Abstract: The experiment design was a randomised complete block of four treatments replicated three times each, 4× 3 factorial design. The plots were planted with an improved maize seed variety. Collected data include plant heights, number of leaves per plant, leaf length and breadth, the weed dry weight per square metre of each weeding and yield parameters like cob weights, cob lengths, cob circumferences and maize shelled weights. One way-ANOVA and descriptive statistics were used in data analysis. The results revealed that there was a significant effect (p= 0.0194, p= 0.0172), of the mechanically heaped and manually heaped methods on the maize plants- cobs' circumference and cobs' length. Weeds' heights and weights were higher in the manually cleared land, sprayed once plot than all others. There were stronger relationships between the independent variables, different cultivation methods and the yields of maize with the higher R 2 values of 0.76 and 1.00. Soil fertility improves via different cultivation methods as shown in maize yield. There was significant effects of mechanically heaped and manually heaped methods on the number of grains in cobs selected at random and cobs' yield weight in tonnes/acre (p= 0.044, p= 0.012).
