The present study was conducted to evaluate the response of three castor hybrids (PCH 111, GCH 4, Western Maruthi) to varying nitrogen levels (60, 80, 100 and 120 kg N ha-1 ) under rainfed conditions at Agricultural College Farm, Bapatla during kharif, 2017. The growth characters viz., plant height and dry matter accumulation at harvest, days to maturity and SPAD chlorophyll meter reading as well as yield attributing parameters viz., number of capsules per primary spike and test weight as well as bean yield were significantly higher with PCH 111 hybrid and it was closely followed by hybrid GCH 4. Application of 120 kg N ha-1 recorded the highest growth and yield parameters. | Growth and yield of castor hybrids at varying nitrogen levels in Andhra Pradesh India
