Continuous cropping with the same crop builds up weeds that match the growth patterns of the crop. Includes descriptions of barnyardgrass identification, ecological impact, and management. Leaves are deep green, flat and with no ligule (appendage at base of leaf). Barnyard grass competes with summer-active crops, producing a considerable bulk of vegetation in late spring.
