Abstract :

In order to study the effect of selenium foliar application on morphological traits, yield and yield components of safflower (Carthamustinctorius .L) under drought stress an experiment in split plot based on complete block design with three replications in 2014 in Varamin region. The first factor drought stress in four irrigation regimes were 50 (Control), 80, and 110 mm evaporation from evaporation pan (Class A) and the second factor consisted of four levels of selenium (Control, 100, 200 and 300 mg.lit) respectively. Results showed a significant effect of drought stress and selenium on on plant height, height offer branching of the soil, head diameter, grain yield, biological yield, 1000-grain weight, number of seeds per head, number of heads and number of branches, but the effect of treatments on stem diameteris not significant. Interactions between drought stress and selenium was significant and the best results in normal irrigation (control)and 300 mg treatment was obtained
