Abstract: A field experiment was carried out during kharif2016-17 at Kittur Rani Channamma College of Horticulture, Arabhavi (Karnataka) to study the effect of growth regulators on growth parameters of sweet potato [Ipomoea batatas (L.) Lam.]. The results revealed that the spraying of GA3 @ 100 ppm (T3) showed significantly highest Vine length (125.50 cm), Petiole length (26.83 cm) and Significantly highest leaf area (87.43 cm2) was recorded with the combination of GA3 100 ppm plus CCC 250 ppm (T10), which was on par with GA3 at 100 ppm (85.18 cm2),
Keywords: sweet potato, plant growth regulators, growth parameters
