  1. Seed quality characteristics of a bambara groundnut (<em>Vigna subterranea</em> L.) landrace differing in seed coat colour

    Seed quality characteristics of a bambara groundnut (<em>Vigna subterranea</em> L.) landrace differing in seed coat colour

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Bambara groundnut (Vigna subterranea L.) is an underutilised African legume that fits the same ecological niche as Arachis hypogea. It is still cultivated using landraces and little is known about their seed quality. The current study evaluated seed quality characteristics...
  2. Seed quality of selected bottle gourd landraces compared with popular cucurbits

    Seed quality of selected bottle gourd landraces compared with popular cucurbits

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Bottle gourd (Lagenaria siceraria (Molina) Standl.) is an indigenous crop that is available only as landraces in sub-Saharan Africa, although it has a great potential for food security. Pumpkin (Cucurbita maxima L.) and cucumber (Cucurbita pepo L.) are exotic crops...
  3. Potential of producing green mealies in summer and winter at two sites in KwaZulu-Natal, South Africa, considering rainfall, soil moisture and weeding

    Potential of producing green mealies in summer and winter at two sites in KwaZulu-Natal, South Africa, considering rainfall, soil moisture and weeding

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Producers are exploring possibilities of growing major crops outside the normal growing seasons due to environmental challenges associated with climate change. This study evaluated growth and yield of maize (Zea mays ‘SC701′) in relation to planting season and weeding. Field...
  4. Determination of optimum ethylmethanesulfonate conditions for chemical mutagenesis of selected vernonia (<em>Centrapalus pauciflorus</em>) accessions

    Determination of optimum ethylmethanesulfonate conditions for chemical mutagenesis of selected vernonia (<em>Centrapalus pauciflorus</em>) accessions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Chemical mutagenesis could potentially increase allelic diversity and address genetic erosion in vernonia (Centrapalus pauciflorus) breeding programmes. The objective of this study was to determine an optimum treatment combination, i.e. exposure duration, temperature and ethylmethanesulfonate (EMS) dose that would reduce...
  5. Can molybdenum reduce pre-harvest sprouting in wheat?

    Can molybdenum reduce pre-harvest sprouting in wheat?

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effect of foliar application of molybdenum (Mo) on grain dormancy was examined in six wheat cultivare at four sites. Application of 100 mg L−1 Mo at flag leaf stage significantly increased grain Mo content at all sites and reduced...
  6. Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. I. Cotyledonal cracking

    Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. I. Cotyledonal cracking

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Cotyledonal cracking is a physiological disorder, which appears as one or a few transverse fissures across legume seed cotyledons early during seed germination or seedling emergence. The fissures hinder translocation of nutrients to the developing seedling and cause stunted seedling...
  7. Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. II. Stand establishment, chlorophyll fluorescence and yield

    Comparison of osmopriming and seed coating with calcium salts for green bean performance under field conditions. II. Stand establishment, chlorophyll fluorescence and yield

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Seed coating is commonly used to supply fungicides and micronutrients to enhance seed quality. The primary reason for using mineral elements in seed priming is to regulate water absorption. Osmopriming and seed coating were compared for their effect on crop...
  8. Temperature and light requirements for the germination of <em>Cleome gynandra</em> seeds

    Temperature and light requirements for the germination of <em>Cleome gynandra</em> seeds

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Seeds of Cleome (Cleome gynandra L.) are characterised by low germination and may require after-ripening. The dormancy characteristics and optimum conditions for seed germination of this species have not been explained. The objective of this study was to investigate the...
  9. Statistical evaluation of the germination of <em>Cleome gynandra</em> L. seeds

    Statistical evaluation of the germination of <em>Cleome gynandra</em> L. seeds

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Radicle protrusion and subsequent seedling establishment are two ways of defining seed germination. However, international rules for testing seeds adopted the first and final counts through consensus as defining stages of seed germination. In this study statistical guidelines have been...
  10. Effect of indigenous storage method on performance of taro [<em>Colocasia esculenta</em> (L.) Schott] under field conditions in a warm subtropical area

    Effect of indigenous storage method on performance of taro [<em>Colocasia esculenta</em> (L.) Schott] under field conditions in a warm subtropical area

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Successful crop stand establishment, a critical prerequisite for efficient crop production, is primarily determined by propagule quality. Taro [Colocasia esculenta (L.) Schott] corms of different sizes (80–100 g corm−1, 40–60 g corm−1 and 20–30 g corm−1) that had been stored...
