ABSTRACT
In this study, the effectiveness of sole and combined fertiliser treatments of organic fertilisers, O.F (Dinos, 24 mg Zn kg-1; Pacesetter, 190 mg Zn kg-1) and different PRs, (Sokoto rock phosphate-SRP, Ogun RP and crystalliser) for sweet corn performance was evaluated in a slightly acid (pH 6.6) Alfisol and another medium acid (5.9) Alfisol in southwestern Nigeria. Sixteen fertilizer treatment combinations (applied to the test crop) were replicated three times in completely randomised design to give a total of 96 experimental units for the two soils. Treated soils were also incubated for 7 and 28 day(s) prior to determination of changes in pH, available P and extractable Zn. Analyses of short-term and residual effects of the fertilizer treatments indicated better crop performance in the slightly acid (1.40-2.63 g biomass pot-1) than in the medium acid soil (0.57-0.88 g biomass pot-1). Maximum yield and optimum P and Zn nutrition were obtained from combined application of PRs and O.F. Without OF, P and/or Zn applications reduced uptake of Zn by the crop. For sustainable production of the crop on the soils, PRs should be applied in combination with OF as P release from them is improved and Zn toxicity ameliorated.
