Maize yield

Zea mays L. subsp. Mays

Maize yield is a key trait evaluated separately for grain and silage purposes. It is determined as the result of the interaction between the hybrid's genetic potential, maturity group (FAO), plant density, and agro-technological environmental conditions.

In the reference 5 varieties crop Corn, where this is mentioned in the description.

Maize grain yield indicators are measured in t/ha or dt/ha at standard moisture content, whereas for silage mass, the critical parameter is dry matter yield. The biological productivity potential of a plant is calculated through yield structure components: the number of grain rows per ear, the number of grains per row, and the thousand-grain weight (TGW).

In variety trials and production, maize productivity is limited by plant density, where excessive thickening above 70–80 thousand plants per hectare can reduce the return from each individual specimen. The realization of a hybrid's potential directly depends on the FAO maturity group and the availability of heat and moisture for the crops, which makes yield assessment dependent on the soil-climatic zone and cultivation technology.
