Changes in the proportion and yield of alfalfa and Korean lespedeza in mixtures with grasses
Mays, D.W. Jr.
Abstract: An experiment was conducted on Ruston sandy loam soil at Pine Bluff, Ark., in 1935-37 to determine the yield and change in population of Korean lespedeza when grown alone and in association with Johnson grass, Dallis grass, and Bermuda grass. A similar experiment was conducted on Trinity clay soil in 1935-38 to determine the yield and change in population of alfalfa when grown alone and in association with Johnson grass. Both soils received superphosphate placed at a depth of 6 inches below the soil surface. The investigation indicates that Korean lespedeza is replaced by Johnson grass in a Korean-lespedeza-Johnson grass mixture and by Bermuda grass in a Korean-lespedeza and Dallis grass reach an edaphic climax lespedeza and 50% Dallis grass. Alfalfa is replaced by Johnson grass when grown in an alfalfa-Johnson grass mixture.Show more [+] Less [-]
