The purpose of this study was to investigate the effect of seed coating with combinations of micronutrients, stimulants and growth regulators on emergence, plant establishment and early stages of sugar beet growth in 2018 under greenhouse conditions at Mohaghegh Ardabili University. Experiment was conducted as factorial in a completely randomized design with three replications. Seed washing (washing and not-washing), variety (Shekofa-Persian) and various combinations of micronutrients, stimulants and growth regulators which contains 5 were treated with a control (no cover-up) were the experimental factors. Comparison of the mean data from the experiment showed that among the sugar beet monogerm hybrids, Pars hybrid was superior in terms of establishment percentage. The results of this study showed that seed coating after washing increased the efficiency of sugar beet seed coating treatments. Among different treatments, seed coating treatments 1 [Zn+Mn+B (9, 16.5 and 8.5 g/ kg-1 seed Respectively)+ Gibberellic acid+ Ethylene+ Salicylic acid (1.2, 2 and 0.35 mL/ kg-1 seed, Respectively)] and 2 [Zn+Mn+B (9, 16.5 and 8.5 g/ kg-1 seed Respectively)+ Amino acid+ Humic acid + Seaweed extract (8, 12 and 12 g / kg-1 seed, Respectively)] had the most effect on accelerating emergence and improvement of seedling growth and maximum chlorophyll index and quantum yield of photosystem II were observed in these treatments.
