Influence of different protection systems on the quality of grown soybean seeds

Abstract

Goal. To establish the complex effect of seed pretreatment with treater, biological treatment, postemergence herbicides, fungicide and plant growth regulator on the content of protein and oil in grown soybean seeds, its germinative energy and laboratory germinative. Methods. Methods were field, laboratory, analytical and statistical. The scheme of the experiment to study the integrated use of chemical preparations (treater was Standak Top; postemergence herbicides were Tabezon, Formula, Lemur; fungicide was Acanto Plus 28, plant growth regulator was Vermiiodis, surfactant Trend 90) and biological treatments (Biocomplex-BTU, Phytocide, Liposam) on soya included 15 variants. Determination of protein and oil content in grown soybean seeds was performed using the device “Infralum FT-10”, and the germinative energy and laboratory germinative of seeds – according to DSTU 4138-2002. Results. Soybean seeds grown in weed control variants and on the background of the integrated use of herbicides with other treatments, formed a higher protein content compared to the treatment of its crops only with herbicides. The highest oil content in soybean seeds was formed using Biocomplex-BTU, 1.0 l / t (seed pretreatment) + Tabezon, 2.0 l / ha + Formula, 6 g / ha + Trend 90, 0.2 l / ha (primordial leaves) + Lemur, 1.5 l / ha (2–3 trifoliate leaves) + Phytocide, 0.6 l / ha (bean formation). Protecting soybean crops against weeds with herbicides has helped increase protein and oil collection. The effect of the studied factors on the germination energy of grown soybean seeds was not compared to the absolute control (with weeds, without treatments). All treatment compositions contributed to an increase in laboratory germinative of grown soybean seeds by 4–8%, compared with the absolute control. Conclusions. The results of our research should be taken into account when developing systems to protect soybean crops against pests.
