    Description

    Cultivation, atrazine, and simazine were used for weed control 1, 2, and 3 years following planting of black walnut in Iowa and Indiana. In Iowa, 2 or more years of weed control resulted in the best seedling growth, but in Indiana 3 years proved best. Method of weed control had no significant effect on seedling growth in Iowa, but chemical control resulted in better growth than cultivation in Indiana. After 5 years in the Iowa planting, the walnut seedlings that had received weed control for 2 or 3 years continued growing faster than those that had receieved only 1 year of weed control, even though no weed control was done in at least the last 2 years.
