in order to investigate the competitive effects of wild mustard on yield and yield components of wheat cultivars, field experiments was conducted in gorgan reaserch station during 2010-2012 growing seasons. the experiments were laid out in four replicated, factorial arranged rcb design. factors of the experiments included five different densities of wild mustard (0, 4, 8, 16 and 32 plants.m-2) ...
Identification of adapted genotypes with high grain yield is the most important goal in durum wheat breeding programs. To study adaptation and grain yield stability of durum wheat genotypes, 18 durum wheat promising lines with two commercial durum and bread wheat cultivars were used. The durum wheat genotypes were evaluated in four locations; Isfahan, Karaj, Kermanshah and Neishabour in tempera...
in order to examination of dual purpose herbicides on some wheat physiological indexes in different stages of phenology of this corp, an experiment was conducted in 1386-1387, in kordkoy, golestan province with dry farming condition. this study was performed as factorial in randomized complete block design with 2 factors and 4 replications. the first factor included the type of herbicides: shov...
In order to study changes in morphophysiological traits of wheat cultivars released from 1940 to 2000 in Iran and to determine the association of these traits with grain yield, an RCBD experiment was conducted with 15 wheat cultivars released during past 60 years in Arsanjan (Fars province) in 2006 and 2007. Results indicated that grain yield increased significantly during these 60 years (r=0.9...
climate change is a phenomenon that has made the most concern in communities and decision making centers. this phenomenon has important effects on different aspects of human life. one of the most important crops that are affected by climate change is wheat. accordingly, data and information of northern khorasan have been used to study the effects of climate change on rain-fed wheat yield. for t...
wheat production with the least use of chemical inputs is an important goal of modern farming to decrease of negative effects of the use of chemical inputs. this paper has estimated the virtual profit of organic wheat in transition period using a cross sectional data of 453 wheat producers of khorasan razavi province during 2007. a model introduced to this objective so that it has ability of es...
just as motivation is important in sla research, demotivation constitutes an important factor, too. there are many studies done on demotivation and burnout of teachers. many of these studies have been conducted on one or two aspects of english instruction. consequently, there are few studies which have been done on more than two aspects of english teaching. the aim of this study is to find out ...
The objective of this experiment was to analyze genotype × environment (GE) interaction for grain yield of 20 durum wheat genotypes to identify the yield stability and adaptability of genotypes using GGE biplot method as well as some univariate stability statistics. The genotypes were evaluated in three rainfed stations of Sararood (Kermanshah), Maragheh and Shirvan, Iran under both rainfed and...
A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
