Aims

Assess the performance of durum grown at different plant populations under overhead irrigation

Key messages

• Yield was below expectations which appears to be due to inadequate soil moisture in late winter, with irrigation not possible due to the irrigation season being closed.

• Establishment rate for the trial averaged 76% but was lower at the highest populations.
• There were differences in biomass at GS30, with the trend to lower biomass at lower • seeding rates and this was reflected in shoot numbers.
• Yield was not influenced by seeding rate in either variety, although plant populations below 100plants/m2 tended to be the lowest yielding, however there was little or no difference in grain yield between 150 – 240plants/m2.
• Yield was below expectations which appears to be due to inadequate soil moisture in late winter, with irrigation not possible due to the irrigation season being closed.
• Winter drought is a risk that is greater under overhead irrigation as the soil profile is unlikely to be full at the beginning of winter as is the case under flood irrigated circumstances.
• Water use efficiency was 16.1 kg/mm
