Abstract: The present investigation was conducted at Floriculture Research Farm, Navsari Agricultural University, Navsari (Gujarat) during the year 2016-17 under a Randomized Block Design with Factorial concept (FRBD) along with nine treatment combinations consisting three pruning time i.e. last week of November, second week of December and last week of December and three different levels of pruning i.e. 25 cm, 50 cm and 75 cm from the ground level. The treatments were repeated thrice. Different pruning time and pruning level influenced significantly on vegetative and flowering characters in Jasminum sambac. Among the various pruning time, 2nd week of December had most striking influence in enhancing the vegetative attributing characters viz. incremental plant height at 60, 120 and 180 days, (87.32, 95.90 and 112.94 cm, respectively), length of primary shoot (52.76 cm), number of leaves on primary shoot (66.72) and plant spread in E-W and N-S (92.45 and 94.88) as compared to the other treatments. Superiority of flowers with respect to flower bud length (3.41 cm) and flower bud diameter (1.00 cm) was recorded in plants pruned in second week of December, whereas, the traits such as minimum days taken for first bud initiation, commencement of flowering (43.93 and 53.38 days, respectively) and the weight of hundred flower buds (33.42 g) were noticed in plants pruned on last week of December. Among the various pruning levels, pruning done at 75 cm from the ground level was most significantly influenced vegetative attributing characters viz. incremental plant height at 60,120 and 180 days (106.97, 115.05 and 118.64 cm respectively) and plant spread in E-W and N-S (106.38 and 106.93 cm) directions as compared to the other treatments. However, the length of primary shoot at 60 days (59.02 cm) and maximum number leaves per primary shoot (84.98) were found in bushes pruned at 50 cm from the ground level. Flower bud length (3.46 cm), flower bud diameter (1.04 cm) and weight of hundred flower buds (33.42 g) were highest in the plants pruned at 50 cm above the ground level, whereas early flower bud initiation (42.15 days) and commencement of flowering (51.93 days) were noticed in the plants pruned on last week of December. In case of interaction effect of different pruning time and pruning level was found non-significant with respect to all vegetative growth and flowering traits. Pruning of Jasminum sambac var. Baramasi at 50 cm above ground level during second week of December is beneficial for better growth and flowering with good quality of jasmine flowers.
