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.
