East College - Eco Vehicles Team
Overall winners of the 2022 Eco-vehicle race, East College, hard at work to get their car ready for the race held at the Odeion parking lot on the Bloemfontein Campus.

For the first time, the University of the Free State’s 2022 Eco-vehicle race – held on the Bloemfontein Campus on 14 May 2022 – had students from all three campuses participating in the programme and race; a cup was awarded to the college with the best support.

Although the annual event did take place in 2021, only team members were allowed access to campus due to the COVID-19 pandemic and lockdown regulations, and therefore the race was streamed live. 

Karen Scheepers, Assistant Director: Student Life, said: “To have the students back on campus supporting their teams was incredible; this event will become bigger and better every year.”

With the Eco-vehicle race project, the UFS aims to use an innovative skills development approach that will enable students to develop basic knowledge and skills on sustainable energy.

This year, 130 undergraduate students enrolled for this co-curricular skills programme that runs for nine months and culminates in the Eco-vehicle race. A total of eight teams competed in the energy efficiency race, speed race, obstacle course race, and the main event – the endurance race. For the first time in the main event, the teams raced against each other for 18 laps. 

The winners of this year’s event were Central College (Akasia, Karee, Kagiso, Soetdoring, and Wag-’n-Bietjie residences) for Spirit Cup, South Campus took home the Pit Stop, North College won the Smart Lap, and South College won the Endurance Race. The overall winners of the Eco-vehicle race were East College (Legatum residence). 

The driver for East College, Lebakeng Motlotlo, said: “Even though I have always been part of the KovsieACT Committee in my residence, seeing that the focus this year was more on energy saving and saving resources, it pushed me to participate.”

Motlotlo believes the practice he and his team went through worked for them, as they were able to practise “how to turn, slow down around corners, and save energy”. 

“Our team was very dedicated and knew how to improvise when faced with challenges. As a small residence and most of us living off campus, the race taught us the importance of teamwork.” 

Motlotlo believes “initiatives such as the Eco-vehicle race are important, as we learn other skills outside of lectures, which we sometimes think are not important”.

Scheepers said the plan is to “grow the programme, motivate other universities to also invest in their students through this programme, and race to become a national and maybe an international event”.

“The programme adds value to the student experience to ensure that they do not only obtain a degree during their study period, but also undergo practical application of acquired knowledge and skills through real-life situations and meaningful learning encounters,” said Scheepers.

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.
