An experiment was conducted to study the effect of crop diversification and intensification in ricewheat cropping system on production potential, profitability and energy use efficiency on sandy clay loam soil at Agricultural Research farm, B.H.U., Varanasi, U.P. The treatments comprising of 14 crop sequences were arranged in a randomized block design under three replications. The overall productivity of the system in terms of RGEY was noticed significantly highest in rice-potato-black gram (312.73 q ha-1yr-1) over rest of the cropping sequence except rice-maize (cob) + veg. Pea (1:2) – green gram cropping sequence (301.91 q ha-1yr-1). The net energy return was maximum under ricemaize (cob) + veg. Pea (1:2) –green gram cropping sequence (163.78 ‘000 MJ ha-1yr-1) followed by rice-potato-black gram. Energy output: input ratio was also highest in rice-maize (cob) + veg. Pea (1:2) – green gram cropping sequence (4.01). Early pigeon pea – wheat-maize (fodder) cropping sequence registered maximum land utilization efficiency (97.81%) followed by rice-rapeseed-onion cropping sequence (90.68%) and the value was lowest in rice-wheat cropping sequence (68.49%).

Abstract


An experiment was conducted to study the effect of crop diversification and intensification in ricewheat cropping system on production potential, profitability and energy use efficiency on sandy clay loam soil at Agricultural Research farm, B.H.U., Varanasi, U.P. The treatments comprising of 14 crop sequences were arranged in a randomized block design under three replications. The overall productivity of the system in terms of RGEY was noticed significantly highest in rice-potato-black gram (312.73 q ha-1yr-1) over rest of the cropping sequence except rice-maize (cob) + veg. Pea (1:2) – green gram cropping sequence (301.91 q ha-1yr-1). The net energy return was maximum under ricemaize (cob) + veg. Pea (1:2) –green gram cropping sequence (163.78 ‘000 MJ ha-1yr-1) followed by rice-potato-black gram. Energy output: input ratio was also highest in rice-maize (cob) + veg. Pea (1:2) – green gram cropping sequence (4.01). Early pigeon pea – wheat-maize (fodder) cropping sequence registered maximum land utilization efficiency (97.81%) followed by rice-rapeseed-onion cropping sequence (90.68%) and the value was lowest in rice-wheat cropping sequence (68.49%).
