UFS Research scholars celebrated at the annual research awards

The University of the Free State (UFS) recently hosted its annual Research Awards function at the Wynand Mouton Theatre on the Bloemfontein campus. Present at this event on 26 September 2023 were Prof Francis Petersen, the Vice-Chancellor and Principal of UFS, Prof Crain Soudien, a globally renowned academic and the President of the Cornerstone Institute, and members of the UFS academic community, among others. 

The awards ceremony

Prof Petersen stated, ‘’The purpose of the event is to recognise scholars at the University of the Free State who are conducting outstanding research in their respective fields of expertise.’’ Certificates were presented to researchers in various categories, including National Research Foundation (NRF) Rated Scholars from categories P to A.  Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the UFS, highlighted that there are precisely 217 NRF-rated scholars within the institution. However, some of these scholars had not been acknowledged internally. Hence, the ceremony aimed to celebrate these scholars.

Furthermore, UFS staff members were acknowledged for their research at both national and international levels. Prof Abdon Atangana, named as one of five recipients of the inaugural UNESCO-Al Fozan International Prize for the Promotion of Young Scientists in Science, Technology, Engineering and Mathematics (STEM), was among these individuals. Future professors of the institution who are part of the Professoriate Programme were also recognised for their outstanding performance in transforming the programme.

The highly anticipated category of the evening was the UFS Book Prize for distinguished scholarship. Prof Reddy explained, ‘’the purpose of the award is to recognise outstanding publications produced by any permanent member of the UFS staff, which are research-based and published in a book. Prof Soudien, who was the guest speaker for the evening and one of the reviewers of the books nominated in this category, indicated that he found the books ‘’illuminating and in many ways challenging of positions I hold and positions that I think that we all ought to be reflecting on in terms of where our world is going’’. 

From the four nominees vying for this award, Prof Helene Strauss was announced as the winner of the 2022 UFS Book Prize for her book entitled, ‘Wayward Feeling: Audio-Visual Culture and Aesthetic Activism in Post-Rainbow South Africa’. Strauss expressed her appreciation, saying, ‘’It is a great honour to be awarded the UFS Book Prize given the high calibre of this year's nominees. It is a lovely morale boost at this time of the year when our motivation can start to flag under the weight of the workload. It inspires me to continue to try to live up to the many examples of outstanding research produced on this campus.’’ The prize includes a certificate of honour as well as a monetary award. 

The significance of the awards ceremony

While the award ceremony aims to recognise and celebrate research outputs by the UFS staff, Prof Petersen emphasises that it is also an acknowledgement of the researchers’ impact. Through their contributions, they elevate the research profile of the institution, thereby bringing the vision of becoming a research-led university, as outlined in Vision 130, closer to reality.

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.
