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...
متن کاملTropical Legume Crop Rotation and Nitrogen Fertilizer Effects on Agronomic and Nitrogen Efficiency of Rice
Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...
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 کاملResponse of Seed and Oil Yields and Phosphorus Agronomic Efficiency of Soybean to Simultaneous Placement of Nitrogen with Phosphorus under Drought Stress
In order to study yield, yield components and agronomic efficiency of phosphorus in soybean affected by simultaneous placement of nitrogen with phosphorus, an experiment was carried out under moisture stress conditions, at Agricultural Research Station of Bu Ali Sina University, Hamedan, Iran in 2017 in a factorial split plot based on randomized complete block design with three replications. Th...
