Description
Summary:We determined the influence of N and P fertilizers on growth and tissue N concentration of container grown blackfoot daisy (Melampodium leucanthum Ton. & Gray), a resource-efficient native landscape herbaceous perennial for the southwestern United States. Regression equations derived from the data indicated that maximum growth could be obtained by application of 166 mg N/liter (ppm) in irrigation water if 30 mg P/liter were also applied. However, near maximum growth was obtained with 100 mg N/liter at the 30 mg P/liter level. Fifteen mg P/liter in irrigation water were not adequate for maximum growth. Tissue nitrogen concentrations in whole plants should be > 1.7% for growth not to be limited by N.
