Projections indicate that by 2020 about 80% of all jobs will require some level of competency in Science, Technology, Engineering and Mathematics (STEM). Also, given the rising unemployment rate and the subsequent demand for entrepreneurial skills in the past few years, STEM education has become a priority for South Africa.

A step in the right direction

Equipping young people to be efficient in the world of work and business is a major driver behind the country’s education system. The MEC for Education in the Free State reiterated the importance of STEM subjects. Dr Tate Makgoe addressed about 200 top-performing Grade 12 learners from quintile 1-3 schools in the province who were attending the South African Institute for Chartered Accountants (SAICA) maths camp.

Making mathematics fashionable

The week-long camp recently closed with an awards ceremony which was held on the Bloemfontein Campus of the University of the Free State (UFS). Nine of the creams of the crop of matric learners were honoured for their achievements in mathematics, physical science, and accounting.

Zinhle Gumbi, from Morena Mokopela Secondary School, one of the three Mathematics Top Achiever award recipients has become more determined to choose a maths-related profession. “I have told myself that any career I follow must include maths. Dr Tate Makgoe said we must prove to people that the black child can do it.”

Emerging as one of the Accounting Top Achievers was Albert Ramatsekane from Tsoseletso Secondary School who intends to pursue a Chartered Accountant (CA) qualification. “The camp has boosted my confidence. Now I can choose the CA stream without thinking twice.” 

Sowing the seed and reaping the fruits

Accounting lecturer Mojalefa Mosala was satisfied with the results of the camp. “I am happy to see many familiar faces in my classes who have attended previous camps. It means we’re doing something right.”

Mosala, a former assistant camp organiser, has confidence in the project as it “affords a rare opportunity to learners who have not been exposed to information, the higher learning environment, study skills and motivational figures to experience all of these”. 
Kovsies prides itself in partnering with industry stakeholders to build the future of the country, one maths camp at a time.

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.
