Abstract
This study was conducted to determine the effect of row spacing and variety on the growth and yield of white corn production. three different row spacing: M1 (50cm x 20 cm), M2 (60cm x 20 cm) and M3 (75cm x 20 cm) and three different varieties: V1 (IES Glut 4), V2 (Lakitan) and V3 (Catchupoy) were evaluated, following Split Plot Design in Randomized Complete Block Design (RCBD) with three replications.
Results revealed that IES glut 4 showed significant effect on percent plant stand. Row spacing showed significant effect on number of days after emergence, number of days to tasseling and number of days to maturity.
Among the varieties planted IES glut 4 had significantly highest percent plant stand due to least damage for corn stem borer infestation. Row spacing of 75 cm emerged and matured earliest, while row spacing of 60 cm their tassel emerged earliest.
