Siphilangenkosi Dlamini – selected by Inside Education and the NYDA as one of South Africa’s 100 Shining Stars for 2022.

Siphilangenkosi Dlamini, a fourth-year Governance and Political Transformation student at the University of the Free State (UFS), has been selected as one of South Africa’s 100 Shining Stars for 2022 by Inside Education, in partnership with the National Youth Development Agency (NYDA). 

“I was more surprised than anything, but also very honoured,” he said. Dlamini, who made it into the Civil Society and Youth category, was chosen from a pool of 800 applicants for his remarkable work with the Help a Student initiative, and his services as the former secretary of the Southern Africa Scout Youth Forum. Although he could not attend the award ceremony held in Johannesburg on 20 October 2022 in person, Dlamini did receive a certificate. “What we do a lot of the time isn’t for recognition and it’s not necessarily for awards; but getting recognised motivates and assures me that the work we are doing has an impact,” he expressed.

The Help a Student Initiative

In the early stages of the COVID-19 pandemic, Dlamini recognised a rise in food insecurity among his fellow students. This set him on a path to source funding for the establishment of the project. 

The Help a Student initiative aimed to curb food insecurity through the provision of food parcels to UFS students who were in need. The project, which ran from 2020 until early 2021, managed to distribute food parcels to nearly 250 students per month. The initiative did not only assist students who were on campus. The selected applicants who were at home or off campus also received digital food vouchers, which allowed for the purchasing of food items at Pick n Pay and/or Shoprite.

“Food security is something that I am passionate about. I grew up in a community where it was a massive issue.

However, in the past I was not empowered enough to know how to solve it. Therefore, when the opportunity presented itself to do something about it, I took it with both hands,” Dlamini expressed.

Although the recognition was not expected, Dlamini maintains that such platforms are imperative, as “they demonstrate that young people are doing something to improve the country in the different capacities they are in”.

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.
