Effect of harvester-threshers upon mechanical damage of barley.Peer-reviewed article

Z. ŠAUER

The article deals with the results of studies aimed at finding the relation between the adjustment of threshing drum and the proportion of mechanically damaged corns of barley harvested with combine harvesters. Two different moisture contents, viz. 20 % and 25 % were compared. The proportion of corns showing signs of mould was higher in barley with higher moisture content. There is a marked direct proportionality between the mechanical damage and mould development. Barley containing only 20 % of moisture, but heavily damaged, has been found to posses minimum germination power. Higher peripheral speeds of drum cause more damage than smaller clearances between the drum and concaves. Impacts are apparently more effective in this respect than friction.
