The Faculty of Economic and Management Sciences invites all its academic departments to participate in the 2021 celebration of Nelson Mandela Day by requesting their staff and students to become involved in a 67-minute fitness challenge to be held over a seven-day period, commencing on 18 July 2021. These kilometres can be completed by running, walking, swimming or on a bicycle (no vehicles permitted). 

These activities may be completed at any location, at any time from 18 to 25 July 2021 (terminating at midnight on 25 July). This ensures that social distancing protocols are adhered to, since each individual is completing the challenge on their own.

Participants will be required to provide relevant proof of the distance completed, as well as the date and time interval, by either submitting a picture of the treadmill screen, sharing the progress they logged by using a mobile app such as Strata, pictures of the number of steps completed, etc. (Send this via email to Reabetswe Parkies at Parkiesrg@ufs.ac.za upon completion – at the latest by 08:00 on 26 July 2021.)

Raising funds

To raise funds, each department in the faculty is requested to consider sponsoring a specific amount per kilometre completed by their staff and students. It is recommended that each department consider its available budget for this purpose and that the total departmental contribution should be capped at a specific amount to ensure that departments are not faced with open-ended liabilities.  We have sought and obtained approval from the Department of Finance for the use of UFS funds in this manner. To this end, for example, the School of Accountancy has pledged to contribute R10 per kilometre completed, capped at a maximum contribution of R6 700.

To encourage healthy competition and to increase the amount raised, departments will be encouraged to compete against each other and attempt to complete the most kilometres. Each department will donate their pledges to the charity of their choice.  In support of this noble cause, the Dean’s office has pledged a donation of R6 700 to the winning academic department, to be added to the department’s donation to the charity. 

We believe this is a very good marketing initiative, as well as an opportunity for the faculty to illustrate its commitment to social investment and community engagement.  It is also likely to contribute to improving the morale of the staff in the faculty. The UFS Community Engagement office has further indicated that it would like to arrange a radio interview to promote this event – to this end, we can raise awareness and place the spotlight on a worthy cause.

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.
