FAST FACTS
- Cultivar choice is an important production decision and can contribute to reducing risk and optimising yield.
- A producer should use good-quality seed and maintain appropriate seeding densities, as the plant population may significantly affect competition among plants as well as weeds.
- Seeding densities for wheat may vary from 15kg/ ha to 35kg/ha under dryland conditions, and 65kg/ha to 200kg/ha under irrigation.
Knowledge is crucial to success in crop production, and seldom more so than for wheat in South Africa, where growing conditions vary and much of the country’s supply is imported. Producers need to base short- and long-term planning on the latest market and industry information so they can adapt when required to increase profit per hectare.
To succeed, a farmer has to understand his or her specific production area, take note of long-term climate conditions, and keep up with the latest cultivars.
CHOOSING CULTIVARS
Cultivar choice is a key production decision and can contribute to reducing risk and optimising yield. The selection of a cultivar is principally an economic decision, where the producer must find a balance between risk and yield potential. The yield potential of the wheat, in combination with the production area, climate and soil type, is as important as the management of input and production costs.
Cultivars differ in characteristics such as area adaptability, yield potential and stability, agronomic characteristics, as well as tolerance of diseases, pests and aluminium toxicity. New varieties are released frequently, and it is important to understand their characteristics and how they fit into the farm’s cropping system.
