Abstract

The present study was carried out to evaluate three harvesting systems based on machine and workability of the operations performance for wheat production. Wheat is the most unique of all grain crops in its adaptability to harvested in different method. Three methods under study are evaluated, namely: green combine-bagger or tank (first method; reaper + thresher (second method) and the manual (third method). The evaluation of harvesting systems involves a number of modeling approaches and the models fall into: The first is evaluating machine performance by measuring machine capacity and the labour requirement. The second parameter is workability, which is calculated measuring the two mean factors, mainly, the length of harvesting period and potential harvesting hours. The third is economical evolution which is dun calculating fixed costs, operating costs and optimal harvesting capacity. It is important that unproductive work be minimized. Therefore, Optimum harvesting operations as well as good systems is needed to minimize the cost and obtain maximum profits. The required of the labour number for three systems under studies were 5; 2; 15 and 23 labour per harvesting systems for combine with tank, combine with bagger, "reaper + thresher" and "manual + thresher" systems respectively. Also, the total manual energy required "kW.h/ton" recorded 0.8 kW.h/fed while; it was about 6.73 kW.h/fed for the manual system. Regarding to the purchase price of combine machine, the power per unite area is very small but the inertia cost is very height.
