Dr Thandi Gumede
Dr Thandi Gumede graduated with a PhD in Polymer Science. She is from Intabazwe, Harrismith.
The Qwaqwa Campus of the University of the Free State was a hive of activity on 17 and 18 May 2019, when over 800 degrees, diplomas, and certificates were conferred on deserving achievers. These included six PhDs and 14 master’s degrees across the four faculties.

Congratulating the graduates on both days, was Africa’s youngest PhD and Industrial Psychology lecturer, Dr Musawenkosi Saurombe, and Prof Francis Petersen, Rector and Vice-Chancellor.

Be like heat

Dr Saurombe started her address by relating her school journey that saw her starting Grade 1 at age 5, thus later matriculating at the age of 15, having skipped Grades 3 and 10. She went on to emphasise the importance of building an honourable character.

“As a graduate, you will soon realise that your degree is useless if you do not have character,” she said to an attentive audience that continued to marvel at her remarkable school history. She encouraged graduates to be like heat that cannot be seen but can only be felt. “Noise can often be seen and heard, but it cannot be felt. However, while heat cannot always be seen, it is always felt. Be like heat and may your presence always be felt,” she said.

Do not focus on yourself

Prof Francis Petersen also encouraged graduates to look beyond their degrees by developing a set of critical values.
 
“For us as the university, this ceremony is not just about your degrees. It is about the values that you must live by,” he said. “As a graduate of the UFS, do not just believe what you are told. Ask questions and engage critically. Secondly, do not just focus on yourself. Remember that you are part of a community and it is your responsibility to make our world a better place for others. You need to be socially responsive to the needs of your community. Thirdly, remember that integrity plays a very important role. This will determine how others value you,” he said.

The two ceremonies also saw three current SRC members graduating. They are Lebohang Miya (BEd FET – Accounting and Business Studies), Duduzile Mhlongo (BA – Geography and isiZulu), and Mhlongo Sinemfundo (BA – Geography and isiZulu).

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.
