  1. Invloed van bemesting op die oliekonsentrasie oliekwaliteit van sonneblomsaad

    Invloed van bemesting op die oliekonsentrasie oliekwaliteit van sonneblomsaad

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Influence of fertilization on the oil concentration and oil quality of sunflower seed. Fertilizer trials (N,P,K and lime) were conducted over two seasons at three localities. Results indicate that 150 kg N ha−1 fertilizer decreased the oil concentration of the...
  2. The application of various chemicals to cuts made in the stem bases of <em>Brachystegia spiciformis</em> Benth., <em>Julbernardia globiflora</em> (Benth.) Troupin and <em>Terminalia sericea</em> Burch. ex DC.

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Picloram‐potassium and various mixtures of picloram with 2,4‐D amine, 2,4,5‐T ester or amine, or 2,4,5‐T ester alone were injected into incisions made in the cambium of standing Brachystegia spiciformis and Julbernardia globiflora trees. Each arboricide was tested at a range...
  3. Groei en chemiese samestelling van verskillende peulgewasse onder suurgrondtoestande

    Groei en chemiese samestelling van verskillende peulgewasse onder suurgrondtoestande

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die groei van verskillende peulplantspesies is op twee suur bogronde by 'n baie lae vlak van Ca-voorsiening, as hidroksied en sulfaat, in 'n glashuis ondersoek. Die hidroksiedbehandelings, wat met 'n mate van pH-styging gepaard gegaan het, het die beste resultate...
  4. Effect of simulated acid rain and sulphur nutrition on the growth, sulphate and cation content of <em>Bromus diandrus</em> Roth.

    Effect of simulated acid rain and sulphur nutrition on the growth, sulphate and cation content of <em>Bromus diandrus</em> Roth.

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Bromus diandrus seedlings were grown in sand culture under greenhouse conditions, using a two factor randomized block design. Two levels of sulphur nutrition (with and without) and three acid rain treatments were applied. The plants were harvested 45 days after...
  5. Performance of five soybean cultivars in relation to lime and phosphorus levels on an acid Ultisol

    Performance of five soybean cultivars in relation to lime and phosphorus levels on an acid Ultisol

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The seed-yield response of five soybean cultivars (Hill, Geduld, Forrest, Welkom and Oribi) to applications of lime [Ca(OH)2] and P was evaluated over two seasons in the field on an acid soil of the Normandien series (Plinthic Paleudult). As a...
  6. Gentisic acid concentration in healthy and greening infected fruit albedo and leaves of citrus species and cultivars

    Gentisic acid concentration in healthy and greening infected fruit albedo and leaves of citrus species and cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Gentisic acid was shown to be present in citrus leaves and fruit albedo irrespective of tolerance or susceptibility of different cultivars and species to greening disease. There was no linearity between gentisic acid concentration and observed tolerance or susceptibility. An...
  7. 'n Vergelyking van verskillende metodes vir die ekstraksie en bepaling van aluminium in grond

    'n Vergelyking van verskillende metodes vir die ekstraksie en bepaling van aluminium in grond

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Vier metodes vir die ekstrahering en bepaling van Al in suur gronde is vergelyk vir grondmonsters vanaf 'n verskeidenheid van bronne en met pH (KCl) waardes tussen 3,3 en 4,4. Die oogmerk was om 'n vinnige, eenvoudige, maar steeds betroubare...
  8. Inoculation of cowpea and wheat with strains of <em>Bradyrhizobium</em> sp. that differ in their production of indole acetic acid

    Inoculation of cowpea and wheat with strains of <em>Bradyrhizobium</em> sp. that differ in their production of indole acetic acid

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Sufficient indole acetic acid (IAA) was produced in yeast extract-mannitol (YM) medium by each of two isolates of indigenous Bradyrhizobium sp., to inhibit primary root growth of cowpea. Similar inoculation of cowpea with YM-cultivated strains from a culture collection or...
  9. A multivariate approach to a specific problem of grouping maize cultivars

    A multivariate approach to a specific problem of grouping maize cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The use of multivariate techniques in the analysis of multivariate problems is illustrated by comparing the results of univariate and multivariate techniques applied to the problem of establishing the nutritional requirements of, and the acid tolerance differences between maize cultivars...
