Abstract. Adoption of crop management practices that are directed at achieving a self- sustaining system for soil protection is critical to sustainable crop productions. The influence of four tillage depth (T₁ = Disc plough and disc harrow at 25 cm depth ; T₂ = Disc plough at 20 cm depth ; T₃ = Double tillage pass of disc harrow at 15 cm depth; T₄ =Single pass of disc harrow at 10 cm depth ,three nutrient applications N₁ = No nutrient application (Control) N₂= FYM at 0.5 ton/hectare (applied at tillage operation) + 50 kg/hectare of Superphosphate applied 4 weeks after sowing N₃ = FYM at 1 ton/hectare (applied at tillage operation) + 75 kg/hectare of Superphosphate applied 4 weeks after sowing and four levels of weed management: W₁ = No weeding as control W₂ = 3 litres of Pre-emergence at planting + Post-emergence (Fusillade forte) at 2.5 litres (0.14kg/ha) of post emergence at 3WAP W₃ = 3 litres of pre-emergence + 3 litres (0.17kg/ha) of post emergence at 5WAP; (Assumed) W4= 3 litres of pre-emergence + 4 litres (0.23kg/ha)of post emergence at 7WAP (Assumed) were used. The results shows that tillage systems between 10-15 cm depth of cut favours the availability and retention of soil nutrients within the tap root of shallow crops as in the case of T3 (DDH at 15 cm) that recorded the highest mean values of SOM (1.77), SOC (1.40), total N (0.41 %), available P of 4.82 ppm and exchangeable K of 0.22 C mol/Kg, during the crop harvest N₃ had the highest SOM (1.90), Mg²⁺ (1.99), Ca²⁺ (1.28), Total N (0.41), available P (4.48) and exchangeable K (1.32) during harvesting time. T3 (DDH at 15 cm) has the highest mean values of pod/plant (74.78), 1000 seed weight (134.83g) and highest mean value of grain yield of 2.55 tonn/ha, not significantly different from yield obtained in T₁ = Disc plough and disc harrow at 25 cm depth Weed management practices did not significantly influence soil chemical properties. It is important that farmers adopt management practices that are directed at achieving a self-sustaining system of the soil.
