Water sources optimizing required a suitable irrigation program. Different material can use to increase water use efficiency. Superabsorbent is one of the materials where used in around the world. These materials put in the soil and absorb water so that reserved water is usable by plant in the time of drought stress and they can reduce stress and lead to prevent yield loss. Therefore, the exper...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
Drought is considered as the most important constraint to world’s crop production. Furthermore arid and semiarid climate accounts for nearly most of terrestrial areas of Iran. Therefore in order to study the effect of irrigation regimes on growth, physiological attributes and grain yield as well as components of such a crop plant as safflower a 4-replicate split plot RCBD field study was perfor...
seedling characteristics of different sunflower (helianthus annus l.) cultivars under drought stress and inoculation with the azospirillum lipoferum in a spilt-factorial layout based on randomized complete block design with three replications were evaluated. treatments included dehydration stress (seed produced on maternal plants which irrigated after 60 (desirable irrigation), 120 (medium stre...
this study was an attempt to investigate and compare the effect of lexical inferencing and concept mapping on developing vocabulary retention of iranian language learners. sixty homogeneous students from different intact classes who were being taught as intermediate learners in sokhan english institute participated in this study. they were in different classes. a teacher made test as a pre-test...
To evaluate and select the promising lines of dual purpose grain-forage sorghum under drought stress conditions, a field experiment assplit plot arrangements in randomized complete block design with three replications was carried out atresearch field station of Seed and Plant Improvement Research Institute, Karaj, Iran, in 2014 and 2015 growing seasons. Irrigation levels (60 mm, 120 mm and 180 ...

two field experiments were conducted at the research farm of the faculty of agriculture, university of tabriz, iran during 2009-2010 and 2010-2011, to evaluate the response of fennel (foeniculum vulgare l.) landraces to limited irrigation. experiments were arranged as split plot based on randomized complete block design in three replications with irrigation treatments (irrigation after 60, 90, ...
proper irrigation scheduling, i.e. timely and adequate irrigation is an important prerequisite to profitable crop production. high temperatures along with soil moisture deficits are some of the main limiting factors for canola (b. napus l.) production in dry land cropping systems. these factors negatively affect the formation of pods during the flowering stage, resulting in decrease in seed yie...
Salicylic acid (SA) is a phyto-hormone that regulates physiological and biological processes in plants and can be used to improve plant growth under different environmental conditions, including water stress. Thus, a field experiment as split plot factorial based on randomized complete blocks design with three replications was conducted in 2014 to investigate the effects of fertilizer and salic...
