Effect of N fertilization on yield and yield components of hybrid rice Taifengyou 676
HUANG Xi-hua
Abstract：Take new hybrid rice Taifengyou 676 as a test material,the effect of different N fertilization amounts on the rice yield and yield components was analyzed,the result showed that N fertilization had significant effect on the number of effec-tive spikes per 667 m2 ,number of grains per spike and seed setting rate at the medium-fertility field. The number of effective spikes per 667 m2 and grains per spike,seed setting rate and 1000 grain weight per panicle in the treatment of 12 kg N appli-cation per 667 m2 were even and coordinate,and the yield was the highest.
