water deficient is one of the most important limiting factors in rapeseed (brassica napus l.) production in arid and semiarid areas speciallyiran, which is the best approach to deal with the introduction of resistant and compatible varieties to drought stress. the response of fourteen rapeseed cultivars to water stress was studied in a split plot experiment based on complete randomized block de...

in order to investigate the effect of insufficient irrigation on remobilization percent and plant dry mater in three spring safflower (cartamus tinctorius l.) genotypes, a field experiment was conducted at research farm, faculty of agriculture, the university of birjand, iran, during 2008-2009, as a spilt plot arrangement based on randomized complete block design with four replications. irrigat...

There is a need to optimize water-nitrogen (N) applications to increase seed cotton yield and water use efficiency (WUE) under a mulch drip irrigation system. This study evaluated the effects of four water regimes [moderate drip irrigation from the third-leaf to the boll-opening stage (W1), deficit drip irrigation from the third-leaf to the flowering stage and sufficient drip irrigation thereaf...

in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...

damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. in order to evaluate the effect of supplemental irrigation on safflower fly (a. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...

in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...

To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In ...

due to limited water resources, applying efficient water use in agriculture is very important. this experiment was carried out in kabootarabad agricultural research station for two years using split plots in a randomized complete block design with four replications. six irrigation treatments based on evaporation from class a pan were applied as the main factor at three cotton growing stages, na...
