Effect of Azotobacter on Rice Crop

Abstract

                                Azotobacter treatment to seed seedling and soil helped good initial plant growth and better tillering of paddy. When applied in combination with 75 per cent of the re- commended dose of fertilizer nitrogen, the Azotobater could compensate 25 per cent of fertilizer N and bring out the same yield of paddy crop as that of cent per cent fertilizer N without Azotobacter treatment, thereby reducing the cost of cultivation. Azotobacter treatment with cent per cent of the recommended dose of fertilizer N resulted in the increase of grain yield slightly. Azotobacter treatment to paddy during January-May season brought out the beneficial effects convincingly than during the August-December season.
