The National Student Entrepreneurship Week (#SEW2020) is a project of Entrepreneurship Development in Higher Education (EDHE) in collaboration with Universities South Africa (USAf). 

The University of the Free State (UFS) has been selected to host the National Student Entrepreneurship Week from 2 to 4 November 2020. The programme is presented virtually and will be streamed by the UFS from 2 to 4 November; the events can be accessed live on the Whova app and on Facebook: @EDHEStudententrepreneurship, allowing students to watch at their convenience.

Background of SEW 2020

The National Student Entrepreneurship Week was piloted in 2017 and successfully executed in 2018 by the public universities and TVET colleges. This year, themed #AfroTech, #SEW2020 aims to gain participation from all (26) public universities and TVET colleges.

Objectives of SEW 2020

The objectives of Student Entrepreneurship Week are to raise awareness among students that participation in the economy is not necessarily only through the avenue of formal employment. Students are encouraged to develop innovative and creative ideas to solve many problems facing society. This year, the event allows universities and TVET colleges to showcase the different entrepreneurial activities and achievements of their institutions, which are intended to raise awareness and inspire students towards entrepreneurship and emphasising the benefits of having the best of both worlds as a student and as an entrepreneur.

Format of event

The event promises to offer a high-impact experience that will be easily accessible virtually, with multi-institutional participation and collaboration nationally. Participating universities will contribute to the content of the programme, which will be curated by the EDHE and livestreamed by the EDHE production partner.

The virtual format of the event allows students to preselect sessions in order to create a personalised experience that is customised for their personal schedules and circumstances. Students can watch the live stream as well as missed sessions on YouTube, and further engage with their own institution or with EDHE on social media.

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.
