The experiment was carried out in Abu Gharq (10 km west of the Hillah city) during the fall season 2019, in silt clay loam soil, to study the effect of three planting dates (15 July, 1 August and 15 August), two plant densities (40000 and 80,000 plantha1), and silicon spraying with four concentrations (0,1.5,3.0, and 4.5 ml/ L1) and their interaction on yield of sweet corn hybrid. Split-split arrangement according to randomized complete block design (RCBD) with three replications was used. The datawere analyzed and the averages were tested according to the least significant difference at 0.05 probability level. The most important results obtained that, seeding dates affected most of the outcome indicators , and 15 August achieved the highest number of rows (18.52) per year, grains per row ( 316.3 grains), weight of 100 grains (32.52 g), plant grain yield (130.2 g) and total grain yield ( 8.011 t ha"1). The plant density caused significant effect, and the low density achieved the highest ear rowsnumber (15.42) and plant grain yield, while high density achieved the highest total grain yield (7.1021 ha1). Silicon spraying caused significant effect and the concentration of 4.5 ml/L"1 gave high plant grain yield (94.4 g). The interactions had a significant effect on most of the studied traits.
