Maize PR37K85

Stable grain yields for intensive farming

Selecting the PR37K85 hybrid from Pioneer s.a. is a strategic choice for operations focused on producing high-quality grain using intensive cultivation technologies. This simple hybrid with dent-type grain has established itself as a reliable asset in managing corn diseases and pests.

Phytosanitary control and resistance

A primary feature of PR37K85 is its high genetic resistance to a broad range of pathogens. Agronomists select this hybrid for fields with high infection pressure due to the following traits:

• Reliable protection against head smut and common smut.
• High tolerance to Helminthosporium leaf blight and stalk rot.
• Effective resistance against the European corn borer, significantly reducing losses during mechanized harvesting.

Planting and management recommendations

With an FAO rating of 90–1240 and a vegetation period of 160–180 days, this hybrid reaches its full potential in regions with a long, warm growing season. When planning the planting campaign, it is critical to maintain the optimal plant population density by harvest time:

• 55,000–60,000 plants/ha for regions with limited moisture or extensive farming practices.
• 60,000–65,000 plants/ha when utilizing intensive technologies and ensuring optimal mineral fertilization.

The dent grain structure ensures excellent dry-down properties, helping to minimize post-harvest drying costs while maintaining high-quality grain for market sale.
