Effect of Major Nutrients (N:P:K) on Plant Growth and Flower Yield of Jasmine (Jasminum auriculatum)

The present investigation entitled, “Effect of major nutrients (N:P:K) on Plant growth and Flower yield of Jasmine (Jasminum auriculatum)” was under taken in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (Allahabad) during 2021-2022. The experiment was layout in Randomized Block Design (RBD) with 09 treatments and each treatment replicated thrice. The treatments consist of different combinations of Chemical fertilizers (N, P and K). The treatment T8 (120:120:120g N:P:K/plant) was found the statistically significant compared to other treatment combination, which recorded highest plant height (92.44 cm), plant spread (61.82 cm), Number of leaves (142.77), Number of branches (16.29), followed by T6 (90:180:180g N:P:K/plant) and lowest growth by T2 (30:60:60g N:P:K/plant). The treatment T9 (120:240:240g N:P:K/plant) was found the statistically significant compared to other treatment combination, which recorded least days for flower bud development (14.25 days), days to first flower bud initiation (219.92 days), duration of flower (5.56 days), flower bud diameter (26.20 mm), flower bud length (2.16 cm), weight of single flower bud (0.198 g), flower yield per ha. (2.54 tons.) followed by T7 (105:210:210g N:P:K/plant).
