Abstract:
Field Experiment was carried out at Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari from January 2018 to July 2018 in Sonpari variety of mango. The experiment was laid out in Randomized Block Design with factorial concept and repeated thrice with twenty one treatment combination. The experiment consisted of three planting distance (D) viz., 5 m × 5 m (D₁), 3 m × 3 m (D₂) and 3 m × 2 m (D₃) and seven fruit bagging materials (B) viz., control (B₁) newspaper bag (B₂), brown paper bag (B₃), transparent PP bag (B₄), butter paper bag (B₅), muslin cloth bag (B₆) and non woven bag (B₇). The fruits were bagged at egg stage (55-60 days after fruit set). Results showed that chemical parameters such as TSS, reducing sugars, total sugars, non-reducing sugars and titrable acidity were significantly affected by planting distance. TSS, reducing sugar and total sugars were significantly higher and titrable acidity was significantly lower in the planting distance 5m × 5m (D₁). Non-reducing sugar was found higher under 3 m × 3 m distance (D₂). While, ascorbic acid content and β carotene (μg 100 g^-1) were not significantly affected by planting distance. Regarding effect of different bagging material, TSS, reducing sugar, total sugar, non-reducing, titrable acidity and ascorbic acid were significantly improved by newspaper bag followed by muslin cloth bag while β-carotene content of fruit was significantly higher in brown paper bag followed by muslin cloth bag. No significant effect was found for the chemical properties of mango fruits between planting distance and different bagging material.
