Producer organizations are one of the newest forms of association in agriculture in the European Union, and they are slowly developing in the Republic of Croatia. Producer organizations in the agriculture associations are mostly formed out of groups of farmers. They are established with the aim of: production planning, increasing the number and placement of products, reduce production costs, stabilizing producer prices, promoting environmentally friendly practices and techniques, improving product quality. The legal framework for the functioning of producer organizations directs Rules of recognition and aid for the launch of producer organizations which defines the basic concepts related to the PO, but prescribes the procedures of establishment and recognition, as well as the functioning of the PO. The Republic of Croatia has so far established and recognized only six producers' organizations, of which the most notable is PO Drava-Sava, which has 189 members. Recognized Pos in the Republic of Croatia are entitled to financial support, such as the State Budget of the Republic of Croatia for the commencement of PO and the European Agricultural Fund for Rural Development, with the support that declines with time. The Republic of Croatia should, in terms of producer organizations, get a hold on the EU countries, in particular Poland and Hungary.
