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...

The objectives were to study the effects of: (a) water content and compaction over root length, root penetration and root volume under soil water content requirements, and (b) shear stress, and normal tension on root growth. The methods were: Proctor test, water meters, watering frequency, 30x30x1.5 cm plastic cylinders, randomized block designs and factorial simple treatment, four compaction levels per layer (0, 12, 24 and 36), four soil water contents with four irrigation frequencies (daily, inter-day, every two days and every three days) and water amount of 10% to 13% with mean value of 11.78%.
