This experiment was conducted with the aim to evaluate the effects of six pod drying methods on initial seed germination percentages and seed longevity of groundnut cultivar Tainan 9 stored as unshelled pods. The pods were packed in doubled layered plastic bags after drying. Sun drying on a galvanized iron sheet was the most effective method in reducing seed moisture content with a drying rate at 4.8 % /day, however, the initial germination percentage was the lowest (86 %). Sun drying on other supporting materials such as sail cloth, bamboo mat, nylon net and concrete floor was found to be less effective in terms of reducing moisture but the initial germination percentages were better. The initial germination percentages of the latters were 91, 92, 95 and 97 %, respectively. Regardless of the supporting materials, sun drying reduced the seed moisture content down to 4-6 % within 7 days. Air drying on a bamboo tray took 14 days to dry the seed to 6 % moisture level with the initial germination percentage of 94 %. This experiment is now in progress and the full results will be presented in the next workshop.
