Abstract: An important direction of agricultural production and improvement of the technology of increasing the yield of leguminous crops, in particular winter peas, is the use of modern plant growth regulators and bacterial drugs, their complex application and the implementation of foliar fertilizing with microfertilizers.The purpose of the research was to study the effect of pre-sowing seed treatment with plant growth regulator Endophyt-L1 РК, the bacterial drug BTU-p, their complex application and two foliar fertilizers (at the phase of 3-5 leaves of LF-LEGUMES and at the phase of 3-5 of LF-LEGUMES and during budding phase LF-BEAN + Biobor 140) on the height and biomass growth of winter pea plants of NC Moroz and Enduro varieties.Field research was carried out during 2019-2022 on the basis of the trail farm 'Agronomichne' of Vinnytsia National Agrarian University at Agronomichne village, Vinnytsia district, Vinnytsia region.The research program provided for the establishment of a three-factor field experiment in which the varieties were studied (factor A), pre-sowing treatment of seeds of PPP Endophyt-L1 PK, BTU-p inoculants, their complex application (factor B) and foliar fertilizing (factor C) at the 3-5 leaves phase with microfertilizers LF-LEGUMES and at the phase of 3-5 of LF-LEGUMES and budding LF-BEAN + Biobor 140.Winter pea NC Moroz and Enduro varieties were studied.The positive effect on the increase of plant height of winter pea NC Moroz and Enduro varieties was established for applying mineral fertilizers at N 45 Р 45 К 45 doses and foliar fertilizing at various rates and phases with microfertilizers LF-LEGUMES and Biobor 140.At the phase of bean formation, over three years of research the average value of plant height was 71-75 cm and 70-74 cm, in winter peas of NC Moroz and Enduro varieties, respectively, which corresponded to their varietal characteristics.Pre-sowing treatment complex Endophyt L1 PK + BTU-p amid main fertilizer N 45 P 45 K 45 and with two foliar top-dressings with microfertilizers at different phases of development ensured an increase in the height of plant of varieties NC Moroz and Enduro by 5-10% and 6-9%, respectively, in comparison to the control.It was investigated that the greatest biomass of winter pea plants of NC Moroz and Enduro varieties was noted in the variants of the complex application of pre-sowing treatment Endophyte L1 PK and BTU-p with N 45 P 45 K 45 fertilizer and two-fold fertilizing (3-5 leaves and budding phases) LF-LEAN and LF -LEGUMESES + Biobor 140.At the budding, flowering, and bean formation, the weight of plants increased by 66%, 24%, 15% and 67%, 29%, and 15%, respectively, compared to the control without pre-sowing treatment.Single-dose fertilizer applying at the phase of 3-5 leaves, the indicators increased by 45%, 14%, 12% and 46%, 17%, and 12%, respectively, according to the above-mentioned phases and varieties Key words: plant growth regulators, bacterial preparations, growth, biomass, fertilizing, winter peas.

Вплив передпосівної обробки насіння та позакореневих підживлень на ростові процеси сортів гороху озимогоВажливим напрямком сільськогосподарського виробництва та удосконалення технології підвищення врожайності зернобобових культур, зокрема гороху озимого, є застосування сучасних вітчизняних регуляторів росту рослин і бактеріального препаратів, їх комплексного застосування та здійснення позакореневих підживлень мікродобривами.Метою проведення досліджень було вивчення дії передпосівної обробки насіння регулятором росту рослин Ендофіт-L1 РК, бактеріальним препаратом БТУ-р, їх комплексного застосування та двох позакореневих підживлень (у фазу 3-5-ти листків LF-БОБОВІ та у фази 3-5-ти лисків LF-БОБОВІ і у бутонізації LF-БОБОВІ + Біобор 140) на висоту та наростання біомаси рослин гороху озимого сортів НС Мороз та Ендуро.Польові дослідження виконували впродовж 2019-2022 років на базі дослідного господарства
