Updating nitrogen and sulphur fertiliser recommendations for spring barley.
The spring barley area is now expanding onto heavier land, a consequence of Blackgrass control strategies, which is likely to affect the optimum nitrogen (N) strategy to achieve the various grain N% targets.
Modern varieties are significantly higher yielding, suggesting that they may require more N to achieve potential yield.
There’s a lot of industry uncertainty about optimum N applications. It’s also unknown how sulphur (S) fertiliser affects the grain N% of modern spring barley varieties.
LIMAGRAIN UK INVOLVEMENT
We’re very pleased to be involved with this project, as our own trials have shown that yields of new varieties can be improved significantly with the application of additional nitrogen, without compromising target grain N%.
This project will provide a better understanding of how N rates, N timings and S rate should be managed for maximum yield and targeted grain N%.
