According to good condition of climate for spinach plantation in Bushehr province during autumn and fall, its extension is sensed to be a demand through the farmers. In order to determine the best method of cultivation (plot, hill and furrow), plant density ( 40x 15, 5Ox 15 60x 15 Cm) and water requirement ( 25, 35, 45 mm cumulative evaporation from class A pan), a study was carried out in Borazjan Agricultural Center druing 2000- 2002. The experiment was done in completely randomized blocks design (split factorial) whith 3 replications. Results showed that the effects of all main factors and their interactions were significant at 1 percent level. The highest yield was obtained from I1B2C1 treatment with average 39.06 ton/ha production. Total consumed water was 5016, 4552 and 4266 m3/ ha/ year for irrigation factors respectively. The best irrigation frequency was showen to be once in each 3 days in the region.
