Problem

  • Erratic Rainfall Patterns and Water Scarcity: The variability in precipitation poses a significant challenge to agricultural productivity, as crops like maize require sufficient water for optimal growth and development.
  • Challenges Associated with Drought Resilience: Traditional maize varieties often lack sufficient resilience to withstand prolonged drought conditions, resulting in decreased yields and economic losses for farmers.
  • Limited Access to Improved Varieties: Farmers in Sub-Saharan African countries face challenges in accessing improved maize varieties due to limited investments in the seed production sector.
  • Low Productivity in Maize Farming: Conventional maize varieties may not be well-suited for the diverse climatic and soil conditions found in Sub-Saharan Africa, leading to low productivity in maize farming.
  • Food and Nutritional Insecurity: Limited access to improved maize varieties can contribute to food and nutritional insecurity in the region, affecting both the quantity and quality of harvested grain.

Solution

  • TEGO, improved maize varieties with enhanced drought tolerance
  • Breeding of maize hybrids with high yield (20-35% yield increase) potential under drought stress conditions
  • Promotion of sustainable agricultural practices, including conservation agriculture and integrated soil fertility management
  • Provision of training and extension services on climate-smart agricultural practices
  • Empowerment of smallholder farmers through access to improved maize varieties and knowledge resources
  • These varieties are specifically developed to perform well in diverse climatic and soil conditions.

Key points to design your project

This technology addresses water stress in Sub-Saharan maize production, improving productivity and resilience to adverse rainfall. It contributes to climate resilience and SDGs, particularly in food security and poverty reduction. Gender-inclusive access further promotes equitable agricultural development.

To integrate this technology into your project, and create a list of project activities and prerequisites and plan these activities: 

  • Considering the technology cost of 0.8 to 1.2 USD per kg and a requirement of 25 kg per ha, estimate the quantity of seeds needed for your project. 
  • As the technology is available in Kenya, Malawi, Mozambique, Nigeria, South Africa, Tanzania, Uganda, Zambia and Zimbabwe, include the delivery cost to the project site and account for import clearance and duties if relevant. 

A team of trainers could provide training and support during project installation. Include the cost for training and post-training support for using the technology.

Communication support for the technology should be developed (flyers, videos, radio broadcasts, etc.)

For better optimization of the improved maize variety, it is recommended to associate this technology with Imazapyr resistant maize for Striga management (IR maize), Specialized pre-plant fertilizer blending and N topdressing, Maize-legume rotation and intercropping. 

To implement the technology in your country, you could collaborate with agricultural development institutes and seed multiplication companies.

According to different countries, here are the suitable individual varieties.

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.
