Volunteer students participating in a two-day training by KovsieACT to learn fundamental principles of gardening, including soil preparation, planting, watering, fertilising, and pest management.
To ensure food security for students, KovsieACT – in collaboration with the Department of Sustainable Agriculture and Food Systems – held training sessions for approximately 150 student volunteers at the University of the Free State (UFS) community gardens on the Bloemfontein Campus. 

The UFS project consists of two large food tunnels, which provide an educational intervention that addresses food insecurity on campus, and by extension, food insecurity challenges students experience in their hometowns, at home, and in their villages.

Karen Scheepers, Assistant Director: Student Life, said: “The purpose of this training is to equip students with the necessary skills to identify or recognise the need for and importance of planting and taking care of vegetables. Participating students also learned the fundamental principles of gardening, including soil preparation, planting, watering, fertilising, and pest management.”

During the training held on 8 and 9 March 2023, students were also trained to choose the right seeds and to start their own seed germination project. “The aim is to provide students with the knowledge and skills they need to grow and maintain a thriving vegetable garden,” added Scheepers.

The training was conducted by experienced professionals from the department, with students also getting an opportunity to ask questions and interact with fellow students who share their passion for gardening.

Scheepers said: “This training is a great opportunity for students to learn new skills, make new friends, and connect with the community. It will also help them to lead a healthier and more sustainable lifestyle.

The training is an extension of the institution’s No Student Hungry Programme (NSH), which continues to ensure that hundreds of students are supported with food parcels, including vegetables and non-perishable items. The NSH programme provides food to insecure students through modest food allowances and daily access to one balanced meal.

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.
