  1. Assessment of aluminium tolerance in maize using a rapid screening procedure

    Assessment of aluminium tolerance in maize using a rapid screening procedure

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Routine testing for Al tolerance requires that screening procedures be both rapid and simple. Growth-chamber techniques, developed in the USA, show considerable promise in this regard and were used in this study to compare the Al tolerance of 10 maize...
  2. A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field experiment was conducted on a Normandien clay loam (Plinthic Paleudult) to compare the acid tolerance of 48 commercially grown maize (Zea mays L.) cultivars. Cultivars were compared in terms of grain yield, plant height and leaf Al content...
  3. Season and phosphorus age effects on the relationship between maize yield and phosphorus soil test on a highly weathered soil

    Season and phosphorus age effects on the relationship between maize yield and phosphorus soil test on a highly weathered soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This paper discusses data obtained from a long-term N, P, K field experiment with maize (Zea mays L.) on a Normandien clay loam (Plinthic Paleudult) near Newcastle, Natal. After eight seasons plots were split, sub-plots being allowed either to rundown...
  4. Are soil-borne diseases depressing yields of continuously-grown maize in Natal?

    Are soil-borne diseases depressing yields of continuously-grown maize in Natal?

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Long-term field trials suggest that yields are declining where maize (Zea mays L.) is grown continuously in some parts of Natal. Available evidence indicates that the decline is not ascribable to soil fertility or climatic constraints and the possibility exists...
  5. Soil and plant potassium optima for maize on a kaolinitic clay soil

    Soil and plant potassium optima for maize on a kaolinitic clay soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In South Africa, there is an extreme paucity of information relating maize (Zea mays L.) yields to soil and plant K levels and most K fertilizer recommendations are highly subjective. Controversy also surrounds the practice of relating K fertilizer recommendations...
