Effects of Different N-fertilization on the Growth of Maize with Straw in the Field

Qi Wang

Abstract

The effects of six N-fertilization on the yield and agronomic traits of maize with straw in the field were studied.The results showed that treatment 3 had the highest dry matter,economic factors and yield.The treatment 3 obtained yield 9 027 kg·hm~(-2),it was increased 4.7%compared to the control.The results suggested that the rational rotation system in combination with straw should be polulalized.
