Abstract
Understanding the complexity, dynamics and
interconnecting soil properties, different tillage practices are critical to
the management of arable soils for crop production. The trial was conducted
during the early and late cropping season (July – October) 2020/2021 and
2022/2023 at the FEYRep (Family Empowerment and Youth Re-orientation Programme)
farm in Etinan Local Government Area (LGA), Akwa Ibom State. The research field
is located between latitudes 4°44'23'' and 4°45'10'' North and longitude
7°50'35'' and 7°59'55'' South of Southern Ima, Etinan. The experiment was (2 x 8) factorial in split
plot arranged in a randomized complete block design with three replications in
both cropping seasons. Treatments consisted of two tillage practices, as main
plots (conventional and reduced tillage), and sub-plots (fertilizer types and
combination), (T1: NPK 400kg/ha,; T2: poultry manure (PM) 5t/ha,; T3: microbial
fertilizer (CHC) 240g/ha,; T4: NPK 400kg/ha + PM 5t/ha,; T5: NPK 400kg/ha + PM
2.5t/ha,; T6: NPK 400kg/ha + CHC 240g/ha,; T7: NPK 400kg/ha + CHC 120g/ha,; T8:
control) given a total of 16 treatment combinations. Although there were no
significant differences amongst the treatments on the soil physical and
chemical properties, combined application of NPK 400kg/ ha + CHC 240g with
conventional tillage increases the pH slightly. Reduced tillage
increases OC and OM.
