1 - Effects of Liquid Soap and Dishwashing Detergent on Pistachio Trees
Nazanin Vahabzadeh Mohammad Reza Hassani Sohrab Imani Hossein Allahyari Mahmoud ShojaiThe common pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Aphalaridae) is the key pest of pistachio trees in Iran.

Nowadays, pistachio growers use detergents widely to control this pest in pistachio orchards. Consequently, the study was carried out to investigate the effects of applying liquid soap (Jonobgan®) 3500 ppm, dishwashing detergent (Rika®) 3500 ppm, and conventional insecticides (spirotetramat (Movento®) 300 ppm and phosalon (Zolon®) 2500 ppm, periodically on some characteristics of “Fandoghi” pistachio trees, including sodium and potassium contents of leaves and bud abscission rate over three years. The field experiments were done in a randomized complete block design with three treatments and three replications in Rafsanjan. The results showed that the application of liquid soap and dishwashing detergent caused no significant variation in sodium and potassium contents of leaves and bud abscission compared to other conventional insecticides. Therefore, detergents can be used safely to control pistachio psyllid. تفاصيل المقالة -

2 - The Effect of Salicylic Acid and Potassium on Some Characteristics Nut and Physiological Parameters of Pistachio Trees Cv. Owhadi
H.R. Karimi S. Sevandi- Nasab H. R. RoostaThe effect of three salicylic acid (0, 50 and 100 mg l-1) and K2SO4 (0, 0.1 and 0.2 %) levels on some characteristics nut and physiological parameters of pistachio trees cv. ‘Owhadi’ were investigated.

Treatments were applied at endospermic growth stage of seed and cotyledons appearance. The results showed that potassium increase yield, splitting percentage; nut fresh mass and kernel dry mass and decrease blank percentage whereas the application of salicylic acid was unaffected on splitting percentage and decrease blank percentage. Simultaneous application of salicylic acid and potassium increase K and Zn concentrations of leaves. تفاصيل المقالة -

3 - The Effect of Salicylic Acid and Zinc on Inflorescence Bud Abscission, Leaf Chlorophyll Florescence and Characteristic of Pistachio Nut Cv. Owhadi
H.R. Karimi S. Sarmadi-Far B. PanahiIn order to determine effect salicylic acid and Zn on characteristics of pistachio nut (Pistacia vera L. cv.

Owhadi), the experiment was carried out as factorial in the framework of CRD design with three replications. The results showed that salicylic acid and Zn increased nut fresh weight and decreased blank nut percentage. The application of salicylic acid decreased splitting percentage and kernel dry weight. Simultaneous application of 250 mg L-1 SA and 0.2% Zn (Zn2SO4) decreased inflorescent bud abscission at compared to control. تفاصيل المقالة
