Scott Shriver, one of Iowa's leading organic farmers, recently conducted research to determine optimal soybean row-width and seeding dates when roller-crimping cereal rye. The soybeans he planted the day of roller-crimping ultimately yielded higher than those planted 13 and 17 days before. Soybeans drilled in 7.5-in. row-widths also had higher yields and stand counts than soybeans planted in 30-in. row-widths.
