Microbial Diversity for Biofertilizers
- Genetic diversity of rhizobia of twenty major legumes under progress, including from arid and hyper-arid zone. Characterization for 16S sRNA, nif and nod genes showed high diversity in soybean rhizobia which belonged to two groups – Bradyrhizobium japonicum and Rhizobium radiobacter.
- Rhizobium isolates of legumes from `Tal’ lands of Bihar and endophytic rhizobia of stem nodules characterized. Studies on rhizobia with ability to control plant diseases in progress. Consortia of rhizobia and plant growth promoting rhizobacteria (PGPR) for black gram in Andhra Pradesh increased yields by 30%.
- Proteomics of rhizobial isolates of legumes in Jharkhand to characterize genes conferring acid tolerance in progress.
- Fluorescent pseudomonads inoculum for control of stem rot of groundnut improved pod yields in Gujarat by 7-20%.
- Arbuscular mycorrhizal fungi (AMF) inoculum for upland rice in Jharkhand improved rice yields by 7-20%.
- Actinomycetes strains isolated from arid and semi-arid soils improved maize yields in Vertisols of M.P., by 15-30%. In chickpea, yield increases ranged from 20-35%. Formulations of rhizobia and actinomycetes gave high yield increase in chickpea (65%) over uninoculated control.
- Field demonstrations of PGPR Bacillus licheniformis controlled white root rot disease of apples and increased yields by 40% in Himachal Pradesh. Work on PGPR for improving yields of cherry, apricot, seabuckthorn and medicinal plants in progress. Biofertilizer package for cauliflower increased yields by 25-30% in Himachal Pradesh and saved 25% NP fertilizers.
- Bioinoculation of vegetables- knol khol and pointed gourd in acid soil in Odisha increased yields by 8-12% and 10-15% respectively and increased NPKS uptake efficiency significantly. In bitter gourd yield increased by 12%, along with increase in vitamin C by 8% and protein content by 11%. There was extra recovery of NPKS of 11, 20, 13 and 3% resepctively.
- In Jute-rice-green gram system in Odisha, jute yield increased by 19% due to biofertilization over soil test dose, in rice by 8% and in green gram by 12%. NPK recovery increased from 62.0 to 74.0% in STD + BF (extra nutrient uptake of 42 kg/ha). In Jute in Assam, application of biofertilizers decreased the consumption of chemical fertilizers by 50%.
