In a global analysis, researchers found that for maize yield to reach a breakthrough from 1.0 to 25.0 Mg per hectare, it was necessary to have a large but not excessive maximum Leaf Area Index (LAI) of 6.74 at the silking stage, as well as a relatively large LAI of 3.35 at maturity. These conditions were essential for achieving dense planting.
