Maize Yield

Zea mays L. subsp. mays (Maize Group)

Maize yield is an integral quantitative indicator of a hybrid's productivity, measured in centners or tonnes per hectare, which depends on genetic potential, stand density, mineral nutrition, and weather conditions.

In the reference 692 varieties crop Maize, where this is mentioned in the description.

When assessing yield in the field, the number of productive plants per unit area, the degree of ear kernel set, and the thousand-kernel weight are taken into account. Final calculations in variety trials are conducted by harvesting plots followed by adjusting grain weight to a standard moisture content, which is a critical evaluation factor.

Modern hybrids are capable of reaching 13–18 t/ha under high-input management, whereas yields can drop below 2 t/ha under stress conditions. The final result is decisively influenced by the choice of a hybrid with an appropriate maturity group on the FAO scale, as well as the optimization of seeding density.

A deficiency of moisture and nutrients, especially nitrogen and phosphorus, during critical development phases such as flowering and grain filling, directly determines grain weight. A lack of moisture during the tassel emergence period can reduce potential yield by more than 40%.
