Abstract: The present study was undertaken to know the effects of high density planting and pruning seasons 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 (0.53%) was observed in D₂T₁ (2.5× 2.5 m spacing with control), the ascorbic acid content was found maximum (39.39 mg/ 100 gm) in the treatment of D₃T₃ (5.0×5.0 m spacing with pruning during current season growth) and the treatment D₄T₃ (7.5×5.0 m spacing with current season growth pruning) recorded maximum TSS of 21.70 ⁰B. The total sugar content was found maximum (13.34%) in the treatment of D₃T₂ (5.0×5.0 m spacing with previous season growth pruning), highest reducing sugar content (5.19%) was observed in the treatment of D₁T₃ (2.5×2.5 m spacing with pruning during current season growth) and the non reducing sugar content was found highest (8.33%) in the treatment of D₃T₂ (5.0×5.0 m spacing with previous season growth pruning). The treatment of D₄T₂ (7.0×5.0 m spacing with previous season growth pruning) recorded maximum total chlorophyll content (2.15 mg/g) and maximum carotenoid content (2.94 mg/g) and the maximum proline content was found in the treatment D₁T₁ (2.5×2.5 m spacing with no pruning) .
