Prof Hendri Kroukamp, Dean of the Faculty of Management Sciences quoted the Cat Stevens song I can’t keep it in, to capture the excitement surrounding the opening of a Digital Storytelling Lab on the Bloemfontein Campus on 10 May 2019.

After months of hard work by Dr Deidre van Rooyen, Willem Ellis, Karen Venter, as well as the staff of the University of the Free State’s (UFS) Centre for Development Support, the Common Good First lab was completed just in time for the launch attended by about 50 delegates from other South African universities, as well as private and public institutions.

Stories meet technology

In a message, from Prof Puleng LenkaBula, Vice-Rector: Institutional Change, Student Affairs, and Community Engagement, informed the audience that the launch heralded the joining of the old world of stories with the new world of digital technology. Julie Adair, Director of Digital Collaboration at Glasgow Caledonian University, Scotland, welcomed the UFS as a partner to this international social innovation collaborative project in a video message. 

Dr Van Rooyen, the project manager for the UFS, explained how she got involved in the Common Good First project, what the benefits of digital storytelling are, as well as what opportunities the lab creates for cooperation between role players involved in social innovation projects. 

Why the Common Good First lab?

The purpose of the lab is to create a digital network to identify, showcase and connect social innovation projects in South Africa to one another and to universities around the world for research, student engagement and learning and teaching. The lab has been fitted with state-of-the-art equipment for recording and digitising the stories that result from social innovation projects.

In a live Skype session with Dr Il-Haam Petersen, Postdoctoral Research Fellow at the Human Sciences Research Council (HSRC), and some of the recent successes of the digital stories in Philippi in the Western Cape were shared.

Bishop Billyboy Ramahlele, UFS Director Community Engagement did the final honours by cutting the ribbon, declaring the lab open, and sharing the dream that the work done in this lab will contribute to positive relationships and cooperation between the university and the community, in making not only the university, but the country and the world a better place.

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.
