Abstract
Cilj rada je utvrditi visinu biljke, broj izboja po jedinici površine i prinos suhe tvari trave (Miscanthus x giganteus) (u jesenskom i proljetnom roku žetve) gnojene krutim stajskim gnojem (10, 20 i 30 t/ha) i mineralnim gnojivima (50 i 100 kg N/ha) u petoj godini uzgoja. U 5. godini uzgoja (2015.) nije bilo značajne razlike u prosječnim visinama biljaka miskantusa između gnojidbenih tretmana (P>0,05). Prosječna visina svih biljaka između tretmana iznosila je 3,31 m, što premašuje visine biljaka miskantusa u različitim europskim zemljama. Isto tako u petoj godini uzgoja miskantusa nije bilo značajne razlike u broju izboja po m2 između gnojidbenih tretmana (P>0,05). Prosječan broj izboja svih biljaka po m2 iznosio je 54,91. U petoj godini uzgoja prosječni prinos svih biljaka u jesenskom roku žetve je iznosio 36,03 t ST/ha, a razlike među gnojidbenim tretmanima nisu bile statistički značajne (P>0,05). U proljetnom roku žetve ostvaren je prosječni prinos od 23,61 t ST/ha, bez značajnih razlika među gnojidbenim tretmanima (P>0,05). U proljetnom roku žetve došlo je do smanjivanja prinosa ST miskantusa za 34,5% u odnosu na jesenski rok žetve (P<0,05). To je uobičajena pojava kod miskantusa koji prezimljava na polju jer dolazi do opadanja lista i cvatova. Međutim ovim besplatnim sušenjem se dobiva kvalitetnija sirovina za izgaranje, a otpali biljni dijelovi povećavaju organsku tvar tla i njegovu plodnost. Može se zaključiti da gnojidba različitim izvorima i količinama dušika nije značajno utjecala na visinu biljaka, broj izboja i prinos suhe tvari energetske trave Miscanthus x giganteus u 5. godini uzgoja.

The aim of the study was to determine plant height, number of shoots per unit area and dry matter yield of (Miscanthus x giganteus) grass (in autumn and spring date of harvest) fertilized with solid manure (10, 20 and 30 t/ha) and with mineral fertilizers (50 and 100 kg N/ha) in the fifth year of cultivation. In the fifth year of cultivation (2015) there wasn't significant difference in average plant heights of miscanthus grass between fertilization treatments (P>0.05). Average height between treatments was 3.31 m, which exceeds miscanthus plant heights in different European countries. Equally in the fifth year of cultivation there wasn't significant difference between number of shoots per square meter between fertilization treatments (P>0.05). Average number of shoots per square meter was 54.91. In the fifth year of cultivation average yield of miscanthus in autumn date of harvest was 36.03 t ST/ha, and difference between fertilization treatments were not statistically significant (P>0.05). In the spring date of harvest the average yield was 23.61 t ST/ha, without significant differences between fertilization treatments (P>0.05). In the spring date of harvest there was a decrease of yield of dry matter of miscanthus by 34.5% compared to the autumn harvest date (P<0.05). This is a common occurrence with miscanthus who survives over the winter period on the field because there is a decline in leaf and inflorescence. However with this free drying it gets better raw material for combustion, and fell off plant parts increase soil organic matter and it's fertility. It can be concluded that fertilization of different sources and quantities of nitrogen has not significantly affected the plants height, number of shoots and dry matter yield of Miscanthus x giganteus grass in the fifth year of cultivation.
