When it comes to planting continuous soybeans, wise management is essential to get the most from the crop. Learning the proper management steps can give growers another planting option each season.
“When planting a mono-crop, we want to do things that build up yield potential,” said Pioneer Field Agronomist Matt Montgomery. “We want to get beans in the ground earlier. Each day is an additional pod or node, offsetting potential pod attrition and minimizing yield losses.”
Another important area of focus in second-year soybeans is disease management. The best strategy for disease mitigation is to avoid planting into fields that were diseased the previous year.
Soybean variety selection and seed treatment can help fight pests and diseases, regardless of a field’s history.
“A vigorous, multimode of action seed treatment package is a must,” Montgomery said. “You cannot skimp on seed treatment if you’re talking about beans on beans.”
Preemergent herbicides with multiple modes of action can help combat weeds. Selecting mostly weed-free fields is important, as previously weedy fields can present even greater problems for second-year soybeans.
Soybean after soybean planting also often requires additional fertilizer and nutrients. Soybeans need adequate potassium so a potassium fertilizer may be valuable.
