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.

She fought against illness, had to get the green light from medical personnel shortly before her main race, and was very nervous. However, on 5 June 2017, the blind athlete Louzanne Coetzee managed to improve the T11 5 000 m world record with more than 20 seconds.

The Kovsie star’s time of 18:14.27 at the ParAthletics Grand Prix in Nottwil, Switzerland, was approximately 23 seconds faster than her previous world record (18:37.23). In addition, Coetzee, who works at the Institute for Reconciliation and Social Justice at the University of the Free State, also improved the South African T11 800 m record to 2:30.18 on 2 June 2017, and her 4:59.54 on 3 June 2017 in the T11 1 500 m was almost another national record.

Carried by UFS and other support
“One could never be ungrateful when running close to your personal best,” Coetzee said. “Fortunately, with God’s blessing, the support of everybody at home, support from the university, as well as my mom and them, it really was a very blessed and successful event.”

According to her coach, Rufus Botha, Coetzee was not feeling well before the event and had to get medical clearance before the 5 000 m. He told her not to run too hard, even though their goal was 18:20. “She ran an incredible final 600 m, which brought the time down to 18:14,” he said. “It was amazing to watch.”

Botha’s knowledge valuable abroad
He enjoyed going overseas with Coetzee and her guide, Khothatso Mokone, for the first time. “His (Botha’s) experience, knowledge, support, and coaching was extremely valuable,” Coetzee said. “It will definitely help me in future: how to approach things, and everything he shared with us.”
