Oil yield
The oil yield is a measure of the agricultural production of vegetable oil on a cultivated area within a certain period of time, based on a certain plant species. It depends on the area yield and the oil content of the plant. These in turn are determined, among other things, by the vegetation conditions (e.g. soil and climatic conditions), the method of cultivation and the type and quality of the seeds.
The oil yield differs greatly depending on the type of plant and the growing conditions. The annual oil yield from rapeseed is around 1,600 l / ha, the oil yield from soybeans around 640 l / ha. The oil yield of hemp is 180 to 350 l / ha per year.
The oil yield is an important target variable in the agricultural cultivation of oil crops, as it has a significant influence on the economic yield. In addition to its economic relevance, the oil yield is also used to assess the area efficiency of crop production, which is becoming more important, especially with increasing competition for land . When using vegetable oil as a renewable raw material for bioenergy (for example as vegetable oil fuel or biodiesel ), in addition to the oil yield, there is also the energy yield, which enables a comparison with other energy crops .
