  1. Managing cultivated pastures for improving soil quality in South Africa: challenges and opportunities

    Managing cultivated pastures for improving soil quality in South Africa: challenges and opportunities

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Loss of productive agricultural land due to soil degradation poses a serious threat to agricultural output and sustainability. Soil degradation of cultivated pastures manifests as a long-term decline in production potential. There are concerns that soils under pastures in certain...
  2. Soil water and mineral nitrogen content as influenced by crop rotation and tillage practice in the Swartland subregion of the Western Cape

    Soil water and mineral nitrogen content as influenced by crop rotation and tillage practice in the Swartland subregion of the Western Cape

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Adoption of conservation agricultural practices, reduced tillage and crop rotation in the grain-producing areas of the Western Cape, South Africa, resulted in a gradual build-up of organic matter on the soil surface. It was expected that the increase in organic...
  3. Crop rotation and tillage system effects on reducing ryegrass occurrence in spring wheat

    Crop rotation and tillage system effects on reducing ryegrass occurrence in spring wheat

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Under the Mediterranean climatic conditions of the Western Cape province, the Swartland region is intensively cropped, producing spring wheat (Triticum aestivum L.), but due to ryegrass competition, yield is reduced. In addition, ryegrass has developed resistance to herbicides. This necessitates...
  4. Impact of seasonal nitrogen fertilisation on production characteristics of a mixed grass pasture in the Western Cape province of South Africa

    Impact of seasonal nitrogen fertilisation on production characteristics of a mixed grass pasture in the Western Cape province of South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Pasture production in the Western Cape has traditionally been based on temperate species producing the majority of fodder during spring and autumn after which dry matter production decreases in winter. To investigate seasonal fertiliser nitrogen (N) management strategies to optimise...
  5. Allelopathic interaction between <em>Chenopodium album</em> L. and certain crop species

    Allelopathic interaction between <em>Chenopodium album</em> L. and certain crop species

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Laboratory and glasshouse studies were conducted to assess the allelopathic effect of Chenopodium album L. on the germination and early growth of certain crop species. Test species were grown in soils containing 1% (m/m) freeze-dried shoot material of the weed...
  6. The effect of chloride on four different citrus rootstocks

    The effect of chloride on four different citrus rootstocks

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Seedlings of Troyer citrange [Poncirus Mollata L. Raf. × Citrus sinensis L. Osbeck] (Tro), Citrus volkameriana (Vol), Carrizo citrange [Poncirus trifoliata L. Raf. × Citrus sinensis L. Osbeck], (Car) and Rough lemon [Citrus jambhiri Lush.] (Rie) were tested for tolerance...

  9. A comparison of HMW-GS, LMW-GS and RAPD fingerprinting for cultivar identification of some South African wheat cultivars

    A comparison of HMW-GS, LMW-GS and RAPD fingerprinting for cultivar identification of some South African wheat cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Accurate identification of breeding material is very important for the plant breeder. In South Africa, high molecular weight glutenin subunits (HMW-GS) have so far been used for wheat cultivar identification. This method can often not distinguish between cultivars, and other...
