As much as it was a conference on Germanistik (German Studies) it also highlighted the international footprint of the University of the Free State (UFS) and the important role of international and national academic collaborations. 

The German Section in the Department Afrikaans and Dutch; German and French at the UFS hosted the second conference of the Association of German Studies in Southern Africa (SAGV) and German Studies in Sub-Saharan Africa (GAS) from 15-18 April 2019 on the UFS Bloemfontein Campus. 

“We are very proud to be hosting the conference. It is an international conference with delegates from overseas who are all working in German Studies or to use the German term Germanistik,” said Dr Cilliers van den Berg, Head of the German Section at the UFS. 

Waiting room in Germanistik explored

Warteräume (waiting rooms) was the theme of the four-day conference with various research papers on the role and/or value of these waiting rooms within Germanistik. “It is the transitional areas, within Germanistik, on every conceivable level,” said Van den Berg. The conference was sponsored by the embassies of Germany, Austria and Switzerland, as well as the German Academic Exchange Service and the Goethe Institute of Johannesburg.

“When I look at the theme of the conference it is extremely exciting because it reminds me of Homi Bhabha’s Third Spaces, liminal spaces and the in-betweeners,” said Prof Heidi Hudson, Dean of the Faculty of The Humanities. 

UFS and internationalisation


“One of the concepts we actively embrace is that of internationalisation. Globally and nationally, internationalisation has become accepted as one of the critical processes advancing the core business of universities,” said Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.

The delegates who attended the conference were from countries which included, among others, Ethiopia, Burkina Faso, Italy, Kenya, Germany and Namibia as well as delegates from the universities of Stellenbosch, Pretoria, Rhodes and North-West. 

“You represent a multifaceted culture that has enriched our global academic and cultural landscape over many years: great minds like Goethe, Kafka, Beethoven, Mozart, Freud, and Einstein,” said Prof Petersen.

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.
