Abstract


The objective of the current study was to investigate the effect of soil and foliar application of some fertilizers on the yield and quality of table grapes cv. Alkdarri. Soil and foliar fertilizer application treatments included a control, Ca 200 g/vine, K 150 g/vine, N 200 g/vine, Ca 30 g/L, grow more INC fertilizer 10 g/L, K 20 g/L, and Cu 5 mg/L. Results indicate that soil and foliar fertilizer application increases quality and quantity of table grapes compared to control treatment. The highest berry diameter, a weight of 100 berries and a size of 100 berries were obtained in vines treated with Ca 200 g/vine, using the soil application method. The highest cluster weight was obtained in vines that were treated with K 150 g/vine, using the soil application method. The highest berry firmness was obtained in vines that were treated with K 20 g/L using the foliar application method. The highest pH and TSS were obtained in vines treated with Cu 5 mg/L, using the foliar application method. The highest fruit yield was found in vines that were treated with 150 g K.
