Phosphorus recovery from triple superphosphate by soyabean in the Guinea savanna of Nigeria

Ogoke, I.J., Togun, A.O., Carsky, R.J. & Dashiell, K.E. (2006). Phosphorus recovery from triple superphosphate by soyabean in the Guinea savanna of Nigeria. Tropical Science, 46(3), 129-133.

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%).
