VSAP: Canola - Irrigation Frequency - Leeton - Murrumbidgee Valley
Published: 20 Feb 2018
- One spring irrigation achieved maximum canola grain yield on a self-mulching clay soil.
Although little rainfall was received in spring, the soil moisture profile was full during winter.
- Hyola® 559TT yielded higher than Hyola® 577CL in all irrigation treatments due to a higher
- Nitrogen rate and timing did not affect canola growth and grain yield regardless of irrigation
One of the more difficult decisions irrigation growers have to make is deciding where to use their irrigation water to get the best returns. Growers often face the dilemma of having an established winter canola crop in the ground and not knowing whether to give it one or more spring irrigations or to save the water for use on a summer crop. With water availability at a premium it is important to know if water required for an additional spring irrigation could be better utilised elsewhere.
In 2014, an experiment at Leeton in the Murrumbidgee Valley of NSW investigated spring irrigation water requirements of canola grown following wheat. The impact of four irrigation intensities and four nitrogen rates on grain yield and quality, water use and productivity was investigated.
