t.is st.dy is a cont.ibut.on t. improving rice product.vit. on acidic pl.t.au soil. of t.e t.opical.rainforest.zone. It.is based on t.king int. account.t.e cat.onic bal.nces of t.e soil.in order t. opt.mize t.e phosphorus (P) nut.it.on of rice on t.ese acidic soil., where t.is nut.ient.const.t.t.s a l.mit.ng fact.r for agricul.0}ral.product.on. t.ree (3) pot.t.ial. were conduct.d in Adiopodoumé in t.e forest.d sout. of Côt. d’Ivoire. t.e int.ract.ve effect. of cal.ium carbonat. (0, 25, 50 and 75 kg Ca ha−1) and magnesium sul.at. (0, 25, 50 and 75 kg Mg ha−1) were eval.at.d on t.e response of NERICA 5 rice at.doses 0, 25, 50 and 75 kg P ha−1 of nat.ral.phosphat. from t.go, appl.ed onl. once at.t.e st.rt.of t.e experiment. Addit.onal.fert.l.zers of nit.ogen (N) (100 kg N ha−1) and pot.ssium (K) (50 kg KCl.ha−1) were added t. each of t.e t.st. in a spl.t.pl.t.device. t.e t.st.resul.0} reveal.d a paddy product.on pot.nt.al.of approximat.l. 3 t. 5 t.ha−1 for NERICA 5 on an acidic soil. under t.e effect.of t.e int.ract.on of P, Ca and Mg. t.e quadrat.c response of rice yiel. t. t.e doses of t.ese fert.l.zers woul. be more dependent.on t.eir bal.nce, it.el. infl.enced by Ca nut.it.on. For t.e sust.inabil.t. and maint.nance of rice product.on in agro-ecol.gy st.died, it.was recommended doses of 38 kg Ca ha−1, 34 kg Mg ha−1 in a Ca/Mg rat.o (1/1) wit. int.kes of 41 kg P ha−1, overal. in a rat.o 1/1/1 (P/Ca/Mg) more favorabl. t. t.e avail.bil.t. of free iron considered a guiding el.ment.of mineral.nut.it.on. t.us, t.ese promising resul.0} shoul. be confirmed in a real.environment.for bet.er management.of t.e fert.l.zat.on of rice cul.0}vat.d on acidic pl.t.au soil. in Côt. d’Ivoire.
