Corn Plant Population

Zea mays L.

Corn plant population is a key yield factor determined by hybrid genetics, FAO maturity group, moisture availability, and mineral nutrition level.

In the reference 485 varieties crop Maize, where this is mentioned in the description.

For corn, the plant population metric is closely linked to the intended use of the crop: planting density is lower when grown for grain compared to green forage, where excessive crowding can lead to a decrease in the proportion of ears. Optimal parameters depend on the morphological characteristics of the hybrid, including plant height, degree of tillering, and the ability to form multiple ears.

Under moisture-deficient conditions, plant population should be reduced to minimize competition between plants for soil resources and prevent water stress. In high-fertility conditions with adequate moisture, plant density is increased to more fully realize yield potential, taking into account the photophilous nature of corn and the risk of productivity decline due to shading from excessive crowding.
