Rainfall well below average left soybean planting in Goiás, Brazil, at under 10% of the area in October, compared with about 25% a year earlier. Because most local soybean cultivars need 105 to 115 days, the delay pushes back the harvest of the safrinha corn crop, whose ideal planting window closes in February.
Aprosoja-GO says producers are cutting corn area and expect lower yields.
A late soybean harvest squeezes the window for second-crop corn, which cuts Brazilian corn output and supports domestic and export corn prices. Feed buyers should expect firmer corn prices if the planting delays persist.
