Pruning and defoliation of older leaves are the two important factors that determine the floriferousness in jasmine. Hence an experiment was planned on combined effects of pruning and defoliating chemicals on growth and flower yield in jasmine (Jasminum sambac L.) in a commercially important variety Gundumalli to find out the pruning severity and effective defoliating chemical for enhanced flowering. The experiment was conducted on 8 years old jasmine plants with three pruning levels (pruning to 75 cm above the ground level, pruning to 50 cm above the ground level and no pruning) and three defoliating chemicals (5 % potassium nitrate, 1 % sodium chloride, water spray). Pruning of jasmine plants to 50 cm height above the ground level and foliar application of 5 % potassium nitrate (KNO3) seems to be beneficial for jasmine to enhance nutritional status of plant, improve the vegetative growth, initiating early flowering, & long duration of flowering & increase the productivity.
