The purpose of this study was to analyze dry matter, yield and quality changes of character in five spring maize （Zea mays L.） cultivars, Nongdal08, Sidanl9, Longdan26, Fenghe10 and Dongnong250 under N input （N. __and N stress （NO） conditions. The results showed that with N0, N. _can significantly improved the dry matter production of maize, grain yield, grain and crude protein content of starch content, but significant differences existed between different varieties. Nongda108 and Sidan19 had a stronger ability to accumulate dry matter, but Nongda108 showed no yield advantage.
