The effects of phosphorus application on shoot dry matter and uptake of phosphorus, calcium and zinc in two wheat cultivars grown in a high clay soil

Abstract: Interactions of phosphorus (P) with calcium (Ca) and zinc (Zn) in different plant species have received a great deal of attention recently. A glasshouse pot experiment with different rates of P application (0, 30, 60, 90 and 120 mg P kg-1 soil) was conducted to investigate these interactions in two wheat varieties (Ege-88 and Gun-91). Increased application of P reduced shoot Zn concentration significantly. Shoot Ca concentration was also reduced by P application but the reduction was disproportionate to P application rate. These results demonstrate that P application could be one of the reasons for Zn and Ca deficiency. Therefore, the level of P application should be determined carefully in order to maximize yield.
