Abstract:
The present investigation “Response of GA3 and Paclobutrazol on vegetative growth and yield attributes of Tuberose (Polianthes tuberosa L.)” was carried out in Horticulture Research Farm at the Department of Floriculture and Landscape Architecture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C. G.) in the year 2017-18 and 2018-19. The experiment was laid out in Factorial Randomized Block Design with three replication and sixteen treatment combinations of two plant growth regulator namely GA3 150 ppm (30 and 50 DAP) and paclobutrazol 10 ppm (70 DAP) were taken as growth promoter and growth retardant, respectively. And two cultivars namely prajwal (V1) and bidhan ujjwal (V2). In case of variety, the maximum plant height, length of leaf, number of leaves plant-1, fresh dry weight of leaves (g), dry weight of leaves (g) and yield (q ha-1) was recorded with cv. Prajwal (V1) as compared to cv. Bidhan ujjwal (V2). The results investigate the effect of different levels of growth promoter and retardant on growth, flowering and yield of different cultivars of tuberose. Among the different treatment of PGRs the significantly maximum plant height, length of leaf, number of leaves plant-1, fresh and dry weight of leaves (g) were observed with application of GA3 150 ppm (30 and 50 DAP) during both the years. Whereas, significantly maximum yield of bulbs (q ha-1) were recorded with application of GA3 150 ppm (30 and 50 DAP) + Paclobutrazol 10 ppm (70 DAP) during both the years.
