Lupin phenology and yield responses to sowing date and water treatment – Wagga Wagga and Rankins Springs 2021

Abstract

Key findings • Mandelup[PBR] and PBA Bateman[PBR] were the fastest maturing varieties at Wagga Wagga. • Early sowing at both sites and water treatment (Wagga Wagga) prolonged the growth duration. • At Wagga Wagga, sowing date had no effect on biomass accumulation, however, more biomass was accumulated in the water treatment. • Early sowing increased biomass at Rankins Springs. • PBA Jurien[PBR] showed a high and stable grain yield over the 2 locations in 2021. At Wagga Wagga, it was the highest yielding variety, while at Rankins Springs only PBA Bateman[PBR] yielded higher. • PBA Jurien[PBR] and PBA Bateman[PBR] had the highest seed weight at Wagga Wagga, while Mandelup[PBR] and PBA Bateman[PBR] had the highest seed weight at Rankins Springs. • Machine grain yield increased with irrigation and late sowing.
