Prof Maryke Labuschagne, a successful scientist who is doing great work to enhance food security on the African continent, admires women who have made an impact, often in male-dominated environments.

Maryke Labuschagne, Professor in Plant Breeding at the University of the Free State (UFS), is known to many for her work to enhance food security. 

She holds the National Research Foundation’s South African Research Chairs Initiative (SARChI) Chair on Disease Resistance and Quality in Field Crops, travelling all over Africa to do research on the genetic improvement of staple food crops in communities. Through decades of research and collaboration, she has also contributed to the establishment of a strong network of researchers on the continent.

During an interview in celebration of Women’s Month, Prof Labuschagne talks about her experiences as a young scientist and how she believes young female researchers should be supported and nurtured. 

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

Besides the scientists she had the opportunity to work with in countries such as Zimbabwe, Zambia, Uganda, Ghana, Ethiopia, Kenya, Lesotho, Eswatini, Tunisia, and Ethiopia, she also met women who are working the fields to produce crops for their families, raising their children, and living in difficult conditions. “These women, who make it work against all odds, inspire me,” says Prof Labuschagne.

Other women she admires and who have made an impact – often in male-dominated environments – include role models from the past, such as former UK prime minister, Margaret Thatcher; physicist Marie Curie, who was far ahead of her time; and American geneticist Barbara McClintock, who won a Nobel Prize in 1983. 

What is your response to current challenges faced by women and available platforms for women development?
 
“When I started working in the Faculty of Natural and Agricultural Sciences at the UFS in 1989, it was a different world. It was a totally (white) male-dominated environment. The number of women scientists could be counted on the fingers of one hand, and they were often not given the same opportunities as their male counterparts,” she recalls.

Prof Labuschagne continues: “With women having so many opportunities today, it is now totally different.”

She believes women will always have a double burden – being responsible for a family and having to compete on an equal footing with male colleagues in the workplace. There are now, however, many platforms and support systems specifically for women, and she encourages women to make use of every available form of assistance they can get.

I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy. – Prof Maryke Labuschagne
 
What advice would you give to the 15-year-old you?

“I would say you can have it all. Work hard, believe in yourself, follow your dreams, focus on your goals, see the opportunities – not the challenges, and leave a legacy.”

She is convinced that young women can have a family and a career, even if they believe it is not possible. 
 
What would you say makes women of quality, impact, and care?
 
“I see many women at the UFS making their mark, making an impact in their chosen fields.”

According to Prof Labuschagne, what would have been unthinkable just a few decades ago, such as women serving as deans and in top management positions, is now a reality. 

“I see young female researchers boldly taking on the world, believing in themselves and their abilities, and knowing they will be successful.” She states that each of these women should be supported and nurtured, as they will have a huge influence on the course of the university’s future.

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.
