ABSTRACT
Biofertilizers are natural and organic products. They help to provide and keep the soil with all the minerals and microorganisms required for plant growth. Their application is easy, cost effective and does not cause any pollution problem. In India, biofertilizers constitute the best renewable source of nutrient supply to plants and as supplement to chemical fertilizers and organic manures. The comparative effects on FYM, Inorganic fertilizers and Biofertilizers on growth ofblack gram (Vigna mungo L.) were studied.The thirteen treatements were studied under this experiments. The highest growth was recorded in combined application of biofertilizers alone. The inorganic fertilizers and organic manures are gradually increased in growth, and biochemical contents.Hence the use of biofertilizers should be encouraged.
