  • Dependence on Rainfall: Over 90% of African maize farming is rainfed, leaving crops vulnerable to unpredictable weather patterns.
  • Yield Instability: Conventional varieties are highly sensitive to water availability, leading to inconsistent yields.
  • Crop Failure Risk: Insufficient rainfall can result in complete crop loss, jeopardizing livelihoods.


  • Enhanced Resilience: DTMA and WEMA outperform conventional varieties under various water stress levels.
  • Increased Productivity: Adoption of these varieties leads to substantial increases in maize grain production.
  • Improved Crop Resilience: Crops become more robust, with heightened resistance to dry spells and low rainfall.
