“…Recently, with strong fluctuations in coffee and tea prices, banana has also gained popularity as a cash crop in some regions. However, banana yields have decreased in Kenya and other countries of East Africa since the 1970s, partly due to pests, diseases, and poor crop management (Dubois et al, 2006;Kahangi, 2010;Njuguna et al, 2010).…”

“…Considering Kenya as a whole, less than 10% of all banana farmers have adopted TC so far, although in the Central and Eastern Provinces, where most of the dissemination programs started, adoption rates are already higher (Njuguna et al, 2010). The TC adoption process is relatively slow for two reasons.…”

“…While there is some debate about the potential and actual effects for farmers (Mbogoh et al, 2003;Muyanga, 2009;Njuguna et al, 2010), a rigorous assessment of broader welfare impacts has not yet been carried out. Our analysis builds on a survey of banana-growing households in Kenya, including adopters and nonadopters of TC technology.…”

“…To augment dissemination activities, selected early adopters were facilitated to establish demonstration plots and act as product champions within their farmer group and beyond. Considering Kenya as a whole, only around 6% of all banana farmers have adopted TC so far, although in Central and Eastern Provinces, where most of the dissemination programs started, adoption rates are already higher (Njuguna et al, 2010).…”

Classical innovation adoption models implicitly assume homogenous information flow across farmers, which is often not realistic. As a result, selection bias in adoption parameters may occur. We focus on tissue culture (TC) banana technology that was introduced in Kenya more than 10 years ago. Up till now, adoption rates have remained relatively low. We employ the average treatment effects approach to account for selection bias and extend it by explicitly differentiating between awareness exposure (having heard of a technology) and knowledge exposure (understanding the attributes of a technology). Using a sample of Kenyan banana farmers, we find that estimated adoption parameters differ little when comparing the classical adoption model with one that corrects for heterogeneous awareness exposure. However, parameters differ considerably when accounting for heterogeneous knowledge exposure. This is plausible: while many farmers have heard about TC technology, its successful use requires notable changes in cultivation practices, and proper understanding is not yet very widespread. These results are also important for other technologies that are knowledge-intensive and require considerable adjustments in traditional practices.JEL classification: C8, D8, O3, Q12, Q16, Q18

“…Foc was most frequent in soils from central Kenya (Humic Nitisol) and least isolated from Coast (Rhodic Ferralsol) and Nyanza (Vertisol). This could be attributed to the intensity of cultivation of bananas which is highest in central Kenya, where it is driven by market demands from the capital city of Nairobi, compared to the other two regions (Kung'u et al, 1998;Njuguna et al, 2010). Similarly, the frequency of F. proliferatum followed trends explained by the most prevalent host, maize which is cultivated in all the three regions but at different intensities.…”

The impact of microbiological commercial products (PHC Biopak, Rhizatech and ECO-T) on the occurrence of mycorrhizae and Fusarium in the rhizosphere of tissue culture banana (Gros Mitchel cv.) was assessed. Tissue cultured banana plantlets were inoculated with PHC Biopak (Bacillus), Rhizatech (mycorrhiza) and ECO-T (T. harzianum) under greenhouse conditions using a completely randomized design in a Vertisol, Rhodic Ferralsol and Humic Nitisol sampled from the major banana growing regions in Kenya. Potted plants were later established under field conditions in the three agro ecological zones. Roots and soils sampled at end of potting and at flowering were assessed for AM fungi colonization and Fusarium populations. The effect of product inoculation on AM fungi colonization varied and only significant (p<0.05) in Rhodic Ferralsol with Rhizatech increasing intensity of colonization by 31.9% and PHC Biopak increasing the frequency of colonization by 38.6% compared to the non-inoculated control (12.9%). F. oxysporum, fsp. cubense, F. proliferatum and F. incarnatum were recovered from the experimental soils. Foc was the most abundant in the three soils (prior to inoculation) accounting for 60.6% of all Fusarium colony forming units. After inoculation, at the end of potting stage and at flowering, F. proliferatum was mostly isolated from the three zones accounting for 35.2% of the total fungal population. Foc was isolated from Humic Nitisol and Vertisol accounting for 11.5% of the total fungal population. PHC Biopak, ECO-T and Rhizatech suppressed Foc colony forming units per gram of soil by 47, 68 and 55%, respectively in the Humic Nitisol. ECO-T reduced Fusarium colony forming units per gram of soil by 6% in Rhodic Ferralsol and PHC Biopak by 50% in Vertisol compared to the non-inoculated soils. There is potential in use of commercial microbiological products to suppress Foc and the efficacy of the products depends on soil physico-chemical properties.
