For determination of the seasonal and monthly water requirement of corn silage, a lysimeter field study was conducted for 3 years (1370-1372 H.S.) in Kabotar-Abad Agricultural Experiment Station, located 30 Km East of Esfahan City in the central plane of Iran. Planting and harvesting seasons were early June and mid-September, respectively. The averaged growing season evapotranspration were 641, 632 and 626 mm and the coresponding Class A pan evaporaton were 628, 625 and 702 mm, respectively. The average growing season from planting- to last- irrigation was 82, days, the averge irrigation water requirment without considering the irrigation for germination enhancement was 633 mm and the class A pan evaporation was 652 mm. The inside lysimeter three year averaged corn silage yield was 93.6 ton/ha, the corn ear yield was 22.7 ton/ha, and number of corn ear were 81000/ha and the plant height was 260 cm.
