Abstract: A trial was carried out in Sri Lanka on the outdoor storage for 6 months of locally grown paddy (type Nadu) in two hermetically sealed flexible liners termed 'storage cubes'. Insect infestations failed to develop in both cubes and TGM evaluations indicated a 0.33- 0.64% loss in dry weight due to metabolic activity. In one of the cubes, which contained paddy at higher moisture contents, a moisture condensation effect was revealed on the under-side of the upper liner. Losses by mould development resulting from this effect were estimated at 1.24%. Means for obviating this occurrence are proposed.

Key Words: paddy, rice, Oryza sativa, hermetic storage, plastic liners, storage in the tropics, loss-evaluation.
