Revitalization of Overcrowded and Unproductive Mango (Mangifera indica L. cv ‘Dashehari’) Orchard Through Better Light Interception via Canopy Management

To revive the productivity of unproductive and overcrowded high-density plantation of mango cv ‘Dashehari’ planted at 2.5 × 2.5 m (S1) and 2.5 × 5.0 m (S2), an experiment was carried out at the ICAR-Central Institute for Subtropical Horticulture, Lucknow, UP, India, involving pruning heights—severely pruned (P1) = 1.5 m; moderately pruned (P2) = 2.0 m; lightly pruned (P3) = 2.5 m from ground—and mulching (M1 = organic mulching and M2 = control). Findings showed that canopy volume from 2019 to 2021 was significantly higher in S2 (16.19, 17.45 and 26.84 m3 respectively). The interaction effects were found to be significant, with the maximum canopy volumes (30.56 m3) in S2P3M2, flowering (98
