Abstract
This study was conducted to evaluate the effects of silicate fertilizer, soil addition and iron powder on yield and quality of rice. High density plot, cropping pattern of rice showed relatively superior values for all the yield components and yield with 83.2cm in culm length, 21.9cm in panicle length, 8.8 in number of panicles, 65.7% in percentage of productive tillers, 23.15g in weight of 1,000 grain of brown rice, 658.7kg/10a in rough rice yield and 544.7kg/10a in brown rice yield. The results indicate that plot of high density, cropping pattern shows different adaptabilities to a particular cropping pattern and high density plot seems to be the most suitable culture method of rice for high yielding.
벼 재배기술의 개선방향을 모색코자 객토 철분 및 규산질 비료를 첨가하여 다수확 재배 실험하였던바 보통재배구에 비하여 간장, 수장은 길고 수수도 많았으며 현미천입증도 무거워서 현미수량은 544.7kg/10a로 보통재배구의 431.8kg/10a보다 26% 증수였다.
