Abstract

Rural Indian women are extensively involved in agricultural activities and play a major role in agrarian scenario. Majority of the rural farm women are actively involved in various operations related to mixed farming system existing in India. Women and men participate in agricultural and animal husbandry practices as a family unit on the farms. Men perform major share of work quantitatively on agriculture side, where as on the animal husbandry side most of the management operations are being carried out by women in addition to their household activities. Dairy production is less influenced by rain failure compared to crops and is invaluable in sustaining family income during drought. Dairy development is now considered as an important tool for rural development or poverty alleviation. In fact, dairy farming occupies a special place in rural society with its linkage with religion and culture apart from providing sustained income. Most of the cattle and buffaloes are commonly kept in every farm household primarily for socio-economic reasons and more importantly for gaining drought power and as a secondary source of nutrition subsistence in the form milk and milk products for the whole family. In this context, a study was conducted in Karkala taluk of Udupi district with the major objective of studying the form and extent of participation of farm women in various operations of animal husbandry. The attempt made in this regard has revealed that rural women are fully involved in majority of the operations either as manual workers or as supervisors. Hence, it is suggested that for massive empowerment of rural women, animal husbandry programmes need to be launched as they are inherently profitable.

Abstract

Although women were not recognized as essential components of Agriculture for a long time, of late due recognition has been given to the role of women in agricultural production and steps have been taken to bring more and more women farmers into main stream, through Shree Shakthi Sanghas and Self Help Groups for women. Special projects aided by outside agencies and voluntary organizations such as WYTEP, IRDP, TRYSEM, DWCRA etc. provide training to farm women.These operations include selection and treatment of seed, protection of the seed or plant material, land preparation, application of manures and fertilizers, sowing or planting, nursery raising, irrigation, weeding, earthing up, pinching or thinning, training and pruning top dressing, plant protection, harvesting, transport and post-harvest operations such as threshing, winnowing, sieving, cleaning, drying, grading, packing and storage, joining hands with men etc. They also do marketing and disposal of the produce. For household use they take care in hulling, flowering, pounding etc.

Abstract

Bio-intensive pest management modules have been developed by the Project Directorate of Biological Control (PDBC) for management of pests on cotton, sugarcane, rice, citrus and several other crops. These modules lay emphasis on release of bio-control agents like parasitoids, predators and pathogens and reducing chemical pesticide applications to the possible extent. The pre-requisite of any bio-control programme is to have a large-scale supply of beneficial agents. It is at this juncture that women can play a major role. If the biocontrol strategy has to become popular, there should be reliable sources, which can assure timely and adequate supply of quality bio-agents for large-scale field releases. It would be most appropriate to educate farm-women on the importance of natural enemies and to provide them with incentives to start bioagent production units. Again, if the concept of biological control with the involvement of women has to succeed, massive educational programmes should be initiated. Women can become active participants at the village level mass production units, which could cater to the needs of farmers of different regions of our country. This could solve the problems encountered in long distance shipment of bio-agents. Besides creating awareness among women, these insectaries/production units can provide job opportunities for the rural and urban women.

A rotavator, also known as a Rotary Tiller, is a tractor-powered tillage tool used for oil cultivation. It works by cutting, mixing, and pulverizing the soil through a series of rotating blades. This tool is an affordable and efficient option for seedbed preparation and can replace equipment like disc harrows, cultivators, and levelers.
The rotavator features spinning blades that break through the soil, powered by the tractor’s PTO. It increases soil structure by breaking up clods, improving water absorption, and eliminating weeds and crop residue. Compared to a plough, a rotavator allows farmers to prepare land for sowing in fewer passes. As a powered machine, it ensures optimal soil conditions while helping to control pests and prevent crop diseases.
A rotavator or a rotary tiller is one of the most efficient tools used in modernday agriculture. It uses rotating blades and advanced machinery to pulverize the soil. According to several case studies, rotavators are considered one of the best economical and effective tools for soil bed preparation.

INTRODUCTION TO ROUTINE MAINTENANCE PROCEDURES FOR AGRICULTURAL DRONES
Regular maintenance of agricultural drones is crucial for their best performance and durability, as these sophisticated devices are integral to contemporary agriculture. Agricultural drones endure severe climatic conditions, such as dust, wetness, and fluctuating temperatures, which might impact their performance. Routine maintenance activities, including cleaning, inspecting, calibrating sensors, and assessing component wear, mitigate expensive downtime and guarantee that drones consistently provide accurate data for applications such as crop monitoring, irrigation management, and pest control. By following a regular maintenance schedule, farmers may optimize the dependability and effectiveness of their drone technology, so improving production and reducing the likelihood of malfunctions during essential activities.
UAV systems (drones) necessitate routine maintenance inspections to verify optimal functionality. They are susceptible to deterioration from prolonged usage, particularly when utilized within a bigger fleet.
This checklist may be utilized as frequently as necessary for routine maintenance inspections; however, it is more efficacious to conduct maintenance on a per-flight basis rather than at fixed intervals. Scheduling will more precisely indicate the likelihood of the drone requiring maintenance.
You likely already possess established procedures for determining when and how to conduct maintenance. Verify all items on this list to confirm their operational status and facilitate any required repairs or replacements prior to the next flight.

INTRODUCTION

Rubber cultivation in regions extending from 10°N to 10°S latitude is known as the traditional region and the areas other than its natural climatic origin is termed as the non-traditional region. Northeast India comprises majority of the non-traditional areas in India with major climatic constraints like high seasonal rainfall, excessive precipitation and to some extent dry conditions. These areas extending from 22 to 29^°N latitude, holds promise in extending rubber cultivation because of its exceptional climatic make-up and abundant amount of annual precipitation (2000 mm) distributed over a fair period of time.

This perennial crop generally yields latex rubber at the 7th year after planting (with an economic life span of 20 years), although the period (immaturity period) it requires, is higher in the non-traditional region (Rubber Growers Companion, 2006). This immaturity period has also been shown to reduce with water availability in sub-humid climates (Vijayakumar et al. , 1998). Harvest of this crop is by tapping. Tapping is a process of controlled wounding during which thin shavings of bark are removed, thus opening the latex vessels which exude latex. Dry rubber yield is obtained after the latex is coagulated and rolled into sheets (about 500gm) which is then smoked and dried.

3.1 Runoff

Runoff is one of the important parameter of hydrologic cycle. It is defined as that portion of precipitation which is not absorbed by the deep soil strata but finds its way into the stream after meeting the demands of evapotranspiration, interception, infiltration, surface storage, and surface as well as channel detention. It includes surface runoff received into the channels after precipitation occurs, delayed runoff that enters the stream after passing through the land surface, and other delayed runoff from the temporarily detained pits, depressions, swamps or detained as snow fall. It is thus the flow collected from the drainage basin and appearing at the outlet of the basin. The runoff process is demonstrated in Fig. 3.1 as flow chart. Details of the runoff process are discussed as below.

Abstract
The growing youth population in developing countries, particularly in agriculturedominated economies, presents a demographic dividend that remains underutilized due to skill mismatches and unemployment. Despite agriculture engaging nearly 50% of the workforce, it is often stigmatized as a low-skill profession, necessitating up-skilling and knowledge enhancement to transform it into a profitable, modern enterprise. Government initiatives in India, such as PMKVY, Start-up India, Mudra Yojana, ARYA, and Student Ready, aim to foster skill development and agripreneurship to align with global market trends. This paper examines challenges in leveraging this demographic potential, including outdated interventions and societal perceptions, and proposes visionary reforms to enhance training, promote equity, and mainstream agri-preneurship for sustainable economic development.

9.1. Rural Sociology

Science of rural society.

Study of sociological life in rural setting to discover their conditions and tendencies and to formulate principles of progress.

A.R. Desai: Rural Sociology involves the study of human relationships in rural situations.

Agriculture is the main stay of Indian economy as more than 60 per cent of the people of India are dependent upon this evocation and allied disciplines for their livelihood. Even today, at the dawn of 21st century, the Indian agriculture has continued to be the backbone of our National economy, representing countryís about one seventh of Gross Domestic Product (GDP). Thus, farming families consisting both of men and women, boys and girls, known as the pillars of our agriculture constitutes backbone of the Nation. The support and contributors made by the rural women in agriculture, consisting 50-60 per cent of farm work force are, however, not less than those performed by the men, and therefore they become spine of the rural economy.

The progress and prosperity of a nation depends to a large extent on well trained and disciplined youth. The youth of today are the adults of tomorrow and farm families of the future. More than half of the India’s population is below 35 years of age. Majority of these young people live in village where they do not have adequate opportunities for vocational training and formal schooling. This vast youth population has limitless energy and enthusiasm. The proper chanalization of this energy for constructive work can make India one of the most developed and prosperous nations of the world. Youth are the future of India, it is therefore, essential to harness them in an organized manner to build up the backbone of the country. If they are given good training they grow up as individuals-physically, mentally and morally capable of playing their full part as adult members of our welfare society.

Youth, defined as those who belong to the age group of 13-35 in the National Youth policy 2003 of India, is considered to be the most vital segment of the population. Across the globe youth is being treated as an asset for a country’s development and enormous investment is being made to develop the human capital. The challenge of nations like India with ‘Youth Bulge’ in their population is to channelize the energy into positive and creative development process. Youth in the 21st Century aspires for a just global order,  They are looking for democratic process in all spheres of life, whether it is education, employment or decision making.  The issues and concerns of youth are fast changing in tune with the technological innovations.

INTRODUCTION TO SAFETY PROTOCOLS FOR DRONE OPERATIONS
Drones in agriculture have transformed how farmers oversee and cultivate crops, enhance efficiency, and optimize resources. Nonetheless, like any sophisticated technology, the utilization of drones in agricultural contexts necessitates compliance with stringent safety measures to safeguard the operator, the surrounding environment, and the equipment. The size, power, and complexity of agricultural drones entail inherent operational hazards, including possible accidents, collisions, and interference with other equipment or humans. Implementing safety measures not only prevents accidents but also guarantees the accuracy and reliability of acquired data, hence optimizing the advantages of drone technology in agriculture. By complying with safety regulations, such as conducting thorough pre-flight inspections, establishing secure flight areas, and implementing emergency response protocols, farmers can mitigate risks while maximizing the benefits of drones in agricultural management.
Implementing safety guidelines for drone operations in agricultural environments is crucial to safeguard both operators and the ecosystem while optimizing technological efficacy. Drones serve as potent instruments for activities such crop monitoring, spraying, and soil health evaluation; nevertheless, inadequate management or noncompliance with safety protocols may result in accidents, equipment damage, and data integrity issues. The following are essential safety protocols to adhere to when operating drones in agricultural environments:

Introduction

Soils are formed by weathering of rocks and minerals and all soils contain some amount of soluble salts. Many of these act as a source of essential nutrients for the healthy growth of plants. However, when quantity and quality of salts in the soil near rhizosphere exceeds a particular value, growth, yield and/or quality of most crops is adversely affected. Such a soil is called salt-affected. The degree of adverse effects depends upon the type and quantity of salts, crop and its variety, stage of growth, cultural practices and environmental factors viz. temperature, relative humidity, and rainfall etc. Development of salinity and waterlogging is a serious problem in arid and semi-arid regions of the world and threatening the sustainability of irrigated agriculture.

Soil degradation resulting from salinity and sodicity is a major environmental threat to soil fertility and agricultural productivity in arid and semiarid regions of the world. Saline–sodic soils are degraded due to the simultaneous effect of salinity and sodicity. This causes loss of soil physical structure by clay swelling, and dispersion because of high Na+ concentrations in the soil solution or at the exchange phase. Apart from these physicochemical effects, this leads to biological properties, such as microbial respiration and biomass, becoming worse. On the other hand, salinity affects plant growth by creating osmotic imbalances and specific ion toxicities, which pose limitations to morphological, histological, chemical, biochemical, and metabolic processes. In turn, these reduce stomatal opening and photosynthetic rate, leading to decreased plant growth, crop yield, and quality.

Introduction

The coastal tract of peninsular India extends from Rann of Kutch in Gujarat to Malabar Coast in Kerala on the western coast and from Coromandal coast in Tamil Nadu up to Sunderban delta in West Bengal on the eastern coast. The eastern coast is generally characterized by a wider coast line when compared to its western counterpart. Coastal ecosystem in India occupies an area of about10.78 million hectares (1,07,833 km²) extending in nine states. It also occupies considerable area underLakshadweep and Andaman and Nicobar group of Islands. The extent and distribution of coastalarea have been shown in Table 1.

for limitation of world fresh water supply, farmland availability, salinity ingression and the pressing future need of food supply. The cultivation of salttolerant crops on saline soil and with saline waters has significant social and economic potential. It is often argued that fresh water agriculture near rivers and ponds was invented because of the need to sustain people and communities. Saline water agriculture is going to be needed for sustaining our future generations and civilization.
FROM DESALINATION OF SEA WATER TO SEA WATER AGRICULTURE
Sea water contains nearly 35000 ppm of dissolved salts. There has been great deal of interest world wide on desalination of sea and brackish water to safe drinking water. In early 1960s the young President of USA John Kennedy put forward two famous challenges for the scientists (1) Landing the man on moon and (2) Producing desalinated water at low and competitive cost. It is often said that the first challenge was met but the second one has been more difficult! With tremendous support and interest, work on desalination was taken up worldwide. Newer processes were being tried. At the Environmental Research Lab of University of Arizona and at Central Salt and Marine Chemicals Research Institute, Bhavnagar simultaneously solar powered HD (humidification – dehumidification) process of Desalination was developed and pilot plants were commissioned. It was however realized that desalinated water was costly and not easily applicable to most coastal communities, though for many countries in middle east with no alternative water source and cheap petroleum energy – it is applicable on a very large scale.

Saline Water Agriculture has been drawing interest as one of the solutions for limitation of world fresh water supply, farmland availability, salinity ingression and the pressing future need of food supply. The cultivation of salt-tolerant crops on saline soil and with saline waters has significant social and economic potential.

It is often argued that fresh water agriculture near rivers and ponds was invented because of the need to sustain people and communities. Saline water agriculture is going to be needed for sustaining our future generations and civilization.

There are four major tracts where salt affected soils are commonly met within India. These are:

1. The Semi-arid Indo-Gangetic alluvial tracts (mainly in Punjab, Haryana, Uttar Pradesh and a part of Bihar)
2. The arid tracts of Rajasthan and Gujarat.
3. The arid and semi arid tracts of southern states, particularly of the irrigated rigor (Vertisols) soils.
4. The coastal alluvium

Earlier it was estimated that about 7 million hectares of land have been affected by salinity/sodicity conditions in India. The area under these soils increased and reached to the level 10 million hectares at present.

11.1 Introduction

Salinity is the saltiness or dissolved salt content of a body of water. The technical term for saltiness in the ocean is halinity, from the fact that halides, chloride specifically are the most abundant anions in the mix of dissolved elements. In oceanography, it has been traditional to express halinity not as percent, but as parts per thousand (ppt ), which is approximately grams of salt per liter of solution. In other disciplines chemical analyses of solutions, and thus salinity is frequently reported in mg/L or ppm (parts per million). Prior to 1978, salinity or halinity was expressed as % usually based on the electrical conductivity ratio of the sample to “Copenhagen water”, an artificial sea water manufactured to serve as a world “standard”(Lewis, E.L 1980). In 1978, oceanographers redefined salinity in Practical Salinity Units (psu): the conductivity ratio of a sea water sample to a standard KCl solution (UNESCO, 1981a) (UNESCO, 1981b). Ratios have no units, so it is not the case that 35 psu exactly equals 35 grams of salt per litre of solution (UNESCO, 1985).

These seemingly esoteric approaches to measuring and reporting salt concentrations may appear to obscure their practical use; but it must be remembered that salinity is the sum weight of many different elements within a given volume of water. It has always been the case that to get a precise salinity as a concentration and convert this to an amount of substance required knowing much more about the sample and the measurement than just the weight of the solids upon evaporation. For example, volume is influenced by water temperature; and the composition of the salts is not a constant. Saline waters from inland seas can have a composition that differs from that of the ocean. For the latter reason, these waters are termed saline as differentiated from ocean waters, where the term haline applies.
