“…The lower overall fruit yield of the local plantains could also be due to higher susceptibility to pests and diseases compared with hybrid plantains. The average bunch weight of each improved genotype reported in this study is higher than that reported from farmers' fields in Cameroon (Banful et al, 2008;Dépigny et al, 2019;Pierrot et al, 2002). It is however below the average yield of 24.7 kg recorded in the plantain Optim trial done by CARBAP (S. .…”

Plantain is one of the major staples contributing to food security and income generation in West and Central Africa. Local cultivars in Cameroon are susceptible to pests and diseases causing severe losses in plantain production. This study aimed at evaluating the agronomic performance and producer's perception of plantain hybrids in the humid forest of Cameroon. Field trials were established in a completely randomized block design with eight genotypes and three replicates. Data on pest and disease as well as farmer perception were collected over two growing cycles. These genotypes included seven improved and one local genotype (check). Improved genotypes were highly tolerant to the Black Sigatoka disease compared to local plantain. While root necrosis index was above 50% in local varieties, indices below 25% were recorded in hybrids. Weevil severity in local was higher (55.0 ± 5.2%) compared to 21.0 ± 4.6% to 28.5 ± 3.2% in improved plantains. Average bunch weight was higher for FHIA 21 with 17.9 ± 0.7 kg in the first and 19.7 ± 0.3 kg for the second cycle, while those of the local Ebang were 9.6 ± 0.5 kg and 12.8 ± 0.9 kg, respectively. FHIA 21 and CRBP 568 were the preferred varieties by farmers (68.8% and 56.3% acceptance) from an agronomic perspective. The consumers' preferences for all the genotypes varied with types of cooking. The implications of these findings for adoption by farmers and consumers as well as for the promotion of the plantain sector in central Africa are discussed.

“…In light of the lack of a sufficient quantity of quality plantain material (suckers), farmers collect suckers from old plots that are lying fallow (80% of suckers), thereby transferring significant quantities of contaminated planting material to healthy plots. Production cycles last only 4 years and produce low yields, with losses amounting to more than 50% of production after the third cycle, resulting in a shift in the production area (Pierrot et al 2002).…”

The food security challenges faced by populations in sub-Saharan Africa and the fact that extensive production systems are reaching their limits in the food-producing agricultural chain have increased the need to accelerate technological innovation toward the ecological intensification of agricultural production systems. Here, a review of the research conducted on plantain bananas (Musa paradisiaca) in Cameroon since 1988 revealed how institutional innovation has enabled the hybridization of different research forms- such as fundamental, systems, and action research-and reinforced the organizational innovation required for technical change. We found that impact evaluation underlined the complementarity between the increases in productivity and income in rural areas, as well as the production of human and social capital and the protection of forest resources.

“…Former results [3] showed that, under smallholder conditions, losses of banana plants before harvest often surpass 30% of total banana plants initially planted. To get correct figures concerning yields, a sufficient number of bunches must be observed (20 to 30) and, consequently, other banana plants of the same variety, cycle and development stages must replace the ones lost.…”

A multidisciplinary monitory centre by smallholders in Cameroon to identify factors limiting plantain production.Abstract --Introduction. In Cameroon, plantain plays a major role in food security. An increase in production is necessary to satisfy the demand. Since April 2002, CARBAP has supported a monitory centre of plantain production. The main objective is to prioritise studies of production constraints and characterise commercialisation strategies, in order to improve profitability for smallscale farmers. Materials and methods. Eighteen plots were identified within farms that represent the agro-ecological and socio-economic diversity of the region. Plots were considered as the sampling unit for agronomic and pathogenic constraints analysis. Farms were considered as the sampling unit used in the socio-economic constraint analysis. For each plot, a regular survey of 50 banana plants and agronomic practices was carried out. A survey of each farm was also set for the observation of production conditions thanks to the participation of smallholders. Results. It is possible to distinguish smallholders with different levels of diversification towards plantain production. Agronomic results in the plots surveyed were judged thanks to parameters of growth, yield and pest infestation. Good/bad results on young/older plots were basically distinguished. These divisions of individuals are influenced by initial factors (varieties available for planting, former crops in the plot), means available (inputs) and technical skills in plantain cultivation. Conclusion. This method allows the detection of indicators of diversification towards plantain cultivation and allows one to check the sustainability of such strategies. It is possible to propose improved technical practices. They will be used for further local studies aimed at improving the plantain production.Cameroon / Musa (plantains) / surveying / economic analysis / yield components / fungal diseases / parasitism Un observatoire multidisciplinaire auprès de petits exploitants au Cameroun pour identifier les facteurs limitant la production de plantain.Résumé --Introduction. Au Cameroun, le plantain joue un rôle important pour la sécurité alimentaire. Une augmentation de la production serait nécessaire pour satisfaire la demande. Depuis avril 2002, le CARBAP maintient un observatoire de la production de plantain. L'objectif principal est d'étudier en priorité les contraintes de production et de caractériser les stratégies de commercialisation, afin d'améliorer la rentabilité de cette culture pour les petits exploitants. Matériel et méthodes. Dix-huit parcelles de terrain ont été identifiées dans des fermes représentatives de la diversité agro-écologique et socio-économique de la région. Ces parcelles ont été considérées comme unité d'échantillonnage pour l'analyse agronomique et celle des contraintes parasitaires. Les fermes ont été considérées comme unité élémentaire utilisée pour l'analyse des contraintes socio-économiques. Pour chaque parcelle, un suivi régulier de 50 pla...
