investigation of drought event has a great importance in the natural resources management and planning water resources management. in this research, the effect of the climate change on drought characteristics in northwest of iran was investigated using the hadcm3 model under a2 scenario. the statistical downscaling was executed using sdsm 4.2.9 and observed daily precipitation, observed predict...

boron toxicity is becoming more extensively widespread in arid and semi arid regions, due to the application of either saline waters or irrigation waters containing a relatively high b content. results of research indicate that addition of certain plant nutrients such as n may reduce the harmful effect of high b levels. therefore, the present experiment was undertaken to evaluate the interactiv...

in order to study the complementary effects of application time of two herbicides sulfosulfuron 75% wg (apyrus) and 75% sulfosulfuron + 5% metsulfuron-methyl (total) and planting wheat density on wild barley (hordeum spontaneum koch.) control, an experiment was conducted in randomized complete blocks design with two-factors during 2012-2013 growing season in zarghan (fars). the first factor was...

two-year experiments was conducted to find the effect of value and times of supplementary irrigation on water requirement and yield production of three new wheat cultivar namely (‘w33g’, ‘cross alborz’ and ‘bahar’) in three replicate randomized complete block factorial experiments since 2009-11. experiments were performed at the campus of agriculture and natural resources of razi university lys...

the aim of this paper is to determine the different types of theatrical policies applied by the states of iran within the years 198 9(the start of the first presidency of akbar hashemi rafsanjan) to 2009 (the end of the first presidency of mahmoud ahmadi nejad). the method of this research is content analysis. the cabinet approvals within these years which either in their titles or in their tex...

to design the equipment and facilities for preservation, storage and processing of pomegranate, it is necessary to know the specific heat and thermal conductivity of the fruit components. the specific heat of exocarp, mesocarp and of seeds of pomegranate were assessed at three moisture content levels (30, 50 and 76% for seed and mesocarp; 15, 35 and 52% for exocarp) and at four temperature leve...
