  1. Genetic parameters for large white pigs reared under intensive management systems in Kenya

    Genetic parameters for large white pigs reared under intensive management systems in Kenya

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    A lack of performance parameters is one of the factors limiting the implementation of sustainable breeding strategies for the pig industry in Kenya. The objective of this study was to estimate genetic and phenotypic parameters for growth performance of Large...
  2. A comparison of grass and grass/legume pastures under irrigation in the Outeniqua area of the southern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Two grass and five grass/legume pastures were evaluated over a period of two seasons at two seasonally set grazing pressures and under two grazing management systems, involving five and seven paddocks per flock and a seven‐day period of stay. Grazing...
  3. A comparison of four different standards of reference for the animal unit for Determining stocking rate

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    No single standard of reference for the animal unit (AU) for determining stocking rates has materialized. Often, therefore, it is not clear which standard of reference for the AU or which method of determining stocking rate has been used in...
  4. The herbage yield and quality of three grass species on two marginal maize soils at Potchefstroom

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A small plot experiment with Digitaria eriantha, Panicum maximum and Anthephora pubescens, established on Valsrivier and Westleigh soil forms, was conducted at Potchefstroom during the 1986/87 and 1987/88 seasons. The yield of P. maximum was the highest of the three...
  5. The influence of lime and phosphorus on the growth of white clover on highly weathered Natal soils

    The influence of lime and phosphorus on the growth of white clover on highly weathered Natal soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Results of field studies conducted on highly weathered Natal soils in which the performance of white clover (Trifolium repens cv. Regal ladino) was examined under a range of lime and P treatments applied in factorial combination, are presented. Despite adverse...
  6. The effects of strategic nitrogen fertiliser application during the cool season on perennial ryegrass-white clover pastures in the Western Cape Province 1. Soil nitrogen dynamics

    The effects of strategic nitrogen fertiliser application during the cool season on perennial ryegrass-white clover pastures in the Western Cape Province 1. Soil nitrogen dynamics

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The dynamics of soil inorganic-N in reaction to a single, strategic application of fertiliser N were studied during the period 2000 to 2002 in an Oakleaf soil with a clay content increasing from 10 to 30.8% with depth. Soil inorganic-N...
  7. The effects of strategic nitrogen fertiliser application during the cool season on perennial ryegrass-white clover pastures in the Western Cape Province 2. Dry matter production

    The effects of strategic nitrogen fertiliser application during the cool season on perennial ryegrass-white clover pastures in the Western Cape Province 2. Dry matter production

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The response of an irrigated perennial ryegrass-white clover pasture to fertiliser nitrogen application rates of 0, 50, 100 and 150 kg N ha−1 applied in either autumn, early winter, late winter, early spring or late spring was investigated over a...
  8. The effects of strategic nitrogen fertiliser application during the cool season on perennial ryegrass-white clover pastures in the Western Cape Province 3. Clover content

    The effects of strategic nitrogen fertiliser application during the cool season on perennial ryegrass-white clover pastures in the Western Cape Province 3. Clover content

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The influence of a single application of fertiliser N (0, 50, 100 and 150 kg N ha−1) applied in either autumn, early winter, late winter, early spring or late spring on the grass-clover balance in a perennial ryegrass-white clover pasture...
  9. Using canonical variate analysis to group small white bean cultivars canned in tomato sauce according to their canning quality

    Using canonical variate analysis to group small white bean cultivars canned in tomato sauce according to their canning quality

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A laboratory-scale canning and evaluation method was employed to evaluate the canning quality of small white beans over cultivars, localities and seasons. Four small white bean cultivars, representing 15 localities from the 2001/02 season and six cultivars representing 17 localities...
  10. A canning quality model for small white bean lines selected for breeding (P<em>haseolus vulgaris</em> L.)

    A canning quality model for small white bean lines selected for breeding (P<em>haseolus vulgaris</em> L.)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The study aimed to validate canonical variate analysis (CVA) model equations for the grouping of small white beans according to canning quality by testing them on four cultivar samples of known canning quality (2000/01 season), and 24 breeding samples that...
