Phosphorus nutrition in canola at Caroona, Mullaley and Garah in 2013

Abstract

Key findings • There was no impact of varying phosphorus rate on plant establishment at any of the three trial sites. • There was only a significant difference in dry matter production at the Mullaley site, but this was not consistent with increasing phosphorus application rate. • There was no effect of varying phosphorus rate on final grain yield or oil content at all three trials sites, across a range of quite low final yields, from 0.5 – 1.4 t/ha. • Pioneer®44Y84 had better establishment than HyolaR559TT, however, the grain yield was only significantly better at the Caroona trial site.
