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 (0.38m, 0.52m and 0.38m in a 2x1 skip-row pattern). At the silking-stage of maize crops, soil water content (0-200cm depth) and maximum light capture differed (0.05
