This experiment was conducted to determine the most suitable planting date of cucumber under semitunnel and polyethylene mulches conditions in kaboutarabad reseach station of Isfahan during 2003 and 2004.The experimental design was a radomized complete block in a split plot arrangment with four replications. Four planting dates(Febrary 4th, Febrary 19th, March 6th and March 21)formed the main plots and soil covers (semi tunnel with black and transparent polyethylene mulches and semi tunnel without mulch)formed the subplots. The anova of date showed: planting dates had no significant effect on yield but was effective in early maturing yield. Planting date of febrary 19th produced the higest yield (6.4 T/ha).Soil cover had significant effect on considering traits. The highest yield ,plant vegetative growth and early maturing fruits obtaind in semi tunnel with transparent mulch. Applying semi tunnel with transparent and black mulches during Febrary 19th till March 6th had the best efficiency for producing out of season cucumber in Isfahan climatic conditions. Polyethylene mulches reduced the salt accumulation on farrows.
