FAQs for PAC 500

Comparative Relative Maturity (CRM) is a standardised measure used to compare how long it takes different corn hybrids to reach physiological maturity—specifically, when the grain reaches black layer.

PAC 500 has a CRM rating of 111 days*, which places it in the medium maturity category. This means it takes longer to mature than quick-season hybrids, making it a strong choice where longer growing windows allow for maximising yield potential.

*Although CRM is expressed in “days”, it’s not a literal count of calendar days. Instead, it reflects a relative measure based on accumulated heat units (growing degree days or GDDs) under standardised conditions. So, a 111 CRM hybrid like PAC 500 typically matures later than hybrids with lower CRM values, but the actual number of days to maturity can vary by environment.

PAC 500 has a moderate to high level of stay-green, helping it maintain leaf area for longer during grain fill. This supports yield potential under moisture stress, provides flexibility around harvest timing, and contributes to overall crop resilience in tougher seasons.

PAC 500 has excellent grain dry-down, allowing for timely harvest and reduced reliance on artificial drying. This helps lower harvest costs and manage logistics more efficiently, especially in high-yielding or late-planting situations.

A general recommendation is to plant between 80,000 and 90,000 seeds/ha. However, the ideal population depends on your paddock conditions, seasonal outlook, and management approach. For the best result, consult your agronomist or Pacific Seeds technical staff to tailor a planting rate that suits your farm.

No — PAC 500 is not part of the Imidazolinone Tolerant (IT) range, so IMI herbicides should not be used on this hybrid.

If you require IMI tolerance, look for any of our hybrids with ‘IT’ at the end of their name — these are specifically bred to tolerate registered IMI herbicides.

PAC 500 is a versatile hybrid suited to feed grain and silage. It delivers strong grain quality and yield for livestock feed and export buyers, while also offering good whole plant characteristics for silage production.
