Maize CODEXA

French genetics in the field: operating the «Codex» hybrid

When selecting seeds from Maisadour Semences, farmers look for consistency and reliability. «Codex» is one of those hybrids that meets expectations for both yield and ease of management.

Agronomic performance and plant health

The 110–120 day maturity window allows for effective harvest planning. Its resistance to common smut is visibly excellent, with ears remaining clean even under high humidity levels. The plant's natural defense against fusarium and stalk rots is a significant advantage, particularly in wet autumns, as it reduces the need for heavy fungicide applications.

Seeding density and management

• 80–85k plants/ha is ideal for maximizing grain weight in standard moisture conditions.
• 90–95k plants/ha is justified in highly fertile soils with intensive feeding, where the hybrid maximizes silage biomass production.

The dual-purpose nature of «Codex» (suitable for both grain and silage) makes it a smart inventory choice for any farm. It is a forgiving hybrid that performs well under varied agronomic practices, ensuring stability and protecting against major crop diseases.
