Assessment of bambara groundnut landraces for resistance to Cowpea aphid borne mosaic virus
International Journal of Biological and Chemical Sciences, 2020Co-Authors: N’golo Moussa Konate, Essowé Palanga, Adjima Ouoba, Hervé Nandkangre, Théodore Ouedraogo, Mahama Ouedraogo, Mahamadou SawadogoAbstract:Bambara groundnut ( Vigna subterranea ) is an important seed legume in Burkina Faso. It provides a well-balanced diet and many other benefits for populations, especially in rural areas. Despite all these advantages, bambara groundnut cultivation remains subject to many constraints. One of the most important of them is viral diseases. This study was conducted in order to identify from Burkina Faso bambara groundnut landraces, some resistant genotypes to Cowpea aphid-borne mosaic virus (CABMV). In this study, 20 bambara groundnut landraces collected from three climatic zone of Burkina Faso were tested. According to their level of sensitivity to the CABMV isolate tested we obtained two groups of genotypes: G1 and G2. After retroinoculation, only six landraces, namely E119, E117, E105-a from Sahelian zone and E53-a, E103 and E97 from Sudan-sahelian zone, showed a resistance to the CABMV isolate. These results could be used to develop control strategies against viral diseases. Keywords: Vigna subterranea , Burkina Faso, CABMV, viral diseases, susceptibility

Metagenomic-based screening and molecular characterization of cowpea-infecting viruses in Burkina Faso
PLOS ONE, 2016Co-Authors: Essowé Palanga, Romain Ferdinand, Jean Zabré, Zakaria Bouda, James Bouma Neya, Darren P. Martin, Emmanuel Fernandez, Daniel Gargani, Denis Filloux, Mahamadou SawadogoAbstract:Cowpea, (Vigna unguiculata L. (Walp)) is an annual tropical grain legume. Often referred to as “poor man’s meat”, cowpea is one of the most important subsistence legumes cultivated in West Africa due to the high protein content of its seeds. However, African cowpea production can be seriously constrained by viral diseases that reduce yields. While twelve cowpea-infecting viruses have been reported from Africa, only three of these have so-far been reported from Burkina Faso. Here we use a virion-associated nucleic acids (VANA)-based metagenomics method to screen for the presence of cowpea viruses from plants collected from the three agro-climatic zones of Burkina Faso. Besides the three cowpea-infecting virus species which have previously been reported from Burkina Faso (Cowpea aphid borne mosaic virus [Family Potyviridae], the Blackeye cowpea mosaic virus—a strain of Bean common mosaic virus—[Family Potyviridae] and Cowpea mottle virus [Family Tombusviridae]) five additional viruses were identified: Southern cowpea mosaic virus (Sobemovirus genus), two previously uncharacterised polerovirus-like species (Family Luteoviridae), a previously uncharacterised tombusvirus-like species (Family Tombusviridae) and a previously uncharacterised mycotymovirus-like species (Family Tymoviridae). Overall, potyviruses were the most prevalent cowpea viruses (detected in 65.5% of samples) and the Southern Sudan zone of Burkina Faso was found to harbour the greatest degrees of viral diversity and viral prevalence. Partial genome sequences of the two novel polerovirus-like and tombusvirus-like species were determined and RT-PCR primers were designed for use in Burkina Faso to routinely detect all of these cowpea-associated viruses.

Productivity characteristics and development strategies of Sclerocarya birrea in Burkina Faso.
African Crop Science Journal, 2016Co-Authors: Pauline Bationo-kando, Mahamadou Sawadogo, B. Sawadogo, Z. Kiebre, P Kientega, Nerbéwendé Sawadogo, K.r. Nanema, Er Traore, J. D. ZongoAbstract:Sclerocarya birrea is a major component of agroforestry parks of Sudano Sahelian zones, which is exploited by rural populations in Burkina Faso. Recently, Sclerocarya birrea kernel marketing has increasingly developed in Ouagadougou (capital of Burkina Faso). This study aimed at evaluating the productivity, understanding the socio-cultural uses and socio-economic importance of S. birrea among local populations of Burkina Faso. The study has shown that S. birrea is a very fructiferous plant. The number of fruits yielded per tree ranges from 136 to 4256, with mean fruit weight and diameter that are respectively 12.66 and 26.71 mm. The number of kernels per fruit ranged from 1 to 3, with a mean diameter of 4.75 mm. All is not clearly separated to multi-purpose uses. All organs are used in 36 different ways. The pulp and kernels of the fruit are the only by-products marketed by women and mainly girls who dropped out of school.

Credit constraints and cropland allocation decisions in rural Burkina Faso
Land Use Policy, 2018Co-Authors: Mohamed Porgo, John K. M. Kuwornu, Pam Zahonogo, John Baptist D. Jatoe, Irene S. EgyirAbstract:Abstract This paper examined farm households’ cropland allocation decisions under credit constraints in rural Burkina Faso. A fully observed recursive mixed-process model was used to correct for the endogeneity of credit in farm households’ land allocation decisions in a multi-cropping context. Estimating the model with survey data collected in 2011 using the conditional mixed-process estimator, the results showed that credit constraints negatively affect farm households’ decision to allocate land to maize and cotton production in rural Burkina Faso. In contrast, at the expense of maize and cotton, credit constraints encourage farm households to allocate more land to sorghum and millet. The results also showed that socio-demographic characteristics and the use of animal traction significantly determined farm households’ land allocation decisions in rural Burkina Faso.

Credit constraints and labour allocation decisions in rural Burkina Faso
Agricultural Finance Review, 2017Co-Authors: Mohamed Porgo, John K. M. Kuwornu, Pam Zahonogo, John Baptist D. Jatoe, Irene S. EgyirAbstract:Purpose - Credit is central in labour allocation decisions in smallholder agriculture in developing countries. The purpose of this paper is to analyse the effect of credit constraints on farm households’ labour allocation decisions in rural Burkina Faso. Design/methodology/approach - The study used a direct elicitation approach of credit constraints and applied a farm household model to categorize households into four labour market participation regimes. A joint estimation of both the multinomial logit model and probit model was applied on survey data from Burkina Faso to assess the effect of credit constraint on the probability of choosing one of the four alternatives. Findings - The results of the probit model showed that households’ endowment of livestock, access to news, and membership to an farmer-based organization were factors lowering the probability of being credit constrained in rural Burkina Faso. The multinomial logit model results showed that credit constraints negatively influenced the likelihood of a farm household to use hired labour in agricultural production and perhaps more importantly it induces farm households to hire out labour off farm. The results also showed that the other components of household characteristics and farm attributes are important factors determining the relative probability of selecting a particular labour market participation regime. Social implications - Facilitating access to credit in rural Burkina Faso can encourage farm households to use hired labour in agricultural production and thereby positively impacting farm productivity and relieving unemployment pressures. Originality/value - In order to identify the effect of credit constraints on farm households’ labour decisions, this study examined farm households’ decisions of hiring on-farm labour, supplying labour off-farm or simultaneously hiring on-farm labour and supplying family labour off-farm under credit constraints using the direct elicitation approach of credit constraints. To the best of the authors’ knowledge, this study is the first to examine this problem in Burkina Faso.

Soil and Water Conservation in Burkina Faso, West Africa
Sustainability, 2018Co-Authors: Clement Nyamekye, Michael Thiel, Sarah Schönbrodt-stitt, Benewinde J.-b. Zoungrana, Leonard K. AmekudziAbstract:Inadequate land management and agricultural activities have largely resulted in land degradation in Burkina Faso. The nationwide governmental and institutional driven implementation and adoption of soil and water conservation measures (SWCM) since the early 1960s, however, is expected to successively slow down the degradation process and to increase the agricultural output. Even though relevant measures have been taken, only a few studies have been conducted to quantify their effect, for instance, on soil erosion and environmental restoration. In addition, a comprehensive summary of initiatives, implementation strategies, and eventually region-specific requirements for adopting different SWCM is missing. The present study therefore aims to review the different SWCM in Burkina Faso and implementation programs, as well as to provide information on their effects on environmental restoration and agricultural productivity. This was achieved by considering over 143 studies focusing on Burkina Faso’s experience and research progress in areas of SWCM and soil erosion. SWCM in Burkina Faso have largely resulted in an increase in agricultural productivity and improvement in food security. Finally, this study aims at supporting the country’s informed decision-making for extending already existing SWCM and for deriving further implementation strategies.
