For Prof Anthea van Jaarsveld, the balance between science, theoretical and practical experience is important for a balanced industry.
Her unique approach to Drama and Theatre Arts makes Prof Anthea van Jaarsveld the most suitable person to take over the reins as Head of the UFS Department of Drama and Theatre Arts. Prof Van Jaarsveld was officially appointed as head of this special department this year. 

The Department of Drama at the UFS is one of the biggest in the country, and according to Prof Van Jaarsveld it is also the best, because the department produces some of the finest in the industry. Her main goal as head of department is to bring about a subtle change in emphasis that will ultimately make a real contribution to employability, a greater variety of job opportunities, and practice-orientated research. “My ultimate goal is therefore an approach within which academy and practice will find each other for the benefit of both,” says Prof Van Jaarsveld.

Science, theatre and drama collide 

Prof Van Jaarsveld has a scientific approach to drama and theatre arts. She never acted professionally. It is precisely from a scientific perspective that her knowledge of the theorising and contextualisation of drama text, theatre concepts, and the film industry is applied in order to maintain a balance in a profession where the emphasis on practical experience is overwhelming.  

She studied Drama at the UFS and was also employed as Drama teacher at Eunice Girls’ School. Following this, she started working as lecturer in the Department of Afrikaans and Dutch. “There I focused on the Drama genre in Afrikaans; therefore, I never actually left drama and theatre,” says Prof Van Jaarsveld. In 2018, she returned to the Department of Drama. 

Upon her return to the department where she started her studies, her aim is to ensure that the department again complies with the total package of the UFS and to make sure “that our students are prepared for a multifaceted and dynamic industry on a practical level”. 

Prof Van Jaarsveld took over from Prof Nico Luwes who retired in 2019.

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.
