Despite its importance, the average maize grain yields are still low in farmers\u2019 fields in the region due to constant exposure to recurrent drought, parasitic weeds (primarily\u00a0<em>Striga hermonthica)<\/em>, diseases, insect pests, inappropriate crop management practices, inadequate input use, and institutional factors. The Drought Tolerant Maize for Africa (DTMA) project was launched in 2006 to reduce vulnerability and improve food security through the development of maize hybrids and open-pollinated varieties (OPVs) with stable yields and enhanced tolerance for drought, resistance to\u00a0<em>Striga<\/em>\u00a0and major diseases prevalent in Eastern, Southern, and Western Africa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The DTMA Project financed by the Bill &amp; Melinda Gates Foundation and the Howard G. Buffet Foundation (HGBF) was run in three phases (2006-2015). It was jointly implemented by the International Center for Maize and Wheat Improvement (CIMMYT) and IITA in partnership with the national agricultural research and extension systems (NARES), private seed companies, community based organizations (CBOs), nongovernmental organizations (NGOs), and universities in 13 target countries across Africa, including Ethiopia, Kenya, Tanzania, Uganda, Angola, Malawi, Mozambique, Zambia, Zimbabwe, Benin, Ghana, Mali, and Nigeria. The first two phases of this project focused primarily on product development, testing, registration, and release through building of the required partnerships with both public and private sector institutions while strengthening their capacity to promote and deploy stress resilient products to farmers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"http:\/\/annualreport18.iita.org\/2020\/04\/20\/stress-resilient-maize-varieties-for-african-farmers-2\/\" target=\"_blank\" rel=\"noopener noreferrer\">Lire la suite<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Maize has emerged in the last three decades as an important food security and income generating crop for millions of people in sub-Saharan Africa (SSA).
