Abstract: Reduction in row spacing provides a more uniform distribution among plants that can increase grain yield. The benefits of narrow row spacing can depend on the plant architecture and on the kind of crop management system. The objective of this study was to assess the effects of narrow row spacing on the grain yield of maize hybrids growing under different management systems. Six experiments were carried out in Eldorado do Sul, State of Rio Grande do Sul, Brazil, during the 2003/04 and 2004/05 growing seasons. E… Show more

“…P30F53YH is an early cycle hybrid that has decumbent leaves. Hiper and super early hybrids with erect leaves and short plant height are more responsive to crowding than early hybrids with flagged leaves (Strieder et al, 2008). When grown in low densities, P30F53YH has the ability to emit productive tillers which can also contribute to decrease plant density effects on grain yield (Sangoi et al, 2011).…”

“…A interação genótipo x densidade apresentou o maior quadrado médio (QM) quanto à alteração da PG. Esse tipo de resposta também foi observado em outras culturas produtoras de grãos, como soja, milho e trigo (Lima et al, 2008;Strieder et al, 2008;Silveira et al, 2010), o que mostra que a adaptabilidade e a estabilidade da PG para essas espécies estão altamente ligadas à densidade de plantas e ao ano de cultivo.…”

“…The adjustment of optimal sowing density in different cultivation conditions may benefit the change of the grain productivity plateau. The positive answersin use of higher densities were also observed in cultures as soybean, corn and wheat (Lima et al, 2008;Strieder et al, 2008;Silveira et al 2010). In wheat, Zagonel et al (2002) showed that higher density of plants may favor the increase of grainproductivity, to the point of identifying genotypes that were responsive to the increase of the population.…”
