  1. Invloed van N-bemesting en rhizobiumrasse op opbrengs en N-samestelling van die saad van sojabone (<em>Glycine max</em>)

    Invloed van N-bemesting en rhizobiumrasse op opbrengs en N-samestelling van die saad van sojabone (<em>Glycine max</em>)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die studie is onderneem om die invloed van twee faktore, N-bemesting en atmosferiese N-binding, op opbrengs en proteïengehalte van Suid-Afrikaanse sojabone vas te stel. Drie N-misstowwe (ureum, NH4 +, NO3 −) met 15N verryk, is in 'n potproef teen 20...
  2. Intraspecific variability: an important consideration in forming generalisations about toxigenic algal species

    Intraspecific variability: an important consideration in forming generalisations about toxigenic algal species

    Item type: Journal Article • Journal: African Journal of Marine Science
    Intraspecific variability (strain differences) in key characteristics such as life-history traits, behaviour, nutrition, genetics and toxicity, has been experimentally documented for many toxigenic microalgae, including species of cyanobacteria, dinoflagellates, haptophytes, raphidophytes and diatoms. This paper summarises findings from published studies...
  3. Effects of kelp <em>Ecklonia maxima</em> inclusion in formulated feed on the growth, feed utilisation and gut microbiota of South African abalone <em>Haliotis midae</em>

    Effects of kelp <em>Ecklonia maxima</em> inclusion in formulated feed on the growth, feed utilisation and gut microbiota of South African abalone <em>Haliotis midae</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    The effect of kelp Ecklonia maxima inclusion in formulated feeds on abalone growth and gut bacterial communities has not been previously investigated in South Africa. An eight-month on-farm growth trial was conducted with sub-adult Haliotis midae (∼43 mm shell length)...

    Effect of cassava starch on shrinkage characteristics of concrete<xref ref-type="fn" rid="FN0000"/>

    The use of starch and its derivatives in concrete as an admixture to modify relevant properties of concrete has been on the increase in recent times. It is known to modify the rheology, affect the hydration kinetics of cement, and...
