Abstract

ALVES, SUELI MARTINS DE FREITAS; SERAPHIN, JOSÉ CARLOS; SILVA, ÁLVARO ELEUTÉRIO DA  and  ZIMMERMANN, FRANCISCO JOSÉ P.. Side border arrangement in experimental plots of green corn. Pesq. agropec. bras. [online]. 2000, vol.35, n.11, pp.2145-2150. ISSN 0100-204X.  http://dx.doi.org/10.1590/S0100-204X2000001100004.

In order to study the use of side borders in green corn genotypes evaluation experiments, four arrangements were tested to pre-specify the number of rows in the basic experimental plot. In the arrange 1 the side border study was organized in a way that the results should converge to the center of the plot; in the arrange 2, information was obtained about each side border of the plot; for arrange 3, the information obtained quantifies this effect for each row of the plot; and arrange 4 has provided information about the effect of side related to the central portion of the plot. For this study, data from a 20 corn genotypes evaluation trial for in natura consumption were utilized. Data were separately annotated for each row of the plot, thus permitting utilization of the split-plot scheme. In similar condition arrange 1 or 2 may be recommended for lateral border study, and for corn in natura consumption a two-row side border is required for each side of the plot.
