Two athletes, both employees of the University of the Free State (UFS), are now giving back to the sport in administrative roles.

Kesa Molotsane and Louzanne Coetzee are making time in their work and training schedules to serve the sports in which they have represented their country – Molotsane in cross-country and Coetzee in the 1 500 m and 800 m T11 category for athletes with a disability.

Coetzee is again heading for the Paralympic Games in Tokyo. She is a nominee for the International Paralympic Committee Athletes’ Council. Six representatives will be chosen at the Paralympics.

Coetzee was recently elected to the South African Sports Confederation and Olympic Committee Athletes’ Commission. She is also an athlete representative of the South African Sports Association for Physically Disabled.

Molotsane was co-opted into the National Executive Committee of University Sport South Africa as an assessor. She is also the new vice-chairperson of the Athletics South Africa Athletes Commission.

“My biggest dream is to enable athletes to dream big, and for their dreams to be recognised. I would like to see them enjoy their sport,” said Molotsane.

“I think I probably missed a lot of opportunities in my career due to a lack of funding, so I don’t want to see anyone face the same situation.”

Molotsane was also recently named as one of two ambassadors for the SPAR Grand Prix Series. 

According to Coetzee, a former member of the Student Representative Council at the UFS, she believes that it is important for a current sportsperson to contribute and give input in their sport. 

“I enjoy leadership, it is perhaps a gift of mine. Serving the sport in that capacity is not something that is too much of an effort or takes too much of my time. I enjoy contributing and to see something move in a direction.”

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.
