Abstract. The study was aimed to determine and compare some technological properties of different wheat species samples (Triticum spelta L.; Triticum dicoccum (Schrank) Schuebl. and coloured-grain wheat (Triticum aestivum L.)) originated from Central Ukraine location. Those species were evaluated and compared in traits related to ethanol production as the grain yield, content of protein, starch, and falling number. The research was based on the field experiment carried out at the Agronomy experimental station of the National University of Life and Environmental Sciences of Ukraine (Kyiv region) during the period 2014-2015. The data were analysed using ANOVA method. The difference of the weather conditions among the experimental years did not have significant influence on the examined parameters. On the other hand, quality parameters significantly depended on the wheat species. The results obtained indicated significant difference between species in the ethanol yield and falling number compared to protein and starch content. The highest ethanol yield was detected in colouredgrain wheat 8.72-8.80 w/w % due to the highest starch content 64.4 % in average. At the same time the ability of foaming, which causes negative effect during the fermentation process, was the highest in emmer wheat samples 20.8 ml⋅g -1 . Overall it should be noted that all three examined wheat species had poor technological properties for bread producing in most characteristics; that is why it is necessary to look for other ways of processing these grain.

Lead (Pb) is a widespread pollutant presented in soil, by various compounds. However, only mobile forms represent a danger to living organisms. The mobile compounds are those extracted with 0.1 and 1.0 HCl. Soil indexes likethe content of particles less than 0.001 mm (clay), soil organic matter (SOM) content, pH status of the soil solution significantly affect the mobility of lead. Application of mineral and organic fertilizers can enhance or reduce the mobility of lead in soil as well. The influence of fertilizers on the mobility of lead, as well as the peculiarities of its translocation into plants, was investigated at long-term-field experiments in three main climatic zones of Ukraine (Polissya, Forest-steppe, Steppe). We found that the soil parameters had the influence on lead mobility were in the following sequence: clay content> SOM > soil рН. There was a strong inverse correlation between lead mobility and soil parameters (r = 0.821-0.962). Application of mineral fertilizers increased the content of lead mobile forms in soil (by 7-24%), whereas organic fertilizers contributed to its decrease. Crops were ranged by the ability for lead accumulation in the following order: clover> sugar beets > corn> sunflower> winter wheat. Furthermore, mineral fertilizers contributed significantly to lead translocation from the soil to crops, while the influence of organic fertilizers on this process was insignificant.

Intensification of agricultural production provides the development and introduction of new, progressive, and cost-effective practices, including plant growth regulators. The effect of various growth regulators on the productivity of fodder beet of the Eckendorf yellow variety type was studied in the conditions of the Central-Non-Chernozem region of the Russian Federation in an experimental field in the Kaluga branch of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy in the period from 2019 to 2021. The studies found that the level of productivity of fodder beet under the action of various growth regulators relative to the control variant significantly increases during pre-sowing seed treatment on 5–10,9% and when using phytoregulators by vegetation on 4,8–11,5%. The most significant increase in productivity and the yield of absolutely dry substances of root crops were noted in an intensive version of the technology using growth regulators Biodux and Zircon. The yield range for three years with these regulators was in the range of 560–561 c/ha, the yield of ACB was 72,5–72,8 c/ha during seed etching, and 559–564 c/ha and the yield of ACB72,5–73,1 c/ha during foliar treatments. In general, the percentage increase in the content of absolutely dry matter of fodder beetroots relative to the control variant with the use of growth regulators was 0,24–0,25%, the increase in the yield of feed units for variants with pre-sowing use of growth regulators was 3–6,6 c/ha or 4,9–10,9%, with foliar application – 2,8–7 c/ha or 4,6–11,5%. Thus, the research work for 2019–2021 proved the effectiveness of modern growth regulators in the Non-Chernozem zone of the Russian Federation.
