The synergistic effect of leaf count for flower induction was investigated in mango cv. 'Himampasand' under Ultra High Density Plantation. The trees are grown in tropical conditions in Tamil Nadu, India, and the trial was conducted by adopting a Factorial Randomized Block Design (FRBD) with three replications and two factors: leaf pruning and month. The experiment was set up in a five-year old orchard with uniform-sized 'Himampasand' trees planted at 3 x 2 m spacing. The treatments were imposed during the middle of October, November and December. Treatments consisted of 0 (no leaves), 1/8, 1/4, 1/2, 1, 2, 3, 4, 5, 6, and control (without leaf removal) leaves remaining on each stem of every treated branch. Under tropical, warm weather, the fractions of leaves / stem are able to induce minimal quantity of flowering without leaves in the shoot. Leaf pruning in different months from October to December had varied effects. However, in a tropical climate, six leaves per shoot and December pruning resulted in 100 per cent flowering in mango cv. 'Himampasand'.
