The inadequate yield of maize among smallholder farmers in Ghana has necessitated the implementation of site-specific fertilizer recommendations and the integration of available organic and inorganic fertilizers to achieve increased and sustainable crop production. In an effort to enhance the production capacity of maize in Ghana, a field trial was conducted to assess maize cultivars in the Forest Savannah transition zone at Wenchi and Mampong research stations of the Ministry of Food and Agriculture, Ghana. The Wenchi Municipal is bounded by latitude 7° 301 & 8° 5 N and longitude 2° 15’ W & 1° 55’ E, while Mampong is bounded by latitude 9° 28’ & 7° 4 N and longitude 3° 17’ W & 2° 45’ E. The nutrients evaluated were N (0, 30, 60, 90, and 120 kg N ha-1), P (0, 10, 20, and 30 kg P ha-1), and K (0, 20, 40, and 60 kg K ha-1). The treatment arrangement was an incomplete factorial to limit the number of treatments. Maize varieties, namely Obatanpa quality protein and open-pollinated (QPM, OPV) and Mamaba (QPM Hybrid), were selected for this study. These were laid out in a randomized complete block design with three replications per site-season. The results of the on-farm trials indicated that there were varietal influences on the grain yield, with Obatanpa having a 44% to 82% increase and Mamaba having a 24% to 54% increase over control on Ferric Lixisol. Similarly, on the Chromic Luvisol, Obatanpa and Mamaba recorded grain yield increases of 62% to 75% and 49% to 93% over control, respectively. Mamaba plots with N60P30 +3 t/ha PM recorded a 118% yield increase over control, while Obatanpa had a yield increase of 89% over control. Increasing the level of PM proportionally led to an increased maize yield.
