Why pandol system is used for growing cucurbits ?

When vine of the cucurbit family vegetable is supported, it grows well. The vines remain good from 6 to 7 months. If on the ground, they remain good only for 3 months. Leaves and fruits do not come into contact with the soil. Because there is adequate ventilation, the risk of rot, pests, and infections is reduced. Proper spraying can be done. The cucurbit family of vegetable crops grow well, and the colour and quality of the fruits are preserved; picking and hand weeding of the crop is also simple.
