A study on potential of Rhizobium spp as bio fertilizers in sustainable agriculture

摘要

In this project Rhizobium bacteria was isolated from the root nodules of "Mimosa pudica" and used as a microbial culture for the production of biofertilizers. The biofertilizers were prepared using the Rhizobium with two different carriers charcoal and seed cake powder of "Pongamia pinnata". To study the effect of biofertilizers, soil treatment was carried out and plants were cultivated in it. At regular intervals certain parameters of plants such as height, number of flowers, and number of buds weretabulated. Other parameters such as soil pH, nitrogen and phosphorous content in the soil were tested before the addition of biofertilizer and after the completion of experiment. Results of each carrier and without carrier has been compared with different parameters and plants.
