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.

Kovsie first-years get ready for great things

“One thing I can assure you: here academic work comes first.” This was how Prof. Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), set first-years parents’ minds at ease during the welcoming events of the first-years on the Main Campus the past weekend. 

The welcoming events, which took place over two days, were attended by a total of 7 000 first-years and their parents from across the country. 
 
Prof. Jansen also told the students and their parents that they were at the best place, by sharing his excitement about all the new students who decided to come and study at Kovsies. “You have overcome major obstacles in order to be here today,” he said at the welcoming.
 
With more than 90% new students who comply with admission requirements, this group of students promises to become true leaders of South Africa.
 
Prof. Jansen shared a few plans for the year with the audience. “As in 2010, we shall once again send a group of first-year students to universities later this year, not only in America, but amongst others also to Europe and Asian countries, amongst others, to learn more about different cultures and diversity. We aim to double the number of students who will be selected to 150 this year.” We can also look forward to, amongst others, a brand-new entrance and gymnasium for the Main Campus and four new hostels, two of which will be built on the Qwaqwa Campus.
 
Prof. Jansen emphasised the seriousness with which academic work had to be regarded, by referring to the compulsory class attendance that was implemented last year. “Since the inception of this arrangement in 2010, there was a 30% increase in students’ pass rate,” he said.
 
This year, for the first time, honorary awards were also given to young people who had rendered an exceptional service to the community. Anél Kleingeld, a 10-year-old learner from Trompsburg, and Mpho Phahlo from the UFS’s Unit for Students with Disabilities proudly received these awards. Anél made a remarkable contribution to George’s community when she encouraged learners from her` school to collect and deliver 700 litres of water for this community. Mpho made a point of assisting and motivating persons with disabilities at Kovsies to work hard on a daily basis.
