A field experiment was carried out in Horticulture Research Farm, Bidhan Chandra Krishi Vishwavidyalaya, Mohanpur, to study the effect of paclobutrazol as foliar spray at different dates, on growth, flowering and bulb yield of tuberose (Polianthes tuberosa L.) var. Prajwal. The experiment was carried out during the year 2016-2018 (March - March) to find out the suitable dose of paclobutrazol and amicable time of its spraying, to get maximum flower production. The experiment was laid out in augmented factorial randomized block design with three replications. The first factor contains three different doses of Paclobutrazol application P1 (100 ppm), P2 (200 ppm), P3 (300 ppm) as foliar spray and the second factor is with three different times of Paclobutrazol application i.e., S1 (45 DAP), S2 (65 DAP), S3 (85 DAP). A control plot is made without any application of paclobutrazol to observe the difference in the treatment effect. Combining the two year data, the pooled data reveals that, the self-life of spike and the weight of spike was observed maximum with the application of 200 ppm paclobutrazol at S2 (65 DAP) respectively. While the vase life of spike and floret diameter was observed maximum with the application of 300 ppm paclobutrazol at S2 (65 DAP). It can be concluded that, the quality flowers of tuberose var. Prajwal could be observed with the application of paclobutrazol @ 200 ppm at 65 days after transplanting (DAP).
