The demand for maize increases annually due to urbanization and population growth (FAO, 2013).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although Nigeria produces over 7 million metric tons of maize per year, grain yield is low, leading to a deficit in total production. Poor soil fertility is a major constraint in the predominantly maize production areas of the Nigerian savannas. Fertilizer application is widespread and is required to increase maize production. The most commonly used fertilizer is NPK 15-15-15, the suitability of which is much debated for maize. Poor response to fertilizer application is an important constraint in expanding commercial maize production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The OCP-Africa fertilizer company in Morocco funded a project in 2017-2018 to develop affordable and efficient fertilizers to sustainably increase maize yields in Nigeria. The project is the largest in IITA that is funded by a commercial private organization. IITA collaborates with the Africa Soil Information Service (AfSIS) and with national partners Bayero University Kano (BUK), Institute of Agricultural Research (IAR), Zaria and National Agricultural Extension Research and Liaison Services (NAERLS); and with the Agricultural Development Programs (ADPs) of the relevant Local Government Areas (LGAs) for implementation. The project covers the whole maize belt of Nigeria, which measures around 225,000 square kilometers (Fig. 1). Developing new fertilizer formulations relevant for the area required characterization of the soils of the maize belt in terms of limiting nutrients, development and production of new fertilizers, and validation of new formulations in many trials across the area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"http:\/\/annualreport18.iita.org\/2020\/04\/20\/affordable-and-efficient-maize-fertilizers-for-nigeria\/\" target=\"_blank\" rel=\"noopener noreferrer\">Lire la suite<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Maize is the third most important food crop in Nigeria in terms of production after cassava and yam, with 31% used for feed and 12% for processing.
