Abstract: RESUMO A região dos Campos Gerais, no Paraná, é pioneira na utilização de novas tecnologias e apresenta desempenho superior em rendimento de grãos. O sistema Plantio Key words: no-tillage, planting, plant population.A região dos Campos Gerais apresenta rendimentos superiores à média agrícola nacional de produção de grãos, e é pioneira na adoção de novas tecnologias, que visam a incrementar ainda mais os rendimentos obtidos. O sistema Plantio Direto, plenamente incorporado à região, é um exemplo corrente. Tendo… Show more

“…The irregularity in plant spatial distribution along the rows can reduce the use efficiency of water, light and nutrients by plants, increasing the number of dominated plants in the cultivation (Sangoi, 1990;Rizzardi et al, 1994;Schimandeiro et al, 2006). Various factors can affect the uniform arrangement of corn plants, among which the inadequate seed classification with respect to shape, mass and size, the incompatibility between seed size/shape and the discs of sowing machines, inadequate regulation of sowing machine, seed-conducting tubes and the excessive velocity during sowing are the most common causes for the occurrences of non-uniform stands of corn (Trogello et al, 2013).…”

“…0.90 m), a larger number of plants should be planted per row. However, this densification causes failures in the longitudinal seed distribution, reducing the plant population effectively established (Schimandeiro et al 2006). Also, the resulting spatial arrangement for the 0.90 m distance may have promoted greater intraspecific competition in maize.…”

“…Nos três primeiros anos de acompanhamento, os resultados demonstram que 60% das propriedades não se enquadravam neste pré-requisito. Os dados confirmam as afirmações de SCHIMANDEIRO et al (2006) sobre a grande variabilidade na distribuição de plantas na linha de semeadura.…”

“…Ao estudarem a distribuição longitudinal de plantas de milho em 48 propriedades agrícolas, SCHIMANDEIRO et al (2006) concluíram que o processo de semeadura é eficiente quanto ao número de plantas por área; porém, há grande variabilidade na distribuição de plantas na linha de semeadura.…”
