An experiment was conducted to assess the differential responses of Boron and Calcium on the growth and flowering of Lisianthus during the period from January to May 2024 at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The experiment was conducted with a Complete Randomized Design (CRD) with three replications. Collected data on growth and flower yield attribute parameters showed significant variations. According to the results, the maximum plant height (17.54 cm), stem length (42.7 cm), Number of leaves (77.33), Stem diameter (2.19 cm), Plant spread (23.89 cm), Number of branches (3.00), leaf area (12.76 cm²), SPAD value (67.50), Number of days to taken initiation (123), bud no./plant (11.00), Bud length (2.39 cm),Stalk length(19.44 cm) and number of flower per plant(3.61) were found from the Ca treated plants. The treatment T₈ - Calcium @100 ppm was found superior among other treatments.
