Summary:Faced with climatic hazards that lead to the abandonment of some traditional local varieties of maize (Zea mays L.), a study was undertaken in northern Côte d'Ivoire. Its objective was to determine the effectiveness of different manure on the productivity of these local maize varieties under water deficit conditions during the reproductive phase. The experimental device was a split-plot, the first factor of which was fertilizers and the second, variety. A water deficit was observed during the reproductive phase of the maize varieties studied with a higher ETo accumulation than the water available for the plants. The application of chicken droppings and cattle droppings has reduced the development cycle of black seed maize. The depressive effect of water deficit on yield was more pronounced on the control, unlike chicken dropping and cattle dropping manure, which yielded six times more than the control in the black seed variety. As a result, these manures have reduced the depressive effect of water deficit on the yield of this variety. The use of these manures in maize cultivation could be an alternative to the consequences of the water deficit recorded during the reproductive phase in maize.
