Effect of Pruning on Physico-Chemical Properties of Mango Cv. Amrapali Under High Density Orcharding

A field experiment was conducted to find out the effect of different level of pruning on physico-chemical properties of mango cv. Amrapali. The size of fruit improved with the severity of pruning treatment. The largest fruit size (11.58 cm) was obtained in light pruned tree followed by severe (10.66 cm) and moderate (10.53 cm) pruning intensities. The maximum fruit weight was recorded in severely pruned branches but it was not significant to other pruning treatment in both years of investigation. The fruit pulp and stone weight were influenced by the pruning intensity and highest pulp weight (169.77 g) and stone weight (43.25 g) were recorded in moderate pruning and were found significant over the other treatment in both the year. The pulp and stone ratio was recorded maximum in severe pruned trees during first and second year in control, respectively. Pruning treatments slightly improved the fruit year (3.92) and in moderately pruned tree during second year (3.93) while minimum in first and second year in control, respectively. Pruning treatments slightly improved the fruit quality of cv. Amrapali with respect to T.S.S., acidity and T.S.S.: acid ratio. Total soluble solids were estimated to be the highest (18.51 B) in moderate pruning and control showed less T.S.S. (17.06°Brix), which was statistically lower than other pruning treatments. Maximum acidity, (0.32 and 0.31% during first year and second year, respectively) was estimated for control but it was not significant to other pruning treatment. The maximum T.S.S.: acid ratio (74.04) was observed for moderate pruning during the first year. In the second year, light pruned trees recorded the highest T.S.S. followed by severe pruning with non significant differences.
