Influence of time and level of pruning on flowering yield in Jasminum sambac var. Baramasi under South Gujarat condition

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 flower yield per plant (1076.14 g), flower yield per plot (4.33 kg) and flower yield per hectare (6.91 t) in Jasmine plants. Among the various pruning levels, pruning done at 50 cm from the ground level (L2) was most significantly influenced flower yield (1116.28 g/plant, 4.47 kg/plot 6.69 t/ha). In case of interaction effect of different pruning time and pruning level was found significant with respect to yield traits. Plants pruned in second week of December at 50 cm above ground level (T2L2) produced significantly maximum flower yield (1216.20 g/plant, 4.91 kg/plot and 8.12 t/ha). Based on the results of the present investigation, pruning of Jasminum sambac var. Baramasi at 50 cm above ground level during second week of December is beneficial for better flowering yield of jasmine flowers.
