5. Mitigations to these constraints
• Conventional Breeding
- Developing tolerant varieties
• Plant Biotechnology
- Introducing novel genes into plants to develop
tolerant varieties
• Role of African Agricultural Technology
Foundation (AATF)
6. Role of AATF
• Not for profit organization based in Kenya
- Accesses proprietary and non-proprietary
agricultural technologies on royalty- free basis
- Forms partnerships with public & private
institutions globally to develop the technology
- Develop the technology with partners
- Deploy the technology to small-holder farmers in
Sub –Saharan Africa (SSA)
7. NEWEST RICE PROJECT
• Technology Provider: Arcadia Biosciences, USA
• Nitrogen Use Efficiency (NUE)
- source: Barley
• Water-use Efficiency (WUE)
- source: Bacteria protein
• Salt –tolerance (ST)
- source: Rice
• Transformation variety: NERICA-4
8. NEWEST RICE PROJECT
Product Development
- Efficacy testing of transgenic lines in confined field
trials (CFT)
- Locations (2): Ghana & Uganda
- 8 NUE lines, 8 Isogenic lines and NERICA-4 (control)
- Fertilizer rates: 30, 60, 90 Kg N/ha
- Two plantings to be done in 2013
- Data collection in progress
- NEWEST lines to be planted in 2014
9. NEWEST RICE PROJECT
NUE lines planted with 3 different fertilizer rates of
30, 60 & 90 kg N/ha in Ghana

12. Constraints on Rice farming
• Nitrogen deficiency
- Prohibitive fertilizer costs
- Unavailable
- Losses from the soil
• Drought
- Climate change
- Unpredictable weather patterns
- Recurrent
• Salinity occurs in coastal & irrigated soils
