The UFS presented a number of special awards during the graduation ceremonies on its Bloemfontein Campus on 27 and 28 June 2019. 

Jannie de Villiers earns UFS Chancellor’s Medal

Chief Executive Officer of Grain SA and recipient of the 2019 Chancellor’s Medal, Jannie de Villiers, is a renowned leader in the agricultural and food sectors, nationwide and globally. He started his career as an economist for the South African Department of Agriculture in 1985, and dedicated more than 30 years of his knowledge, skills, and leadership to the agricultural sector, specifically in grain-industry development. 
Mr De Villiers is commended for a number of initiatives he has implemented to enrich people’s lives throughout his career. One of his many admirable achievements is equipping upcoming farmers with the necessary knowledge and practical skills to advance crops and establishing a sustainable livelihood for South African citizens in the process.

UFS Council honours Elzmarie Oosthuizen

Council Medal recipient, Elzmarie Oosthuizen, is the Director: Centre for Excellence in Teaching and Learning in the UFS Faculty of Natural and Agricultural Sciences (NAS). 
Oosthuizen’s experience and leadership in foundation and bridging programmes are exceptional. She has successfully initiated a programme to promote teaching and learning in Mathematics, Natural Sciences, Economics, and Agricultural subjects. Due to her active involvement in managing foundational and bridging programmes for students who do not meet the minimum requirements for mainstream higher-education degrees in NAS, the pass rate of the BSc bridging programme has increased from 34% to 83%. 

“This award inspires me to sustain my efforts and find extraordinary solutions for the challenging and complex scenarios that we are facing in higher education,” said Ms Oosthuizen. 

UFS June graduation Dean’s Medal recipients

Michelle Nöthling (Master of Arts in Africa Studies) in the Faculty of the Humanities and Megan Braithwaite (Master of Arts in Theology with specialisation in Bible Translation) in the Faculty of Theology and Religion were awarded Dean’s Medals on the morning of 28 June 2019. The Faculty of Education also honoured Deborah Lynn Fair, who achieved the best results for her master’s degree in Education with specialisation in Curriculum Studies, with a Dean’s Medal.

On the afternoon of 28 June, Teboho Mooko (Master of Medical Science with specialisation in Pharmacology) received the Dean’s Medal in the Faculty of Health Sciences. Tshanduko Mutandanyi (Master of Science majoring in Geohydrology) received the Dean’s Medal in the Faculty of Natural and Agricultural Sciences, as well as the Senate Medal for the best overall results in both under- and postgraduate qualifications in all the UFS faculties.

Dr Khotso Mokhele hosts Chancellor’s Dinner

Later that evening, the Chancellor of the UFS, Dr Khotso Mokhele, hosted the Chancellor’s Dinner in the Centenary Complex on the UFS Bloemfontein Campus, paying tribute to the outstanding achievements of the recipients of UFS honorary doctorates, Council and Chancellor’s medals, and doctorates. 

Among the honoured guests were the two honorary doctorate recipients, Dr Jerry Mofokeng wa Makhetha – world-renowned, respected television and theatre actor (DLitt Honoris Causa – Faculty of the Humanities), and Dr Bernie Fanaroff (DSc Honoris Causa – Faculty of Natural and Agricultural Sciences), who is the Co-chair of the BRICS (Brazil, Russia, India, China and South Africa) Working Group on Information and Communication Technologies and High-Performance Computing, and member of the Advisory Committee of the Breakthrough Listen project; Mr Jannie de Villiers; Ms Elzmarie Oosthuizen; the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen; and Mr Willem Louw, Chairperson of the UFS Council.

Guests also enjoyed a musical performance by the Graduation Instrumental Ensemble under the direction of Anton Esterhuyse, accompanied by the vocal ensemble of Thabo Hlongwane, Jacobus Silwer, and Mario Lategan.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
