Deputy Minister visit

“The work that the University of the Free State (UFS) is doing to ensure that students get the necessary support is quite impressive. The university is saving the academic year to save lives.” These were the words of the Deputy Minister of Higher Education, Science and Technology, Buti Manamela, during a visit to the university’s Bloemfontein Campus on 31 August 2020.

The visit was part of the Deputy Minister’s visit to higher education institutions in Bloemfontein to assess the academic state of readiness and to monitor the safety protocols for the phased re-opening of campuses during Level 2 of the national lockdown.

The delegation, which also consisted of representatives from Higher Health led by the Chief Executive Officer Dr Ramneek Ahluwalia, attended a briefing session in the Council Chambers before visiting various venues on campus. In his opening and welcoming remarks, Prof Prakash Naidoo, Vice-Rector: Operations, said that the safety, health, and well-being of staff and students remain the university’s priority. “Extensive planning has gone into making sure that the university complies with the national COVID-19 protocols and regulations and that our campuses are safe and ready for the return of students. Sufficient hygiene measures are in place, as well as adaptions to ensure physical distancing. The wearing of masks, physical distancing, and hand sanitising remain compulsory on all the campuses,” said Prof Naidoo.

“A Special Executive Group (SEG) was already established by the Rector and Vice-Chancellor, Prof Francis Petersen, at the beginning of March 2020. The SEG meets weekly to discuss and decide on the university’s response to COVID-19 as this pandemic develops over time. Consisting of eight task teams, the SEG is the decision-making entity that responds rapidly and in a coordinated manner to combat the threats to business continuity. One of the task teams is specifically looking at the wellness of our students and staff to make sure that this important aspect is taken care of,” said Prof Naidoo.

During a presentation of the university’s Multimodal Teaching and Learning Plan for the completion of the 2020 academic year, Prof Francois Strydom, Senior Director: Centre for Teaching and Learning, said that the university has an evidence-based approach towards remote multimodal teaching, learning, and assessment. “For instance, our vulnerable students were identified early in the lockdown, and 16 strategies were put in place to ensure that no student is left behind. 99,95% of our students were active on Blackboard. We are developing plans for the 0,05% of students who were not able to participate in learning, so that they can continue their learning journey with the UFS,” said Prof Strydom.

In his closing remarks, Deputy Minister Manamela commended the university management on the initiatives to save the academic year. He also indicated his appreciation for the informative session and encouraged the university to keep on motivating students and staff to be attentive to their behaviour and to remain careful about their health and well-being.

The programme was concluded with a visit to a number of venues on campus, including the examination venues, the Health and Wellness Clinic, the Pathogen Research Laboratory of the Division of Virology and a student housing unit.

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.
