Abstract: In due course of time very old trees are becoming senile and unproductive. In order to mitigate this problem, an experiment on “Effect of Different Level of Pruning on Growth, Yield and Fruit Quality of Sapota cv. Cricket Ball under Coastal Zone of Odisha” was carried out at central farm, College of Agriculture, Orissa University of Agriculture & Technology, Bhubaneswar during the year 2013-2016. Trees were prune in five different levels followed by five different type of hormone were sprayed on 55 year old trees. The experiment was laid out in Split plot Design in which pruning was under main plot whereas spraying of plant growth hormones were kept in sub-plot. Trees were pruned in 2013 and at regular interval different growth observations like tree canopy spread and leaf chlorophyll content; yield contributing characters like Fruit set percentage (%), Days required from flowering to harvesting, Fruit yield (kg/plant), Fruit volume (cc), Fruit weight (g) and Physico-chemical quality of fruit like Total soluble solids (°Brix), Acidity (%), Total sugar content (%), Fruit moisture (%) and pH of fruit were taken under study. Initial two year there was no yield observed in the primary and secondary branch pruned plant. During the investigation period, maximum yield was obtained in tip clipped of terminal shoot (P2). With increase in level of pruning, yield decreased but fruit volume, fruit weight and fruit set % were increased. Highest total sugar, TSS were recorded in treatment P5 (1o branched pruned tree) whereas highest Titrable acidity was found in unpruned tree (P1). Both moisture % and pH of ripe sapota fruit were non-significant to different level of pruning.
