Braam van Wyk, hockey high-performance manager at the University of the Free State, should gain valuable experience with the Ghana men’s hockey team.

Braam van Wyk, hockey high-performance manager at the University of the Free State (UFS), wants to plough back whatever he can at international level.

Van Wyk has been appointed as assistant coach of the Ghana men’s hockey team. It is only a part-time appointment, as they don’t play that many matches in a year. Ghana is ranked 35th in the world.  

He will assist the team in the run-up to the Africa Cup in August 2019, where they hope to perform well enough to get an opportunity to play in the Road to Tokyo qualifier for next year’s Olympic Games. 

Van Wyk currently coaches the Ghana players who are based in South Africa. 

“I see this as an opportunity to develop the players, but also for me as a coach to grow and to coach at international level. I am excited to try and add value. The plan is to implement it here at the UFS,” Van Wyk said.

He is also the head coach of the UFS men’s team since 2016, as well as the astro manager.

Learned a lot from coach dad

According to Van Wyk (32), who studied environmental management, he already started coaching in his first year of studies while he was still playing. He represented the UFS from 2006 to 2009. 

“Between 2010 and 2015, my focus shifted to umpiring and I officiated in 19 internationals of which five involved the Protea men’s team.” 

His father, also Braam, is never too far away for guidance. Braam Sr is an astute coach who stood at the helm of many teams over the years, including the Kovsie men and women. He also coached his son while he was playing for the UFS.

“While I was playing, I used to ask him a lot of questions. I learned so much from him and still approach him for advice. He has so much experience and has achieved so much.”

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.
