Maize is one of the leading energy, grain-forage, and feed crops in Ukraine and worldwide. The aim of the research was to highlight the impact of maize hybrid seed fraction size on productivity formation and a complex of economically valuable traits. The article presents the results of a two-year field study dedicated to examining the effect of seed size on morphological characteristics, growth, development, and productivity of maize hybrids of different maturity groups: Takt (FAO 200), Marsel (FAO 280), and Tiador (FAO 360). The study considered three seed fractions-small, medium, and large-classified according to the weight of 1000 kernels. The objective was to determine how seed fraction size influences germination energy, laboratory and field germination, plant morphometric parameters, ear height, and ultimately, grain yield. The obtained results indicate that seed size has a stable effect throughout the entire growing season. Plants grown from large seed fractions demonstrated higher growth parameters; in the milk stage, their height exceeded that of plants from small seeds by 6.8 cm and from medium seeds by 5.4 cm. Ear placement was also higher in variants with large seeds: by 3.0 cm compared to the medium fraction and by 6.5 cm compared to the small fraction. The highest values of plant height and ear placement were recorded in the hybrids Takt, Marsel, and Tiador when sown with large seed fractions, which correlated with better biometric and productivity indicators. In the yield structure, a positive effect of large seeds was noted on the weight of 1000 kernels, the number of rows and kernels per row, as well as overall grain yield. On average, over two years, the use of large seed fractions ensured the highest yield level. The yield increase amounted to 0.13 t/ha (1.8%) compared to the medium fraction and 0.44 t/ha (6.01%) compared to the small fraction. Thus, the results of the study confirm the feasibility of using large seeds in maize hybrid cultivation, as this allows for higher production efficiency and better realization of the genetic potential of hybrids under favorable growing conditions.
