Descripción
Seed constitutes a very important part of potato cultivation as it accounts for almost 50 percent of the total cost and it is the main source of diseases. In addition, unavailability of good quality seed potatoes at the right time is another problem in potato cultivation.
Diffused Light Storage (DLS) principle meets the criteria for storing seed potatoes in the hill region at low or no cost, and it can be adapted to any existing on-farm storage. The DLS method is based on the use of natural indirect light and good ventilation or air flow, instead of low temperature, to control excessive sprout growth and associated storage loss. Provided that direct sunlight can be controlled, any kind of existing potato storage facilities can be converted into DLS. It is not necessary to build a new facility and any design used by farmers is good as long as the DLS-principle is adopted.
The objective of this practice is to improve the quality of seed tuber through the DLS method.
