Rice post-harvest practices and loss estimates in Bangladesh: Threshing through sundrying.

The rice postharvest practices of Bangladesh were observed and losses occurring during the processes from threshing to sun drying were estimated. The practices studied were threshing by hand beating, ox-treading, use of pedal threshers, hand beating followed by ox-treading, cleaning of threshed paddy using a winnowing basket 'Kula' and sun drying of non-parboiled paddy on packed ground, bamboo mats, in the courtyard and on the roadside. The total loss estimates from threshing through to sun drying varied between 3.1 and 4.0% in the 3 seasons studied with a mean of 3.5%. This was equivalent to 0.7 million t of paddy. Losses in threshing and winnowing operations did not exceed 1.0% except in hand beating with a 1.6% mean loss. A similar loss was recorded for threshing by hand beating followed by ox-treading and pedal threshing. Drying loss was estimated at 2.2%.
