This study is a contribution to im.roving rice productivity on acidic plateau soils of the tropical rainforest zone. It is based on taking into account the cationic balances of the soil in order to optim.ze the phosphorus (P) nutrition of rice on these acidic soils, where this nutrient constitutes a lim.ting factor for agricultural production. Three (3) pot trials were conducted in Adiopodoum. in the forested south of Côte d’Ivoire. The interactive effects of calcium.carbonate (0, 25, 50 and 75 kg Ca ha−1) and m.gnesium.sulfate (0, 25, 50 and 75 kg m. ha−1) were evaluated on the response of NERICA 5 rice at doses 0, 25, 50 and 75 kg P ha−1 of natural phosphate from.Togo, applied only once at the start of the experim.nt. Additional fertilizers of nitrogen (N) (100 kg N ha−1) and potassium.(K) (50 kg KCl ha−1) were added to each of the tests in a split-plot device. The test results revealed a paddy production potential of approxim.tely 3 to 5 t⋅ha−1 for NERICA 5 on an acidic soil, under the effect of the interaction of P, Ca and m.. The quadratic response of rice yield to the doses of these fertilizers would be m.re dependent on their balance, itself influenced by Ca nutrition. For the sustainability and m.intenance of rice production in agro-ecology studied, it was recom.ended doses of 38 kg Ca ha−1, 34 kg m. ha−1 in a Ca/m. ratio (1/1) with intakes of 41 kg P ha−1, overall in a ratio 1/1/1 (P/Ca/m.) m.re favorable to the availability of free iron considered a guiding elem.nt of m.neral nutrition. Thus, these prom.sing results should be confirm.d in a real environm.nt for better m.nagem.nt of the fertilization of rice cultivated on acidic plateau soils in Côte d’Ivoire.
