Abstract
The yield of Unkwangbyeo transplanted on May 10 was 596kg/10a in 2010. The rice yield decreased with delaying transplanting date. The head rice rate was 91.9% when transplanted in June 10, and the rate decreased as the transplanting got earlier. In 2011, the yield increased by 5~8% when transplanted on June 10 because of the increase of Ripened grain ratio and 1,000 grain weight. The yield, when transplanted in the distance of $30{\times}13cm$ with 5 plants, was higher than the other treatments. The yield of Oraebyeo, transplanted on June 10, decreased by 6% compared with transplanting on May 25, while the yield, transplanted in the distance of $30{\times}13cm$ with 5 plants, increased by 5% because of the increase in the number/$m^2$ of panicle and grain. The head rice rates of the two varieties increased by 5~7% and the Toyo palatability appeared to get improved when transplanted on June 10 possibly because of the effect of low ripening temperature by 0.9~$1.6^{\circ}C$ with delaying heading date from 9 to 12 days.
