Samples for toxicological analysis are usually taken during post-mortem examination. In suspected cases of poisoning the following specimens should be sent for chemical analysis.

The Photosynthetically Active Radiation (PAR) measure of radiant power is important in evaluating the effect of light on plant growth. The photosynthetic response correlates better with the number of photons than with energy. This is expected because photosynthesis is a photochemical conversion where each molecule is activated by the absorption of one photon in the primary photochemical process. PAR is defined in terms of photon (quantum) flux, specifically, the number of moles of photons in the radiant energy between 400 nm and 700nm. One mole of photons is 6.0222 x 1023 photons ( 6.0222 x 1023 is Avagadro’s Number). The Phtotssynthetic Photon Flux Density (PPFD), i.e. the photon irridiance, is expressed in moles per squre meter and per second (formerly, Einsteins per squre meter and per second). The absorption of PAR by wheat varieties increased from 7.30 h to 11.30 h followed by a decline at 13.30 h at CRI, tillering and milking stages.

Abstract

In order to estimate the irrigation need of the crop, stress degree day index computers from canopy and air temperature could be used. During rabi manon, two varieties (Seeta, Brassica Juncea) and (Benoy, Brassica Camperteris) were grown. The canopy temperature of the crop was measured on 45th, 60th  and 75th  days after sowing and stress degree day (SDDI) was also measured. About 67, 70 and 51 per cent activation between SDDI and dry matter production could be explained at 45, 60 and 75 DAS of the crop growth period. Reflectance by mustard canopy was 940 measured. Late sown crop reflected less radiation with the advancement of growth. Extinction coefficient was also measured and the increase in the value of extinction coefficient upon irrigation showed canopy development and better utilization of increasing radiation by the crop. 

Back-Door Cold Front : A front moving south or southwest along the Atlantic seaboard of the United States.

Backing : A change in wind direction in a counterclockwise manner in the Northern Hemisphere and a clockwise manner in the Southern Hemisphere.
 
Ball Lightning : A rare form of lightning that may consist of a reddish, luminous ball of electricity or charged air.
 
Banner Cloud : A cloud extending downwind from an isolated mountain peak, often on an otherwise cloud-free day.
 
Bar : A unit of pressure, (usually the atmospheric pressure on) one is equivalent to a pressure of one million dynes per centimeter square one hundred kilopascals; 29.53 inches or 750 millimeters of mercury at zero degree Celsius.

Gale : Wind of force 8 or above blowing continuously and damaging trees, houses etc.

General Circulation : The average general distribution of wind in motion on the Earth. This general circulation includes the scientific description of atmospheric dynamics not only statistically but also from the point of view of physics. The global wind systems like westerlies, trades, etc., are the examples of general circulation.

General Circulation Model : At present, there are different models in vogue, to explain the general circulation of the atmosphere. If the general circulation is modelled in a three dimensional procedure, then it is known as a general circulation model.

Geopotential : The potential energy per unit mass of a body due to the earth’s gravitational field referred to an arbitrary zero.

Ice Caps : A perennial ice/snow cover over an extensive area of land or sea, found only around the two geographic poles.

Ice Columns : Ice crystals resembling stubby pencils rather than the delicate branched snowflake shape. Columns typically form in the temperature ranges -5° C to -8° C (23° F to 18° F) and below -25° C ( -13° F). They are long in comparison to their hexagonal cross-section.

Ice Crystals : 1) Hexagonal (6-sided) crystals that form upon freezing of water, may be in one of several shapes : stars, needles, plates, columns or combinations of these forms. 2) Precipitation in the form of slowly falling, singular or unbranched ice needles, columns, or plates, may be called diamond dust.

Ice Fog : Fog composed of minute ice particles that occur in very low temperatures (typically - 30°C or - 22°F & below) under clear, calm conditions in the polar latitudes. 

Nanometre : The unit of length specifically applied to wavelengths of radiation. This is equal to ten Angstrom units or 10-9 meters.

Net Assimilation Rate (NAR) : It is increase in dry weight of plant per unit leaf area per unit time. NAR is calculated from the following equation : 

Oasis effect : Vertical energy transfer from the air to the crop. It is the exchange of heat between a growing crop and hot air whereby air over the crop is cooled.
 
Observation : In meteorology, the evaluation of one or more meteorological elements, such as temperature, pressure, or wind, that describe the state of the atmosphere, either at the earth’s surface or aloft. An observer is one who records the evaluations of the meteorological elements.
 
Occluded Front : Also known as an occlusion, it is a complex front formed when a cold front overtakes a warm front. It develops when three thermally different air masses conflict. The type of frontal boundary they create depends on the manner in which they meet.

Ultraviolet Radiation : Ultraviolet radiation (UV) is one form of radiant energy coming from the sun. The sun emits a range of energy known as the electromagnetic spectrum. The various forms of energy, or radiation, are classified according to wavelength (measured in nanometers (nm) where one nm is a millionth of a millimeter). The shorter the wavelength, the more energetic is the radiation. In order of decreasing energy, the principal forms of radiation are gamma rays, X-rays, UV (ultraviolet radiation), visible light, infrared radiation, microwaves, and radio waves. Ultraviolet, which is invisible, is so named because it occurs next to violet in the visible light spectrum. Ultraviolet radiation contains the wavelengths between 30 and 400 nm. The UV band is divided into three sub-bands in regard to its biological impacts :

Vacuum : A space in which there is no air or gas. This is more an imaginary situation. This term indicate the air or any other gases at the minimum possible pressure in a space.
 
Validation : Model validation in its simplest form is a comparison between simulated and observed values. Validation is determining whether the model works with totally independent data sets or not and whether it accurately predicts growth, yield and processes by comparing the values predicted by the model with those obtained from the real experiment.

Structure of matter: every structure is made up of elements. Elements can join together to make compounds. The smallest particle of a compound is a molecule. The periodic table gives details of all elements.

Nucleus: the center of atom containing protons and neutrons and hence almost whole mass of the atom. 

Atom: the smallest units of matter composed of electrons are negatively charged, protons have a positive charged and neutrons are neutral. If there are more electrons atom will be negatively charged, if there are more protons it will be positively charged. The total charge of electrons is equal to protons and hence the atom is electrically neutral.

To understand how radiographs are produced by using X-rays, an understanding of how photons of diagnostic range can interact with matter is necessary in five possible mechanism of interaction:
    ·    Coherent scattering.
    ·    Photoelectric absorption.
    ·    Compton scattering.
    ·    Pair production.
    ·    Photodisintegration.

A tube rating chart is a guide regarding operational limits of the X-ray tube for single and multiple exposures and permissible heat load of the anode and the tube housing. It is an essential component for obtaining diagnostic X-ray examinations is a consistent way.
 
The tube rating chart provides important information on the maximum safe exposure time that can be used with specific mA and kV setting. If lower than designated exposure times are used, tube damage may occur. The size of the anode focal spot determines the rating of the tube because size controls the amount of energy it can absorbs and convert into X-rays and heat. Therefore, one should never use an X-ray chart formulated for another X-ray machine (even those made by the same manufacture) without making appropriate changes. Knowledge of three charts is important to extend tube life and includes tube rating chart, anode heat cooling chart and housing cooling chart.

X-ray photons are produced as a result of electrons hitting metal while extremely rapidly moving at high speed. This is achieved through the application of an electric current to a cathode (negative electrode) via a high voltage power source (electricity) which enables electrons to be released from the cathode into the X-ray tube. These electrons, being negatively charged, are attracted to the anode (positive electrode or target). When the electrons strike the metallic target (anode) in the tube, X-rays and heat are produced. Basically the process of producing an X-ray involves a source that produces X-rays and radiating them through a body or object, where they are absorbed at different rates until they are detected by a sensitive film or cassette. It should be mentioned at this point that most of the energy of the electrons is not converted into X-rays but is dissipated as heat. In fact 99% of the energy dissipated in the target is lost as heat, and only 1% is converted to X-ray energy.

To set up of an X–ray (radiology) section following points should be considered while planning:
 
    1.    Anticipated present work load (number of cases and species of animals to be X-rayed) and future requirement in the next 10-15 years.
    2.    Financial resources available.
    3.    Type of equipment to be installed for radiographic work.
    4.    Requirement of radiation safety enforcing agencies e.g. of Bhaba Atomic Research Centre, Mumbai.
The overall set up of radiology section should consider the following requirements:

A diagnostic radiograph is defined as one showing the tissues adequately penetrated, sharply outlined, and the variations in tissue opacity sufficiently demonstrated. An ideal diagnostic radiograph should have excellent detail, correct density and proper scale of contrast. The sharpness of the image determines the detail or definition of an image. There are two factors in radiographic quality control, viz: photographic and the geometric effect.  Density, contrast and detail are photographic aspects of radiographic quality. Detail and distortion are geometric aspects of radiographic quality. Because a radiograph is a two-dimensional (2-D) image of a three-dimensional (3-D) object, the appearance of a radiographic image varies with the patient’s orientation in relation to the primary X-ray beam. 

One of the most important pieces of information in the field of  X-rays is a radiographic technique chart. If one select exposure factors from a good rating chart, consistent radiographic examinations of diagnostic quality will be obtained. In addition, there will be a saving of X-ray films because waste from repeated exposures will be avoided.

There are several types of techniques chart that can be formulated, each type must be formulated with the goat of maximum potential of a particular X-ray machine. Perhaps the most popular type of technique chart used by veterinarians is a variable kilovoltage technique chart. A variable mA second chart is probably more appropriate for the most powerful X-ray machine. However, combination of variable kilovoltage and mAs technique chart is best. Such charts take into consideration the need to adopt a technique chart for different body systems, such as a thoracic and abdominal study, as well as examination involving the musculoskeletal system. The principle of how to prepare a variable kilovoltage technique chart along with an example of such a chart is given.

Artifacts are any unwanted radiographic densities in the form of blemishes arising from improper handling x-ray film, exposure, processing, housekeeping or setting up a technique for an examination. Artifacts will reduce the overall quality of the radiograph and in certain cases may nullify its diagnostic outcome. An idea about the possible errors is desirable in order to adopt corrective measures.

Forage preservation as silage is a key component of high input (zero-grazing) systems (Mannetje, 1999). It has allowed producers to intensify the productivity of the land and the productivity of the livestock. Large quantities of forage can be conserved in a short time, forage conservation is less weather dependent and thirdly, silage is well suited to mechanization. However, a major disadvantage associated with silage making is that the feeding value of the resultant forage is reduced relative to that of the original crop. Ensiling offers many advantages over haymaking.

Operation theatre (OT) is a place where surgical operations are performed under the principle of aseptic surgery. An ideal operation theatre :
    Should be located near the work and intensive care areas of the hospital.

    Should be independent of general traffic. One way traffic flow is maintained to ensure sterility. 

    If possible, air within the OT should be under mild positive pressure so that when the surgery room opened, air flows out of rather than into the room.
 
    Floors, walls and ceilings should be constructed of impervious material that can easily be cleaned and disinfected.
 
    The lighting of the OT should entirely be dependent on artificial light.
 
    Room temperature should be about 70^ºF with a relative humidity of about 50% provides a better environment for the surgeon and patient.

These instruments are used for different surgical conditions of hoof.
 
    1.    Drawing knife: It is used to remove excess sole and trimming of horny tissue (Fig. 6.1). 
    2.    Hoof plane: it is used to plane the surface of the hoof. 

Restraining means use of strong force or chemical agents to prevent or suppress or to control the action of animal for clinical examination or for prevention of self-injury and for performing surgical interventions.
 
Restraining can be performed by:
    1.    Psychic persuasion 
    2.    Physical restraint 
    3.    Chemical restraint

General anaesthesia can be induced by parentral anaesthetics or by gaseous or inhalation anaesthetics. 

Apparatuses

    1.    Syringes : Disposable plastic syringes of different capacities e.g. 1ml, 2ml, 5 ml, 10 ml, 20 ml and 50 ml.
 
    2.    Hypodermic needles : They are of different sizes e.g. 16, 18, 20, 22, 24 gauze. They must be sharp with short bevel to reduce risk of transfixing the vein.
 
    3.    Catheters : They are used for constant infusion of drug or for administration of intermittent small doses of drug. 

Preparation of Patient for General Anesthesia
    1.    Check for feeding status of animal : Dogs should be kept off feed and off water 8-12 hours ruminants 24-48 hours, and horses 12-24 hours before surgery.

        Advantages
    a.    To avoid vomition and choking.
    b.    To avoid respiratory distress due to pressure of full stomach on diaphragm. 
    c.    To avoid gastric rupture.
    d.    While restraining, there may abdominal rupture.
    e.    Prevent increase in BMR.
    2.    Complete blood count like PCV, Hb, DLC and blood chemistry should be undertaken. 

The effects of anesthesia need to be monitored to prevent excessive insult to the cardiovascular, respiratory and central nervous system. 

1. Evaluation of Central Nervous System (CNS)
       Observe reflex activity to monitor degree of CNS depression. 

    Eye reflexes
        i.    Palpebral reflex 
        ii.    Corneal reflex 
        iii.    Position of eye ball 
        iv.    Nystagmus
        v.    Lacrimation 
        vi.    Pupillary reflex

Hemorrhage is a discharge of blood from the vascular system. Control of bleeding is of great importance because besides anesthetic problems the only disaster befalling the surgeon in the operating room is the result of hemorrhage.

Hemorrhage is Classified as
1. According to Source
Arterial : Blood is bright red and flows in spurts.
 
Venous : Blood is bluish red and flows freely. Capillary: Blood oozes under low pressure. 

Many anesthetic drugs are available to immobilize the lab and wild animals. In wild animals, immobilizing agents are usually administered by intramuscular injection.

Common Anesthetic Agents used for Immobilizing Wild Animals

    1.    Ketamine
    2.    Telazol
    3.    Xylazine
    4.    Medetomidine
    5.    Carfentanil
    6.    Etorphine

    1.    Trocar and canula : It is used to remove the gas from the rumen during bloat. It should be inserted by sliding the skin through the left paralumbar fossa. (Fig. 18.1). Sliding of skin decreases the chances the formation of ruminal fistula after its removal.

    2.    Probang gag : It is made of a wooden piece with a hole in the middle and straps on either ends. Wooden block having the hole is fixed in the mouth and straps are fastened behind the horn at the poll. The probing is passed through the hole in to the stomach (Fig. 18.2).

Abstract

Data pertaining to 1761 records on daily milk yield and 1416 milk samples for estimation of fat and SNF percent in Banni buffalo during the year 2008-10 were collected from the breeding tract under In-situ conservation project on Banni buffalo and utilized for present study. The overall means ± SE for daily milk yield was 09.86 ± 0.07 lit. The month-wise daily milk yield was observed highest in second month, followed by 1st (12.96 ± 0.19 lit), 3rd (12.73 ± 0.19 lit), 4th (11.66 ± 0.20 lit), 5th (10.81 ± 0.25 lit), 6th (09.77 ± 0.23 lit), 7th (08.58 ± 0.18 lit), 8th (07.26 ± 0.17 lit), 9th (06.15 ± 0.11 lit), 11th  (05.70 ± 0.10 lit), 10th (05.41 ± 0.09 lit), 12th (05.78 ± 0.08 lit) and 13th  (05.48 ± 0.63 lit) months of lactation. The data on milk constituents’ viz. fat and SNF percent was grouped according to the seasons of the year and morning – evening milking.

Snow is precipitation of solid water, mainly in the form of branched hexagonal crystals or stars. It is “precipitation of white opaque grains of ice”. Measurement of snow cover is related to runoff estimation and also important for hilly agriculture.

4.1. Snowfall

It is the amount of fresh snow deposited over a specified period (generally 24 hours). The measurements relate to depth and water content of the snowfall.

The surface of the earth gets heated up during the day and gets cooled during the night causing diurnal changes in the top layers of the soil. Soil temperature is an important part of micro-environment, where plant roots grow and capture the water and nutrients and thus, it affects the plant growth and yield. During crop germination also soil temperatures play vital role. Since the heat regimes of these layers are governed by the soil temperature, the measurement of soil temperature becomes extremely important.

It is the actual minimum temperature experienced by the plants near ground surface. The grass minimum temperature is lower than the air temperature at 4 ft level. It is the temperature recorded in open air ground on short turf, with the bulb of the thermometer just in contact with the tips of the blades of grass. It is also described as the temperature at 5.0 cm (2 inches) above ground. It is used during October to March period only when frost occurrence is expected. The readings of the grass minimum thermometer indicate the possibility of ground frosts, which is important information for farmers, gardeners and growers.

Cloud is a visible aggregate of minute water droplets and/or ice particles, or both in the air usually above the general ground level. Clouds are the most important form of suspended water droplets caused by condensation. There is no precipitation without clouds.

11.1. Measuring Instrument

The cloudy hours are measured with the help of eye or sensory parts of the body. No particular instrument is required for cloud amount or cloud cover measurement in the sky.

Photosynthetically active radiation (PAR) is the radiation in the 400-700 nm wave band. For plants, 400-700 nm wave band of the light spectrum is very useful because of photosynthesis activity in this band. A simple integral relationship exists between the number of molecules changed photo-chemically and the photons absorbed within the requisite wave bands regardless of photon energy. Net photosynthesis rates are found to be almost linearly proportional to the radiation intercepted, which can be measured by line quantum sensor.

Weeds have some characteristics as follows:

    1.    Weeds are hardy and can grow under adverse edaphic (Soil), climatic and biotic condition.
      Example: Lantana camera,Eupatorium adoratum etc.

    2.    Weeds in general prolific with abundant seed production potentialities.
        Example: Amaranthus viridis, Chenopodium album etc.

No plant in the earth is completely worthless. Weeds have also some beneficial effects although they do much harm in different ways. The beneficial effects of weeds are as follows:

    1.    Most of weeds absorbs nutrient from the deeper layer of soil. When such weeds are incorporated in the soil, they add organic matter content of the soils. As a result, the fertility of plough layer from where plants absorb most of their nutrients is enriched.

    2.    Weeds help in controlling erosion by the soil binding effects of their roots and by forming a living mulch, which resist beating action of rain drops and sweeping action of wind.

Dispersal means the spreading of weeds from one place to another place. Dispersable of weeds generally takes place through seeds and vegetative parts. Dispersal of mature seeds and live vegetative parts of weeds is nature’s way of providing non-competitive sites to new individuals.

    (a)    Dispersal of weeds through seeds: Seeds are protector and propagator of their kind. Weeds seeds remain viable for a long time and their dispersable mainly takes place through natural and human agencies.

Abstract

The Stree Shakthi Groups (SHGs) were launched in Karnataka during 2000-01 aimed at improving the overall development of rural women in Karnataka. A review of the progress achieved by these illeterate or less educated, hither to continued to be economically dependent with no voice in decision making, is nothing short of a miracle. With an enrollment of one and a half million in 5000 villages, their savings and borrowings run into hundreds of crores and employment opportunities are provided to lakhs of farm women. Apart from agriculture related activities, some of them have also involved in some unconventional, income generating activites. Economic empowerment has emboldened these beneficiaries to not only fight against social evils but also win their battles. Overall, SHGs have transformed the life of rural women treatmendously in a positive direction.

Abstract

The present study was undertaken to analyse factors contributing to participation of rural women in Self Help Groups (SHGs), constraints faced by them and to elicit their opinion to strengthen the role of SHGs. The finding has revealed that, majority of the respondents has suggested that they should be provided with loans and the rate of interest on loans should be less.  Further, they also suggested that instead of existing loan structure from the bank and saving amount within the group must be increased which can be invested on other activities. It was also reasoned that the provision of low interest loan from the banks and purchase of raw materials at cheaper rate can improve the financial status of farm women.

The World is a home to more than one billion young people aged between 15 and 24 years.  Many are unable to fulfil their potentional because of poverty, hunger, poor health and lack of education. As a result, they lack the skills needed to gain employment, with rural youth typically, but often fruitlessly migration in search of economic opportunities. However, given support and opportunities for gainful employment, young people have the potential to play a significant role in agriculture.

India has a big advantage as more than half of its population is below 30 years of age.  Indian agriculture will receive a big boost if the country takes advantage of its young population and encourage them into farm sector by making it lucrative.  It is necessary to launch a Youth for Agricultural Transformation Movement in rural India. Youth can provide demand driven services such as farm health monitoring and marketing of biological software essential for sustainable agriculture, climate-risk management, organization  of bio-parks, food parks, bio-village, bio-industrial watersheds and improved post-harvesting technology. Educated rural youth can establish Village Knowledge Centres (VKVs) to provide information at right time to farmers. Home Science graduates can establish nutrition clinics to help hidden hunger through appropriate local grains and vegetables (Swaminathan, M.S.). Why Youth in Agriculture?

Youth in India had been at the forefront of the nation’s struggle for freedom and development. There are over one billion youth in the world today. Eighty five per cent of these youth live in the developing world and around 50 per cent of the population with in developing countries live in rural areas. According to 2001 census, more than 40 per cent of the total population is between the age group of 15 to 35 which is considered as “youth” by the Government of India. Out of which, 73 per cent resides in the rural areas (Anonymous 2001). Unfortunately rural youth of today are counted among the most disadvantaged groups of society. Because of rapid population growth, widespread unemployment inadequate health, poor education, migration, lower family income and lacking adequate opportunity at farm level had led the rural youth in continued stress of self esteem and self confidence. Youth empowerment is an attitudinal, structural and cultural process whereby young people gain the ability, authority and agency to make decisions and implement change in their own lives and the lives of other people. Youth are the present and the future of humanity.

India has the second largest concentration of tribal population after African continent. The tribal population of India is more than 8 per cent of the total population (Anonymous 2001). However, in Maharashtra it is over 9 per cent of the state population. Among the tribal community Bhil community is the largest tribal population in Maharashtra. They live in compact areas, which are generally hilly and undulating terrain. The Bhil are primarily farmers, though they are said to be hunters since the past. Poor condition of soil, small holdings, poor resources and economic condition, traditional methods of agriculture do not provide them a regular and continuous sustenance throughout the year as such they have to depend on other subsidiary sources of earning.

Most of the tribal communities have to live under a difficult economy; the ways of their livelihood are limited and work very hard to get a bare subsistence. Thus, the tribal children from their early age are burdened with a number of economic duties, obligations and they can hardly be spared for school. Proportion of dropout is also higher among tribal children. In fact most of the tribal youth and school going children participate in farming and looking after the economic demands of the family.

Agricultural research in India has contributed new varieties of crops and production technologies for increased production at the national level. These modern technologies benefited only a particular section but farm youth in rainfed areas are facing many problems. One of the problems identified in the diffusion of technologies to farm youth in sustainable agriculture was the lack of appropriate technologies suitable to the farm and social situations. When farmers in rain fed areas are exposed to innovations, they react to the practices/innovations from different viewpoints. A practice appropriate to farm youth in rain fed areas must be less in cost, high in profits, less risky,  highly compatible with socio-cultural values and beliefs, less in complexity, highly trialable on a small scale and the results of the same should be easily observed and communicated. These dimensions are perceived by farmers differently and the degree to which they perceive them favourably are likely to adopt the same in rain fed areas. Many a time, several past investigations have only indicated whether the recommended package of technologies has been adopted or not by farm youth. This gives percentage of farm youth adopting the practices but not the percentage of recommended technologies adopted by them and the problems encountered by them in adopting the recommended technologies in rain fed areas.

ICT refers to tools that facilitate production, transmission and processing of information. It includes the gadgets and processes to access, retrieve, store, organize, manipulate, produce, present and exchange information by electronic and automated means. According to UNESCO (2004), Information Communication Technology includes a range of technologies starting from radio, television, up to modern technologies like mobile phone, multimedia, internet, and satellite based communication systems. Modern information and communication technologies that have resulted from a breakthrough in information technology, when applied to conditions in rural areas, can help to disseminate information, improve farmers’ knowledge, increase their participation and share knowledge with others. Information Communication Technology (ICT) is one of the yardsticks to measure socio-economic development of the country and hence effective usage and management of ICTs tools is the pre-requisite for any development. Telephone is a powerful electronic device. The number of rural telephones was increased by approximately 35 per cent per annum (Jhunjhunwala and Ashok, 2005). This impressive growth in telecommunication sector is being utilized to provide information on demand to the farming community with the establishment of “Kissan Call Centers” (KCCs).  Kissan Call Centres were launched in January 2004 across the country to provide information services to the needy farmers and answer the queries made by them through telephone. In this context, a study was conducted to find out the profile of Kissan Call Centre users.

Relevance of Gender Mainstreaming  in Agriculture

Indian agriculture is characterized by farming systems wherein men and women perform mutually interdependent as well as independent roles right from production, processing, marketing, and decision making as farmer, labourers and entrepreneurs. The extensive contribution by women in wide ranging tasks in production and processing in agriculture, influences household food security and determines national competitiveness in agro industry at large. Even though women make substantial economic contribution towards the sustenance of the farming systems and livelihood security, most often women’s roles remain invisible and their problems and needs are unaccounted and unattended. Historically dictated by social norms, family traditions and economic factors, participation of women and men in various farming contexts in India still remain gender specific and highly women discriminating. Women’s work is considered as unskilled and remains undervalued and underpaid. It is to be appreciated that at international and national level efforts of women empowerment and gender perspectives are being brought in development approaches and the situation during the past few decades is slowly changing as policies, efforts and budget are being specially allocated for the upliftment of rural farm women. But it is to be noticed that most of the programmes are of short term, narrow focussed and without continuity.

Agriculture is of paramount importance in most developing countries because large proportion of the population involved and the need to maintain national food production. It is generally accepted though not fully proven, that health and productivity are positively correlated. This is of particular  relevance because many agricultural tasks in developing countries demand high level of strenuous activity (Anonymous, 1987). Investment to improve agricultural worker’s health would be justified on both humanitarian and economic grounds. Nearly half of the available human resources in India are women.  It has been roughly estimated that women represent 50% of population and have contributed about 10% of income and own less than 1 % of the world’s property.  The population of farm women are involved in sowing, transplanting, weeding, winnowing, drying, bringing drinking water and firewood, cleaning and dehusking.  Most of the drudgery prone tasks for women in agriculture are cutting uprooting, transplanting, weeding and sowing and post harvest tasks like manual threshing of maize, millets and pulses, sieving and cleaning. For groundnut, after the harvesting, removal of nuts and cleaning of groundnut seeds are also performed  manually. Further, sieving, cleaning are performed by winnowing followed by traditional sieve. (Badiger et al. 2006).  Studies have pointed out that farm activities that are time and labour intensive, monotonous, repetitive and more drudgery prone are generally performed by women.

India is one of the countries where 90% of the small, marginal and medium land holding farm families are depending on agriculture. The average annual income of the each farm family isvery less from the agril sector. At present farmwomen play an important role in managing different kinds of farm and home activities. The entrepreneurial behaviour development among the farm family is very essential to earn the additional income to manage their family. Farmwomen not only are involved in home activities but also play a significant role in farm production. In India farmwomen take decisions in their day-to-day life in agricultural sector. However, farmwomen are greatly aided by the amount of information available to them about their felt needs.  The World Bank Report(1992) states that keeping the role of farmwomen in mind, there is a need for training of farmwomen regarding necessary dairy technologies, so that they can perform these activities with more competence.
 
The advances in information technology have brought an explosion in information flow like Radio, T.V, Internet etc in agriculture.  There is large quantity of information through various sources, channels and Website on the Internet, but the information tends to be one sided, as it is gathered from Research stations. Farmwomen seek information sources.  Therefore, a study was conducted to understand the information seeking behaviour of dairy farmwomen.
 
The study was conducted in Manvi and Deodurga taluks of Raicur district in Karnataka state to know the information seeking behaviour of farmwomen regarding dairy farming and allied sector.

The efforts to keep pace with the fast life are causing mental and physical tensions. Diversion and relaxation is needed for the revival of spirit and enthusiasm. Leisure is an unimposed free time, after the practical necessities of life have been attended to. It is the time spent in activities chosen by the individual rewarding for its own sake. Choice of leisure time activities may also depend on the regularity of free time. An activity performed during small amounts of free time may be different than the one planned for a large block of free time. The leisure activities have far reaching influence on the personality development of the youth. If these youngsters are trained to make use of their leisure time for productive purpose, their endless energies could be channelised into fruitful development work.

An investigation was carried out involving 120 rural youth from Kapasi and Mardasgaon villages in Gangakhed taluka of Parbhani district from marathwada region of Maharashtra state, to asses the leisure time utilization by rural youth.  The sample included 70 boys and 50 girls.

Profile of Rural Youth

Education : As regards the education of female youth is concerned, 30 percent of them were educated up to H.S.C. and S.S.C, level where as 20 percent of them were educated up to high school level and 10 percent of them were degree holders and educated up to middle school level.

Youth are the creative force potential and a strength symbol for every community. One of the hallmarks of the positive youth development movement is that it is built on a foundation of scientific research. In addition, youth development programs typically work through existing social organizations rather than focusing on individual counseling. The rural youth work of FAO over the years has made significant contributions to make the lives of young people from rural areas more productive and meaningful by strengthening the organizations which serve them. The needs and challenges of rural young people today are greater than they have ever been in the past. In most developing countries, youth make up well over one-half of the total rural population. Because of their number and potential impact, rural youth must be a major part of any equation dealing with immediate and long-term solutions to solving problems of food security and sustainable development. Rural youth living in rural areas get limited opportunities for educational attainment in village areas. Opportunities for vocational guidance are also limited causing them diverting towards non creative activities and for merely wastage of time. An investigation was undertaken to study the socio-economic characteristics  and leisure time activities of rural youth. The study was conducted in College Development Block comprising Hatkanangle, Radhanagari & Bhudargad Tahsils of Kolhapur district, Maharashtra. From the Tahsil, 10 villages were selected randomly.  From each village, nine rural youths were selected randomly. Thus in all 90 rural youth were finally selected for the study. 

The silkworm chawki rearing is a vital stage in rearing as it has major influence on cocoon production.  Temperature, humidity and leaf quality are the three key important factors influencing chawki rearing.  Hence, maintaining these conditions at every step is very important and calls for provision of separate chamber. Any alteration in these factors will influence during later ages of silkworm rearing leading to crop losses.  Taking these factors into consideration the Government of India promoted the establishment Chawki Rearing Centres (CRCs) in private sector also.  These CRCs brush the silkworm eggs at one point under controlled conditions and distribute the worms to the needy farmers.
 
In recent years, bivoltine hybrids are becoming more popular in India and particularly in Karnataka.  This is due to the efforts of the Central Silk Board, Karnataka State Department of Sericulture and Japanese International Co-operation Agency.  These Bivoltines have high cocoon shell ratio (24 to 25%), better quality, fetches high cocoon price, better returns, high rendita (5.1 to 6.1) and raw silk percentage (20 to 22%) with filament length of 11502 to 12200 meters.  The farmers could achieve up to 70kgs cocoon yield per 100 Disease Free Layings (DFLs) and quality silk of 2A to 4A grade.
