Five tropically adapted buck breeds extensively managed in Ethiopia were studied to determine possible effects of breed and age on body size and testicular traits. In all, 177 bucks were selected following stratified random sampling, and evaluated in three age groups: <14 months (young), 14-19.5 ...

Body size and testicular traits of tropically-adapted bucks raised under extensive husbandry in Ethiopia
Host location, acceptance and larval success were studied in a mixed cultivar trial consisting of three East African cooking bananas, two East African beer banana and Kayinja (an exotic cultivar used for beer making). Weevil damage to the endemic cultivars was 5 to 25 times higher than that of Ka...

Between 1970 and 1990, highland green cooking banana production rapidly declined in the traditional growing areas in the central region, while during the same period banana production expanded in the country's southwest. Thus, Kampala's growing urban market for banana became dependent upon new gr...

The banana bacterial wilt caused by the Xanthomonas campestris pv. musacearum (Xcm) is one of the major constraints to banana production in Uganda. Field observations suggest that the primary means of disease spread is by insect transmission through the male flowers. This study carried out an inv...
