September vs October Drilling: Balancing Risk and Reward

In this episode of Tramlines, inspired by a conversation with our very own customer James Peck from PX Farms, we are joined by Agrii agronomist and technical advisor Craig Simpson to explore one of the most debated topics in arable farming: when is the right time to start drilling winter crops?

With an early harvest tempting growers into the field, Craig examines the yield benefits of early September drilling alongside the increased risks from grass weeds, BYDV and disease pressure.

Together, they discuss how farmers can balance risk and reward to maximise crop performance in an increasingly unpredictable climate.

Key Takeaways:

• Early drilling can boost yield potential through stronger establishment, greater tiller numbers and improved rooting, helping crops cope with dry spring conditions.
• Delaying drilling can significantly reduce grass weed pressures such as blackgrass and sterile brome, improving long-term weed control. 
• September-drilled crops face higher BYDV risk, with warmer conditions and increased aphid activity potentially adding further pressure this season. 
• Earlier drilling can increase disease risk, particularly septoria, as denser canopies allow disease to build more rapidly during wet seasons.
• The best approach is a planned, field-by-field strategy, considering weed burden, variety selection, disease resistance and local conditions before drilling begins. 

October drilling? 

Success starts with choosing the right seed for the right timing.
