The Department of Business Management within the Faculty of Economic and Management Sciences is one of four successful recipients of the Nurturing Emerging Scholars Programme (NESP), which aims to recruit honours graduates who demonstrate academic ability and express an early interest in the possibility of an academic career. 

 “The NESP is a mechanism that addresses a potential shortcoming in the department in the medium to long term. Most of the academics in the department specialise either in entrepreneurship or marketing. As such, the availability of academics with interdisciplinary business knowledge who can teach and do research across the different sub-fields of business management is limited,” says Prof Brownhilder Neneh, Associate Professor in the Department of Business Management.

Once graduates enter the programme – as NESP master’s graduates they form part of a resource pool from which new academics can be recruited. 

Prof Neneh continues: “Considering the imminent retirement of academics in the department, the NESP provides an opportunity to recruit an academic who is able to work with experienced academics, gain experience, and ‘prepare’ the person to become an expert across the different fields in the department.”

“This programme would assist in succession planning within the department as well as training individuals within academia,” she says. 

According to Prof Neneh, access to this funding opportunity will further strengthen and expand the path that the department has embarked upon as far as striving for excellence in teaching, research, and community engagement is concerned, thereby contributing to address key societal challenges. “Appointing an NESP candidate would be an ideal opportunity to recruit an academic who will be able to work with the senior staff and gain experience and teaching/research competencies relevant to the 4IR, and ‘prepare’ the person to become the business management expert in the department,” she says.

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.
