Abstract

A field experiment was conducted to evaltuate the effect of integrated nutrient management on availability of cationic micronutrients in soil, crop response and economic feasibility of their use in tomato-onion cropping system. Application of organic manures in conjunction with inorganic fertilizers significantly improved the availability of Fe, Cu, Mn and Zn in soil. The availability of Fe, Cu, Mn and Zn increased with increase in the level of organic manures application. Significant and positive correlation existed between OC and available cationic micronutrients like iron (r=0.830), copper (r=0.795), manganese (r=0.877) and zinc (r=0.816). Based on the results of this study, it could be concluded that the combined use of organic manures with inorganic fertilizers is suitable for obtaining optimum yields
