Abstract In calcareous and saline soils, the adverse effect of some ions such as bicarbonate, boron, magnesium, and especially sodium, and the imbalance of nutrients’ concentrations are essential factors which reduce plant growth. A greenhouse experiment was conducted to study the effect of sodium (Na) and magnesium (Mg) on some growth traits and chlorophyll content of pistachio seedlings (cv....

The rice plant need the silicon element more than other nutrition elements, but its importance has not been clearly known. In order to study of silicon effect on the growth and yield of rice (Tarom Hashemi variety), an experiment was carried out in pot and field conditions with three replicates in the greenhouse and in the field of Rice Research Institute of Iran (Amol) in 2009 and 2010. Three...

In order to evaluate the effect of row and plant spacings on the yield and yield components of three cultivars of forge sorghum, a field experiment was conducted in Isfahan University of Technology, Lavark, during spring, 2001. Experimental design was a split-factorial with three replications. Main plots consisted of three row spacings (45, 60, 75 cm) and subplots were combinations of three cul...

Due to low organic matter content in most of the cultivated soils of Iran and occurrence of drought stress in plants because of low precipitation, application of sewage sludge compost has been recommended for increasing soil organic matter content and improving soil fertility, increasing crop tolerance to water deficit and improving crop yield. So, in this study, the effects of soil moisture an...

This study was carried out in order to examine the contrastive relationship between seed yield and agro-morphological traits in confectionery sunflowers at molecular and phonotypical level via association mapping and sequential path model. In this study, 50 confectionery sunflower populations gathered from different regions of country were studied in completely randomized design with ten replic...
