There was a strong early visual response to applied phosphorus (P), with the nil P plots lacking vigour early. This was confirmed with significantly better P levels in the plant tissue up to 35 kg of P applied see There was no significant response to applied copper, zinc or sulphur. There was a significant yield response to applied P, however at the highest rate of applied P the yield began to fall. This is possibly due to the increased dry matter produced using more moisture and as a consequence of the dry finish in November losing some yield potential. In this situation the most appropriate rate of applied P for this year would have been between 15 - 20 kg P/ha.
