In addition, if the root system can absorb nutrients efficiently, it will also drive the leaves and stems to grow together, and the whole plant can accumulate more biomass. This synergy between aboveground and belowground growth is an important mechanism in maize growth (Borrás and Vitantonio-Mazzini, 2018; Ibraheem and El-Ghareeb, 2019). Figure 1 Root scan map.

Global studies have shown that if the planting is denser, the total yield of corn can be increased by about 11.2%. This is mainly because during the period from seedling to heading, the dry matter accumulated by corn increased by 22.9%, and the efficiency of transferring dry matter to grains also increased by 12.6% (Shao et al., 2024). Planting densely can better utilize sunlight, which is conducive to the rapid growth and high biomass of corn in the early stage, but the yield per plant and root growth may be reduced. To solve this problem, you can choose compact varieties and arrange the density reasonably, so that you can plant more and not affect the light (Shao et al., 2024; Lei et al., 2025). Another effective method is to properly trim the top leaves, such as cutting off the top two leaves. This allows the lower leaves to get more sunlight, is not easy to age, and has better photosynthesis. Studies have shown that after such treatment, grain yield can be increased by 13% to 19% (Raza et al., 2019). Different regions have different climates and soils. It is best to adjust the density according to local conditions, and then combine it with precision irrigation and scientific farming to maximize the yield (Lei et al., 2025).
