A significant degree of ploughness of agricultural lands of Ukraine has led to increased erosion and the creation of soils of varying degrees of washout, which leads to dehumification and contamination of soils with toxic substances. Therefore, the purpose of the study was to establish the features of horizontal migration and accumulation of heavy metals of lead, cadmium, copper, and zinc, trace elements of boron and manganese, radionuclides of caesium and strontium on podzolic heavy loamy chernozems with varying degrees of washout: non-eroded, weak and medium washout, conditioned by the development of erosion processes. During the study, spectrophotometric, colorimetric, gamma-spectrometric, and radiochemical methods were used to determine the content of toxic substances in the soil. The study results showed that on slightly washed soils, the content of humus is 12.9% less, easily hydrolysed nitrogen – 13.3%, mobile forms of phosphorus – 51.1%, mobile potassium – 34.9% less than on slightly washed soils. The humus content on medium-washed soil was 8.8% less than on lightly washed soil, easily hydrolysed nitrogen – 14.3% less, mobile phosphorus – 15.3% more, mobile potassium – 42.9% more. A strong horizontal migration of mobile lead forms in washed podzolic heavy loamy chernozem was established, which increases with increasing degree of soil washout with the content of mobile lead forms on medium-washed soil by 24% more than on non-eroded soil. The same dependence was established on the content of mobile forms of zinc in the soil, with their predominance on medium-washed soil by 17 %, compared to non-washed. The content of mobile forms of copper is lower on slightly washed soil, compared to non – washed soil by 5%, boron – 18.8% less on non-washed soil, compared to medium-washed, and the content of mobile forms of manganese increases by 3.3% from slightly to medium-washed soil. It was also found that the concentration of caesium decreased by 25.6% on medium-washed soils, compared to non-washed ones

The article presents the results of research of growth processes and anatomical indicators of wheat culture of the variety Kraevid, depending on the treatment with the growth-regulating preparation – tebuconazole (0,5% and 1%). The tebuconazole was treated by spraying the aerial part and introduction through the root system. It has been established that the use of tebuconazole of different physiological-active concentrations (1% and 0.5%) in different methods of introducing into the plant (through the root and through spraying) led to a slowing of linear growth and inhibition of the root growth of wheat plants. The most distinct effect was observed with the use of 1% tebuconazole when the retardant was treated through the root. Treatment of wheat plants with tebuconazole through root and spraying caused significant changes in water metabolism and photosynthesis of plants: the linear size of stomata decreased, that led to reduction of the stomata area. It was found that when the tebuconazole was fed through the root, the transpiration intensity was higher than in the variant with the spraying of plants.

On poorly washed chernozems podzolized with hard loam, the humus content decreases by 12.9%, compared with unwashed soils. Low-washed chernozems podzolic had a content of easily hydrolyzed nitrogen by 13.3% less than unwashed. The content of mobile forms of phosphorus on slightly washed soils decreased by 51.1%. The content of mobile potassium on unwashed chernozem podzolic heavy loam was 34.9% higher than on weakly washed soil. Observations of chernozem podzolic heavy loam medium washed showed that the humus content decreased by 8.8% compared to slightly washed. The content of easily hydrolyzed nitrogen decreased by 14.3%. The content of mobile forms of phosphorus increased by 15.3%. The content of mobile forms of potassium increased by 42.9%. Hydrolytic acidity of slightly washed soil increased by 4.9%. The reaction of the soil solution - by 1.8%. The amount of absorbed bases increased by 11.4%. Medium-washed chernozem podzolic heavy loam had hydrolytic acidity 11.3% higher than slightly washed. The reaction of the soil solution was 1.7% lower. The amount of absorbed bases was the same. Changes in the agrochemical composition of podzolic heavy loam chernozem on unwashed and lightly washed soils showed that weak soil erosion leads to a decrease in humus, easily hydrolyzed nitrogen, mobile forms of phosphorus and potassium, increasing the value of hydrolytic acidity, and the amount of solute. The largest decrease in the content of mobile forms of phosphorus - by 51.1% and the smallest and almost identical decrease in the content of humus and easily hydrolyzed nitrogen - by 12.9-13.3%. The sum of absorbed bases increased the most among the indicators of acidity of chernozem podzolized heavy-washed slightly washed, in comparison with the unwashed one, by 11.4%, and the reaction of soil pH solution increased the least - by 1.8%. From the agroecological point of view, weak soil erosion causes deterioration of such soil fertility indicators as reduction of humus content, easily hydrolyzed nitrogen, mobile forms of phosphorus and potassium, increase of soil hydrolytic acidity. At the same time, the reaction rates of the soil salt solution in the neutral direction improve and the amount of absorbed bases increases. A similar dependence is observed when comparing the agrochemical parameters of weakly and medium-washed chernozem podzolic hard loam. In particular, a decrease in the content of humus, easily hydrolyzed nitrogen, a decrease in the magnitude of the reaction of the soil pH solution and an increase in hydrolytic acidity, which are negative factors. The largest negative manifestation was observed on the decrease in the value of hydrolytic acidity of the medium-washed soil - by 14.3%, and the least - on the value of the reaction of the soil pH solution - by 1.7%. At the same time, the increase in the degree of soil erosion from slightly washed to medium washed led to an increase in the medium washed chernozem podzolic heavy loam content of mobile forms of phosphorus and especially potassium, the content of which increased by 42.9%. Comparison of the change in the agrochemical condition of chernozem podzolic heavy loam slightly washed with medium washed showed that the humus content decreases more intensively in slightly washed soil, compared with the average washed, by 4.1%; the content of easily hydrolyzed nitrogen decreased more intensively in medium-washed soil, compared with slightly washed, by 1%. Hydrolytic acidity has increased by 6.4% more intensively on moderately washed soils compared to poorly washed soils.

The lack of information on the cultivation of varieties of peas, as fodder crops, for seeds, leads to low yields of its seeds with significant losses. Purpose of research. Therefore, the aim of our research was to analyze according to the State Register of Plant varieties suitable for growing in Ukraine in 2022. indicators of seed productivity, environmental sustainability and technological suitability for mechanized harvesting of winter and spring pea varieties. Research methods. The quality indicators of winter pea varieties (Vicia villosa Roth.) And spring (Vicia sativa L. spring) were analyzed according to a set of indicators: drought resistance (scores), disease resistance (scores), pest resistance (scores), resistance to lodging (points), winter hardiness (points), resistance to seed shedding (points), seed yield (c / ha). The score was performed according to the following gradation: 9 points - the highest stability; 1 point - the lowest stability. Resistance of pea plants to such diseases as ascochitosis, rust was evaluated and pest - pea seed. Research results. As of 2022, the State Register of Plant Varieties of Ukraine includes three varieties of winter sowing peas and 25 varieties of spring sowing peas. Among the winter pea varieties included in the State Register of Plant Varieties Suitable for Distribution in Ukraine in 2022, the highest seed yield and winter hardiness is Swan Song - 20.2 c / ha, the most drought-resistant are Swan Song and Pearl, the most resistant to disease are Neoplant variety, and before the lodging of plants - Pearl. Among the spring pea varieties, the most productive in terms of seed yield are Volodymyr - 24.5 c / ha, Ariadna, Nakhodka - 23.0 c / ha, New Belgrade - 22.0 c / ha and Bila Tserkva 10-22.8 c / ha. The most resistant to diseases are varieties Ozyryana, Pivdennobuzka, Dionis, Natalka, Ltava, Podilska rannya, Vesnyanka, Winner; before the drought - Nadiya Podillya, Podilska Rannya, Ltava, Vesnyanka, Natalka; before lying down - Ariadna, Natalka and Oziryana; before the seeds fall off - New Belgrade, Find, Ariadne, Ltava, Vesnyanka, Podilska early. Conclusions. Comparison of indicators of agroecological stability and seed productivity of winter and spring forms of sowing peas showed that in terms of drought resistance winter and spring varieties do not differ in average; in terms of resistance to diseases, spring pea varieties are 0.1 points more resistant than winter forms; resistance to lodging of the stem was 0.7 points higher in winter pea varieties than in spring forms; seed yield was 21.5% higher in spring forms, compared with winter, probably, winter peas provide higher yields of vegetative fodder base.
