The Intensification of cowpea production is a priority because of its role in household income generation and its contribution to food security. To evaluate the effect of organic fertilizers on cowpea productivity, a dispersed block experiment design was set up in Saria in the semi-arid zone of Burkina Faso during the 2017 and 2018 cropping seasons. The combination of Biodeposit (Agro and Elixir) and Organova were used alone or in combination with mineral fertilizer. The results showed that during the two years, the highest cowpea grain yields were obtained with the Organova + the recommended mineral fertilizer and Biodeposit Agro + the recommended mineral fertilizer. The combination of organic fertilizers and recommended mineral fertilizer resulted in a 45% and 59% increase respectively with Organova and Biodeposit (Agro + Elixir). These two fertilizers then have the same effects on cowpea productivity. In the semi-arid zone where there is competition for organic resources, organic fertilizers can be used in combination with mineral fertilizer to improve cowpea productivity.
