Effect of paclobutrazol and pruning on plant growth and yield of mango ( Mangifera indica L.) cv. Langra

Abstract

The optimum use of paclobutrazol is a tool to enable the trees to produce shorter canopy with increased fruit yield during off-season. So, keeping this view the experiment was conducted to study the effect of paclobutrazol and pruning on plant growth and yield of mango (Mangifera indica L.) cv. Langra at experimental area of BAU, Sabour, Bhagalpur, Bihar, India during the two successive seasons 2015 and 2016. The experiment included seven treatments combinations in three replications. The paclobutrazol @ of 1.5 g a.i. per tree was applied in soil drench of mango cv. Langra in March for first year and October for second. The minimum vegetative growth and maximum fruit yield was observed in the pruning method which was soil drenched with paclobutrazol. Thus, light pruning with application of paclobutrazol is able to restrict the canopy growth with enhanced fruit production during the off-season of mango.
