Abstract

To test the effects of application of ecological fertilizer NutriSmartTM combined with chemical fertilizer(NSCF)on rice yield and nitrogen use efficiency,a field experiment was carried out in Hangzhou,China.Under NSCF treatments a gently increase in the number of tillers and a higher percentage of effective tillers were noted while under the control(chemical fertilizers only)treatment,the number of tillers increased rapidly with more unproductive tillers.The grain yields in NSCF treatments increased significantly by 6.40% to 9.53%(in Shanyou 63)and 6.70% to 9.52%(in Xiushui 63)compared to the control,with no significant differences in grain yields among NSCF treatments.Agronomic nitrogen use efficiency(ANUE,being difference in grain yields between nitrogen and non-nitrogen treated plots divided by N applied)and fertilizer nitrogen recovery efficiency(NUE,being difference in N uptakes between nitrogen and non-nitrogen treated plots divided by N applied)in each NSCF treatment of Shanyou 63 and Xiushui 63 were significantly higher than those of the control.It could be concluded that rational application NSCF contributed to an early vigorous growth of rice,a sufficient supply of nutrients during the middle-late growth period,an increase in green leaf area during the grain filling period,accelerating the translocation of the photosynthates to panicles and grains,and finally enhancing the total dry matter production and the grain yield.Meanwhile,rational application NSCF could reduce the application of N fertilizer on rice and improve the nitrogen use efficiency.
