Influence of different plant densities and pruning seasons on quality and bio chemical parameters of mango (Mangifera indica L.) cv. Alphonso

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) .
