At a gala event held on the University of the Free State (UFS) Bloemfontein Campus, on 28 September 2019, the top 14 entrants in the 39th UFS-Volksblad Matriculant of the Year competition were given an opportunity to share their vision with invited guests.

In his introductory speech, Pieter Hoogenboezem, deputy head boy of Pietersburg High School in Polokwane, Limpopo, said: “I think the Matriculant of the Year should strive to do their best in everything they attempt, and they should be good at communicating with others.” Pieter will be studying medicine at the UFS next year. He was crowned the winner of the 2019 Matriculant of the Year competition and also received the Sparkling Personality award, as decided by his fellow finalists. 

Pieter says of this achievement: “I am humbled and so blessed with the talents my heavenly Father has given me. I believe that the training and knowledge that I will receive at the UFS will empower me to make a worthwhile contribution to the medical field and society at large. It is going to be a great privilege for me to make Kovsies proud and to move others to become part of this university that promotes transformation, diversity, and inclusivity!”

Several other prizes were also awarded during the evening. Mandie de Wet from the Hoër Meisieskool Oranje in Bloemfontein walked away with the prize for best achievement in sport for her prowess on the hockey field, and Runé Edeling (Eunice High School) was rewarded for her accomplishments in dressage on a national level, as well as her extensive scientific knowledge and ability shown at the Eskom Expo, the Eskom Science Fair, and an international science expo in Arizona, USA. Each of these winners received R5 000 from the Kovsie Alumni Trust.

Dr Pieter Rademan, Matriculant of the Year 2009, had this to say to the finalists — many of whom will start studying next year to become doctors: “I’m delighted to see that so many here are interested in medicine; there is a desperate need for more doctors and good doctors in the country.” Using an example from the Norsemen, he told the matriculants: “Despite being shipbuilders and seafarers, the Vikings would set fire to their ships when they reached their destination.” He said this ensured that they would be motivated to overcome difficulties before rebuilding their vessels to continue the voyage. He exhorted: “Burn your ships! Calm seas do not make for good sailors. Get out of your comfort zone and get comfortable with being uncomfortable.”

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.
