Barley irrigation and seeding rate locations
Aims

To investigate the irrigation water requirements of a barley crop and the impact that plant density, nitrogen (N), irrigation
intensity and waterlogging have on grain yield and quality, water use and water productivity.

Key messages

• In the wet winter of 2016, a single irrigation of a barley crop increased grain yield and grain quality but resulted in reduced water productivity.
• The 50 kg/ha seeding rate improved grain quality and reduced lodging compared with the 80 kg/ha seeding rate with no negative impact on grain yield.
• The waterlogged treatment (ponded for 48 hours) used an additional 0.41 ML/ha or 55% more water in one irrigation than the treatment that was ponded for only five hours.
