A jubilant gradaute

Few moments in a student’s life are as memorable as graduation day. Graduates on the Qwaqwa Campus soaked in their moment and revelled in their accomplishments during the two-day ceremonies on 14 and 15 April 2023.

Graduations on the Qwaqwa Campus are known for their unique traditional flair, and during the two-day ceremonies, the excited graduates did not disappoint. 

One thousand seven hundred and eighty-eight qualifications were awarded during the two-day ceremonies. As they walked across the stage to receive their qualifications, graduates ululated, chanted, and whipped out various traditional and modern dancing styles to celebrate their degrees. 

Graduates reminded to leave a lasting legacy

Joining the excited graduates was Prof Adipala Ekwamu, a trailblazer in the field of agriculture who was awarded an honorary doctorate on 14 April 2023 during the Natural and Agricultural Sciences graduation ceremony on our Qwaqwa Campus, and Kopung Ralikontsane, the Director General of the Department of Cooperative Governance and Traditional Affairs in the Free State, who was a guest speaker at the Faculty of Education ceremonies on Saturday 15 April 2023.

Addressing graduates during his acceptance speech, Prof Ekwamu challenged his ‘fellow graduands’ to be drivers of change in their respective industries.

“I was very impressed by the quality of the students and graduates that this university has trained. May I remind everyone that universities have always been the drivers of development and reform? Elsewhere, and in Africa too, they have contributed to the political discourse and catalysing the rate of economic development. I appeal and call upon all universities to remain the powerful drivers of innovation and environmental protection, poverty reduction, and inclusivity in all their undertakings.”

Likewise, Ralikontsane encouraged students to get involved in building the nation beyond its current limitations. Having trained as a teacher, Ralikontsane spoke about a teacher's lasting legacy as he shared his teacher reflections and gave a congratulatory speech to the graduates.

“You now have the responsibility to help our collective endeavours as a nation to improve our education, training, and innovation. I wish you to rise above the prevailing limitations of our time, insidious poverty and underdevelopment inflicted on our people, as underpinned by the principles of Batho Pele.”

The UFS wishes to congratulate our new graduates who received qualifications in ceremonies on the Qwaqwa Campus. We would like to say – Thank you for allowing us the honour to recognise your contribution to our society.

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.
