in order to study the effect of water deficit effects on agronomic characteristics of sunflower ‎hybrids, three separate experiments were conducted as‏ ‏randomized complete block design with ‎three replications at the research field of seed and plant improvement institute - karaj. the first ‎experiment conducted at optimum conditions and plants were irrigated after 60 mm evaporation ‎from evapo...

in order to investigate the water deficit impact on physical characteristics of seed in four sunflower hybrids (azargol, allstar, hysun 33 and hysun25), under three irrigation regimes (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan, respectively) and experiment was conducted. sampling was done at the end of growing period (season) when the moisture conte...

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

to evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of agria cultivar potato, an experiment was carried out in the agriculture faculty of kermanshah. repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...
