Virtual Exhibition Is Now Closed

 

Art in itself is a journey of self-exploration; with a global pandemic raging, art lovers can now explore this journey virtually. The Johannes Stegmann Gallery at the University of the Free State (UFS) is happy to announce the (second) virtual exhibition of Leeto: a Sam Nhlengethwa Print Retrospective until 4 September 2020.

The exhibition features a collection of Sam Nhlengethwa’s print work to be interrogated, his artistic evolution to be mapped out, and his personal aesthetics to be interpreted, while surveying this renowned artist’s print work from 1978 to 2018.  The underlying theme of the exhibition is jazz, an early influence in Nhlengethwa’s works from the underground jazz community of the townships. His brother was a jazz musician and he started collecting jazz records from the early age of 17.

Leeto is a Setswana/Sesotho word for ‘journey’ and, as the word suggests, the exhibition explores the ongoing artistic footsteps of the artist. The collection was curated by Boitumelo Tlhoaele, a doctoral fellow in the Africa Open Institute for Music, Research, and Innovation at Stellenbosch University.

About the artist: 

Nhlengethwa began his career in 1976 during one of South Africa’s most tumultuous socio-political eras. In 1978, he completed a two-year diploma at the Evangelical Lutheran Church Art and Craft Centre, Rorke’s Drift, KwaZulu-Natal, where printmaking was a prominent feature of the centre’s activities. Nhlengethwa’s work spans a variety of mediums, from painting, drawing to collage, and some of his works have been translated into tapestries. One of his big cityscape works was translated into a mosaic. In addition to all the afore-mentioned mediums, Nhlengethwa also produced an impressive and sizeable body of printmaking works. 

He has collaborated with several South African printmaking studios, such as The Artists’ Press, Artist Proof Studio, David Krut Print Workshop, LL Editions Fine Art Lithography Studio, MK and Artist Print Workshop, Mo Editions Printmaking Studio, and Sguzu Printmaker’s Workshop. Since 1994, he has produced 163 prints in collaboration with The Artists’ Press, making it his longest and most productive affiliation.

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.
