Research and industry data in Argentina have highlighted the economic and yield benefits of optimizing planting densities for maize and sunflower crops.

Nidera Semillas reported that variable maize planting density can increase economic returns by an average of US$52 per hectare, reaching up to US$85 per hectare in high-productivity environments. Since 2020, this method has produced yields approximately 4.5% higher than uniform management.

Complementary research from the National Institute of Agricultural Technology (INTA) identified specific optimal densities. In the Junín region, sunflower trials found that 47,700 plants per hectare yielded higher profit margins than lower or higher density alternatives. In San Luis, maize trials under rainfed conditions showed that increasing density from 5 to 8.5 plants per square meter increased average yields by 27%, though researchers noted this was contingent on favorable water availability during critical growth stages.
