Abstract:
Despite the advantages of mechanical harvesting in reducing labor and reducing harvesting time and costs, using a combined harvester during the mechanical harvesting of corn causes an increase in the loss rates, the losses occur due to the effect of the various harvesting devices (table, thresher, winnowing, and sifting). This research aims to determine the loss percentages that occur with the effect of each of the different harvesting devices. The experiment was conducted on two cultivars of fodder corn, which are the most common among farmers in Aleppo province. Golden West variety harvested at speed of 2.44 km/h. Indaco variety, harvested at speed of 3.33 km/h. The results showed that for Golden West variety the losses due to the effect of the table was 12.03%, the thresher device 18.4%, and the winnowing and sifting devices 0.15%, thus the total loss was 30.85%. As for Indaco variety, these values were 6.7%, Corn, Combine, Mechanical Harvesting, Total Losses, Quantitative Loss, and Qualitative Losses.14.5%, 0.56%, respectively, and the total loss was 21.74%. Losses in both cases are high and this can attributed to several factors, the most important reason that is the oldness of the machine and the failure to adjust its calibers correctly during harvesting.
Key Words: Corn, Harvesting Devices, Loss Rates, Quantum Loss, Qualitative Loss.
