Résumé
The main aim of this research was to evaluate the productivity of the Vertisols in the Gezira Scheme for sugarcane production. To this aim, 4 soil profiles that were physico-chemically characterised and represented important soil units of the Scheme, were selected. Their soil productivity was assessed using two different multiplicative soil productivity index models. In the original model (OPI), available water capacity, bulk density, pH and electrical conductivity were considered. In addition, a modified model (MPI), evaluating the sufficiency of the soil’s available water capacity, pH, clay and organic matter content, was designed in order to improve the applicability of the soil productivity index to Sudanese conditions. In both cases, a weighting factor was included taking into account the root distribution throughout the profile. Both models highlighted a significant variation in soil properties and identified poorly to highly productive soils for sugarcane production. Results showed that PI values calculated with the original (OPI) model were higher than those calculated with modified (MPI) model. The OPI was found to be more suited for application in the Gezira Scheme than the MPI.
