The experiment was conducted to test various irrigation patterns for maximum yield at Sindh Agriculture University, Tando Jam, during the year 1999. All the cultural practices were adopted to maintain the area free from weeds and insect pests. The results of the experiment showed the superiority of irrigation pattern where canal water (ECe 0.5 to 1.00 dS/cm) was applied followed by those irrigation patterns where canal irrigation water was used in two growth stages which recorded highest values of plant stand, plant height, cob length, cob diameter, cob number, seed index, dry forage and grain yield. The lowest growth and yield contributing parameter values were exhibited in those irrigation patterns where pumped saline water (ECe 1.25 to 1.50 dS/cm was used during the growing period or pumped saline water was applied in two growing stages of the corn crop. Based on the results it is recommended that canal water should be used during the growing period. But, if there is scarcity of canal water then pumped saline water could be used in one growth stage and canal water in other growth stages. Kev words: Corn. vield. irriaation. water Qualities
