The University of the Free State (UFS) has joined The Conversation Africa (TCA) as a funding partner.  TCA, a not-for-profit media initiative, is part of a global platform that publishes articles written by academics and researchers.  The platform’s objective is to make the knowledge produced in the academy accessible, easy to understand, and freely available to the general public. Articles are published daily on the TC-Africa website - https://theconversation.com/africa. 

The platform uses a Creative Commons republishing model. This means articles can be republished by other media on the continent and internationally, ensuring even greater reach to audiences including academics, policy makers, funders, and the general public. 

To date, more than 55 UFS researchers and academics have published with TCA, and their articles have garnered more than 1,3 million readers globally. UFS researchers and academics are encouraged to publish with The Conversation. 

As part of the partnership, TCA will run writing workshops for UFS academics and researchers who want to enhance their writing and science communication skills. Dates for these will be announced soon.

How you can publish with The Conversation Africa

• Engage with The Conversation Africa editors when they contact you directly to write about your research area and expertise. The articles are short, ± 800 to 1 000 words.

• Pitch your idea for an article directly to The Conversation Africa here   

• Register as an author, and set up a profile

• Engage with the Communication and Research offices. Every week, The Conversation Africa sends an expert request for expert authors on topical issues to the Communication and Research offices, which can identify researchers. 
- Interested researchers are put into contact with the relevant editor at The Conversation to discuss the potential article

Why should you get published on The Conversation Africa?

Benefits for researchers and academics:

• Articles on the platform help to raise the profile of academics, often leading to policy engagement with governments, businesses, industry or professional bodies, conference invitations, academic collaborations, and further media exposure. 
• In the course of writing, academics get bespoke editorial assistance from the team working in consultation with them. 
• The opportunity to take part in a hands-on science communication writing workshop.
• Readership and republication metrics for each published article.
• A global readership with up to 1,2 million readers monthly.

Benefits for Communication and Marketing and the Research office:

• Provides well-curated, ready-to-use communication material for websites and social media. 
• Helps to profile the work of the university for marketing, communication, and awareness.
• Provides media exposure to the talent pool of UFS academics and researchers. 

Benefits for and across the university:

• Shines a spotlight on the excellent research and innovation at the UFS.
• Demonstrates the UFS’ commitment to facilitating greater engagement with society and promoting interdisciplinary communications.
• Visibility for the institution and researchers nationally and globally.
• Access to institutional analytics, including detailed data on the content published by UFS researchers.

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.
