ABSTRACT

At 80 DAS, about 72.03% increase in nitrogen uptake over the control was recorded due to Azotobacterinoculation and it was at par with the addition of 20 kg N ha −1 alone. Nitrogen uptake ranged from 0.73 to 1.66% and 0.93 to 1.85% in straw and grain, respectively. Azotobacter alone and 20 kg Nha −1 were statistically at par in affecting the nitrogen content in straw as well as in grain. Inoculation alone increased about 37.97%, 39.17% and 37.37% phosphorus uptake over the control in the yields of straw grain and total yield, respectively, whereas, potassium uptake was 95.25%. 43.23% and 44.81%. On the basis of results obtained, it was concluded that inoculation of Azotobacter could save about 20 kg fertilizer nitrogen in wheat crop.
