A pot experiment was conducted in the green house of College of Education/ Scientific Departments , University of Salahaddin/Erbil, to study the effect of five levels of tea residues (0.0, 0.5, 1, 1.5, 2 ton donum-1), four levels (0.0, 50, 100 and 150 Kg donum-1 of P2O5) of phosphorus fertilizer and their combination on phosphorus availability and Chickpea growth. The experiment was a factorial on the basis of completely randomized design with three replications. The results were indicated that the application of tea residues in different levels had a significant effect at (p≤0.01) and (p≤0.05) on available phosphorus in soil, plant phosphorus concentration, total dry matter and relative growth rate, where the highest values (9.83 mg kg-1, 4.57mg g-1, 4.34 gm pot-1 and 0.074 g g-1 plant-1 day-1, respectively) were produced by this treatment (T1). Also, tea residues and phosphorus fertilizer combination, affected significantly (p≤0.01 and p≤0.05) on available phosphorus, plant phosphorus concentration, total dry matter and relative growth rate of chickpea, where the highest values (17.41mg kg-1, 6.57 mg g-1, 8.67 g pot-1 and 0.138 g g-1 plant day-1) were produced from the combination treatment (T1P1) compared to control.
