They came from near and far; the attendees were both from the founding and the contemporary generation – up to the current President, John Macheke. This was reflected in the guest and speaker lists of the colloquium, which was hosted by the Qwaqwa Campus Faculty of the Humanities and the TK Mopeli Library to celebrate the 40th anniversary of the Congress of South African Students (Cosas).

Acknowledging Cosas pioneers

“The two-day colloquium was aimed at enabling all Cosas generations to engage meaningfully, while highlighting the role of its leaders in the struggle for a democratic system of education and country,” said the organiser, Dr Tshepo Moloi from the Department of History.

“We must appreciate the founders of Cosas, as they have not been adequately acknowledged in the democratic dispensation. The organisation fought many battles – one of which was to enable many of us to finally register at institutions of higher learning when it was not as fashionable as it is now,” said Patrick Letsatsi from the Department of Sports, Arts and Culture (DSAC). 

Letsatsi also expressed the DSAC’s mission of facilitating such dialogues on matters of national interest. “Talking enables us to see that burning a library when we need a road is not the right way of dealing with matters,” he said.

Limited research on Cosas

On the academic research front, it is clear that minimal work has been done to reflect on the role played by Cosas over the years. “There is limited scholarly research on Cosas,” said Prof Noor Nieftagodien, the Head of the History Workshop at the University of the Witwatersrand.

“Despite this, we know for a fact that the founding members of Cosas found themselves under serious threat from the state. They were detained almost immediately after its formation in 1979, yet the organisation continued to produce leaders who not only played a pivotal role in the underground movement and formation of youth congresses and trade unions, but also in the shaping of our democratic state,” he argued.

The colloquium also featured Prof Monique Marks, who spoke at length about Cosas in the 1980s and the 1990s. There was also a presentation and photo exhibition by veteran anti-apartheid activist and former member of the Black Sash, Gille de Vlieg, whose photographs back then were inspired by the energy of the students. Other panellists were, among others, founding members Oupa Masuku, Vusi Gqoba, Super Moloi, Titi Mthenjane, and former Free State MEC, Oupa Khoabane.  

The colloquium was hosted in partnership with the national Department of Sports, Arts and Culture and the National Institute for the Humanities and Social Sciences (NIHSS).

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.
