The goods and services with the help of which the process of production is carried out, are called factors of production. Economists talk about four main factors of production: land, labour, capital and entrepreneurship (or organization). They are also called as the inputs of production. On the other hand, the goods produced with the help of these inputs, are called as the output.
1. Land
Land refers to all natural resources such as forests, water, climate, and soil. It provides space for livestock farms and raw materials for the dairy and meat industries.
Features of Land
1. Gift of Nature – Land and climatic conditions are naturally available. For example, the fertile plains of Punjab and Haryana are naturally suited for growing fodder crops like berseem and maize, which are essential for dairy farming. Similarly, the lush green pastures of Uttarakhand, Jammu & Kashmir and Himachal Pradesh provide an ideal environment for rearing sheep and goats.
2. Limited in Supply – Land is fixed, and certain resources like water bodies and fodder resources may deplete over time. Water scarcity in regions like Maharashtra has forced farmers to shift from water-intensive crops to drought-resistant fodder crops.

Factories are the backbone of industrial growth for economic prosperity of any nation especially for developing countries like India. There is usually huge area available in the factories but the whole area is not covered under construction or used. The vacant spaces of the factory premises are ideal for development of gardens. Moreover, plantation of trees and development of greeneries are now compulsory in industrial areas as per laws for the purpose of environmental amelioration.

Purpose

Gardens at the factories and other industrial places are different from the normal ornamental gardens. These gardens are generally less intensive in nature. The main function isto fulfill dual purpose i.e., beautification and minimizing environmental pollution. Selection of plants should be evergreen trees, free flowering perennials tolerant to air pollution.

Scope

There are large open spaces available within the campus of factories. These are generally located along the boundary wall, inner open areas and other unutilized spaces. As a whole, there is ample scope for development of gardens and other kind of plantation.

Abstract

The Adam bridge, the curvilinear chains of islands linking India (Thanushkodi) with Sri Lanka (Thalaimannar), has been a matter of scientific and mythological debate. While the great epic Ramayana says that Lord Rama built this Adam bridge around 1.5 million years ago to bring back his wife Seetha from Srilanka who was a captive by king Ravana of Srilanka, some reports gave another view that it is coral islands of 1.7 million years of age. Under this backdrop, the author refutes the claim made by NASA that the Adam bridge was located firstly by one of its satellites and cited evidences that the Indian scientists located and mapped it using the IRS satellite data much earlier. Further, on the basis of bundles of beach ridges dated in Tiruthuraipoondi-Vedaranniyam area and as well as some of these continue up to Uchipulli area in Ramanathpuram district, the author assigned an age of 3500 YBP ( Years Before Present) to Uchipulli beach ridges seen in the main land to the west of Rameshwaram and Adam’s bridge and inferred that the Adam’s bridge must be equal to or younger than 3500 YBP. The easterly nosing of Indian mainland in Ramanathapuram – Rameshwaram – Thanushkodi and its further extension in the form of Adam bridge, the author demonstrated that the because of anticlockwisely rotating littoral currents to the north and clockwisely moving littoral currents to the south of Adam bridge, the chains sandy islands namely Adam’s bridge was formed by the segregation of sands in between currents shadow zone after 3500 YBP.

Studies and Findings

There was some coverage in the newspapers some time ago about the discovery of a land bridge (Adam’s Bridge) between Dhanushkodi (India) and Talaimannar (Sri Lanka) by NASA through one of its satellite mission. It was also written in some articles that this land bridge was constructed by Lord Rama 1.7 million years ago to reach Sri Lanka with the aim to bring back his wife Sita from the clutches of Ravana. However, this linkage was refuted by NASA. It accepted that the picture was captured by one of its satellites, but it was unaware of the linkage of the land bridge with the great Indian epic Ramayana. Some reports gave another view and mentioned that the bridge was nothing, but 1.7 million years old coral reefs. Many historians have also come out against linking the Adam’s Bridge with Ramayana.

In the contemporary academic sphere, the demands placed upon faculty members have grown increasingly complex, requiring a multifaceted skill set that goes beyond subject matter expertise. A truly effective faculty body is characterized by several key attributes and supported by institutional mechanisms that foster growth and accountability.
7.1. Effective Mentorship
• The Indispensable Nature of Communication Skills: Exceptional communication skills form the bedrock of effective teaching and mentorship. Faculty must possess the ability to articulate complex ideas with clarity and precision, adapting their communication style to suit diverse learning needs and preferences. This includes not only lucid lecturing but also active listening, providing constructive feedback, facilitating engaging discussions, and utilizing various communication technologies effectively (Fig.7.1). Strong communication fosters a positive and inclusive learning environment, enabling students to grasp concepts more readily, ask pertinent questions, and feel comfortable expressing their thoughts and challenges. Moreover, effective communication extends to interactions with colleagues, administrative staff, and parents, ensuring a cohesive and collaborative educational ecosystem.
• Unwavering Commitment to Student Welfare: Faculty commitment to student welfare transcends the traditional boundaries of academic instruction. It encompasses a genuine interest in the holistic development of students, encompassing their academic progress, personal growth,

At times a pesticide application fails to reduce the levels of a pest. Usually, the farmer blames either the pesticide for this or he thinks that the pests have developed resistance. Though, the usual causes of poor results with an application of a genuine pesticide from a reputable source are:

Abstract

The rhizosphere or the zone of influence around roots harbors a multitude of microorganisms that are affected by both abiotic and biotic stresses. Among these are the dominant rhizobacteria that prefer living in close vicinity to the root or on its surface and play a crucial role in soil health and plant growth. Both free-living and symbiotic bacteria are involved in such specific ecological niches and help in plant matter degradation, nutrient mobilization and biocontrol of plant disease. While the rhizosphere as a domain of fierce microbial activity has been studied for over a century, the availability of modern tools in microbial ecology has now permitted the study of microbial communities associated with plant growth and development, in situ localization of important forms, as well as the monitoring of introduced bacteria as they spread in the soil and root environment. Plant-microbe researchers have studied the diversity of rhizobacteria in a variety of plants, cereals, legumes and others along with assessment of their functionality based on the release of enzymes (soil dehydrogenase, phosphatase, nitrogenase, etc.), metabolites (siderophores, antifungals, HCN, etc.), growth promoters (IAA,

Introduction
India possesses the largest livestock population globally. To sustain this extensive livestock sector, it is essential for the country to ensure a corresponding supply of feed and fodder that meets the growing demand. However, a significant barrier for enhancing livestock production in India is the inadequate availability of feeds and fodders, both in terms of quality and quantity. The limited land designated for cultivation approximately 3.3-4.4% of the total cultivable area coupled with the decline in pasture lands and a shift in cropping patterns from coarse cereals to commercial crops, poses substantial risks to fulfilling the nation’s feed and fodder requirements. A considerable portion of the coarse cereal byproducts is utilized as fodder. Projections indicate a shortfall of 28% to 35% in green fodder, 10% to 11% in dry fodder and 33% to 35% in concentrates (Niti Aayog, 2018). The current status of feed and fodder resources is insufficient to meet the rising demand. Proper feeding is vital for the improvement of livestock breeds, as inadequately fed improved breeds tend to deteriorate more quickly. Consequently, there is a persistent imbalance between the number of animals and the available feed resources.

An unmanned aerial vehicle (UAV) is any aircraft or flying machine that operates without a human pilot. UAVs can be controlled autonomously or remotely by a human operator using onboard computers and robotic systems. In surveillance or military operations, UAVs are often part of an unmanned aircraft system (UAS). Drones, a common term for UAVs, have gained popularity for various applications such as photography, videography, surveying, inspection, and delivery.

The essential components of a drone include the frame, motors, propellers, battery, flight controller, and sensors. Let’s explore these components in detail:

1. Frame

2. Battery

3. Flight Controllers

Livestock feeds are generally classified according to the amount of a specific nutrient they furnish in the ration. They are divided into two general classes roughages and concentrates. Roughages are bulky feeds containing relatively large amount of less digestible material, i.e. crude fiber more than 18% and lower than 60% TDN on dry matter basis. Concentrates are feeds which contain relatively smaller amount (less than 18%) of fiber and have comparatively high digestibility and as a result higher nutritive value having more than 60% TDN.

A. Roughages

Roughages are subdivided into two major groups – succulent and dry, based upon the moisture content. Succulent feeds usually contain moisture content from 60 to 90%, whereas dry contains only 10 to 15% moisture. Succulent may again be divided into pasture, cultivated fodder crops, tree leaves, silage and root crops. Dry roughages may be further classified as hay and straw based on the nutritive value and methods of preservation.

Introduction

Agriculture has been the joint venture of both men and women since the time immemorial. Women play a significant role in agriculture and are responsible for half of the world’s food production in most of the developing countries. According to International Food Policy Research Institute (IFPRI), women play a central role as producer of food, managers of natural resources, income earners and care takers of household food and nutrition security. Food and Agriculture Organization (FAO) studies also confirm that women are the mainstay of small scale agriculture, the farm labour force and day to day family subsistence. About 70 per cent of agricultural workers, 80 per cent of food producers and 10 per cent of those who process basic foodstuffs are women and thus making up more than two-third of the workforce in agriculture production. They currently account for 60-70 % of all food production in all the developing countries. Other than agriculture and allied sectors like dairy, poultry, fishery, goatery and sericulture, women are also skilled in handicrafts, wooden works and various other types of small enterprises which boost the rural economy. They are also involved in small scale enterprises like rope making, broom making, bamboo works. All women in rural areas, irrespective to their age, size of their family, size of land holding, caste and community, perform major agricultural tasks. The rural women form the most important productive work force in the economy of majority of the developing nations like India. Agriculture sector employs 4/5^th of all economically active women in the country and 48 per cent of India’s self employed farmers are women (Kumar, 2013). In present scenario, nearly 84 per cent of economically active women in India are engaged in agriculture and allied activities. In a study undertaken by DRWA (Directorate of Research on Women in Agriculture) in low land and rainfed rice in Odisha revealed that under low lying situation, women spent nearly 20 days in uprooting and transplanting, 10 days in intercultural operations and 20 days in harvesting and transportation. In up land rainfed rice women were involved for 40 days mainly in gap filling, weeding, harvesting threshing etc. (Arya, 2008). The rural women of low-income category and lower caste perform more work in farm related field activities while the women of higher income groups perform more work in post harvest processing like storing of food grains, parboiling, winnowing, preparing puffed rice etc. In tribal areas, women participate in all agricultural operations except ploughing. They are seen to do more hard work in the fields than men. Depending upon the socio-cultural variations among different tribal communities, Non Timber Forest Products (NTFPs) are collected by tribal women. They collect food, fodder, fuel, medicinal plants, building materials and other household materials. Every day during off seasons, they go to forest for collecting NTFPs and sell it in the local hats (market) for day to day expenditure of their family. Sal and kendu leaves are also collected by them for their livelihood support. Ladies are the decision makers in farming sector as well as on other domestic affairs because of their greater contribution of household income. Marketing of their produce and also other materials collected from forest by them are exclusively done by the women group. Tribes mostly depend on forest and forest products during the dry period of the year. Now-a-days non-availability of NTFPs has shifted women from self employed to wage employment.

World-wide, both in developing and in developed countries;family farming is one of the most predominant forms of agriculture. It includes a wide spectrum of farm sizes and types. In high-income economies, it ranges from very large land holdings that are easily cultivated by one or two family members with the use of labour-saving machinery and hired labour. In low-income economies,with small holdings of a few hectares or less and that are often oriented towards subsistence with low marketable surplus.

Glyoxysomes appear in the first few days after seed germination in endosperm cells and associate closely with lipid bodies. They disappear after the storage fats are broken down and converted into carbohydrate.

Animal husbandry is an integral component of Indian agriculture supporting livelihood of more than two-third of the rural population. The livestock sector plays a significant role in supplementing family incomes and generating gainful employment in the rural sector, besides providing cheap nutritional food to millions of people. Livestock provides milk, egg, meat as nutritious food, draught power for agriculture, wool, fibre, manure and domestic fuel, hides & skin. In 2010-11, this sector contributed 121.84 million tonnes of milk, 63.02 billion eggs, 42.99 million kg wool, and 4.83 million tonnes of meat. Milk is the main output of livestock sector accounting around two third (67%) of the total output by livestock sector. Meat and egg share 17.5% and 3.6% of the value of livestock output. Livestock contributed 4% to the total GDP and 26% to the agricultural GDP in 2010-11. Livestock are the best insurance against the vagaries of nature like drought, famine and other natural calamities.

1.1. Farm business management

Concerned with resource allocation.

Useful to impart knowledge and skill for optimizing the resource use and maximizing profit.

Farm electricity refers to the electrical systems and infrastructure used in agricultural operations to power various equipment, machinery, and facilities. The electrification of farms has become essential for modern agriculture, enhancing efficiency, productivity, and the overall management of farming operations. Description about the farm electricity:

Components of Farm Electricity

Power Supply: Farms are typically connected to the electrical grid, providing a reliable power supply. In some remote areas, farms may rely on off-grid solutions, such as diesel generators, solar panels, or wind turbines.

Power Distribution: Electricity is distributed across the farm through a network of power lines, transformers, and distribution panels. The distribution system ensures that power is delivered to various farm structures and equipment.

6.1 Hal for Land Preparation: This plough is constructed from Babool, sal, sisham wood, and mild steel. The body and handle are made from one piece, with a separate shoe. It is operated by one pair of bullocks with a yoke, weighs 48 lbs, and can cover 0.8 to 1 acre per day. It works to an average depth and width of 5 and 6 inches in alluvial soils, with a draught requirement of 185 lbs. It is used by 100% of the farming community in Meerut, Uttar Pradesh. (ICAR, 1960)

6.2 Wetland Plough (Dammu Nagali) for Land Preparation: This plough is made from Babool, palmyra, and mild steel, weighing 30-40 kg. Operated by two bullocks and one man, it is attached to the yoke with ropes for puddling rice fields, covering half an acre per day. It has a draught of 200-220 kg and ploughs to a depth of 4-5 inches and width of 5-6 inches in black and red soils. Repairable locally, its annual maintenance costs range from Rs 0.5 to 1.0, with an operational cost of Rs 25 per hectare. It is widely used in the coastal belt of Andhra Pradesh (Guntur and West Godavari). (ICAR, 1960).

8.1. Comparative advantage principle

Different areas or regions or farmers will tend to produce those products for which they have greatest comparative and not just absolute advantage.

Due to an extension and application of principles of specialization and diversification.

Each farm or region produces those crops or raises that livestock which it can grow more profitably

For example, farmers in Tamil Nadu specialize in sugarcane cultivation and those in Punjab specialize in paddy cultivation.

1.1 Some Useful Formulas Related to Farm Machinery

Farm machinery is a range of mechanical implements used in agriculture production from land preparation to harvesting and processing the produce. It includes various ploughs, tractors, broadcaster, harvester and post harvest processing machineries. The purpose of using machines in agriculture production is to handle the mass production, improve the efficiency and to save the labour costs. The types of implements used in fodder production are tillage, sowing, intercultural, plant protection and harvesting equipments.

25.1 Introduction

Farmers must be able to take appropriate decisions at appropriate time. Incorrect judgement and decisions will return in failure of execution of farm plan and in turn economic loss. The farm management decisions can be broadly categorised into two ways.

19.1 Introduction

The farm management comprises of two words: ‘farm’ and ‘management’. Literally ‘farm’ means a piece of land where crops and livestock enterprises are taken up under a common management and has a specific boundaries. ‘Management’ means the act or art of managing, the agricultural production or enterprises etc.

1. Introduction

The status of mechanization in India is at a very low level for horticultural crops. The farmers usually go behind the use of traditional methods for different farm operations (Fig 1) and practices for cultivation of horticultural crops, their handling, storage, and processing. This results in less yields, high cost of cultivation and high crop losses from harvesting till processing. The use of different available hand tools, machinery and hi-tech technologies in the production and processing of the crops will lead to increased yields and decrease in losses to a great extent (Mandhar, 1999).

Farm mechanization plays a crucial role in the evolution and efficiency of f loriculture, the cultivation of flowers and ornamental plants for gardens and f loristry. The introduction of advanced machinery in floriculture enhances productivity, reduces labor costs and ensures the consistency and quality of f loral products. Mechanization encompasses various stages of the floriculture process, including soil preparation, planting, irrigation, pest control, harvesting and post-harvest handling. Equipment such as automated seeders, transplanters greenhouse climate control systems, drip irrigation setups and harvesting machines streamline operations, leading to higher yields and reduced manual labor. Moreover, mechanized techniques facilitate precision farming, enabling growers to optimize resource use and minimize environmental impact. The use of drones and sensor technologies allows for meticulous monitoring of crop health, ensuring timely intervention and reducing losses due to pests and diseases. By incorporating mechanization, floriculture can meet the increasing global demand for flowers and ornamental plants while adhering to sustainable agricultural practices. Additionally, the adoption of mechanized processes supports the scalability of floriculture businesses, making them more competitive in the market. Thus, farm mechanization is instrumental in transforming floriculture into a more efficient, sustainable and profitable sector, aligning with modern agricultural trends and consumer expectations.

Introduction
Farm mechanization represents a pivotal shift in agricultural practices, marking the transition from traditional, labor-intensive methods to modern, technologydriven farming systems. This chapter explores the various dimensions of farm mechanization, highlighting its critical role in enhancing agricultural productivity, ensuring food security, and addressing the challenges of global warming. The chapter begins by examinin65g the different types of agricultural machinery and equipment used in modern farming. This includes tractors, plows, harvesters, seeders, and other essential tools that have revolutionized the way crops are cultivated, harvested, and processed. The mechanization of these processes has significantly increased efficiency, reduced labor costs, and improved the overall productivity of agricultural systems. Precision farming and remote sensing are discussed as integral components of modern farm mechanization. These technologies enable farmers to optimize the use of resources such as water, fertilizers, and pesticides, thereby increasing yields while minimizing environmental impacts. Key components of precision farming, such as GPS-guided machinery, soil sensors, and aerial imaging, are explored in detail, along with their applications and benefits. The chapter also delves into machinery management and maintenance, emphasizing the importance of regular upkeep and proper management of farm equipment. Effective machinery management ensures the longevity and reliability of agricultural machinery, reduces downtime, and lowers operating costs, all of which contribute to more sustainable and profitable farming practices. Farm mechanization is highlighted as a crucial factor in enhancing food security. By increasing the efficiency and scalability of food production, mechanization plays a vital role in meeting the growing global demand for food. The chapter discusses how mechanization extends growing seasons, improves crop quality, and diversifies crop choices, thereby contributing to a more stable and resilient food supply. The impact of farm mechanization on global warming is also a key focus of this chapter. While mechanization has led to increased productivity, it has also contributed to greenhouse gas emissions and other environmental challenges. The chapter explores strategies for mitigating these impacts, including the adoption

Farm Mechanization refers to the use of various mechanical, electrical, and hydraulic equipment and technologies in agriculture to perform tasks that were traditionally done by hand or with animal power. These machines and tools are designed to make farming operations more efficient, productive, and cost effective. Farm mechanization encompasses a wide range of equipment, from tractors and plows to harvesters and irrigation systems.

It’s important to note that while farm mechanization offers numerous benefits, it also presents challenges, such as the initial cost of machinery, the need for maintenance and technical knowledge, and concerns about the displacement of rural labor. As a result, the adoption of mechanization in agriculture varies widely by region and type of farming operation

Present Status of farm Mechanization in India

In India, farm mechanization has been a key focus for increasing agricultural productivity and reducing labor-intensive farming practices. Here are some key points on the status of farm mechanization in India:

1. Government Initiatives: The Indian government, through various agencies, has been promoting and supporting the adoption of farm mechanization. Schemes such as the “Sub-Mission on Agricultural Mechanization” (SMAM) have been launched to provide subsidies and f inancial incentives to farmers for purchasing agricultural machinery and equipment.

7.1. Farm planning

Decision making process in farm business

Involves organization and management of limited resources to realize specified goals continuously.

Selecting most profitable course of action from among all possible alternatives.

22.1 Farm Planning

It refers to setting the objectives and actions to be taken in directing or controlling the organisation of farm business and it precedes all other managerial functions on the farm to achive the desired results. It is deciding in advance to the production management problems viz. what to produce, how to produce, when to produce, financial management problems viz how to borrow, how much to borrow, when to borrow, from where to borrow and marketing management problems viz, where to buy, and sell, when to buy and sell, how to buy and sell ete. Farm planning governs the survival progress and prosperity of farm organisation in a competitive and dynamic environment. It is a continuous and unending process. Farm planning is as old as farming itself but mainly it uses the farmal planning.

1.1 Introduction

Water is the basis of all forms of life. It supports life system not only to the plants but also to all other animals. The embryo from the conception till birth floats in the liquid medium. Cell, the basic unit of life, contains as high as 95- 98% water. Cellular metabolism is controlled by content of water. Majority of this water requirement of the crops is met from different forms of precipitation. However, when the water requirement is not fully met from precipitation, then growth of the crops is affected. This results in reduction of yield of the crops. The reduction in yield depends on the amount of scarcity of water requirement of the crops. Water requirement of crops depend on many factors. It depends on the type of crops, irrigation schedules practiced, soil texture, position of groundwater table below the effective root zone of the crop and management practice followed in crop cultivation. The pulses, oilseeds, vegetables which are also otherwise termed as dry land crops need less water compared to rice which is a water loving crops and perennial crops like sugarcane and banana.

Water requirement of crops is partly met by the upward flux of groundwater. The capillary rise of shallow water table in the form of upward flux helps in meeting the water requirement of crops to some extent. The upward flux depends on the type of the soil, effective root zone depth of the crop, depth of water table below effective root zone depth of the crop and potential gradient of soil moisture suction. The residual soil moisture helps in supporting water requirement of crops also. The heavy soil like clay has more moisture retention capacity than the light soils like sandy soil. The residual soil moisture held in clay soil is released slowly and supports soil moisture to the crops for a longer period than the sandy soil which has less soil moisture retention capacity. After meeting the water requirement of crops from all sources including different forms of precipitation, ground water contribution by capillary rise and residual soil moisture, if there is any shortage of water, then this shortage should be met from other sources which is called as irrigation.

12.1 Introduction

Farm ponds are used for multipurpose including as a viable source for supplemental irrigation to rainfed crops, a good place of entertainment, a vital place for wild life habitats, livestock and fish and aquatic plants. Like any other structure, the farm pond needs regular repair and maintenance for effective operation. The purpose of construction of the pond will be fruitful and the life span of the pond will be enhanced if proper care and maintenance are taken. In this chapter some salient discussions on care and maintenance of the pond are mentioned.

12.2 Maintenance Against Silting

The farm ponds constructed in medium to deep black soils are subjected to getting silted up. Hence, periodic desilting to restore the original storage capacity is required. If the pond is used for supplemental irrigation to crops, then desilting may be done once in every 5 to 10 years depending on the amount of silt getting deposited in the pond.

The breaches and rill formed in the spoil bank and shoulder bunds should be immediately repaired. The inlet and outlet structures should be maintained periodically. The silt deposited in the silt trap should be removed periodically. In areas where silt carried by the runoff is more, a vegetative filter near the inlet structure may be used. The pond may be desilted manually if it is small in size otherwise mechanical measures may be used to desilt. It is easy to desilt the pond when it is dry. A Simple and inexpensive method to desilt the pond is to stir the water of the pond and then allow the desilted water move away from the pond through the outlet (Belgaumi, et. al., 1997). Fig. 12.1shows a badly maintained pond with excess silting and weed infestation causing severe reduction of its storage capacity.

Agricultural processing, often referred to as agro-processing, is the transformation of raw agricultural materials into products that are suitable for consumption or further manufacturing. This process adds value to agricultural products, enabling them to be stored, distributed, and marketed more effectively.

Agricultural Processing can Involve a Range of Activities, Including

Cleaning and sorting: Removing impurities, dirt, and unwanted materials from the raw agricultural produce.

Grading and quality control: Sorting products based on size, shape, and quality to ensure consistency and meet market standards.

Preservation and storage: Using various methods such as drying, freezing, canning, and refrigeration to extend the shelf life of perishable agricultural products.

ABSTRACT

Communication is now one of the central issues in developing societies. Knowledge expansion, information technology and technology dissemination are the three very important dimensions of any development system be it agriculture, industry and whatever. Revolutionary changes in communication policies, techniques and strategies are needed in order to make information is a fundamental right to the poor rather than making communication a privilege enjoyed by the rich and powerful. Transfer of agricultural technology generally aims at speedy diffusion of novel agricultural information from the place of invention to the place of adoption. In the current Information and Communication Technology (ICT) era, human dependency on computer and allied modern electronic gadgets for executing day to day activities is inevitable. All fields are being influenced by the interventions of ICT and agriculture is in no way an exception to it.

Indian agriculture is predominantly a rainfed agriculture under which both dry farming and dry land agriculture is included. Dry farming was the earlier concept for which amount of rainfall (less than 500 mm annually) remained the deciding factor for more than 50 years. In modern concept, dry land areas are those where the balance of moisture is always on the deficit side. In other words, annual evapo-transpiration exceeds precipitation. In dry land agriculture, there is no consideration of amount of rainfall. It may appear quiet strange to a layman that even those areas which receive 1100 mm or more rainfall annually fall in the category of dry land agriculture under this concept. The success of crop production in these areas depends on the amount and distribution of rainfall, as these influences the stored soil moisture and moisture used by crops. The amount of water used by the crop and stored in the soil is governed by the water balance equation: ET = P-(R+S). When the balance of the equation shifts towards right, precipitation (P) is higher than ET, so that there may be water logging or it may even lead to run off (R) and flooding (S). On the other hand, if the balance shifts to the left, ET becomes higher then the precipitation, resulting in drought in the various severity. Taking the country as a whole, as per meteorological report, severe drought in large area is experienced once in 50 years and partial drought in five years while floods are expected every year in one part of the country or the other, especially during rainy season. In fact the balance of the equation is controlled by the weather, season, crops and cropping pattern. Out of 142 million ha of net sown area in the country, rainfed agriculture is practiced in 95 million ha (67%). Nearly 67 m ha of rainfed area falls in the mean annual precipitation range of 500-1500 mm.

9.1 Farm Tools and Equipment for Horticulture and Plantation Crops

Agriculture in India is one of the most prominent sectors in its economy. Agriculture and allied sectors like forestry, logging and fishing accounts for about 14% of the GDP and employed 60% of the country’s population. About 43% of India’s geographical area is used for agricultural activity. Despite a steady decline of its share in the GDP, agriculture is still the largest economic sector and plays a significant role in the overall socioeconomic development of India. Nearly 80 percent of the farm population operates smallholdings, the average size of holding being 1.16 ha. Out of a total geographical area of 329 m ha, about 142 m ha constitute the net sown area. Nearly 63 percent of this area is rainfed and its contribution to the overall production is 44%.

A farm tractor is a versatile, heavy-duty agricultural vehicle designed to perform a wide range of tasks on the farm. Tractors are a cornerstone of modern agriculture, and they come in various sizes, power ranges, and configurations to meet the diverse needs of farmers and agricultural operations. Tractors are used for tasks like plowing, planting, cultivating, harvesting, and transporting goods on the farm. They are indispensable tools that have greatly increased the efficiency and productivity of agriculture.

The choice of tractor type depends on the specific needs of the farm, the type of crops grown, the terrain, and the available budget. Farm tractors continue to evolve with technological advancements, incorporating features such as GPS guidance, advanced hydraulics, and climate-controlled cabs to enhance efficiency and operator comfort.

Introduction

Agriculture is a major sector in Indian economy. It is one of the biggest production sector contributing more than 20 percent of GDP for India’s economy. Its is the largest provider of employment in Rural India. Over 70 percent household depends on agriculture. Its provides raw materials to industries and market for industrial product(Kekane, 2013).

Therefore, agriculture is a main sector for the planning of social and economic development of the country. Rapid growth of agriculture is essential not only to achieve self reliance at national level but also for household food security and to bring about equity in distribution of income and wealth resulting in rapid reduction in poverty line (Shrivastava et al. 2010). Agriculture is considered as the biggest unorganized sector where large numbers of women are working for their livelihood. The farm women comprise a quarter of the word’spopulation . Women also make up 41 percent of the word’s agriculture labour force, a ratio which rises to 49 percent for low income countries (ILO,2018).

Women play an important role towards the growth of the agricultural sector and its other associated areas. They perform multifarious tasks in agriculture and its allied fields. They are playing an important role in most of the farm operation like land preparation, seed treatment, sowing, planting, weeding, intercultural operation, irrigation of crop, application of manures and fertilizers, protection of crop, harvesting, threshing, storage etc. There is hardly any activity in agricultural production, except ploughing in which women are not actively involved. In some of the farm activities like processing and storage, women are dominant so strongly those men workers numerically insignificant (Patil and Babus 2018).Naidu et al. (2020) found that 63 percent of women are engaged in sowing of seeds and transplanting followed by in harvesting operation (61%), wedding (59%), winnowing (27%), manure and fertilizer application (25%) on regular basis.
