  1. Grazing of <em>raphanus sativus</em>. L (Japanese Radish)<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The performance of young woolled sheep was markedly better when grazing Japanese radish early in winter, when more leaf was available .Continuous grazing resulted in better performance than rotational or zero grazing.
  2. Crop rotation and tillage effects on yield and the incidence of root and stalk rot in sorghum (<em>Sorghum bicolor</em>)

    Crop rotation and tillage effects on yield and the incidence of root and stalk rot in sorghum (<em>Sorghum bicolor</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effect of six crop rotation systems, planted under conventional and reduced tillage, on root and stalk rot and grain yield of sorghum was studied. The systems were applied for five seasons until 1991/92 when the effects of the systems...
  3. The Application of Inorganic Fertilisers to Conditioned <em>Pinus radiata</em> Prior to Lifting as a Means of Improving Root Growth Capacity

    Item type: Journal Article • Journal: South African Forestry Journal
    A modified root growth capacity technique was used to evaluate the effect of the application of different types and quantities of fertilisers on the root growth capacity (RGC) of conditioned Pinus radiata seedlings. The experiment indicates that 0,05 g N...
  4. Root Systems of Some Southern Cape Indigenous Forest Trees

    Item type: Journal Article • Journal: South African Forestry Journal
    Root system form of forest trees were investigated and classified in the southern Cape indigenous forests. Windfalls of some of the dominant canopy species were inspected. Root systems were opened up by mechanical excavations. Tree species displayed the following general...
  5. The Use of Roots to Test N, P and K Deficiencies in <em>Eucalyptus</em> Nutrition

    Item type: Journal Article • Journal: South African Forestry Journal
    Bioassays have been developed which can provide diagnostics of the nutritional status of trees. They measure the flux of N, P or Rb for K into roots from standard solutions where the rate of influx is inversely related to nutrient...
  6. Root-shoot Growth Periodicity in <em>Ocotea bullata</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    Periodicity in leaf fall, and in the growth of roots and shoots of Ocotea bullata was studied. Leaf fall of canopy trees was measured to establish the natural phenological pattern of mature trees. Shoot growth was measured on potted plants...
  7. Evidence of Induced Nutrient Deficiency in Pine Plantings on Previously Cropped Lands

    Item type: Journal Article • Journal: South African Forestry Journal
    Widespread establishment failures of Pinus species have recently occurred on agricultural land acquired for commercial forestry in South Africa. These include about 10 000 ha of previously tilled soils in the north-eastern Cape belonging to Mondi Forests. A lettuce (Lactuca...
  8. Soil factors affecting tree growth and root development in a citrus orchard

    Soil factors affecting tree growth and root development in a citrus orchard

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Tree- and root-growth parameters correlated well with a number of soil properties Useful relationships were established between unconfined penetrometer resistance, air capacity (at FWC), tree growth and root development.
  9. Die wiskundige simulering van koolhidraattranslokasie in natuurlike grasveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die groeifunksies benodig vir die simulasie van produksie van ‘n Themeda triandra‐grasveld met behulp van die PUTU 11 simulasiemodel is ontwikkel. Vir die ontwikkeling van die model is die veldproduksiedata van die 1980/81 groeiseisoen gebruik waarna dit suksesvol, vir drie...
  10. Die invloed van die beskikbaarheid van nutriënte en ontblaringsbestuur op die produksie van <em>digitar1a Eriantha</em> variëteit <em>Eriantha</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die invloed van verskillende peile van stikstof (N), fosfaat (P) en kalium (K) op die produksie en kwaliteit van Digitaria eriantha var. eriantha is in sandkultuur ondersoek. Verder is daar ook gekyk na die invloed van drie intensiteite van ontblaring...
