Mr Nikile Ntsababa took up the position of Registrar at the University of the Free State (UFS) on 1 May 2019. His appointment was approved by the UFS Council during its quarterly meeting on 15 March 2019.
 
“Mr Ntsababa is an experienced and knowledgeable university registrar with 10 years of senior management experience in institutional compliance, regulatory compliance, academic administration, and university records management. His history of senior roles in the higher-education sector has the advantage of a very good understanding regarding the dynamics, context, and challenges that the position of registrar brings,” says Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.
 
He holds a Postgraduate Diploma in Records and Archives Management from the University of Fort Hare, a Master of Public Administration from Nelson Mandela University, and a Bachelor of Arts in Communication from the University of Fort Hare. Some of the further certification and short courses he has completed includes a Certificate in International Higher Education Management from Vanderbilt University, Tennessee State in the USA, and a Compliance Management Certificate from the University of Cape Town. He is a Certified Ethics Officer.
 
Mr Ntsababa was Registrar at the Cape Peninsula University of Technology (CPUT) from April 2012 to April 2019; before that he was Deputy Registrar at CPUT from April 2009 to March 2012. He also served as Director of Governance at the University of Fort Hare from September 2007 to March 2009, and as Faculty Manager: Management and Commerce at the University of Fort Hare from January 2004 to August 2007.   
 
“I look forward to working at the UFS and to share my knowledge and experience of higher-education legislation and the associated regulatory processes, requirements, and trends in the higher-education sector,” says Mr Ntsababa.

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.
