Sum16-28 Potassium Strategies, Darkan

AIM:

To assess the value of different muriate sources of potassium (K) on growth and yield of oats when applied by banding and topdressing at seeding time or topdressing after emergence.

For further details contact your local Area Manager or the Summit Research Team

**Fig 1:** Yield and hectolitre weight in oats in response to K

**Fig 2:** Average response to K rates and timing.

CONCLUSION:

Under these conditions, applying 15kg/ha of K appears to be the best option to optimise yield and maintain soil K levels without decreasing returns.
