Growth and nitrogen productivity of drip-irrigated winter wheat under different nitrogen fertigation strategies in the North China Plain

Journal of Integrative Agriculture, 2023
Excessive application of nitrogen (N) fertilizer is the main cause of N loss and poor use efficiency in winter wheat (Triticum aestivum L.) production in the North China Plain (NCP).

Agroecosystems, Nitrogen-use Efficiency, and Nitrogen Management

AMBIO: A Journal of the Human Environment, 2002
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

Trends in Plant Science, 2023
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 ...

Controlled traffic farming effects on productivity of grain sorghum, rainfall and fertiliser nitrogen use efficiency [PDF]

, 2021
Controlled traffic farming (CTF) is a mechanisation system in which all machinery has the same (or modular) working and track width so that field traffic can be confined to the least possible area of permanent traffic lanes.

Crop Performance Indexes Applied to Legume Used as Summer Cover Crops under Water Deficit Conditions

Agronomy, 2022
Summer legume cover crops (CC) such as Crotalaria juncea, Crotalaria spectabilis, Crotalaria ochroleuca, and Cajanus cajan could offer diverse advantages for the environment and productive cropping systems.

NITROGEN USE EFFICIENCY IN SWEETPOTATO [PDF]

HortScience, 1996
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 ...

Nitrogen affecting switchgrass yield, nitrogen removal, and use efficiency

Agrosystems, Geosciences & Environment, 2020
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.

Rapid Generation of Barley Mutant Lines With High Nitrogen Uptake Efficiency by Microspore Mutagenesis and Field Screening

Frontiers in Plant Science, 2018
In vitro mutagenesis via isolated microspore culture provides an efficient way to produce numerous double haploid (DH) lines with mutation introduction and homozygosity stabilization, which can be used for screening directly.

Global terrestrial nitrogen uptake and nitrogen use efficiency

Journal of Ecology, 2022
Abstract Plant biomass production (BP), nitrogen uptake ( N up ) 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 determining

Farming the planet with better nitrogen use [PDF]

, 2023
Feeding an increasingly affluent population is a huge challenge facing global agriculture. In contrast to “large-scale farming” in developed economies (e.g.
