The recent concept of integrated nutrient supply involving organic, inorganic and bio -fertilizers has developed to meet the growing need for nutrients under intensive cultivation. In integrated plant nutrition supply system, the basic goal is to maintain or possibly improve the soil fertility and plant nutrient supply to an optimum level for sustaining the desired crop productivity through optimization of the benefits from all possible sources of plant nutrients in an integrated manner. The continuous increase in the use of inorganic fertilizers results in decrease in soil fertility. The plant nutrients need to be applied through natural organic sources for profitable fruit production. This has become important to use available chemical fertilizers efficiently through suitable application methods and to follow integrated nutrient management practices by combining inorganic fertilizers with organics, which not only improve the fruit quality and soil health but also remain for longer period in soil to make it healthy and in productive Condition.Therefore this book aims to increase the yield and quality of guava with the adoption of integrated nutrient management.
