Storage and Preservation
Shelf Life
White sweet potatoes have a relatively long shelf life if they are stored properly. They can last up to two weeks at room temperature, but they will last longer if they are stored in a cool, dry, and dark place. If you want to store white sweet potatoes for longer than two weeks, it is best to store them in the refrigerator. They can last up to three months in the refrigerator.
Best Practices
To ensure that your white sweet potatoes last as long as possible, there are a few best practices that you should follow. First, make sure that you choose white sweet potatoes that are firm and free of any bruises or soft spots. Soft spots can indicate that the sweet potato is starting to spoil, and it will not last as long as a healthy sweet potato.
When you bring your white sweet potatoes home, store them in a cool, dry, and dark place. A pantry or cellar is a good option. Do not store them near any fruits or vegetables that produce ethylene gas, such as apples or bananas, as this gas can cause the sweet potatoes to spoil more quickly.
If you want to store your white sweet potatoes in the refrigerator, make sure that you place them in a plastic bag with some holes punched in it. This will help to keep them from drying out. You should also make sure that the temperature in your refrigerator is set to between 55 and 60 degrees Fahrenheit.
By following these best practices, you can ensure that your white sweet potatoes last as long as possible and that they retain their flavor and nutritional value.

Challenges and Concerns
Pest and Disease Management
White sweet potato production faces various challenges related to pest and disease management. The most common pests that attack white sweet potato include sweet potato weevils, cutworms, and wireworms. These pests can cause significant damage to the crop, leading to reduced yields and quality.
To manage these pests, farmers use various methods such as crop rotation, use of resistant varieties, and integrated pest management. However, these methods are not always effective, and farmers may resort to using chemical pesticides. The use of pesticides can have negative impacts on the environment and human health, and therefore, farmers need to use them judiciously.
Diseases such as sweet potato virus disease and Fusarium wilt also pose a significant threat to white sweet potato production. These diseases can cause stunted growth, yellowing of leaves, and reduced yields. Farmers need to adopt disease-resistant varieties and practice good crop management practices to minimize the risk of disease outbreaks.
Climate Change Impact
Climate change is another challenge that white sweet potato production faces. Changes in temperature and rainfall patterns can affect the growth and development of the crop. For instance, high temperatures can cause reduced tuber formation and poor quality roots. On the other hand, excessive rainfall can lead to waterlogging, which can cause root rot and other diseases.
To mitigate the impact of climate change, farmers need to adopt climate-smart agriculture practices such as conservation agriculture, agroforestry, and water harvesting. These practices can help improve soil health, increase water use efficiency, and enhance crop resilience to climate change.
In conclusion, white sweet potato production faces various challenges related to pest and disease management and climate change. However, with proper management practices and the adoption of climate-smart agriculture, farmers can overcome these challenges and improve their yields and income.
