Most of the field operations performed during cultivation of amaranth can be done with the use of conventional agricultural equipment. Many amaranth growers use standard tillage equipment to work the soil : ploughs, disc, chisel cultivators or harrows and roller packers. Also planting can be executed with precision planters or drills; in order to achieve the required seeding rate of about 1–3 kg/ha, diluting of amaranth grain with another ingredient is a common method. Selection of appropriate row-spacing is very important with respect to subsequent mechanical weeding of amaranth plantation. The row-spacing of 40–50 cm allows for application of a standard equipment for inter-row cultivation to control weeds.

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.
