- In southern guinea savanna of Nigeria, where ofere belongs, the soils are inherently low in P because of the dry nature of the climate, low vegetation cover and generally sandy nature of the soil, whose clay mineralogy is dominated by inactive kaolinite materials. This study was undertaken in Ofere, Kogi State, Nigeria to investigate the response of maize crop to addition of varying rates of phosphorus. The trial, a Randomized Complete Block Design (RCBD) involves seven rates of P (0, 20, 40, 60, 80, 100 and 120kg/ha) applied as single super phosphate (SSP) for P calibration. The soils of the area were analyzed for physical and chemical properties prior to imposition of treatment. In the field calibration studies, optimum maize grain yield of 3.93 and 4.86 ton/ha were obtained for 2007 and 2008 cropping season, respectively from the application of 120kg P/ha. Application of 120kg P/ha is therefore recommended for maize production in soils of Ofere, Kogi State of Nigeria.
