Although essential for achieving high crop yields required for the growing population
worldwide, nitrogen,(N) in large amounts, along with its inefficient use, results in …

Crop nutrient and especially nitrogen use efficiency (NUE) is both an economically and an
environmentally highly desirable trait. It has been estimated that only a third of nitrogen …

Globally it has been estimated that only one third of applied N is recovered in the harvested
component of grain crops. This represents an incredible waste of resource and the overuse …

Nitrogen is an essential element required for plant growth and development. However, over-
use of nitrogen fertilizer is not only costly but also environmentally unsafe. Therefore …

Improving nitrogen use efficiency (NUE) represents one of the main goals to reduce N input
in maximizing crop yield for sustainable agriculture. A NUE key strategy is the exploitation of …

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 …

Crop production has a large impact on the nitrogen (N) cycle, with consequences to climate,
environment, and public health. Designing better N management will require indicators that …

Nitrogen (N) losses are a major environmental issue. Globally, crop N fertilizer applications
are excessive, and N use efficiency (NUE) is low. N loss represents a significant economic …

Wheat cultivars differ in their response to nitrogen (N) fertilizer, both in terms of its uptake
and utilization. Characterizing this variation is an important step in improving the N use …

Wheat (Triticum aestivum L.) cultivars with improved nitrogen-use efficiency (NUE) under
low and medium N conditions will help to minimise production costs and nitrate-N …
