Potato Nutrition

  • To do research in controlled environments to determine the effect of soil temperature on Ca uptake and internal quality characteristics.
  • To evaluate the value of a unique system to do research on the effect of soil temperature on the root environment.


  • A rapid method to determine the culinary characteristics of a specific batch of potatoes.
  • Knowledge of how our climate affects the culinary qualities of locally produced potatoes.
  • Information on safe and effective postharvest sanitisers.
  • Identify where weight loss occurred most in the process of harvesting to market.

Nematode management

  • To evaluate the relative tolerance of cultivars to root-knot nematodes.
  • To evaluate the effectiveness of “softer” nematicides, rotation programmes, cover crops, etc. to manage nematodes.
  • To determine how different crops used in rotation programmes in the Eastern Free State affect the nematode population.

  • To observe effects such as tillage, cover crops, rotation crops etc. on soil microbes, soil physical and chemical properties, yield and quality.

Virus and aphid management

  • To maintain a long term database to determine changes in aphid flight and abundance as affected by climate, alternative host plants, etc.
  • To monitor seasonable aphid flights.
  • To determine how climate and climate change may change the flight pattern, species composition and abundance by using long term data.
