Effects of azotobacter application either individually or in combination with the use of organic and chemical fertilizers on the growth and yield of transplant aman rice and nutrient status of post-harvest soil were evaluated. Increased growth in terms of leaf area index and tiller number/plant was recorded from Azotobacter application both individually and in combination with the use of organic and chemical fertilizers. Considering both grain and straw yields, Azotobacter exhibited significant influence along with all levels of organic and chemical fertilizers. But overall best performance regarding growth and yield was observed from Azotobacter application along with the use of three-fourths of the recommended dose of chemical fertilizers. Analysis of post-harvest soil showed that Azotobacter along with the use of three-fourths of the recommended dose of chemical fertilizers performed the best in maintaining organic matter and available P status in soil.
