Abstract Abstract. In the technological process, the applying of retardants is a perspective way of increasing the yield of different crops. The purpose of our work was to study the influence of different inhibitory type drugs on the morphogenesis of seedlings and the sowing characteristics of fodder bean seeds. The research was conducted on the culture of fodder beans of Vizir variety. Pre-sowing treatment of seeds with aqueous solutions of esfon (0,2%), chlormequat chloride (0,5%) and tebuconazole (0,5%) was carried out, and control seeds were treated with water. In the process of research, the germination energy and the general germination of the seeds, the length of the hypocotyl and the main root of the seedlings, the diameter of the root cervix were established. It was found that pre-sowing tratment of seeds with retardants esfon (0,2%), chlormequat chloride (0,5%) and tebuconazole (0,5%) leads to significant changes in morphogenesis of seedlings of fodder bean culture. The drugs inhibit the growth of the hypocotyl and reduce the length of the main root. The greatest growth suppress effect was found with the use of the triazole derivative retardant tebuconazole (0,5%). It was established that retardants increased germination energy, but had a little effect on general seed germination. The greatest effect of increasing seed germination energy was observed with the use of tebuconazole (0,5%). The question of investigation of the impact of new generation retardants on the productivity of different varieties of legumes remains relevant.
