Potato viruses in Uganda and prevalence of extant R genes that suppress the effects of virus diseases
(Arinaitwe, A. B. (2022). Potato viruses in Uganda and prevalence of extant R genes the suppress the effects of virus diseases. (Unpublished PhD Dissertation). Makerere University, Kampala, Uganda., 2022-06-28)Viral diseases are one of the factors limiting potato productivity and accounts for 10-100% of the yield losses in Uganda. Infections by Potato virus Y (PVY) and or Potato leafroll virus (PLRV) are very important in inducing ... -
Genetic progress of yield and its components of Uganda sorghum varieties through breeding
(Makerere University, 2022-06)Genetic progress and diversity of released sorghum varieties over the last 50 years in Uganda have not been assessed. This has led to limited information on the diversity, rate of genetic progress for grain yield and its ... -
Consumer acceptance and willingness to pay for shelf life extended fresh cassava roots in Uganda: the case of Kampala District
(Makerere University, 2022-03-16)High post-harvest losses along the fresh cassava roots value chain increase food insecurity as a result of reduction in the amount and quality of food available for consumption. New modern technologies such as; waxing have ... -
Factors influencing reversion from virus infection in sweetpotato
(John Wiley & Sons, Inc, 2019-11-06)Viruses limit sweetpotato (Ipomoea batatas) production worldwide. Many sweetpotato landraces in East Africa are, however, largely virus-free. Moreover, some plants infected by the prevalent Sweet potato feathery mottle ... -
Characterising reversion from virus infection in sweetpotato
(Makerere University, 2022-06-14)Sweetpotato (Ipomoea batatas) production is negatively impacted by viral infections. However, some East African sweetpotato cultivars were recently reported to “fight off” viral infection through reversion process. Very ... -
Effect of Silicon and Potassium on growth and yield of East African Highland Banana
(Makerere University, 2022)Soil fertility is a major constraint to East African highland banana (hereafter referred to as highland banana) and a key concern for ongoing research efforts. Among primary nutrients, potassium (K) is by far the most ... -
Farmers’ willingness to participate in alternative delivery channels of improved bean seed
(Makerere University, 2018-04)The conventional seed delivery channels have mainly delivered improved seed of hybrid varieties and vegetables and little of the open-pollinated varieties such as common bean (Phaseolus vulgaris). The pan-African bean ... -
The influence of partnerships in enhancing functionality of one stop center association –(OSCA) rice value chains in Uganda
(Makerere University, 2022-06-02)Government and Non-Government organizations in Uganda promote partnerships in farmer organizations as a strategy for improving value chain functionality. The right partnerships connect small holder farmers to agricultural ... -
Enhancing acceptance of video content through farmers' participation in production of farmer-learning videos in Central Uganda
(Makerere University, 2022)The use of videos in agricultural extension is advanced as a means of improving farmers’ access to agricultural information. Several studies have assessed use of videos in extension with little regard to the appropriateness ... -
Soil carbon dioxide emissions in a cereal cropping system under nitrogen application in an inland valley wetland in Uganda
(Makerere University, 2021-11)Utilization of inland valley wetlands for agriculture is on the increase, in effect threatening the values associated with an intact wetland ecology. Moreover, it has become inevitable that some form of agriculture must ... -
Sorghum (Sorghum bicolor) as a bean intercrop or rotation crop contributes to the survival of bean root rot pathogens and perpetuation of bean root rots
(Wiley, 2017-03-04)Root rots (RR) are the main cause of declining bean (Phaseolus vulgaris) production in southwestern Uganda. Here, beans are mainly intercropped/rotated with maize (Zea mays), sorghum (Sorghum bicolor), sweet potato (Ipomoea ... -
Management of bean root rots in the bean based cropping system in Southwestern Uganda
(Makerere University, 2014-06-02)Root rots are the main cause of declining bean (Phaseolus vulgaris L.) production in southwestern Uganda. In this region, beans are often grown in association with other crops, i.e., maize, sorghum, peas, solanum potatoes, ... -
Evaluation of groundnut (Arachis hypogaea L.) lines for adaptability and reaction to rust disease
(Makerere University, 2022-05)Groundnut (Arachis hypogaea L.) is an important food crop in Uganda because of its high protein and oil content. Although a wide phenotypic diversity has been observed within cultivated groundnut, the genetic diversity ... -
Exploring niches for enhanced soyabean productivity in smallholder farms of Northern and Eastern Uganda
(Makerere University, 2022-05-11)Most agricultural soils in Sub-Saharan Africa are highly heterogeneous and deficient in phosphorus (P), an important nutrient limiting productivity of soyabean. Heterogeneity in soil fertility is an opportunity for guiding ... -
Effects of climate variability on rainfed rice production: a case study of Northern farming system agroecological zone of Uganda
(Makerere University, 2022-05)Rice (Oryza sativa) production is growing rapidly not only as a major source of food and nutrition to the global populace but also as a strategic crop for poverty reduction among subsistence farmers in Uganda. Despite ... -
Genetic analysis of resistance to witchweed (Striga hermonthica) and tolerance to low soil nitrogen in selected tropical maize lines
(Makerere University, 2021)Striga (Striga hermonthica) and low nitrogen are major yield reducing factors in maize production in Uganda. Four Striga resistant inbred lines, four low nitrogen stress tolerant inbred lines and two inbred line testers ... -
