The present investigation entitled “Comparative studies on top working techniques for bud wood production in apple (Malus Ñ… domestica Borkh.)” was carried out in the Department of Fruit Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) India in 2019-2020. The experiment was laid out in Randomized Block Design consisting of eleven treatments replicated thrice. In this experiment, three grafting methods viz., tongue, cleft and bark performed at 1 m, 1.25 m and 1.5 m height in combination with two budding methods viz., T-budding and chip budding done at 1 m height were used for top working. The results revealed that the highest graft take success (93.27 %), total number of shoots (49.67), number of secondary shoots (30.67), annual primary shoot extension growth (182.00 cm), annual secondary shoot extension growth (112.00 cm), average annual shoot extension growth (147.00 cm), number of buds (57.80), number of leaves (59.59), total chlorophyll content (2.89 mg/100g), diameter of graftable shoots (7.75 mm), number of graftable shoots (248.00) and per cent graftable scion wood (52.73 %) were recorded in the plants top worked with tongue grafting at 1.25 m height. Whereas, diameter of shoots (> 8 mm) i.e. 17.35 mm and number of shoots (> 8 mm) i.e. 164.00 were found to be highest in the plants top worked with cleft grafting at a height of 1 m. Therefore, tongue grafting at a height of 1.25 m resulted in maximum bud wood production for top working in apple.
