DKS 5143

Genetic Potential and Grain Structure

DKS 5143 by Monsanto is a classic single-cross maize hybrid designed exclusively for grain production. The key feature of this germplasm is the dent grain type with a high starch content (72%). Physiologically, this translates into a high rate of moisture loss during maturation, which is critical for reducing post-harvest drying costs.

Phytosanitary Resistance as a Crop Protection Tool

Resistance to pathogens in the DKS 5143 hybrid is achieved through comprehensive breeding programs. Special attention is paid to three major threats to maize crops:

• Fusarium Ear Rot: A strong immune response reduces the risk of mycotoxin development, which directly impacts grain quality and market value.
• Common Smut: Genetic protection allows for cob integrity even under stress conditions during the vegetative period.
• Stalk Rots: High tolerance ensures stalk strength, minimizing losses from lodging, which is a critical factor for mechanized harvesting.

Planting Density Recommendations

When adapting the hybrid to specific field conditions, it is essential to consider the planting density, which directly affects ear development and potential yield:

• Under favorable moisture conditions and on fertile soils, the optimal density is 65,000–70,000 plants/ha.
• In water-limited zones or on soils with low moisture-holding capacity, it is recommended to reduce the rate to 55,000–60,000 plants/ha.
• Moderate densities (60,000–65,000 plants/ha) are optimal for temperate climates with predictable precipitation.

A maturity period of 110–120 days allows for the efficient use of the growing season while minimizing the risk of early frost exposure. Monsanto's technological solution in this hybrid is aimed at maximizing productivity potential through strict adherence to best agronomic practices.
