To assess the effects of plant growth regulants (PGR’s) on crop growth and grain yield across variable soils in barley.
Yield differences between treatments were highly significant. Differences observed between the growth regulant treatments and nil were up to 0.5t/ha along the trial strip. The yield differences were not significant at the northern end of the trial strips, this is where localised waterlogging was observed in the trial and crop growth was reduced before the growth regulants were applied, as observed in the crop spec data.
