< p >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. This study was carried out in greenhouse conditions at Mohaghegh Ardabili University in 2018. Experiment was conducted as factorial in a completely randomized design with three replications. Seed washing (washing and not-washing), varity (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.

This study aimed to evaluate the effect of sugar beet (Beta vulgaris) seed coating with micronutrients on the germination, plant establishment and seedling growth characteristics was conducted as factorial in a completely randomized design with three replications in 2015 at the sugar beet seed Institute under laboratory and greenhouse conditions. Hybrids (Shkofa-Pars) and seed coating with various combinations of micronutrients, which contains 14 treatments and a control (no cover-up) were the experimental factors. The results showed that percentage, rate, emergency and seedling growth characteristics significantly affected by the hybrid and also the treatment of the Seed coating. The results showed that the hybrid of PARS in terms of germination and emergence and early seedling growth was better than hybrid of SHKOFA. Germination percentage in control was equivalent to 91.16 percent and percentage of germination except for treatment coated with boron, was greater than control, was greater. Seed coating treatment with Zn+ Mn+ B (0.456 Zn +1.502 Mn + 2.189 B g kg-1 seed) with 97% germination had the highest percentage of germination. Among the different treatments of seed coating, seed treatments with Zn 0.912 and 1.367 g per kg of seed and seed treatment with Mn 4.507 per kg of seed than other treatments had the highest amount of root dry weight. Root dry weight in the seed coating with B 4.379 and 6.568 g per kg of seed, compared to control treatments was reduced by 11.15 and 18.76 percent respectively
