This investigation was carried out in a commercial orchard in Ashtian city, Markazi province. The effect of N-phenyl-phthalamic acid and nutrition on fruit quantity and quality of plum cv. Maragheh was studied with the aim of increasing yield. The N-phenyl-phthalamic treatments (concentrations, 0, 500 and 1000 mg/l) were performed at full bloom (80 % flowering) on 29 March. Also, nutrition was conducted on 18 May using perfect liquid fertilizer (Plant Green). As a result of this process, the yield amount was increased, when N-phenyl-phthalamic acid 500 and 1000 mg/l treatment were used without fertilization comparison to control. But fruit quality parameters (weight, length, and width) were decreased in comparison to control. However, treatments N-phenyl-phthalamic acid 500 and 1000 mg/l with fertilization not only increased fruit setting but also increased fruit quality characters (weight, length, and width). According to the present results, N-phenyl-phthalamic acid (500-1000 mg/l) along nutrition can be used for the improvement of fruit quantity and quality of plum.
