Selecting and cultivating the crops/varieties that can tolerate water salinity is potentially animportant strategy to save fresh water resources and maximize the crop yield in salt affected areas.To evaluate the responses of 36 sorghum lines and cultivars to salinity stress, two fieldexperiments were conducted in non-stress (EC=2 dS/m) and salinity stress conditions (EC=12dS/m) using randomized...

introduction drought stress as the most important abiotic stress plays an important role in yield reduction of crops worldwide. considering the extends and problems caused by the moisture stress, agronomic and breeding strategies in reducing yield loss are essential. in this regard, the identification and selection of effective characteristics of wheat under drought stress in increasing yield, ...

in order to study of drought stress on physiological and agronomicalcharacteristics of rapeseed varieties, an experiment was carried out as split plot basedon randomized complete block design with three replications at yazd region duringof 2011-2012. irrigation treatments was designed in two levels as main plot includingirrigation after 80 mm evaporation from evaporation pan, class a (control t...

this study was conducted to determine the effect of cliniptilolite natural zeolite on deficit irrigation stress tolerance on maize cultivar ksc704. the experiment was laid out as a factorial design based on randomized complete block with three replications at seed and plant improvement institute, karaj in 2012. four irrigation levels, including irrigation after 70, 95, 120 and 145 mm cumulative...

the effects of water deficit on grain yield, yield components and the physiological char-acteristics of barley (hordeum vulgare l.) varieties were studied in a split plot design dur-ing the 1999-2000 growing season in karaj, iran. five irrigation levels [0, 25, 50, 75, and 100% crop water requirements (cwr)] and six barley varieties karoon kavir , rei-hani(drought tolerant), torkman , c-74-9 (i...
