Impact of Fertilizer Doses with Soil Conditioners under Maize–Wheat Sequential Cropping

An experiments was carried out in tow consecutive year of Kharif and Rabi season of 2003-04 and 2004-05 at Agriculture Research Farm of Shri Durga Ji Post Graduate College Chandeshwar Azamgarh under afflicted Veer Bahadur Singh Purvanchal University, Jaunpur (UP) with a view to find out the production potential of maize-wheat cropping system under different fertilizer doses with soil conditions. The results showed that the wheat equivalent yield was received maximum of 80.01and 79.71q/ha with FYM application while in gypsum reduced 74.32 and 76.26q/ha and minimum equivalent yield of 71.79 and 73.23q/ha was recorded in control plot during first and second years, respectively. On the mean basis gross income of Rs. 63159 and Rs. 63878 /ha and net profit of Rs. 28246 and Rs. 29017/ha were significantly more obtained with FYM from maize-wheat system during both year, respectively while, gypsum gave gross income of Rs. 59199 and 60653/ha and net profit Rs. 26479 and Rs. 27933/ha during respective years. The percentage increment of FYM in soil conditioner over control was 10.77% and 9.18% net profit in first and second years respectively. In case of fertilizer, significantly maximum equivalent yield of 80.85 and 82.07 q/ha was obtained at 125% fertilizer during first and second year, respectively. The highest gross income of Rs. 63798 and Rs. 64854/ha was achieved with 125% fertilizer while maximum net profit of Rs. 28901 and Rs. 29682/ha was obtained with 100% RDF during first and second year. The increment percentage in net profit of 22.05% and 19.91% compared to 50% RDF during both the years, respectively. Therefore, application of FYM @ 5ton/ha along with 100% RDF proved to be most economic combination of the system. Keyword: Soil Conditioners, Fertilizer Doses, Maize, Wheat, Crop rotation
