No study has compared zero tillage with reduced tillage and conventional tillage practices for yam production on an Alfisol under a forest–savanna transition zone with humid tropical conditions. Hence, there is a need to study soil conditions that promote yam production in different ecological zones and soil types. These soil conditions are influenced by tillage, which is performed

using zero tillage Today, after the United States, Brazil has the second largest area cultivated using ZT — some 25.5 million hectares, or more than 60 per cent of the country’s cultivated surface. Although ZT was initially tested in the United Kingdom, it was the United States who adopted and further developed it in the early 1960s.
