A Study on Harvesting Mechanization of Soybean Crop

Abstract

The experiments were carried out during the agricultural season of 2003 to evaluate two different systems of harvesting soybean crop to choose the most efficient and economic system as well as to determine the optimum operating conditions for both systems. The first system was harvesting soybean crop by combine harvester (Yanmar-CA760) which was tested at four different forward and cylinder speeds under four various levels of grain and straw moisture contents. The second was harvested by hand sickle then threshed, winnowed by Turkish threshing machine that was tested at four feed rates and cylinder speeds under the same above mentioned moisture contents. All experiments were performed at the research farm of Rice Mechanization Center, Meet El-Deeba, Kafr El-Sheikh Governorate.Results showed that combine harvester (Yanmar-CA760) is strongly recommended since it gave lower losses, damage, costs and higher performance efficiency compared to manual harvesting and gathering followed by mechanical threshing and winnowing using Turkish thresher. The optimum operating conditions for combine harvester (Yanmar-CA760) are at forward speed of 2.6 km/h, cylinder speed of 10.89 m/s and grain moisture content of 18.50%. However, the optimum operating conditions for manual harvesting and gathering followed by mechanical threshing and winnowing using Turkish thresher was at feed rate of 0.5 kg/s, cylinder speed of 11.99 m/s and grain moisture content of 18.50%.

Agricultural Practices Most Suitable for Soybean Production in Fayoum

“…-1 , which led to a decrease in ton production costs to 48.30 pounds ton -1 , taking into account harvesting the crop at a moisture content of 11.5% to reduce field losses, while adhering to the forward speed to operate the machine used in the harvest. In a study conducted by Gomaa et al (2009) to compare the mechanization of soybean harvesting in Kafr El-Sheikh Governorate using both the combine harvester (total operating width of 243 cm) compared to the manual harvest and the threshing with a traditional threshing machine (the dimensions of the feeding slot 118 x 50 cm) had the lowest cost values for harvest (at grain moisture content of 18.5%) they were 265,901 and 394,129 pounds fed.…”

Research on cutting height in soybean harvesting with a combine harvester

“…At present, depending on the efficiency, harvesting of soybeans with a combine harvester and reaping with reapers and after drying, threshing with threshers at the station are used [22].…”
