Abstract

In two experiments beans were kept weed-free for various periods early in the season, and in a third, weeds were allowed to grow with beans for various periods before being removed. Weeds which emerged soon after planting caused extensive reductions in bean yields, but the actual yield-reducing competition occurred considerably later in the season. For 5 to 7 weeks after planting, the grower must control weeds by chemical or other means; for the remainder of the season, bean competition provides weed control.
