Trade-offs in adoption of Poultry Technologies: A case of peri-urban Kampala district
(Makerere University, 2022-11-30)Poultry production has increased in Uganda over the years in response to the global demand for animal protein. However, the failure rate of poultry enterprises in central Uganda is high, attributed to high costs of production. ... -
Response of potato ( Solanum tuberosum L.) to manipulation of row spacing, fertilizer use, and intercropping with beans
(Makerere University, 2022-12)South western Uganda is the leading potato producer contributing 60% of Uganda’s national potato production.The rapid population growth from 39 million in 2018 to 44million to date (2022)has greatly contributed to land ... -
Resistance to Cercospora Leaf spot disease and combining ability of selected Sesame (Sesamum indicum L.) lines in Uganda
(Makerere University, 2022-12-01)Cercospora leaf spot disease is one of the major diseases affecting sesame production in Uganda causing yield losses of between 22-53%. This study was conducted to evaluate response of selected sesame genotypes to Cercospora ... -
Effect of seed sources, seed tuber size and seed dressing on the performance of potato and late blight incidence in Uganda
(Makerere University, 2022)Uganda has a high potential for potato production. However, very low yields are still obtained. This is primarily due to the quality of the potato seed used. The capacity of certified seed production is too low to satisfy ... -
Performance and stability of a bi-parental sweet potato population for storage root yield, dry matter, starch and sugar content
(Makerere University, 2019-11-15)Sweetpotato production and utilization has taken a new trend, as farmers look more into value addition for an increased income. This means that root quality traits such as starch and sugar content that received less attention ... -
Market participation and profitability of maize production by smallholder farmers in Masindi and Hoima Districts of Uganda
(Makerere University, 2022)Maize production is a strategic enterprise in Uganda because of its increasing contribution to household incomes, foreign exchange and food security. The crop is increasingly becoming a staple food for many people especially ... -
Performance and genomic prediction of Cassava brown streak disease response in selected Nigerian cassava germplasm
(Makerere University, 2022)Cassava mosaic geminiviruses (CMG) and Cassava brown streak virus (CBSV) cause the highest yield losses in Africa's cassava production. Cassava brown streak disease (CBSD) in particular has been and continues to be a ... -
Mechanisms of adaptation of low soil phosphorus tolerant common beans to water deficit
(Makerere University, Kampala, 2022-11-01)ABSTRACT Water deficit due to unreliable rainwater supply and soil phosphorus deficiency are by far the most prevalent abiotic stresses limiting common bean production in sub-Saharan Africa. Intervention into these ... -
Impact of oil and gas waste disposal on water and soil quality: A pilot study of Ngara & Bugungu waste consolidation sites in Buliisa District, Uganda
(Makerere University, 2022-09)Oil wastes from the exploration operations in the form of drilling muds, cuttings and chemicals contaminate the environment and threaten human health and ecosystems. The aim of this study was to assess the impacts of oil ... -
Stability and genetic diversity of cowpea elite lines in Uganda
(Makerere University, 2022-10)Cowpea yields in farmers’ fields continue to be low because of multiple stresses exacerbated by adverse effects of climate change. Therefore, there is a need to develop new cowpea varieties that have combined resilience ... -
Assessment of purity of yellow common bean seeds in Tanzanian markets
(Makerere University, 2022)In Eastern Africa, common beans are a major source of food and revenue for smallholder farmers who make up the bulk of the population. However, yellow bean trade is affected by limited information and unstructured system ... -
Gender and climate change adaptation among bean growing households in Northern and Eastern Uganda
(Makerere University, 2022-06)Beans are an important legume in Uganda although less adapted to extreme environmental conditions. Adapting the bean crop to the changing climate is one of the best ways to improve bean productivity and smallholder farmers’ ... -
Transaction costs and governance of value chains of organic pineapples from Uganda
(Makerere University, 2022-08)The organic sector is one of the fastest growing sectors globally. It provides an opportunity for developing countries to export high value products in the global market. One such opportunity for Uganda is the export of ... -
Potential influence of gender on farmer willingness to pay for grafting technology for sustainable control of tomato bacterial wilt disease in selected districts of Uganda
(Makerere University, 2022-08-09)Tomato plays a great role in income generation for many small holder farmers in Uganda, but it is hampered by Bacterial Wilt Disease (BWD). Because BWD is soil-borne, adoption of grafted seedlings that are resistant to BWD ... -
Role of silicon in mediating resistance towards rice blast in selected rice varieties
(Makerere University, 2022-07)Rice blast caused by Magnaporthe grisea is one of the most serious diseases of rice, causing yield losses of 50 – 100% in susceptible varieties worldwide. Durable host resistance has been hard to achieve given large pathogen ... -
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 ... -
