The Kovsie ACT programme encourages the evolution of UFS students to form internationally competitive graduates who embody sustainable energy knowledge and skills to contribute to the development of the global environment.

Be a part of the evolution and livestream this year’s University of the Free State (UFS) Kovsie ACT Eco-vehicle race on 15 May 2021.

What’s in it for you? Get exposed to an informative but exciting event that will assess the technology and logic behind sustainable energy sources and how this will influence the future global society.

According to Karen Scheepers, Head of the University of the Free State (UFS) Kovsie Act office, the quest for sustainable resources remains one of the top-five challenges facing the global population of today. This challenge – together with issues pertaining to food insecurity, water, waste and toxins, and the widening gap between rich and poor – poses new questions to the kind of graduates that universities produce, she added.  She further highlighted the importance of innovative critical thinking that responds to day-to-day issues experienced by society in a global context.

Therefore, the UFS has initiated an eco-vehicle project to help students develop the necessary graduate attributes to specifically address issues of sustainable resources. The aim of the eco-vehicle project is to implement, within the context of a higher education institution, a new innovative skills development solution to the challenge of sustainable resources, and to evaluate the efficacy and impact of this programme in a rigorous way. 

Through this programme, senior undergraduate students worked together in teams through a mediated learning programme to build scale-model electric vehicles and mini solar charging stations – powered by solar energy (or batteries charged through solar energy).  This experience will steer them towards finding solutions and creating awareness around 21st century issues, and adapting to the development of technology and globalisation, essentially producing an interdisciplinary experience for UFS students.

Kovsie ACT eco-vehicle skills programme

According to the Kovsie ACT team, the eco-vehicle skills programme helps students understand how their decisions and actions affect the environment, and further implores them to build on their knowledge and skills in order to address and combat complex environmental issues, while taking sufficient action to maintain its healthy state and secure it for the future. 

The skills development programme culminates in a race-day event where sustainable energy skills are put to the test. 
A certificate endorsed by the UFS and donor partner merSETA will be issued to students who have participated and who have been successfully trained and developed in the eco-vehicle skills programme, giving them a head start to the working world.

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.
