Assistant Deans Qwaqwa — Dr Calvin Mudzingiri, Prof Cias Tsotetsi & Prof Jared McDonald.

In a remarkable feat of academic excellence, the Qwaqwa Campus of the University of the Free State (UFS) celebrates a series of significant achievements by its esteemed academics. These accomplishments highlight the exceptional talent and dedication within the campus community.

Dr Calvin Mudzingiri, Assistant Dean: Faculty of Economic and Management Sciences, has achieved a significant milestone with the attainment of a C2 NRF rating. This prestigious recognition acknowledges his outstanding research contributions and solidifies his position as a leading scholar in his field. Dr Mudzingiri is also highly regarded for his teaching and mentoring skills. He is known for his engaging lectures, his ability to connect with students, and his dedication to their academic success.

Prof Aliza le Roux's groundbreaking achievement

Prof Le Roux, Assistant Dean: Faculty of Natural and Agricultural Sciences, made history by becoming the first woman to be appointed as a full professor on the Qwaqwa Campus. Prof Le Roux is also a respected leader and mentor, known for her guidance and support of students and colleagues. This groundbreaking achievement serves as an inspiration to aspiring female academics and further strengthens the university's commitment to gender equality. Prof Le Roux is a highly accomplished researcher with a strong track record of publications in her field.

From Assistant Dean: Faculty of Education to Vice-Principal

Prof Cias Tsotetsi's promotion from Assistant Dean: Faculty of Education to Vice-Principal is a testament to his exceptional leadership qualities and dedication to the university's mission. His expertise and guidance will undoubtedly play a crucial role in shaping the future of the Qwaqwa Campus. He brings a wealth of experience and expertise to this role, having served as Assistant Dean: Faculty of Education.

Double success for Prof McDonald

Prof Jared McDonald, Assistant Dean: The Humanities, has also achieved a remarkable double success. He was promoted to a higher academic rank – from doctor to associate professor – while simultaneously securing a C2 NRF rating. This accomplishment highlights his commitment to both teaching and research excellence.

These achievements by the assistant deans on the Qwaqwa Campus exemplify the high calibre of academics within the institution. Their dedication to research, teaching, and leadership serves as an inspiration to students and colleagues alike. The Qwaqwa Campus is proud to recognise and celebrate the outstanding contributions of these exceptional individuals.

In acknowledgment of exceptional academic prowess, the Campus Principal, Prof Prince Ngobeni, remarked, “In academia, it is not every day that we witness a blend of exceptional leadership, unyielding commitment, and a deep-rooted passion for education. I extend my sincere gratitude to our esteemed assistant deans for their unwavering commitment. The calibre of our faculties with their inquisitive minds, relentless pursuit of knowledge, and dedication to nurturing future researchers, truly defines the excellence of our university. Your contributions to both the university and the advancement of knowledge are deeply valued. Thank you for your invaluable effort,” concluded Prof Ngobeni.

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.
