Investigation the apply of selected chemical compounds to increasing the quality and yield of pistachio "Akbari cultivar" in fresh and salty water and soil conditions

In this research, the effect of application of two effective chemicals on bud-break for increasing pistachio (Pistacia vera L.) economic yield in Akbari cultivar in salty (16.1 dS/m) and non-salt (3.9 dS/m) conditions in Gerd kouh and Bahadoran regions was investigated based on a randomized complete block design (BCRD) in compare to oil volk 5.5% and 6% and control. Selective compounds were (soybean oil 5.5 and 6%+ kno3 0.5%) and soybean oil 5.5 and 6%+ kno3 0.5%+ GA 20 mg/l). Each treatment was performed with 50 replications and four observed for each replication. In all regions, the effect of treatments was investigated on the traits related to quantity, quality and nut yield and finally, statistical data analysis was performed using SAS software (version 9.1) and economic calculations related to each treatment were performed in compare to the commercial treatment. The results showed that application of (soybean oil 5.5 and 6%+ kno3 0.5%) and (soybean oil 5.5 and 6%+ kno3 0.5%+ GA 20 mg/l) compounds on Akbari cultivar in Gerd Kouh and Bahadoran regions by increasing the percentage of fruit set, average number of seeds per cluster and decreasing the blank nuts percentage were increased the nut economic yield per hectare in compare to control and oil Volk treatments. treatment (soybean oil 5.5 and 6%+ kno3 0.5%) in Gerd Kouh and Bahadoran regions was increased nut yield rate 49.75% and 44.13% in compare to control and 6.91% and 3.07% in compare to oil Volk 5.5 and 6% respectively. Also, treatment (soybean oil 5.5 and 6%+ kno3 0.5%+ GA 20 mg/l) in Gerd Kouh and Bahadoran regions was increased nut yield rate 104.03% and 107.83% in compare to control and 45.43% and 48.39% in compare to oil Volk 5.5 and 6% respectively.
