Nitrogen fertilization and planting density are two key factors that influence the yield of rice. Reducing nitrogen fertilizer input increasing will help to improve use efficiency stabilize yield. Field 15N tracer method in plot experiments were conducted study trends yield, (NUE) transfer hybrid rice conventional under dense with a reduced rate (DPRN) sparse high (SPHN). Among plants, proporti...

ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...

Fertilization with nanoparticles offers alternatives to improve the efficiency of nutrient absorption in a sustainable way crops. The objective this work was study influence foliar application zinc-molybdenum nanofertilizer (Nano ZnMo) on nitrogen (N) use (NUE), as well yield parameters and N assimilation green bean plants cv. “Strike”. Three doses Nano ZnMo (0, 4 8 ppm) were applied combinatio...

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...

As a widely implemented irrigation regime for paddy fields, water-saving (WSI) is capable of ensuring water resource security and improving nitrogen use efficiency (NUE). Higher gaseous losses (GNL) lead to low recovery rate basal nitrogen, this the primary reason that restricts further improvements in NUE under WSI. The deep placement fertilizer (DPN) considered an efficient agricultural manag...

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...

in order to evaluate the effects of different levels of potassium and nitrogen on nitrogen use efficiency (nue) and yield of rapeseed (hyola 401), a field experiment was conducted at rice research institute of iran (rasht) in a factorial experiment based on a complete randomized block design with 3 replications for two years (2008-2010). the first factor was pure potassium fertilizer in three l...
