Cultivation
Zea mays L.
The maize seeding rate is focused on achieving the target plant density at harvest, taking into account the compensatory properties of hybrids and biological competition for resources.
In the reference 44 varieties crop Maize, where this is mentioned in the description.
Maize possesses a pronounced ability to compensate for sparse planting density by increasing the mass and number of kernels per cob. The optimal density for modern hybrids typically ranges from 60,000 to 90,000 plants per hectare, with exceeding the 80,000–90,000 threshold leading to unnecessary competition for light, moisture, and nutrients, thereby reducing resistance to lodging.
When calculating the seeding rate, key factors include the moisture availability of the growing zone and the morphological characteristics of the hybrid, such as stem height and maturity group. It is critically important for the crop to achieve uniform emergence with a difference in development of no more than two days, as lagging plants are unable to catch up with their neighbors and form significantly smaller cobs, effectively becoming intraspecific weeds.
Cultivation technology requires focusing on the target density at harvest rather than the thousand-kernel weight. Realization of the genetic potential directly depends on the precision of the seeders: the presence of skips or 'doubles' during sowing negates the effect of a properly selected seeding rate.
