Studies on non-symbiotic diazotrophic bacterial populations of coastal arable saline soils of India.

The effect of fluctuations of salinity in three different seasons on diazotrophic populations and N(2) fixation in six mono cropped rice field soils of the coastal region of the Gangetic delta of West Bengal, India, was studied. The average pH, ECe, organic carbon and total nitrogen of the soils ranged from 4.99-7.

Characterization and crop production efficiency of diazotrophic bacterial isolates from coastal saline soils.

Use of eco-friendly area specific salt tolerant bioinoculants is better alternatives to chemical fertilizer for sustainable agriculture in coastal saline soils. We isolated diverse groups of diazotrophic bacteria from coastal saline soils of different forest and agricultural lands in the Sundarbans, West Bengal, India, to study their effect on crop productivity in saline soils. Phenotypic, biochemical and molecular identifications of the isolates were performed.
