Practicing best nitrogen management in rice

The C19 Rice crop saw some variable yield results, some of these can be related to nitrogen management. Part of this was due to:

  • Insufficient or excessive nitrogen rates applied

  • Change in application methods resulting in increased nitrogen efficiencies i.e. going from broadcast onto the surface to drilled 7-10 cm below the soil surface

  • Nitrogen applied at the wrong time

  • Inaccurate spreaders causing stripes in the crop

Case study - A change to drill sowing produces a record yielding Doongara crop

April and Robert Andreazza of Wilbriggie, C19 Doongara crop (41 ha) yielded 14.0t/ha (1.18t/ML) and is the highest Doongara crop on record. Robert drill sowed for the first time in his C19 crop to make the most of the small water allocation year with reduced hectares from his usual rice program. He was curious to see if there were benefits in drill sowing, and saw the opportunity of a reduced rice program in spending additional time to ensure changes in practice would be spot-on. The resulting record high yield is testament to his successful transition to drill sowing allowing him to capitalise on a perfect run of weather during the reproductive period.

Getting the most out of nitrogen and irrigation in a tight year

As crops approach mid tillering, it is time to start considering crop nitrogen requirements for topdressing. Many winter cereal crops this year will be grown on rice stubble, so there will be little nitrogen available without topdressing. Yet in a year with minimal water availability and a dry seasonal outlook, your nitrogen topdressing requirement should be determined by how much water you have available to finish off your crop, current soil moisture status and likely returns.
