Understanding the roles of women and men in agriculture, and planning programs relevant to their roles and needs is a prerequisite for the success of agricultural development programs. This study analyzes patterns of involvement of farm wives and husbands in agricultural tasks associated with the production of rubber, cocoa, and oil palm. Wives performed repetitive, tedious and time-consuming tasks such as rubber tapping, collecting and processing of latex, rubber sheet drying, harvesting of cocoa pods, and collecting of loose oil palm fruits. Their husbands performed tasks that required technical and operational skills, muscle strength, and the handling of money. These tasks included applying fertilizers, weedicides, and insecticides, pruning oil palm fronds, and harvesting oil palm bunches. Implications of the findings for extension programs include establishing objectives, and organizing training programs and staffing that take into account the needs of both men and women.
