  1. The Amelioration of <em>Pinus patula</em> Mortality on Former Agricultural Sites through Fertilisation: A Bioassay and Greenhouse Study

    Item type: Journal Article • Journal: South African Forestry Journal
    Recent expansion of the timber industry into areas previously used for agronomic production has, in many cases, resulted in poor growth of Pinus patula and P. elliottii seedlings and in certain instances complete stand failure. A bioassay study was initiated...
  2. Chemical Evaluation of Leaf Fibre Residues from Tropical Tree Legumes—a Wealth in Social Perspective

    Item type: Journal Article • Journal: South African Forestry Journal
    Leaf fibre residues obtained as a by-product during bulk extraction of leaf protein meal from three tropical forest trees viz. Albizzia procera Benth., Dalbergia sisso Roxb. and Delonix regia Raf. were analysed for their chemical and mineral composition. The fibres...
  3. Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Six levels of maize stover, expressed as percentage ground cover (0ā€“75%) were compared under a rainfall simulator to assess the effect of surface residues on infiltration and soil loss on a clay loam soil with a 3,5% slope. Increasing the...
  4. The effect of tillage: maize residue interactions upon soil water storage

    The effect of tillage: maize residue interactions upon soil water storage

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Four months before planting a crop of maize, a study was commenced on a well-drained clay loam soil to test the effect of tillage and surface maize residue on soil water storage. Tillage main plots were split into bare (residue...
  5. The effect of removing maize surface residue from the seed-row on seedzone temperature, soil water and maize development

    The effect of removing maize surface residue from the seed-row on seedzone temperature, soil water and maize development

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Early maize development is generally less rapid in the cooler soils of tillage systems which maintain large amounts of crop residues (stubble) on the soil surface. However, soil water storage tends to increase with increasing amount of surface cover, and...
  6. Effect of tied ridges on grain yield response of Maize (<em>Zea mays L.</em>) to application of crop residue and residual N and P on two soil types at Alemaya, Ethiopia

    Effect of tied ridges on grain yield response of Maize (<em>Zea mays L.</em>) to application of crop residue and residual N and P on two soil types at Alemaya, Ethiopia

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Field experiments were conducted on two soil types over a period of five years (1986ā€“1990) to investigate the effects of tied ridges and planting systems on the grain yield response of maize to applications of crop residue and residual N...
  7. Factors affecting runoff and soil loss under simulated rainfall on a sandy Bainsvlei Amalia soil

    Factors affecting runoff and soil loss under simulated rainfall on a sandy Bainsvlei Amalia soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This study was conducted on a long-term tillage experiment that was designed to evaluate appropriate tillage practices for sustainable dryland crop production. Measurements of runoff and soil loss were conducted on a sandy Bainsvlei Amalia soil (88.0% sand, 3.6% silt,...
  8. Analysis of Spray Aid's residue curve for timing fungicide applications for grey leaf spot on maize

    Analysis of Spray Aid's residue curve for timing fungicide applications for grey leaf spot on maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Maize grey leaf spot is still a problem in commercial maize production, although the effect has been reduced with the widespread use of resistant varieties. It is estimated that, with a yield reduction of 1 %, annual economic losses of...
  9. Tillage-crop residue management and rainfall-runoff relationships for the Alemaya catchment in Eastern Ethiopia

    Tillage-crop residue management and rainfall-runoff relationships for the Alemaya catchment in Eastern Ethiopia

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field study was conducted in the Alemaya catchment, Eastern Ethiopia, with the objective of determining the effect of tillage practices, crop reside cover and rainfall characteristics on runoff during two rainfall seasons on a clayey Regosol with 5% slope...
  10. The effects of a water treatment residue on grain yield and nutrient content in seeds of common dry beans (<em>Phaseolus vulgaris</em> L. cv. Ghadra) grown in a dystrophic soil

    The effects of a water treatment residue on grain yield and nutrient content in seeds of common dry beans (<em>Phaseolus vulgaris</em> L. cv. Ghadra) grown in a dystrophic soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This glasshouse study investigated the grain yield and nutrient content of seed of common dry beans (Phaseolus vulgaris L. cv. Ghadra) grown in a dystrophic sandy soil treated with 0, 50, 100, 200 and 400 g kgāˆ’1 water treatment residue...
