The University of the Free State Qwaqwa Campus is celebrating a significant boost to its academic and research standing with the recent achievement of National Research Foundation (NRF) ratings by several esteemed academics. These ratings not only recognise the individual accomplishments and impact of these researchers but also underscore the campus' commitment to Vision 130 and the university's overarching strategy for academic and research excellence.

The Deputy Vice-Chancellor: Research and Internationalisation, Prof Vasu Reddy, explained the ratings, saying, “Ratings embody high ideals and recognition of scientific merit and impact in a knowledge-intensive economy, aligned with the UFS’ aspirations.”

Prof Jared McDonald, Assistant Dean of the Faculty of The Humanities, Dr Calvin Mudzingiri, Assistant Dean of the Faculty of Economic and Management Sciences, and Prof Richard Ocaya from the Department of Physics have all been awarded C2 ratings, signifying that they are established researchers with considerable international recognition for the quality and impact of their research outputs. This level of recognition highlights their consistent contribution to their respective fields and positions them as key players within the global research landscape.

Building on this impressive achievement, Prof Aliza le Roux, Assistant Dean of the Faculty of Natural and Agricultural Sciences, has attained a C1 rating, indicating that she is a leading international researcher recognised for the high quality and impact of her recent research outputs. This prestigious rating stresses Prof Le Roux's significant contributions and her standing as a prominent figure in her area of expertise.

Adding to the growing cadre of research talent on the Qwaqwa Campus, Dr Nthatisi Nyembe, Lecturer in the Department of Zoology and Entomology, and Dr Victor Gwande – Senior Lecturer in the Department of History – have both received Y1 ratings. Dr Regret Sunge, Lecturer in the Department of Economics and Finance within the Faculty of Economic and Management Sciences, has received the NRF Y2 rating for the period 1 January 2025 to 31 December 2030. This rating is awarded to promising young researchers who have demonstrated the potential to establish themselves as researchers with strong international recognition within five years after obtaining their doctorates. These Y1 ratings signal a bright future for research on the campus, highlighting the emergence of a new generation of impactful scholars.

NRF ratings are a crucial benchmark within the South African academic and research sector. They provide a peer-review assessment of the quality and impact of researchers' work, lending credibility and prestige to both the individual and their institution. For academics, a strong NRF rating can enhance their research collaborations, funding opportunities, and overall academic standing. For the institution, a growing number of rated researchers reflects a vibrant research environment and contributes to its reputation as a leading centre of knowledge production.

These achievements align directly with the UFS' Vision 130, which aims to elevate the university's academic and research profile, fostering a culture of innovation and impactful scholarship. The success of these Qwaqwa Campus academics demonstrates the tangible progress being made towards realising this vision and strengthening the university's strategic goals in academic and research excellence.

The UFS is committed to nurturing and supporting its academics in their research endeavours. Initiatives such as the Future Professoriate Programme and the Emerging Scholars Advancement Programme (ESAP) play a vital role in providing mentorship, resources, and opportunities for academics to develop their research careers and achieve their full potential. The recent NRF ratings are a testament to the effectiveness of these support structures and the dedication of the academics on the Qwaqwa Campus.

The University of the Free State proudly celebrates the accomplishments of Prof McDonald, Dr Mudzingiri, Prof Ocaya, Prof Le Roux, Dr Nyembe, Dr Gwande, and Regret Sunge. Their success is a source of inspiration for the entire university community and reaffirms the Qwaqwa Campus' growing prominence as a hub of impactful research.

In his congratulatory remarks, Prof Reddy said: “Our colleagues’ ratings confirm their dedicated and sterling work in advancing research and innovation. It is commendable to also see academic leaders in professional support being beacons to inspire others.”

He further commented: “We value your hard work and determination. Congratulations, you make us proud as a university. You inspire us all to follow you and we support you in reaching our research-intensive goals. We are confident that your ratings will inspire you, personally and professionally – as well as other colleagues – to grow further. Your efforts will help us as we move to new heights,” Prof Reddy concluded.

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.
