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 کاملGrowth Response of Winter Wheat (Triticum aestivum L.) and Wild Barley (Hordeum spontaneum Koch) to Nitrogen
A greenhouse study was conducted to investigate the effects of nitrogen (N) on wild barley (Hordeum spontaneum Koch) interference with winter wheat (Triticum aestivum var. Pishtaz) by an additive series experiment. The experiment was conducted in a split plot design with 3 replications. Wheat plant height losses were on average 30, 10, and 10% in a wild barley density of 16 plants per pot with ...
متن کاملInvestigating the Combined Effect of Tillage, Nitrogen Fertilization and Cover Crops on Nitrogen Use Efficiency in Winter Wheat
A field study was conducted in northern France over two consecutive years to evaluate the combined effect of conventional tillage (CT) vs no till (NT) with or without cover crops (cc) and nitrogen (N) fertilization on various agronomic traits related to N use efficiency in winter wheat. Five years after conversion of CT to NT, significant increases in N use efficiency, N utilization efficiency,...
متن کاملIrrigated hard winter wheat response to fall, spring, and late season applied nitrogen
High yielding irrigated hard red winter wheat (HRW, Triticum aestivum L.) is frequently low in protein and marketed at a discount. Protein is affected by available nitrogen (N) but few published reports relate to N fertilization practices for producing high yielding irrigated hard red winter wheat with acceptable protein in arid environments. A three year study (1985–1987) was conducted (1) to ...
متن کاملEffect of sulfonylurea herbicides residues on growth and yield of sunflower in rotation with wheat
To evaluate the effect of residue of sulfonylurea herbicides and wheat residues on the growth and yield of sunflower, a split factorial experiment was conducted based on a randomized complete block design (RCBD) with four replications at the College of Agriculture, Shiraz University, Shiraz, Iran. The treatments included with and without wheat residues from the tested farm as the main plots, a...
