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.

New head for Student Academic Services
2009-03-05

The University of the Free State (UFS) has appointed Mr Frank Madimetja Nkoana, pictured, as the new Director of Student Academic Services (SAS).

Mr Nkoana has a wealth of experience having worked for 24 years in the field of academic administration, 14 of which have been in leadership and senior management positions, at various institutions of higher learning.

In this post he will supervise applications, admissions, financial aid and registrations through to graduations.

The Director: Student Academic Services has a pivotal role to play in developing and supporting the University’s educational agenda.

“I consider my appointment to the Division as the correct one at the right time and a blessing to the UFS in view of my experience and training in the field of academic administration,” he said.

He believes it is only through effective and efficient academic support services that the institution can achieve excellence in its academic endeavour in tandem with its vision of being “an excellent, equitable and innovative University”.

“I must see to it that SAS, as both a sector and a process, is sufficiently and appropriately supported and maintained through an effective administrative structure that is manned by skilled and well-trained personnel, adding thereto continuous development and job enhancement – thus creating a conducive environment for efficiency and effective service delivery to students, staff and the wider community,” he said.

However, he is also mindful of the challenges facing him and the Division. He considers as his main challenge, among others, the creation of a Division that is functionally able and has as its goal the achievement and provision of effective academic administrative support to the core university business.

“Our operations should be in line with new developments in academic administrative systems to enable the UFS to achieve academic excellence and global competitiveness,” said Mr Nkoana.

“We must be able to establish and strengthen a high level of ethos of service delivery and develop good human relations between the staff and the students.”
