Sixteen varieties, fourteen elites from CIMMYT (maize and wheat improvement center) and two local floury flints were tested at two different locations on two types of soil. 1. Tijgerkreek West, with a fine sandy ioam soil of medium fertility on coastal area; derived from Demerara formation. 2. Coebiti, with a coarse sandy loam soil of poor fertility and low pH; derived from Zanderij formation. Compared to local cultivars, CIMMYT elites produced outstanding grain yields of an approximately 7,000 kg per hectare at Tijgerkreek West whereas the local checks produced a maximum grain yield of 5,000 kg per hectare. On the Zanderij formation, at Coebiti the grain yields were depressed by almost f i f ty percent of those at Tijgerkreek West. A significant correlation was found between number of leaves (per plant) and plant height. Plant height and grain yield were negatively correlated.
