Abstract

Nut tree culture in Iowa is confined almost entirely too selected and grafted varieties of the black walnut, Juglan nigra L. This tree is one of the dominants of the Elm-Ash-Walnut Associes of the Deciduous Forest Formation of eastern United States. Its native habitat is the upper flood-plains of rivers, creeks and even intermittent streams. In spite of the fact that Iowa is near the western limit of its range, the walnut thrives in the rich alluvial soil of well drained but moist floodplains throughout the state and attains a size almost as great as it does farther east near the center of its range.
