Very high yielding spring barley
Yield potential
POKER is a high yielding spring feed barley with good adaptation to Northern and Western regions in particular.
Source: HGCA Recommended List 2006. *HGCA RL Trials 2005.
Poker has produced excellent yields consistently across all regions of the UK, ensuring it is a reliable variety to grow.

Disease resistance
POKER has excellent resistance to mildew and good resistance to Rhynchosporium (6+), where it exhibits a different infection distribution from other HGCA Recommended Spring Barleys with good ratings (Doyen BRR-8 and Westminster BRR-5 ). Poker has also shown good tolerance to biotic and abiotic leaf spotting.

Fungicide use
Getting early to mid season agronomy right is crucial to establishing a healthy crop.
- T0 - The T0 spray prevents diseases gaining a foothold in long growing seasons or where disease pressure is high. The use of Unix helps keep Rhynchosporium at bay.
- T1 - Timing is key for protecting the canopy during the plants’ main burst of growth. Unix + Acanto provides broad spectrum disease control, but consider adding Morpholine or a triazole for curative Rhynchosporium control.
- T2 - Managing late season plant health is also vitally important to ensure a healthy harvest. This is the key time to protect grain fill with awns and green leaf areas being the key targets. Strobilurins protect against foliar diseases and Chlorothalonil has demonstrated control of biotic
Core fungicide programme
- T0 - Unix and Tern (should be used where mildew disease pressure is high)
- T1 - Acanto and Unix
- T2 - Amistar Opti + Triazole
Agronomic information
Poker is earlier maturing than Optic – 1-3 days earlier in England and up to 5 days in Scotland, therefore harvest management needs to take account of this accordingly.

Growth habit
- Early Spring: Semi-erect
- Tillering ability: Medium
- Maturity: Early
Drilling dates
- Suitability for early drilling: Good
- Optimum drilling date: February – March (Scotland) / January – February (England)
- Suitability for late drilling (April): Good
Recommended sowing rate
Seed rates are dependent on soil conditions at the time of drilling: the more difficult the environment the higher the seed rate must be to compensate for potential plant loss. The table below shows the suggested number of seeds per square metre that should be planted under good conditions.
The chart above should always be used in conjunction with the thousand-grain weight of the seed to calculate the sowing rate.
Nitrogen application
A split application is advised. 50% at leaf 1 and 50% 10 – 14 days later. Use high rates of nitrogen fertiliser to obtain yield return. As a guide, apply 10 – 15% more than Optic being grown for malting.
PGRs
Normally not required, however Syngenta Seeds advises the use on lush crops or very fertile sites. In these cases use low rate Moddus (0.1 – 0.2 l/ha) at GS 29-30 to stabilise tillers and promote root development.
Grain quality
Specific weight: 67.7
Sieving % through: 2.25mm - 3.0%
Sieving % through: 2.5mm - 7.9%
Harvesting priority
Normal priority – it is always advisable to harvest the crop in the best condition as soon as moisture is correct. Poker is earlier maturing than Optic and hence harvest planning should ensure Poker is harvested first.
