and breakage during processing.

For maintenance of garden, a person should well acquainted with different types of tools and implements and their uses. A tool and implement is any physical item that can be used to achieve a goal, describe a procedure or process with a specific purpose. Tools that are used in particular fields or activities may have different designations such as instrument, utensil, implement, machine or apparatus. The set of tools needed to achieve a goal is called equipment. The knowledge of constructing, obtaining and using tools is technology. Varieties of implements and tools are required for carrying out the various garden operations like digging, breaking soil, clods, removal of weeds, levelling of ground, mowing lawns, planting of bulbs, layering and grafting, manuring etc. Some of the gardening hand tools are spades, garden forks, pitchfork, hoes, ploughs, shovels, pruners and ice choppers. Many hand tools have been replaced by electronic tools but gardening and landscaping hand tools are still preferred, because they are easier to use and cheaper. Garden tools can be made up of wood, metal or plastics. Landscaping and Gardening is one of the most rewarding and stress-relieving hobbies. The most common garden tool set includes: shovels, rakes, spades, diggers, trowels, etc. Gardening tools can be power or hand driven. There are some garden tools commonly used (Table 1).

Introduction

Advances in pesticide were measured exclusively by the assessment of its efficacy in management alone. But today food production has ceased to be a major concern, due to stable increase in population levels and success of innovative agricultural technologies. At this juncture, the agrochemical industry that primarily recognized the farmers as their customers has failed to acknowledge the public as an important client. Perception of the public reflects that, the negative aspects of pesticides seem to outnumber their benefits. The increased reflection on environmental concern over pesticide use has been instrumental in a large upsurge of biological disease control. Development of fungicide resistance among the pathogens, ground water and foodstuff pollution and the development of oncogenic risks has further encouraged for the exploitation of antagonistic microflora in disease management.

Biological control of plant pathogens can be broadly defined as the reduction of inoculum density or disease producing activities of a pathogen or parasite in its active or dormant state by one or more organisms, accomplished naturally or through manipulation of environment, host or antagonist or by mass introduction of one or more antagonists. The decades of laboratory experiments have led to the explosion in the field of bio-control and introduced more than 50 commercial formulations comprising of fungi and bacteria. To have a successful management of plant diseases and to have a pollution free environment, the biocontrol agents has to be ensured for its availability for commercial use by the end users. To harness the potential of biopesticides by the stakeholders and end users the product has to be registered under Central Insecticide Board authorities concerned of the respective countries.

Aim

• To design the contour bunds

Design parameters

The design of contour bund includes determination of following parameters:

• Choice of bund
• Spacing of bunds
• Size of bund
• Alignment of bund

1. Choice of bund

The choice of bund should be selected weather the contour bund or graded bund depends on the annual rainfall, soil condition and types of outlets used.

Before the discovery of chemical fertilizer in early 20^th century, organic manures and growing of legumes were the ways of replenishing soil fertility. The only other way was leaving land fallow for a few years before its re-cultivation, a practice followed in shifting cultivation (jhuming) (Garbyal, 1999). This was also true for India, where although the ?rst single superphosphate plant was set up in 1906 in Ranipet (Tamil Nadu), the real use of fertilizer started with the manufacture of urea, the ?rst plant for which was set up in 1959 at Sindri (Bihar) (Tandon, 2014). Organic manures could meet crop-nutrient needs in early days because the average grain yield of most cereals was about 1.5–2.0 t ha^–1, while the average yield of pulses was 0.5–0.75 t ha^–1. However, the crop production scenario changed rapidly after the introduction of dwarf, high-yielding varieties of wheat from Mexico, which led to the “Green Revolution” (Swaminathan, 2013). This was followed by the development of semi-dwarf, high-yielding varieties of rice and hybrids of maize, sorghum and pearl millet. These varieties/ hybrids of cereals needed 100–150 kg N ha^–1 in one growing season, and this could be met only by urea or other N fertilizers; organic manures had no chance and their use became almost nil over a period of next 25 years or so. Well-off young farmers cannot even think of making manure heaps or compost pits, the job is too hard and not a clean one. However, what is ignored is the fact, that organic manures not only supply plant nutrients but also build up soil organic matter, which improves soil physical properties, helps in storing moisture and is the elixir of life for the soil biota (Lal, 2014). A large numbers of reports are available on the effect of adding organic manures and crop residues on improving soil physical (Hati et al., 2007; Brar et al., 2015) and chemical and biological properties of soil (Prasad et al., 1999; Prasad and Mishra, 2001;Sharma et al., 2009; Prasad et al. 2014). Thanks for the organic farming (Prasad, 2005), the interest in organic manures and composts has increased in India and it is now a sought after material. However, it has not entered the main stream of crop production.

Black pepper (Piper nigrum) is indigenous to the tropical forests of Western Ghats of South India. The crop is grown in Kerala, Karnataka, Tamil Nadu, Andra Pradesh and Assam.

3.1. Theoretical background of FPOs

Farmers Producer Organization is a people based organization having both the outlook of cooperation and business. In this context the theories of collective action, group formation, social learning cooperation etc are very much pertinent here.

3.1.1 Collective action

Collective action is visible in FPCs. Collective action is defined as action taken mutually by a group of people to augment their status and achieve a common goal. Over the past two decades analytic philosophers have been investigating the nature of collective action in the sense of acting together.

Air is one of the primary things that make life on earth possible. The earth’s atmosphere or air is made up of variety of gases and other particles. The dynamic layer surrounding the earth’s surface containing various mixture of gases, moisture and solid particles (aerosols) is called atmosphere. The atmosphere is generally defined as the gaseous envelop surrounding the earth.

The formation of the earth was believed to be about five billion years ago. In the first 500 million years, a thick atmosphere emerged from the vapour and gases that were expelled from the interior of the earth. Hydrogen (H2 ), water vapour, methane and carbon dioxide were some of the gases believed to be initially formed in the atmosphere due to out gassing from the interior of the earth. About 3.5 billion years ago, the atmosphere consisted of carbon dioxide (CO2 ), Carbon monoxide (CO), water vapour (H2 O), nitrogen (N2 ) and hydrogen present in atmospheric layers like troposphere, stratosphere, mesosphere, thermosphere (Fig. 2.1). The condensation of water vapour into water led to the formation of oceans in which sedimentation occurred and the hydrosphere was created. In the initial and ancient environment, oxygen was not present. Anaerobic is technical word which literally means without air (where air is generally used to mean oxygen and aerobic indicates the presence of oxygen). Evidence of such an anaerobic reducing atmosphere was hidden in early rock formations such as iron and uranium in their reduced states.

1. Introduction

Biochar, produced from pyrolytic decomposition of lignocellulosic biomass, is a solid hard product and a unique green material for soil amendments. Its use has been identified in Amazon fertility as ancient indigenous practice. Through ‘pyrolysis’ (heating without oxygen) process (‘pyro’ which means caused by heat whereas ‘lysis’ means dis-integration), there are three types of yields we get: a solid product (biochar), a gaseous product (syngas/ synthesis gas), and a liquid (bio-oil). The solid item, biochar, is applied for soil amendments. It can be used in agricultural, industrial, and environmental as a functional material. Solid char, a common pyrolytic outcome is charcoal, typically used to designate the solid char product that is ignited for fuel, whereas “biochar” designates the unique solid char purposively used as a soil amendment agent. On the other hand, the gaseous and liquid counterparts of pyrolysis have commercial applications like green energy, feedstock raw materials, and precursors (Fig.1).

Introduction
Animal sector is growing very fast particularly in India as people’s purchasing power is increasing day by day. With increase in income, people’s dietary habit is shifting towards more animal origin products. The use of antibiotics for animal food production is growing very fast and India is the 4th largest country in the world regarding consumption of antibiotics in veterinary and animal husbandry sector. There is urgent need of AMR mitigation strategies to reduce the effect on human and animal health. As per the World Bank AMR can affect the global GDP upto 3.8% by 2050. Most of the countries in the world are very cautious regarding antibiotic residues and rejecting the livestock products which lead to economic loss. Many world agencies/forum such as CodexAMR Guidelines, UN Political Declaration on AMR Guidelines, Global Leaders Group on AMR reiterated judicious use of antibiotics. All-India Network Project on AMR inLivestock and Fisherieswas started in India to reduce the effect of AMR by educational awareness, adoption at field level, surveillance system and diagnosis but it didn’t meet out the desired outcome. Capacity building programmes in the field of AMR by training, reform in curriculum, collaboration from different fields of professionals can mitigate the harmful effect of AMR. According to the Food and Agriculture Organization (FAO), education and training play pivotal roles in translating knowledge into practical implementation, warranting the inclusion of Antimicrobial Use and AMR as integral components in professional education, postgraduate training, and continuing education within the food and agricultural sectors Training Strategies It involve Antimicrobial Stewardship training for healthcare professionals, public awareness campaigns, farmer education, and veterinary training on responsible antimicrobial use. Other critical elements include fostering collaboration through professional networks, building surveillance capacity, utilizing AI-driven tools for better decision-making, and promoting hygiene and infection prevention to reduce infection incidence and the need for antibiotics.
Training for Healthcare Professionals
There is substantial evidence that both healthcare workers and members of the public have knowledge gaps about appropriate use of antibiotics and mechanisms of antibiotic resistance. Surveillance is a prerequisite to estimate the magnitude of the AMR burden and to establish any intervention strategies, such as antimicrobial stewardship. In order to launch successful intervention approaches through cooperative efforts from different stakeholders (e.g., international agencies, human and veterinary medicine sectors, agriculture and animal production industries, and consumers), the existing knowledge gap needs to be addressed first.

The bougainvillea varieties reported from India have been mentioned above. The exact origin of all the varieties are not available. Breeders, sometimes, do not disclose the origin of varieties. An attempt has been made to trace out the mode of origin of different varieties as per available information (Anonymous 1981, Sindhu 2015, Sindhu and Swaroop 2015, Singh 1999, Singh et al., 1999, Nirody 1932, Sharma 1961, 1962, 1963, 1964, 1968, Sharma 1969, Pancho 1963, 1967, Marigowda 1957, Pancho and Elisco 1959, Pancho and Capinpin 1961, Pancho et al., 1961). Information available is not complete in most cases. Following abbreviations have been used – Hybrid Seedling (HS), Bud Sport (BS), Induced Mutant (IM) :

Tuberose (Polianthes tuberosa) commonly called as Rajanigandha produces waxy, white and fragrant flowers on long spikes which are mostly used as cut flowers for making garlands and extracting essential oil. Among the ornamental bulbous plants, it has great economic potential for cut flower trade and essential oil industry. The predominant characteristics of this crop are its lingering, delightful fragrance and excellent keeping quality.

Animal Husbandry is making a significant contribution to the national economy and socio-economic development in the country. In rural India where over 15-20% families are landless and about 80% of the land holders belong to the category of small and marginal farmers, livestock is the main source of livelihood with the policy of the state Animal Husbandry Department to extend free breeding, vaccination and veterinary services, and permit free grazing on community lands, the farmers were encouraged to expand their herd size without any major financial burden. This has probably been the reason for the presence of the worlds largest livestock population in India. India rank first in buffalo population, second in cattle and goat, third in sheep and seventh in poultry (Table-1). Although the population of livestock during last 10 years has been stable around 485 million, the buffalo population during 1997-2003 has increased by 8.91%, while the cattle population has reduced by 6.89%. There has been a significant increase in population of goats during the last five decades, which is attributed to the decrease in the size of land holdings and persistent drought caused by erratic monsoon, forcing many small farmers to shift from large animals to small ruminants.

1.1. INTRODUCTION

The word research derives from the French “recherche”, which means to search closely. Research is a process of investigation. It is an examination of a subject from different points of view. It’s not just a trip to the library to pick up a stack of materials, or picking the first five hits from a computer search. Research is a hunt for the truth. It is getting to know a subject by reading up on it, playing with the ideas, choosing the areas that interest you and following up on them. Research is the way you educate yourself.

Research can be defined as the search for knowledge or any systematic investigation to establish facts. The primary purpose for research is discovering, interpreting, and the development of methods and systems for the advancement of human knowledge on a wide variety of scientific matters of our world and the universe. Research can use the scientific method, but always not necessary.

Scientific research relies on the application of the scientific method, a harnessing of curiosity. This research provides scientific information and theories for the explanation of the nature and the properties of the world around us. It makes practical applications possible. Scientific research can be subdivided into different classifications according to their academic and application disciplines.

Free radicals, such as singlet oxygen (¹_O2), superoxide (O₂ ^.–) and some active derivatives of oxygen, like H₂O₂ are although generated in plant cells during the course of normal metabolic processes, but their production is notably enhanced when the plants are exposed to any kind of stress environment. The reactive oxygen species damage important cellular components, including cell membrane by peroxidation of lipid and de-esterification of fatty acids.

Plants have evolved a wide range of mechanisms to contend with this problem. The antioxidant defence system of a plant comprises of a variety of antioxidant molecules and enzymes which take care of free radicals produced in the cells. These enzymes are popularly termed as the ‘Scavenging Enzymes’ or ‘Antioxidative Enzymes’.

Conversion of oxygen molecules into its reactive form leads to induction of a sort of stress in plants, to which we call as ‘Oxidative Stress’. It is the equilibrium between oxidative stress and antioxidant enzymes, which determines the fate of a plant.

Plants possess scavenging enzyme system to protect them from destructive oxidative reactions. These enzymes are not restricted to the intercellular compartment but are also found in the apoplast to a limited extent. Some of the enzymes are as follows:-
