Abstract

Nutritional balance is an important factor in increasing the YIELD and improving the quality of orchard production. The DRIS system is a suitable method for determining the NUTRITIONAL BALANCE status of orchards using leaf analysis. In order to recognize nutritional disorders in vineyards, a four-year (1997-2000) field experiment was conducted in Kohgiluyeh va Boyerahmad province. For this purpose, leaf analysis data from high yielding orchards were used to establish DRIS norms for GRAPEvines. The norms obtained for N, P, K, Ca and Mg were 5.05, 42.7, 1.42, 1.7 and 0.4 percent in leaf dry matter and for Fe, Mn, Zn, Cu and B were 206.5, 110.3, 61.5, 14.6 and 33.9 mg/kg, respectively. The established norms were used to calculate DRIS indices and NUTRITIONAL BALANCE index(NBI) for those orchards having low yielding. The results showed that mineral nutrients were imbalanced in low- yielding orchards and Fe, Cu, Mn, N, K, Zn, B and P deficiencies were in 56, 56, 53, 44, 44, 41, 41, and 41 percent of this orchards, respectively. Based on the results, relative nutrient demands in low yielding orchards were obtained: Cu>Fe>P>Mn>Zn>N>Mg>K=B>Ca.
