The protein content in maize grain is a key indicator of its nutritional value and averages between 6% and 13%, with a potential range of variation from 4.9% to 23.6%.

The protein content in maize grain is largely determined by the plant's genotype, as the majority of the protein is concentrated in the embryo. Breeding of high-protein lines focuses on selecting hybrids with an increased proportion of this grain part, although a negative correlation between total yield and protein accumulation is often observed due to the plant resource dilution effect.
An important factor in determining protein levels is the availability of nitrogen nutrition during key developmental stages. Nitrogen deficiency leads to a significant reduction in protein content, whereas balanced application of mineral fertilizers allows for the optimization of both quantitative and qualitative crop indicators.
