Abstract

Over a 3-yr period the placement of weeds in relation to cotton (Gossypium hirsutum L.) plants greatly influenced the seed cotton yields. After 3-yr of competition the cotton with no weeds yielded about 2300 kg/ha. With weeds confined to between-the-rows placement, yields were about 850 kg/ha. When weeds were confined to in-the-row placement, the cotton was completely shaded and produced no yield. After 3-yr of intense competition throughout each entire growing season no statistical differences were demonstrated between the competitiveness of large crabgrass [Digitaria sanguinalis (L.) Scop.], spurred anoda [Anoda cristata (L.) Schlecht.], prickly sida (Sida spinosa L.) and velvetleaf (Abutilon theophrasti Medic.) to cotton.
