Katleho Nkosi’s design, which won him second place in the national design competition during the Student Entrepreneurship Week 2022.

Katleho Nkosi, a fourth-year Education student at the University of the Free State (UFS), obtained second place in a national design competition hosted virtually by Entrepreneurship Development in Higher Education (EDHE). 

The national design competition formed part of the launch of the Student Entrepreneurship Week 2022, which took place at the University of Venda on 18 August 2022. As such, students from many of the universities in the country, including Nkosi, took part in designing a poster that would be used to advertise the event. 

Nkosi is delighted and excited about this accomplishment. “This win was really surprising and unbelievable for me, because obtaining the second-place position means that my work is good,” said Nkosi.

The participants were allowed to conceptualise and submit their final product between 28 June and 15 July 2022. “I had no experience in this space, I only designed content for fun, and I participated in this competition because I was motivated by a friend,” Nkosi highlighted.

The motivation behind the design

Since the Student Entrepreneurship Week was held at the University of Venda, Nkosi used the vibrancy and colourfulness of Venda as inspiration for his design. “When I was designing the poster, the only thing on my mind was making sure that I put something together that was related to Venda,” he explained. In addition, the theme for the Entrepreneurship Week was ‘Move to Market’, and Nkosi asserts that he tried to integrate the theme with Venda, and this is how the design came about.

The outcome of the competition and future plans

Although Nkosi did not win the competition, he did receive a cash prize for being among the top three. Furthermore, given his accomplishment, Nkosi would like to take part in many more design competitions moving forward. “Now that I have realised that I have the potential to win, I think I can take this as a career path in the future,” he said. Nkosi is also looking at merging his love of teaching with his newfound love for design. “I’m going to try and find the connection between design and education, because I really love to teach, so I could perhaps become a design teacher,” Nkosi expressed

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.
