Enhancing the yield and quality parameters of polyhouse grown hybrid sweet pepper by using plant growth regulators

Author(s): Mallikarjun Dhotre, SM Mantur, MS Biradar and SM Hiremath
Abstract: The yield and quality parameters of sweet pepper as influenced by plant growth regulators and their spraying intervals were studied. The experiment was laid out in factorial design with six growth regulators and three spraying intervals as well as one absolute control making 19 treatment combinations. The results revealed that, CCC @ 600 ppm (G6), CCC @ 400 ppm (G5) and NAA @ 100 ppm (G2) resulted in significantly higher fruit yield (2.17, 2.14 and 2.13 kg/plant). The chemical and nutraceutical parameters of sweet pepper fruits were significantly improved by the application of plant growth regulators. The higher dose of plant growth retardant CCC @ 400 and 600 ppm resulted in higher TSS (5.50 and 5.44 0Brix, respectively). However, NAA @ 100 and 150 ppm considerably increased the amount of Asocrbic acid (137.53 and 130.84 mg/100 g, respectively) and total dietary fibres (2.99 and 2.94 %, respectively) in sweet pepper fruits. The effect of growth regulators increased significantly with the spraying intervals. Compared to control (1.74 kg/plant), the fruit yield was significantly higher under the combinations of NAA @ 100 ppm sprayed at 4 intervals (2.42 kg/plant) CCC @ 600 ppm sprayed at 4 intervals (2.39 kg/plant) and the same interactions outperformed control with respect to TSS, ascorbic acid and dietary fibre components in sweet pepper.
