Safflower agronomy research in NSW

Abstract

Key findings •In the 2021/22 growing season, the performance of super high oleic safflower (SHOS) crops in NSW was mixed. Benchmarking highlighted varying agronomic practices. Crop establishment, in-crop management practices and crop yields were inconsistent. •Overall confidence of growers and agronomists in their agronomic knowledge of safflower is low. •There is an incomplete understanding of safflower’s role in different farming systems. Robust information surrounding safflower’s legacy effects on pathogens, weed species dynamics, soil nutrient use, soil water and soil structural changes is required. The reasons for the responses in subsequent crops are often simplistic and frequently rely on anecdotal evidence. •Safflower has the capacity for growth compensation to adjust to variable growing conditions. Better knowledge of safflower physiology and adapting crop management practices to suit regional environments will maximise water use efficiency (WUE) and yield potential. •Care is required to ensure crop performance expectations of this new industry are realistic with current crop genetics. •Ongoing research, development and extension will be crucial to ensure SHOS achieves its potential and becomes a reliable and profitable component of farming systems.
