Sufficient nutrient levels in leaves of crops have substantial effects on plant growth, development, and grain yield, as it is a fundamental constituent of many leaf cell components. The effect of phosphorus (P), mucuna management options, and nitrogen (N) on the biomass, leaf area index (LAI) and leaf nutrient content of maize on a depleted sandy loam soil in Zimbabwe were investigated. The experimental design was a split-split-plot with two P rates, four mucuna management options, and four N treatments (applied to a subsequent maize crop). Biomass, LAI, and foliar N, P, potassium (K), calcium (Ca), and magnesium (Mg) in the subsequent maize crop were determined. A significant three-way interaction (P < 0.05) between mucuna management options, N rates, and time was observed in terms of biomass production and all nutrients in the leaves of the subsequent maize crop.
