The study assessed the agronomic effectiveness of fertilizer use recommendations in western Kenya on maize yields. The treatments included: FURP – 75kg N/ha CAN and 26kgP/ha DAP; 2) FURP – 75kg N/ha CAN and 26kgP/ha DAP plus lime (2t/ha); 3) FURP – 75kg N/ha CAN and 26kgP/ha Minjingu phosphate rock; and 4) Rutuba bio Agricultural organic manure at 125kg/ha and DAP at 13 kg P /ha. Inclusion of agricultural lime and manure in combination with mineral fertilizers significantly increased yields in this rather acidic environment.
