Publication - Characteristics of maize cultivars in Africa: How modern are they and how many do smallholder farmers grow?(Springer Verlag, 2017) Abate, T.; Fisher, M.; Abdoulaye, T.; Kassie, G.; Lunduka, Rodney; Marenya, P.P.; Asnake, W.Maize is the most important cereal and most widely cultivated staple that plays a key role in the food security of sub-Saharan Africa (SSA). Although some countries have achieved significant gains in maize productivity, the SSA average yields are far below what could be obtained with improved cultivars under good crop management. Low cultivar turnover is one among many contributing factors to low maize yields in SSA. At present, there is a critical knowledge gap on the identity, number, and age of maize cultivars currently grown by smallholder farmers on the continent. This study revealed that nearly 500 maize cultivars were grown in 13 African countries surveyed in the 2013/2014 main crop season. Sixty-nine percent of the cultivars each occupied <1% of the total maize area; only two cultivars occupied >40% and four occupied >30% area. Approximately 32% of all the cultivars were hybrids, 23% were improved open-pollinated varieties (OPVs), and 46% were locals. Eastern Africa (EA) and southern Africa (SA) accounted for about 43 and 38%, respectively, of all the cultivars reported, whereas West Africa’s (WA) share was 19%. The average area planted to modern cultivars in the surveyed areas was estimated at 57%—with EA, SA, and WA estimates of 82, 55, and 36%, respectively; however, increased adoption was not necessarily always related to improved productivity, as the latter depends on many additional factors. Each household planted an average of 1.781 cultivars (range 1–8). The overall weighted average age of the cultivars was 15 years, with hybrids and OPVs being 13 and 18 years, respectively. Conclusions: Maize variety turnover in SSA is slower than what is practiced in the USA and other world regions such as Latin America and Asia. The substantial variations among regions and countries in all parameters measured suggest a tailored approach to mitigation interventions. Findings of this current study pave the way for replacing the old cultivars with more recent releases that are tolerant or resistant to multiple stresses and are more resilient.
Publication - Maize variety options for Africa: Nigeria(CIMMYT, 2015) Abate, T.; Menkir, A.; Badu-Apraku, B.; Abdoulaye, T.; Abdullahi, I.; Ogunble, A.; Onyibe, J.E.; Ado, S.; Olaoye, G.
Publication - Maize variety options for Africa: Ghana(CIMMYT, 2015) Abate, T.; Badu-Apraku, B.; Menkir, A.; Abdoulaye, T.; Obeng-Antwi, K.Maize is top of all cereals and other staples in Ghana. The increased production has been a result of increased area expansion rather than increased yield gains.

Publication - DTMA highlights for 2012/13(CIMMYT, 2013) Abate, T.; Menkir, A.; MacRobert, J.; Kassie, G.; Abdoulaye, T.; Setimela, P.; Badu-Apraku, B.; Makumbi, D.; Magorokosho, C.; Tarekegne, A.T.Launched in 2007, the Drought Tolerant Maize for Africa (DTMA) project aims to mitigate drought and other constraints to maize production in sub-Saharan Africa (SSA). It targets to increase yields by 20 to 30%, benefiting 30-40 million people in 13 countries of SSA – Angola, Malawi, Mozambique, Zambia, and Zimbabwe (in southern Africa); Ethiopia, Kenya, Tanzania, and Uganda (eastern Africa); and Benin, Ghana, Mali and Nigeria (West Africa). Together, these countries account for nearly 75% of all area planted to maize in SSA. The project brings together men and women farmers, research institutions, extension specialists, seed producers, farmer community organizations, and non-government organizations. It is jointly implemented by the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute for Tropical Agriculture (IITA), in close collaboration with national agricultural research systems (NARS) in participating nations. Each sub-region conducts its own annual review and planning meetings according to its objective conditions. The overall annual review and planning meeting for the project is held towards the end of September each year. Highlights presented in this publication are the result of the annual review and planning meeting held on 22-26 September 2013. The reports are presented in two broad categories. The first part deals with the overview of work carried out between October 2012 and September 2013 and jointly prepared by CIMMYT/IITA scientists. Progress in variety development and socioeconomics work is presented separately for each sub-region whereas reports for seed production and delivery are presented in one report for eastern and southern Africa and another for West Africa. Cross-cutting topics, including the overall project highlights, maize lethal necrosis, gender, and communication are also presented in the first category of reports. The second category of reports are prepared by the NARS scientists and presented for each country. Each report here summarizes the major activities carried out across the three objectives – breeding, seed production and delivery, and socioeconomics – for the reporting period.
