Field studies were conducted in 1989 and 1991 to investigate the competitiveness of wild mustard with navy beans (Phaseolus vulgaris L.). Wild mustard growing in the crop row was highly competitive with beans sown in rows spaced 53 cm apart. Navy bean yields decreased with increasing wild mustard density. The greatest incremental yield losses occurred at weed densities of less than 20 plants m−2. Estimated yield losses at 20 wild mustard plants m, were 57 and 46% in 1989 and 1991, respectively. Wild mustard competition reduced seed test weight (g 0.5 L−1) less than 4% over the range of weed densities investigated. Key words: Navy bean ’Seafarer’, rectangular hyperbola, seed test weight, weed density, yield loss
