 ABSTRACT

Biofertilizer is a relatively safer, environmental friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Rhizobium, a nitrogen fixing bacteria is found both as free living in soil or in associative form within the root nodules of host legumes. Nine different colonies of Rhizobium spp. were isolated from which two isolates isolate 7 and 9 were finally selected on the basis of their better growth on yeast extract mannitol agar for their biochemical characterization and study its efficacy on rice growth promotion. The results has successfully demonstrated the effectiveness of isolated rhizobial strains from rice field with multiple beneficial characteristics on vigor of rice seedlings under controlled condition. The result proved to be a vital information in the development of a liquid biofertilizer for rice.

Key words: Rhizobium, Rice, Isolates, YEMA
