Department of Agronomy and Horticulture: Faculty Publications

Field studies were conducted at Rosemount, MN, in 1992 and 1993 to quantify the demographic processes regulating the population dynamics of velvetleaf in soybean as part of a corn-soybean rotation. A consistent 6.8 ± .08% of the total velvetleaf seedbank emerged each year. Less than 21% of all velvetleaf seedlings survived each year in mixture with soybean, due in part to Verticilium spp wilt infection. The probability of seedling survival varied across time of emergence Velvetleaf seed production in the absence of crop competition was 125 and 227 seeds plant^-1 in 1992 and 1993, respectively. Velvetleaf plants that emerged …
