Abstract: The present study was undertaken to know the effects of high density planting and paclobutrazol on quality and bio chemical parameters 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 acidity content of 0.57% and the maximum carotenoid content of 2.87 mg/g was found in the treatment of D₄P₂ (7.5x 5.0 m spacing and Paclobutrazol at 2 ml). The treatment of D₃P₂ (5.0 x 5.0 m spacing with 2 ml paclobutrazol) recorded the maximum ascorbic acid content of 39.42 mg/ 100 gm, reducing sugars of 5.29% and total sugars 13.75%. The TSS was found maximum (21.25 ⁰B) in the treatment of D₄P₂ (7.5 x 5.0 m spacing with Paclobutrazol at 2 ml) and the Non reducing sugar was found maximum (8.37%) in the treatment of D₃P₁. The treatment D₂P₂ (5.0 x 2.5 m spacing with paclobutrazol at 2 ml) recorded the maximum total chlorophyll of 2.09 mg/g and the Proline content was found in the treatment of D₄P₃ (221.54 µg/g).
