ISRC President Simphiwe Dube.

The president of the ISRC, Simphiwe Dube, left his seat alongside the Convocation and traded his procession regalia for the black gown, as he walked across the stage to receive his qualification during the morning session of the Qwaqwa Campus graduation ceremony on 30 April 2022.

Students, proud parents, and loved ones in the Rolihlahla Mandela Hall ululated and clapped as Dube received his Bachelor of Education degree majoring in Intermediate Phase Teaching, with distinction.

Dube himself revelled in the moment, shouting “amandla” to the overjoyed crowd.

Reflecting on how he managed to balance an impeccable academic record while being fully active in student politics as well as other extracurricular activities on campus, Dube said it was all doable with determination, courage, and selflessness.

“I always knew I wanted to make a difference in one way or another, and I suppose that's why I chose teaching as a profession. Coming to university, I was received by a cloud of activism that changed the way I viewed the world. I suppose that's where my journey in the space began.” 

He said the first duty of a revolutionary was to be educated. “Education should be the bloodline of every true revolutionary; it should be the driving force, and it really is inspirational to end an academic period in a cloud of glory; this itself should be a message.”

Describing himself as keen and goal-driven through academic excellence and leadership skills, Dube shared the following words with the student community: “The true goal is to be educated; the main thing is to get that qualification. We are born to be great from the day we enter the UFS gates, we can only stop at the top. Therefore, we should always anchor ourselves in the true revolutionaries who have sought to emancipate education at every turn.”

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.
