TL;DR: In this article, the authors quantify the genotypic variation in total nitrogen uptake by grain and straw (total-Nup), and in nitrogen utilization efficiency for grain yield (grain yield per unit of N taken up) (grain-NutE).

TL;DR: It is concluded that increased root length density at depth and a high capacity for N accumulation in the stem are of particular value for increasing NUE in feed wheat cultivars and for bread-making cultivars, high NUE may be associated with high capacities for uptake and assimilation of N, with high post-anthesis N remobilization efficiency and/or specific grain protein composition.

TL;DR: In this paper, the authors examined the environmental impact of different nitrogen (N) fertilizer rates in winter wheat production by using a new life cycle assessment (LCA) method, which was specifically tailored to crop production.

TL;DR: The mechanical and physiological bases for root growth against high mechanical impedance are reviewed and differences between species or cultivars in their ability to penetrate strong layers may be due to differences in the tendency of roots to deflect or buckle when they grow from a weak to a strong environment.

TL;DR: The relationship between grain yield and the amount of root at anthesis was investigated and total root length was positively correlated with grain yield but nonetheless similarly yielding crops could have different-sized root systems.
