Kovsie Eco vehicle parade — A highlight for first-year and senior students is the ACT eco-vehicle building and parade through the streets of Bloemfontein.

Sunny skies, cheerful faces, and an overall great atmosphere surfed the University of the Free State (UFS) Bloemfontein Campus on Saturday, 1 February 2020 for the final series of events in the Kovsie ACT 2020 line-up.

The eco-vehicle parade kick-started the activities for the day and saw various student teams displaying their personalised pit-stop ‘sculptures’ along the streets of Bloemfontein. UFS residence teams Sonverlief (Houses Sonnedou, Veritas, Madelief); Soetmarmentum (Houses Soetdoring, Marjolein, Armentum); and Beykasium (Houses Beyers Naudé, Akasia, Imperium) came in first, second, and third respectively, obtaining the highest scores out of nine teams for their pit-stop sculpture constructions.

Following the parade, there were a number of fun but competitive eco-vehicle races between the teams. This included the Drag Race, Obstacle Course Race, Formula E Race, Endurance Race, and the Slalom Course Race that took place on the Mokete Square.

In the evening, students were serenaded by artists such as Early B and Spoegwolf. They danced to performances from the latest Amapiano music sensation, Kabza de Small, and legendary deep-house music duo, Black Motion, at the Rag Farm.

Assistant Director of UFS Student Life and Director of the Kovsie ACT office, Karen Scheepers, earlier urged students to get more involved in student-life programmes such as Kovsie ACT, in order to equip themselves with a variety of skills and a fulfilling university experience.

A number of senior and first-year students who were part of the action on the UFS Bloemfontein Campus this past Saturday, can attest to Scheepers’ advice.
“I’ve been looking forward to starting university for the longest time, and I am glad that I ended up at the UFS. I don’t feel alone, I feel like I can actually do this,” said first-year Psychology student, Thulisa Shezi.

“University isn’t as bad as everyone thinks it is, it’s just a matter of staying motivated, doing your work, and surrounding yourself with the right people in the process.” – Fourth-year Business Management student, Earl van der Westhuisen.

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.
