Nitrogen affecting switchgrass yield, nitrogen removal, and use efficiency [PDF]
Best management practices for switchgrass (Panicum virgatum L.) fertilization in the production of biofuel feedstock and forage hay are variable depending on climate, harvest timing, and variety.

NITROGEN USE EFFICIENCY IN SWEETPOTATO [PDF]
Eight clones of sweetpotato [Ipomaea batatas (L.) Lam.] at five N levels in 1992 and five clones at three N levels in 1993 were evaluated for genotypic variation in N use efficiency [NUE (yield/unit N fertilizer applied)], uptake efficiency (N accumulated/unit N fertilizer applied), and utilization efficiency (yield/N accumulated).

Global terrestrial nitrogen uptake and nitrogen use efficiency
AbstractPlant biomass production (BP), nitrogen uptake (Nup) and their ratio, nitrogen use efficiency (NUE), must be quantified to understand how nitrogen (N) cycling constrains terrestrial carbon (C) uptake. But the controls of key plant processes determiningNupand NUE, including BP, C and N allocation, tissue C:N ratios and N resorption efficiency ...

Effect of Nitrogen Fertilizer and Irrigation Levels on Yield and Some Physiological Traits of Wheat under Drip Irrigation [PDF]
IntroductionWheat is globally one of the most critical cereals. It is necessary to increase its yield to cope with the increasing population through management improvement or breeding due to decreased arable lands.

Agroecosystems, Nitrogen-use Efficiency, and Nitrogen Management
The global challenge of meeting increased food demand and protecting environmental quality will be won or lost in cropping systems that produce maize, rice, and wheat. Achieving synchrony between N supply and crop demand without excess or deficiency is the key to optimizing trade-offs amongst yield, profit, and environmental protection in both large ...

Feeding the world sustainably: efficient nitrogen use
Globally, overuse of nitrogen (N) fertilizers in croplands is causing severe environmental pollution. In this context, Gu et al. suggest environmentally friendly and cost-effective N management practices and Hamani et al. highlight the use of microbial inoculants to improve crop yields, while reducing N-associated environmental pollution and N ...
