Abstract
Influence of tillage on soil physical properties and three varieties of sesame (Sesamum indicum L.) in Ogbomoso, southwestern Nigeria
Highlights
Soil tillage is among the important factors affecting soil physical properties and crop yield
The proper use of tillage can improve soil related constrains, while improper tillage may cause a range of undesirable processes, e.g. destruction of soil structure, accelerated erosion, depletion of organic matter and fertility, and disruption in cycles of water, organic carbon and plant nutrient (Lal, 1993)
There was no significant difference among tillage practices on these soil properties
Summary
Soil tillage is among the important factors affecting soil physical properties and crop yield. Among the crop production factors, tillage contributes up to 20% (Khurshid et al, 2006). The proper use of tillage can improve soil related constrains, while improper tillage may cause a range of undesirable processes, e.g. destruction of soil structure, accelerated erosion, depletion of organic matter and fertility, and disruption in cycles of water, organic carbon and plant nutrient (Lal, 1993). There has been mixed reports from tillage research over the years. Many see the need to reduce the amount and intensity of tillage operations to reduce erosion, improve soil structure, and ease flooding by increasing the infiltration of water into the soil water system by quantitatively characterizing soil structural properties (Braudeau et al, 2004; Braudeau and Mohtar, 2008)
