The project aimed to look at the impact of autumn irrigation in establishing canola plant population and increasing biomass.
The 2021 season was a wet winter which allowed for optimal growing conditions and did not allow for the “winter drought” environment to exist.
We noted that there was no difference between the Autumn waterings on the overhead system.
There was a yield decrease in the area that had water applied in the surface system. The area that was watered had a yield impact due to the water logging of the soil.
The ability to apply a smaller amount of water with the overhead allowed the crop to not be negatively affected compared to the surface which logged the soil and impacted yield potential.
Growers look at the long-range forecast to decide if they should apply water in their surface system, growers utilise the control of their overheads and water up canola to ensure sufficient establishment of canola.
Grower to water one bay of Canola in the autumn and leave one bay not watered in the autumn. All crop treatments to be the same and watering in the spring to be the same across both areas.
