The present investigation entitled Effect of Irrigation Water Quality and Foliar Application of Ascorbic Acid and osmosterase on Maize yield (Zea mays L.).The experiment was carried out in spring season 2021 at the field of Ibn Al - Bitar Vocational Preparatory ,Iraq , Karbala . The experiment was laid out in split plot based on Randomized complete block design (RCBD) with three replications .The experiment consisted of Irrigation Water Quality @ ( A1,A2 and A3 ) and Foliar Application of Ascorbic Acid ( 500 and 750 ) mg.L-1 and osmosterase (300 and 600 ) ml.L-1 . The maximum of Grain yield , total yield and biological yield which was recorded ( 184.0) gm plant-1 , (9.745 and 4.200 ) tons. ha-1 respectively were recorded in irrigation with river water with 750 mg.L-1 of ascorbic spraying ,while The maximum of 500 grain weight and dry weight which was recorded ( 139.00 g and 2.050 kg.plant -1 ) respectively were recorded in irrigation with water river with 600 ml.L-1 of osmosterase
