An experiment was conducted to know the effects of crab shell, sericite ore, and charcoal powders on the growth, yield, and grain quality of rice. After application of 110-40-57 kg/ha of $N-P_2O_5-K_2O$, 3,000 kg/ha of crab shell and charcoal powders and 5,000 kg/ha of sericite ore powder were applied and incorporated into soil before transplanting of rice seedlings. The number of tillers and panicles, leaf area index at heading stage, N concentration of plants, and protein content and chalkiness of rice grains were increased with the application of crab shell powder, while the percentage of ripened stains and head rice and Toyo taste value were decreased. The yield of milled rice and other grain appearance and chemical and physical properties of rice grains were not affected by the application of crab shell powder. The sericite ore and charcoal powders increased protein content decreased Toyo taste value, but did not affect on the growth, yield and yield components and other grain qualities.
