Phosphorus fertilizer was applied at two rates to four soyabean varieties of different duration to maturity at four sites. The P rate had no significant (p > 0.05) interaction with site or variety. TGx1670-1F, one of the two late varieties, had the highest levels of total P (11 kg/ha) and apparent fertilizer P recovery (15%).
