The article elaborates on the process of farmers organizing themselves into groups in the period of 2004-2016, the regional diversity of the integration of agricultural producer groups, as well as of fruit and vegetable producer groups/organizations. The analysis has been conducted of the financial support provided in 2004-2015; furthermore, the possibility of receiving financial support until 2020 within the scope of producer integration has been explained in detail. After Poland’s accession to the European Union, the opportunity to receive financial support as a part of the Common Agricultural Policy has been one of key factors of the processes of integration in agriculture. The development and success of producer groups/organizations will highly depend on the scope of financial support from national and European funds, as well as on the proper national policy to support big business entities able to compete on global markets. It will also be important to highlight the success of groups already existing on the market, to undertake actions aimed at building trust for other entities, as well as to shape and promote appropriate attitudes of the leaders.
