  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. Screening for DIMBOA (benzoxazinone) concentration among South African inbred maize lines and sorghum cultivars

    Screening for DIMBOA (benzoxazinone) concentration among South African inbred maize lines and sorghum cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Twenty-seven popular South African inbred maize lines, four commercial maize cultivars, two sweet corn cultivars and two grain sorghum cultivars were screened by means of a rapid, semi-quantitative method to determine DIMBOA concentration. Significant differences were found between inbred lines...
  3. 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...
  4. Comparisons of using fitted (calculated) and determined (measured) genetic coefficient G2 in CERES-Maize

    Comparisons of using fitted (calculated) and determined (measured) genetic coefficient G2 in CERES-Maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Genetic coefficients reflect simulated differences in cultivar growth and development. These are not readily available for most South African maize cultivars. They could either be fitted or determined experimentally. This study showed that the determined values of genetic coefficients are...
  5. Effects of four herbicides on the infestation of maize by the nematode <em>Pratylenchus zeae</em>

    Effects of four herbicides on the infestation of maize by the nematode <em>Pratylenchus zeae</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effects of atrazine, alachlor, EPTC and 2, 4-D on penetration and reproduction rate of Pratylenchus zeae on maize, were evaluated. The herbicides had no significant influence on the nematode populations.
  6. Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Effect of the amount of surface maize residue on infiltration and soil loss from a clay loam soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Six levels of maize stover, expressed as percentage ground cover (0–75%) were compared under a rainfall simulator to assess the effect of surface residues on infiltration and soil loss on a clay loam soil with a 3,5% slope. Increasing the...
  7. Growth responses of inbred maize lines with high and low DIMBOA (benzoxazinone) contents to atrazine

    Growth responses of inbred maize lines with high and low DIMBOA (benzoxazinone) contents to atrazine

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The growth response of five inbred maize lines with high and low DIMBOA content were compared in the presence of 3 and 12 ppm atrazine. A growth-promoting effect of atrazine on roots, mesocotyls and coleoptiles was observed in dark-grown seedlings...
  8. Practical means of scheduling irrigation of maize using a programmable pocket calculator

    Practical means of scheduling irrigation of maize using a programmable pocket calculator

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The irrigation scheduling model IRRISCHED-4, here described, enables the irrigator to choose one of four techniques for estimating crop water use, depending upon data available. Daily inputs include maximum and minimum temperatures, sunshine hours, leaf area index, crop factor, rain,...
  9. Potassium effects on stalk strength, premature death and lodging of maize (<em>Zea mays</em> L.)

    Potassium effects on stalk strength, premature death and lodging of maize (<em>Zea mays</em> L.)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In a field trial with maize, applications of potassium (K) proved to have a highly significant effect on stalk strength, premature death, root lodging and stalk breakage. A week prior to harvest the percentage of lodged plants varied from 77%...
  10. Importance of rainfall oscillations in agricultural planning

    Importance of rainfall oscillations in agricultural planning

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Evidence seems to indicate that the rainfall in the summer rainfall area of the RSA exhibits an oscillatory nature with a period of 16–20 years. To help maize farmers in planning for a dry or wet cycle the most recent...
