Abstract
Maize (Zea mays) is a highly important crop globally and also in North Macedonia due to its economic significance, nutritional value, and agronomic importance. To select the most suitable hybrids for the climatic and soil conditions of the Pollog region, a field experiment was established during the 2024 vegetative season using a randomized block design with five replications.
The experiment investigated several production parameters for various maize hybrids, including the number of ears per plant, the number of kernels per ear, the number of kernels per plant, ear weight, kernel weight per ear, cob weight, yield, and productivity.
The hybrids involved in the experiment were from different producing companies and belonged to different FAO groups: FAO-360 (GW3808), FAO 450 (P9911 AQ), and FAO 470 (Pajdash). The results obtained for the different hybrids showed significant differences in the analyzed parameters.
The results indicate that irrigation has a statistically significant impact on yield (F = 60.937, p = 0.000), as p < 0.05. The hybrids also had a statistically significant effect (F = 37.449, p = 0.000). Since p < 0.05, this indicates important differences between the hybrids. Additionally, the irrigation-hybrid interaction was statistically significant (F = 11.906, p = 0.000), with Partial Eta Squared = 0.498, indicating a moderate effect.
