4. Introduction Country brief
Area : km² Capital city : Yamoussoukro
Population : 20,8 millions inhabitants
per capita GDP : F CFA (US $ 1800)
GDP growth rate in 2008: +2,3 %
Inflation rate in 2008: +6,3 % (Source UEMOA: April 2009)

5. Introduction Importance of rice in Côte d’Ivoire
Domestic production in 2007 : tons of milled rice
Domestic consumption in 2007 : 1.5 million of milled rice
Almost half of domestic needs are imported

6. Introduction The national agricultural research system
CNRA is the sole national agricultural research institution.
It was established by decree as semi-autonomous private company with minority public shareholding in 1998.
CNRA is responsible for the bulk of technological research related to agricultural sector: food crops (rice, maize, …) perennial crops (cocoa, coffee, …) livestock and fishery

7. Methodology Sampling Random sampling
Sample size: 250 households (seed and rice surplus type marketing)
Sub sample size:
Field area measuring: 62 farms (including 313 individual rice plots)
Yield measuring: 62 farms with three replications by farm
Socioeconomic survey: 170 households

8. Methodology Measuring rice field area with GPSMAP 76S

24. Some local rice varieties

25. Conclusion Advantages of GPS use Socioeconomic difficulties
Easy to use
Good precision
Socioeconomic difficulties
Land pressure characterized by small rice field size
Women can not inherit land
Technical performance of rice cropping system
Low input system
Low yield that leads to low paddy production

26. Conclusion Seed production activities Some recommendations
Market opportunities for women
Seed market increases women income
Narrow seed market
Some recommendations
Help women access to production inputs (equipments, fertilizers, herbicides, …)
Emphasize participatory diffusion systems of improved varieties in rural area
