The UFS netball team celebrating their victory in last year’s Varsity Netball competition. They are the most successful team in the tournament’s history, with three titles (2013, 2014, and 2018).
Kovsies can lift the Varsity Netball trophy again if they repeat last year’s recipe of playing for each other, motivating one another, and giving their all in each game. This is what the captain, Lefébre Rademan, believes. 

The competition started yesterday, Monday 26 August 2019 with a repeat of last year’s final. The UFS women played Tuks in the Callie Human Centre at 19:00. The final score was Kovsies 42 - 63 Tuks.

“I believe we can retain the trophy if all the players’ heads and hearts are in the right place. We must play for each other and for the UFS. I don’t think we have a point to prove after what happened at the USSA, although we would like to set the record straight,” Rademan said.

The UFS netball team went unbeaten through the group stage of the USSA champs in July, but they lost their final two encounters to finish fourth.

The Kovsies received the best possible draw. Five of their seven matches are at home, three of them against traditional powerhouses Tuks, North-West University, and Maties. They only have to travel once (to Pretoria), where they will play matches on consecutive days.

“It is certainly a great advantage to have so many matches in front of your home support and only playing away twice (against the Madibaz and the University of the Western Cape).”

Rademan took over the captaincy from Alicia Puren, who finished her studies at the end of 2018.

The team also lost the services of Maryke Coetzee, Khomotso Mamburu, and Tanya von Berg, who were all extremely experienced.

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.
