  The Effects of Nitrogen Application on Robust Malting Barley

D.F. Walker1 and A.O.M. Smith11

Abstract: Six nitrogen fertility rates were applied to Robust barley to determine the response of yield, percent protein, lodging and other agronomic parameters. There was no significant difference in yield, however yields increased from 3.3 to 4.1 tonnes per hectare as nitrogen rates increased from 0 to 50 kilograms nitrogen per hectare and then declined from 4.1 to 3.5 as nitrogen rates were increased from 50 to 125 kilograms nitrogen per hectare. The was no significant response in Hectoliter weight and thousand kernel weight with increasing nitrogen rates. Both harvest lodging and plant height was significantly increased as nitrogen rates increased.
