To investigate the interactive effects of atmospheric carbon dioxide concentration ([CO(2)]) and nutrition on photosynthesis and its acclimation to elevated [CO(2)], a two-way factorial experiment was carried out with two nutritional regimes (high- and low-nitrogen (N), phosphorus (P) and potassium (K)) and two CO(2) concentrations (360 and 720 ppm) with white birch seedlings (Betula papyrifera...

Increasing water and nitrogen use efficiencies (i.e., WUE NUE) in dryland agroecosystems to maintain high agricultural output with lower environmental costs, such as minimal soil depletion nitrate-N residue, are key responsibilities assure food security for a growing global population. The impact of N rate on balance, nitrate grain yield, WUE, crop recovery efficiency (REN), agronomic fertilize...

Nitrogen and sulphur are fundamental macronutrients for the production of sunflower crop. is required consistently in larger amounts while common urea has more losses due to high solubility. On other hand, application increases oil contents availability essential nutrients (N, P, K). Therefore, combined polymer coated with fertilization might be a promising option which can increase achene yiel...

Preplant nitrogen (N) application, which involves placing nutrients in the soil before seeding, has been an integral part of crop production systems for decades. Some producers are known to apply N at least 21 d planting. This may increase loss and lower grain yield. study evaluated effect timing rate application on winter wheat (Triticum aestivum L.) yield use efficiency (NUE). An experiment w...

Effective water and nitrogen (N) management strategies are critical for sustainable agricultural development. Lysimeter experiments with two deep percolation rates (low high percolation, i.e., LP HP: 3 mm d−1 5 d−1) five N application levels (N0~N4: 0, 60, 135, 210 285 kg ha−1) were conducted to investigate the effects of controlled drainage on productivity (WP) use efficiency (NUE) in water-sa...

Water and nutrient use efficiencies are important adaptive features of plants in arid semi-arid environments. In this study, water, nitrogen (N), phosphorus (P) Stipa purpurea Griesb., an endemic dominant grass species, were investigated the alpine steppe along precipitation gradients on Tibetan Plateau. The leaf N content S. increased gradient, but P decreased, whereas carbon (C) remained unch...

Tea brewed from leaves of Camellia sinensis (L.) is one the most popular worldwide non-alcoholic beverages, and nitrogen an essential nutrient that affects growth development tea plant. Inorganic organic are major forms absorbed by plant also play important role as a vital signaling molecule, which use efficiency (NUE) C. in its period. In addition, improving NUE therefore for economic environm...

There is evidence that crop yields are showing a trend of stagnation in many countries. This review aims to make an inventory of the last decade's crop productions and the associated economic and environmental challenges. Manipulating nitrogen use efficiency in crops appears to be the best way to conciliate global food security, respecting environmental policies, and the need to produce biofuel...
