ZMIANY KOSZTÓW JEDNOSTKOWYCH PRODUKCJI EKOLOGICZNEJ TRUSKAWEK W LATACH 2009-2013

The research was carried out during the time period 2009-2013 on six organic farms with strawberry production and five farms with conventional strawberry production. The weighted average unit cost for organic farms for the whole period 2009-2013, was 3.09 PLN/kg while in the conventional strawberry farms it was 2.33 PLN/kg. The level of yields turned out to be a contributing factor to the level of units cots (the higher the yields the lower the unit costs) what is reflected by a highly significant negative correlation between organic production unit costs and the level of yields on the hectare basis. Improvements of the machines due to lowering of units costs are an absolute must in organic strawberry production both with a view to enhancing competitiveness and to promoting organic growing
