Storage of seed potatoes with the Diffused Light Storage (DLS) principle in Nepal
Potato is the second most important staple food in Nepal after rice and it is a source for higher income and a better diet for small-scale rural farmers. Increasing consumption of potato demonstrates its importance for food security; however, seed storage is not easy, especially because temperature fluctuations and excessive light exposure cause its deterioration, jeopardizing availability of quality seed materials. It is crucial to guarantee a good seed storage method for communities that heavily depend on potato production. An efficient practice to overcome the storage problems of potato seed material is the Diffused-Light Storage (DLS) principle, which can be adapted to any existing on-farm storage. If a farmer is able to store his own seed potatoes in good conditions, he enhances the probabilities of a good harvest the following season. This method is based on the use of indirect natural light and good ventilation or air flow instead of low temperature to control excessive sprout growth and associated storage loss.
