Abstract: To get more yield farmers tend to use excessive chemical fertilizers, while current energy crisis prevailing higher prices and lack of proper supply system of fertilizers and deterioration of soil health calls for more efficient nutrient management using conjunctive use of organic manure, inorganic fertilizers and biofertilizer to sustain yield levels and agro-eco-system. Therefore, a thrice replicated 2 year field trial was conducted during 2010 and 2011 by using F test. The results revealed that combination of 100% NPK + 5 t FYM+ Azotobactor + PSB recoded higher mean growth attributes viz.,plant height (201.25 cm), dry weight/plant (267.25 g), LAI at 60 DAS (4.2), yield attributing component and yield viz., cob/plants (1.1), number of grain/cob (541.2) and test weight (245.05 g), grain yield (53.15 q/ha), quality parameters viz., protein content (8.38%) and protein yield (445.4kg/ha), total nutrients uptake and economics viz.,net return/ha (Rs 36073.5), B:C ratio (2.86), production efficiency (59.1 kg/day/ha) and economic efficiency (400.8 Rs/day/ha), besides achieved maximum nitrogen used efficiency as compared to rest of its counterparts Thus, study suggests that maize can be successfully grown under Indo-Gangetic plain zone on 100% NPK + 5 t FYM+ Azotobactor + PSB and harvest maximum productivity and profitability besides, improving used efficiency of nitrogen.
