- Description: Root crops, such as sweet potatoes, are important sources of carbohydrates in the pacific region where soils are generally of inferior quality. Sweet potato leaves are said to be more nutritious when compared with storage roots, therefore can be used as a source of nutrition by human beings. Sweet potatoes like other vegetables are perishable and therefore they need to be processed in order to increase storage life. The shelf life of perishable vegetables can be increased by the use of drying methods. This brings an opportunity area for research to realize the full potential of sweet potatoes. Sweet potatoes can be developed as a sustainable crop for diverse nutritionally enhanced and value-added food products to promote human nutrition. Thus, the study sought to develop nitrogen level that could result in maximum yield of tubers while the green leaves are harvested for human consumption. The study also sought to find the best suitable drying method to extend the shelf life of orange-fleshed sweet potatoes OFSP leaves. The research was conducted at the University of Fort Hare glasshouse, Alice, in the Eastern Cape Province of South Africa. OFSP plants were grown at the UFH research farm, harvested and sorted according to their different age groups. The leaves were then taken to the glasshouse for the experiment to be conducted. The first experiment followed CRD 4x3 factorial replicated 3 times, with 4 levels of leaf age (upper, middle, lower, basal) and 3 levels of drying sun, shade, oven. The second experiment followed a RCBD replicated five times, with 4 levels of N 50 100 150, and 200 kgha randomly allocated. All the nutritional analysis was done based on the recommendations by the Association of Official Chemists A.O.A.C. Statistical analysis was done using SAS, Version 9.1. Where a significant difference was detected, variable means were separated using Fisher’s protected least significant difference p 0.05. , Thesis (MSc) -- Faculty of Science and Agriculture, 2023

- Description: Recently, gender-based violence (GBV) cases in South Africa have increased, despite all the effort that the government had invested in trying to curb GBV. This study explores staff knowledge, perceptions of GBV related to support services and intervention strategies at the University of Fort Hare, East London Campus. To get indepth information from the research participants, this study utilised qualitative research and semi-structured interviews for data collection. Interviews were conducted with ten staff members, eight of whom were females and two of whom were males. This study used convenience and snowball sampling to select the interviewed staff members. This study concludes that most of the research participants were not aware of the support services and intervention strategies that are available to fight gender-based violence at the University of Fort Hare, East London campus. The participants were also not aware of the procedure that needs to be followed when gender-based violence occurs. This study’s findings point to the need for the University of Fort Hare to continue providing educational awareness campaigns for both staff and students and to enlighten the University community about procedures that need to be followed when incidents of gender-based violence take place. In addition, the findings suggest that the research participants' understanding of GBV is, to some extent, influenced by a radical feminist perspective, while the solutions are influenced by a liberal feminist perspective. The research raises the question as to how GBV may be addressed when solutions do not seemingly speak to the cause. , Thesis (MSoc Sci) -- Faculty of Social Sciences and Humanities, 2025
