Kate Poen is an Academic Adviser in the Centre for Teaching and Learning.

The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Kate Poen, Academic Adviser in the Centre for Teaching and Learning, shares her UFS journey:

 

Q: Year of graduation from the UFS:

A: April 2018 and 2023.

Q: Qualification obtained from the UFS:

A: BSocSci Honours in Psychology and PGDip in Higher Education.

Q: Date of joining the UFS as a staff member:

A: I joined the UFS as a staff member in 2017.

Q: Initial job title and current job title:

A: My initial job was as a Teaching Assistant for UFS101 (now UFSS) under Transition Development and Success (TDS) and I am currently an Academic Adviser under Advising, Access, and Success (AAS) in the Centre for Teaching and Learning.

Q: How did the UFS prepare you for the professional world?

A: The UFS has taught me responsibility and accountability as a professional. It instilled in me the competence of lifelong learning, to consistently develop myself personally and professionally, as well as the ability to always innovate my skills, and not only be an individual able to compete on a national level, but globally in the higher education space as well.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member?

A: Transitioning from a UFS alumnus to a staff member has been interesting. Being a UFS alumnus in my experience opens the door to opportunities for growth and development, even with the challenges it does bring. It is a personal choice as to whether one sees and uses the opportunities. What it does provide one with is definitely an informed perspective of the staff experiences, especially support staff.

Q: Any additional comments about your experience?

A: I am grateful for the opportunities I’ve been afforded at the institution to not only grow as an individual, but also to make a difference and a little impact in the work that I do daily. Grateful for the relationships I was also able to establish with colleagues in different spaces on all three of our campuses.

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.
