Maize RT 47 SV

Genetic Potential and Adaptability of the RT 47 SV Hybrid

The RT 47 SV corn hybrid from Agroplazma is a technological solution for intensive farming, aimed at achieving stable, high grain yields. As a mid-to-late maturing hybrid, it requires precise planting schedule planning based on local climate patterns and the required heat unit accumulation.

Morphological Features and Grain Type

The core characteristic of the RT 47 SV is its dent (teeth-like) grain type. This feature enhances harvest efficiency: the dent structure promotes faster moisture release, significantly reducing post-harvest drying costs. The ear is optimized for effective starch accumulation during the late vegetative stage.

Defense Mechanisms and Phytosanitary Stability

Agroplazma’s engineering approach for the RT 47 SV focuses on minimizing phytosanitary risks. The hybrid’s genetic architecture provides significant resistance to:

• Corn Fusarium, which is crucial for grain storage quality.
• Common Smut, helping to prevent losses in marketable yield.

These features reduce the need for excessive fungicide applications, allowing the plant to direct its energy toward reproductive growth rather than disease management. The hybrid also displays tolerance to a complex of diseases, including Helminthosporium leaf spot and stalk smut.

Planting Density Recommendations

The yield performance of the RT 47 SV depends heavily on managing planting density. The manufacturer recommends a tailored approach:

• In high-productivity or irrigated fields, the optimal density is 65,000–75,000 plants/ha.
• In moisture-limited areas, it is recommended to reduce density to 55,000–60,000 plants/ha to mitigate intraspecific competition for water.

Adhering to these density protocols ensures the full potential of this mid-to-late hybrid is realized and helps prevent lodging during grain fill.
