Abstract
A study has been made on growth and technological changes in major oilseed crops of Karnataka. For this study the secondary data on area, production and productivity of major oilseed crops have been collected from the Directorate of Economics and Statistics Bangalore for past 30 years (from 1985-86 to 2014-15). Linear and exponential models were fitted to find linear and compound growth rate of major oilseed crops separately for period I (1985-1999), Period II (2000-2015) and for Combine period. The results indicated that, except soybean, all other oilseed crops had negatively significant growth rate.Non-significant growth was observed in case of sunflower and rapeseed-mustard for its area and production during combined period. In case of productivity, LGR and CGR were found to be positively significant for soybean, sunflower, safflower, niger, rapeseed-mustard, sesame and linseed, except groundnut and castor. Cobb-Douglas production function was used to know any technological changes in production of oilseed crops for period I period II and for pooled period. Technological change was determined by significant structural break through Chow test. Except sesame and rapeseed-mustard no other oilseed crops under the study shown technological changes in pooled period. This suggest that there is need to improve the technology in production of oilseed crops in Karnataka State.
