Soil and water conservation, and soil fertility management effects on rain water productivity of maize hybrid in Burkina Faso

This article assesses the combined effects of Soil and Water Conservation (SWC) practices and soil fertility management on rain water productivity of maize hybrid. On-farm experiments were carried out in two districts of Burkina Faso. The treatments were built as association of two SWC technologies combined with three fertilization options. It is found that the efficacy of SWC practices decrease with the increase in the mean annual rainfall. »
