摘要

A study was conceptualized to know the farmer's perception about castor based farming vis-a-vis to study the reason for yield gap in traditional and non-traditional tract of Karnataka. It was known from the status report of Directorate of Economics and Statistics, Government of Karnataka 2017-18 that, Karnataka is having an immense potentiality of castor especially in the agro-ecosystems which are often threatened by the vagaries of monsoon. However, a total of9527 ha farm land was occupied by castorwith an average productivity of522 kg/ha as against the national average productivity of 1713 kg/ha. With this, Karnataka could able to contribute 4722 tons of castor to national production. Concurrently, a study was initiated through purposive samplingtechniques to understand the probable reasons for huge gap in yield. The sample unit in traditional castor growing areas consisted of the farm units of Tumkur, Chitradurga, Ramanagar, Hassan, Bengaluru Rural and Kolar Districts where annual rainfall ranges from 550-700 mm whereas non-traditional castor growing tract which receives fairly higher amount of rainfall (850-2000 mm) coupled with time bound irrigation facilities included Mandya, Mysore and Chamarajanagar Districts. From the study, it was observed that an average productivity of castor in traditional and non-traditional tracts seldom exceeds 500 kg/ha except in Chitradurga district (1875 kg/ha). Further, it was also observed that more than 70 and 92 per cent of the farmers in traditional andnon-traditional areas respectively were not been exposed to present day improved cultivars and production technologies, the important factors which discouraged the castor farmers were inadequate rainfall, lack of farm gate procurement, longer duration ofcrop, lack of fodder value, lack of quality seed material in state seed chain with subsidized distributionand biotic stresses like gray-mold and capsule borer infestation etc. There factors are limiting the farmers to adopt improved technologies as a result of which gap in the yield is widening over the years.
