Mr David Noko, newly appointed Chairperson of the UFS Council.
During its third scheduled meeting for the year that took place virtually on 17 September 2021, the Council of the University of the Free State (UFS) appointed Mr David Noko as Chairperson for a term of four years, as from 1 October 2021.

Mr Noko, who was Deputy Chairperson of the Council, will take over the Chairpersonship from Dr Willem Louw, whose term will come to an end on 30 September 2021.
 
“On behalf of the Council, I congratulate Mr Noko and wish him all the best during his term of leading the Council of the UFS. With the skills and competence available in the Council, complemented by Prof Francis Petersen, Rector and Vice-Chancellor, and his team, he has access to a formidable group of individuals to support him in the execution of this very important role,” said Dr Louw during the meeting. 
 
“I am humbled and honoured for the opportunity and thank the Council for their confidence and trust in me. Since serving on the Council, I have become an ambassador of the University of the Free State, talking to many stakeholders about the institution and how much it should be supported. I am here to serve and look forward to doing so in a professional and dignified manner, together with everyone on the Council and with the leadership of the university,” said Mr Noko.
 
Mr Noko is well-known and respected internationally as a business leader. He has a National Higher Diploma in Mechanical Engineering from the Technikon Witwatersrand (now the University of Johannesburg), a Management Development Programme (MDP) Certificate from the University of the Witwatersrand, and a Postgraduate Diploma in Company Directorships from the Graduate Institute of Management and Technology. He also completed a master’s degree in Business Administration at the Heriot-Watt University and a Senior Executive Programme at the London Business School.
 
Before retiring from the corporate world in 2019, Mr Noko was the Executive Vice-President of AngloGold Ashanti, where he was responsible for the company’s global Sustainable Development and Government Relations portfolios. His career began at the General Electric Company (GEC) before moving to South African Breweries in 1987, and then to Pepsi-Cola International in 1994, where he gained extensive international exposure and global experience.
 
In 1999, Mr Noko was appointed as Chief Executive Officer (CEO) of Air Chefs (Pty) Ltd in South Africa, before joining De Beers in 2002. In 2006, he was appointed Managing Director and CEO of De Beers Consolidated Mines Limited (DBCM), and in 2010 he founded his own company, CelaCorp (Pty) Ltd. He also founded ESG Advisory (Pty) Ltd, a company providing advisory services to corporates relating to environment, social and governance matters, mostly focusing on mining companies.
 
He is a member of the Institute of Directors SA and served on the boards of Royal Bafokeng Platinum Limited, Harmony Gold (Deputy Chairman), AstraPak Ltd, and PlatiStone Holdings (Chairman). He is currently a board director of African Rainbow Minerals Ltd, Tongaat Hulett Ltd, and Aveng Moolmans (Pty) Ltd.

The Council also thanked Dr Louw for his service and for the impeccable leadership he displayed during the time he served.

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.
