Dr Jonas Thinane graduated with a PhD from the University of South Africa.
Dr Jonas Thinane, who recently obtained his PhD in Theology from the University of South Africa (Unisa), has been working in the Department of Hebrew since his first year as a Theology student; he is currently employed as departmental administrator in the department. 

It was his diligence and comments that convinced Prof Cynthia Miller-Naude to offer him employment as student assistant in the department.  His work involves overseeing the administration of three entwined units within the department.  “I am really proud of all that he has accomplished since then, seizing every opportunity available for learning and growing, without allowing obstacles to block his path,” said Prof Miller-Naude. 

His PhD focused on Human rights abuse by some self-styled spiritual leaders within the ‘Nyaope religion’ in South Africa and was supervised by Prof MS Kgatle from the Department of Christian Spirituality, Church History and Missiology at Unisa. 

An avid academic and researcher 

Apart from the research he undertook to complete his PhD in less than two years, he published nine accredited articles and a chapter in a book between 2021 and 2022. “I currently have six articles undergoing peer review and am working on more to publish in local and international journals this year,” says Dr Thinane. 

Dr Thinane’s research specialisation lies within Missiology, where he has introduced new knowledge to the subject matter through extensive writing on concepts of missio hominum (mission of human beings) in relation to the broader setting of the Missio Dei (Mission of God). “Beyond this, some of my published articles cover broad yet relevant topics such as COVID-19 and vaccine challenges in South Africa, the question of mandatory vaccination from a religious perspective, the ANC step-aside rule in conflict with Thuma Mina objectives, and many other topics relevant to our current challenges in South Africa,” Dr Thinane says. 

“I am sure that he will make a great contribution to academia for the benefit of society in the future,” says Prof Miller-Naude. 

Support and motivation from department 

Dr Thinane is very appreciative of the support he received from the department throughout his PhD journey. 
This is indeed a great achievement within the scope of the UFS’ encouragement for publication on subjects that greatly contribute to the cognition and advancement of our society.

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.
