APPLICATION OF STANDARD AGRICULTURAL MACHINERY TO HARVESTING AND POST-HARVEST HANDLING OF AMARANTH
Many growers have successfully used various types of grain combines for harvesting amaranth. However, grain loss during this operation is a potential problem. To reduce losses it is essential to make the proper adjustments of concave clearance and cylinder speed. Careful selection of these threshing parameters is especially important, since the moisture content of the grain at harvest can sometimes be as high as 30%. From the other hand, it has been reported that an excessive cylinder speed can cause damage to the grain, lowering the germination rate of seed.
At the Department of Farm Machinery WAU investigations were carried out aiming at determination of possibilities of a standard grain combine harvester application to amaranth harvesting.
