Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.
Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

Harmony contributes to Right to Learn campaign

Harmony, a residence of the University of the Free State (UFS), recently used a breakfast for academic achievement to also make a contribution to the Right to Learn Campaign. The first-year residence on the Bloemfontein Campus of the UFS donated R6 300 to the campaign, which was started in response to the dire need for financial relief for academically deserving students from underprivileged backgrounds.

 

On 9 April 2016, the event was concluded with a Right to Learn poem and the handover of a cheque to the Student Representative Council (SRC) towards the campaign. The SRC launched the Right to Learn campaign on 30 October 2015 as a supplementary initiative to the #FeesMustFall movement. The proceeds will be channelled towards reducing the number of students who will face de-registration in 2016, to the SRC textbook bursary, and to food bursaries.

 

According to Pulane Malefane, Head of Harmony Residence, the breakfast was held to celebrate the academic achievements of the residence. Harmony prides itself on academic excellence, and instils this value into its first years at the beginning of the year.

The best academic achievers were recognised, according to their performance during matric. This was done in order to encourage the students to keep on excelling at university.

Harmony also acknowledged its student leaders motivating the first–year students.
