Investigation of Rate and Method of Nitrogen Application on Nitrogen Use Efficiency and Seed Yield of Safflower (Carthamus tinctorius L.)
Nitrogen fertilizer management has a special priority for safflower economic production. Increasing the efficiency of this element, in addition to increasing economic benefits, also reduces environmental pollution. Therefore, a factorial experiment was conducted in the form of statistical design of complete randomized blocks with three replications at Safiabad Agricultural and Natural Resources...
متن کاملStudy of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics
In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...
متن کاملAgroecosystems, 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-scale systems in developed countries and smal...
متن کاملeffect of nitrogen on water use efficiency of rain, nitrogen agronomic efficiency and soil moisture depletion under rainfed wheat
in order to study the effects of rate and application time of nitrogen on grain yield of rainfed wheat, water use efficiency of rain (wue), nitrogen agronomic efficiency (nae) and soil moisture depletion (smd), one experimental farm was carried out in kurdistan province during 2012-2014. tratments were five rates of nitrogen (n0, n30, n60, n90 and n120) kg.ha-1 as urea with three application ti...
متن کاملEffects of Mulching and Nitrogen on Soil Nitrate-N Distribution, Leaching and Nitrogen Use Efficiency of Maize (Zea mays L.)
Mulching and nitrogen are critical drivers of crop production for smallholders of the Loess Plateau in China. The purpose of this study was to investigate the effect of mulching and nitrogen fertilizer on the soil water content, soil nitrate-N content and vertical distribution in maize root-zone. The experiment was conducted over two consecutive years and used randomly assigned field plots with...
