Optimising sunflower performance relies on being able to match a hybrid with the growing environment and ensuring that the most suitable agronomic management is provided. Suitable crop agronomy involves using the most appropriate row configuration and plant population as well as ensuring adequate nutrition, disease and insect management. This experiment and others conducted in this series were designed to provide recommendations for growers and advisors to support decisions on optimal row configuration, plant population and hybrids for sunflower production in the north-western and Liverpool Plains regions of NSW. These two environments are the primary sunflower growing regions in northern NSW.
