The Yield levels of castor in rainfed environment in farmer's field were very low( + 180-250 kg/ha) and widely fluctuate due to vagaries of rainfall, use of local seed and poor management. To achieve stability of castor in farmer's fields the farm Science Centre of 'CRIDA' organized skill oriented trainings and also demonstration after assessing tha gaps in production of castor for the farmers in Ranga Reddy district. The results of crop cutting sirvey in both trainess and non-trainess fields indicated that use of improved seed (GCH-4) along on an average increased the seed yield by 41 per cent compared to the local 'Aruna ': while top dressing of 20kg N/ha through urea recorded additional income of Rs. 1150/ha compared to basal application of 10-30-0 over years. Under moisture stress situations, 20Kh N/ha as top dressing along with basal application of 10-30-0 NPK kg/ha was found optimum. sowing of castor in second fortnight of june recorded the highest bean yields of castor. Delayed sowing of castor by 15,30 and 45days after first fortnight of june reduced yields by 9,30 and 40 per cent respectively control of weeds with two harrowings recordrd additional cost benefit ratio of 11.5 as against the recommended practies of two blade harrowing following by one hand weeding over the years. use of improved seed, recommended dose of fertilizer and control of semilooper by the farmers increased the bean yield of castor by 95 per cent compared to the traditional practices adopted by the farmer.
