Muthianzhele Ravuluma receives an award from Prof Sebastian Leuzinger from the Auckland University of Technology in New Zealand.

A PhD student from the University of the Free State (UFS) has won the International Society for Horticultural Science (ISHS) Young Minds award for the Best Paper and Best Poster Presentation during the 12th International Workshop on Sap Flow, which was held in Rotorua, New Zealand.

Muthianzhele Ravuluma from the Department of Soil, Crop, and Climate Science who is working on his PhD in Agrometeorology, presented a paper on “Sapflow Dynamics of Young and Mature Pomegranate Trees Under Irrigation” during the four-day symposium that took place between 30 October and 3 November 2023. Agrometeorology is the study of the soil, plant and atmosphere continuum. In simple terms, it is called agricultural meteorology, which is the study of the influence of weather and climate on agriculture.

Encourage do and learn more 

“I feel thankful to being given an opportunity like this, and winning the award was a surprise. Still, I am happy and grateful for the support from my promoters and the Pomegranate Water Use Project members. This encourages me to do more and to learn more about new technologies in the field of agriculture,” he says. 

Ravuluma travelled to New Zealand with his promotor Dr Phumudzo Tharaga to present his research and to learn from other researchers is the field. His research looks at the water use of pomegranate trees under irrigation in a Mediterranean climate. 

A proud Dr Tharaga says he is happy to know that the guidance he has been giving to Ravuluma is fruitful and improving his academic and research capabilities. “I feel proud as a supervisor, which makes my dream come true of ensuring that all postgraduate students can showcase their work on international stages,” says Dr Tharaga. 

Hosting next symposium 

Together with Prof Rob Skelton from Wits University, they also successfully bid to host in the 13th International Sap Flow Workshop in South Africa – beating China and the US in the process. All three colleagues will collaborate as conveners of the workshop in South Africa during October/November 2026. 

“It is an honour to be recognised and entrusted by the international community of scientists who would like to showcase their work in South Africa. As the convener of the conference, I am happy that it will be hosted in our country for the first time since the inception of the Sap Flow Working Group. Scientists and researchers in South Africa will be able to interact with their peers from different parts of the world,” concludes Dr Tharaga.

Dr Phumudzo Tharaga congratulates Muthianzhele Ravuluma on winning the  prestigious award.

Whether it’s the 5 000 m or the 1 500 m, Louzanne Coetzee is breaking records in all her races. Fans of the University of the Free State (UFS) student were elated at her triumph with the 5 000 m T11 world record at the Nedbank National Championships for the Physically Disabled on Wednesday 23 March 2016.

The record, which has stood for 16 years, was shattered by Coetzee’s stellar 19:17.06 performance. Sigita Markeviciene’s long-standing mark of 20:05.81, set at the 2000 Paralympics in Sydney, was bettered by 48.75 seconds when Coetzee and her guide, Khotatso Mokone, sprinted hand in hand past the finish line. 

Coetzee’s coach is as elated as the world-class athlete’s fans over her officially becoming the first totally blind female to clock sub-20 minute in the 5 000 m. "I am proud and grateful. She earned it through and through. She worked hard for this,” said Rufus Botha.

The experience was a surreal one for Coetzee. “It was unreal but it is exciting to be the fastest in Africa and the world. I could not have done it without the support system that I have,” she said.

"I have seldom met a student with the character and humanity of Louzanne Coetzee; she represents the best of campus and country, and is a stunning example of what we canal  achieve despite the great challenges of the present," said Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

New African record holder

Two days before breaking the 5 000 m world record, Coetzee set a new African record in the 1 500 m. She lowered the mark from 5:27:21 to 5:18:44, which placed her at the number nine spot in the world.

On Friday 18 March 2016 Coetzee had broken her own South African record when she ran 5 000 m in less than 20 minutes at the Free State Championships. However, the race is not an official (International Paralympic Committee) meeting, and hence remains unofficial.

What’s next?


The gold medallist is currently preparing for the Athletics Grand Prix to be held in Switzerland in May for which she is raising funds. If she is selected by SASCOC (South African Sports Confederation and Olympic Committee), her next stop is the Paralympic Games in Rio de Janeiro, which is just six months away.
