Abstract :
In order to investigate the effect of supplemental irrigation and foliar application of methanol concentrations on quality, and some physiological traits of safflower, an experiment was conducted as split-plot in a randomized complete block design in three replications, in the 2014-2015 crop year on the farm Kamalvand located 5 km from the Khorramabad Azad University. Treatment consisted of methanol at four levels (foliar application of water, methanol with a concentration of 15, 20 and 25% by volume) and supplemental irrigation at three levels (no supplemental irrigation supplementary irrigation systems and irrigation in both stage Additional Rate and grain filling stage of boll respectively). The results showed that leaf area index, relative water content, leaf greenness index in the seed stage of supplemental irrigation and grain filling, but the highest percentage of protein obtained in the absence of supplemental irrigation. The highest leaf greenness index, protein and oil content by volume of methanol at a concentration of 20% was seen, but most LAI was observed in methanol at a concentration of 25% by volume. In conclusion, in order to achieve maximum quality and quantity of supplementary irrigation in both stage and grain filling and methanol at a concentration of 20% by volume relative to the rest of the trial a more suitable.
