Wheat response to pre-plant phosphorus at Safford Agricultural Center, 2001-03

The 2003 study was a follow up of the 2001 and 2002 studies, but the major differences were the selection of a high quality durum wheat with values significantly higher that those seen in the previous two studies and the untreated check was eliminated and a higher level of phosphorous was applied. Treatments applied were 100, 200, 400 and 600 pounds of 16-20-0 planted with the seed through the grain drill. Phosphorus applied at planting improved yields with increasing application rates. In this study, the highest rate of application of phosphorus produced the highest profit.
