Abstract
The responses to the application of Azolla microphylla dry matter for nitrogen use efficiency for biomass (NUE) and nitrogen use efficiency for grain yield (NUEg) were investigated in two Japonica rice varieties. NUE and NUEg reduced with higher rated of Azolla application. The highest values were recorded at the rate of 37.5 kg N ha-1, and the lowest values were recorded at 187.5 kg N ha-1. DOA1 was higher than DOA2 for NUE, but they were similar for NUEg. Grain yields increased with higher rates of Azolla application. Grain yield was the lowest at the rate of 37.5 kg N ha-1 and the highest at the rate of 187.5 kg N ha-1. DOA1 and DOA2 which were similar for grain yield.
