the effect of drought stress on yield and components of three varieties of autumnal rapeseed in the south eastern region of isfahan, utilizing four irrigation regimes (i.e. no irrigation from flowering stage on, no irrigation from the podding stage on, no irrigation from grain filling stage on, and a normal irrigation regime after 80 mm evaporation from class a evaporation tube) were studied...
Soybean (Glycine max) is sensitive to drought stress, and increasing its yield, requires the selection of tolerate varieties which are adapted to semiarid or low water climates of Iran. In this research, the experiment was performed based on a factorial completely randomized design with three replications at 2013. Experimental factors were consisted of 8 genotypes of soybeans and 6 levels of dr...
The negative effects of water stress, reduced water use and nutritional disorders in plants. So in order to study the effects of foliar application of iron and manganese on some morphological and physiological characteristics of Mungbean (cultivar beam) under water deficit stress, this experiment was conducted in the Faculty of Agriculture of Tarbiat Modares University as randomized complete bl...
Drought as one of the most important environmental stresses causes serious threats in amount and efficiency of crop productions. To evaluate drought resistance by using drought tolerance indices in safflower varieties, a research was conducted at the Research Farm of Bu-Ali Sina University. Experiment was planed as split-plot on the basis of randomized complete block design with three replicati...
Investigating the crop response to the deficit irrigation and evaluating the effect of drought stress on plant is one of the most important issues in crop production. In these circumstances, the use of organic fertilizers can play a mitigative role. Hence, an experiment was laid out as split plot based on randomized complete blocks design with three replications in Research Farm of University o...
To investigate the effects of drought stress on the water stress, osmotic adjustment and stay green of sorghum genotypes and their relationship with grain yield, a split-plot on randomized complete block design with three replications was conducted at the experimental field of Seed and Plant Improvement Institute, Karaj, Iran in 2015. The main factor was three treatments: control (irrigation af...
To investigate the physiological responses of sunflower (Helianthus annuus L., Alstar hybrid) to water stress under different levels of zinc fertilizer, an experiment was conducted at the Isfahan Agricultural Research Center, Isfahan, Iran, during 2008 and 2009 using a randomized complete block design within a split plot layout with three replications. Five irrigation treatments used in thi...
background and objectives: drought is one of the most important factor limiting plant growth around the world and the most common environmental stress which is limited produce approximately 25% of the world's land. production of secondary metabolites in medicinal plants changes by environmental condition and also water stress is effective factor in growth and synthesis natural compounds in...
In order to study the effect of salicylic acid and selenium foliar application on physiological characteristics, yield and yield components of safflower (Carthamus tictorius L.) under drought stress conditions, an experiment was conducted as split plot based on randomized complete block design with three replications. The main factor included irrigation in three levels, complete irrigation duri...
In order to study the effect of irrigation withholding and biofertilizers application on quantitative and qualitative yield and grain filling duration of sunflower (Helianthus annus L.), a factorial experiment was conducted based on randomized complete block design with three replications in research field of Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili, Iran i...
