Located at Raipur to identify efficient cropping systems for Chhattisgarh and. Raipur, rice -be seem was identified to be more efficient and most suited for Chhattisgarh, with highest wheat - grain-equivalent yield (13 479 kg/ha/year), system productivity (36.93 kg/day/ha), stability (0.90), energy production (39.2 × 106 K cal/ ha), land-use efficiency (71%), nutrient use productivity (94.93 kg grain/kg nutrient), net monetary returns (Rs 62 526/ha/ year), profitability (Rs 171.3/ha/day) and benefit: cost ratio (Rs 4.68). Deficit irrigation in some areas may decrease yield but can increase production if land availability is not a constraint. A large potential exists for bridging the yield gap in irrigated areas with consumptive water use between 300 and 475 mm. Of the 222 districts that fall under this category, a 50% reduction in yield gap alone could increase production by 100 million tons without increasing consumptive water use. Supplementary irrigation can increase yield and WP in rain-fed and irrigated areas of 266 and 16 districts with consumptive water use is below 300 mm. Deficit irrigation in irrigated areas of 185 districts with consumptive water use above 475 mm could increase yield, WP and production. Decreasing consumptive water use in irrigated areas with consumptive water use between 425 and 475 mm reduces yield slightly, but if availability of land is not a constraint then the benefits due to water saving and production increases could exceed the cost. This sequence was found specially suited for fodder-scarce animal-based farming situations having good irrigation facilities.
