Maize Research Brief
Maize remains the staple food crop for majority of households. The AMRI-Katumani maize program was started in 1966 with mandate to develop maize varieties suited for drylands ecologies and therefore contribute to improved food security. Some of the outputs of the program over the years include development and deployment of the world famous Katumani Composite B (KCB), with desirable characteristics of early maturity and drought escaping. The program also carries out research on good agronomic practises for improved maize yields. The mandate region is challenged with various constraints which include unreliable rainfallranging 800-1200mm which is unevenly distributed, among other constraints. These lower the potential maize yields of estimated 3-5 tonnes per hectare to the recorded 0.5-2.0 t/ha.
