Pant University of Agriculture and Technology, Pantnagar, Uttarakhand (India) during year 2014-2015 to intensify and diversify ricewheat cropping system by inclusion of legumes, cash crops, fodder and vegetables under different land configuration for developing need based bio-intensive cropping system for small land holders of irrigated tarai region of Uttrarakhand. Among the tested diversification options, rice (DSR) - Potato -Cowpea (Grain) was most productive with highest system productivity (30.91 t/ha) followed by Maize + Cowpea+ Sesbania – Vegetable pea + Toria – Groundnut + Mentha (21.35 t/ha) under broad bed system, both being significantly higher than rice-wheat system. These were more efficient in productivity as compared to rice – wheat system (9.67 t/ha) and Rice (TPR) - Vegetable pea – Summer Rice (TPR) (19.78 t/ha) which is most widely adopted cropping pattern of irrigated tarai region. Therefore, diversification and land configuration changes helped not only in obtaining better system productivity and profitability but also better efficiency in terms of water and energy savings.Not Availabl
