Nitrogen timing and sowing date in barley locations
  • To improve the nitrogen use efficiency of malt barley by manipulating canopy size and structure by application of nitrogen at different timings across the growing season.
  • To establish the link between sowing date and nitrogen timing in new malt barley varieties in order to maintain yield and quality.
  • To assess the value of using optical crop sensors in aiding nitrogen management.
Key messages
  • Later applications of nitrogen (GS30 & GS37) were the most profitable with the highest yield and quality, for malt barley in 2010.
  • There was no significant differences in yield of varieties between early and later sowings.
  • Crop sensors provide a good measure of nitrogen response and can improve nitrogen use efficiency.
