Abstract:
The present study was carried out at Horticultural Research Field, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during the summer season of 2021. The experiment was laid out in Randomized Block Design with twelve treatments and three replications. Twelve different levels of N, P, K were studied in this investigation. The study revealed that all the characters were significantly affected by the combination of N, P, K fertilizers. On the basis of present investigation it is concluded that, the application of T₉ N, P, K (45, 35, 45) (g/m²) treatment was found to be the best in terms of plant growth and flower yield viz., plant height (49.42 cm), number of leaves per plant (59.63), number of branches per plant (10.82), plant spread (34.86 cm²), days to emergence of 1^st flower bud (31.61 days), days to opening of 1^st flower (37.86 days), flower diameter (8.04 cm), flower weight (6.52 g), no. of flower per plant (12.52), no. of flower per plot (75.14), flower yield ha^-1 (7.51) and vase life (6.83 days) of Zinnia elegans. Therefore, application of T₉ N, P, K (45, 35, 45) (g/m²) on zinnia plants can be recommended for better growth and flowering under Prayagraj agro-climatic condition.
