Winter Wheat Latest Safe Sowing Dates 2001
 | True winter wheats and barleys need a cold period to become
vernalised to make the change between vegetative and reproductive growth. |
| Many varieties can be sown in early spring with a
reasonable chance of success if ground conditions are satisfactory. The yield potential can be lower than spring varieties sown at the same time. |
| Although sowing after the latest safe sow date can
sometimes be successful - complete crop failure can occur if the ears do not develop. |
| Winter Oats do not need vernalisation - but sown
after 1st week March will be lower yielding and later maturing than spring varieties. Good for whole crop as gut fill - large yield - poor quality**. |
| Clients are advised to wait until ground conditions allow
safe sowing after Christmas - Jan - Feb. Check from the list below and sow at 1.5-2cwt per acre. If ear development is poor - whole crop by Mid July**. |
