To improve soil fertility, cowpea yield, and promote organic and sustainable agriculture in sub-Saharan Africa, particularly in Chad, a study was conducted on the effect of Rhizobium and compost on cowpea (Vigna unguiculata L.) variety IT99K-573-1-1. This study evaluated the agronomic impact of Rhizobium inoculation and compost application on cowpea production in the Sudanian zone of Chad. Using a randomized complete block design with three treatments (T1, T2, T3), researchers compared growth parameters and yield between treated plots and an unfertilized control. The results indicate that both organic fertilization methods significantly improved plant height, biomass, and grain yield compared to the control. Yield per hectare was improved by 11.39% and 13.92% respectively for the Rhizobium and compost treatments compared to the control.
