Ronet Vrey.

She is affectionately called ‘Tannie Ronet’ by the dozens of students coming her way, and Faculty of Education librarian Ronet Vrey would not have it any other way. While Vrey loves to remain behind the scenes, her passion for students makes her a big hit with every student crossing her path at the University of the Free State Library and Information Services on the Bloemfontein Campus. 

Vrey has been a librarian for as long as she can remember; a path she says was inspired by her educator mother. But instead of standing in front of a class, she gets to invest in students' academic journeys by being a helping hand in times of need. She is a UFS alumna, having graduated in 1988 with a degree in Library and Information Sciences, specialising in Education, Library Services, and Technology. 

"I was interested in library information services because back then, we were exploring the use of computers and moving in the direction of technology. Little did we know about digitisation and curation that would follow."

In 2005, she started working as librarian for the Faculty of the Humanities, before working jointly for the Faculties of the Humanities and Education. Since 2011, she has focused solely on the Faculty of Education, serving as the link between the library and the faculty. "I am supposed to focus only on students from the first year to honours level, but because of the relationships built there, many students often choose to stay with me. When they come to me for help, I don't say no," she says.

Information literacy a lifelong skill

Vrey shares the love for her job with her fellow librarians from other faculties. In 2019, the group presented a paper on embedded librarianship at the International Conference on Information Literacy (ICIL). She said they are in the process of having their paper published. "We want to be embedded in faculties in order to make students at the UFS information literate. If we can teach students information literacy skills to help themselves, we will have lifelong learners who can develop all the time, and you would have established a community of lifelong learners," she said.

One student who has benefited from Vrey's dedication and passion for students, is Dr Norma Lehasa, who obtained her PhD in 2019 after a seven-year journey due to ill health.

Vrey known as beacon of hope

Lehasa met Vrey in 2016, and says she owes her success to the likes of Vrey. Lehasa said each year when students graduate, it is people like Vrey who are supporting them behind the scenes to reach their goals. 

"My wonderful librarian, Ronet, made me focus and never give up. She used to go the extra mile for me, even teaching me how to use the resources to search for literature myself. The outcome of me being a Doctor of Philosophy today is because of people like Ronet. People like her need to be recognised for the good work that they do," Lehasa said.
Lehasa's PhD topic was: An Adult Learning Perspective on Professional Development in the Human Resources Department of the Free State Premier.

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.
