A field experiments was conducted at the Agricultural University, Wenxi, Shanxi China. During the winter season of 2017-2019 in which three sowing methods were applied: wide space sowing (WSS), furrow sowing (FS) and drill sowing (DS) along with four nitrogen levels (150 kg center dot hm(-1), 225 kg center dot hm(-1), 300 kg center dot hm(-1) and 375 kg center dot hm(-1)). The present study was designed to evaluate the effect of tillage condition on nitrogen, production and consumption, protein content/yield and grain yield of dryland wheat. The wide space sowing method has extremely significant effects on the number of ears, thousand grain weight and yield of winter wheat and also it significantly increased nitrogen absorption efficiency by 50%, nitrogen fertilizer production efficiency by 51%, the number of ears and yield were also significantly increased by 22%, 46% and the content of protein, globulin, gliadin and gluten in grains were the highest in furrow sowing, while the yield of albumin and grain protein were the highest in wide space sowing. The wide space sowing WSS and a nitrogen level of 300 kg center dot hm(-1) was beneficial to increase water consumption during the growth period, also to increase the tiller dynamics, improve the dry matter quality of the plant, and to improve nitrogen absorption and nitrogen fertilizer production efficiency by increasing grain protein.
