Integrated use of organic manures and inorganic fertilizers was studied for crop response in an experiment based on tomato-onion cropping system. Application of organic manures with inorganic fertilizers significantly improved the availability of N, P, and K in soil. The availability of major nutrients in soil increased with increase in level of organic manures application and with no fertilizer registered maximum but on par with 50 and 75 per cent manure levels while the 25 per cent level of organic manure recorded minimum. Based on the results of this study it could be concluded that the combined use of organic manures and inorganic fertilizers is suitable for sustaining yield and maintaining soil health.
