 UFS postgraduate welcoming
Attending the Postgraduate Welcoming were, from the left: Itumeleng Mutla, second-year master’s student; Prof Corli Witthuhn, Vice-Rector: Research, Innovation and Internationalisation; Prof Witness Mudzi, Director of the Postgraduate School; Hesma van Tonder, Chief Officer: Research Librarian; and John van Niekerk, a master’s student.

The University of the Free State prides itself on being an institution committed to excellence in postgraduate education. In 2019, the UFS boasted more than 6 900 postgraduate students enrolled for postgraduate diplomas, honours, master’s and doctoral qualifications. Of these, 77% previously enrolled at the UFS, while 23% started at the institution for the first time.

Targeting this group of students who make up 17% of the total number of degree-seeking students, the UFS Postgraduate School formally welcomed new senior students to the university on Friday 6 March. 

Postgraduate success
“It is the best time to be a senior student, and I hope it is a wonderful experience,” said Prof Corli Witthuhn, Vice-Rector: Research, Innovation and Internationalisation in her welcoming address to the more than 150 postgraduate students gathered in the Reitz Hall of the Centenary Complex. 

Giving reasons as to why Kovsie students should consider postgraduate studies, Prof Witthuhn said there are many opportunities associated with making the jump from undergraduate to postgraduate student.  

“All the data shows that postgraduate studies increase employability. It creates the opportunity to deeper engage with the field that you are interested in.”
 
The postgraduate journey 
D
r Musawenkosi Saurombe, Senior Lecturer in the Department of Industrial Psychology who became the youngest PhD holder on the African continent at age 23, was also on hand to offer advice. 

“Are you willing to see the task to completion? How badly do you want it?” she challenged postgraduate students, talking about her journey from 16-year old first-year student to 23-year-old doctoral degree holder. 

Itumeleng Mutla, who is in the second year of her master’s degree in Administration, said she found the speech by Dr Saurombe inspiring and encouraging. “I felt like a groupie and took pictures with her afterwards. We felt inspired by her story and she encouraged me in my own studies. I think I am also going to push to finish my studies earlier,” she said.

John van Niekerk, a master’s student in Education and Psychology, said Saurombe’s talk was brilliant and he would like her to give a talk to learners at Kimberley Boys High, where he is a teacher.

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.
