In order to investigate the effect of saline irrigation water and potassium spraying treatments on the yield and photosynthetic assimilate partitioning coefficient, a study was conducted in 2014 in the form of split factorial experiment in a randomized complete block design with four replications at Rudasht Salinity and Drainage Research station in Isfahan, central Iran. Irrigation water treatm...

To evaluate the effect of salinity stress and Zinc application on grain filling of three barley cultivars and some physiological traits this this experiment was arranged as a split block in a randomized complete block design with three replications at the Esfahan (Rodasht) salinity research station (2013-14). Three water quality treatments including (2, 10 and 18 dS/m) were evaluated in vertica...

To investigate the effects of sodium chloride on two safflower cultivars (LRV 51/11 and LRV 51/51(padideh), four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a randomized complete block design with four replication in a controlled environment of the greenhouse during 2008-2009. The desired salinity levels were developed by mixing the required amou...

abstractbackground and objectives: in most saline and non-saline soils, nitrogen is the most restrictive nutrient for plant growth. in saline soils, interactive effects of salinity and soil fertility is very important from optimum production. nutrient imbalance is one of the problems with saline soils. in these circumstances, the fertilizer application may to increase osmotic effect of salt, th...

To evaluate the effect of soil salinity stress on some vegetative and reproductive traits of sunflower (Helianthus annus L.) oil varieties in Mahabad conditions, a factorial experiment was conducted in greenhouse condition based on randomized complete block design with five replications in 2009. Treatments were included five levels of soil salinity (EC: 0.5 (as control), 2, 4, 6 and 8 ds /m) an...
