Combined Application of Phosphorus Fertilizer with Tithonia Biomass Improves Grain Yield and Agronomic Phosphorus Use Efficiency of Hybrid Maize

Table 4

Grain and total biomass yield of maize as affected by the combined application of Tithonia biomass and phosphorus fertilizer (TSP) (Serbo, years 1 and 2).
