Abstract: (En)
In a field experiment in Western Australia, six levels of three different phosphorus (P) fertilizers (tripple superphosphate, TSP; Queensland (Duchess) rock phosphate, QRP; North Carolina rock phosphate, NCRP) were applied once only at the start of the experiment in 1984. Grain yield of triticale (x triticosecale) was measured from 1984 to 1988. In February-March after 1984, soil samples were collected to measure soil extractable P (soil test values) using four reagents (Bray 1, lactate, Truog and Colwe
