This experiment was conducted at the NSW DPI Leeton Field Station to test the response of two commercial soybean varieties and two numbered lines for potential release, to four target sowing densities.
• Averaged across sowing densities Djakal, N005A-80 and P176-2 yielded the highest with 3.7 t/ha, 3.8 t/ha and 3.9 t/ha respectively, while SnowyA achieved a significantly lower grain yield of 3.2 t/ha.
• Grain yield of Djakal and N005A-80 did not vary significantly between target sowing densities. Both varieties maintained high yields even at the lowest target sowing density (15 plants/m2).
• Lodging was exacerbated at higher sowing densities for all varieties except P176-2, which was consistently low across all sowing densities.
• The length of time to maturity did not vary significantly between target sowing densities for SnowyA, N005A-80 or P176-2. However, Djakal’s maturity length was extended by 4 days at the 60 plants/m2 sowing density when compared with the three lower target plant densities.
