Effects of Tillage Practices on Soil Properties under Maize Cultivation on Oxic Paleustalf in South Western Nigeria

摘要

A study was conducted to determine the effect of tillage practices on soil properties under maize cultivation in savanna ecosystem of South Western Nigeria. The tillage systems evaluated were zero, convectional and traditional tillage systems. The results showed that there is a significant difference in soil parameters and crop morphologies at p , for crop growth and best performance of crop followed by conventional and no-tillage system in the area are studied respectively. The significant difference in yields adduced to lower bulk density, higher water holding capacity and porosity which increased plant root proliferation and optimal utilization of soil nutrients under tilled methods. Hence tillage methods have the capability to increase production while no-tillage is better under long term production for sustainable land use.
