Abstract:
The field experiment was conducted in nethouse during Rabi, 2022 at AICRP on Seed (Crops), NSP, UAS, GKVK, Bengaluru, to study the effect of foliar application of plant growth regulators on crop growth and seed yield of paprika chilli. The experiment consists of 12 different plant growth regulators with paprika chilli variety OAL-1 planted in RCBD with 3 replications. Significant differences were noticed between the treatments for crop growth and seed yield parameters. Among the treatments, crop sprayed with Homobrassinolide @ 0.6 ml/l (T₆) recorded higher growth and yield parameters viz., plant height at harvest (106.56 cm), number of branches per plant at harvest (17.03), fruit length (15.22 cm), number of fruits per plant (25.79), fruit yield (39.56 q/ha), number of seeds per fruit (63.65), seed yield (333.54 kg/ha) compared to control (78.56 cm, 12.27, 11.86 cm, 20.17, 28.63 q/ha, 51.52, 242.55 kg/ha), respectively. Highest B:C ratio (2.64) was noticed with Homobrassinolide @ 0.6 ml/l compared to control (1.92).Hence, it can be concluded that spraying of Homobrassinolide @ 0.6 ml/l at 30, 60, 90 DAT could be employed to enhance crop growth and seed yield of paprika chilli.
