Students need to develop cross-cultural awareness and understanding, which has led educational institutions to create high-impact global programs to enhance their academic learning. Global service-learning, a U.S.-based pedagogy, interconnects service-learning, study abroad, and international education programs. A service-learning program in [Country] was founded on the school garden approach which was conceptualized based on the emphasis by the Food and Agricultural Organization in 2004. NGO1, [State University], and [Country University] adopted school gardens as a feasible approach to fulfill the service-learning curricular objectives and meet NGO1’s goal of solving undernutrition in schools using garden products in school lunches. This study sought to determine the influence of service-learning program activities on alumni’s academic development. Alumni (n = 274) from 2006-2019 completed a self-administered questionnaire through Qualtrics where 94.2% responded. A principal components analysis (PCA) was employed, aligning activities into three components. The first component loaded school gardening, bi-national team projects, arrival orientations, farmer field visits, and school teaching assistance, depicting alumni’s community engagement in reciprocal learning. Component two loaded journaling/logbooks, critical reflections, and presentations, depicting alumni’s reflexive actions resulting in cognitive development through documenting and confronting their assumptions about their service-learning activities. Component three loaded co-curricular, tours and travels, and social parties, portraying alumni’s social life that provided opportunities to learn about distinct cultures. Pre-departure orientations loaded well on [State University] alumni’s PCA which mitigated culture shocks while in [Country]. Alumni could benefit overall from more instructor-led cognitive development activities whereby they could both learn from and question their activities.

Tomato cultivars (Heinz 1370, MT 56, and Nuru F1), fungicide application (±), staking (±), and mulching (±) were tested for their effect on yield, disease severity, and gross margin in tomato production in the Kamuli District of Uganda. Treatments were arranged in a randomized complete block design with a factorial and split-plot arrangement in field plots in two growing seasons during 2013. Total and marketable fruit number, marketable fruit weight, gross margin, and disease severity, assessed using the area under disease progress curve, were measured. Disease-resistant and open-pollinated ‘MT 56’ in combination with fungicide application and soil mulch provided the highest marketable fruit number and marketable fruit weight and had a positive gross margin in the first growing season. A combination of ‘MT 56’ and treatments without applying fungicide and soil mulch resulted in the only positive gross margin in season two. Application of fungicides reduced disease severity (early blight, Alternaria solani Sorauer) for all cultivars in season one and for ‘Heinz 1370’ and ‘Nuru F1’ in season two, but did not affect disease severity for ‘MT 56’ in the second season. Using soil mulch reduced the severity of early blight disease, but decreased the gross margin when purchased. Staking did not affect yield, disease severity of plants, and decreased the gross margin. Cultivar MT 56 had the highest gross margin and marketable fruit and least disease severity, and seeds should be made available to small-landholder tomato farmers in Uganda to enhance their sustainable livelihoods.

Tomatoes increase nutritional food security and income among Ugandan smallholder farmers who have limited access to high quality seed. The objective of this study was to analyze the current tomato seed value chain for Uganda. Survey responses determined roles of key participants, including Ministry of Agriculture, Animal Industry and Fisheries (MAAIF) for regulation and certification; National Agricultural Research Organization for breeding cultivars and seed multiplication; Makerere University for education and research; commercial seed companies for seed importation and conditioning; seed distributors for sales; and smallholder farmers as savers and end users of seed. Challenges included an inefficient domestic seed distribution system, technical constraints in seed production and conditioning by seed companies, inadequate networks and communication among the seed industry’s key participants, and partial regulation of the seed industry. Seed companies played a key role in seed conditioning processes. Companies imported all tomato seeds into Uganda and stated germination as their primary goal for quality. Challenges for seed companies included assistance from MAAIF to regulate and certify seed and access to improved technologies. Attaining high quality seed by commercial Uganda-parent companies will require additional investment and training of seed technologists for domestic testing and seed quality assurance.

Global service-learning fosters intercultural competence development. This study was grounded in the intergroup contact theory, which explains the causes of bias against one another and how intergroup contact helps negate those perceptions. We employed a comparative census between alumni of Iowa State University (ISU) and Makerere University (MAK) who participated in the summer school garden service-learning program, 2006–2019 through the Center for Sustainable Rural Livelihoods in Uganda. The study examined how alumni’s intercultural aspects changed as measured by self-perceived appreciation of differences (SAD) and awareness of structural inequalities (ASI). A self-administered questionnaire was sent to 274 alumni through Qualtrics where 94.2% responded. We found that ISU alumni had greater changes in their knowledge, attitudes, and awareness about intercultural aspects than MAK alumni. The diversity constructs of race, ethnicity, and gender accounted for differences whereby white and female ISU alumni had greater changes in their intercultural competence than alumni of color and males respectively. Also, binational housing influenced the differences, implying that service-learning programs should promote cross-cultural binational living arrangements for students. Intergroup contact through SAD can reduce cultural distance and ASI can foster alumni philanthropy, contributing to solving complex community problems such as undernutrition and illiteracy through school gardens. Global service-learning programs require faculty familiar with challenges in international education and culture of communities with which students conduct their service-learning. Faculty should facilitate pre-departure orientations to minimize students’ cultural shock during immersion in new communities and should also assist in post-service-learning program reflections to minimize reverse culture shocks.

Yield of strawberry grown continuously on the same site often declines over time as a result of proliferation of weed seeds and pathogenic organisms in the soil. Plots were established and maintained in seven different cover crops and as continuous strawberry or continuous tillage for 10 years (1996 to 2005) in a site that was previously in strawberry production for 10 years (1986 to 1995). Cover crops included blackeyed Susan ( Rudbeckia hirta L.), sorghum Sudangrass [ Sorghum bicolor (L.) Moench], marigold ( Tagetes erecta L.), big bluestem ( Andropogon gerardii Vitman), perennial ryegrass ( Lolium perenne L.), switchgrass ( Panicum virgatum L.), and Indiangrass [ Sorghastrum nutans (L.) Nash]. Treatments were ended in 2005 and plots were planted with ‘Honeoye’ strawberry in a matted row. Effectiveness of soil pretreatments in reducing weed populations and enhancing strawberry production was evaluated for four growing seasons by quantifying weed growth by type and biomass and strawberry plant density and yield. The results indicate that matted-row strawberry production plots that were either in continuous tillage or established in S. bicolor , P. virgatum , or A. gerardii before planting strawberry had lower weed biomass and greater strawberry plant establishment and yield than plots established in L. perenne or R. hirta or that had supported continuous strawberry production.
