Evaluation of new soybean varieties for the Macquarie Valley – Trangie Agricultural Research Centre, 2013–2016

Abstract

Key findings •• Soybean yield potential ranged from a low of 1.01 t/ha up to a high of 2.94 t/ha in two years of harvested irrigated variety evaluation experiments at Trangie in the Macquarie Valley. •• Delayed sowing of a soybean crop in the Macquarie Valley can increase the likelihood of delayed maturity, potentially running into prolonged periods of wet autumn weather at harvest time; the 2015–16 experiment was not able to be harvested for this reason. •• Moonbi[PBR] (released 2010) is the recommended variety for Macquarie Valley soybean growers under fully irrigated conditions. It has high yield potential, maturity adaptation, excellent grain quality to meet human consumption markets, and resistance to powdery mildew. •• Djakal (southern NSW variety) is recommended for partial irrigation or dryland situations. Its earlier maturity and lodging resistance due to shorter height and reduced biomass enables it to achieve high yields and human consumption quality under less favourable growing conditions.
