Due to the asymptotic nature of the crop yield response curve to fertilizer N supply, the
nitrogen use efficiency (NUE, yield per unit of fertilizer applied) of crops declines as the crop …

Background We collated estimates of the percentage of legume N derived from atmospheric
N 2 (% Ndfa) for 14 major grain legumes and then analysed and aggregated the data to …

Core Ideas As N2 fixation (%) increased, seed production per N2 fixation decreased. The N‐
gap between crop N uptake and N supplied by N2 fixation rose when contribution from …

As soybean yield continues to increase, it seems critical to know if there is a yield level at
which potential contribution of indigenous nitrogen (N) sources (N fixation and soil …

In semi-arid regions of northwest China, the planting pattern of double ridge-furrow with full
film mulching (DRFM) is widely used to improve maize productivity. However, little is known …

Due to depleting water supplies and the cultivation of high water-demanding crops like rice,
water deficit in crop production has become a major concern, especially in semi-arid regions …

Understanding factors underpinning the variability in nitrogen (N) utilization efficiency
(NUtE)[ie grain yield per unit of N uptake at maturity (Nup MAT)] is critical to direct future …

Legumes rely on soil mineral nitrogen (N) and biological N fixation (BNF). The interplay
between these two sources is biologically interesting and agronomically relevant as the crop …

Biological N 2 fixation (BNF) and mineral soil absorption are complementary N sources for
soybean growth. BNF is sensitive to nutrient and environmental conditions, though a …

Legumes' nutrition relies on two sources of nitrogen (N): mineral N from soil, and biological
N fixation (BNF). The aim of this study was to verify the effect of bacterial inoculation, as well …
