Certified organic farm area in Poland increased 8.5 fold during the 2003-2010 time period to 518 thousand ha, which constituted 2.8% of the arable land. The production costs and profitability of the organic fruit production of apples, strawberries, and sour cherries were evaluated and compared to conventional production of those fruits. The research was based on data from thirty-two commercial fruit farms; twenty farms with conventional production, and twelve with organic production. The main problems associated with organic production were the costs of weed control and soil cultivation. The conventional production of apples turned out to be slightly more profitable than the organic production. The organic production of sour cherries was not profitable. In the case of strawberries, it was the opposite - the organic production gave a better financial outcome than the conventional one

The aim of the study was, based on surveys, to learn about consumer preferences when buying button mushrooms. In Poland, when the consumption of vegetables decreases, the consumption of mushrooms increases, however its level is about two times lower than the EU average. In the first half of 2018, 347 consumers were surveyed in Skierniewice shops and at the local farmer’s market in order to learn about the factors affecting the purchase and consumption of mushrooms. Only twenty people from the population surveyed said they did not eat button mushrooms. Most of the respondents consume them, occasionally or once a month, respectively 46.1 and 41.8% of the answers. Most willingly, the respondents bought mushrooms in 500-gram packs 52.9% indications and in bulk 28.4% of responses. The factors limiting the purchase of button mushrooms indicated the bad appearance of them, 53.2% of responses, and too high price 30.0% responses. Of the population studied, only 139 people buy processed button mushrooms.
