Abstract: A study was carried out to know the effects of high density planting and paclobutrazol on growth and yield of mango (Mangifera indica L.) cv. Alphonso at Regional Horticulture Research and Extension Centre, Dharwad (University of Horticultural Sciences, Bagalkot) during May - 2016 to June – 2018. The maximum incremental data of plant height (18.48 cm) and plant spread East- West increment (18.65 cm) were recorded in D1P1 (2.5 x 2.5 m spacing with control plants). The treatment D4P2 (7.5 x 5.0 m spacing with 2 ml paclobutrazol) recorded the maximum plant girth (1.17 cm), tertiary branches (25.67), number of fruits per plant (53.24) and yield per plant (13.71 kg) whereas, the treatment D4P1 (7.5 x 5.0 m spacing with untreated plants) recorded the maximum canopy volume (0.88 m3). The treatment D4P1 (7.5 x 5.0 m spacing in control) recorded the maximum plant spread North- South (17.84 cm) whereas, the highest number of primary branches (4.43) and secondary branches (8.66) were recorded in the treatment D2P1 (5.0 x 2.5 m spacing in control). The maximum yield per hectare (8.94 t/ha) was recorded in D1P2 (2.5 x 2.5 m spacing with 2 ml paclobutrazol). Plants spaced at 5.0 x5.0 m and 7.5 x 5.0 m spacing with 2ml paclobutrazol showed beneficial results whereas, to get maximum yield per unit area 2.5 x 2.5 m with 2ml paclobutrazol was effective.
