Standardization of grafting month and growing conditions on softwood grafting in mango (Mangifera indica) cv. Kesar

Abstract

An investigation on “Standardization of grafting month and growing conditions on softwood grafting in mango (Mangifera indica) cv. Kesar” was carried out at Department of Fruit Science, Kittur Rani Channama College of Horticulture, Arabhavi, Karnataka during the year 2023-24. The treatments comprised of three levels of growing conditions (C) viz., C1 = Partial shade, C2 = Shade house condition, C3 = Naturally ventilated polyhouse (NVP) and five levels of different grafting months (M) viz., M1 = September, M2 = October, M3 = November, M4 = December, M5 = January. The experiment was laid out in Completely Randomized Design (CRD) with Factorial concept comprising fifteen treatment combinations with three replications. The results revealed that among the different treatment combinations grafting done in September under polyhouse conditions required minimum days for first sprouting (15.42). Whereas, C3M1 (15th September and Polyhouse condition) recorded the maximum number of sprouts per graft (5.41), sprout length (7.42 cm), number of leaves (20.20), graft height (47.12 cm), graft vigour index I (694.82 cm) and graft vigour index II (4513.34 cm) at 120 days after grafting respectively. While, maximum graft success percentage (93.33%) was recorded at 90 days after grafting and maximum graft survival percentage (89.17% and 85.83%) was recorded at 120 and 180 days after grafting respectively.
