28 Jan Farmers Research Planting Wide Corn Rows for Cover Crop Interseeding
Practical Farmers of Iowa has published the results of farmer-led research into planting corn in 60-inch row widths to facilitate the growth of interseeded cover crops. Cooperators evaluated the effect of planting corn in 30- and 60-inch row-widths on corn yield and biomass production by cover crops interseeded to corn in early June. Corn planted in 60-inch row-widths resulted in equivalent yields at two farms and reduced yields at the two other farms. Meanwhile, cover crops interseeded to corn planted in 60-inch row-widths produced more biomass at two of three farms. The research results are available online in PDF.
