Abstract

A field experiment was carried out for three consecutive years during 2019-20 to 2021-22 at ICAR Research Complex for Eastern Region, Patna, to assess the best and profitable rice based cropping system through crop diversification for sustainable agriculture. Diversification of wheat with rabi vegetables and inclusion of greengram during summer season in rice-wheat cropping system was studied with different duration of rice. Higher system productivity was recorded in rice-cauliflower-(spinach)-greengram system (34.26 t ha^-1) followed by rice-broccoli-(spring onion)-greengram system (32.47 t ha^-1) which was more than double as compared to system productivity of rice-wheat-greengram system (12.29 t ha^-1). Land use efficiency was recorded maximum in rice-tomato-greengram system (95.34%) and minimum in rice-garden pea-greengram system (82.19%). Growing shorter duration rice in the cropping systems significantly enhanced the system productivity, system production efficiency and income as compared to longer duration rice variety in different cropping systems. Diversification of wheat with rabi vegetables enhanced the gross return, net return and benefit cost ratio irrespective of rice duration. The cropping intensity was also increased by diversifying wheat with cauliflower and broccoli grown after short duration rice (400%), as it provided an opportunity to take a short span crop in the rabi season itself before sowing of greengram during summer season.
