Determinants of labour productivity on small-holder cocoyam farms in Anambra State, Nigeria
This study used the log linear model derived from the Cobb-Douglas functional form for explaining labour productivity of small holder cocoyam farmers in Anambra State. The study data were collected through a multi-stage random sampling technique from 120 farmers using the cost-route approach in 2005. The study found fertilizer, cocoyam setts, capital and farmer experience to be positively and significantly...
