With the most gruelling year recorded in our entire lives, gradually coming to an end we remain hopeful and thankful that we have made it through. From the unexpected shock of going into lockdown, to the worry of having to use a blended approach to succeed in your academics and now finally settling into a new normal, we at the advising office bestow upon you the title of Kovsie champion…because that's exactly what you are!

One of our many champions, Carli Kleynhans, a 3rd (final) year student enrolled for BA Psychology and English shares how she survived…no, actually how she has thrived in 2020. 

• What was your biggest concern about your academics when you found out the country was going into lockdown?

My biggest concern about my academics as a final year student was whether the online learning and tests would provide the same in depth learning experiences that are necessary to build upon for future studies.

• What are some of the challenges you've experienced along the way?

Staying focused and trying not to procrastinate was a big challenge I had to conquer, especially trying to not be distracted by my family and my phone. How I survived and was able to thrive in 2020!

• What are some of the strategies you've used to ensure your academics don’t suffer? 

Time management was one of the most important strategies that I applied. For most of my classes, I was able to focus each week on a different module, by working and studying in advance I was able to keep up with my workload and still have the weekends to focus on myself, therefore creating designated time to work, study and also time to relax and read. 

• What support have you received from the institution that's helped you thus far? 
Most of my lecturers have provided needed support regarding our academics. The institution helped provide clarity with everything that was going on. 

• What do you think the UFS could have done differently to support student success? 
I think the UFS could have provided more resources for the final year students, especially considering we have to apply for further studies; online it was difficult to discern exactly what was necessary for the applications, whereas in class I feel more information would have been provided. 

• What has kept you motivated? 

Knowing it is my final year has helped to motivate me, as I have to use these grades to apply for further studies. I recently received recognition from Golden Key and this helped to further inspire me to work even harder at my academics.

• What advice do you have for your fellow Kovsies who are finding it difficult to keep going? 
Remember to make time for yourself, to look after yourself and your mental health, especially in these difficult times. Work in advance and keep to your personal academic calendar.

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.
