Intercropping soybean and fodder maize can increase productivity and land use efficiency. By adjusting the sowing schedule and maize harvest regime, researchers found that delaying maize sowing by 30 days after soybean planting resulted in higher yields. Harvesting maize at silage maturity (SM) increased herbage yield, while harvesting at green fodder maturity (GFM) led to higher protein content. The best approach for maximizing yield advantage and land use efficiency in this intercropping system is to sow fodder maize 30 days after soybean and harvest at SM.
