Agricultural Microbiology Biofertilizer Project


Research on Agriculturally Important Beneficial Microorganisms was started at GAU, now AAU as Biofertilizer research in 1979 with special emphasis on Azolla which was later on strengthened with inception of NARP in 1983 with major thrust to identify and isolate efficient native microbial cultures which augment atmospheric Nitrogen or solubilize phosphorous, suitable for different agro-climatic conditions of Gujarat State. Achievements on research carried out by faculty members by different projects and post graduate students research on Agriculturally Beneficial Microorganisms are considered and compiled.
