Three castor hybrids were YRCH 1, DCH 519 and DCH 177, which were sown by following all recommended package of practices followed as per TNAU recommendation. The study revealed that DCH 519 recorded more number of effective spikes per plant (38.20), number of capsules per spike (57.4), very less incidence of leaf hopper (2.20 %), lesser incidence of botrytis (2.6 %), higher seed yield (1311.6 kg/ha) as compared to YRCH 1 and DCH 177 hybrids. The least seed yield (1037 kg/ha) and higher incidence of leaf hopper (13.6 %) and botrytis (7.8 %) were observed in DCH 177 hybrid. Gross and net returns were Rs. 65580/- and Rs. 42010/ha, respectively by cultivating DCH 519 as against Rs. 64850/- and Rs. 41230/ha in the YRCH 1 hybrid. Farmers were satisfied with DCH 519 and YRCH 1 hybrids, as crop did not suffer from botrytis disease. Castor DCH 519 and YRCH 1 hybrids would be a better option for pure crop in kharif season in north western zone of Tamil Nadu. Download Full Paper
