The effect of variation in soil texture on the phenotype of an early maturing downy mildew resistant (DMR-EST) yellow variety of maize (Zea mays L.) was investigated. The four soil types used were of different textural classes, namely clay loam, sandy loam, sandy clay and sandy-clay loam. Five plastic buckets of 5 L size were filled with each soil type, making a total of 20. The buckets were labelled appropriately and arranged in a Completely Randomized Design (CRD) in the screen house of the Cocoa Research Institute of Nigeria (CRIN), Ibadan, Nigeria. Three seeds of maize were sown in each bucket and later thinned to one plant two weeks after planting. Watering was done at an interval of three days. At the blooming stage, leaf length, leaf width, plant height and stem diameter were measured using a tape graduated in centimeters. After harvest, grain weight and grain weight per ear were determined using a weighing balance. Cob length was also measured using a tape graduated in centimeters and the number of grains per ear was counted. Data amassed were subjected to analysis of variance (ANOVA) and means separated using the Least Significant Difference (LSD). The only character that was stable across the soil types is the grain weight. All other characters varied from one soil type to the other
