Title: PRODUCTION AND ECONOMICS OF IRRIGATED WHEAT (TRITICUM AESTIVUM) AS INFLUENCED BY INTEGRATED NUTRIENT MANAGEMENT
Abstract: An experiment was conducted on wheat during 2011-12 at C.S. Azad University of Agriculture and Technology, Kanpur (U.P.) to evaluate the effect of integrated nutrient management (INM) on crop productivity and economics. Recommended dose of 75% and 50% were integrated with vermicompost, ZnSO 4 and /or biofertilizers. The results revealed that 100% RDF (150 kg N+60 kg P 2 O 5 + 40 kg K 2 O ha -1 ) produced highest grain yield (51.73 q ha -1 ) and straw yield (63.75 qha -1 ) alongwith significantly maximum net return of Rs. 71493 ha -1 . it was followed by the treatment 75% RDF + vermicompost @ 2.5 t ha -1 + ZnSO 4 @ 25 kg ha -1 + seed treatment with Azotobacter and PSB inoculation; 75% RDF + vermicompost @ 2.5 t ha -1 + Azotobacter and PSB; and 75% RDF + vermicomposat @ 2.5 t ha -1 + ZnSO 4 @ 25 kg ha -1 with 49.40, 48.30 and 48.00 qha -1 grain yield; 63.75, 62.40 and 57.63 q ha -1 straw yield and Rs. 66418, 64105 and 59256 ha -1 net return, respectively. All integrated nutrient treatments with 50% RDF yielded lesser and earned lesser net returns than respective integrated nutrient treatments with 75% RDF. Effect of ZnSO 4 and biofertilizers integration was more pronounced with 50% RDF compared to 75% RDF treatments. The control treatment (no fertilizer etc.) produced significantly lowest grain yield (23.25 q ha -1 ), straw yield (31.00 q ha -1 ) and earned minimum of Rs. 18718 ha -1 net return.
