    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.

    Effects of chicken manure and chemical fertilizer on Growth and Yield of Japonica Rice

    Organic and inorganic nitrogen fertilizers are normally used in Indica rice (Oryza sativa L.) production system, but information on the effects of chicken manure on Japonica rice is limited. The effects of chicken manure and chemical fertilizers on growth and yield of Japonica rice were determined. Rice varieties were significantly different for most traits including plant height, crop growth rate (CGR), biomass, percentage of filled and unfilled grain, number of grains per spikelet and harvest index (HI), except for grain yield. Chemical fertilizer had the highest grain yield followed by chicken manure, non-treated control and chemical fertilizer together with chicken manure, respectively. The interaction effects between fertilizer treatment and rice variety were not significant for all characters. These rice varieties seemed to better respond to chemical fertilizer than chicken manure treatments.
