  1. Extreme significant wave height climate in the Gulf of Guinea

    Extreme significant wave height climate in the Gulf of Guinea

    Item type: Journal Article • Journal: African Journal of Marine Science
    This article investigates spatio-temporal trends for different return periods of extreme significant wave height (SWH) in the Gulf of Guinea (GG), northeastern tropical Atlantic Ocean, based on a 37-year (1980–2016) wave hindcast. High-resolution reanalysis windfield datasets were used to force...
  2. Growth, Yield and Timber Density of Short Rotation Coppice Stands of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of timing initial coppice reductions, number of reductions and final number of shoots per stool on growth and yield of Eucalyptus grandis are described. The basic data were obtained from three experiments situated in different climatic zones of...
  3. Floristic and Structural Composition of Wonderwoud Forest in the Wolkberg, North-Eastern Transvaal

    Item type: Journal Article • Journal: South African Forestry Journal
    The closed, evergreen forest of 450 ha was studied by means of a survey of 55 circular plots of 0,04 ha, distributed in a grid pattern. TWINSPAN classification separated the forest into four stand types: Olea capensis macrocarpa—Xymalos monospora—Syzygium gerrardii...
  4. Floristic and Structural Composition of Hanglip Forest in the Soutpansberg, Northern Transvaal

    Item type: Journal Article • Journal: South African Forestry Journal
    The closed, evergreen forest of 363 ha was sampled by means of 62 circular plots of 0,04 ha, distributed in a grid pattern. TWINSPAN classification separated the forest into regrowth forest with two forest types, and mature forest with four...
  5. Modelling Diameter and Height Distributions through Dispersion Statistics in Even-aged Pine Plantations

    Item type: Journal Article • Journal: South African Forestry Journal
    Diameter and height distribution recovery, in combination with standlevel projection modelling, is generally used in Southern Africa for predicting growth and yield in even-aged pine plantations. A different approach for modelling diameter and height distributions for five pine species commercially...
  6. Characteristics of fire behaviour in the montane grasslands of natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Fire behaviour characteristics were investigated in the montane grasslands of the Natal Drakensberg. The behaviour of experimental fires was measured together with the accompanying biotic and abiotic conditions. Estimates of heat yield, mass of available fuel and forward rate of...
  7. Patterns of defoliation in four‐ and eight‐paddock grazing systems

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Patterns of defoliation of the dominant palatable species in a recommended eight‐paddock system and a four‐paddock system with the same grazing cycle were monitored by repeated observations of marked tillers. In the two systems, the percentages of palatable species grazed...
  8. Utilization of <em>Lolium multiflorum</em> by sheep 1. Influence of dry matter content and correlated factors on voluntary intake

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The intake by young sheep of Lolium multiflorum cv. Midmar (ryegrass) with dry matter (DM) contents of between 10.2% and 20.5% was studied. Intake was measured on pasture, while at the same time herbage was cut and fed either fresh...
  9. The effects of chlormequat chloride and ethephon on agronomic and quality characteristics of South African irrigated wheat

    The effects of chlormequat chloride and ethephon on agronomic and quality characteristics of South African irrigated wheat

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Plant growth regulators (PGR's) that reduce lodging have not been evaluated on commercial wheat cultivars under local irrigated conditions. The objective of this study was to assess the effects of PGR's on agronomic and quality parameters of three wheat cultivars...
  10. Use of ethephon and chlormequat chloride to manage plant height and lodging of irrigated barley (cv. Puma) when high rates of N-fertiliser are applied

    Use of ethephon and chlormequat chloride to manage plant height and lodging of irrigated barley (cv. Puma) when high rates of N-fertiliser are applied

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The objective of this study was to evaluate the effects of the plant growth regulators (PGR's) chlormequat, ethephon and their combination on plant height, lodging, grain yield and yield components of ‘Puma’ barley with differing amounts of N (120, 150...
