Successful mechanical weed control is a crucial aspect in organic soybean production. Six weed control techniques (spring tine harrow, inter row hoe with duckfoot sweeps,
separately used or in combinations, inter row hoe with additional tools: finger weeder, torsion weeder, ridging wings) were evaluated concerning the effects on weed ground
cover and on grain yield. Soy bean plant stands have been established with two different row widths using different types of seeders (12.5 cm with seed drill for harrowing variant and 50 cm with single seed drill for hoeing variants). The field trials were conducted at three sites in four years (2011-2014). At harvest, the weed ground cover in the harrowing variant was higher than in the hoeing variants. In the four environments with high weed pressure, the weed ground cover was already higher at pod filling in the harrowing variant. This resulted in higher yields in the hoeing variants in these environments and was caused by a longer period of weed control with hoeing. The additional tools ridging wings or combinations with spring tine harrow increased the success of mechanical weed control and the grain yield in comparison to inter row hoe separately. In the other environments with lower weed pressure, no yield differences were determined between the control techniques.
