Title: Proper Nitrogen Application Level for Improving the Rice Quality in Honam Plain Area
Abstract: This study was carried out to elucidate the proper nitrogen application level considering rice quality in Honam plain area from 2002 to 2004 at the paddy field of Honam Agricultural Research Institute. The rice cultivars tested were Samcheonbyeo (Early maturing one), Hwaseongbyeo (Medium maturing one) and Nampyeongbyeo (Mid-late maturing one). The results are summarized as follows: The higher amount of nitrogen application resulted in greater number of panicle and grain in per unit area, but the rate of ripening and the 1,000-grain weight of brown rice decreased. The protein contents showed a tendency of increase with higher nitrogen level. The head rice yield increased by the higher nitrogen application up to 7 kg/10a for Samcheonbyeo and Hwaseongbyeo, and 9 kg/10a for Nampyeongbyeo respectively. The appropriate nitrogen application amounts, with respect to the yield of head rice, the rate of ripening and the quality of rice were found to be in range of 7 to 9 kg/10a.
