Women are key players in the agricultural sector of most developing countries of the world. However, despite this major role, men have reportedly continued to dominate farm decision making, even in areas where women are the largest providers of farm labour. This could be counter-productive, because there is bound to be conflict when women, as key players, carry out farm tasks without being part of the decision process, especially when the decisions fail to recognize their other peculiar household responsibilities. Previous efforts at estimating women’s role in agriculture have tended to concentrate on evaluating their labour contributions. There has been little farm-level information regarding their role in decision making, particularly in male dominated cash crop environments like cocoa agro-forestry households. This paper identified socioeconomic factors affecting their contribution to farm decision making. The paper is based on farm level data collected in Ekiti State, southwest Nigeria, from 120 randomly selected farm units. The results of the analysis show that the household socio-economic factors that encouraged high women contributions to farm decision making were their number of years of formal education and farming experience, financial contributions to household farming activities, number of hours spent in the farm, and farm size. Also, the societal constraints militating against women’s contributions to farm decisions were identified and grouped into (a) techno-institutional constraints such as lack of extension programmes and access/awareness of non-governmental organisation (NGO) programmes for women, insufficient knowledge of farm credit sources etc.; (b) socio-personal constraints such as misconceptions that women farmers do not have farming ideas, women are supposed to be subordinate to men in farming, low self confidence by women etc.; (c) economic/financial constraints such as low or lack of financial contributions to farming activities and access to credit support groups such as cooperatives, unwillingness of women to invest in a male-dominated cocoa farming environment. These observations underscore the need for special programmes that empower and recognise women, especially through education, finance and information.
