Efficiency of nitrogen fertilization in spring wheat
An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...

and Reule, 1994; Norwood, 2000; Peterson et al., 1993; Schlegel et al., 2002). No-till (NT) production systems, especially winter wheat (Triticum Dhuyvetter et al. (1996) reported that the more intenaestivum L.)–summer crop–fallow, have increased in the central Great sive cropping systems had higher profit potential than Plains, but few N fertility studies have been conducted with these systems...
متن کاملNitrogen Fertilizer Management in Dryland Wheat Cropping Systems
Wheat is the most widely cultivated food crop in the world, which provides nutrition to most of the world population and is well adapted to a wide range of environmental conditions. Timely and efficient rates of nitrogen (N) application are vital for increasing wheat grain yield and protein content, and maintaining environmental sustainability. The goal of this study was to investigate the effe...
متن کاملwater use efficiency of four dryland wheat cultivars under different levels of nitrogen fertilization
it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...
متن کاملNitrogen Fertilization of Wheat No-Till Planted in Alfalfa Stubble
The N available after legumes is sufficient for maximum crop yields in many cropping systems. Fertilizing without accounting for the "extra" N mineralized from legume residues can contribute to high nitrate-N concentrations in the soil during crop production and increase nitrate-N leaching potential. Tillage practices also affect the physical, biological, and chemical nature of the soil, changi...
