This document discusses soybean production and utilization in Africa from the perspective of the International Institute of Tropical Agriculture. It outlines the importance of soybean for employment, income, nutrition, and sustainable agriculture. Key constraints to soybean production include lack of improved varieties, low yields, diseases, pests, and socioeconomic issues like unstable prices and lack of processing equipment and market information. The IITA's research activities focus on breeding higher-yielding varieties resistant to diseases and pests, developing sustainable production systems, and processing technologies. Their work also includes training farmers, developing partnerships, and transferring technologies to improve soybean production and utilization in Africa.

1. SOYBEAN PRODUCTION
AND UTILIZATION IITA PERSPECTIVE
International Institute of Tropical Agriculture
Ibadan, Nigeria

2. IMPORTANCE OF SOYBEAN IN
AFRICA
Soybean is important for three main
reasons:
 Employment and Income (farmers,
processors, market women)
 Nutrition and Health benefits (Protein,
Oil and Minerals, Vitamins)
 Role in sustainable agriculture (N2,
Org C, Striga)

3. CONSTRAINTS
⇒ Agronomic constraints
- Lack of inadequate supply of
improved varieties
- Low yields of farmers varieties
- Pod shattering
- Poor nodulation/N fixation
- Poor seed storability
- Diseases (FLS, Rust, BP, SMV)
- Insect pests (PSBs, defoliators)

4. ⇒⇒ Socio-economic constraintsSocio-economic constraints
- Unstable producer price
- Lack of inadequate market information system
- Inadequate information on knowledge of
processing & utilization technologies
- Lack of small scale processing equipment
- Consumers’ prejudice (bias) based on wrong
information about soybean

6. RESEARCH
♦ Raise grain yield levels
♦ Improved crop management system to optimise
yields (crop husbandry IPM for diseases & pests)
♦ Breed for quality traits in grain & stover (protein/oil,
minerals vitamins)
♦ Breed for high biomass production, high % Ndfa,
P-use efficiency and cereal Striga stimulation
 Development and promotion of new soy fortified
local and exotic recipes
♦ Development of in-expensive small-scale
processing equipment

PROGRESS IN VARIETAL IMPROVEMENT

8. Technology Transfer
 Massive campaign on uses and benefits
from soybean consumption
 Training in local household/small-scale
processing and methods of incorporating
soybean in local dishes.
 On-farm adaptive/validation and demonstration
of production technologies
 Establishment of market information system
on soybean to link producers with markets.

9. PARTNERSHIPS
⇒ Stakeholder networking
⇒ Establish Market Information
Systems
⇒ Stakeholder capacity building

10. Soybean varieties with high Grain
and biomass developed
