Field Efficiency

Organic farming is gaining popularity where bio-inoculants could play a key role in promoting the growth of plants. The liquid biofertilizers concept is new to farmers and developed recently. Lots of liquid biofertilizers formulations and field efficiency were shown in the past by various researchers, but the plant growth promoting (PGP) efficiency of the liquid biofertilizers isolates were not reported till date. In the present work 6 different commercially available liquid biofertilizers were used to isolate the organism. These isolated cultures were used to study their PGP efficiency with respect to phosphate solubilization and production of EPS, IAA, siderophore, ammonia, chitinase, ACC-deaminase and HCN. The phosphate solubilization was shown up to 303 g/ml by APS isolate. EPS production was shown by using different C sources and production up to 24 g/l was shown by studied isolated. Most of the organisms studied were able to produce IAA and highest production was shown up to 20 g/ml. More than 65% studied isolates showed siderophore and ACC-deaminase production. The present study shows that the commercial liquid biofertilizer isolates possess multiple traits of plant growth promotion.
