Staff, students and other stakeholders of the University of the Free State (UFS) can look forward to a virtual music show honouring the values and beliefs of former President Nelson Mandela. Musicians such as Simple Stories, Sibongile Mngoma, Boitumelo Mohutsioa, and Lucy Sehloho have prepared performances that will be showcased on UFS communication platforms on 31 July. Concluding Mandela Month celebrations, the pre-recorded show will also feature performances by poets Braithan Moratwa and Zilungile Muqayi. The show is coordinated by the Division of Student Affairs at the UFS.  

Angelo Mockie, Senior Officer: Arts, Culture and Dialogue at Student Affairs, says the show was primarily produced to convey a message of hope, solidarity, and support to the UFS community. “We chose Mandela Month to publish it, because those are the values that he believed in. Now more than ever, we need to stand together as a community to find ways of adapting to the new normal.”

In a message to UFS staff acknowledging the life and legacy of Nelson Mandela, Prof Francis Petersen, Rector and Vice-Chancellor, said Madiba’s example of compassion and courage made him one of the best-known leaders in the world.
“His life was a true inspiration and his devotion to democracy, equality, learning, and caring for others have earned him the respect of communities around the world.

This year, the significance of Mandela Day will be even more important than ever before, as we demonstrate caring by looking after ourselves, our families, and those around us, while we navigate through the pandemic. Caring provides purpose, but also the motivation to fulfil that purpose. The COVID-19 pandemic should enable us to imagine a world that is fairer, safer, more stable, secure, and one that can prosper.”

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.
