Effect of Biofertilizer, Manures and Chemical Fertilizers on Guava

Guava is grown all over the tropical and subtropical regions and in all parts of India. It is also called as 'Apple of the Tropics'. Low productivity of guava may be due to less adoption of improved crop management technology in respect of planting system, nutrition, plant protection and irrigation etc. Among several other factors, probably nutrition is a key factor affecting the productivity of fruit trees. As guava tree removes large amount of nutrients from soil, balanced fertilization seems to be an important factor governing the productivity of guava trees. The recent concept of integrated nutrient supply involving 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. Guava is very hardy to soil and agro-climatic conditions and gives good response to manuring in terms of increasing fruit production and quality.
