University leaders from Africa and beyond will take part in a Regional Universities Forum for Capacity Building in Agriculture (RUFORUM) webinar on Wednesday, 10 June, to look at universities’ responses to the COVID-19 pandemic. Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State, will be one of four panellists who will be the main speakers of the day. He is the only panellist from South Africa. 

Prof Petersen will participate alongside university leaders such as Prof Arthur Mol, Rector Magnificus of Wageningen University and Research in the Netherlands, Mr Hicham el Habti, Secretary General at the Mohammed VI Polytechnique University (UM6P) in Morocco, as well as Prof Barnabas Nawangwe, Vice-Chancellor of the Makerere University in Uganda. 

Getting together with other university leaders from the continent and abroad, speakers will share insights from their respective countries in dealing with the pandemic. The webinar takes place on 10 June 2020 at 13:00 South African time (14:00 East African Standard Time)

RUFORUM is a consortium of 46 universities in Eastern, Central, Western, and Southern Africa mandated to oversee graduate training and networks of specialisation in the countries and universities where it works. 

What is the webinar about?
The RUFORUM webinar titled ‘Learning from a crisis: University leaders’ response to the COVID-19 Pandemic', aims to tackle issues such as the immediate needs of universities, including staff realignment, dealing with the digital divide in the student community, institutional finance for operations and innovations in a changing landscape, and international students in a crisis moment. 

This webinar provides a great opportunity to galvanise collective responses from university leaders on this pandemic. It brings together universities from within and outside Africa on lessons learnt in confronting the immediate challenges and how they are resetting for a long-term perspective in the ‘new normal’. Interactions during this webinar will hopefully lead to a consensus on strengthening collective response and how universities can leverage one another in terms of the best practices and resources.  

The impact of the Coronavirus on higher learning institutions 
Given the devastation caused by COVID-19 across the world since its outbreak in China in December 2019, the impact has been felt in all spheres of the economy and global operations. Universities have also seen significant interruptions, including the UFS. Recently, RUFORUM conducted a study on the readiness of African universities to respond to COVID-19 and other natural disasters. This was meant to determine the level of preparedness of our institutions in facing this global pandemic and how to move forward as a continent while preserving the quality of the higher education that we deliver.  

The webinar will build on those findings and project a way forward in this unchartered territory of diminished financial resources, personal and academic challenges for staff, students, and institutional systems, the urgent need for improved infrastructure to respond to the demand for blended learning as well as remote learning approaches, and the limited mobility of students, academic and other staff, among others. Addressing these issues resulted in collaborations such as those initiated by RUFORUM.

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.
