Abstract: An experiment was conducted to study the effect of chemicals and colour shade nets on growth of epicotyl grafting of mango (Mangifera indica L.) cv. Kesar at Regional Horticultural Research Station, ASPEE College of Horticulture & Forestry, Navsari Agricultural University, Navsari during the year 2017-18. The experiment was laid out in completely randomized design with two factors repeated three times. The treatment comprised of 3 different chemicals as scion dip viz., No application of chemical (C1), BAP @ 20 mgl-l for 5 second (C2) and BAP (20 mgl-l) +ZnSO4 (750 mgl-l) (C3) for 5 second and five different colour shade nets viz., open field condition (P1), green colour shade net (P2), red colour shade net (P3), white colour shade net (P4) and blue colour shade net (P5). Results of present investigation revealed that the scion treated with BAP 20 mgl-1 + ZnSO4 750 mgl-1 for 5 seconds (C3) was found better for early sprouting, graft sprouting percentage, number of graft success and survival percentage, number of leaves, total leaf area, root length and number of roots and fresh and dry weight of roots. Whereas, BAP @ 20 mgl-1 for 5 seconds (C2) was found beneficial for incremental height of graft, incremental girth of scion and fresh and dry weight of shoot. Among the different colour shade nets, mango epicotyl grafts kept under green colour shade net (P2) was found effective with respect to graft success parameters (days taken for sprouting, graft sprouting percentage, number of graft success and survival percentage and shoot parameters viz., incremental height of graft, number of leaves, total leaf area, fresh and dry weight of shoot. Similarly, root parameters (number of roots, root length, fresh and dry weight of roots) were also found superior in green colour shade net. While, girth of scion was found maximum under red and compared to other colour shade nets. Considering the interaction effect between chemicals and colour shade nets, maximum fresh and dry weight of shoot and root length were found when scion treated with BAP 20 mgl-1 for 5 seconds and grafts kept under green colour shade net (C2P2) at 6 months after grafting. While, maximum number of leaves and total leaf area were recorded with the C3P2 and C1P2 treatment combinations, respectively at 6 months after grafting.
