From an early age, many have been taught that strangers are not only a danger to the individual, but to the communities too.

A StrangerKind (ASK), an organisation hosting unconventional conversations in communities on topics and responding to questions that many may not have the opportunity to ask, has partnered with the University of the Free State to host the talks that aims to promote curiosity, diversity, and social cohesion.

As part of the ASKcampus – a first to be hosted at any university in the country – participants will have an opportunity to talk to a stranger in a safe setting and ask any question that comes to mind, without any judgement.

Michelle Nöthling, Assistant Researcher in Kovsie Support Services, said: “The ASK event is an opportunity for participants to pick a topic from a list that sparks curiosity and book an available 45-minute time slot. During your session, you sit down to a one-on-one conversation with a stranger who will briefly introduce themselves and their topic. They will then share their personal life experience on that topic with you.”

The event, which will be launched at the Thakaneng Bridge, Bloemfontein Campus, on 28 July 2022, is open to both UFS staff and students.

“During the individual sessions, participants may ask the strangers anything about the chosen topic. We even encourage you to ask those questions that you might otherwise have been too shy, or felt were too ignorant, to ask. What is more, is that the strangers you will meet will be fellow UFS staff and students. But you will not know who your stranger is until you sit down with them,” said Michelle.

Individuals who want to know more about becoming a UFS stranger are encouraged to visit the organisation’s YouTube channel or register to attend training and become a ‘stranger’.

Be curious. Be brave. Talk to strangers.

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.
