Planting Density Optimization Boosts Maize Yield in North America

In North America, the optimal planting density has seen a significant increase of approximately 18,000 plants per hectare, resulting in a yield increase of 3.5 megagrams per hectare. The contribution of planting density to maize yield gain ranges from 8.5 to 17%. These findings are in accordance with a study published in the journal 'Nature Communications'.
