Abstract: The production of rice has its own requirements like other crops, among these requirements include the various soil reactions like acid-base reaction and redox reaction. The experient was set up to determine the effect of different oxido-reduction status of soil on rice performance. The trial was a 3x2x2 factorial experiment laid out in a completely randomized design (CRD) and replicated three times. The variables included 3 levels of organic matter from poultry source (0t/ha, 6t/ha and 8t/ha), two levels of NPK 15-15-15 fertilizers (0kg/ha and 200kg/ha) and two watering regimes (Field capacity and waterlogged) this gave rise to twelve treatments and four redox status (oxidized, moderately reduced, reduced and highly reduced). Redox potential was measured using a redox potential meter, growth parameters of rice collected included plant height measured with tape rule, number of leaves and number of tillers which were counted. Yield parameters collected includes 1000 grain weight and grain yield measured with a electrical weighing balance. Data collected were subjected to analysis of variance using SPSS version 17 and means were separated using Tukey HSD. Results from the result indicated that rice performance was best under highly reduce and moderately reduced soils.
