Lefébre Rademan
Lefébre Rademan, new captain of the Free State Crinums netball team, could be one of the star players in the Premier League. She is a fifth-year Education student.
The Free State Crinums netball team, a de facto Kovsie team with all 15 squad members enrolled for courses at the University of the Free State (UFS), will draw inspiration from their success in last year’s Varsity netball tournament. The Kovsies won the student competition for a record third time. 

During the weekend of 10 May 2019, the Crinums will play their first match in the 2019 Premier League. They lost a couple of key players in captain Alicia Puren, Protea Khanyisa Chawane, (both playing for the national invitational team in the league), Khomotso Mamburu (moved to Cape Town), and Meagan Roux (injured). They do, however, still have the services of players such as Tanya von Berg (playing in her sixth Premier League, one of only a handful of players to do so), Lefébre Rademan, Sikholiwe Mdletshe, Ané Retief, Gertriana Retief, and Rieze Straeuli. Rademan is the new captain and was one of the standout players in last year’s Varsity netball, earning three Player of the Match awards, including the Player of the Final. 

The team will again be coached by Burta de Kock, who is also the head coach of the Kovsies. Under her leadership, the Crinums won the Premier League for the first three years (2014 to 2016). Last year, the Crinums ended fourth. De Kock will be assisted by Martha Mosoahle-Samm. She is a former Protea assistant coach who also captained South Africa and played for the UFS between 1997 and 1999.

There are four first-year students in the squad of 15 players: Oageng Khasake (wing attack), Ancia Pienaar (goalkeeper), Rolene Streutker (goal shooter), Boitumelo Mahloko (goal defence). Pienaar and Mahloko both represented South Africa at junior level in 2018.

■ Crinums squad: Ané Retief, Gertriana Retief, Jana Scholtz, Lefébre Rademan, Sikholiwe Mdletshe, Tanya von Berg, Rieze Straeuli, Claudia van den Berg, Zandré Smit, Oageng Khasake, Bianca de Wee, Ancia Pienaar, Rolene Streutker, Chanel Vrey, Boitumelo Mahloko.

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.
