To investigate the benefits of specialty phosphorus products and liquid phosphorus
options in cereals
There was no difference in wheat grain yield between the different phosphorus treatments in trial. The dry spring in 2007 resulted in considerably lower yields than expected due to a combination of severe frosts and moisture stress, delayed flowering and crop maturity. (There was substantial flowering “in the head” and failure of heads to fully grain fill.) There was also visual differences in growth across the trial (“patchiness”) that was evident in the high co-effeciency of variation (CV = 35.7).
