1989
Al-Rawi, M.F.
This study was carried out by using wheat, barley, lentil, chickpeas and corn in different locations of Jordan, to estimate the grain losses during harvesting, transportation and storage. The results indicated that: In Mushagar, (in farm field) the losses for barley and wheat were 7.87 % due to mechanical harvesting, 1 % due to natural causes, while at the research station they were 0.15 % of wheat due to cleaning, 0.36 % due to handling and 0.24 % due to birds. At Ramtha station, for barley, 7.4 % and 6.79 % due to hand and mechanical harvesting, 8.2% due to threshing, 0.8 % due to transportation. At Al-Shajarah site, for lentil 12.46 % and 5.21 % due to mechanical and hand harvesting, respectively and 15.6 % due to threshing. At Al-Sarih lentil grain losses were 49.5 % and 5.5 % due to mechanical and hand harvesting, respectively. In Jureynet-Alflahat, chickpeas losses were 23.75 % due to mechanical harvesting and 4.6 % on ground before harvesting. In Howarah chickpeas grain losses were 5 % on the ground. In Juedeh siloes the grain losses by transportation were 0.23 % of wheat, 1.45 % of barley and 0.65 % of corn, the losses due to storage were 0.66 % for wheat, 2.37 for corn. Several suggestion and recommendations were made to reduce those losses
