Kopano Melesi
Kopano Melesi has been involved with teams such as the USSA U21, South African U20 and U23 sides, and works at the Mahd Sports Academy in Saudi Arabia.

They were ambitious students, in the same study group, and graduated together at the UFS. Only a few years later, three friends from the class of 2015 are in charge of the strength and conditioning of three top sports teams in South Africa.

The former classmates Bongani Tim Qumbu (Springboks), Kopano Melesi (Bafana Bafana), and Tumi Masekela (Proteas men’s cricket) are making sure the best in the country is in shape to compete internationally.

And the trio are not the only sport scientists from their class to excel. Others like Obakeng Molopyane, who did Wayde van Niekerk’s conditioning, are also part of this special group. It all started while doing their honours in Human Movement Science and being mentored by some of the best in the business, like Prof Derik Coetzee, who was the conditioning coach when the Boks won the 2007 World Cup.

Melesi says Prof Coetzee played a big role in their development as they had a good road map to follow. “He exposed us to things in the professional world that a normal student could only dream of. We worked with national teams, domestic and international professional teams.”

“When we went out there, we were not unsure about our abilities and capabilities to execute.” According to Masekela, they were keen students and had great UFS lecturers.

“We would meet up most afternoons after lectures to break down the lesson that we had until we understood exactly what the lesson was about.”

“This included digging into the history of how certain theories came about, then debating on our own thoughts on the topic,” he says.

All three gained experience while still studying. Qumbu worked with the Kovsie Young Guns and Irawas, Melesi with the Kovsie soccer team, and Masekela with the UFS cricket team.

Melesi says early exposure, through ‘volunteering’ at local teams, is key if you want to reach the top.

“I would advise aspiring students to engage with their lecturers as much as possible in class, as they have a lot of practical knowledge about sport science that you will not read in a book,” says Masekela.

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.
