Lupin phenology and yield responses to environment and management practices – Wagga Wagga and Rankins Springs 2023

Abstract

Key findings • Below average rainfall, frequent frosts, and high temperatures during the grain filling phase significantly reduced grain yield potential at both experiment locations. • Early sowing at Wagga Wagga increased biomass and grain yield without affecting seed weight. At Rankins Springs, early sowing increased biomass but did not affect yield or seed weight. The average grain yield was 2.5 t/ha at Wagga Wagga compared with 0.8 t/ha at Rankins Springs, a 68% reduction due to more adverse spring conditions. • Higher-yielding conditions (Wagga Wagga): PBA Jurien[PBR], PBA Bateman[PBR], and Mandelup[PBR] had the highest yields. Constrained conditions (Rankins Springs): Jindalee had the highest yield, especially with early sowing.
