Plant nutrition

Department of Primary Industries and Regional Development conducts and supports research into the agronomic requirements of a range of crops to provide information on crop nutrition to ensure optimum yields and quality. Plants require a number of nutrients to successfully grow and produce a crop. Western Australia's weather conditions can result in poor soil fertility and limited water supply which restrict a plants ability to uptake and use nutrients.


  • Cauliflower and broccoli crops generally require multiple harvests to remove all marketable curds or heads. By improving the uniformity of plant maturation, crops can be harvested in a single pass.
