The marketability of small scale hydroponic systems for the horticultural industry in South Africa
(Cape Peninsula University of Technology, 2016)Hydroponics, i.e. plant cultivation in mineral-rich water is a synergy between plant, human, and machine. For decades the hydroponic garden has been offered on horticultural markets, and was repeatedly innovated to better ... -
A comparative study of oxygenation techniques in the hydroponic cultivation of Pelargonium Tomentosum
(Cape Peninsula University of Technology, 2016)This aim of this study was to investigate the viability of growing P. tomentosum in deep water culture (DWC) hydroponics and to assess the effects of various methods of oxygenating the nutrient solution with regards to ... -
Hydroponic propagation of Siphonochilus aethiopicus: an endangered medicinal plant
(Cape Peninsula University of Technology, 2017)The increasing demand for medicinal plants has led into serious over-harvesting of wild populations and presents an opportunity for potential profitable cultivation. Production of medicinal plants in controlled environments ... -
Monitoring extracellular enzyme activities and microbial population numbers during composting of winery solid waste
(Cape Peninsula University of Technology, 2016)Waste management in winery and distillery industries faces numerous disposal challenges as large volumes of both liquid and solid waste by-products are generated yearly during cellar practices. Composting has been suggested ... -
In vitro conservation of selected endangered plant species indigenous to the Cape Floristic Region, South Africa
(Cape Peninsula University of Technology, 2016)This study focused on optimising four types of in-vitro conservation methods, namely: 1), micropropagation, 2) in-vitro slow growth, 3) seed germination and 4) cryopreservation for selected endangered plant species indigenous ... -
Metal bioaccumulation, membrane integrity and chlorophyll content in the aquatic macrophyte ceratophyllum demersum from the Diep River, Western Cape
(Cape Peninsula University of Technology, 2012)The Diep River is approximately 80 km in length and runs through agricultural land and urban parts of greater Cape Town, South Africa before entering the Atlantic Ocean, via an estuary. Generally, metal pollution in South ... -
The effects of various drip fertigated water quantities on hydroponically cultivated Cucumis sativa L.
