Miscanthus is a plant with high level of energy value, high annual yield of dry matter, low costs of production and high incomes. Due to this reasons, there is increasing interest in Miscanthus cultivated production in last few years. But, Miscanthus is a foreign plant species, and for cultivated production it requires permission from the Ministry of Environment and Nature. In this master`sthesis, we analyzed the costs and the revenues of the Miscanthus cultivated production, also we determined the marginal contribution and cost price of the Mischantus during the economic lifecycle of the plantation (at least 20 years). In the year of full production potential (from fourth till eleventh year after planting) the yield is 19.5 tons per hectare, and cost price is 211 HRK per ton. Marginal contribution in the first two years of planting is negative. In the third year of production marginal contribution is 1,805 HRK, and in years of the full production potential marginal contribution is 5,501 HRK, so production is profitable. The average value of all production years shows that production is economically (E = 1.42) regardless the high initial investment. Also, investment is profitable since in years of full production achieves about about 29% of profit per unit of capital invested. Production of Miscanthus on a family farm present a good alternative to traditional arable crops production, because it requires a significant investment only in the first year of growing, most agricultural mechanization is already available, and it is more profitable and achieves higher profit on the same production area, except in the case of sugar beet.
