Saroon-houco experiment was condunted using a Zn deficient Typia Torripeam-ments to study effect of P and Zn sources and their levels on their relationship in maize, using DAM, MCP and SSP (50 and 250 ppm ) as source of and Zn50,. R-Zn and ZnO (0 and 50 ppm Zn) as source of Zn. MCP and DAP at 250 ppm P depressed the vield, while SSP enhanced it. Zinc concentration was decreased in shoot and root both, when MCP and DAP were used as Psources with ZnO. The urder of Zn sources in increasing Zn content of shoot was Z1304 71120 = R-Zn/Zno. The efficiency of ZnO and R-Zn was generally enhanced when applied with SSP, whereas, at other two P sources ZnSO, was the best source, Root and shoot Pincreased with P application and MCP was more efficient than DAP and SSP as far as utilization of P by plants was concerned. Zinc decreased P concentration and doorcoso was moro in shoot than root, Under Zn deficient conditions Poon centration in shoot was much higher than applied Zm
