A field experiment was conducted in the spring season of 2021 M at Ibn Al-Bitar Professional High School located in the Al- Otaishi area of Al-Hussainiya district of the Holy Karbala governorate in Iraq to study the effect of irrigation water quality and foliar feeding spraying with ascorbic acid and oosmostras in some phenotypic traits of the corn starch Zea mays L . The design of the randomized complete sectors (RCBD ) and the arrangement of the split panels was chosen as a factorial experiment with two factors, as the first factor included the quality of irrigation water in three levels ( A1 ). and A2 and A3 while the second factor was foliar spraying on the foliage of maize plants with two concentrations of ascorbic acid ( 500 mg L -1 and 750 mg L -1 ) , as well as spraying with two (concentrations of osmosteras 300 ml L -1 and 600 ml . L -1 ) in addition to the comparison treatment, which is spraying with distilled water for one time only. And by three replications. Resultsof the interaction between factors A indicated water quality and C foliar feeding (spraying with ascorbic and Osmostras ) , the results showed the superiority of the treatment Airrigation with river water and (spraying ascorbic 750 mg.L -1 ) in the following studied traits ( corn cob length 21,677 cm and corncob diameter 4.267 cm and the total number of grains in corn cob 676.7) grains.
