Abstract The objective of this study was to evaluate the effects of the presence of Commelina diffusa weeds on the agronomic characteristics and mineral content of bean grains (Phaseolus vulgaris L.). The experiments were conducted using a completely randomized design with five replications in a greenhouse. The treatments consisted of two bean cultivars (BRS Ametista and BRS Estilo) grown in the presence and absence of the weeds. The weeds affected the agronomic and mineral characteristics of the varieties; caused a decrease in the number of leaves; reduced the chlorophyll content in the leaves; and reduced the nitrogen, phosphorus and iron contents in the grains. Competition with spreading dayflower did not cause significant effects on the stem diameter...
