Maize Weber

Engineering profile of the Weber hybrid

Developed by the Institute of Grain Crops of the NAAS, Weber is a late-maturing simple hybrid with a strong emphasis on biomass and grain productivity. Its genetic architecture is built on adaptability to intensive farming conditions, where the balance between the vegetation period and dry matter accumulation potential is critical.

Technical specifications and morphology

• FAO and life cycle: The FAO range of 90–1240, combined with a 160–180 day maturation cycle, classifies this hybrid as late-maturing. This requires precise sowing timing to ensure the grain filling cycle completes before the first frosts.
• Grain structure: The dent-type kernel ensures high processability during threshing and drying, as well as optimal conversion in silage mass for fodder production.
• Plant density: Optimal plant population parameters range from 45,000–50,000 plants/ha (under moisture-stressed conditions) to 55,000–60,000 plants/ha (to ensure maximum yield under intensive farming practices).

Phytosanitary potential

A key advantage of Weber is its high level of natural resistance to common smut (Ustilago maydis). This genetic protection minimizes the risks of reproductive organ deformation, which is vital during the long vegetation period. The hybrid also demonstrates stability against stalk rot pathogens, which expands its utility in complex crop rotation schemes.

Application recommendations

Its dual-purpose nature—grain or silage—makes this hybrid an essential tool for farms with diversified production. The extended vegetation period contributes to the formation of a massive leaf-stem apparatus, guaranteeing high energy values for silage. When harvested for grain, the hybrid requires careful monitoring of moisture levels due to its late maturation characteristics, although the potential yield effectively offsets the logistical challenges.
