AB  - The study presents the effect of cutting height (10, 15 and 30 cm) on yield, nutritional value and chemical
composition of silage corn. The experiment was carried out under dryland conditions and the silage corn was
harvested with three types of self-propelled silage harvesters. Cutting height increased linearly with increasing
operating speed of silage harvesters. For all types of silage harvesters, the cutting height of 30 cm had a
statistically significant (p≤0.05) effect on losses of yields. The numerical value of the R2
factor (from R2
= 0.8978
to 0.9896) shows a strong dependence in all harvesters for all three cutting heights. The regression coefficients
(b) show a significant deviation from the theoretical cutting height at 10 and 15 cm (b = 0.6676 and b = 0.6715),
and very significant (b = 2.0249) at the theoretical cutting height of 30 cm. With an increase in cutting height,
the nutritional value of silage increased. At a cutting height of 30 cm, during the test period in all types of
harvesters, the crude protein (CP) content was significantly (p≤0.05) higher than at a cutting height of 10 cm
(harvester C = 6.94% at 10 cm, harvester B = 8.15% at 30 cm). The cutting height of 30 cm influenced a
significantly (p≤0.05) lower crude fiber (CF) content of harvester Claas Jaguar 850 (21.19%), compared to
John Deere 6810 (24.33%) at a height of 10 cm. The crude ash content (CAsh) did not vary significantly under
the influence of cutting height. Starch content was statistically higher (p≤0.05) in all types of silage harvesters
during the test at a cutting height of 30 cm (28.2% harvester New Holland FX 28, 33.8% harvester
Claas Jaguar 850). The content of calcium (Ca) was significantly higher at a height of 30 cm for harvesters
John Deere 6810 and Claas Jaguar 850 in the third year, while no significant difference was found for
harvester New Holland FX 28. For phosphorus (P), there was no significant difference depending on the
cutting height, but it did exist depending on the year.

AB  - The shape and the size of maize seeds are the most variable traits, which are determined by a genotype and environmental conditions. The aim of this study was to understand the effects of the mechanism of the relationship and significance of seed variability on germination and morphology of seedlings. The seeds of five hybrids ZP388, ZP434, ZP555, ZP606, and ZP6263 were used in this study. The following seed traits were analysed: physical ones: seed length (L), thickness (T) and the width (W); morphological ones: seed weight (SW), seedling length (SLW), root length (RL), shoot length (SL) and seed germination (G) as a phydiological trait.There are statistically significant differences not only among physical traits of the seeds of the five hybrids (p≤0.05), but also among the morphological traits (p≤0.05). Statisticlly significant differences (p≤0.05) in the width (W), length(L) and thickness (T) of seeds of all hybrids were determined in the small flat fraction (SP). The large rounded seed fraction (KO) mainly differed in the width and thickness between hybrids ZP434 and ZP 555, while the large flat seed fraction differed the most in the length between these two hybrids. Large-flat (KP) seed fractions are also characterized by the highest germination (99%). As the seed weight increases, the seedling weight decreases (R2=0.527). Segmentation within hybrids according to the diversity of morphological and physiological properties of seeds was carried out according to the seed size, fraction and seedling weight, while the other parameters were less important. The characteristic of all hybrids is that large seeds of the KP fraction have high germination and well-developed seedlings.
