The Kovsies will face the Maties in the semi-finals of Varsity Netball in search of their fourth appearance in a final.
On Monday (30 September), the University of the Free State (UFS) netball team will have an ideal opportunity for revenge for what happened in this year’s Varsity Cup. In the semi-finals of the Varsity Cup back in April, the Shimla rugby team received a decent hiding from the Maties.

Now the UFS and Maties will face each other in another semi-final, this time in the netball version of the Varsity Cup, called Varsity Netball. The teams square off in the Callie Human Centre at 17:00.

Since losing to Tuks in the opening round, Kovsies have built up good momentum and confidence with six consecutive victories, including one over the Stellenbosch students on Monday (23 September). The score was 65-61.

The other wins were against UJ (69-35), TUT (64-20), NWU (59-55), Madibaz (70-41), and UWC (99-18), earning them the second spot on the log behind Tuks. The 99 goals against UWC were their best ever in the competition.The Free State women also won their encounter against Maties at this year’s USSA tournament by 38-31.

A victory would earn the team a shot at another Varsity Netball title. They have never lost a final, having appeared in three previous finals (2013, 2014, and 2018). Kovsies have won three of their previous five Varsity Netball semi-finals. They had met Maties only once before in a semi-final. This was last year in Bloemfontein when Kovsies prevailed by 56-45.
Khomotso Mamburu, goal defence of Maties, and Adéle Niemand, their assistant coach, both represented the Kovsies for many years.

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.
