Abstract :
Phosphorus (P) and Zinc (Zn) are the essential elements for plants that have various effects on different plants. In order to study of P and Zn interactions on soybean, a pot experiment was conducted as factorial trial was arranged in a completely randomized design with three replications in 2011. Factors tested included three levels of P (0, 50 and 100 mg.kg) of Triple super phosphate, three levels of Zn (0, 5 and 10 mg.kg) of zinc sulphate. Mean comparisons of P effect showed that leaf and seed P concentration significantly increase and leaf and shoot Zn concentration significantly decrease with increasing of P levels, but had no significant effect on seed protein and seed Zn concentration. Maximum seed oil was obtained in 50 mg.kg P level. Mean comparisons of Zn effect showed that leaf, shoot and seed Zn concentration significantly increase and seed P concentration significantly decrease with increasing of Zn levels but had no significant effect on leaf P concentration, seed protein and seed oil. The highest P concentration in the seed was obtained with 100 mg.kg P and 5 mg.kg Zn treatments and the highest zinc concentration in the seed was obtained with 50 mg.kg P and 10 mg.kg Zn treatments. In conclusion, interaction of these elements had various effects on quality characteristics of soybean and balance Application of P and Zn in soil increases of these elements and oil in plant.
