Genetic enhancement of sorghum for yield-related traits and drought tolerance through induced mutagenes.
Sorghum (Sorghum bicolor [L.] Moench) is the foundation crop in the world's dry regions, for food, feed, and bioenergy feedstock. There has not been a systematic breeding program and farmers-preferred varieties of the ... -
Crop suitability mapping for underutilized crops in South Africa.
(2022)Several neglected and underutilised species (NUS) provide solutions to climate change and create a Zero Hunger world, the Sustainable Development Goal 2. However, limited information describing their agronomy, water use, ... -
Dormancy breaking methods and priming techniques to improve seed germination in gynandropsis gynandra (L.) briq syn cleome gynandra L. (Cleomaceae).
(2022)Gynandropsis gynandra, commonly known as spider plant, is a leafy vegetable that belongs to the Cleomaeae family. Spider plant is used for its medicinal properties, but also as a nutritional supplement, and an animal ... -
Evaluating seed quality and performance of low and high phytic acid maize (Zea mays L.) under varying phosphorus rates and water regimes in dryland conditions.
Maize (Zea mays) being the staple crop for many communities in Sub-Saharan Africa and also used for animal feeding, a considerable effort has been made to improve quality and yield. In recent times plant breeders have ... -
Assessing variability in yield performance and nutritional quality of citron watermelon (citrullus lanatus var. citroides (L.H. Bailey) mansf. ex greb.) genotypes under drought conditions.
Research is needed to investigate the potential of Neglected Underutilized Crop Species (NUCS) such as citron watermelon, to increase crop diversity and mitigate the effects of prolonged drought because of climate change. ... -
Integrated weed management using intercropping and weeding frequency for sorghum, dry bean and cowpea.
(2021)Weed management is a complex topic in agriculture. This is despite the fact that it may be one of the oldest crop management techniques to improve yield. Currently, agriculture predominantly uses chemical weed control ... -
Response of primed soybean (Glycine max L.) to storage duration and ambient conditions.
(2022)Abstract available in PDF. -
Assessing the fertiliser value of co-composted biochar compost made from black soldier fly larvae faecal residue.
(2021)The Black Soldier Fly Larvae (BSFL) technology can treat faecal sludge emptied from full Urine Diverting Dry Toilets (UDDT’s). A residue containing residual mineral elements such as nitrogen (N), phosphorus (P), potassium ... -
Role of fertilisation regimes on the yield and nutritional benefiits of cowpeaamaranth intercropping systems.
(2020)Several African leafy vegetables (ALVs) contribute to food and nutritional security of rural communities, particularly due to their ability to grow in marginal soils. These ALVs such as amaranth and cowpea among others ... -
Assessing the potential use of struvite and effluent from decentralized wastewater treatment systems (dewats) as plant nutrient sources for early maize ( zea mays) growth.
(2021)The Decentralised Wastewater Treatment System (DEWATS) effluent has been shown to contain considerable concentrations of mineral elements such as nitrogen (N) and phosphorus (P), which are important for plant growth. The ... -
Application and evaluation of aquacrop, dssat and simple model in modelling yield water use of selected underutilised cereal crops.
(2021)The study compared yield, biomass, and water use (WU) for maize, sorghum, and millet simulated using three crop models of varying complexity: AquaCrop, DSSAT and the SIMPLE model. The hypothesis was that there is no ... -
Assessing nutritional water productivity of selected African leafy vegetables using the agricultural production systems simulator model.
(2020)Food and nutrition insecurities are regarded as one of the main challenges in the Sub-Saharan region. While substantial progress has been made to address food and nutrition challenges, this progress has varied across the ... -
Physiological analysis of responses of lateral branching of the primary root for tolerance to phosphorus stress and drought in the common bean (Phaseolus vulgaris L.).
(2021)Common bean (Phaseolus vulgaris L.) is essential to the food security of millions of people in developing nations. However, inadequate precipitation and low soil fertility, mainly phosphorus (P) deficiency, tend to limit ... -
Vertical hydroponic production of leafy vegetables with human-excreta-derived-materials (HEDMs) from decentralised sanitation technologies.
(2020)Hydroponic production of leafy vegetables with human-excreta-derived-materials (HEDMs) extracted by decentralised sanitation technologies is projected to reduce food shortages while improving sanitation services in peri-urban ... -
Response of potato genotypes to production sites and water deficit imposed at different growth stages.
(2020)In South Africa, potato is an important food security crop widely cultivated by smallholder farmers due to its extensive adaptation characteristics. However, drought adaptive responses of potato genotypes vary under ... -
Water use and nutritional water productivity of taro (colocasia esculenta L. Schott ) Landraces.
(2020)Taro (Colocasia esculenta) is a vital drought tolerant crop with the ability to produce corms of high nutritional quality, but it still occupies low levels of utilisation and research in South Africa. Information on crop ... -
Timing of weed control and harvest date effects on potato crop field performance and mineral content.
(2020)Potato (Solanum tuberosum) is an important vegetable crop that is high on dietary minerals and vitamins that are needed by the human body but can be a weak competitor to weeds. The aim of the study was to determine the ... -
Artificial soil profile for vegetable production: a potential case of urban agriculture.
(2020)A significantly large population of South Africa migrates from rural to urban areas, leaving opportunities for small-scale subsistence agriculture for a perceived better livelihood. Food insecurity and poverty seem to ...
