UFS Debate Society to compete in upcoming World Championships
The UFS Debate Society is a diverse, cross-boundary team of UFS students who are not strangers to success, and who are exceptionally brilliant at what they do. Before winning the largest open debating competition in Africa in 2018, the team had qualified and competed in the finals for three consecutive years since 2015. The society has now been selected to compete in the Cape Town Open Debating Competition this coming weekend from 27 to 29 April, in a build-up to the World Championships taking place in December 2018.

According to the UFS Debate Society Chairperson, Tshiamo Malatji: “Thinking artistically about debating requires one to make use of creative reasoning, and essentially, lateral thinking is of importance, even in your everyday life conversations, because you will never fundamentally agree with someone who has opinions which are opposed to yours, but you will be able to appreciate where they are coming from.”

The team is also involved in organising dialogues on our Bloemfontein Campus, such as the Student Rights Dialogue, which brings together various stakeholders of the university for a discussion about human rights. They also conduct debating workshops and, together with the Department of Basic Education, function as judges for debates in the broader Bloemfontein community for less advantaged schools in Botshabelo, Thaba Nchu, Tweespruit, and Dewetsdorp.

The Debate Society is set to host a Global Politics Seminar that will analyse and explain the forces that influence international politics, and South Africa's standpoint in the global perspective. This seminar, taking place in October, will focus on the activities of chief global actors, and some of the core crises that can shape students’ understanding of current foreign affairs. The seminar will comprise presentations from knowledgeable local students and Debate Society alumni, which will conclude with a fiery debate by the society on the dynamic and controversial topic of South Africa's future in the international political arena. 

Access to the seminar is reserved for donors who will pledge their support to the society’s journey to the upcoming World Championships. For more information on how to pledge, visit the World Championships Pledge.

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.
