| Popis: | Soil structural indices have a significant effect on the nutrients retention and crop yield. Studies on soil structure indices in the semi-arid zone are minimal despite their importance in controlling water and water transmission, root elongation and erosion. A study was conducted in the area of Hadejia to evaluate the influence of tillage systems (TS) and sampling depths on some selected soil structure indices. The TS were four (4); conventional tillage (CT), reduced tillage (RT), zero tillage (ZT) and chisel plough (CP), while the sampling depths were two – 0-15cm and 15-30cm. Randomised complete block design (RCBD) was used in factorial arrangement. The result showed that the soil is sandy loam in texture irrespective of the TS. Lower dispersion ratio (DR) was observed in ZT with greater aggregate silt + clay (ASC) and water stability index (WSI) which differed significantly (pZT>CT>CP with RT having the highest that differed significantly (p |
