Contribution to the scientific advancement
- Examined the economics of oilseed crops under varied agro-ecological situations and assessed the extent of input and yield gaps and examine the farm level constraints confronted in the production process and identifying the factors contributing to productivity.
- Examined the spatial and temporal variations in the production of oilseed crops
- Examined the magnitude of the technical efficiencies in oilseed production and processing through the Stochastic frontier production approach.
- Measured the Total Factor Productivity and the rate of growth of TFP of oilseed crops viz., castor, sunflower and safflower
- Application of Geographical information System for examining the Physiography, Soils (Slope, Depth, Surface Texture, Surface Stoniness, Calcareousness, Salinity / Sodicity, Drainage, Erosion, AWC and Land Suitability rating) for groundnut in different Agro-Ecological Regions viz., Anantapur, Kurnool and Vizianagaram Districts of Andhra Pradesh under the world bank assisted NATP project . Based on the above analysis, the land suitability ratings were worked out for groundnut crop for the different districts.
- Evaluated the impact of different technological interventions on moisture and nutrient conservation techniques in castor, soybean, sunflower, groundnut and safflower on the farmers’ fields under varied agro-ecological situations in the country.
- Impact assessment of hybrids/varieties of castor hybrids (DCH-177, DCH-519, PCH-111) in Mahbubnagar district of Telangana.
- The decomposition analysis to examine the effect of area and productivity on castor production for the nation as a whole revealed that technology (yield effect ) contributed to 56 % of production and area contributed to 34 per cent during the period 1966-67 to 1976-77 while in the periods 1977-78 to 1987-88 and 1988-89 to 2005-16, the production was primarily driven by area contributing to 76 and 75 per cent of production, respectively. However, during 2006-07 to 2015-16, area and technology (yield effect) contributed to 42 and 40 per cent of the production, respectively
- The contribution of area and technology to the production through decomposition analysis in Gujarat and Rajasthan revealed that production was accounted by more than 50 per cent through area effect (68 and 57 per cent in Gujarat and Rajasthan) during the period 1988-89 to 2005-06. For the period 2006-07 to 2015-16, production was influenced by area in both the states (84 and 70 per cent) in Gujarat and Rajasthan.
- In the major castor growing districts of Gujarat, production was chiefly attributed to area (>50 per cent) in the districts of Banaskanta (62 %), Surendernagar (58%), Kutch (63 %), Gandhinagar (79%) and Jamnagar (58 %) while yield effect (technology) contributed to 80 per cent in Mehsana, 44 per cent in Sabarkanta, 37 per cent in Rajkot and 25 per cent in Vadodara.
- The power of ICT was utilized for transmitting the price information to the farmers in select agro eco regions of the country by digitizing the price information for major APMC's trading oilseeds.
- The spatio temporal information on basic statistics on area, production and yield for the nine annual oilseed crops was digitized and hosted in the IIOR Website for access to the clientele.
- The digitization of information was done for the AICRP reports on IIOR mandated crops including linseed; FLD reports/IIOR annual reports/IIOR foundation day reports. These CD's were distributed to the researchers under the AICRP.
