How Low Can We Go?

Weed Control Options
Obviously, weeds need water and heat to germinate and get established. But, as Steckel points out, weed seeds, particularly pigweed, also need light to promote germination. The question is, "How do you compensate for the additional light that is available with lower seeding rates?"
"We didn't see as many weed problems in the narrow-row configuration as we did with the wider rows, especially where there is a skip row," Steckel says. "One option to help suppress weeds is to plant a cover crop in the fall – such as a cereal rye – spray it in the spring, then plant into it."
In addition, make sure the planter is tuned up and as close as it can be to planting a "picket fence" stand, which more quickly provides shade, as opposed to a stand with big gaps.
