Upland maize production systems: Strategies for sustainability

Market forces in Southeast Asia have encouraged the proliferation of Hybrid Maize (Corn) production systems among marginalized smallholder farmers throughout upland areas. This presentation will describe that system and how the system can become more efficient in order to increase financial return and nutrient use efficiency. In addition, options for crop diversification will be discussed. The focus will be on Southeast Asian upland systems but will also include comparable examples from Africa and Central and South America.
