Conduct research to advance sugarcane nutritional, agronomic and engineering technology.

Services

Provide services to support sugarcane farming best management practices.

Product Development

Transform research outputs into practical knowledge and technology products.

Technology Adoption

Facilitate the adoption of technology and best management practices that encourage responsible, sustainable and profitable land use.

Innovation

Generate new ideas to enlarge the scope of sugarcane agriculture and sustain the industry into the future.

Our History

In 1925, leaders of the SA sugar industry were prompted to established their own Experiment Station. The main reason for doing so was the need to introduce and select more productive and disease resistant varieties for the industry. At the time, the sugarcane disease, mosaic, posed a serious threat to the industry, as many promising varieties under test proved to be susceptible to the disease.

Dr WE Cross, Director of the Tucuman Research Station in Argentina, advised the SA industry not to rely on the inadequate number of government employed agricultural scientists working on several different crops, but to employ its own scientists in different disciplines to concentrate exclusively on sugarcane.
