Analysis of Bio- Stimulant Effectiveness for Improved Phenotypic Attributes and Post - Harvest Life of Asiatic Lily cv. Indian Summerset

The study was conducted at the Research Farm at Department of Horticulture, Sam Higginbottom University of Agriculture, Technology, and Sciences in Prayagraj during the years 2021-22 and 2022-23. The experiment involved thirteen treatments namely triacontanol at concentrations of 10ppm, 15ppm, 20ppm, and 25ppm, brassinolide at concentrations of 5ppm, 10ppm, 15ppm, and 20ppm and nitrobenzene at concentrations of 100ppm, 200ppm, 300ppm, and 400ppm, organized in Randomized Block Design with three replications. These treatments were applied twice at fifteen-days interval. The result revealed that T5 - triacontanol @ 25 ppm demonstrated the most favorable outcomes concerning plant height (63.3 cm), number of leaves per plant (62.6), leaf area (14.9 cm2), and diameter of shoot (12.9 mm) while T9 - brassinolide @ 20 ppm marked longer vase life (9.8 days).
