BORDER ROW DENSITY AND PLOT SEGMENTATION IN CORN EXPERIMENT
Abstract
The objective of this experimento wás to evaluate the effect of border row densities on grain yield and homogeneity of variances in com experiment as well as segmentation of the plots as a mean to increase experiment precision. It was conducted in Santa Maria, RS, during the 1995/96 growing season using four border row densities and two plant populations and the plot was divided in three segmento. There was effect of border row densities on grain yield of the plots and this effect was equal for both populations used. No consistent effect of border row densities on the homogeneity of variances was observed. Segmentation of the plots resulted in an increase in the precision of the experiment. Differences between yields based on yield componente and yields obtained directly wem found.
