Winter Barley

Nitrogen recommendations for Winter Barley based on soil N index and crop yield potential (kg/ha)*
Soil N Index	8.5	9.5	10.5
1	180	200	220
2	155	175	195
3	120	140	160
4	80	100	120
To convert kg/ha to units/ac multiply by 0.8

* Proof of higher grain yields is required for an additional 20kgN/ha for each one tonne above a base grain yield of 8.5t/ha.

* Higher grain yields shall be based on the best yield achieved in any of the 3 previous harvests, at 20% moisture content.

Suggested N Programme for 9.5t/ha winter barley on soil N index 1

Crop Type*	Mid-Tillering (early March)	GS 31/32 (early April)	GS 31/32 (10 days later)
Winter Barley (200kg N/ha)	60kg/ha	100kg/ha	40kg/ha

* Adjust N rates / timings based on soil type and previous experience

* Complete N applications by GS 32

P & K Advice for winter barley based on different crop yields (kg/ha)

To convert kg/ha to units/ac multiply by 0.8 * Higher grain yields shall be based on the best yield achieved in any of the 3 previous harvests, at 20% moisture content. *Where pH is greater than or equal to 7, 20kg P/ha may be applied on soils at phosphorus index 4.

Always adjust nutrient applications where organic manures are applied
