Multifuncionality has become a central concern at both conceptual and empirical levels. In this study, a comparative evaluation of the economic performance of conventional and multifunctional farms (mainly organic farms) was conducted for Lake Kerkini region (North Greece) with the use of mixed integer non-linear programming method. Economic performance was evaluated in terms of farm income, resource allocation, production level etc. The results indicate that multifunctional farms have overall better economic performance and young farm managers are keener to adopt multifunctional farming than the older ones.
