Abstract: An investigation on “Effect of plant growth regulator on growth, yield and quality parameters of calendula (Calendula officinalis L.) var. Fiesta Gitana under Telangana conditions” was carried out in the research field of the Department of Floriculture and Landscaping, College of Horticulture Rajendranagar, SKLTSHU during the year 2024. The purpose of research was to observe the effect of different concentrations of Gibberellic acid (150, 200 ppm), Salicylic acid (100, 150 ppm), Cycocel (1000, 1500 ppm) and Alar (B-9) (500, 1000 ppm) in calendula plant growth attributes, yield attributes and quality attributes. The results revealed that maximum plant height (48.96 cm), flower diameter (6.40 cm), stalk length (7.61 cm) and Maximum flower longevity (12.86 days) were noted under GA3@ 200 ppm and the maximum plant spread (45.90 cm), leaf area index (4.17), internodal length (6.40 cm), days taken to first bud initiation (52.58), days taken to 50% flowering (58.85), days taken from bud to full blooming (4.00), days taken to first harvest (65.56), Fresh flower weight (6.82 g), number of flowers per plant (27.75 days), number of pickings (4.66), flower yield per plant (189.27 g), flower yield per plot (3.79 kg), flower yield at end of experiment (11.37 kg), flower yield per hectare (189.60 quintals). In research, control was reported minimum for every trait from different concentrated PGRs taken in the investigation.
