This experiment was designed to investigate the effect of seed coating with micronutrient elements, regulators and growth stimulants on the characteristics of germination and seedling establishment of sugar beet seeds, and in the form of a completely randomized design with four repetitions in the year 2020, in the Razavi Seed and Plant Institute was carried out under laboratory and greenhouse conditions. The treatments of this experiment were different combinations of micronutrient elements, regulators and growth stimulants which included 29 treatments along with a control treatment (without coating). The results showed that germination percentage, daily germination rate, germination rate coefficient, root and shoot length, root and shoot dry weight, and seedling root length index were significantly affected. Seed coating treatments were applied. In general, treatment 21, including macro elements + micro elements + humic acid + Gibberellic acid, with a germination percentage of 97%, seedling length index 13.87, allometric coefficient 0.2232, as the best treatment, increasing the mean You have a witness about the treatment. Also, among the different seed coating treatments, treatment 22, including microelements + humic acid + Gibberellic acid + kaolin, had the highest percentage of seedling establishment with 95%. Seed coating with micronutrients, humic acid and Gibberellic acid had the greatest effect on improving seedling growth and quality and germination percentage.

Abstract
This research was carried out to investigate the effect of using seed treatment by Carboxin Thiram, Imidacloprid, polymer, GA3 and Trichoderma (Wild and Mutant with 250gy gamma rays) on Germination Rate, Final Germination Percentage, Seedling length and Vigor index performed at the Seed Technology Laboratory ...

This research was carried out to investigate the effect of using seed treatment by Carboxin Thiram, Imidacloprid, polymer, GA3 and Trichoderma (Wild and Mutant with 250gy gamma rays) on Germination Rate, Final Germination Percentage, Seedling length and Vigor index performed at the Seed Technology Laboratory of Sugar Beet Seed Institute(SBSI). GA3 alone or with chemical treatments and Trichoderma in seed coating increased the germination. Seeds coated with 2g Carboxin Thiram, 2g Imidacloprid , 2g polymerand 1000ppm GA3 showed the highest percentage of germination (99%).The result showed that the use of polymer increased the germination percentage, vigor index and seedling length. Furthermore, application of seed treatment did not show any adverse effects on germination traits. On the other hand, the use of wild species of Trichoderma reduced germination traits. Reduced effect of seed coating by Trichoderma moderated with mutant species, but there was a germination reduction when compared to the control treatment.

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
