The main aim of the paper is to assess possibilities of implementing behavioural approach and economic experiment in Polish studies in area of agricultural finance. There are two sub-goals: (i) highlighting methodology of economic experiment and indication of technical subtleties concerning agriculture; (ii) identification of potential areas of implementing behavioral approach and experiment in agriculture finance. The article verifies following thesis: economic experiment that was carefully planned and carried out, closely related to the behavioural approach , in addition to traditional research methods, contributes to clarification of more complex financial problems of agriculture. The article also presents the current state of research reffering to behavioral approach and economic experiment, as well as indication of potential areas of exploiting them in agricultural finance. Behavioural approach and economic experiment, complementary to traditional research methods , significantly enrich the research workshop of financiers. There are many limitations of using economic experiment. Both processes of integration of Polish financiers dealing with the agricultural sector and also establishment of cooperation beyond the rigid framework of research areas should be reinforced. Taking into account trends in development of modern economic sciences, behavioral finance with economic/financial psychology will play a more significant role in explaining financial processes of the agricultural sector.
