DTMA & WEMA: Drought Tolerant Maize Varieties and Water Efficient Maize Varieties

Enhance farm's resilience with DTMA and WEMA maize varieties, ensuring consistent yields even in unpredictable weather.

These seed technologies, developed through conventional and biotechnological methods, bolster the maize plant's ability to withstand acute soil drying and low water supply. They outperform traditional varieties under various levels of water stress, offering resilience in both dry and intermittently wet climates.

Problem

  • 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.

Solution

  • 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.

Scaling Readiness describes how complete a technology’s development is and its ability to be scaled. It produces a score that measures a technology’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.
