Abstract

Study was conducted to work out the economics of both castor seed and eri cocoon production using ten castor genotypes raised under rainfed condition at Sericulture College campus, Chintamani. Economic analysis revealed that the hybrid castor JI-226 cultivated with recommended practices at 25% defoliation recorded higher gross return (Rs. 38,379/ha), net return (Rs. 27,079) and B:C ratio (2.396:1) both for seed production and eri culture followed by DCS-85 genotype (Rs.38,362/ha, Rs.26,806 and Rs.2.320:1, respectively). Hence, these two castor genotypes are promising and could be used with cost effectiveness for dual purpose of castor seed and eri cocoon production under rainfed conditions.
