In a 1-year trial with plants grown at 4 spacings, the rates of total dry matter production and nutrient uptake were determined. Individual plants at the widest spacing (50 x 40 cm) produced significantly more dry matter, owing to their greater nutrient uptake, than closer-spaced plants, but had a similar crude drug (capitulum) yield. The results indicate that the most suitable spacing was 50 x 25 to 30 cm.
