Outstanding Alumni awarded
Attending the awards evening were from the left: Dr Mafu Rakometsi; Gustav Wilson; Dr Pieter du Toit, National Executive Alumni Chairperson; Ace Moloi; Dr Khotso Mokhele; Prof Dave Lubbe; Dr Suzanne Staples; Prof Francis Petersen; Bertus Jacobs, and Tshepo Moloi.
A medical doctor, an economist, an author, and experts in the fields of Information Technology, Education, Management and Sociology are the winners of this year’s Chancellor’s Distinguished Alumni Awards. 

This is the 36th year that the UFS honours those alumni who are not only flying the Kovsie flag high, but are inspiring excellence and transforming lives.

Chancellor’s Challenge

UFS Chancellor Dr Khotso Mokhele had a sobering message for those who attended the awards ceremony on 8 September. He shared how, on a recent visit to the US, he had a chance to visit the campus of Facebook in Seattle, and heard how every year Facebook received more than two million CVs from prospective employees – 98% of whom sported A-average grades. Management then confided in him that they never hired a CV, but rather a mindset.

“They sift through all those applications, looking for someone with a vision to disrupt the status quo,” Mokhele said. “This continent will be left behind if we don’t adopt that mindset – that confidence that borders on arrogance – that we can change the world. Are we ready for that challenge?” 

The recipients in the various categories are:

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.
