Means followed by the same letter are not statistically different from each other. Lowercase letters denote comparisons between genotypes within the same water level
soil, and uppercase letters denote comparisons between the water levels in the soil within the same genotype. Means were compared by Scott-Knott test at 5 % probability |
| Table 3: Agronomic production in four maize genotypes with contrasting characteristics for drought tolerance (BRS1010 and 2B710 - sensitive; DKB390 and BRS1055 -
tolerant) grown under different water contents in the soil (field capacity - FC, and water deficit - WD) (n=6). |
