Abstract: In Indonesia, maize is the second most important crop after rice and most of the maize production came from small scale farmer. Integrated Maize Crop Management (IMCM) is one of the approaches that recommended by the government to improve maize production. This research’s aim addressed to examine relationship between human capital specific and entreprepreneurial behaviour and their effect on IMCM adoption at the small scale farmers in Bantaeng District, one of the centre maize production development areas in South Sulawesi Province, Indonesia. Respondent sample as much 83 small scale farmers were selected ramdomly. Collected data was analyzed using path analysis for testing hypothesis. This research result showed that human capital specific has significantly and positive effect on IMCM adoption at the small scale farmers, either directly or indirectly. The amout contribution of indirectly effect (through entrepreneurial behavior) is greater than its direct effect. This study provides new evidence on the relationship between human capital specific and entrepeneurial behaviour that play a critical role in influencing the small scale farmer’s decision to adopt new crop technology completely (i.e., IMCM). For practically, this research provide a source of important information for the effort to improve maize crop production management and technology at the small scale farmers.
