Mental health awareness
The UFS joined the global community in commemorating World Mental Health Day.

“This is not a conversation that should wait until people have taken their own lives or have been diagnosed,” said Tshepang Mahlatsi, Founder of Next Chapter, a student organisation that advocates for mental health. In commemoration of World Mental Health Day, the organisation hosted a dialogue around this year’s theme of Mental Health Promotion and Suicide Prevention on 10 October 2019.

Mahlatsi further said: “The conversation around mental health is not one that should be reserved for September or October when we commemorate suicide prevention and World Mental Health Day. We should build a culture and tradition of having and normalising these conversations. This notion becomes highly relevant at institutions of higher learning where most students are affected by various factors, such as finances and academic anxiety.”

Dealing with the dilemma

This open discussion took place on the Bloemfontein Campus between students and a panel comprising Dr Ntswaki Setlaba and Dr Melissa Barnaschone.

Dr Setlaba, a consultant psychiatrist at Pelonomi Tertiary Hospital, said one of the symptoms of major depressive disorder is suicide. She highly recommends that early detection of depression is essential in order to prevent it escalating to a loss of more lives.

Director of the Office for Student Counselling and Development, Dr Barnaschone, supported the concept of early detection, citing that there are plans put in place to support students, such as workshops and the Student Mental Health Toolkit.

Medicine of the mind

Dr Fanie Meyer, a private psychiatrist based in Bloemfontein, described to staff members the effects of depression and anxiety on the brain. He presented a talk titled: Pain vs Depression: ‘The chicken or the egg?’ which was hosted by the Organisational Development and Employee Wellness division in collaboration with the Faculty of Health Sciences.

He also stressed the importance of early detection. “If you leave your pain running for 10 years, it will get worse. The same goes for anxiety,” said Dr Meyer. 

According to Burneline Kaars, Head of the Division, they are committed to changing attitudes about mental health and reducing the stigma experienced by those who live with it. “The focus is on educating staff about mental illness and empowering them to take action and promote mental wellbeing while it is still early.”  

Recognising the early symptoms of a mental disorder is an essential part of tackling the pandemic. Having the mental health conversation throughout the year instead of in September and October ought to further this agenda.

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.
