Effect of sowing date on grain yield of wheat—Wagga Wagga 2014

Abstract

Key findings • Flowering occurred approximately three weeks earlier than normal because of the warm autumn and winter. • Early flowering varieties in the first sowing date were badly affected by severe stem frosts. • Long season varieties had stable yields at all three sowing times. • Corack, Mace and Trojan had the highest grain yields in the second and third sowing dates. • Later flowering correlated with higher yield.
