  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. 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...
  4. Release of cotton breeding lines (<em>Gossypium hirsutum</em> L.) adapted to South African conditions

    Release of cotton breeding lines (<em>Gossypium hirsutum</em> L.) adapted to South African conditions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The cotton breeding programme of the Tobacco and Cotton Research Institute has made available a number of advanced breeding lines and cultivars of cotton for a second cycle of intercrossing and selection. Selati, Gariep and NIK3 have been released for...
  5. Genotypic variation in leaf water potential of field-grown soybeans (<em>Glycme max</em> L. Merr.) and its association with dryland yield

    Genotypic variation in leaf water potential of field-grown soybeans (<em>Glycme max</em> L. Merr.) and its association with dryland yield

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Maintenance of leaf water potential (ΨL) during periods of water stress may constitute an important drought-avoiding response. The identification of genotypic variation for this characteristic is, however, made difficult by the fact that comparative values for ΨL must be measured...
  6. Macadamia cultivar evaluation in Natal

    Macadamia cultivar evaluation in Natal

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Vegetatively propagated macadamia cultivars were grown in six ecologically different areas in Natal. Nut quality was tested over a number of years. The warm, moist north coast area is best for most cultivars tested with Keaau, Ka'u, Kakea and Beaumont...
  7. 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...
  8. Damage caused by <em>Chilo partellus</em> (Swinhoe) (Lepidoptera: Pyralidae) to various cultivars of grain sorghum, <em>Sorghum bicolor</em> (L.) Moench

    Damage caused by <em>Chilo partellus</em> (Swinhoe) (Lepidoptera: Pyralidae) to various cultivars of grain sorghum, <em>Sorghum bicolor</em> (L.) Moench

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Grain sorghum cultivars differed significantly in yield response to natural Chilo partellus infestations over a period two seasons. These differences were ascribed to cultivar characteristics of which differences in length of growing season requirements were the most important. Differences in...
  9. Registration of cotton (<em>Gossypium hirsutum</em> L.) cultivars Letaba, NIK2 and OR19

    Registration of cotton (<em>Gossypium hirsutum</em> L.) cultivars Letaba, NIK2 and OR19

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Letaba, NIK2 and OR19 were released for commercial cultivation in the R.S.A. in 1989. Letaba has potential as a dryland cultivar in the Springbok Flats and northern Natal. NIK2 is intended for cultivation under irrigation in the same areas and...
  10. Differensiële fitotoksisiteit van tralkoksidim, bromoksinil en 'n mengsei van die twee produkte op Suid-Afrikaanse koringcultivars

    Differensiële fitotoksisiteit van tralkoksidim, bromoksinil en 'n mengsei van die twee produkte op Suid-Afrikaanse koringcultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Twee glashuisproewe en een veldproef is uitgevoer om die gevoeligheid van koringcultivars vir die wilde-haweronkruiddoder tralkoksidim, die breëblaaronkruiddoder bromoksinil en 'n mengsel van die twee te bepaal. Waar tralkoksidim teen dubbel die hoogste aanbevole dosisse met die benatter Addit(R) in...
