Medals galore at second Varsity meeting Peter Makgato
Peter Makgato won the long jump title at the second Varsity athletics meeting in Pretoria with a winning jump of 7.56m.
The University of the Free State (UFS) had a successful second Varsity athletics meeting on Friday 23 March 2018 at the Tuks Athletics Stadium in Pretoria, dominating the long jump and middle distances. 

The 25 athletes achieved six gold and eight bronze medals. Although it’s just one more than what they earned at the first Varsity meeting at the beginning of the month, two more received gold. On 2 March 2018 the Free State students totalled four gold, six silver and three bronze medals. 

Although Yolandi Stander bagged a silver in the discus, it didn’t contribute to the Kovsies’ total. Stander competed for Tuks last year and the competition rules do not permit her to participate for another university in the following year.
 
Victories in middle distances and long jump
As was the case in the first meeting, the athletes running in the red colours of the Kovsies outsprinted the rest in the middle distances with three first places. Both Ruan Jonck (1:50.56) and Ts’epang Sello (2:10.42) defended their titles in the 800m for men and women respectively.

In the 1500m for women, Tyler Beling clocked a winning time of 04:33.48 with Lara Orrock following in third place (04:46.37). Both are just 18 years old. 

Both long-jump titles were decisive victories. Peter Makgato’s winning jump (7.56m) was 0.17m more than his closest competitor, and Maryke Brits (5.81m) won by 0.14m.

Three bronze medals were added in the field events; Nadia Meiring (47.10m) in the hammer throw) and Sefako Mokhosoa (15.29m, men) and Molebohang Pherane (11.67m, women) both in the triple jump. 

On the track Ané Erasmus (400m hurdles, 1:04.04), Hendrik Maartens (200m, 21.01) and Sokwakana Mogwasi (100m, 11.99) all ended in the third spot. 

The men’s varsity mixed medley relay won their race once again, and the men’s 4x100m relay finished third. 
The Kovsies ended fourth overall after the two meetings.

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.
