“…The noticeable development of root rot is determined by the high saturation of crop rotations with susceptible crops and monocultures, provoking the accumulation of pathogens, and low suppressiveness of soils, contributing to the long-term survival and preservation of dormant structures [4,5].…”

The widespread production of grain crops and the rejection of the classical technology of tillage led to a noticeable increase in the prevalence and harmfulness of phytopathogens. First of all, this applies to facultative parasites with a wide specialization - Bipolaris, Fusarium, as well as secondary fungi from the genus Alternaria, Cladosporium, Penicillium, etc. At the same time, there is a change of dominance among these species. The predominant niche is occupied by fungi of the genus Fusarium, instead of species of the genus Bipolaris. The infestation of not only the seed material with this pathogen, but also the root system requires the selection of approaches to reduce this pathogen development. The use of modern fungicides with chemical or biological substances in their composition can protect plants from the pathogen and affect yield.

Under the conditions of the Trans-Urals the cultivation of varieties of field pea allows us to get high yields, not inferior to grain, provides high profitability and solves the problem of protein in animal husbandry. Its inclusion in the crop rotation contributes to the improvement of soil fertility, yield and product quality of subsequent crops. Pea seeds depending on the variety and cultivation conditions contain (in % per dry matter): 9–15 water, 18–35 protein, 46–60 nitrogen-free extractives (including 20–50 % starch, 4–10 % sugars), 0,6–1,5 fat, 2–10 fiber, 2–4 ash. The purpose of the research was to determine the economic and biological value of varieties of field pea and the influence of biotic and abiotic factors on crop yield under the conditions of the Trans-Urals. According to the results of three years of study a good level of yield was noted in the varieties recommended for cultivation in the Ural region, which includes the Kurgan region: Aksaysky Usaty 55–2,47 t/ha; Agrointel – 1,88 t/ha, Zauralsky 3–2,12 t/ha, Samarius – 2,40 t/ha. Among the new varieties the high yield was shown by the varieties Kulon – 2,75 t/ha, Yamal 305–1,94 t/ha, Chevron – 1,84 t/ha. The increase in the seed yield of pea varieties with the use of urea (N₃₀) was noted for all the studied varieties. So, for example, for Sibur 2 variety by 1,11 times, for Aksaysky Usaty 55 and Samat varieties by 1,12, for Samarius variety by 1,15 times. The use of urea and double superphosphate (N₃₀P₃₀) to obtain the maximum yield for the studied varieties of peas allowed to increase the yield for the variety Aksaysky Usaty 55 by 1,18 times, Samat and Sibur 2 by 1,17, Samarius by 1,2 times.

Климатические условия Зауралья весьма своеобразны и сложны, часто неблагоприятны для сельскохозяйственных культур. В засушливые годы у гороха сокращается вегетационный период, и он лучше других культур использует запасы влаги в почве. В засушливых условиях репродуцирования стандартный сорт Аксайский усатый 55 сформировал урожайность в среднем за три года 1,56 т/га. Превысили по урожайности стандарт сорта Агроинтел – 1,69 т/га, Зауральский 3 – 1,70 т/га, Самариус – 1,79 т/га, Сибур 2 – 1,82 т/га. Применение современных фунгицидов для борьбы с листо-стеблевыми болезнями в фитосанитарной технологии возделывания гороха посевного позволило сохранить урожай семян. Прибавка урожая отмечена по всем сортам во всех вариантах опыта. Так, в среднем за годы испытания сохраненный урожай по сортам в варианте с Винтаж, МЭ – 1 л/га составил 0,25 т/га, препарата Титул Дуо, ККР – 0,4 л/га – 0,19 т/га, по Колосаль Про, КМЭ – 0,3 л/га – 0,25 т/га. Все изученные регуляторы роста в засушливых условиях репродуцирования способствовали увеличению урожайности семян сортов гороха посевного. Так, если в контроле по сорту Аксайский усатый 55 урожайность составила 1,56 т/га, то регуляторы роста способствовали росту урожайности с 1,70 т/га в варианте Иммуноцитофит 1 таб./т + 1 таб./га до 1,80 т/га в вариантах с Альбит 50 мл/т + 30 мл/га и Эпин 200 мл/т + 50 мл/га.
