An experimental farm plot was set up at the National Centre for Agricultural Mechanization (NCAM), kilometer 12 Ilorin-Idofian Road to investigate the effect of various agronomic operations (mound, ridge and plough tillage) on soil moisture content of varying depth intervals of 0 – 15 cm, 15 – 30 cm, 30 – 45 cm and 45 – 60 cm respectively. The experiment was conducted between year 2007 and 2009. Samples were taken on weekly basis from various depths using hand screw auger. The percentage moisture was determined by oven drying oil sample to a constant weight at the temperature of 105°C. The difference between the initial weight and weight after oven drying was calculated and the percentage determined. Weekly data generated were grouped on monthly basis and the means calculated. Seasonal values were also calculated. ANOVA and the Post Hoc multiple comparison were employed to investigate variations in soil moisture content between tillage systems and within the four soil depths. The result showed mound tillage to be the driest and ridge was then wettest of all the tillage system considered. The difference between varying intervals of seach tillage became more pronounced between depth intervals of 0 – 15 cm and 15 – 30 cm. Generally, the result of ANOVA indicates seasonal variation in soil moisture between the three tillage methods at all depths considered. Again the result of the Pos Hoc multiple comparison shows that variation in soil moisture content between the 3 tillage systems in wet and in dry season in not significant because the p value > 0.05. Suggestions were made on the way forward towards achieving a self sufficient food production status.
