Combining ability analysis for resistance to turcicum leaf blight in maize under highland agro-ecologies of Uganda
(Makerere University, 2022-08)Maize productivity in the highland areas of Uganda is constrained by high prevalence of pests and diseases, and low levels of input use. Turcicum leaf blight (TLB) (caused by Exserohilum turcicum) is one of the most important ... -
Effectiveness of forage and food legumes on management of the fall armyworm and crop performance in Uganda
(Makerere University, 2023-08)Maize production in Uganda is constrained by field insect pests, and declining soil fertility. The outbreak of fall armyworm (FAW) in 2016 increased production problems. Increased use of synthetic pesticides and large crop ... -
Identification of sources of resistance and inheritance to Fusarium wilt (Fusarium oxysporum f.sp. sesami) resistance in sesame
(Makerere University, 2021-02)Fusarium wilt (Fusarium oxysporum f.sp sesame) is one of the most destructive soil borne diseases in sesame in Uganda. Breeding for resistance and use of resistant varieties is the most economic and environmentally friendly ... -
Field evaluation and genomic regions discovery conferring resistance to Cowpea Scab (Sphaceloma sp.) in Uganda
(Makerere University, 2020)Cowpea (Vigna unguiculata L. Walp) is a vital leguminous crop consumed in most parts of Sub-Saharan Africa. Productivity of the crop in Uganda is limited by multiple constraints, cowpea scab caused by Sphaceloma Sp. being ... -
Farmers’ choices of shade trees for enhanced soil fertility in the Bugisu Coffee Agroforestry System, Uganda
(Makerere University, 2023-08)Coffee agroforestry is the intentional integration of trees in coffee for environmental, economic, and social benefits by farmers. It constitutes one of the range of choices that coffee farmers make as informed by their ... -
Effect of Cassava genotype and environment on population change and fitness of the Whitefly, Bemisia Tabaci (Hemiptera: Aleyrodidae)
(Makerere University, 2023)The whitefly pest complex Bemisia tabaci (Gennadius, 1889) is one of the most devastating agricultural pests globally. Over the past two decades, increased abundance of B. tabaci populations throughout the cassava‐growing ... -
Mapping Quantitative Trait Loci (QTL) for Resistance to Bruchids (Callosobruchus maculatus) in Cowpea
(Makerere University, 2023-07-20)In storage, cowpea (Vigna unguiculata) experiences significant damage from biotic agents especially cowpea bruchids (Callosobruchus maculatus). This results in cowpea grain deterioration making the seeds unfit for human ... -
Effect of gender and extension on cassava profitability among smallholder farmers in Uganda
(Makerere University, 2023-05)The study assessed the effect of gender and extension on cassava profitability among farmers in Uganda. Understanding profitability by policymakers builds a trajectory toward policy discourse and evaluation. The Uganda ... -
Genotype-by-environment interaction of yam (Dioscorea species) for yam mosaic virus resistance, dry matter content and yield in Uganda
(MDPI, 2022-08-23)Often, yam cultivars grown in different agro-ecologies show differential responses across production environments, a term known as "genotype-by-environment interaction. Such genotype-by-environment interaction makes the ... -
Phenotypic diversity within Ugandan yam (Dioscorea species) germplasm collection
(Hindawi, 2022-12-19)A proper understanding of the diversity of the available germplasm is an initial step for the genetic improvement of a crop through breeding. However, there is limited information on the diversity of Uganda’s yam germplasm. ... -
Genetic diversity and population structure of Uganda’s yam (Dioscorea spp.) genetic resource based on DArTseq
(Public Library of Science, 2023-02-14)Assessing the genetic diversity of yam germplasm from different geographical origins for cultivation and breeding purposes is an essential step for crop genetic resource conservation and genetic improvement, especially ... -
Diversity and genome-wide association mapping of farmer preferred traits yam genetic resources in Uganda
(Makerere University, 2023-04-03)Although yam is a very important crop with the potential to address future food insecurity resulting from challenges due to climate change and increasing world population, its potential has largely remained unexploited in ... -
Household vulnerability to flood hazards in Kalehe Territory, Eastern D.R Congo
(Makerere University, 2023-01-12)Floods hazards are common and prevalent in Kalehe Territory, Eastern DRC, and often causing damage to the community. However, despite the prevalence of flood hazards, there is a paucity of information and knowledge on the ... -
Climate variability extremes, pastoralists adaptation strategies and future livestock productivity in the rangelands of Uganda
(Makerere University, 2022-09)A study was conducted to determine trends of variability and extremes of rainfall and temperature; pastoralists’ perceptions to the changes in rainfall and temperature extremes and predict future livestock productivity in ... -
Diversity and heritability of tomato resistance to Ralstonia solanacearum
(Makerere University, 2022-12-22)Bacterial wilt (BW) incited by Ralstonia solanacearum, known to attack over 450 plant species in the tropics and subtropics, is a devastating disease limiting tomato production in Uganda and worldwide. This study aimed to ... -
Economic feasibility of ware potato storage technologies in Eastern and Southwestern Districts of Uganda
(Makerere University, 2023-01)Seasonal fluctuation in food supply is a key cause of price instability, especially where post-harvest handling of agricultural produce is poor. Practices which extend the shelf life of crops and reduce incidences of ... -
Analysis of genetic diversity and progress made in bean breeding in Uganda
(Makerere University, 2023-01)Over the past 56 years, many cultivars of common beans have been released in Uganda but the genetic gain made in grain yield and related traits have never been documented. The morphological and genetic diversity of these ... -
