Prof LenkaBula promotes partnership with German University

The University of the Free State (UFS) Vice-Rector: Institutional Change, Student Affairs, and Community Engagement, Prof Puleng LenkaBula, recently visited the Fulda University of Applied Sciences in Germany to discuss a possible future collaboration between the two institutions.

This was inspired by their multidisciplinary approach to higher-education courses, which she aims to facilitate at the UFS in order to pioneer critical thinking among students to ultimately bring about effective and innovative societal problem-solving in South Africa.

Fulda University is an exceptional higher-education institution with the ability to develop and transform itself to purposefully improve its infrastructure, the quality of students, and studies offered by the university. Their different degrees are structured to intersect with the requirements of the progressive European economic environment.

According to Prof LenkaBula, Fulda University is an outstanding institution specialising in applied sciences and theoretical studies, which set them apart from other universities in the advanced European higher-education system.

Prof LenkaBula believes that the prospect of developing joint master’s and/or doctoral degrees between the UFS and Fulda University would expose UFS students to high-quality international higher-education systems. This will ensure that our students are provided with essential skills to become globally competitive and relevant in their designated career fields, and to become strong contenders in an environment characterised by globalisation and the 4th Industrial Revolution (4IR).
She referred to the global exchange of knowledge systems between the UFS and Fulda University as an opportunity for the UFS to improve the university’s global rankings through learning and participating in international collaborative approaches in higher education.

“In order for our university to cease being seen as an ivory tower, it must be involved in producing knowledge that is beneficial to socio-economic and political development – not only for South Africa, but also for the rest of the world,” said Prof LenkaBula.

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.
