ABSTRACT
A field experiment was conducted to study the maximization of wheat yield through integrated nutrient management in wheat and residual effect of preceding kharif crops on wheat during 2007-08 and 2008-09 at Anand. Total twenty four treatments consisted of three preceding crops (maize, soybean and greengram) in main plots and eight treatments of INM in which two levels of bio-organics (0 and 2.0 t Vermicompost/ha), two nitrogen levels (60 and 120 kg N/ha) and two levels of phosphorus (0 and 40 kg P2O5/ha) in sub-plots and experiment was laid out in split plot design with three replications. Among the different wheat-based cropping system, the maximum wheat grain equivalent yield (WGEY) was recorded with soybean- wheat being 20.3 and 43.9 % higher than that greengram - wheat and maize - wheat cropping system, respectively. Nutrient management in wheat crop produced the highest grain and straw yields of wheat under bio-organic treatment, which was 4.9 % more over control. Application of 120 kg N/ha recorded significantly higher grain yield of wheat and net realization than 60 kg N/ha treatment. In case of phosphorus levels the application of 40 kg P2O5/ha gave remarkably the highest grain yield and net return. Growing soybean and greengram as the preceding crop resulted significantly higher grain and straw yields of wheat than preceding maize crop. The maximum net return, WEGY, production efficiency and land use efficiency were obtained with Soybean-Wheat cropping system and wheat crop fertilized with 120 kg N and 40 kg P2O5/ha.
