abstract
The present investigation was carried out at Agricultural Research Farm, in the Department of Horticulture, School of Agriculture, at Suresh Gyan Vihar University, Jaipur (Rajasthan) during 2023-24. The experiment was laid out in Factorial Randomized Block Design which comprises of nine treatment combinations viz; Control (T₀), calcium @ 50 ppm (T₁), calcium @ 100 ppm (T₂), NAA @ 25 ppm (T₃), NAA @ 50 ppm (T₄), calcium @ 50 ppm + NAA @ 25 ppm (T₅), calcium @ 50 ppm + NAA @ 50 ppm (T₆), calcium @ 100 ppm + NAA @ 25 ppm (T₇), and calcium @ 100 ppm + NAA @ 50 ppm (T8) treatments were replicated three times. The various concentrations of calcium and NAA had significant effect on various vegetative growth, yield and quality parameters and maximum (38.65 cm), (52.99 cm) and (73.55 cm) plant height, (8.86), (15.53) and (16.75) branches per plant and (47.59), (92.83) and (102.23) leaves per plant at 45, 60 and 75 DAT, respectively, minimum (39.13 days) took for 50% flowering, maximum (11.81) fruits per plant, highest (130.68 g) fruit weight, highest (1551.63 g/plant) and (43.10 t/ha) capsicum yield, maximum (131.51 mg/ 100 g) vitamin – C, net return (₹. 4, 02, 291.64/ha) and highest B: C ratio (4.31) were recorded under foliar application of calcium @ 100 ppm + NAA @ 25 ppm treatment.
