Influence of Manures on Some Soil Fertility Properties, Yield and Agronomic Efficiencies of Soybean (Glycine max) on Degraded Acid Soil

Aluminum toxicity is a major limitation to leguminous crop production in acidic soils but mineral and organic fertilizer applications could ameliorate the condition. Thus, focus of this study was evaluate influence manures on post-harvest soil fertility quality, yield agronomic efficiencies soybean (Glycine max). The had six treatments: poultry manures, rabbit pig sheep cattle single super phosphate control (no additive) laid Completely Randomized Design (CRD), with four replicates. experiment conducted at greenhouse Wesley University, Ondo, Nigeria. treatments were applied rate 40 kg P205ha-1 effects parameters (biomass, grain total dry weight), relative efficiencies, as well status observed. Data analysis using ANOVA 5% level probability showed application manure have enhanced component. Poultry treatment highest mean weight 11.5 g while SSP resulted lowest (4.7g). efficiency available P released from 2 times higher than referenced Ondo. again RAEDSW chemical fertilizer. or be excellent materials alternatives (single phosphate) for improving fertility, its efficiencies.
