Abstract

In this study the influence of combined use of organic and inorganic nitrogen (N) sources along with the beneficial micro-organisms on grain N uptake, N use efficiency and N utilization efficiency in maize was evaluated. Organic fertilizer (FYM) and inorganic N source (synthetic fertilizer) was applied in ratio viz. (0:100, 25:75, 50:50, 75:25 and 100:0) with and without beneficial micro-organism. Different levels viz. 100, 150 and 200 kg ha−1 of N was used to accelerate the efficiency of N. Results showed that combination of FYM and inorganic N (50:5) along with the application of beneficial micro-organism significantly increased the total N uptake, N utilization efficiency, highest stover grain and grain protein. However, maximum N uptake and protein contents were recorded with application of 150 kg N ha−1. Application of N (100 kg ha−1) gave the highest N-use efficiency and N utilization efficiency. In conclusion, N application level of 100 kg N ha−1, beneficial micro-organism and 50:50 ratio of inorganic and organic N was proved better in enhancing N-use efficiency and grain quality of maize.
