TECHNOLOGICAL CHANGE AND ITS IMPACT ON SERICULTURE DEVELOPMENT IN KARNATAKA

摘要

The release of production oriented technologies in sericulture evolved over the last three decades have hastened the productivity in sericulture. The technological break through in sericulture is a vital component of development of sericulture in India, for gaining self sufficiency in production besides improving the quality of silk production. A rise in the total output under 'new' technology over the 'old' with the use of same level of inputs can be attributed to the technical change. This change in total output due to technology is measured by changes in scale (intercept) and slope (elasticities) parameters. A study was conducted to ascertain the structural break in production with the introduction of new technologies in silk cocoon production. It was found that the silk cocoon production in 'new technology farms' was 33.09 per cent more than 'old technology farms'. With regard to input use the 'new technology farms' tended to use 34.32 per cent more chemical fertilizers, 76.92 per cent more farm yard manure, 17.72 per cent more number of DFLs and 15.38 per cent more disinfectants and materials in silk cocoon production. Labour was one of the components used at a lower rate than 'old technology farms' at -6.56 per cent. From the analysis of thestructural break through in silk cocoon production, it revealed that the contribution from the new technology was significant. The total gain in production due to the shift from 'old technology' to 'new technology' was found to be 28.58 per cent, whichwas mainly contributed due to the difference in the levels of input use.
