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.

Chakalaka can have side effects for these patients
2010-06-24

Chakalaka is a sauce many South Africans cannot imagine a meal without, but research at the Faculty of Health Sciences at the University of the Free State (UFS) has shown that it can have serious side effects and even compromise the treatment of leukaemia patients.

Prof. Vernon Louw from the Department of Internal Medicine at the Faculty says that tyrosine kinase inhibitors (TKIs) are a new group of drugs providing targeted therapy for chronic myeloid leukaemia (CML). It vastly contributes to the survival of patients, but it has side effects like vasodilatation. Research has shown that spices like chakalaka may aggravate vasodilatation (widening of veins) with patients on these drugs.

“These spices produce serious oedema (water retention) and headaches. We have found that discontinuing the intake of spices allows some patients to maintain therapeutic doses of TKIs.” Chakalaka contains mainly garlic and chilli.

CML represents up to 20% of all leukaemia patients in South Africa and up to 450 new cases are reported every year.

In the study symptoms of severe headache and oedema disappeared within days of discontinuing the use of chakalaka.

Prof. Louw says it is important for oncologists to ask their patients about their intake of spices and garlic when they are on TKIs. It is also advisable to enquire about the use of complementary alternative medicine as the interaction of these medicines in cancer treatment is not known.
