Effect of foliar application with nitrogen, boron, zinc, and summer pruning on fruit set and fruit ‎quality and quantity of grape (Vitis vinifera cv. Siah Shahani) in Pasargad, Fars’s province. The highest leaf length (22.3 cm) was observed in the control treatment and green pruning. The leaf width (11.1 cm) were observed in the nitrogen treatment. The combination of zinc and green pruning created the longest cluster length (33.9 cm) and the combination of zinc + nitrogen + boron and green pruning created the highest number of berries (170). The interaction of zinc + nitrogen and green pruning and green pruning, respectively, caused the highest number of berries (217.2) and the volume of berries (119 ml). The highest number of seeds (55.5) was related to the treatment of nitrogen + boron and green pruning combination. The highest wet weight (1.7 g) and seed size (4.98 mm) were observed in the treatment of boron. Most chlorophyll (34 mg g^-1 dry weight) was observed in the zn and boron spray treatment. The use of fertilizer treatments did not have a significant effect on pH and TSS, but the use of nitrogen + boron and green pruning significantly increased vitamin C levels compared to control.
