Side border arrangement in experimental plots of green corn

In order to study the use of side borders in green corn genotypes evaluatio n experiments, four arrangements were tested to pre-specify the number of r ows 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 th e plot; in the arrange 2, information was obtained about each side border o f 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 we re utilized. Data were separately annotated for each row of the plot, thus permitting utilization of the split-plot scheme. In similar condition arran ge 1 or 2 may be recommended for lateral border study, and for corn in natu ra consumption a two-row side border is required for each side of the plot.
