Crop Intensification through Relay cropping in Rice Fallows of Assam

The present investigation was undertaken during 2010–11 and 2011–12 at the Kumolia village in Sonitpur district of Assam under the All India Coordinated Research Project for Dryland Agriculture, Assam Agricultural University, Biswanath Chariali to evaluate suitable crop as relay for kharif rice and to find out optimum sowing time for relay crops under rainfed condition. The experiment consisted of 8 treatments namely, T₁: Relay cropping of lathyrus at 15 days after flowering of kharif rice, T₂: Relay cropping of pea at 15 days after flowering of kharif rice:, T₃: Relay cropping of Lentil at 15 days after flowering of kharif rice: T₄: Relay cropping of coriander at 15 days after flowering of kharif rice, T₅: Relay cropping of lathyrus at 25 days after flowering of kharif rice, T₆: Relay cropping of pea at 25 days after flowering of kharif rice, T₇: Relay cropping of lentil at 25 days after flowering of kharif rice and T₈: Relay cropping of coriander at 25 days after flowering of kharif rice. The experiment was conducted on four different farmers’ fields considering as 4 (four) replications in a randomised block design. The pooled data of two years recorded the highest rice equivalent yield of 1335 kg/ha, and net returns of 9639/-with relay cropping of pea at 15 days after flowering of kharif rice (T₂) which was statistically superior over rest of the treatments.
