The dominance of non-NERICA farmers in terms of average yield is not, however, uniform across gender. Indeed, Table 7.2 shows that when we differentiate between the men-headed households and women-headed households within each group, NERICA-adopting women have a slightly higher average yield than non-adopting ones for Benin (+308 kg/ha) and Cote-d’Ivoire where NERICA-adopting women-headed households (with 1.3 t/ha) obtained approximately twice of the mean yield of men-headed households (0.7t/ha). In Gambia, NERICA-adopting women-headed households also have higher mean yield than NERICA-adopting men -headed households by a difference of +350 kg/ha. This result may be explained by the appreciated implication of women in rice farming in these countries and for whom rice production and post-harvest activities are of high importance in terms of income generation. This contrast well with what is observed in the sample in Guinea where women-headed households are not well-represented in rice farming.

As discussed above, the differences in mean yield between NERICA-adopting and non-adopting farmers may be due to differences in observable and non-observable farmer socioeconomic and environmental characteristics. Table 7.3 shows the means and standard deviations of some observed socio-demographic characteristics of farmers in the two groups. The results of the t-test of difference of the group means and the Kolmogorov-Smirnov test for equality of two distributions also shown in the table indicate that compared to non-adopting ones, NERICA-adopting farmers are significantly more likely to live in PVS villages and participate in PVS trials in all of the four countries. In particular for Benin, NERICA-adopting farmers are significantly more likely to have more land available for rice production and higher household size. NERICA-adopting farmers in Cote-d’Ivoire are significantly more likely to be older, be of the Bete ethnic group, live in the forest zone and practice upland rice farming. On the other hand, they are significantly less likely to be of the Senoufo ethnic group and to practice lowland farming. NERICA-adopting farmers in Gambia are significantly more likely to be more experienced in upland rice cultivation. In Guinea, NERICA-adopting farmers are significantly more likely to have higher number of years of schooling, to belong to Soussou ethnic group, to have higher household size, to be female-gender and to be in contact with the institution Sassakawa Global 2000.Table 7.3Socio-demographics of NERICA adopters and non-adopters in the four countries
