The effect of various combination of macro (N, Mg, and K) and micronutrients (Fe and Zn) on yield, fruit quality, and tissue mineral concentrations of an important commercial table grape cultivar (Vitis vinifera cv. Bidaneh Qermez) was studied over three growing seasons of 1999 - 2001. Yield, fruit set, cluster weight, cluster number, berry size and quality attributes (soluble solid concentrations, pH, K-skin) were influenced by N, K, Mg, Fe, and Zn applications. Potassium application increased cluster number and weight, which resulted in a significant increase in the yield. Potassium influenced berry quality attributes more than other applied mineral elements. Yield was positively correlated to the soil total N at 30 - 60 cm depth. Nitrogen application increased growth of the main and lateral canes. Soil N did not correlate strongly with tissue N status.
