The experiment was carried out in Abu Gharaq area, 10 km west of Hilla city, Iraq during the autumn season of 2018 in silt clay soil to study the effect of foam sulfur addition (0 and 20 Kg.ha-1), NPK fertilizer (20:20:20) at levels of 0, 75 and 150 Kg.ha-1, ascorbic acid spraying at concentrations of (0, 25 and 50 mg.L-1) and their interactions on growth of sweet corn. A randomized complete block design with three replications was used. The results showed that the addition of (20 Kg.ha-1) foam sulfur caused a significant increase in plant height (125.9 cm), plant leaf number (12.19), plant leaf area (4206 cm2), chlorophyll (60.4 SPAD), leaf content of N, P and K (15.49, 2.854 and 19.66 mg.g-1) respectively. Increasing the level of NPK up to (150 Kg.ha-1) significantly caused an increase in plant height (126.8 cm), plant leaf number (12.06), plant leaf area (4258 cm2), chlorophyll (61.7 SPAD), leaf content of nitrogen, phosphorus and potassium (15.63, 2.88 and 19.96 mg.g-1) respectively. Spraying ascorbic acid up to (50 mg.L-1) significantly increased plant leaf area (4208), and chlorophyll leaf content (59.2). The interactions between the factors caused a significant effect on most traits.
