The Indian rain fed Agriculture is mostly dependent on onset of southwest monsoon and its behaviour across the country from June to September during the first crop season (Kharif). The monsoon sets on 1st June across the Kerala Coast and covers the whole country by 15th July (Western Rajasthan). The monsoon directory since last 151 (1870-2020)...

The management of weather and climate risks in agriculture has become an important issue due to climate change. The Intergovernmental Panel on Climate Change (IPCC) has highlighted multiple climate risks for agriculture and food security as well as the potential of improved weather and climate early warning systems to assist farmers. Wise use of we...

Assessment of plant-extractable soil water from experimental plots using infrared thermometer was carried out through a field experiment on rainfed castor beans (Ricinus cornnzunis L.) conducted for 2 years (1992—1993) at Hyderabad, India. The castor beans (cultivar: Aruna) were planted on three different dates in both years. Attempts were made to...

Field experiments on rainfed castor beans (Ricinus communis L.) were conducted for 4 years (1990–1993) to explain the variability in radiation use efficiency (RUE) and water use efficiency (WUE) in relation to meteorological parameters. In these experiments castor c.v. Aruna was sown on three different dates (treatments) in each year.The results fr...

A method of Response Farming Programme for managing risks associated with variable seasonal rainfall was developed for a semi-arid location using daily rainfall records for the period 1971-94. The risks are intense rains threatening soil erosion, prolonged heavy rains threatening water logging, prolonged low rainfall periods, early cessation of rai...

India is primarily an agricultural country, despite making rapid strides in industrialization in recent decades. The Indian economy is therefore highly dependent on the behavior of the summer monsoon, also known as the southwest monsoon, which occurs during four months (June–September). This accounts for 75% of the annual rainfall over most parts o...

Peninsular India is located in the tropics; its climate ranges from arid conditions in the rain shadow region (under the influence of Eastern Ghats along the east coast and Western Ghats along the west coast) to humid conditions in regions adjoining the west coast. The average annual rainfall in the region varies from about 500 mm in the interior p...

A field experiment was conducted during 1990 and 1991 to assess the PAR interception in castor (var. Aruna) during its growing period in relation to LAI. Daily values of PAR interception were influenced by cloud cover when leaf area index (LAI) was small. At high values of LAI, PAR interception was more as expected and was independent of the solar...

The concept of crop water use estimated with the help of FAO water balance model developed by Frere and Popov (1979) was found to be adequate to determine the crop yields under rainfed conditions. The relationship between crop water and use yield was established to be linear. The correlation coefficients between the observed and expected yields for...

Paper illustrates the methodology that can be used for determining the length of the growing season and its variability in relation to different dates of commencement of rainy season. The utility of the information for assessing the suitability of different crops and cropping systems is highlighted. The possibility of increasing cropping intensity...

The concept of water requirement satisfaction index was used to quantify the crop yield under rainfed conditions, choosing pearl millet as an example. The relationship between the water requirement satisfaction index and yield was observed to beY = exp (— 18.023+4.173 lnx), indicating the exponential behaviour of the yield as affected by the water...

This paper reports the design, development and testing of an improved multipurpose solar energy device. The novel feature of the device is that it can be used as a solar water heater and solar still simultaneously and, when required, as a solar cabinet dryer by incorporating minor changes.

The performance of wind mills relating the wind speed in km/h and water output in ha-mm as influenced by the swept area of the rotors and depth of the water table has been theoretically evaluataed and presented graphically. This graph can be conveniently utilized either to judge the suitability of any wind-mill in a given region or to optimise the...

The frequencies of occurrence of agricultural droughts in respect of pearlmillet and kharif pulses were worked out for three stations in western Rajasthan representing semi-arid, arid and extremely arid types of climates. Based on the minimum required values of AE/PE for these crops, the intensities of drought during different cropping seasons (195...

Drought is a recurring feature in the arid regions and prediction of droughts has got great relevance with respect to planning for afforestation, sand dune stabilisation, establishment of grasslands etc. Some attempts have been made at the Central Arid Zone Research Institute, Jodhpur to develop techniques for prognostication of droughts in the Ind...

The paper describes the performance study of two similar solar devices of different capacities which melt paraffin wax to manufacture candles. These devices are based on a flat plate collector system having the same absorbing surface area (0.25 m2) but different capacities of about 5.0 and 8.0 kg, respectively. It has been found that better results...

Studies on the effects of 8-yr old shelterbelt plantations indicate a general reduction in wind velocity, wind erosion and evaporative loss of moisture from protected fields. Cassia siamea shelterbelts are the most effective in checking wind erosion and delaying drying of the soil.-from Authors

Based on a rational approach, agricultural droughts were studied for the period 1901–75 for 5 selected regions in the Indian arid region using theAE/PE values during different phenophases. The productivity of pearlmillet and kharif pulses crops, the two major rainfed crops in this region, was assessed under different agricultural drought situations...

An improved hot box type solar cooker (SC-2) has been designed, developed and tested. It is an improvement on the solar cooker SC-1 earlier developed at the institute. The cooking chamber has properly been optimized for cooking the food for a family of five persons. A rubber gasket has been provided at the boundary of the openable door to prevent t...

A solar device has been developed for manufacturing candles from paraffin wax, utilizing solar energy. The design, operation and performance of the device have been described. It is concluded that the device can be used for saving fuel, minimizing the loss of wax due to the vaporization and labour.

A new method was developed for classifying agricultural droughts based on crops yields and index of moisture adequacy (AE/PE). It is found that in the arid regions of western Rajasthan, kharif pulses are more susceptable for drought than pearl millet. The method is based on rational concepts and can be extended to any region and to any crop.

The study showed that red sandy soils, laterite soils and medium black soils are suitable for the cultivation of kharif (monsoon season) crops, while deep black soils are suitable for double cropping with fairly good changes of growing rabi (winter) crops.-from Field Crop Abstracts

The probabilities of getting optimum sowing rains for long, medium and short duration varieties of ragiin Bangalore district were analysed on the basis of daily rainfall records often taluk rain gauge stations. The study reveals that the farmer cannot depend upon the same duration variety all the years and they have to choose a variety depending up...

The main rainfall, the coefficient of variation, the probability of getting a dry week and the probabilities of the weekly rainfall exceeding 0.5, I .0, 2. 0, 3.0 and 4. U cm ' during different weeks for the months April to December have been worked out using the rainfall data collected at Bangalore for the years J921 to 1970. The periods from 16 M...
