Screening groundnut (Arachis hypogaea L.) genotypes for tolerance to soil acidity.
(2011)Groundnuts (Arachis hypogaea L.) are an important subsistence and cash crop for smallholder farmers in Southern Africa. They require well drained light textured soils. However, most light textured soils are acidic and ... -
Screening of cover crops under conservation agriculture.
(2016)The practice of conventional tillage results in land degradation, reducing soil fertility due to soil erosion. Conservation agriculture aims at reducing soil disturbance which brings benefits of soil conservation. The call ... -
Screening sweetpotato (Ipomoea batatas L.) for drought tolerance and high β-carotene content in Mozambique.
(2011)Sweetpotato (Ipomoea batatas, L.) is one of the important sources of carbohydrates and economic income in Mozambique. As with most of the food crops in Mozambique, it is usually produced by small-scale farmers under ... -
Season effects on the potential biomass and sucrose accumulation of some commercial cultivars of sugarcane.
(2009)An experiment was conducted at Pongola (27°24´S, 31°25´E; 308m altitude) in South Africa to study the effects of season on growth and potential biomass and sucrose yields on nine commercial sugarcane cultivars. The treatments ... -
Seasonal variation of surface energy fluxes above a mixed species and spatially homogeneous grassland.
(2011)The increasing human population, industrialization, urbanisation and climate change challenges have resulted in an increased demand for already scarce water resources. This has left the agricultural sector with less water ... -
Sediment dynamics and provenance of hydrologic and vegetation signals of the Mzimvubu Catchment, Eastern Cape, South Africa.
(2020)Southern Africa has a high vulnerability to future climate change, therefore realiable and comprehensive information on local hydrological, vegetation and sediment processes are crucial for future ... -
Sedimentary models and geomorphological classification of river-mouths on a subtropical, wave-dominated coast, Natal, South Africa.
(1991)Abstract available in PDF. -
Sedimentary models for coal formation in the Klip River coalfield.
(1988)The primary objective of this study was to establish sedimentary models for peat formation in the southern part of the Klip River coalfield during Ecca (Permian) times and to assess palaeoenvironmental controls on coal ... -
Sedimentology, coral reef zonation, and late Pleistocene coastline models of the Sodwana Bay continental shelf, Northern Zululand
(1991)This geostrophic current-controlled Zululand/Natal shelf displays a unique assemblage of interesting physical, sedimentological and biological phenomena. The shelf in this area is extremely narrow compared to the global ... -
Sedimentology, stratigraphy and geological history of part of the northern KwaZulu-Natal coastal dune cordon, South Africa.
(1999)The northern KwaZulu-Natal coast is backed by a continuous aeolian dune cordon that rises in places, to a height of more than 100 metres and a width of 2 kilometres. This MSc thesis documents the geomorphology of the ... -
Seed quality and water use characteristics of a bambara groundnut (Vigna subterranea L.) landrace differing in seed coat colour.
(2014)Bambara groundnut (Vigna subterranea L.) is an underutilised African legume that fits the same ecological niche as Arachis hypogea (groundnuts). Because of its reported drought tolerance and high water use efficiency ... -
Seed quality and yield of selected traditional and commercial crops : vegetable water use and nutritional productivity perspectives.
(2017)Sub-Saharan Africa (SSA) faces challenges of achieving nutrient and food security under water limitations due to climate change and variability. Under these conditions, it is important to adopt cropping systems that are ... -
Seed-borne pathogens and the bean weevil (Acanthoscelides obtectus) in bean (Phaseolus vulgaris) seed and their effect on seed germination and vigour.
(2003)Two semi-selective media, MT and MSP, were compared for their ability to recover cells of the bacteria Xanthomonas axonopodis pv. phaseoli (Xap) and Pseudomonas syringae pv. phaseolicola (Psp), the causal organisms of ... -
Seeking a deeper understanding of the quality of relationships in the smallholder maize production system in Msinga.
(2011)In South Africa, the majority of inhabitants rely on agriculture as the main source of livelihood. Agricultural crop production remains the primary source of subsistence, employment, and income. Due to policies put in ... -
Segregation, desegregation, and re-segregation and the return to Black Townships : a case study of Chesterville Township, Durban.
(2014)Residential segregation and desegregation continues to be a major theme in South African scholarship. However the study of re-segregation, characterised by people returning to legacy apartheid townships after having moved ... -
Seismic stratigraphy of the northern KwaZulu-Natal upper continental margin.
(1998)This study presents the interpretation of Edo-Western and Sparker seismic geophysical data acquired on the northern KwaZulu-Natal upper continental margin by various organisations since 1981. Five seismic sequences are ... -
The seismic stratigraphy, geological evolution and CO2 storage potential of the offshore Durban Basin, South Africa.
(2017)Abstract available in PDF file. -
Seismic, geochemical and sedimentological characteristics of storm deposits from the Durban continental shelf, South Africa.
(2015)The Durban shelf is a wave-dominated, high energy setting, characterised by submerged shorelines at depths of ~60 m, backed to landward by low-relief backbarrier depressions. The exposure at the seafloor of a back-barrier/lagoon ... -
Seismic-stratigraphic models for late Pleistocene/Holocene incised valley systems on the Durban continental shelf.
(2013)This dissertation examines the Durban continental shelf of the east coast of South Africa from a seismic and sequence stratigraphic perspective. High resolution seismic data reveal eleven seismic Units (A-K) offshore ...
