Abstract

Studies on the effect of plant density on vine growth, nutrient status, yield and quality of the grape cv. Perlette were carried out during 1980, 1981 and 1982. Vine growth measured in terms of shoot length, trunk girth and pruning weight as weil as the level of the nutrient elements N, P, K, Fe, Mn, Zn and carbohydrates were highest at the maximum spacing i. e. 3.0 x 3.0 m and decreased with an increase in the plant density. Most of the nutrients were high either in early spring or during the rainy season. The average yields per vine and per ha were highest at 3.0 x 3.0 m and 2.0 x 2.0 m spacing, respectively. No significant differences were observed in the various quality parameters of the fruit under various plant densities. Under the prevailing agro-climatic conditions optimum yield per ha of Perlette grapes trained on head system can be obtained by planting the vines at 2.0 x 2.0 m spacing.
