Energy grass research in the beskydy region in connection with non-food land use

Popis výsledku v původním jazyce

The research of grass for energy utilisation purposes is aimed to find a suitable substitute for derelict land of the so-called spontaneous fallow land in the Beskydy region using grass for industrial (energy producing) purposes. It has been found that the most suitable grass types for this purpose under the conditions of the Czech Republic are Rožnovský black bent, the Kora tall fescue, and Rožnovský oat grass. An average yield of dry matter, or green mass respectively, in the above-specified grass types for three harvest years fluctuates from 7.54 - 9.72 t.ha-1, or from 15.96 - 19.61 t.ha-1 (with a minimum amount of fertiliser doses). The highest yield of dry matter in a fertilised option with common black bent amounting to 9.72 t.ha-1 corresponds (based on converted calorific value) to the equivalent of 6.09 t.ha-1 of hard coal. The grass calorific value fluctuated in the range from 16 987 - 19 066 kJ.kg-1 in 100% dry matter. At fallow land, dry matter yields fluctuate varied in low values, namely from 0.78 to 1.35 t.ha-1, which corresponds to the equivalent of 0.65 t.ha-1hard coal. Spontaneous fallow is a negative phenomenon in agriculture, landscape, and even economic terms. As another grass type suitable for energy utilisation purposes under the conditions of the Czech Republic, the reed Canary grass was found, namely the Chrastava variety cultivated in OSEVA PRO Ltd., Grassland Research Station, Rožnov - Zubrí. In addition, it is pointed out in the article that the most suitable time for grass harvesting for energy utilisation is the period harvesting for seed, where thrash-out straw is used for energy producing purposes.
