The arts are one of the most important building blocks of any country or organisation, and it is also an important aspect at the University of the Free State (UFS). Therefore, the partnership between these two Free State institutions is important for the promotion of the arts in the province.

The Vrystaat Arts Festival is taking place on the Bloemfontein Campus of the UFS from 1 to 7 July 2019. Various UFS departments are involved in the programme, as well as in the technical and artistic planning of the festival.

UFS Drama and Theatre Arts make big contribution 

“I was involved in the planning committee and as artistic selector from the beginning of the festival, and in recent years also as member of the festival board,” says Prof Nico Luwes, Head of the Department of Drama and Theatre Arts. 

This department makes almost the biggest contribution to the festival, with various plays, such as The Island, which is directed by award-winning theatre maestro Jerry Mofokeng and Charl Henning, and two former students, Michelle Joubert and Jane Mamotse Mpholo in the cast, as well as technical assistance from staff and students. “Without the expertise of Thys Heydenrych as technical organiser and Brandon Hewitson as technical manager, the festival would not be possible,” says Prof Luwes. 

“Our theatres are world-class, and the work of our students as technical and theatre personnel is described as outstanding by all theatre artists.”


Thought-Leader Series, Sol Plaatje lecture, and several book conversations

Since 2018, the UFS has also been involved in the annual UFS Thought-Leader Series, which was launched by Prof Francis Petersen, the UFS Rector and Vice-Chancellor. The panel discussions deal with contemporary issues; this year’s topic is Economic Growth and Entrepreneurship for a Growing South Africa. The UFS will also present the Sol Plaatje lecture, which will be delivered by Diana Ferrus. Prof Petersen will also be part of a panel discussion with Prof Adam Habib, Vice-Chancellor of the University of the Witwatersrand, and Wandile Ngcaweni, about #FeesMustFall; the discussion will be facilitated by Ruda Landman.

The book by Prof Jan Coetzee of the Department of Sociology and Dr Asta Rau, from the Centre for Health Systems Research and Research, Narrating the Everyday, will also be discussed during the festival. So also, the book by Charl-Pierre Naude, research fellow in the Department of Afrikaans and Dutch, German and French, Die ongelooflike onskuld van Dirkie Verwey.

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.
