This could impact the production and quality of grapevine (Vitis vinifera L. cv. Karaerik). A field experiment was conducted for determining the optimum economic B rate (OEBR), critical soil test, and tissue B values for yield and quality response of grapevine to B fertilizer application method (foliar and soil) at 5 doses (0, 1, 3, 9, and 12 kg B/ha) for 2 years. OEBR of foliar and soil application ranged from to kg B/ha with an average yield of – t/ha, respectively. The average soil B content at the OEBR was – mg/kg. Leaf tissue B content amounted to and mg/kg, and berry B content amounted to and mg/kg for foliar and soil application methods, respectively. Independently of application method, B application increased tissue N, Ca, Mg, P, K, and Zn, yet decreased Fe, Mn, and Cu content. We concluded that a B addition of kg/ha for foliar application and kg/ha for soil application is sufficient to elevate soil B to nondeficient levels. Key words: Aridisol, boron deficiency, macro and micronutrient, optimum economic yield 1. Introduction Boron (B) is very important for the healthy .
