Abstract

Many Iowa soybean producers have adopted Roundup Ready (RR) technology on their farms in recent years. Reduced weed control costs, greater flexibility in herbicide application timing, and the potential for “cleaner” soybean fields are often cited as reasons for using RR technology; however, questions remain about RR varieties’ response to row width and seeding rate. To address producer questions about RR variety response to row width and seeding rate in south central Iowa, a soybean management study was conducted at the McNay Research Farm in 1999 and 2000. Soils at the McNay Research Farm are typical of the Grundy-Haig soil association.
