Abstract

Pruning had a significant effect on the tree height, tree spread and canopy volume were affected significantly by various pruning/spacing treatments severity of pruning results in decrease of tree height, tree spread and tree canopy volume and fruit yield. In rainy season, fruit yield was the highest in control trees at 6x5 m spacing, while in winter season maximum fruit yield per tree was obtained in pruning treatment by removal of 1/3rd vegetative growth at 6x5m spacing. However total fruit yield and yield t/ha of both rainy and winter seasons was maximum in pruning treatment by treatment by ½ removal of vegetative growth at 6x4m spacing. Fruit quality adjudged on the basis of high fruit weight (g), palatability rating, TSS (%), total sugars and vitamin –C (mg/100 fruit pulp) and low acidity was the best in pruning treatment by ½ removal of vegetative growth at 6x4m spacing.
