The seedling growth of maize, their germination rate and seedling length were ascertained using biochar pyrolyzed at temperatures between 400-550oC. All the biochar used were alkaline and contained mineral-rich components such as; C, Ca, O, K, Na, Mg, Si, Al, that could enrich the soil and as well treat acidic soil. Also all the biochar produced are good for planting. However, biochar pyrolyzed at 400oC gave the maximum seedling growth length. The germination rate was between 75%-100%. Biochar produced at 400o C was significantly (P <1.000) greater than SDB450. There is no significant difference between SDB450 and SDB500 (P < .461), also no significant difference between SDB 550 and control (P < .192 at a 95% level of significance. Biochar utilization could be a promising way of reducing the negative environmental effect of fertilizer.
