Abstract: The current investigation was carried out at the Department of Floriculture and Landscape architecture during 2022-24 to assess the plant growth, flower yield and flower quality of nine budded clone of Jasminum sambac under two pruning regimes (two and three pruning per year) with different levels of NPK fertilizers (eight treatments). The experiment was laid out in FRBD and replicated thrice. The results revealed that the highest plant height (98.45cm) , no. of primary branches (22.00), no. of secondary branches (45.77), maximum plant spread (80.54 cm2 (EW),78.54 cm2 (NS)), increased number of leaves per plant (1196.11), earliest days taken for flowering (28 days), increased no. of cymes per plant (2715.70), number of flower bud per cyme (7.92),  100 flower weight (34.30 g) and flower yield per plant (1105.00 g) was obtained from the treatment P3F2 with three prunings per year along with 75:150:150 g of Urea, SSP, MOP/ plant/ year. Likewise the treatment P3F2 (Three pruning + 75:150:150 g of Urea, SSP, MOP/ plant/ year) and P3F3 (Three pruning + 75:180:150 g of Urea, SSP, MOP / plant/ year) resulted in superior value for concrete content (0.26%).
