to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

an experiment was conducted in order to evaluate the effects of humic acid spraying on  grain yield and yield components of wheat, in agricultural research and natural resources center of tehran province, in 2010-11. a split-plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments contains of normal irrigation, non-irriga...

in order to study the effects of drought stress and nitrogen (n) levels on grain yield, yield components and water use efficiency of grain corn (sc.704), a field experiment was conducted in 2009 growing season. the experiment was split-plot based on randomized complete block design arrangement and four replicates. main plots were three irrigation levels included optimum irrigation (i1), moderat...

in this study theeffect ofdrought stress was investigated on grain yield and oil rate and protein percentage of four varieties of castor in the climatic conditions of damghan. the experiment was done in the research farm of damghan islamic azad university(iran)in 2011 assplit plots in a randomized complete block design with three replications. the main plots of drought stress were 5, 10 and15 d...

in order to investigate drought stress and plant density the yield, yield components and protein of spotted bean grain (cultivar talash), an experiment was carried out as split plots in randomized complete blocks with three replications in yasouj, in 2012. factors of the test including irrigation in three levels; without stress (control treatment), water stress in vegetative stage (interrupting...

BACKGROUND: Drought stress and climate changes cause damage led to reduction in agricultural production. OBJECTIVES: Evaluation the impact of different levels of super absorbent polymer (SAP) on reducing the effects of drought stress on some physiological traits and activity of some antioxidant enzymes in wheat crop. METHODS: Current research...
