To improve yield, remove lateral branches until the runner reaches the top of the trellis. Leave 4-6 laterals and cut the tip of the main runner to induce early cropping. Removal of lateral branches in the first 10 nodes has a positive effect on total yield.
Pumpkin is a cross pollinated crops; insects, especially bees being the main pollinators. Introduction of beehives ensures good pollination and avoid the need for hand pollination especially during overcast conditions.
During the initial stages of growth, irrigate the crop at 3-4 days interval, and on alternate days during flowering/fruiting. During rainy season, drainage is essential for plant survival and growth.
