Performance of Nitrogen Fertilization and Nitrification Inhibitors in the Irrigated Wheat Fields

چکیده
Effective nitrogen (N) management practices are critical to sustain crop production and minimize nitrate (NO3−) leaching loss from irrigated fields in the Columbia Basin (U.S.), but studies on applied limited. Therefore, 2014 2016, two separate field were conducted sandy loam soils region evaluate performance of various N fertilizers spring winter wheat. The treatments consisted nitrification inhibitors (NIs) (Instinct® II Agrotain® Ultra) combination with (urea urea ammonium [UAN]) under application methods (single vs. split-application) rates (100% 85% growers’ standard). results these trials demonstrated that fertilizer did not affect wheat grain yield (GY) protein (GP). In trial, higher NH4⁺-N content lower NO3−-N was observed UAN (0–30 cm). However, NIs had no considerable effect soil content. split generally reduced total mineral (TMN) content, especially at 30–60 cm, comparison a single application. use Instinct® tended reduce TMN contents, while Ultra effective inhibiting nitrification. Our findings suggest more effectiveness applications would enable growers optimize efficiency region.

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...
