This presentation describes dissertation work focusing on conservation agriculture production systems for smallholders and limited input farmers. The research design focuses on the conversion of previously conventionally tilled fields to a no till system and subsequently compares different mulch applications including straw and leguminous plants. The main objective of the research was to study whether herbicide free systems could be productive. Such findings may also have promising impacts for organic farmers.
