Spring-Interseeded Winter Rye Seeding Rates Influence Weed Control and Organic Soybean Yield

Table 4

Effect of soybean row spacing and narrow-row (19-cm) seeding rate on soybean and common lambsquarters fresh weights in 2002 and 2003. Data were combined over years and winter rye seeding rates unless denoted otherwise.
