The objective of this study was to assess the impact of stump splits density and fertilization on the chemical properties of soil and the chemical composition of biomass in Panicummaximum Jacq. C1. The study was conducted in a split-plot design with three replications at the INERA research station in Burkina Faso. The primary treatments consisted of three densities of Panicummaximum stumps (3 splits, 4 splits, 5 splits), while the secondary treatments comprised five types of fertilization. The results indicated that the five stump splits led to increases in organic matter (12.82%), total nitrogen (13.88%), and CEC (8.3%). The fertilizer (Poultry Manure + Urea at 46% nitrogen) improved soil acidity and increased total phosphorus content by 75.4% and SEB by 17%. In the second year at the first harvest, the three stump splits increased total nitrogen by 18.84% of biomass compared with the four stump splits. In the second year and at the first harvest, the fertilizers NPK+Urea and Cattle Manure + NPK+Urea provided the highest nitrogen rates, respectively 0.48 and 0.32 nitrogen units greater than the absolute control. These findings suggest potential avenues for the production of Panicummaximum as part of an integrated approach to the valorization of local fertilizers.
