Cockscomb is an ornamental plant that withstands moderate temperature and moisture during the summer season. The aim of this study is to investigate how plant growth regulators can alleviate stunted growth and flower head drop in celosia, a common issue affecting its development. This study checked the effect of foliar application of GA3 and SA on Celosia. Different concentrations of GA3 50 mgL-1, 100 mgL-1, 150 mgL-1 and SA of 50 mgL-1, 100 mgL-1, and 150 mgL-1 was used. There was total seven treatments and each treatments was replicated three times. Complete Randomized Design was used to organize the experiment. Data was collected for different morphological parameters, physiological and anatomical parameters. Recorded data showed that T2 GA3 (100 mg/l) showed maximum plant height (99.66 cm), number of leaves (89.66 count), plant stem diameter (28.10 cm), leaf area (29.5 cm2), fresh mass of flower (101.93 g), dry mass of flower (97.55 g), flower quality (9), total chlorophyll content (23.93), SOD (1.05), POD (0.41), abaxial stomata density (2015.3 µm2), adaxial stomata density (2914 µm2), lamina thickness (296.84 µm), lamina thickness (656.32 µm2), adaxial stomatal area (456.63 µm2), abaxial stomatal area (530.4 µm2), number of vascular bundles (36.66 count), phloem area (275.51 µm2), and meta xylem area (623.93 µm2) as compared to all other treatments. It is concluded that that GA3 foliar spraying is an effective approach to enhance the quality and productivity of Celosia.
