“…Similar results have been reported by studies undertaken in Uganda on determinants of farm-level adoption of cultural practices for Banana Xanthomonas Wilt Control [49]. In addition, agro-ecological zone has been shown to influence the performance of banana varieties [50]. This trade orientation significantly contributes to farm revenue and probably the likelihood in TCB participation.…”

In this study cross-section data was used to analyze the effect of farmers' demographic, socioeconomic and institutional setting, market access and physical attributes on the probability and intensity of tissue culture banana (TCB) adoption. The study was carried out between July 2011 and November 2011. Both descriptive (mean, variance, promotions) and regression analysis were used in the analysis. A double hurdle regression model was fitted on the data. Using multistage sampling technique, four counties and eight sublocations were randomly selected. Using random sampling technique, three hundred and thirty farmers were selected from a list of banana households in the selected sub-locations. The adoption level of tissue culture banana (TCB) was about 32%. The results also revealed that the likelihood of TCB adoption was significantly influenced by: availability of TCB planting material, proportion of banana income to the total farm income, per capita household expenditure and the location of the farmer in Kisii County; while those that significantly influenced the intensity of TCB adoption were: occupation of farmers, family size, labour source, farm size, soil fertility, availability/access of TCB plantlets to farmers, distance to banana market, use of manure in planting banana, access to agricultural extension services and index of TCB/non-TCB banana cultivar attributes which were scored by farmers. Compared to West Pokot County, farmers located in Bungoma County are more significantly and likely to adopt TCB technology. Therefore, the results of the study suggest that the probability of adoption and intensity of the use of TCB should be enhanced. This can be done by taking cognizance of these variables in order to meet the priority needs of the smallholder farmers who were the target group. This would lead to alleviating banana shortage in the region for enhanced food security. Subsequently, actors along the banana value chain are encouraged to target the intervention strategies based on the identified farmer, farm and institutional characteristics for enhanced impact on food provision. Opening up more TCB multiplication centres in different regions will make farmers access the TCB technology for enhanced impact on the target population.

“…This can be further illustrated by the dessert cultivar 'Lai' which produced a 12kg bunch and an average yield of 9 t/ha in comparison with the common local dessert cultivars 'Ikigurube' and 'Kamaramasenge' grown in Burundi which produce bunches of 9.5 kg and 8.0 kg and a yield of 8.1 t/ha and 8.0 t/ha, respectively (Kamira et al, 2013). A similar observation was made in DRC, where the cultivars 'Bira', 'Lahi', 'Lai' and 'Pelipita' generated annual yields (7-15 t/ha) higher than the overall national annual yield of bananas (4.6 t/ha) (Dowiya et al, 2009).…”

Vitamin A deficiency (VAD) is a major global health issue, contributing to morbidity and mortality. East and Central Africa face VAD prevalence that exceeds the World Health Organization (WHO) threshold of 15%. In Burundi and the Democratic Republic of Congo (DRC), VAD prevalence is greater than 43% in rural communities. Promoting vitamin A-rich foods (including banana) is an effective and sustainable strategy to address VAD in poor rural communities. Supported principally by HarvestPlus over more than a decade, banana researchers have been evaluating the performance of high provitaminA banana cultivars to address this challenge. This study evaluated the agronomic performance of six provitamin A-rich banana cultivars originally from outside Burundi and Eastern DRC. Growth and yield parameters were collected for the first, second and third crop cycles. Results revealed that growth and yield parameters were significantly affected by the interaction between sites and cultivars (P<0.05). Banana cultivar yield was also influenced by the combined effect of bunch weight and crop cycle duration. The most promising cultivars in terms of yield were 'Apantu-AAB', 'Lahi-AAB', 'Lai-AA', 'Bira-AAB' and 'Pelipita-ABB' across all sites and crop cycles. This indicates that although ecological factors could have influenced their performances over sites, genotype could be the most important influencing factor. These evaluations provide hard evidence of the high potential for adoption of the most promising cultivars by the local community members to boost (pro) vitamin A consumption and effectively eliminate VAD.

“…Yangambi Km5 is associated with the loss of Kayinja (the main beer cultivar) following the Fusarium wilt outbreak about ten to twenty years ago (Ocimati et al, 2013). The FHIA group of hybrid varieties was introduced about 20 years ago in the region (Gaidashova et al, 2010, Kamira et al, 2013, and has been dominant in both the formal and informal seed sector. It is notable however that FHIA dominance could also be associated with its integration into the local production objectives and multiple uses to which they have been put, and clear production-linked genetic gains provided by this group of cultivars in terms of market value and ecological adaptability (Ocimati et al, 2013).…”

“…The planting material for banana and other vegetatively propagated crops (VPCs) is often bulky and may readily spread pests and diseases to new plantings (Almekinders et al, 2019; Bentley et al, 2018; Jacobsen et al, 2019). In developing countries, seed exchange is largely local and unregulated, which results in increased risk of disease transmission (Bentley et al, 2018; Biemond et al, 2013; Kumar et al, 2011; Simbare et al, 2020) and reduced probability of sharing high quality seed (Simbare et al, 2020).…”

Banana seed exchange networks in Burundi – Linking formal and informal systems

Seed system network analysis can reveal exchange connections between stakeholders and test scenarios such as those of seed systems shocks. We investigated the seed exchange network structure, disease surveillance risk, and gender contribution in Burundi, under two banana disease risk scenarios. Two sites where banana bunchy top disease (BBTD) is endemic in Cibitoke Province were compared with a site free of the disease in Gitega Province. All sites had formal seed interventions using community nurseries. A quantitative survey on seed sharing was done followed by a qualitative evaluation through focus group discussions. Banana seed sourcing options were fewer in the disease-free site, which also had higher cultivar diversity. Most farmers sourced seed informally within a three-kilometer radius. Seed sharing within and between villages was based on social and family linkages, especially for women. The interaction between the formal system and informal seed exchange was more active where new cultivars, or better seed quality was expected. The BBTD endemic region had lower seed quality assessment stringency. Farmers used both direct mother plant assessment and seed source reputation in seed evaluation. The formal banana seed systems are sources of new varieties, and trusted for clean seed but the informal system was still used as a main source of seed, especially local cultivars. Assessing disease surveillance scenarios shows women in a weaker position for healthy seed acquisition. Identifying the roles of individuals in seed systems can support decision processes for seed interventions in vegetatively propagated crops.
