Transforming the South Campus to a digitised university, Dr Maria Madiope is a resilient and strong guardian of the future generations.

Dr Maria ‘Marinkie’ Madiope, who grew up in Garankuwa Pretoria, is not your average professional woman. Her academic record speaks of vigilant style and resilient independence. Dr Madiope is currently the South Campus Principal at the University of the Free State (UFS) in Bloemfontein.

What is the best thing about your job?
It has given me the opportunity to transform the South Campus to a digitised university. I cannot express the feeling I have when welcoming students to the UFS and then presenting qualifications to them, especially to students who have gone through very traumatic home, personal, or academic times. 

What is the best and worst decisions you have ever made?
The best decision I have ever made was embracing education and making sure that I am not only certificated but learn to empower others in a very humble way. I don't want to think about my worst decisions. There's too much regret in everyone's lives to maintain our wavering joy.

What does the word woman mean to you?
It describes a proud warrior. A resilient and strong guardian of the future generations. The archetypal matriarch who is fearless and also tender, powerful but not afraid to demonstrate weakness, and self-sufficient yet dutiful. She is everything and anything, because she knows that she in control of whoever she wants to be. Her entire being is guided by this knowledge and self-love.

Which woman inspires you, and why?
My mom inspires me. She always had a smile on her face no matter how hard she worked, and she loved everyone. Her greatest strength is her ability to let nothing, and no one, remove her crown. “Strong winds may blow, but a QUEEN will bobby pin that thang in place and persevere because she is more than a conqueror.” I am also inspired by Maya Angelou’s poem Still I Rise about the struggle to overcome prejudice and injustice. It is one of Maya Angelou's most popular poems. When read by victims of wrongdoing, the poem becomes a kind of anthem, a beacon of hope for the oppressed and downtrodden.

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.
