In the Czech Republic, agricultural production is still dominated by corporate farms. Private farms have been established since the change of the political regime, but their role is not that relevant as originally anticipated. Among both groups, some have been economically more successful than others. In general, a varying adoption of pr oduction factors is identified as being of influence. Whether their ability to collaborate with other farms is an additional factor which has been discussed under the concept of social capital since quite some time will be analyzed in this paper. Based on the findings of a survey among a sample of 62 farms by adopting factor and multiple regression analysis it can be deduced that social capital is indeed a significant factor determining the level of agricultural income.
