How does the amount of rainfall affect the growth of sweet potato plants?
5 answers
The amount of rainfall significantly impacts the growth of sweet potato plants. Research conducted in South Tapanuli Regency shows a weak positive correlation between rainfall and sweet potato productivity over the last decade. Sweet potatoes require well-distributed rainfall of 850-900 mm annually for optimal growth, as they are warm-season crops that thrive in abundant sunshine and temperatures above 24°C. Excessive water due to waterlogging from heavy rainfall can limit crop growth and yield by causing hypoxia stress, affecting factors like photosynthetic rate and stomatal conductance in different sweet potato varieties. In Indonesia, low sweet potato yields during the rainy season are attributed to the crop's low productivity in wet conditions, leading to deficits in supply despite increasing demand.
