Maize productivity

Zea mays L. subsp. mays (Maize Group)

A complex indicator of a maize hybrid's ability to produce grain or biomass, determined by its genetic potential and its realization under specific cultivation conditions.

In the reference 123 varieties crop Maize, where this is mentioned in the description.

Maize productivity is composed of quantitative yield structure elements, including the number of productive plants per unit area, the number of ears per plant, grain weight per ear, and 1000-kernel weight. The final indicator is expressed in tonnes or centners per hectare, and for green mass, in terms of fresh or dry matter weight.

Productivity assessment is carried out in field trials by comparing it with a standard variety zoned for a specific region. Yield depends heavily on the maturity group according to the FAO index and cultivation technology: under unfavorable conditions, it ranges from 10–20 c/ha, while intensive hybrids can reach 80–150 c/ha.

The realization of productivity potential depends directly on plant stand density, the level of mineral nutrition, and moisture availability. When selecting hybrids, an agronomist correlates the yield potential with the crop's requirements for the sum of active temperatures, taking into account the stability of productivity over the years under stress conditions.
