Takudzwa Nyamunda.
Takudzwa Nyamunda is the proud new representative of the University of the Free State (UFS) for the 2020 Commonwealth Future Student Leadership programme. Nominated at a recent workshop themed ‘Reimagining Peace’, organised by the Association of Commonwealth Universities in collaboration with the British Council and the Durban University of Technology, Takudzwa demonstrated exceptional leadership, coupled with his experience of issues related to the UFS student committee, which provided the perfect foundation for his selection. 

“From a personal point of view, this was one of the most enriching experiences I have ever had, both in terms of the relationships established and the world knowledge gained. I am personally grateful for the opportunity to attend and would support any further initiative of this nature. I think the essence of this workshop was to encourage the young leaders present – all of whom were active citizens in their communities in one way or another – to continue fighting the good fight. The core message from the panellists was that it is all worth it in the end, and that even in the face of adversity and discouragement, we should keep fighting for the work we believe in,” says Takudzwa. 

Participants from 13 nations, including activists and thought leaders on non-violence affiliated with the International Centre of Nonviolence, the Gandhi Development Trust, and the Commonwealth Countering Violent Extremism Unit, contributed to the workshop. Over the course of three days, participants were divided into five groups and worked together on projects linked to three main themes – gender-based violence, global warming, and inequality.

The selection committee was convened by the Vice-Rector: Research and Internationalisation, Prof Corli Witthuhn, and facilitated by the Office for International Affairs. Currently in the final year of his Master of Industrial Psychology degree, Takudzwa’s wealth or experience includes being the founder and first president of the International Students Association (2016), and holder of the International Student portfolio as Student Representative Council (SRC) member (2017), coupled with being co-founder and first vice-chairperson of the South African Board for People Practices (SABPP): UFS Chapter and Vice-president of the SABPP National Youth Council (2019).

“I will continue to do what I have been doing for the past five years at the UFS, which is to make a difference in my sphere of influence”, says Takudzwa.

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.
