Comparison of nitrogen use efficiency and its variation among rice cultivars of Manipur, India

Nitrogen use efficiency is considered as one of the most yield limiting factor for the rice production in all the rice growing regions of the world. This experiment was conducted to investigate the variation in nitrogen use efficiency of rice cultivars, the selection of rice cultivars with high nitrogen use efficiency, and the relationships of nitrogen use efficiency with the growth characteristics under non-limiting conditions of factors like water, fertilizer inputs.
