Abstract: In the present investigation, 50% vegetative growth on terminal shoots were pruned during mid-August and mid-September on 22 varieties of guava in a factorial design in Bidhan Chandra Krishi Viswavidyalaya’s Horticultural Research Station, West Bengal, during 2018-2019 to investigate the impact of shoot pruning on reproductive as well as yield characteristics of guava. According to experimental findings, minimum days for axillary bud emergence (10.33 days) was observed in Safed Jam pruned during August, maximum number of axillary bud (27.00) emerged in SRD-1 pruned during August. Maximum number of sprouted bud (22.33) sprouted in China pruned during September. Minimum days for flower bud emergence (63.33days) was recorded in Kohir Safeda pruned during August. Maximum fruit set percentage (85.14%) recorded in Hissar Surkha and Kafri pruned during August. Finally, it can be concluded that 50% shoot pruning in months of August and September successfully promote vegetative as well as reproductive growth of guava.
