Abstract
A field experiment was conducted to study the effect of nutrient management on yield and yield components of rice by using four cultivars derived from Yunnan and Zhejiang in the recent years.The result indicated that:(i)the basal fertilizer and tiller fertilizer had significant effect on yield,effective panicles,number of grains on primary rachis-branch per panicle,number of grains on secondary rachis-branch per panicle,number of grains per panicle.The productive tiller percentage,spike length,seed setting rate,1000-grain weight,flag leaf length and width,second leaf length and width,have a significant enhance by panicle fertilizer.(ii) the significant effects of different fertilizer time were observed on nutrient management of different fertilizer time in hybrid than that in conventional rice.Nutrient management at late stage of rice growth significantly increased the yield of hybrid.
