Getting the focus right: production constraints for six major food crops in Asian and African farming systems
To determine the most important production constraints and associated yield losses for six major food crops in 13 farming systems with high poverty in Sub-Saharan Africa, South Asia and East Asia, surveys were conducted ...
Nitrogen and phosphorus capture and recovery efficiencies, and crop responses to a range of soil fertility management strategies in sub-Saharan Africa
This paper examines a number of agronomic field experiments in different regions of sub-Saharan Africa to assess the associated variability in the efficiencies with which applied and available nutrients are taken up by ...
Improving market access and agricultural productivity growth in Africa: what role for producer organizations and collective action institutions?
The history of producer organizations in sub-Saharan Africa (SSA) is a mixed one. In the past, producer organizations often failed to provide desired services due to dependence on government support, which led to heavy ...
Los cultivos de cobertura en la agricultura en laderas: Innovación de los agricultores con Mucuna
(CIMMYT; CATIE; IDRC, 1999)
Effect of intercropping maize and soybeans on Striga hermonthica parasitism and yield of maize
Striga hermonthica a major biotic constraint to cereal production can be controlled by trap crops. Soybean cultivars vary in ability to stimulate suicidal germination of the weed. An experiment was conducted to select ...
Assessing innovations lacking developed supply markets: A simple ex ante model applied to rock phosphate use in rice in West Africa
New technologies often lack a developed supply market, which makes it problematic to estimate future profitability. This paper develops a simple methodology to circumvent this problem based on the concepts of break-even ...
Herbicide applied to Imidazolinone resistant-maize seed as a Striga control option for small-scale African farmers
Striga is a major constraint to food production in Africa. Most technologies developed for the eradication of Striga asiatica from the United States are not adaptable to Africa. Imazapyr and pyrithiobac coated imidazolin ...
Improving irrigated rice production in the Senegal River Valley through experiential learning and innovation
Research facilitating farmer-researcher collaboration and experiential learning may provide the missing element to tailor crop management recommendations to meet farmers? needs. We tested different crop management systems ...
Yield, water productivity and nutrient balances under the system of rice intensification and recommended management practices in the Sahel
Consumer demand for rice in sub-Saharan Africa (SSA) is increasing faster than for any other cereal. Governments in the Sahel are responding by promoting double-cropping of irrigated rice in the region's river basins, ...
Reconstituting family transitions of Sahelian western Niger 1950-2000: an agent-based modelling approach in a low data context
This research analyses the impacts of the family organization on the diversity of income sources and the sustainability and the dynamics of rainfed farming systems of Sahelian Niger, through an individual-centred agent-based ...
