Assessment of the application of gibberellins to increase productivity and reduce nitrous oxide emissions in grazed grassland

Emissions of nitrous oxide from grassland systems are attributable largely to the use of nitrogen fertilisers and the excreta deposited by grazing animals.

There is increasing interest in using gibberellins as a naturally-occurring growth promotant of herbage to reduce the use of nitrogen fertilisers while leading to similar or greater increases in dry matter.

In a study commissioned by the NZAGRC and carried out by Landcare Research, the conslusion reached is that the use of gibberellins with reduced addition of nitrogen fertiliser has the potential to reduce nitrous emissions from grazed grassland. However, acceptance of widespread use of gibberellins will be dependent on cost benefit analysis for farmers.
