Read More To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In this experiment, the major factor of drought stress treatment included four levels (optimum irrigation, stopping the irrigation at flowering stage, stopping the irrigation at seed formation stage and stopping the irrigation at two stages of flowering and seed formation). The minor treatment factor consisted of Fe nanoparticles foliar application at four levels (non-applying the foliar, foliar application at flowering stage, foliar application at seed formation stage and foliar application at two stages of flowering and seed formation). After data analysis by SAS software, the parameters including analyses of variance and means were compared using the Duncan's Multiple Range Test at probability level of 5%. The results showed that the effects of drought stress and Fe nanoparticles were significant at probability level of 1% on traits such as the number of boll per branch, number of seeds per boll, the thousand seed weight and yield at probability level of 1%. Among the levels of drought stress, the highest yield and yield components losses were seen for most of the traits and between the levels of 2 times drought stress. The maximum yield and yield components rates related to the control treatment (optimum irrigation). Also, among the levels of Fe nanoparticles, the use of nanoparticles produced the highest rates of yield and yield components in two stages of flowering and granulation. Also, the foliar application at flowering stage was better than seed formation. Meanwhile, the control treatment had the lowest yield and yield components. Finally, the interactions of Fe nanoparticles and different levels of drought stress at 1% probability level had significant impacts on traits, including boll number per branch, number of seeds per boll, the thousand seed weight and the yield. At the end of the experiment, the 2 times stress had the highest yield and yield components losses, and 2 times of using nanoparticles had the highest rates of yield and yield components. Thus, the adverse effects of drought stress can be reduced in this area and similar areas by application of Fe nanoparticles.

Read More In order to study the effect of bio-fertilizers in decrease the effects of water stress on yield, yield components and oil percentage of Goldasht spring safflower cultivars (Carthamus tinctorius L.), an experiment on split plot in a randomized complete block design with three replications was carried out in 2012 at the Agricultural Research Station of Islamic Azad University of Roudehen branch .In this experiment, the main plot was water stress treatment consisted of four levels (optimum irrigation, cutting of irrigation at flowering, cutting of irrigation at seed formation, cutting irrigation at in two stages of flowering and seed formation) and bio-Fertilizers treatment as subplot consists of four levels (no fertilizer, consumption of nitragin bio-fertilizer, consumption of seaweed extract and seaweed extract and nitragin biofertilizer respectively). Data were analyzed by SAS program of analysis variance and means at the 5% level LSD tests were compared. The results showed the effect of drought stress and biofertilizer treatment on traits such as number of seeds per boll, seed thousand weight and yield at 1% level was significant and effect of treatments on. Between stress levels, the highest yield and yield component losses for most traits and between levels 2 and the highest yield stress was observed in the control treatment (optimum irrigation) Also, between the used levels of biofertilizers, nitragin with seaweed extract produced the highest yield and usage of of nitragin was better than algae extracts and in the control treatment had the lowest yield. Finally effect of different levels of biofertilizers and different level of drought stress on plant height, chlorophyll b, number of seeds per boll, seed thousand weight, oil percentage and yield in 1% probability level and on the boll number per each branch in 5% probability level was significant. At the end, 2 times stress has greatest losses and nitragin with seaweed extract has highest level in yield and yield components. So in this area and similar areas can reduce the side effects of drought by using biofertilizers.
