Diffusion and adoption of new rice varieties for Africa (Nerica) in the Gambia
Rice ( Oryza sativa ) is one of the most important cereal crops
cultivated in sub-Saharan Africa (SSA). It is ranked as the fourth most
important crop in terms of production after sorghum ( Sorghum bicolor
), maize ( Zea mays ) and millet ( Eleusine coracana ). The objective
of this study was to establish adoption rates, and their determinants,
of the New Rice Varieties for Africa (NERICA) in the Gambia. We used
data from a stratified sample of 600 rice farmers and applied the
Average Treatment Estimation (ATE) framework to establish rate of
adoption and associated factors. The results revealed that NERICA
adoption rate was barely 40% falling far below the expected 83%. The
shortfall was due to the incomplete stakeholder exposure to NERICA in
the period before 2006. The introduction of NERICA to villages was
found to be a significant determinant of both exposure and adoption of
NERICA varieties.Le riz ( Oryza sativa ) est l\u2019une des c\ue9r\ue9als les plus

Willingness to pay for biofertilizers among grain legume farmers in northern Ghana
Open Access Journal; Published online: 27 April 2018Background: The call for use of improved Soil Fertility Management (SFM) technologies is a prerequisite to increase agricultural productivity among farmers. This study assessed farmers’ willingness to pay (WTP) for selected financially rewarding biofertilizer technologies/packages for legume production in northern Ghana. Primary data was elicited from 400 grain legume farmers
selected from Northern and Upper West Regions of Ghana through a simple random sampling technique. The double bounded dichotomous choice (DBDC) format of contingent valuation approach was employed to elicit willingness to pay values and determinants of farmers WTP was evaluated using the maximum likelihood estimation procedure.
Results: The results showed that about 60%, 25% and 46% of soya, cowpea and groundnuts farmers were willing to pay for the selected biofertilizers (Biofix, BR3267 and Legumefix respectively) at prices not exceeding GHC 14.00, GHC 28.00 and GHC 20.00 per 0.2kg of the respective biofertilizers. Legume farmers in Northern Region were however willing to pay higher for the three biofertilizer technologies as compared to their counterparts in Upper West Region. For 0.2 kg each of Biofix, BR3267 and Legumefix, farmers in Northern Region were willing to pay approximately GHC 17.00, GHC 12.00 and GHC 23.00 respectively whereas those in Upper West Region were willing to pay GHC 14.00, GHC 9.00 and GHC 11.00 for the same quantity of each
biofertilizer. The study identified farming experience, FBO membership, awareness and previous use of biofertilizers as significant determinants of farmers’ willingness to pay for Biofertilizers.
Conclusion: Comparatively, mean prices farmers are willing to pay for these three technologies are below ex-factory prices, hence subsidizing the cost of production of these biofertilizers in the initial stages would be relevant for improving farmers’ uptake of these fertilizers. Sustained awareness creation through periodic education and sensitization by using FBOs as leverage points
is also highly recommended to improve farmers’ understanding of the concept of biofertilizer use
