Dr Faith Mkwananzi’s road from secondary school to university has been paved with challenges. After repeating her matric five times in Zimbabwe, she became an international university student in South Africa in 2006. Some years later, on 3 April 2019, the University of the Free State’s (UFS) Bloemfontein Campus witnessed the launch of her excellent book titled: Higher Education, Youth and Migration in Contexts of Disadvantages: Understanding Aspirations and Capabilities, which was informed by these and many circumstances.

Aspirations formation

The book speaks to her own life. “Born and raised in Zimbabwe in KwaBulawayo, I had my own aspirations. I knew I did not want be a nurse   my mother’s earnest interest and desire for me,” said Dr Mkwananzi as she related the fluid dreams her seven-year-old self had that culminated into aspirations to enter academia.

Aspirations enabled Dr Mkwananzi’s capabilities to pursue a PhD in Development Studies at UFS, and then write her book. “Higher education aspirations are worth pursuing,” said the current postdoctoral researcher at the university’s South African Research Chair Initiative (SARChI) in Higher Education and Human Development Research Programme, as she reflected on her academic journey.

Voices of marginalised migrants
 

Dr Mkwananzi has focused her book on the lives, experiences and the formation of higher education aspirations among marginalised migrant youth in Johannesburg. She gives these young people a voice to narrate their own story, making this research an essential work for understanding the conditions necessary for youth to live valuable lives in both local and international contexts.

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.
