Tillage with straw incorporation declines the optimal nitrogen rate for maize production by affecting crop uptake,utility efficiency and soil balance of nitrogen

[Objective]In order to identify the effects of straw return with rotary or plow till and nitrogen(N)application rate on maize grain and straw yield,grain N uptake and N use efficiency(NUE),and soil N balance and to determine the optimal N fertilization rate for maize production under continuous straw incorporation with tillage which is vital for sustainable agriculture in northeastern China.[Method]A four-year(2015-2018)field experiment was conducted to asse…查看全部>>
