abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
In order to evaluate the effect of different rates of nitrogen (N) and corn, rapeseed, sunflower and wheat residues on plant height, biological and grain yield and N use efficiency of wheat, an experiment was conductedduring 2010-2011 at Agricultural College of Shiraz University. The experimental design was split-split plot based on RCBD with four replications. Treatments were N (45, 90, 135 an...
Effect of Leaching on Reducing the Phytoxicity of Some Medicinal Plants on Wheat (Triticum aestivum)
The aim of this study was to investigate the effect of leaching on the reduction of soybean (Glycin max), black cumin (Nigella sativa), dill (Anethum graveolens) and dragonhead (Dracocephalum moldavica) residues allelopathy in wheat (Triticum aestivum) cropping. The experiment was conducted in a completely randomized design with three replications in 2017. The factors consisted of four types of...
Allelopathic effects of plant residues is an important research avenue regarding optimization of rotation systems in agronomy. The aim of this study was to investigate the allelopathic effects of four plant residues, namely, black cumin, dragonhead, dill, and soybean on the germination and growth of wheat (Triticum aestivum) in different cropping systems. Results showed that applicatio...
crop residues management is one of the most important factors to sustain agro-ecosystems. application of plant residues as organic fertilizers has functional role on the amount of soil elements, their availability for crops and finally yield obtained. in order to investigate the effect of different crop residues and their management on providing wheat potassium requirement, a four-replicated fi...
Limited information is available on the effect of residues rates and slope direction on dryland wheat (Triticum aestivum L.) yield. This study was carried out to determine the effects of residues rates and tillage direction on grain yield and yield components of the Sardary wheat in a dryland region in Zanjan. Five wheat residues rates (0, 25, 50, 75 and 100% surface cover) were applied and i...
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...

Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...
Limited information is available about the effect of preceding crop residues on bioavailability of zinc (Zn) in calcareous soil and its accumulation in wheat grain. In this experiment, residues of five crops including safflower (Carthamus tinctorius L.), sunflower (Helianthus annuus L.), bean (Phaseolus vulgaris L.), clover (Trifolium pretense L.) and sorghum (Sorghum bicolor L.) were incorpora...
