In sandy loam soil soybean plants cv Crowford were soil fertilized with 60 kg P2 O5/ fed in the form of either superphosphate, or triple phosphate or ammonium diphosphate and foliar sprayed with Zn or not. Foliar spraying of Zn markedly increased protein content, Mn, Zn as well as oil content of soybean seeds except of phosphorus content which was markedly depressed by Zn spraying. Moreover, different phosphatic fertilizers increased protein-N Mn, Zn, P and oil content in soybean seeds.
