Tennis the bright spark at USSA
The Kovsie Tennis team was crowned as USSA victors for the eighth consecutive time at the recent University Sports South Africa tournament

Even though some Kovsie sport codes came close, it was eventually only the tennis team who were able to grab hold of a gold medal at the various USSA (University Sport South Africa) tournaments taking place in numerous cities across the country during the student winter holidays.

It was the eighth consecutive USSA crown for the Kovsie tennis team. They won all their matches with ease and even the final against Tuks was a one-way affair, winning eight games to one.

The other sport that came close to winning their tournament, was the netball girls. They came unstacked in the final, losing 30-48 to Tuks. It was the first time since 1998 that Kovsies hosted the USSA netball tournament.

The Kovsie female hockey team claimed third spot and the men, playing in the B section, ended second. They only lost once (against the University of KwaZulu-Natal by a single goal), which denied them promotion to the A section.

The Shimlas nearly obtained bronze, but a penalty try for Wits in the closing minutes cost them in the play-off match for 3rd/4th position.

Both the men and women’s football teams ended sixth, but more importantly, the women qualified for the 2019 Varsity football competition. The women improved by two positions and the men by four places from the 2017 tournament.

The table tennis team didn’t have an official final position. They lost in the quarterfinals.

The basketball men ended ninth and the women tenth, improving by ten and six places respectively.

The volleyball men’s team finished in 11th position and the women took 15th spot.

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.
