Title: Fertilizer efficiency on super rice Yongyou No. 6 used as late rice cultivar
Abstract: This paper studied the fertilizer efficiencies of N,P and K on super rice Yongyou No.6 when used it as late rice cultivar.The results showed that,N fertilizer showed the best yield-increasing effect,then K fertilizer.The N,P2O5 and K2O fertilization amounts for the maximum grain yield were 10.4 kg /667 m2(156 kg/hm2),1.4 kg/667 m2(21 kg/hm2),9.0 kg /667 m2(135 kg/hm2) respectively and could reach 482.4 kg/667 m2(7 236 kg/hm2) rice grain yield,and the fertilizer amounts for the maximum economic benefit were N 7.2 kg /667 m2(108 kg/hm2),P2O5 0.9 kg /667 m2(13.5 kg/ hm2) and K2O 9.0 kg /667 m2(135 kg/hm2) respectively and could get economical benefit by 1 061.5 RMB Yuan/667 m2(15 922.5 RMB Yuan/hm2).
