  1. Determining the effect of tree size, bark-wood bond strength and tree form on the productivity of an excavator-based harvester in <em>Acacia mearnsii</em> in the KwaZulu-Natal forestry region of South Africa

    Determining the effect of tree size, bark-wood bond strength and tree form on the productivity of an excavator-based harvester in <em>Acacia mearnsii</em> in the KwaZulu-Natal forestry region of South Africa

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The aim of this study was to determine the effect of tree size, bark-wood bond strength and tree form on the productivity of cut-to-length harvesting of Acacia mearnsii, using an excavator-based harvester with a SP Maskiner harvester head in the...
  2. Bark thickness and bark volume of <em>Pinus patula</em> in South Africa

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    In South Africa, tree volume tables and volume functions are usually based on the under bark stem volume. Many forest management studies, however, give the estimated over bark volume, in which case equations are required that estimate bark volume and...
  3. 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...
  4. Seasonal Fluctuations and Diversity of Bark and Wood-boring Beetles in Lowland Forest: Implications for management Practices

    Item type: Journal Article • Journal: South African Forestry Journal
    The phenology and diversity of wood-living beetles attacking Cedrela mexicana, Khaya nyasica and Milicia excelsa were observed for one year with weekly window-flight-trap collections. A total of 150 species (10 known to be common pests of timber) were collected, most...
  5. Quantitative description of woody plant communities: Part I. An approach

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Various descriptive units for woody plant communities are proposed. These are the Evapotranspiration Tree Equivalent (ETTE), Browse Tree Equivalent (BTE) and Canopied Subhabitat Index (CSI), which describe the status of a woody community in terms of potential moisture use, value...
  6. Quantitative description of woody plant communities: Part II. Computerized calculation procedures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Calculation procedures for various quantitative descriptive unit‐values are described. These procedures are divided into primary and secondary calculations. The former is then divided into the calculation of spatial tree volume and preliminary calculations regarding the complete quantitative description. The latter...
  7. Use of the SDSS test to predict the protein content and bread volume of wheat cultivars

    Use of the SDSS test to predict the protein content and bread volume of wheat cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The relationship between the sodium dodecyl sulphate sedimentation volume (SDSS test) and the protein content and bread volume of wheat cultivars was determined to ascertain whether the SDSS test could be used to predict these parameters of baking quality. This...
  8. Pine litter as substrate for propagation of vegetable transplants in trays

    Pine litter as substrate for propagation of vegetable transplants in trays

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The study evaluates the potential of pine litter for use as a substrate in the propagation of vegetable transplants in trays. Sub-optimum pH and electrical conductivity of pine litter were addressed by incorporating 10% feedlot manure by volume. The water...
  9. Progress and problems in rooting clonal <em>Carica papaya</em> cuttings

    Progress and problems in rooting clonal <em>Carica papaya</em> cuttings

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Carica papaya (L) is one of the few fruit crops that is still propagated commercially by seed. In the cool subtropical Pietermaritzburg area, a female clone ‘Honey Gold’ has been vegetatively propagated, by rooting leafy cuttings, for over 40 years...
  10. Effect of pine bark goat manure medium on seedling growth and N, P, K concentration of various vegetables

    Effect of pine bark goat manure medium on seedling growth and N, P, K concentration of various vegetables

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Pine bark compost is the medium of choice for seedling growers in South Africa due to its availability, low cost and good physical properties. However, it is acidic, has low electrical conductivity (EC) and nutrient content such that fortification and...
