Field experiment was carried out during 2012 and 2013 growing seasons at Al-Sidenawieh / Thi-Qar government to study the intraction between phosphorus and zinc and their effect on corn ( CV-106 ) yield and yield compontes .

Four P levels ( 0 , 60 , 120 and 180 kg P2O5 / ha ) as triple super phosphate and three zinc levels ( 0 .

5 and 10 kg Zn/ha ) as ZnSO4.7 H2O were used .

The results indicated that P and Zn application increased phosphorus and zinc concentration in the lower ear leaf .

Maximum yield was obtained when 60 Kg P2O5 and 5 Kg Zn/ha were used .

The result showed that increasing yield was mainly related to the increase to P and Zn applications.
