Abstract:
Background and Objective: Efficient use of water by crops is essential in the savannah areas in the North of Côte d’Ivoire. Therefore, the agricultural exploitation of soils in these areas requires a better knowledge of the hydric constraints of crops. This study aimed to assess the hydrodynamic characteristics of soils and the water constraints faced by crops in the Tiangakaha, Nibolikaha and Napalakaha villages, in the North of Côte d’Ivoire. Materials and Methods: Soil samples were taken and analyzed in the laboratory for texture and organic matter content. Bulk density was determined by the cylinder method. After measuring water infiltration into the soil by the Muntz method, samples were taken to determine the soil water contents and reserves. The ANOVA was done, using the R software, to compare data between the villages and to perform the Newman-Keuls test at the 5 p.c. level. Results: The soils of Tiangakaha and Nibolikaha areas were permeable, while that of Napalakaha was very permeable. The easily usable water reserves (EUR) were higher (14.25 mm) in the 0-20 cm layers in Napalakaha and lower (9.58 mm) in Tiangakaha soils. In the 20-40 cm layers, the EUR of Nibolikaha was greater (16.06 mm) than that of Tiangakaha (10.71 mm). Conclusion: The potential for using soil water reserves by crops was lower in Tiangakaha, where the soil is silty, with the highest bulk density.
