Gross margin analysis: spring planted soybean variety Gwydir[PBR], Codrington 2021–22

Abstract

Key findings •Gwydir[PBR] soybean variety was planted in spring (5 October 2021) and harvested on 23 March 2022, yielding 4.6 t/ha. •The total crop gross margin was $1738/ha, based on a grain price of $600/t. •Above average rainfall during the growing season (including a major flood event before harvest), resulted in the grain being downgraded due to weather damage from resulting in a lower grain price. •In coastal NSW, spreading planting dates is advantageous to spread the risk of crop loss due to extreme weather events. •Planting, Gwydir[PBR] in early spring resulted in a longer vegetative phase, compared with traditional planting dates of early December, however, this did not result in greater plant biomass, plant height or excessive lodging.
