Qwaqwa Campus vaccination drive

As the University of the Free State is encouraging staff and students to be vaccinated in order for all of us to return to campus life as we know it, the Qwaqwa Campus held its first in-person vaccination activation drive for its first and returning students. The drive was to further encourage students to vaccinate, and to keep themselves and others safe by educating themselves.

The cheerful and excited crowd of more than 100 students were gathered at the Amphitheatre on campus, where they got to know more about the COVID-19 Regulations and Required Vaccination Policy and interacted with Department of Health officials to understand more about the jabs and booster shots.

No one is forced, but everyone is encouraged

The university’s approved policy came into effect on 14 February, requiring staff and students to be vaccinated as a measure towards ensuring everyone’s smooth return to its three campuses. However, as Qwaqwa Campus Principal Dr Martin Mandew highlighted, “no one is being forced to vaccinate, but we are all strongly encouraged to do so”.

Dr Mandew said the student experience is too rich and vibrant to be confined to virtual learning. He showed students his own vaccination certificate, quoting a Zulu proverb, ‘indlela ibuzwa kwabaphambili’, which loosely translated means ‘those who have gone before you can show the way’.

“If you are not vaccinated, it will be impossible for us to enjoy face-to-face interaction again. Ask yourself: ‘If the principal is vaccinated, who am I not to be?” he said.

The lively drive also kept students entertained through live performances by local artists. 

Students could also raise pressing issues and questions with Department of Health officials – including common side effects, apathy against vaccination due to religious beliefs, the efficacy of the vaccine to protect against COVID-19, and the implementation of the UFS Vaccination Policy. 

The programme line-up also included messages of support from the Director: Student Affairs, Zoleka Dotwana, the Deputy Director of Housing and Residences, Zakhele Mdluli, and UVPERSU Vice-Chairperson, Dr Grey Magaiza.

The operating days of the on-campus vaccination site have been extended to accommodate streams of incoming students who still want to be vaccinated.

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.
