Maturity: Medium-Late (Optic type)
Drilling dates
Suitability for early drilling: Good
Suitability for late drilling (April): Good
Optimum drilling date: February to March (Scotland). January to February (England).
Recommended sowing rates
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.
Quench is a very adaptable and robust variety which suits many field situations. Syngenta trial results confirm that in good conditions there are no detrimental effects to Quench’s yield or grain quality by altering seed rates.
The table below shows the number of seeds per square metre that should be planted in good conditions. These figures should always be used in conjunction with the thousand grain weight of the seed.
Nitrogen application
On average over 50% of the spring malting barley that UK maltsters wish to purchase from England has grain N levels between 1.65 to 1.85%.
Varieties have different optimum nitrogen rates, therefore balancing N inputs to end market, variety and season is key.
Ensure you have checked levels with your contract and end market.
Syngenta nitrogen input timing trials have shown the following effects:
In most situations the recommended amount of N for Quench would be 125-150 kg/ha, applied by GS15. This advice is for guidance purposes only. You must work with your agronomist when calculating nitrogen rates and timings, taking into consideration end market requirements and the fertility of the field. You should also work within any Defra guidelines/restrictions.
