Staying safe during the coronavirus pandemic extends to ensuring that students at the University of the Free State (UFS) are safe from crime. Crime in South Africa remains an unfortunate reality which continues to affect students, staff and the institution in general. 

“Crime requires constant vigilance from the community and this can only be achieved through initiatives that are aimed at informing the community on what to do and what not to do. To this end the BSafe Safety First flyer is geared at informing specifically the student community on safety measures that must be taken,” said Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison at Protection Services.

The Safety First flyer is a guide for students to be crime-conscious whether at their accommodation, on the street, or in their vehicles. It also offers tips on how to act responsibly as far as alcohol and drugs are concerned.

Engaging students on their safety 

UFS Protection Services recently engaged with off-campus residence students in Bloemfontein in order to provide tips on how to stay safe in their neighbourhoods. During the engagement, the new Safety First pamphlets were distributed, and students were encouraged to join the Student Crime-Stop Brandwag WhatsApp group.

As from 15 June 2020, Nissi Armed Response was deployed from 18:00 to 06:00. This initiative has already led to them responding to several suspicious persons and vehicles, as well as some minor incidents and disturbances. Two arrests were made on different occasions as a result of the deployment. In the first incident, a suspect was arrested on 27 June 2020 after a burglary in Brandwag, and the second relates to a suspect who was arrested on 10 July 2020 after threatening students at Universitas.

These successes were the result of student and community participation in providing information, coupled with excellent response from private security companies, including Nissi Armed Response, VR Security, and BloemSec.

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.
