Abstract: 

This experimental was done as split plot in the basis of completely randomized blocks design with tree replication in Mazandaran province in 2009. Main factor was sowing date (August 16, 24, 31 and 7 September) and sub factor was row spacing (65, 75 and 85 cm). The results showed that the maximum plant height and plant dry weight were obtained on August 16 and most of the ear diameter, grain number per row, grain number per ear, grain weight, green ear yield and harvest index were conducted on August 24. Most of the plant height, ear length and plant dry weight were gained at rows space 65 cm and the maximum grain number per row, grain weight, green ear yield and harvest index were obtained at row space of 75 cm. Maximum of the plant height and plant dry weight were obtained on interaction effect of the 16 August and rows space 65 cm. The most amounts of green ear yield and grain yield were obtained in the August 24 and rows space 75 cm. Sowing date 24 August introduced the best treatment, because in this sowing date increased ear diameter, grain number per row, grain number per ear, grain weight, green ear yield and harvest index that introduce as the most important traits of sweet corn. The Rows space 75 cm determined as the best because in this treatment grain weight, green ear yield and harvest index increased.
