The field level extension agents (FLEAs) are the lifeline of the agricultural extension system in Nigeria. Their motivation and job performance are therefore important to achieving faster agricultural development in Nigeria. The study identified the factors motivating the FLEAs working with Ogun State Agricultural development programme (OGADEP) and associates the motivation factors with their job performance level. Eighty of the 126 FLEAs working with OGADEP were selected randomly. The study reveals that financial incentives, remuneration and salary and mobility of staff were the factors rated as the most important motivation factors. The rating also revealed a general low status of FLEAs motivation and job performance. Of the 14 factors identified, boss-subordinate interaction was the only significant predictor of job performance. None of the FLEAs personal factors related significantly with job performance. Policy action needs to consider the adequacy of financing of agricultural extension work in Nigeria in order to achieve sustainable agricultural development over time.
