Plant protectors effect on the soybean Sfera varieties yield in the Primorsky region

Field studies were carried out on the experimental fields of the seed production laboratory of the Federal State Budgetary Scientific Institution "Federal Scientific Center for Agrobiotechnology of the Far East named after A.K. Chaika". The purpose of research is to establish the effect of new generation means of protection and biological products on increasing the resistance of soybean plants to unfavorable environmental factors, improving their economically valuable traits in the conditions of the Primorsky Region. Research objectives: to study the effect of plant protection products, foliar dressing, dressing agents on the yielding and sowing qualities of seeds, the defeat of fungal diseases. The object of research is the mid-season soybean variety Sfera. Soybean cultivation technology is generally accepted in the Primorsky Region. Seed disinfectants were studied: Maxim ΧL, Orgamika S, Imidor PRO and foliar dressing Polygro Bits, Biodux. The maximum yield on average for two years of research and the yield of the seed fraction were obtained in the variant with the use of the biofungicidal dressing agent Orgamik C and the insecticidal dressing agent Imidor PRO KS, the introduction of foliar feeding of Polygro Bits during the growing season of plants. Seed germination in all variants corresponded to the requirements of GOST R52325-2005. The indicators of seed productivity in the variants with the use of means of protection and foliar dressing were higher than in the variant without seed treatment and top dressing (up to 4.9 g/plant). The use of dressing agents and dressings did not have a significant effect on the content of oil and protein in soybean seeds, which amounted to 22.7-23.2 and 38.3-39.5 %, respectively.
