What are some practical methods to increase sweet potato yields?
What methods can increase sweet potato yields? Please advise. To increase sweet potato yields, you can refer to the following methods: (1) Change vine turning to vine lifting. In the past, many farmers habitually turned sweet potato vines, lifting the stems and vines with a wooden stick and beating them hard to prevent them from rooting. During the growth of sweet potatoes, vines are generally turned 2-3 times, causing heavy damage to the stems and vines and reducing yields by up to 20%. Switching to vine lifting can increase yields by more than 10%. The method is: when the field is watered or after rain, lift the stems and vines by hand and move them to another place, so the original leaf layers are not disturbed and the sweet potato stems and vines will no longer root.
