Abstract

Groundwater is one of the major sources of exploitation in arid and semi -arid regions of Rajasthan. To protect groundwater, its data on spatial distribution are important along with quantity. Analysis of quality of groundwater is also very important, because the physical and chemical characteristics of groundwater determine its suitability for agricultural, industrial and domestic usages. The importance ground water increases many fold for arid tracts like Western Rajasthan. Here quality of water is also matter of serious concern. Geostatistics methods are most advanced techniques for interpolation of Groundwater quality. The present study appraises the groundwater quality of western Rajasthan for agricultural purpose with GIS technology. Kriging Raster Interpolation technique of spatial analyst module in Arc GIS software has been used to generate the spatial distribution map of ground water for agricultural purpose. In western Rajasthan only 28% (58109 km2) of ground water falls under the category of good and is suitable for agricultural use. 

INTRODUCTION
The engine of a tractor is often referred to as its heart, as it drives the machine’s ability to carry out essential heavy-duty tasks in farming. As technology progresses and environmental sustainability becomes a key focus, it is increasingly important for Indian farmers in 2025 to understand the workings of tractor engines. This article aims to simplify the intricacies of tractor engines by covering their types, key specifications, performance features, maintenance, and recent innovations.
Tractors typically use diesel engines, which generate mechanical power through the compression and combustion of fuel. These engines are designed with a complex structure that ensures high power output and durability, which are vital qualities for the demanding work tractors are used for. To effectively meet these needs, tractor engines must be both powerful and built to last. These engines function based on the principles of compression and combustion of fuel. Here is a comprehensive analysis of their attributes and significance:
• High force: Tractor engines must produce significant mechanical force to execute diverse agricultural chores such as plowing, tilling, transporting, and other heavy-duty operations. Diesel engines are especially appropriate for this application due to their capacity to generate greater torque at reduced speeds, which is crucial for managing substantial loads.
• Durability: Tractors are frequently employed in severe locations, operating for extended periods under challenging conditions. Diesel engines are designed to endure the demands of continuous operation, making them preferred for agricultural machines. Their durable construction guarantees enduring reliability and longevity.
• Compression and Combustion: Diesel engines operate by compressing air within the engine cylinder. Upon the injection of fuel into this highly

Bunding is a traditional yet effective soil conservation method that involves constructing embankments or barriers along land contours to manage water flow and reduce soil erosion. These embankments, known as bunds, are particularly beneficial in semi-arid and erosion-prone areas, where water conservation and soil stability are essential for sustainable agriculture.
Bunds slow down surface runoff, allowing water to infiltrate the soil rather than washing away valuable topsoil. This not only reduces erosion but also improves soil moisture retention and supports crop growth. Bunds can be made from local materials such as soil, stones, or a combination of both.
TYPES OF BUNDING
There are several types of bunding, each with its unique features and benefits. Let’s explore the most common ones:
Contour Bunding
Contour bunding is a well-established soil conservation technique that involves constructing embankments along lines of equal elevation across sloping terrain. These structures, often equated with level terraces, are designed to intercept surface runoff, thereby reducing soil erosion and improving moisture retention in cultivated lands. Originating as a famine relief initiative in Maharashtra, India, contour bunding has since proven to be an effective and sustainable method for preserving agricultural productivity in hilly and semi-arid regions.
This practice is particularly suited to a wide range of permeable soils, including alluvial, red lateritic, shallow and medium black soils, as well as deep black cotton soils. However, challenges such as soil cracking in black cotton soils may compromise bund integrity, necessitating periodic repair and upkeep.

Terrace farming is a widely practiced agricultural method in India, particularly suited for hilly and mountainous areas. It involves shaping the landscape by carving out flat sections—known as terraces—into the slopes of hills or mountains. These levelled surfaces make it easier to cultivate otherwise steep and challenging terrain. This age-old technique, also known as step farming, creates a series of stepped platforms that resemble a staircase along the hillside. The approach is both practical and resourceful, allowing farmers to use sloped land efficiently for crop cultivation.
The primary motivation behind transforming large hill surfaces into terraces— despite the considerable labor it demands—is to control the rapid downhill flow of water that typically occurs in such regions. However, terrace farming comes with its own set of challenges. The soil on terraces often has limited water retentioncapability, and erosion can become more severe. Nutrients and soil particles tend to be washed away into rivers. In addition, if trees are cleared for farming, the land becomes vulnerable to landslides and mudslides during periods of heavy rainfall. Terrace farming is a prevalent agricultural practice in India, especially in regions characterized by hilly or mountainous topography. This method involves the creation of flat, horizontal plots—referred to as terraces—along the natural contours of slopes. These terraces transform steep, uneven land into cultivable platforms, making farming on such terrain more manageable and productive. Also known as step farming due to its resemblance to staircases carved into hillsides, this traditional technique is both efficient and adaptive. It enables the utilization of sloped land that would otherwise be unsuitable for agriculture. The primary reason for undertaking this labor-intensive process is to manage the rapid runoff of water common in elevated terrains. By interrupting the slope, terraces help slow water flow and reduce surface erosion. Nevertheless, terrace farming poses several challenges. The soil tends to have limited capacity to retain moisture, and erosion can still displace vital topsoil and nutrients. Furthermore, deforestation to create terraces can heighten the risk of landslides and mudflows during intense rainfall.

Abstract

Conventional wisdom holds that variability in rainfall represents a significant variability of agriculture production. But urbanization of the cities on one hand and climate change on theother hand areaffecting the agriculture. Surprisingly, there have been very few analyses exploring the link between rainfall variability and urbanization on agriculture production. Therefore an attempt is made in this paper to know the affect of rainfall variability and urbanisation on the cropping area. For this purposeNDVI analysis is carried out in the catchments of Osmansagar and Himayathsagar Reservoirs by using the medium to high spatial resolution multi spectral data provided by remote sensing satellites, such as Landsat TM, IRS-1C/1D LISS-III and IRS-P6 LISS-III has been used for the years1989, 1994, 1998, 2002 and 2008 for Kharif season, 1975, 1990, 1994, 1998, 2003 and 2008 for rabi season which is collected from NRSC (National Remote Sensing Centre). From this analysis it is found that the increment is more in rabi season compared to kharif season due to the increment of non-monsoon rainfall intensities and ground water withdrawal structures. The increased utilization of the groundwater is causing the reduction of inflows to the reservoirs in the recent years because whatever the rainfall that occurs in the catchment, first utilised for meeting the depleted soil moisture and ground water consequently reducing the surface runoff.

Introduction 
The Pleurotus species, belongs of the basidiomycetes class, are typically grown on non-composted lignocellulose substrates and have a shorter growth cycle compared to other types of mushrooms (Bellettini et al., 2018). These are shell-like fruiting bodies commonly known as “oyster mushroom” and also referred as “Dhingri mushroom” in India. The fanor spatula-shaped fruit body can be found in various colours depending on the species, including white, pink, yellow, grey, and blue (Verma et al., 2023). Their cultivation is popular due to the simple and low-cost methods. These mushrooms are highly favored not only for their taste, flavor, and pleasing texture but also for their nutritional and medicinal benefits (Sharma and Khanna 2019, Sarita et al., 2023). Pleurotus sp. are found naturally in both temperate and tropical regions across the globe which are cultivated more widely around the world due to their adaptable nature (Badshah et al., 2021). Despite their potential, India’s mushroom production has declined significantly, from 487 million MT in 2017 to 314.84 million MT in 2023 (Anonymous, 2023). Mushroom farming in Gujarat presents several opportunities due to various factors such as favorable climatic conditions, easy availability of raw material increasing market demand and supportive government initiatives. In India, rice straw is 80 Innovations of University Extension in Indian Agriculture mainly used as substrate for large scale mushroom production (Kundu et al., 2022). But, cultivation and consumption of mushroom were limited due to lack of awareness about the health benefits of this high valued food. However, by the efforts of KVKs under Agricultural Universities through the trainings and awareness programs, mushroom cultivation becomes popular among the people of Gujarat particularly in rural areas. Entrepreneurs and farmers can tap into this growing sector for profitable ventures, provided they are equipped with the necessary knowledge and resources.

Sugarcane (Saccharum officinarum)

Sugarcane is an important agro-industrial crop of tropical and subtropical region of the world. Sugar industry is next to textile industry provide employment to large number of people. It is the main crop of earning foreign exchange. It shares about 2% GDP.

Family : Gramineae (Poaceae)

Importance (Second largest agro-based industry)

• It is cash crop used for sugar, Jaggery (Gur) and Khandsari.
• Green top is used as green fodder. Dry leaves used as mulching and as a fuel.
• Bagasse (By product) is used as fuel, for the production of fibre board, paper etc. and for power generation (electricity).
• Molasses is used in distilleries for the manufacture of alcohol and is also used as an additive to feed livestock.
• Press mud is used as soil amendments, organic manure

Indian canes probably originated in the moist parts of North Eastern India from some plants closely related to Saccharum spontaneum (Barber, 1931). Brandes (1956) concluded that tropical cane might have originated in some of the larger islands of Oceania countries most probably in New Guinea, where various forms of thick, tall tropical canes have been grown from ancient times. Parthasarathy (1946) believed that India is the original home of Saccharum officinarum.

Introduction
 
Sugarcane is an important cash crop of India. Since 1930-31 the area of sugarcane in the country has increased by about 4.3 times and production by about 9.8 times because of the rise in productivity of sugarcane by about 2.28 times, however, during the last decade there is no perceptible increase in productivity of sugarcane in the country. The domestic demand of sugar is around 22-23 million tonnes annually whereas the production of sugar in India is about 26 million tonnes annually. Data on nitrogen use efficiency of sugarcane from 1998-99 to 2013-14 in India is depicted in Fig. 1 and 2 show a decreasing trend (Anonymous, 2015). However, the escalating price of fertilizers in the market has become a cause of concern to sustain the productivity of the crop.

Introduction
Sugarcane (Saccharum officinarum Linn.) is a remarkable tall, perennial grass characterized by its thick, jointed stalks and long linear leaves. This remarkable plant, known for its ability to efficiently photosynthesize in warm climates, is a C4 plant. The propagation of sugarcane primarily occurs through stem cuttings, as it seldom produces flowers and seeds. It finds roots in regions with tropical and subtropical climates featuring warm temperatures, abundant sunshine, and well-drained fertile soil (Shukla et al., 2017). Cultivated for its sweet juice, rich in sucrose, sugarcane serves as the primary raw material for the production of sugar, ethanol, and various other valuable products. Its lifecycle comprises several growth stages, including germination, tillering, grand growth, and maturation, culminating in the harvesting of its valuable juice. Continuous advancements in botany and genetics have contributed to the improvement of sugarcane cultivation, enhancing yield and resistance to pests and diseases. The origins and domestication of sugarcane can be traced back to Southeast Asia, particularly in regions encompassing Papua New Guinea, Indonesia, and their vicinity. The domestication of sugarcane is believed to have commenced thousands of years ago when early human populations in these regions recognized the sweetness of the cane and began cultivating it for its edible properties. Over time, through selective breeding and propagation of plants with desirable traits, these early cultivators played a pivotal role in shaping the sugarcane we know today. This indigenous Southeast Asian plant spread to other parts of the world through trade and exploration. Historical records indicate that sugarcane found its way to India around 500 BC and reached China in the 6th century AD. Subsequently, it traversed the Middle East, the Mediterranean region, and eventually reached the Americas during the early voyages of exploration and colonization (Grivet et al., 2004). Christopher Columbus played a significant role in introducing sugarcane to the Caribbean islands during his second voyage in 1493, and from there, it made its way to other parts of the New World, including Brazil and various South American countries. The cultivation of sugarcane emerged as an essential industry in these regions, profoundly influencing their economic and social landscapes. The domestication and widespread cultivation of sugarcane have left an indelible mark on the global economy, trade, and human history. Today, sugarcane remains one of the most significant crops globally, with major producing countries, including Brazil, India, China, Thailand, and others. It stands not only as a pivotal
