In a green-house experiment with rice conducted to study the zinc-phosphate interrelationship in a submerged alluvial soil, P and Zn fertilization either alone or in combination significantly affected the yield and the concentration and uptake of P and Zn by rice crop. The concentration of Zn and P decreased significantly with increasing levels of P and Zn, respectively. The antagonistic effect of P on Zn was more pronounced than that of Zn on P. The effect of P×Zn interaction was significant on Zn availability in soil which indicates that the availability of applied Zn reduced in presence of P.
