Abundance and diversity of tomato rhizosphere microbes in different land uses and their effect on bacterial wilt disease in Uganda
Nampamya, Doreen
Agricultural production is associated with changes in microbial diversity. This often leads to
microbial unevenness and multiplication of soil borne diseases such as wilts, which are tedious to
control and trend managed through use of biocontrols. Microbiome composition and land use
management have been mentioned as core factors in effectiveness of biocontrols. Therefore, this
study determined the diversity and abundance of microbes in the tomato rhizosphere and its effect
on severity and biocontrol of bacterial wilt disease in soils from different land uses . Tomatoes
were grown in a screen house at Namulonge using unsterilized soils from cultivated, fallow and
forest land use types and were inoculated with Ralstonia solanacearum (positive control) but also
include a non-inoculated set (negative control). Four biocontrols were used namely; Bacillus
subtilis, Bacillus amyloliquefaciens, Peanibacillus polymyxa and Stenotrophomonas rhizophila.
Data were collected on plant growth and yield parameters, and bacterial wilt disease incidence.
Rhizosphere microbiome data were obtained using amplicon sequencing. Results showed that B.
subtilis and P. polymyxa increased plant height in all land use types. Biocontrols B.
amyloliquefaciens and S.rhizophila resulted into the highest dry biomass in cultivated land use, B.
amyloliquefaciens and P. polymyxa in fallow and P. polymyxa and B. subtilis in forest land use
type. In cultivated land use, biocontrols B. amyloliquefaciens, B. subtilis and S. rhizophila reduced
bacterial wilt incidence by 31 % and P. polymyxa by 28 %. Fallow land use type had the highest
microbial diversity and forest land use had the highest microbial abundance. The major phyla were
Proteobacteria, Actinobacteria and Acidobacteria in Forest, Fallow and cultivated land uses
respectively. Bacillus and Paenibacillus bacteria were more abundant in cultivated while
Stenotrophomonas bacteria were more abundant in forest land use type

Acceptance and willingness to pay for potato-based cookies: a case of urban consumers in South-western Uganda.
Nantambi, Bridget
In Uganda, potato is mainly consumed in boiled form. However, there is a huge potential for
processing potato into high value products because of the growing population coupled with
changes in food eating habits and increased demand for snacks especially among urban
consumers. Such high-value potato products include chips, cookies, cakes, bread and waffles.
Using the newly developed potato-based cookies, the study sought to address the question
whether these products are accepted by consumers, and the price they are willing to pay for
them. The study further investigated factors likely to influence consumer willingness to pay for
the cookies. It was hypothesised that potential consumers are different in terms of cookie
buying frequency, and the income they earn has an influence on their willingness to pay for the
cookies. The study was conducted in South-western Uganda in Kabale, Kisoro, and Mbarara
urban areas where a random sample of 613 potential consumers was interviewed. Contingent
valuation method, descriptive analysis, Logit and Tobit econometric models were used to
analyze the market survey data. Results indicate a high level of consumer acceptance for the
potato-based cookies; about 91% accepting to buy the cookies. Taste was the most important
attribute consumers considered while purchasing cookies followed by the price. Consumer’s
age, income, per capita quantity and availability of related snacks significantly influenced the
frequency of cookie purchases. The minimum price consumers were willing to pay was about
603 Uganda Shillings (US$ 0.63) per 100gm pack. The willingness to pay was positively and
significantly (P≤0.05) influenced by income of a consumer and the proportion of their food
budget, but negatively influenced by being employed and the number of dependants in the
household. The processor should, therefore, produce differentiated products with assorted
attributes in order to cater for the various consumer segments. The cookies should be produced
using low-cost production and efficient technologies and marketed at a relatively competitive
price

Access and coverage: Which farmers do plant clinics reach in Uganda?
Karubanga, Gabriel; Matsiko, Frank B.; Danielsen, Solveig
This article reports on a study that assessed farmers’ access to, and coverage of, five plant clinics operating from market places in two districts of Uganda.
Despite the noticeable geographic and thematic coverage of the services, placing plant clinics at markets did not automatically ensure equitable access and high farmer attendance. Clinic users were predominantly middle-aged male farmers and overall attendance was relatively low.
Uganda has taken plant clinics to scale in recent years due to their potential to strengthen the country’s responsiveness to pests and diseases. Optimising farmer reach and ensuring equity in access requires reviewing clinic placement, timing, and mobilisation strategies.
