The aim of this thesis is to compare the cultivation of Styrian oil pumpkin in its relative competitivity to other crops in southern Styria. The gross margin is used as comparative figure. The risks of fluctuating yields and volatile market prices are included in the calculations, by generating various scenarios. To determine future yields and prices based on historical data, the Monte Carlo method is used, from which the value-at-risk is calculated. The data basis for this model is provided by data series of the Arbeitskreis Ackerbau based on accounting records of farms in southern Styria. The oil pumpkin is compared with other significant crops in this region including maize, oilseed rape and winter wheat. The calculation model of the Monte Carlo method and the gross margin are performed in Microsoft Excel. The results of the stochastic model for the yield and the price are incorporated as market revenue in the gross margin. Variable costs associated with the cultivation of the culture are included as current costs in the calculation. The defined gross margin of a culture allows the comparability with other crops. Moreover, by simulating crop yields and prices, the effects of yield fluctuations or price fluctuations on the gross margin of a culture can be seen. The results show that oil pumpkin can usually achieve a better gross margin than other cultures, followed by maize. Generally it can be noted that the gross margin of oil pumpkin is more strongly influenced by fluctuating yields, whereas the financial success of the crops maize, oilseed rape and winter wheat is mainly influenced by the market price of the culture.
