  1. Effect of pruning on yield and quality of hydroponically grown cherry tomato (<em>Lycopersicon esculentum</em>)

    Effect of pruning on yield and quality of hydroponically grown cherry tomato (<em>Lycopersicon esculentum</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The commercial importance of cherry tomatoes is continuously increasing in the South African retail market, with fruit size playing an important role. The effect of pruning on yield and quality of two cherry tomato cultivars (Naomi and Josefina) with an...
  2. Comparative performance of tomato cultivars cultivated in two hydroponic production systems

    Comparative performance of tomato cultivars cultivated in two hydroponic production systems

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Cultivar selection for different hydroponic production systems is an important management decision, potentially impacting the tomato grower’s profitability. Knowledge on the performance of tomato cultivars, in specific hydroponic systems (open-bag and closed system) under South African conditions, is still very...
  3. Potential of Adelaide, Cradock and Middelburg, South Africa, for out-of-season onion production using different planting materials and planting dates

    Potential of Adelaide, Cradock and Middelburg, South Africa, for out-of-season onion production using different planting materials and planting dates

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Out-of-season onion production is used to produce onions for the early market (April to September) when onion prices peak. No information with regard to this production method is available for the Eastern Cape. Field experiments were therefore conducted in Adelaide,...
  4. Effect of Seed Tuber Planting Depth and Nitrogen Rate on Yield and Yield Related Traits of Potato (<em>Solanum tuberosum</em> L.) at Haramaya and Hirna, Eastern Ethiopia

    Effect of Seed Tuber Planting Depth and Nitrogen Rate on Yield and Yield Related Traits of Potato (<em>Solanum tuberosum</em> L.) at Haramaya and Hirna, Eastern Ethiopia

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    The potato (Solanum tuberosum L.) is an important cash and food security crop in the eastern highlands of Ethiopia. However, the yield of the crop is constrained by low soil fertility and poor agronomic practices. Therefore, the field experiment was...
  5. Impact of Wood Quality Assessments on Future Fibre Resources in the Pulp and Paper-making Industry

    Item type: Journal Article • Journal: South African Forestry Journal
    Recent evidence from research in Europe has indicated that individual trees can be sampled for their pulping properties by the removal of small quantities (5–50 g) of wood at about breast height (1,3 m above ground). Work began at Sappi's...
  6. 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...
  7. The performance of tropical pastures in the drier phase of the Highland sourveld of Natal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Several tropical grasses (Acroceras macrum, Cenchrus ciliaris, Cyndon sp., Digitaria sp. and Pennisetum clandestinum) and legumes (Desmodium uncinatum and Lotononis bainesii) were evaluated at the Kokstad Research Station (Bioclimatic sub‐region 4f of Natal) over a period of seven years. The...
  8. Long term nitrogen and phosphorus application to veld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The long term effects of a 5N x 3P factorial fertilizer application trial on hay yields, botanical composition and soil properties of veld are presented. Significant increases in hay yields were recorded during most years. There was a strong correlation...
  9. Growth patterns of Italian ryegrass cultivars established in different seasons

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A comparison is made between various Italian ryegrass cultivars established under irrigation on a well‐drained upland site during the traditional autumn months, with plantings of the same cultivars at other times of the year.
  10. Production and quality norms of certain grass species for fodder flow planning: Pretoria area

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four subtropical (Cenchrus. Digitaria, Anthephora and Sorghum) and two temperate grass species (Festuca. Agrotricum) were grown in a replicated field experiment at three levels of N application, with adequate P and K. Species were mown at 4‐, 6‐ and 8‐weekly...
