Diversification of rice-wheat cropping system to sustain the productivity and profitability

The field experiments were conducted during 2017-19 at the ICAR-Indian Agricultural Research Institute, New Delhi, India. main aim of study was to find out a suitable cropping system that can replace existing rice-wheat realize higher productivity and profitability. Four systems, viz. rice (Oryza sativa L.) - mustard (Brassica juncea mungbean (Vigna radiata L.), maize (Zea mays mustard-mungbean, potato (Solanum tuberosum onion (Allium cepa fodder maize+ cowpea unguiculata wheat (Triticum aestivum -mungbean, evaluated in randomized complete block design with four replications. Results suggested highest obtained from maize-potato-onion system, recording almost 150% over maize-mustard-mungbean rice-mustard-mungbean systems. next best + -wheat-mungbean, significantly than gross net returns also recorded being all other systems first year, statistically par wheat- second year.
