Grape is the most commercially valuable crop in India and it is consumed as fresh table grapes and its juice; and processed raisins and its wine. The cultivars of wild and table grapes are evolved over centuries and possess distinct plant phonology, nutrient requirements and finally, the fruit quality. A study was conducted to compare the nutrient use efficiencies in wine and table grapes. Application of three major nutrients was found significantly higher in table grape vineyards in contrast to wine grape orchards. The fresh grape yields of wine and table grapes varied significantly. The wine grape yields were lesser with a mean yield of 12.0 ± 1.2 t ha-1. In contrast, table grape yields were higher with mean yield 24.0 ± 1.50 t ha-1. Productivity of grapes per unit of applied N, P and K nutrients were derived using total individual nutrients added and the corresponding yields. It was interesting to observe that the productivity –nutrient ratios of table grapes were found to be significantly higher while, wine grape orchards recorded lower productivity-nutrient ratios. The cost-benefit ratios were found to be 1.44 and 1.57 for wine and table grapes respectively.
