Resumo: | The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in the State of Santa Catarina, Brazil, during 1996/97 and 1997/98 growing seasons, in a split-split plot design. Early (October 1st) and normal (November 15) planting dates were tested in the main plot; two morphologically contrasting cultivars (an early single-cross and a late double-cross hybrids) were evaluated in the split plots and three row widths (100, 75 and 50 cm) were studied in the split-split plots. The reduction of row spacing from 100 to 50 cm increased linearly maize grain yield. The yield edge provided by narrow rows was higher when maize was sown earlier in the season. Differences in hybrid cycle and plant architecture did not alter maize response to the reduction of row spacing. |

O interesse em reduzir o espaçamento entre linhas do milho tem aumentado nas regiões brasileiras com estação estival de crescimento reduzida, devido a vantagens potenciais, tais como a maior eficiência de uso da radiação solar. Este experimento foi realizado para avaliar o efeito da redução de espaçamentos entre linhas no rendimento de grãos, em diferentes épocas de semeadura e cultivares de milho. O experimento foi conduzido em Lages, SC, durante os anos agrícolas de 1996/97 e 1997/98, em delineamento de parcelas sub-subdivididas. Uma época de semeadura antecipada (1o de outubro) e uma normal (15 de novembro) foram testadas na parcela principal; duas cultivares morfologicamente contrastantes (híbrido simples superprecoce e híbrido duplo tardio foram utilizados nas subparcelas e três espaçamentos entrelinhas (100, 75 e 50 cm) foram usados nas sub-subparecelas. A redução do espaçamento de 100 para 50 cm aumentou linearmente o rendimento de grãos. Os aumentos no rendimento obtidos pela utilização de menor espaçamento entre linhas foram maiores na semeadura antecipada. O tipo de arquitetura da planta e o ciclo do híbrido utilizado não interferiram na resposta do milho à redução do espaçamento entre linhas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSangoi, LuísEnder, MárcioGuidolin, Altamir FredericoAlmeida, Milton Luiz deHeberte, Pedro Canísio2001-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6205Pesquisa Agropecuaria Brasileira; v.36, n.6, jun. 2001; 861-869Pesquisa Agropecuária Brasileira; v.36, n.6, jun. 2001; 861-8691678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6205/3270info:eu-repo/semantics/openAccess2010-08-09T13:36:21Zoai:ojs.seer.sct.embrapa.br:article/6205Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-09T13:36:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
