Abstract: An investing on flowering behaviour of Jasminum sambac L var. Local influenced by time and severity of pruning was conducted at Sheth D. M. polytechnic in Horticulture College, Anand Agricultural University, Model farm, Vadodara during 2018-2022. The treatments under study were analysed by randomized block design with factorial concept (FRBD). The treatments included three different pruning time viz., 2^nd week of November, 2^nd week of December and 2^nd week of January and severity of pruning in three levels 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). Two years old plants of Jasminum sambac (L) were selected for experiment. The result showed that pruning time and level of pruning significantly influence the flowering parameters in Jasminum sambac var. Local. Pruning on 2^nd week of December had most promising result for enhancing flowering attributes viz., flower diameter (3.69 cm), weight of 100 flowers (49.23 g), flower per plant (866.42 g) and estimated yield (6.02 t/ha) while significantly lower days to flower bud initiation (43.29 days), days to 50% flowering (54.53 days) and total numbers of flowering days (138.76 days) were found in Jasminum sambac var. Local pruned on 2^nd week of January. Whereas, in case of severity of pruning, medium pruning (40 cm from the ground level) recorded significantly lower days to flower bud initiation (48.30 days), days to 50% flowering (55.69 days) and total number of flowering days (139.82 days) and significantly higher flower diameter (3.77 cm), flower per plant (840.06 g) and estimated flower 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.
