Abstract: -In India the studies on BGA biofertilizers have been initiated in national centre for conservation and utilization of blue green algae (NCCUBGA) at Indian agriculture research institute (IARI) New Delhi in India the pioneer works in this field was done by De (1939) Singh(1691) Venkatraman (1961) Venketraman and Goyal (1987).

Blue green algal biofertilzer plays a vital role in providing biologically fixed nitrogen, carbon and improving the physical and chemical properties of soil, there are several reports on use and recommendation of BGA biofertilizers in paddy crops, very few reports are related to other crops.
The field experiments were conducted on farms field at Nimgaon paga village, of Sangamner tahasil dist Ahmednagar. The Sangamner tahsil is located in northern part of the Ahmednagar district of Mharashtra state .The tahsil lies between 18036 to 1901 N latitude and 7401 W to 74056 W longitude.The area drained by Pravara river.

The present paper include that during last few decades in above locality, due to extensive use of chemical fertilizers the productivity of soil is reduced. To over come this problem it was decided to study the roll of BGA bioferitilizers in Brinjal crops .the role of BGA biofertilizers was studied with observation in BGA alone, BGA +FYM and chemical fertilizers treatment as compared to control. Use of BGA +FYM biofertilizer to brinjal crop in field is beneficial for fruit yield than BGA alone or chemical fertilizers.
