“…Завдяки високій чутливості кореневої системи зернобобових культур до ураження рослин ґрунтовими патогенами (збудниками кореневих гнилей) зменшується не тільки їх врожайність, а й відбувається значне порушення обміну речовин, і погіршується якість як зерна, так і зеленої маси [13].…”

Аіm. The research was to establish the influence of fertilization systems and methods of main tillage in short-rotation crop rotation on damage to winter wheat and pea plants by root rot. Methods. Field, analytical and statistical. The research was conducted in 2016–2018 at the experimental fields of the Bila Tserkva’s National Agrarian University according to the following scheme: Factor A. Fertilizer systems. 1. Without the use of fertilizers; 2. Organo-mineral; 3. Mineral. Factor B. Systems of basic tillage. 1. Differentiated (control); 2. Police-nonpolice; 3. Shallow shelfless. Short-rotation crop rotations were studied: crop rotation: alfalfa – winter wheat + white mustard, green manure – sugar beets and sunflower – buckwheat – barley with alfalfa subsowing; grain crops: soybean – winter wheat – sunflower – barley – corn for grain; specialized cereal crops: buckwheat – winter wheat – corn for grain, sunflower – barley – sunflower; row crops: peas – winter wheat – sunflower – corn for grain – sunflower. Results. During crop rotation with an organo-mineral fertilization system in the agrocenosis of winter wheat, the development of root rot was 51.3%, which is 8.7% more compared to the option without fertilizers. In the grain-row crop rotation under the organo-mineral fertilization system, root rot damage was 50%, which is 6.1% less compared to the unfertilized plot. Under the inter-row specialized crop rotation, the damage to winter wheat plants and the development of diseases amounted to 55.4%, which increased by 10.5% compared to the inter-row crop rotation. Affected pea plants by root rot in the flowering phase under shelf-less tillage, the development of the disease was 4.7% higher compared to differentiated tillage. Conclusions. The article presents the results of field studies on the application of fertilization systems and methods of basic tillage to the damage of winter wheat and pea plants by root rot in short-rotational crop rotations in the conditions of the Forest Steppe of Ukraine. The greatest damage to winter wheat plants by root rot was recorded during the row rotation, the predecessor of which was peas. On average, 32.6–37.6% of wheat plants were affected by the disease in these areas, and the intensity of the disease was 52.4–58.7%. The lowest development of root rots of winter wheat plants (27.4–35.4%) was found in the grain row specialized crop rotation. The smallest development of root rots of winter wheat plants was found under the organo-mineral fertilization system. Shallow cultivation with disc tools to a depth of 10–12 cm caused the highest development of pea root rot. Plowing under peas helped reduce the spread and development of pea root rot.

“…Dubey et al (2020) show the role of biostimulants in the mechanisms of protection of Fabaceae plants from abiotic stresses, stimulation of growth processes, nutrient recycling, improvement of grain quality, and increase of crop yields. A lot of evidence has been accumulated that demonstrates the positive results of using growth regulators in soybean (Shepilova et al, 2021), pea (Nebaba, 2023), bean (Pyda et al, 2021), and cereal grains (Lemishko et al, 2022), which contribute to a significant increase in the activity of symbiotic and associative nitrogen fixation and increase yields. N. Khan et al (2020) showed that chickpea plants treated with growth regulators (salicylic acid, putrescine) had a higher height and weight of the aerial parts of plants, increased chlorophyll, protein, and sugar content, and increased yield.…”

The article summarizes the results of research on the structure of weed agrocenosis of vegetable peas; controlling the level of its weeding by performing pre-emergence and post-emergence harrowing with medium toothed harrows; evaluation of the chemical method of protection of vegetable peas from weeds, which involved the introduction of 2 types of herbicides, which contained such active substances as S-metallochlor and Imazamox. Part of the study areas was treated with the microfertilizer Reacoma-chelate of boron + molybdenum with a rate of 1.0 l / ha before flowering peas. As a result of research, it was found that in the structure of weed agrocenosis of vegetable peas the share of monocotyledonous weeds averaged 71.4% in two years of research and, accordingly, dicotyledonous - 28.6%. But the air-dry mass of cereal weeds was much lower than that of deciduous weeds. The implementation of agronomic measures alone did not allow to keep the presence of weeds in crops below the level of economic damage throughout the growing season. Prior to harvesting, this variant accounted for 18 weeds / m2 of weed stalks. This agricultural measure reduced the level of their presence by 69.5% and 45.8% of air-dry weight compared to the control option. The application of a soil herbicide based on S-metallochlorine provided a reduction in the number of weeds in the month after spraying by 85.7% compared to the control version. Before harvesting vegetable peas, the number of weeds in the areas where the soil herbicide was applied was 11 pieces / m2, and the level of weeding decreased by 81.4% compared to the control variant. At the time of the second weed count, we found that the herbicide with the active ingredient Imazamox was 89.8% effective. Consecutive application of S-metallochlor and Imazamox with reduced consumption rates allowed to control the presence of weeds in agrophytocenoses throughout the growing season of vegetable peas. Weed mortality at the time of harvest in this variant averaged 89.8% over two years of research, and their above-ground air-dry mass was 95 g / m2. On average, in two years of our research, the yield of peas in the variants with the application of herbicides was 5.00-5,64 t / ha, which was 35.5-52.8% higher than in the control areas. The highest increase in pea yield was obtained with the successive application of S-metallochlor and Imazamox with reduced consumption rates. On the average for two years of researches it made 1.95 t / hectare. Before flowering of vegetables, the application of micro-fertilizer Reacom-chelate of boron + molybdenum with a consumption rate of 1.0 l / ha made it possible to obtain higher yields of 3.7-6.1% compared to uncultivated areas on agronomic and chemical weed protection options.
