Twelve silage hybrids were included in field experiments in Martonvásár in 2007 and 2008 to compare the agronomic traits and chemical quality traits of leafy and non-leafy hybrids. The climatic data for the two experimental years differed considerably. The results reflected the differences in weather conditions. Thanks to the plentiful rainfall in 2008 the hybrids reached their genetically determined height (274.32 cm on average), while in 2007 the average height was only 238.03 cm. In both years a leafy hybrid was the tallest, while the shortest plants were non-leafy. The assimilation leaf area above the main ear was greatest for the five leafy hybrids in both years, with values of 0.35–0.45 m 2 per plant for conventional hybrids and 0.53–0.84 m 2 per plant for leafy hybrids, averaged over the two years. The larger leaf area in leafy hybrids could be attributed both to the larger number of leaves and to the fact that they were broader. The greatest ear mass per plant was produced by Mv Massil (198.66; 320.00 g), a leafy hybrid which also had the greatest leaf area above the main ear. In addition to large green mass (leaf, stalk), an ideal silage maize hybrid should also have satisfactory grain yield. Several of the leafy and non-leafy hybrids in the experiment gave favourable results. In the present experiment the highest starch content was recorded for a leafy hybrid, while the highest protein and oil contents were characteristic of early maturing, non-leafy hybrids. Nevertheless, three of the leafy hybrids had above-average protein content.
