The technical feasibility and cost effectiveness of Hermetic Storage (HS) Technology using Volcani Cubes or GrainPro Cocoons as an alternative storage in preserving the quality of registered PSB Rc72H (Mestizo 1) hybrid paddy seeds were assessed. It was compared with other locally used storage technologies, namely: Cold Room Storage (CRS) with 13.0-15.0 °C and 4050 % relative humidity (r.h.); Air-conditioned Room Storage (ACRS) with 27.0 °C and = 60 % r.h.; and Conventional Storage (CTRL) with 28.0-38.0 °C; 60-89 % r.h. Storage trials of 3,6 and 9month duration were carried-out. Six piles measuring 2.95m x 1.70m x 1.50m in length, width and height, respectively were built for observation. Each pile contained 200 bags (20 kg/bag) of one-month old Mestizo 1 hybrid paddy seeds with 9.55-10.45 % moisture content (m.c.). Samples gathered at the beginning and end of storage trials were analyzed based on the following parameters: germination rate, moisture content, insect density, and weight loss. Cost effectiveness per bag was estimated based on the cost of investment and fixed and variable costs of operating expenses during storage. Germination rate of seeds kept in HS for six months was comparable with those in CRS and significantly higher than those in ACRS. However, the reverse was observed after nine months. The germination rate of conventionally stored seeds was maintained at 85 % for three months only. Of the various storage technologies observed, HS was the most effective in controlling insect infestation and reducing weight loss. Ranking of technologies from most to least cost effective was CTRL › HS › ACRS › CRS if storage was for 3 months, and HS › CTRL › ACRS › CRS if storage period was extended.
