Nowadays Poland is during the period of dynamically increasing number of organic farms and organic processing plants. For this reason there is a need of investigations concerning the development of the organic products market, which is the main factor responsible for the development of organic farming system in all countries. The main goal of presented research was the qualification of consumer's knowledge about organic products and organic agriculture system and to indicate the range of necessary activities facilitating the dynamic development of organic products market in Poland. The questionnaire investigations were led in 2006-2008 in chosen consumers groups such as: the customers of organic shops, pupils from secondary schools, students, employees of corporations engaging Polish Television - TVP and those people who are responsible for promotional campaign of organic agriculture in Poland. Over 600 persons together took part in the investigations. The obtained results show, that consumers' knowledge about organic food and organic agricultural system is low. Insufficient information in media is the main cause of such state as well as too complicated method of labeling of the organic products. Despite this majority of the respondents would buy the organic products willingly, if they were easily accessible, clearly labeled and cheaper. In consumers opinion, the interest for organic food is mainly the result of their concern for own health and of the members of the closest family. Moreover the investigation results unambiguously show that the standardized labeling system of organic product should be worked out as soon as possible. Introduction after the German, Austrian or Swiss example of Eko-national sign would be a good solution.
