| Mulching the surface of soil after machinery traffic can offset some of the adverse effect of compaction of the soil caused by the machine. Thus, this study reported the response of cowpea (vigna-unguiculata) to compaction and mulching with elephant grass (Pennisectum purpuereum) on loamy sand soil in Southern Nigeria. A randomized split-block design of field plots with compaction levels as the main block and the mulching levels as the sub-block was used. The compaction treatment consisted of 0, 5, 10 and 15 passes of a tractor with a 31 kPa contact pressure while the mulching treatment consisted of 0%, 30%, 60% and 90% areal ground cover. The zero percent treatment served as control and each treatment was replicated twice. The soil dry bulk density,... |
