The use of narrow row spacing for the different landscape positions of a field could punish maize (Zea mays L.) grain yield. Two experiments were conducted (2006/07 and 2007/08) at different landscape positions in the Inland Pampas of Argentina. Hybrid DK190MG was grown at the commonest plant density used at each landscape position (approximately 5.1 plants/m2 at the summit, 6.5 plants/m2 at shoulder-slope position, and 7.6 plants/m2 at foot-slope position) with three row spacings (0.38 m, 0.52 m, and 0.38 m in a 2 x 1 skip-row pattern). At the silking stage of maize crops, soil water content (0-200 cm depth) and maximum light capture differed (0.05 less than P less than 0.001) among landscape positions but were similar among row spacings. Differences in grain yield among landscape positions (mean 806, 893, and 1104 g/m2 at the summit, shoulder-slope position, and foot-slope position, resp.) were related to kernel number/m2 (r = 0.94), which was closely related (r = 0.90) to light capture around silking. Grain yield reductions (6 to 20 percent) were recorded when crops were cultivated in rows 0.38 m apart. The skip-row pattern did not improve grain yield. Maize grain yield was optimized in rows 0.52 m apart along the sandy landscape positions of the fields. application/pdf doi:10.1155/2014/195012 issn:1687-8159 http://ri.agro.uba.ar/greenstone3/library/collection/arti/document/2014maddonni eng info:eu-repo/semantics/openAccess openAccess http://ri.agro.uba.ar/greenstone3/library/page/biblioteca#section4 International Journal of Agronomy Vol.2014 http://www.hindawi.com/ ZEA MAYS Row spacing, landscape position, and maize grain yield info:eu-repo/semantics/article info:ar-repo/semantics/artículo publishedVersion info:eu-repo/semantics/publishedVersion
