Abstract: Among several management practices that affect soil quality, fertilizer application is of paramount importance for its role in growth and development of the crop. In intensive agriculture with high yielding varieties, crop yields have adverse effect on physical properties of soil such as bulk density, water holding capacity. In spite of increased cost of fertilizer and their adverse effect on soil and environment the best alternative sources for plant nutrients to be explored to meet partial or full requirement of crop. Hence, it is time to pay serious attention to nutrient management. The integrated use of organic manures and inorganic fertilizers can help to maintain optimum crop yields and long term soil productivity.
