Participants in the third Amazing Race travelled through the African continent, experiencing Africa’s roots and its rich, vibrant, and diverse cultures

During the third Amazing Race presented by Organisational Development and Employee Wellness, staff had the opportunity to virtually travel through Africa. 

The aim of the race with the theme, A Journey through Africa, was to celebrate South Africa and Africa’s roots and its rich, vibrant, and diverse cultures. 

Natasha Nel, organisational development specialist and organiser of the race, says they wanted to give the 13 participating teams the opportunity to explore, learn, create, and be challenged together as they travel to some of the most interesting and exotic locations around Africa, but also in South Africa. 

Here in our own country, teams had the opportunity to experience our culture as well as the diversity of beliefs and traditions.

Interactive and exciting event

Nel says staff could join the race in the convenience of their personal working space via a Zoom meeting. “They only needed to download the game that was specifically tailored for the UFS.” 

“It was a fun, interactive, and exciting event. In this unique adventure, it was interesting to see how teams worked together, made decisions, and also thought outside the box during the challenges,” she says.

Nel explains that teams were requested to take photos, answer questions, and make decisions unique to Africa and their culture. Some decisions and answers were timed. They also had to decide where they wanted to travel, but each decision and option had its costs, reward, and challenge linked to it.

We are the champions

Chanel Lewis, Aneke Kruger, Runé van der Merwe, and Lischen du Randt walked away as winners of the third Amazing Race. 

By participating in this race, the university has sponsored 13 breakfasts for the Community Chest of South Africa (this organisation’s mission is to inspire and facilitate community giving for community enhancement).

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.
