Abstract
Effects of different application rates of nitrogen on hybrid rice Liangyoupeijiu was studied, in comparison with Shanyou 63 under field conditions. The results show that the amount of N-uptake, the biomass accumulation and the N-requirement per 100 kg grain increased with the N-application rate. The yield and N-recovery increased with N-application rate at first, amounted to highest level at moderate N level, then decreased dramatically at high N level. The yield, amount of N-uptake, biomass accumulation and N-recovery of the variety Liangyoupeijiu are higher than those of Shanyou 63 at the same N level. The N-requirement per 100 kg grain is about 2.0-2.2 kg and the N-recovery is around 40% at the yield level from 9 000 to 10 500 kg·ha -1. The nutrition quality, milling quality, steaming and taste quality become better with the N-application rate, while the apparent features become worse. The difference in yield and quality between the varieties is significant. Comparing to the variety Shanyou 63, the yield of the variety Liangyoupeijiu is higher and the quality is better.
