Onion (Allium cepa) is a horticultural species grown both for fresh consumption and industrial processing. It prefers fertile, well-drained soils rich in organic matter. The crop cycle varies from spring to autumn depending on variety and growing area.

Yield and quality depend on varietal choice, irrigation management, nutrition and pest control. Key quality traits assessed in the final product include size, uniformity, firmness and dry matter content.

Vegetative Development

During the early growth stages of onion, balanced vegetative development is crucial to ensure rapid canopy coverage, increase leaf photosynthetic surface and maximize assimilates production destined for bulb formation. Factors such as water imbalance, thermal stress or nutrient fluctuations can slow growth, compromising early vigor and crop uniformity.

PHYLEN®, thanks to its formulation combining nutritional components and anti-stress agents, supports vegetative development, promotes vigorous and uniform plants and helps prevent growth stoppages due to adverse conditions. This enables onions to develop fully, producing healthy, uniform bulbs of high commercial quality.

Environmental Stress for Onion

Environmental stresses can slow vegetative development and hinder bulb enlargement, compromising crop uniformity and yield. Extreme temperatures, drought, wind or intense light are among the most impactful factors affecting balanced onion growth.

Under these conditions, application of FYLLOTON® is particularly effective. Rich in amino acids and plant extracts, it stimulates vegetative development, supports plant resilience and promotes uniform, vigorous bulbs of high commercial quality, ensuring maximum productive potential throughout the crop cycle.

Yield and Quality for Onion

During bulb enlargement, the main goal is to obtain well-balanced plants able to efficiently convert leaf-produced assimilates into bulb tissues. Activating and supporting these mechanisms is fundamental to achieving high yields, uniform bulb size and good commercial quality, key factors for market requirements and economic return.

Foliar application of RIZAMMINA® 42 supports optimal bulb development. Thanks to its amino acids and macro/microelements, it stimulates cell division and improves photosynthetic efficiency, promoting assimilates flow toward the bulb. This helps increase both total yield and qualitative characteristics of harvests.
