Zane Dippenaar
Dr Zané Dippenaar (30) is the youngest PhD graduate in this year’s Business Management class from the University of the Free State.

Zané Dippenaar, a 30-year-old marketing and project manager at a Cape Town-based solar energy company, is the youngest person in this year’s graduating class to earn a Doctor of Philosophy (PhD) in Business Management degree from the University of the Free State this year.  

But despite this achievement, the newly minted Dr Dippenaar says she would not have predicted she would study her way to PhD level. 

“I wasn’t particularly academically driven before tertiary education, but I knew from early on that I wanted to either become a teacher or pursue something in the world of business,” she says. Her natural ability and her family’s encouragement led her to explore entrepreneurship and marketing, which she soon developed a passion for.

 

Overcoming challenges and finding support

Dr Dippenaar’s academic journey was marked by significant challenges, including balancing work and study commitments. However, she credits her supervisors and family for helping her stay motivated. 

Her dissertation, titled ‘Advertising and Brand Loyalty in the South African Solar Industry’, showcases her expertise in marketing and branding.

“There were moments filled with doubt, setbacks, and exhaustion, but I was fortunate to have a strong support system who continuously encouraged me and reminded me of what I was working towards,” she says.

 

Achieving a personal milestone

Dr Dippenaar’s PhD achievement is not only an academic milestone but also a personal triumph. She had set a goal of completing her PhD before turning 30 and achieved it just weeks before her birthday. “That was a personal milestone I had set for myself, and achieving it was incredibly fulfilling,” she says. 

She plans to apply the knowledge she gained in the industry and potentially return to academia. She advises younger students to trust their instincts and start their academic journey without waiting for perfection.

“Don’t wait until you’re ‘ready’ – you never will be. Just start. Surround yourself with people who believe in you, ask for help when you need it, and take it one chapter at a time,” she advises.

 

A role model for others

Dr Dippenaar hopes to inspire others, particularly young women, by showing that success in academia doesn’t follow a one-size-fits-all formula. “I hope my story demonstrates that with the right support, determination, and a willingness to carve your own path, anything is possible.”

The University of the Free State is proud to have played a role in Dippenaar’s academic journey, fostering her growth and expertise in business management. Her achievement is a testament to the institution’s commitment to academic excellence and innovation.

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.
