Expansion of the crop to the other eight provinces is advocated to reduce a shortage of locally produced plant oils. Moreover, canola can serve as a rotational crop for wheat in the summer rainfall provinces. In the central Free State, agronomic information for canola production is lacking. An experiment with a line source sprinkler irrigation system was conducted to establish the influence of water application levels (175, 233, 295, 351 and 420 mm) in combination with plant densities (25, 50, 75, 100 and 125 plants m−2) on yield responses, yield components and growth parameters of canola. Seed (653–4653 kg ha−1) and stover (1983–6733 kg ha−1) yields induced by the treatment combinations proved that canola has a high level of plasticity. Over the full range of water application levels, highest seed and biomass yields were realised at densities of 25 and 75 plants m−2, respectively. The compensation of yields at lower plant densities was due to the production of more branches, pods and seeds per plant. Under full irrigation, densities of 25 and 75 plants m−2 are optimal for seed and biomass production, respectively.","PeriodicalId":21920,"journal":{"name":"South African Journal of Plant and Soil","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41419878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, there is limited information on resistance in potato cultivars in South Africa against brown leaf spot. This study aims to evaluate ten commercial potato cultivars for brown leaf spot resistance using detached leaf, tuber and whole plant screening techniques under controlled conditions. The experiment was conducted in 2016 and repeated in 2017. The whole plant assay showed that Labadia, Almera, Sifra, Mondeo, Up-To-Date and Lanorma are resistant to brown spot. Resistance levels in Labadia, Almera, Sifra and Up-To-Date were consistent in the 2016 and 2017 experiments. The detached leaf assay showed Almera, Sifra, Up-To-Date and Mondeo as moderately resistant, while Innovator, Mondial and Markies were moderately susceptible. However, in the tuber assay all cultivars were highly susceptible. Cultivar resistance varied based on the screening technique used, although results suggest that the detached leaf and whole plant assays could be used in potato disease screening programs.","PeriodicalId":21920,"journal":{"name":"South African Journal of Plant and Soil","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46559545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The last two to four leaching events released additional Mn. Higher SW concentrations significantly increased retention of Mn, Al, extractable Mn and acidity, and lowered pH in the soils.

In this study, a simplified, multi-layered soil water balance model to estimate daily soil moisture at point-scale from standard weather data and minimal physical soil properties was developed. The model requires values for soil water retentivity properties such as wilting point, field capacity and saturation of each soil layer. It also requires measurements or estimates of reference evapotranspiration (ETo ) in addition to rainfall as climate inputs. The developed model was evaluated using point-scale in-situ soil moisture measurements acquired over a minimum of two years from three well-calibrated stations representing different soil types and climatic conditions in South Africa. The results indicate that the proposed model was capable of estimating total soil moisture content at all three sites, with coefficient of determination (r 2) values greater than 0.84, index of agreement (d) values greater than 0.95 and root mean square error (RMSE) values less than 7.30 mm.

The alternative in many cropping situations is paraquat. After many years of success, neither herbicide could control plantago (Plantago lanceolata L., also ‘English plantain’) in Robertson. A survey was carried out by sending a questionnaire to agrichemical personnel to document the areas with poor plantago control using glyphosate and paraquat in the Western Cape province of South Africa. Recipients were asked to list localities with plantago not eliminated by glyphosate and paraquat, plantago populations that are not controlled by other herbicides apart from glyphosate and paraquat, other herbicides apart from glyphosate and paraquat that eliminate plantago, the history of herbicides applied in those areas and the total number of hectares involved. Survey data were obtained for 21 areas, which spanned over 6 583 ha. There were minimal differences in the type of herbicides applied in the different areas across the province. Most of the respondents reported that both glyphosate and paraquat were failing to control plantago. It appears as if the occurrence of difficult-to-control plantago is more widespread than initially thought. In future, a more detailed survey encompassing the entire country should be carried out to assess the extent of this problem. This will allow weed management strategies to be prioritised to deal with the troublesome plantago weed.","PeriodicalId":21920,"journal":{"name":"South African Journal of Plant and Soil","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47932518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was conducted as a split-plot design with three replications. Planting dates were the whole plot treatments, while varieties constituted the sub-plot treatments. The sub-plot treatments were laid out in a randomised complete block design.
