Drilled soybeans in Missouri (1993)
Metadata[+] Show full item record
Drilled (solid) seeding of soybeans is a continually growing practice in Missouri. More than 1 million acres were drilled in 1986, compared to just 300,000 acres in 1979. Solid seeding was predominant when soybeans first became popular in Missouri and the crop was used primarily for hay. At that time, some weed growth in the hay crop was tolerable. As emphasis shifted to production for beans, producers shifted to row culture to permit cultivation for weed control. Improvements in soybean chemical weed control materials now allow adequate control of most weeds in solid-seeded stands. Because they can control weeds, farmers are returning to solid seeding to increase yields. Several long-term research projects (some sponsored by your soybean checkoff dollars) have allowed us to evaluate the yield potential and economics of solid-seeded soybeans throughout Missouri. The following discussion reports some of the important findings of those studies and recommended production practices.
