Effect of different level and time of pruning on growth and flowering in Mogra (Jasminum sambac) var. Local

Abstract

An experiment was conducted at Sheth D. M. polytechnic in Horticulture College, Anand Agricultural University, Model farm, Vadodara during 2018-2022 to study the effect of different level and time of pruning in Mogra (Jasminum sambac) var. Local. The study was conducted using randomized block design with factorial concept (FRBD). The treatments comprising of three different time of pruning viz., 2 nd week of November, 2 nd week of December and 2 nd week of January and three level of severity of pruning viz., light pruning (60 cm from the ground level), medium pruning (40 cm from ground level) and heavy pruning (20 cm from the ground level) and compared with control (no pruning). The treatments were applied to two years old plants of Jasminum sambac (L). The result showed that pruning time and level of pruning significantly influence the growth and flowering yield in Jasminum sambac var. Local. Among different pruning time, pruning on 2 nd week of December had most promising result for enhancing vegetative attributes like higher plant height (77.2 and 100.3 at 90 and 180 days after pruning), length of secondary shoot (32.36 cm), number of leaves per secondary shoot (20.61), plant spread N-S (51.44 cm), plant spread E-W (54.72 cm), number of secondary shoot per plant (29.32) and yield (6.02 t/ha) in Jasminum sambac var. Local. While, in case of severity of pruning, medium pruning (40 cm from the ground level) recorded significantly higher plant height (107.2 cm at 180 days after pruning), length of secondary shoot (34.91 cm), number of leaves per secondary (20.79) shoot and number of secondary shoot per plant (28.58) and yield (5.83 t/ha). Pruning of Jasminum sambac var. Local at 40 cm above ground level during second week of December is beneficial for better growth and flowering yield.
