Maize DK 243

Technical Overview: The Monsanto DK 243 Hybrid

The DK 243 maize hybrid from Monsanto is engineered for high-intensity grain production, prioritizing structural uniformity and reliable yield stability. By utilizing a simple hybrid architecture, Monsanto has achieved high plant-to-plant consistency, which is a significant advantage for precision farming and automated harvesting processes.

Agronomic Profile and Efficiency

With an FAO rating of 240 and a maturity cycle of 100–110 days, this hybrid is well-suited for regions requiring rapid development to beat the end-of-season moisture limitations. The flint-dent grain texture serves as an optimal technical compromise: the flint component enhances early-season cold tolerance and stalk strength, while the dent portion ensures superior drying kinetics during the final stages of maturation.

• Seeding Density: Recommendations range from 65,000–70,000 plants/ha in moisture-stressed environments to 70,000–80,000 plants/ha under optimal water availability. Adhering to these density parameters is essential for maintaining proper cob development and ear size.
• Application: Optimized exclusively for grain production, with a focus on maximizing starch accumulation in the endosperm.

The practical value of DK 243 lies in its agronomic plasticity. Its shorter vegetative period allows the crop to effectively utilize moisture during the early summer, effectively bypassing late-season environmental stresses. The simple hybrid nature minimizes phenotypic variability, ensuring that crops reach maturity at the same time, which simplifies harvest timing and reduces grain damage during the threshing process.
