      abstract = {A field experiment was conducted to evaluate the effect of spent mushroom substrate (SMS) on nutrient value, growth and yield of Ipomea batatas (sweet potato). SMS was applied at five levels namely 0ton/ha-1(control) 20ton/ha-1, 40tons/ha-1, 60tons/ha-1 and 80tons/ha-1. Treatments were laid out in a Randomized Complete Block Design (RCBD) in three replicates. The experimental plot was cleared, raised beds prepared and SMS were applied soon after seed beds preparation. Sweet potato vines (3cm) were planted two weeks after treatments. Vine survival rate, vine length, tuber weight and tuber length were determined. Harvested tubers were later subjected to proximate and nutrient analysis in the laboratory. Result obtained from the study shows that application of spent mushroom substrate (SMS) enhanced sweet potato vine survival rate, encourage higher vine length and tuber weight significantly (P>0.05). Similarly, higher percentage crude protein, fat and crude fiber content were recorded across various treatment levels, but variability in carbohydrate content across the various levels of the substrate did not differ significantly (p<0.05). Calcium, Nitrogen and Phosphorous content recorded across the levels of the applied mushroom substrate were higher than values obtained at the control experiment, indicating ability of the substrate to enhance absorption and deposition of the essential nutrient in sweet potato.},
