Jenna Clarkson
Jenna Clarkson is a devout communications student and a karateka. She had to deal with several health challenges during her studies, but nevertheless dreams of obtaining her PhD in Communication at the UFS.

Overcoming numerous health obstacles during her studies, Jenna Clarkson is in high spirits after obtaining her degree from the University of the Free State (UFS). While most students enjoyed an active social and campus life, she often had to visit the hospital while studying. Receiving her BA Integrated Organisational Communication qualification during the April 2023 graduation ceremony has been a healing balm after many years of pain. 
 
The Faculty of the Humanities graduate was diagnosed with type 2 diabetes in 2021. In 2022, after several physiotherapists and emergency room visits, she was also diagnosed with juvenile disc disorder and sacroiliitis. The latter condition affects one or both sacroiliac joints where the lower spine and pelvis meet and may cause pain in one or both legs. 

Initially, Jenna assumed she had hurt herself during karate practice, but the pain would not subside. “I would randomly lose feeling in my legs and couldn’t sit. I spent a year in pain and struggled to walk, lift heavy objects, cough, and sleep on my side. I struggled with the fact that this was going to be an issue for the rest of my life.” 

However, with a lot of love from her friends, support from her lecturers, and grace with herself, Jenna learned how to handle the pain and to realise when she has met her limits. This student from Johannesburg says that although pain is frustrating and overwhelming, having emotional support helps. “Sometimes just having someone to listen and be there is the best thing.”

The journey to the graduation stage might have been difficult for this high-flyer, but it was a worthwhile undertaking. 

“I feel over the moon, and a little overwhelmed that it happened,” says Jenna about getting her degree in communications. Loving her field of study, she attended class eagerly and enjoyed her modules. “I love that I am allowed to create, I get to make something. There’s nothing more amazing than getting a brief and being able to look at it and create something from it that nobody else would have created. The bonus is that I am quite good at it too,” adds the student who is currently doing her honours degree at the UFS. 

Getting her first degree from the UFS, Jenna is determined to excel in her chosen field. 

“I would like to get my honours degree cum laude and do a PhD degree, but I am taking it one degree at a time. If it doesn’t work out that way, it’s okay. I am very good at figuring things out and making a plan.”

Jenna is determined to make her parents proud. “Having lost my dad at four, I do everything with the hope that he would be proud of my choices. My mom sacrificed a lot to give me the best life she could.”

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.
