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.
