The production of organic food entails particular difficulties, which can be seen especially in the initial period of the implementation and improvement of the system. The success of the activities undertaken in this area can be measured by analysing the evolution trend of this kind of agricultural production, which is the aim of the present study. The trend was specified in relation to the number of organic agricultural producers and the size of the organic utilised agricultural area in the 2004-2014 period. The study used the method of least squares. In the analysed period, a clear linear trend can be seen in the shaping of the above mentioned parameters, with the trend being upward until 2013. As indicated by the defined trend functions, the number of organic agricultural producers in Poland may exceed 43 thousand in 2020, and the organic utilised agricultural area may reach 1.12 m. ha, assuming that no factors will occur that may seriously disrupt the functioning of the market.
