Desuniformidad en maíz: Efecto de la emergencia de dobles plantas en dos espaciamientos de siembra
Year: 2009
Type: article
Abstract: The emergence of double maize plants is a common case of space non-uniformity attributed to faults in the regulation of the\ndrill. The aim of this study was to quantify the response of maize, without water or nutrient limitations, to the emergence of\ntwin plants in two spacing. The experiment was conducted in the Experimental Station of the Faculty of Agricultural\nSciences, Universidad Nacional del Nordeste, Argentina. It was used the hybrid Mill 527 in a batch homogeneous distance\nbetween rows of 0.52 m. and two spaces between plants (E1 0.25 m and E2 0.30 m). Control microplots and double plants\nwere installed, four and five plants respectively for each spacing microplots, with five replicates. Final yield and dry matter\npartitioned into stem, leaf, spike and grain in each of the plants to the microplots was measured. The results show adjusted\nyields range from 10064.3 to 12867.5 kg.ha-1 with a 7% variation among double plants and control in E1 and 2.5% less in\nE2. Density factor caused significant differences (á = 0.05) in adjusted yields but a double plants did not return on the factor\nof the density variation but the difference is not caused significant differences
