Effect of sowing date on irrigated soybeans in southern NSW 2015–16

Abstract

Key findings •• For all varieties, the middle sowing date (4 December) resulted in higher grain yields than the early (11 November) or late (23 December) sowing dates. •• Varieties, N005A-80 and Bidgee[PBR] consistently achieved the highest seed protein concentrations. •• Varieties, Snowy[PBR] and Bidgee[PBR] achieved consistent seed protein concentrations across the three sowing dates, while later sowing dates reduced the seed protein of Djakal, N005A-80 and P176-2 varieties.
