Maize root growth under regular water content, subjected to compaction, irrigation frequencies, and shear stress
Maize (Zea mays L.) is an agricultural crop grown in the incompressible and alterable savanna soils, which are, with no trouble, compacted by machinery, consolidated by drying and wetting, and insufficiently irrigated. The objectives were to study the effects of: (a) water content and compaction ove...
