Abstract
Due to good climatic condition for producing spinach during autumn in Bushehr province, a study was carried out in Borazjan Agricultural Center during 2001–2002 to determine the effects of irrigation regimes, plant density and cultivation method on spinach. The experiment was based on a complete randomized block design having split factorials with three replications with the following treatments: three methods of cultivation (plant rows in basin (B1), ordinary bed and furrow (B2), and on upper part of furrow (B3) ); three plant densities (40×15 (C1), 50×15 (C2), and 60×15 (C3) centimeters); and three irrigation intervals (I1=25mm, I2=35mm, and I3=45mm based on cumulative evaporation from a class A pan). Results showed that the effects of all main factors and their interactions were significant at P
