Abstract

A field experiment was conducted to study the potentiality of different portions of vine and plant growth regulators on growth performance of sweet potato during 2019 and 2020 at vegetable block, College of Horticulture, Munirabad (Koppal), located in the northern dry zone of Karnataka. The experiment was laid out in a Factorial Randomized Complete Block Design (RCBD) with thirteen treatments. Among the two factors, the first factor was different portions of vine for planting consisting basal portion (P1), middle portion (P2) and top portion (P3) and the second factor was plant growth regulators consisting CCC @ 500 ppm (G1), CCC @1000 ppm (G2), Ethrel @ 150 ppm (G3) and Ethrel @ 300 ppm (G4). The control treatments were basal portion of vine (C1), middle portion of vine (C2) and top portion of vine(C3) all without application of growth regulator. Among the different portions of vine used for planting, the top portion of vine recorded significantly higher vine length, Vine inter nodal length, Number of branches per plant and Leaf area. Application of CCC @ 500 ppm was recorded significantly higher growth attributes. The interaction effect of top portion of vine with CCC @ 500 ppm (P3G1) was found to be significantly superior with respect to growth parameters of sweet potato.

Keywords: Interaction effect, leaf area, portions of vine, plant growth regulators, vine length
