“…Attaining formal education has been strongly correlated with adoption of management practices (Kikulwe and Asindu, 2020;Ebewore, 2016). In our study, 22.7% of the respondents had never attained any formal education, implying that management practices devised to curtail Fusarium wilt, need to be simplified in a more userfriendly manner and employ practical means like farmer field schools.…”

The study aimed at understanding the spatial distribution of Fusarium wilt (FW) in different banana growing regions, ascertain the effect of management practices and plantation age on FW incidence, as well as investigate farmers' knowledge regarding the symptoms and spread of FW in Uganda. Individual interviews were conducted in 119 farms using a pre-tested questionnaire and field observations during a survey in major banana growing regions. Results indicate that FW is widely distributed across the banana growing areas with more occurrences (70%) in Kapchorwa district and majority of respondents (63.4%) reported increasing disease prevalence. A chi-square test performed revealed significant association between FW incidence and plantation age with more incidences (51.6%) recorded in older plantations (>20 years of establishment) than newly (1-5 years) established ones (11.1%). FW incidence was significantly associated with plantation management with higher incidences (86.9%) recorded in well managed plantations. Half of interviewed farmers could explain and distinguish symptoms associated with FW from other diseases, but only 38.4% of these could tell how the disease spreads; thus, a need for more concerted efforts in building the capacity of farmers to identify the symptoms and spread of FW for effective management program. We identified preliminary evidence that field abandonment is sometimes used as a last option for coping up with FW. Understanding the mechanism behind this requires more detailed research as well as establishing how farmers are managing FW culturally.

“…Overall, there has been a significant number of scientific papers on promotion of biofortified OFSP and quality seed (see Meenakshi et al 2010;Ulimwengu et al 2011;Etumnu 2016;Adesina et al 2017;Mwiti et al 2020;Naico et al2020). Several studies have used various methods ranging from Choice Experiments (CE), Contingent Valuation Methods and Hedonic Pricing which are hypothetical (see Masumba et al 2007;Kikulwe et al 2020;Meenakshi et al 2010;Naico et al 2010, Mwiti et al 2020. For instance, the hypothetical discrete choice experiments do not include monetary exchanges, making it difficult to account for hypothetical bias (Steur et al 2016).…”

Farmers’ demand for quality and nutritionally enhanced sweetpotato planting material: Evidence from experimental auctions in Rwanda

2021

Most farmers source sweetpotato vines from neighboring farmers or from cuttings taken from their own plots during the previous season. In the absence of "clean" vines prepared with more attentive production practices, farmer-to-farmer vine exchanges and own-saved vines tends to encourage the accumulation of pests and diseases that ultimately affect yields. In addition, the perishability and bulkiness of its primary propagation material -vines -there is relatively little articulated demand for vines through either market or non-market exchanges. In addition, demand for nutritionally rich variety and biofortified crop orange-fleshed sweetpotato (OFSP) is limited because of multiple factors including farmers' unfamiliarity with the product and its novel attributes such as its high beta carotene content, the search costs incurred in locating the product, and information asymmetries between buyer and seller about the quality and performance of the product. We investigate demand for quality vine and nutritional attribute of the crop using a second price experimental auction approach by determine the premium price farmers are willing to pay for these attributes and investigate drivers of demand. In the absence of information on the source of vines, maturity and resistance to diseases, farmers are willing to pay a premium of about 35 Rwandan Francs for high quality vines sourced from decentralized vine multipliers. However, on provision of information on the source of vines, maturity and resistance to diseases of the vines, the premium price increases significantly to 133.71 Rwandan francs and to 107.22 Rwandan Francs after provision of visual information depicting the performance of the vines in demonstration plots. The premium price also increases significantly for vines sourced from neighbors to about 74.35 Rwandan francs, which further increases to 151.53 Rwandan francs when nutrition information is provided to the farmers. The study also revealed that demand for high quality vines is correlated with sex of household head, sex of the respondent, age of the respondent in years, household size, membership in a farmer organization, information from neighbors/other farmers, access to marshland, females make agriculture decisions in the household among other factors. In terms of policy, there is need to promote importance of quality vine and nutritional value of OFSP through sensitization on the field demonstration and nutritional values.

“…Banana and plantains are important food crops among many communities in the developing countries around the world (Scott, 2021). The annual global production of banana and plantains has been estimated at about 145 million metric tons (Ploetz and Evans, 2015;Rocha et al, 2021), of which around 30% comes from Africa (Kikulwe and Asindu, 2020). Disease complexes involving plant-parasitic nematodes and Fusarium of Banana Complex (FOBC) remain a major threat to banana production and hence food security in Africa and many other regions around the world (Maryani et al, 2019;Rocha et al, 2020;Bedoya et al, 2021).…”

Endosphere and rhizosphere microbes offer plant growth promotion and pest suppression ecosystem services in banana-based agroecosystems. Interest has been growing towards the use of such beneficial microbes in protecting vulnerable tissue culture banana plants against pathogens such as Radopholus similis and Fusarium oxysporum. A screenhouse experiment with potted tissue culture banana plants was conducted using sterile and non-sterile soil to investigate the effect of soil biota on R. similis and F. oxysporum strain V5w2. Plants grown in non-sterile soil had lower damage and R. similis density in roots and rhizosphere, while most plant growth-related parameters including root freshweight, shoot freshweight, total freshweight, plant height, and leaf size were larger compared to those from sterile soil. Shoot dryweight and Mg content were higher in plants from sterile soil, while their leaves developed discolored margins. R. similis-inoculated plants in sterile soil were smaller, had more dead roots, higher nematode density, and produced fewer and smaller leaves, than those from non-sterile soil. For all plant growth-related parameters, nematode density and root damage, no differences were recorded between controls and F. oxysporum V5w2-inoculated plants; and no differences between those inoculated with R. similis only and the ones co-inoculated with the nematode and F. oxysporum V5w2. Banana roots inoculated with F. oxysporum V5w2 were lighter in color than those without the fungus. Independent or combined inoculation of banana plants with F. oxysporum V5w2 and R. similis resulted in lower optical density of root extracts. In vitro assays indicated the presence of Fusarium spp. and other root endophytic microbes that interacted antagonistically with the inoculated strain of F. oxysporum V5w2. It is concluded that, soil sterilization eliminates beneficial microbes that provide natural pest suppression ecosystem services against R. similis and F. oxysporum in the endosphere and rhizosphere of tissue culture banana plants. I recommend the integration of microbiome conservation into tissue culture technology through the proposed “Tissue Culture Microbiome Conservation Technology.”
