ABSTRACT The purpose of this study was to evaluate whether there is variability in the energy and nutritional composition of maize grains among different genetic backgrounds and sowing dates and to determine whether there are relationships between energy nutritional traits and meteorological variables. In total, 773 grain samples from four maize genetic backgrounds, cultivated across ten sowing dates in the years 2021, 2022, and 2023, were evaluated. Descriptive statistics were calculated, and the principal component, correlation, multiple linear regression, and […]
