Abstract: The experiment was carried out in private field in Abu Gharaq (10 km west of Hilla city) during the fall season 2019, to study the effect of planting dates (July 15, August 1 and 15) and plant density (40 and 80 thousand plants ha-1, silicon spraying levels (0, 1.5, 3.0, and 4.5 ml l-1) and their interactions on the growth and yield of sweet corn. Split-split-plot arrangement following a randomized complete block design (R.C.B.D) with three replications was used. The results were analyzed and the averages were tested according to the least significant difference at the 0.05 probability level. The most important results are summarized as follows: Planting on July 15 delayed the day's number to 50% silkinging to 53.21 days compared to August 1 (51.71 days), and decreased ripening single ear weight with sheaths to 104.3 g compared to August 15 which achieved 244,9 g. High plant density caused significant increase in 50% silking, and leaf area index to 53.75 days and 2.998, without significant effect on ripening single ear weight with sheaths. Silicon spraying levels caused significant effect on ear ripening weight, and 3 ml l-1 achieved high weight 174.8 g compared to 169.4 g from control treatment.
