With a new coach, new captain, and not having played a competitive match in more than a year, there will be many eyes on the Shimlas when they take to the field on 5 April.

The popular Varsity Cup is back, having been cut short by the COVID-19 pandemic in 2020.
The 2021 edition will be played in a secure bio-bubble at the University of Pretoria from 4 April to 24 May. The Shimlas will start with a clash against the University of the Western Cape. Matches will be played at the Tuks Stadium and Loftus Versfeld on Mondays, Thursdays, Sundays, and public holidays. 

There are high hopes after the return of Pote Human as head coach. He was previously in charge of the Shimlas from 2000 to 2004. Human knows what it takes to win the Varsity Cup, having done so with Tuks in 2017 before going on to coach the Bulls. 

Rewan Kruger, who is participating in his fourth campaign, will lead the team. 
The scrum half, who is studying BCom Accounting, said he felt humbled to lead the team.

“Hopefully I can lead in a way that takes this team forward. As a team, we strive to make a difference and the only way we can do that is if we play good rugby."
Kruger represented the Springbok U20 team at two Junior World Cups and captained the Free State U21 team in the past.

Human believes there is no shortage of talent in the squad. “I’m really excited to see what they can do. With most of the games being televised, they can make a name for themselves.”
“The guys have worked really hard during pre-season and are hungry to play rugby again. The set piece was a concern last year, but we have worked extremely hard on that.”

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.
