PORUMBEN 339 MV

Engineering Parameters of the Hybrid

Porumbeni 339 MV is a mid-early three-line hybrid developed by the researchers at the Porumbeni Institute for intensive forage production. The development focus for this cultivar was on balancing vegetative mass with cob nutritional value.

Biological Architecture and Potential

The plant structure, reaching 160–200 cm in height, ensures optimal stand density, allowing the development of a robust leaf apparatus without excessive light competition. Under field conditions, this translates into efficient PAR (Photosynthetically Active Radiation) utilization and dry matter accumulation.

• Maturation Phase: The development cycle lasts 100–110 days. This interval is critical for regions at risk of early moisture deficits in late summer, as it avoids extreme heat stress during the grain filling phase.
• Cob Morphology: A cob length of 18–20 cm, combined with the standard grain density for this hybrid type, guarantees a high grain fraction yield within the total silage mass. This significantly improves the energy density of the feed, providing a product with increased starch content—vital for cattle diets.
• Intended Use: The hybrid is optimized for fodder requirements. Its genetic potential enables consistently high yields of green mass, which possesses excellent ensiling characteristics due to the balanced sugar-to-protein ratio.

Practical Conclusion: Selecting 'Porumbeni 339 MV' is an efficient strategy for farms aiming to localize their feed production. High adaptability to the soil and climatic conditions of Moldova and neighboring regions helps minimize risks during high-quality silage preparation, securing a reliable energy source for livestock.
