摘要

Grape is an important horticultural crop in Iran. Nutritional balance and fertilization are important factors in improving quality and quantities' properties in grape. In order to evaluate the relationship between nutritional balance index (NBI) with yield and quality characteristics of grape, an experiment was conducted in vineyards of Kohgiluyeh and Boyerahmad province during 1996-2000. The aim of this study was to determine nutritional elements' balance status and its effect on yield and quality of vineyards, using the Diagnosis and Recommendation Integrated System (DRIS). The nutritional survey was carried out in 50 vineyards by collecting leaf plus petiole samples. The established norms were used to calculate DRIS indices and nutritional balance index for those vineyards having low yields. Beside, exponential regression analysis was used to evaluate relationship of NBI with yield and quality characteristics of grape. The result showed that a negative and significant (at 1% probability level) relationship existed between NBI and yield. Also, relationship of NBI with sugar, TSS and TSS/TA was negative and for the recent case was significant at 5% probability level. Against these cases, the relationship between NBI and TA was positive but not significant. In addition, based on obtained results, the amount of NBI was higher than expression of imbalanced element in orchards, and that is one of the most important factors of reduction of grape yield and quality.
