How to Achieve High Yield in Pumpkin Cultivation? Latest Methods Explained

Pumpkin is a common vegetable that can be used in cooking, is hard to use for porridge, or can be processed into other agricultural by-products, with relatively high cultivation benefits. So do you know how to achieve high yield in pumpkin cultivation? Follow the editor to learn about it.

1. Trellising and Pinching

When the pumpkin vines grow to about 3 m, it is time to start guiding the vines onto the trellis. Pumpkins are relatively heavy, and the vines alone cannot support them, so a trellis must be set up to bear the weight of the pumpkins. This can also reduce pests and diseases, increase the fruit-setting rate, and prevent the pumpkins from rotting during growth. When the vines grow to about 2 m, pinching is needed at this point, so that the main vine grows branch vines, promoting the vines to flower and set fruit and increasing yield.

2. Preventing Excessive Vegetative Growth

Excessive vegetative growth of pumpkin vines will reduce the number of fruits set, so it is necessary to prevent excessive vine growth. Here, nitrogen fertilizer application needs to be controlled appropriately, and phosphorus and potassium fertilizers should be increased. You can also make a small cut in the middle of the vine with a knife 30 cm from the root of the vine, then insert a small piece of charcoal into the small cut. This can block the transport of nutrients and water, and the top branches and leaves cannot grow without nutrients, which can control excessive vine growth.

3. Spraying on Top and Drenching at the Bottom

Pumpkins are relatively large, so topdressing work must be done well during the fruiting period to improve yield and quality. During the fruiting period, spray foliar fertilizer once every 10 days, using the leaf stomata to dilute the fertilizer. When spraying, spray on the back of the leaves, not on the pumpkins, as this will make the pumpkins rot and thus affect yield. When spraying foliar fertilizer, you can also drench the roots with organic water-soluble fertilizer. This is more effective than the previous traditional fertilization method. This water-soluble fertilizer does not damage the roots, takes effect quickly, and is more easily absorbed by crops.

4. Supplementary Pollination

Supplementary pollination can significantly increase the fruit-setting rate. When female flowers open and can be pollinated, cover them with pumpkin leaves. Between 8 and 9 the next morning, pick male flowers from a different plant and cover them over the female flowers, then remove them after 2 days. In addition, when yellow leaves appear on vines that are flowering and setting fruit, remove them promptly when seen to reduce nutrient consumption and let the pumpkins set more fruit.
