Guava is one of the most important fruit and
is a good source of Vitamin C (260-300mg/100g of pulp) and highest fiber
content of 6.9%. Presently,
the productivity of guava is smaller than productive potential primarily due to
traditional system of wider planting and secondarily due to poor fertilizer management practices. Chemical fertilizers are extensively used in guava crops which caused various threats to environmental, human, and soil
health over a period of time. However, soil microorganisms play a significant
role in regulating the dynamics of organic matter decomposition and the
availability of plant nutrients. Hence, the application of biofertilizers is
becoming popular these days as an important alternative to chemical
fertilizers. On the basis of the application of bio-fertilizers, it can
be broadly classified as:
1. Nitrogenous
(N) bio-fertilizer
2. Phosphatic
(P) bio-fertilizer
3. Potash (K)
