Influence of organics and microbial inoculants on growth and nutrient uptake by aerobic rice (Oryza sativa L.)

A field experiment was conducted during kharif season of 2010 at Zonal Agricultural Research Station, V. C. Farm, University of Agricultural Sciences, Bangalore to assess the effect of organics and microbial inoculants on growth of aerobic rice. Application of recommended NPK+Azospirillum brasilense+Bacillus megaterium+ Vermicompost was found better in improving the plant growth parameters viz., plant height (74.31 cm), number of tillers/hill (32.2) and total dry matter production (87.09 g/hill). Maximum uptake of nutrients by the crop was recorded as total nitrogen (78.06 kg/ha), total phosphorus (15.28 kg/ha) and total potassium (101.67 kg/ha) with the supplementation of organics and microbial inoculants to the recommended dosage of inorganic nutrients.
