The month of October 2020 marked the first anniversary of the Qwaqwa Campus online student radio, Q-Lit. “It has been a rocky road of sleepless nights, tears, and a lot of challenges. However, we have grown from strength to strength. We have made dreams of ordinary students possible. We have influenced change and inspired students to tap into their talents and potential,” said an elated station manager, Mbuyiselwa Moloi.
The station came in handy during the worst lockdown period of the COVID-19 pandemic when it bridged the communication gap between students and the university to integrate teaching and learning into the programming to ensure that no student was left behind. “With all of the regulations and online learning, Q-Lit had to be reinvented. While it was not an easy journey, we have grown more than ever before. Our August 2020 report shows that we have pulled in more than 1 600 listeners, even amid the learning, unlearning, and relearning processes. It was during this month that we also ran a series highlighting strategic offices led by women on campus as part of our Women’s Month celebration,” Mbuyiselwa revealed.
Looking to the future, the station hopes to obtain a full broadcasting licence from the regulatory body, the Independent Communication Authority of South Africa (ICASA), soon.
Plant eco-physiologist finds effective solutions for crop optimisation
2016-07-24
The bio-stimulant was tested on
this citrus. This is the first time
that the product has been tested
on a crop.
In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.
Role of photosynthesis and plant sap data
By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.
Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.
Agricultural and mining sectors benefit from research
The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.
The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).
Soil rehabilitation key aspect in research projects
“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.
Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
