Prof Pearl Sithole acknowledged the role played by the Afromontane Research Unit in securing mountain-to-mountain research funding from the US Embassy and Consulates in SA.

“This launch is an opportunity to reflect on the strategic significance of the partnership between our two universities and the long-standing relationship that academics at the two institutions have enjoyed.” 

These were the words of appreciation from the University of the Free State Vice-Rector: Research, Innovation and Internationalisation, Prof Corli Witthuhn, during the virtual launch of the Mountain-to-Mountain collaboration project between the University of the Free State and the Appalachian State University in the United States held on 10 November 2020. The R8 million project is funded by the US Embassy and Consulates in South Africa and will run over two academic years.

Prof Witthuhn also stated that the project would further strengthen the UFS strategy for internationalisation. “This collaboration has grown organically in the last decade to become one of the UFS flagships in international collaborations. With the support of this grant from the US Embassy and Consulates in South Africa, this long-standing and sustainable collaboration will be further strengthened,” she added.

New master’s programmes

In providing context to the Qwaqwa Campus’ research footprint, Campus Vice-Principal: Academic and Research, Prof Pearl Sithole, acknowledged the role played by the Afromontane Research Unit (ARU) under the leadership of its Director, Dr Ralph Clark, as well as all the faculties.

“In the Humanities, a lot is coming regarding the socio-ecosystems of the mountains. And in Education and Economic and Management Sciences, the scholarship of teaching and learning is promoted through blended skills, especially during this time of the pandemic. In the Natural and Agricultural Sciences, climate monitoring is one of the projects that has brought vibrancy to our campus,” she said.

Appalachian State University’s Associate Vice-Chancellor for International Education and Development, Prof Jesse Lutabingwa, mentioned that the collaboration would, among others, develop and offer a multi-disciplinary master’s degree in Mountain Studies on the Qwaqwa Campus, which will initially enrol seven to ten students. “In the subsequent years, we plan to increase this number to 15-20 students. We will also develop and offer a Community Development master’s degree with 10-12 students and up to 25 in subsequent years.”

Black women academics

Prof Lutabingwa, who is also the Project Director, revealed that doctoral students who are currently part of the University Staff Doctoral Project (USDP), will conduct at least three research projects focusing on social entrepreneurship, substance abuse, and rural transport monitoring in the Maloti-Drakensberg Mountains. “Also key to this collaboration is the leadership mentorship programme for black women academics who will at the end of the project produce three to five research papers,” Prof Lutabingwa added.

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.
