The study was conducted to determine the effects
of different tillage practices on some physical and hydraulic properties of
soils in Hadejia Local Government Area of Jigawa state
during the 2017 cropping season. The field experiment was laid in a Randomized
Complete Block (RCB) Design in factorial arrangements with 4 treatments for
tillage practices-TP (Zero tillage-ZT, Minimum
tillage-MT, Conventional tillage-CT and Deep tillage-DT) and sampling depth-SD (5 cm, 15 cm, 25 cm and 35
cm) all were in four replicates. Data collected were analyzed using the
generalized linear model of Statistical Analyses System (SAS 9.4) for the ANOVA. The results showed that there were significant differences
(p<0.05) in the main effect of TP and SD as well as in the interaction
effect between TP and SD on soil bulk density (Bd), saturated hydraulic
conductivity (Ksat), volumetric moisture content (VWC) at different soil water
potentials and plant available water (PAW). Greater Bd and Ksat were observed
in DT which differed significantly (p<0.05) from other TP while the lowest
was found in ZT with 6.5% reduction than DT. The result further showed no
significant difference in terms of PAW (p>0.05) between the TP at the
average depth of 15 and 25 cm, but they (TP) differed significantly at the
average depth of 5 and 35 cm with the highest in ZT. Higher soil moisture
content retained at all soil water pressure was found in ZT which differed
significantly (p<0.01) form other TP. The research concluded that the best
TP to be adopted in Hadejia in terms of improvement in physical and hydraulic
properties is ZT practice.
