Abstract
The present study was carried out in 1999 rice growing season at the six growing Governorates i.e. Kafr EI-Sheikh, EI-Dakahliya, El-Beheira, EI-Gharbiya and Damietta. The main objective of this study was determination of yield losses during harvest and post-harvest processing methods. The yield losses were determined during harvesting, transporting the crop from the field to the threshing yard, threshing and milling. The results indicated that yield losses ranged between 10.33 % to 28.05 of % according to the harvesting and post harvest processing methods used. Moreover, losses during mechanical harvesting were higher than manual harvesting. Manual harvesting caused the highest losses during transporting the crop from the field to the threshing yard comparing with camel or bull-cart methods. The highest losses during threshing were determined for tractor treading method. In addition, the traditional one-pass milling machine (Engelberg type) resulted in the maximum losses during milling. Losses were maximized when all traditional harvest and post- harvest processing methods ( manual harvesting plus transporting the crop from the field to the threshing yard by labor + tractor treading (Korsa) plus one-pass traditional mill) were used, while the lowest losses occurred when rice was mechanically harvested and threshed and milled by modern one-pass milling machine.
