Abstract:In order to explore the effects of different nitrogen(N) fertilizer management on the yield and quality of hybrid indica rice varieties with different taste value, we used the hybrid indica rice varieties Guangyou 847(high-quality taste) and F You 498(high-yield and low taste) as materials, and applied of six N fertilizer conditions, N application 120 kg/hm2 and 150 kg/hm2 with three fertilizer ratios of the base fertilizer, tiller fertilizer and spike fertilizer 4∶4∶2, 3∶3∶4, 2∶2∶6 and one control with no N treatment. The results showed that varieties and N fertilizer management had significant or extremely significant effects on the yield, rice processing and appearance quality, RVA profile, and cooking and eating quality of indica hybrid rice with different tastes. The effects of varieties on milled rice rate, head rice rate, length width ratio, chalkiness and chalky grain rate were favor of the N fertilizer nitrogen management. The effect of nitrogen management on rice yield and taste value was more obvious than that of varieties. The yield components could be further optimized to promote dry matter accumulation in the rice population from heading to maturity stage and improve rice cooking taste value. The condition of 150 kg/hm2 N rate and 3∶3∶4 fertilizer ratio could significantly increase the rice yield of various hybrid indica rice varieties and effectively improve the taste quality of rice.
