| Abstract: | The field culture was conducted to study the effect of water and nitrogen cooperation on grain yield and water use efficiency in winter wheat.The results showed that the effect of N fertilizer was inhibited seriously by water stress,only with the condition of water and nitrogen coordination,it was developed abundantly.There by,N fertilizer could not only increase winter wheat yields but also improve water use efficiency in winter wheat. |

| Keywords: | winter wheat grain yield water use efficiency water and nitrogen effect |
