Opportunities exist to benefit from variation in yield and grain nitrogen percentage (N %) between spring barley varieties. Benefits include increasing yields and malting premiums, as well as adjusting N fertiliser according to variety.

Yield, grain N % and N offtake were measured in eleven varieties at ten sites across Scotland, at harvest 1997. A linear regression was done for variety yields against the mean yield of all varieties (or site yield). Site yield was an indicator of site yield potential. The extent to which each variety responded to changes in site yield potential was determined by its sensitivity score i.e. the slope of the linear regression. Regression analyses were also done for grain N % and N offtake.
