In developing countries (such as Nigeria), labour is an essential factor in farming. This is because most of the farming activities are carried out with the use of labour. However, the advent of technological development has had an influence on labour availability. In view of the importance of labour in Nigerian agriculture, this study examined the effects of technological changes on labour availability.

The result of the ANOVA shows that there
