This article is concerned with certain aspects of the entrepreneurial behaviour of wheat farmers - in particular, with their adoption of new techniques and means of production. The study is based on data secured in the course of a field investigation carried out late in 1953, in which forty-eight wheat farmers, residing in a particular locality in northern New South Wales, were interviewed. The primary aim of the investigation was not to estimate the extent to which particular technological innovations are being adopted throughout the wheat belt, or in any particular part of it. Its aim was, rather, to gain some idea of the factors which influence farmers in either adopting or not adopting a particular innovation, or innovations in general. In other words, it sought to explain differences in farmers' entrepreneurial behaviour, rather than estimate the relative preponderance of different types of behaviour.
