Tillage methods under irrigated soils in arid or semiarid regions have not been studied extensively. Four methods: chisel plow and one disking (T 1 ), moldboard plow and two disking (T 2 ), rotary tillage only (T 3 ), and no tillage (T 4 ) were used in the present study. A fullseason corn ( Zea mays L.) hybrid (Israel variety ‘Neveh Vaar 70’) suitable for both silage and grain was planted on a calcareous clay soil at the College of Agriculture Experiment Station in Bajegah, Shiraz. Final plant stand was 50,000/ha. Plant height was used as an indicator of plant growth. Whole plants were harvested during the milk stage and fresh weights were determined. Greatest growth occurred with method T 1 . Silage corn yield were 49.7, 46.1, 44.1, and 40.7 mt/ha for methods T 2 , T 2 , T 3 , and T 4 , respectively.
