Optimum sowing time with improved genotypes is one of the most important agronomic factor and non- monetary input which play an important role to exploit fully the genetic potentiality of a castor crop. Experiments were conducted for three consecutive years (2013-14, 2014-15 and 2015-16) during the Kharif season at the Zonal Agricultural and Horticultural Research Station, (130 57’ 32” N, 700 37’ 38” E, 606 MSL), University of Agricultural and Horticultural Sciences, Shivamogga, India, to find out the optimum sowing schedule and genotype to maximize the castor productivity. The pooled data of three years indicates that the sowing during 2nd fortnight of August has recorded significantly higher yield (2407 kg ha-1) compared to the crop sown during the second fortnight of September (1946 kg ha-1) or October (1259 kg ha-1) or November (840 kg ha-1). Among the genotypes tested GCH-177 has recorded higher grain yield (1805 kg ha-1) compared to YRCH-1 (1627 kg ha-1), DCS-107 (1647 kg ha-1) and GCH-7 (973 kg ha-1). Extended dates of sowing of castor on the 2nd fortnight of August increased the seed yield by 19 and 65%, respectively. Economics analysis showed that sowing during 2nd fortnight of August and hybrid DCH-177 recorded higher gross return (Rs 86,669 ha-1 and Rs 64986 ha-1), net return (Rs 62,588 ha-1 and Rs 40905 ha-1) and B:C ratio(3.6 and 2.7) respectively.
