Prof Francis Petersen speech
“We can create an institution that operates and lives in the times of embracing and celebrating diversity, inclusivity, and academic excellence by ensuring that students own their time at university,” said Prof Francis Petersen.

25 January 2019 marked the official welcoming of the University of the Free State’s (UFS) first-year students, as they moved into their respective residences and were warmly welcomed on the UFS Bloemfontein Campus. This day also marked the start of the registration process for first-year students.

According to first-year Psychology student Keisha Claasen, who moved into her residence earlier on 25 January, her first experience of the UFS was daunting but exciting, as she had never been in a similar environment. According to Given Gwerera, who dropped his son off at the Karee residence earlier the day, “the UFS is an institution with great culture and an overall good academic record.” He further explained that he trusts his son to make full use of the opportunities presented to him, as he has a cool head on his shoulders.

On the evening of 25 January, an eager group of millennials, joined by their parents, took the first sip from their cup of varsity life as they assembled on the Red Square of the Bloemfontein Campus to meet the Rector and Vice-Chancellor, Prof Francis Petersen, members of Rectorate, the deans of all faculties, and the Student Representative Council (SRC) of the UFS.

“2019 will be a year of continued change; the UFS is thrilled about the prospect of bringing about opportunities for adaptation and realignment to the future,” said Prof Francis Petersen.

He further explained that the university prides itself in moulding its students into well-rounded individuals who will develop into globally competitive graduates as required in a diversity of landscapes. Prof Petersen urged first-years to remain open to the technological developments that go with globalisation, because of its permanent effects on society today.

First-years were further advised to take advantage of the rich pool of academic research and knowledge that is characteristic of the university and is piloted by UFS scholars, by engaging with and learning from them.

The inspiring night concluded on a colourful note, as the audience enjoyed an artistic laser show in front of the Main Building. Caption:

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.
