DKC 4490

Genetic Potential and Grain Structure

The DKC 4490 hybrid by Monsanto is a specialized solution for high-productivity maize cultivation, focused on maximizing starch yield. Technically, the model belongs to the mid-early maturity group, offering flexibility for farms targeting optimal harvest windows. The foundation of its biological productivity is the dent-type grain with a 72% starch content, positioning this hybrid as a high-energy raw material for both commodity grain and high-quality silage.

Phytosanitary Resistance and Crop Protection

Monsanto's engineering in the DKC 4490 is aimed at minimizing harvest losses during the ripening stage. Its agronomic profile includes complex resistance to pathogens that critically affect grain quality:

• Disease Resistance: The hybrid features pronounced resistance to Helminthosporium leaf blight, Fusarium, and head smut, which reduces the need for heavy fungicide application and preserves cob integrity until harvest.
• Smut Protection: Selective breeding ensures a strong immune response against common smut, preventing malformed cobs and ensuring consistent grain filling.

Agronomic Seeding Parameters

Realizing the potential of DKC 4490 depends on plant density, which should be adjusted based on regional moisture availability:

• In well-irrigated conditions, a density of 65,000–70,000 plants/ha is recommended.
• Under average moisture conditions, the optimal range is 60,000–65,000 plants/ha.
• In arid regions or under extensive farming practices, the rate is reduced to 50,000–60,000 plants/ha to allow plants to efficiently utilize available soil resources without excessive nutrient competition.

Its dual-purpose application (grain and silage) makes this hybrid a versatile workhorse for mixed-farming operations. With a high thousand-grain weight and rapid dry-down, DKC 4490 demonstrates stable yield metrics even during unstable weather conditions in the latter half of the growing season.
