BALBINOT JUNIOR, Alvadi Antonio  and  FLECK, Nilson Gilberto. Weed management in the corn crop through plant spatial arrangement and characteristics of genotypes. Cienc. Rural [online]. 2005, vol.35, n.1, pp.245-252. ISSN 1678-4596.

Management practices contribute to reaching high grain yield in corn, which reduce negative effects of weed infestations. The competitive relationship between corn crop and weeds are usually modified by crop plant spatial arrangement and genotype morphophysiological characteristics. This literature review aims to discuss the influence of plant spatial arrangement and corn genotype characteristics in the competition relationship with weeds. Generally, equidistant plant arrangements, achieved through row width reduction, promote greater crop competitivity. Additionally, crop genotypes which present rapid initial growth, and suitable plant characteristics, particularly plant height, can tolerate interspecific plant competition better.

Keywords : Zea mays; row spacing; weed cultural management.
