Means and, in parentheses, coefficients of variation (CV %) of nitrogen use efficiency (NUE) for grain yield (G w /N s), N uptake efficiency (N t /N s), N utilization efficiency (G w /N t), and N supply (N s) for winter wheat as influenced by tillage intensity (CT = conventional tillage, NT = no-tillage) and N fertilization rate (kg ha −1) in two years. Wheat (Triticum aestivum) has low nitrogen use efficiency (NUE). Better Crops. Wheat NUE is an important quantitative trait that is very complex and easily influenced by the environment and its controlling network is still not clear. One possible reason for the low observed efficiency of grain N recovery from fertiliser applied in the year of cropping may be the amount and speed of N movement in soil. During 2015-2017 a primary objective has been to evaluate the impact of N application, into a dry soil profile, during the fallow. (Loss will be discussed in greater detail below.) (2020). Here we examined the NUE patterns in two major fertilizer-consuming crops across the United States since 1970. A short summary of this paper.
