Improving mechanical in-row weed control for vegetables and row crops
In the crop row, it can be challenging to control weeds mechanically without damaging the crop. Based on the encouraging results of previous research using “stacked” combinations of in-row cultivation implements, we attempted to refine the use of these tools by testing several setups and adjustments. In snap beans, several implement combinations controlled over 90% of the weeds with very little crop damage. In 2-leaf beets, crop damage was unacceptably high, even when using standard implements such the spring tine harrow. But in 4-leaf beets, damage was greatly reduced and satisfactory weed control was obtained with a setup of sweeps followed by finger weeders followed by disk hillers. These setups and adjustments may be used as a starting point for growers investing in this equipment.
