Shoot tip pruning and paclobutrazol soil drench on the yield of mango hybrid Ratna under HDP system
Abstract
A study on the effect of tip pruning of shoots at two pruning levels (10 cm and 20 cm) with and without paclobutrazol application on the yield parameters of mango hybrid Ratna was conducted in the mango orchard attached to the Department of Fruit Science, College of Agriculture, Vellanikkara during 2018- 2019. Seventeen treatments (T1 -T8 consisted of pruning at 10 cm and 20 cm length from the tip of the shoot during June, July, August and September, T9 -T16 consisted of pruning at 10 cm and 20 cm length from the tip of the shoot along with paclobutrazol soil drench during June, July, August and September months and T17 as the control) with two replications were carried out following completely randomised block design (CRD). Pruning all the shoots of the tree to a length of 20 cm from the shoot tip along with paclobutrazol soil drench during June month was observed to produce maximum number of fruits per tree and maximum fruit yield (kg/tree) in Ratna. The individual fruit weight was maximum in the trees pruned at 20 cm length during September month drenched with paclobutrazol.Downloads
