In the results conducted between studies, the studied regulators affect the biometrics and yield of table carrot plants. The greatest influence on the interphase period "root formation - technical maturity" was performed by the regulator Phytocid-r, which helped reduce the growth of the interphase period Shantane KL by 3 days, in the hybrid Brilliance F1 by 4 days. With the use of the growth regulator Phytocid-r of the vegetation period of the population in the variety Shantane KL – 117 days, in the hybrid Brilliance F1 – 118 days, respectively 6 and 7 days shorter with control. The highest weight of root crops during the growing season was observed using the growth regulator Phytocid-p, in the variety Shantane KL the increase relative to control was 15.5 – 23.7 g, in the hybrid Brilliance F1 – 18.5 and 25.5 g. root crops were also characterized by variants using growth regulators Ivin and Emistym C, where the increase relative to the control at the end of the growing season was: in the variety Shantane KL – 4.1-8.3 g, in the hybrid Brilliance F1 – 4.9 and 6.0 g respectively. The growing season of table carrots was characterized by slightly higher temperatures and low rainfall, with a long dry period, which negatively affected the formation of roots of table carrots. However, the highest yield was obtained from the option using the growth regulator Phytocid-p, which provided an increase in yield at the level: in the variety Shantane KL – 8.5 t / ha, in the hybrid Brilliance F1 – 13.3 t / ha. The highest percentage of marketable yield was obtained using the growth regulator Phytocid-p in both varieties and hybrids – 94.8 and 95.2 %, which is more than the control by 11.2 and 11.0 %. The largest mass of root crop was formed by plants using the growth regulator Phytocid-r: in the variety Shantane KL – 112 g, in the hybrid Brilliance F1 – 118 g, which is 23.8 and 25.6 g more than the control. The diameter of the root was in the range of 5.8-7.0 cm and varied slightly from the growth regulator. The hybrid Brilliance F1 was characterized by a longer root length. However, taking into account the applied growth regulator, it was found that the highest figure was for the use of Phytocid-r: in the variety Shantane KL – 17.6 cm, in the hybrid Brilliance F1 – 18.3 cm, which is more than the option without treatment 1.2 and 1.0 cm.

The article presents the results reached in our study of the influence of mineral fertilizers and growth regulators on symbiotic capacity of field pea in the conditions of Western Forest-Steppe. Experimental part was carried out during 2016-2018 on the field of the TPC Podilya at the SAEUP, the typical black soil, characterized as deep, low-humus, and heavy gravel on forest-like loams. The results indicate that the productivity of field pea largely depended on the effective interaction of the host plant and nodule bacteria. Application of phosphorus-potassium fertilizers and small doses of nitrogen fertilizers improved the biological fixation of nitrogen. Spray application of growth regulators at the budding-flowering phase continued the functioning of the red pigment of synthesized leghemoglobin in the nodules. The positive effect of mineral fertilizers and growth regulators on the symbiotic potentials of field pea plants was confirmed. The total symbiotic potential characterizes the state of legume-rhizobium symbiosis. The duration of active functioning of nodules on pea roots and their ability to fix biological nitrogen during the growing season define the magnitude of the active symbiotic potential. During the growing season, the total symbiotic potential indicators were the highest for the Chekbek variety and amounted to 13.1 thousand kg*days/ha (after application of N30P30K45 with the Vympel growth regulator). After application of the same combination of mineral fertilizer and growth regulator, the Gotovsky variety demonstrated - 10.6 thousand kg*days/ha, the Fargus variety – 10.0 thousand kg*days/ha.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

In the conditions of the western Forest-steppe, leguminous crops, including sowing peas, are the main and most important source of vegetable protein, which solve the biological and ecological problems of modern agriculture in Ukraine. The article presents the main research results on the study of the effect of mineral fertilizers and growth regulators on the formation of the sowing peas productivity in the conditions of the western Forest-steppe. The field trifactor experiment was laid in the ten-field crop rotation in Podillia Research Center of State Agrarian and Engineering University in Podilya, during 2016–2018. The field experiment was laid down in the research ten-digit crop rotation. In microstages VVSN 55-65 (budding – flowering) crops were sprayed with growth regulators PlantaPeg, Еmistim С and Vympel. The studies carried out showed that the individual productivity of plants of the Chekbek variety was the best of all the varieties that were studied. It was found, that high indices of the mass of 1000 seeds were in the variants, where mineral fertilizers were used at a dose of N30P30K45 with the plant growth regulator Vympel. According to this fertilizer composition, the mass indices of 1000 seeds for peas of the Chekbek variety were 266.4 g, and for the Hotivskyi and Fargus varieties – 260.6 g and 238.4 g, respectively. The grain yield of peas is an integrated indicator of the action of all life factors on the plant organism during its growth and development. To a large extent, it depends on the biological characteristics of the variety, the supply of moisture and nutrients to the plant, technological methods of cultivation, as well as natural and climatic conditions. In our studies, the crops, fed with mineral fertilizers and growth regulators, were significantly less exposed to adverse factors, and the studied technology elements had a positive effect on the productivity of pea grain. The maximum biological yield was for the application of mineral fertilizers in doses of N30P30K45 and the plant growth regulator Vympel. For the varieties of Hotivskyi peas, these indicators were 3.79 t/ha, Chekbek 4.32 t/ha, and Fargus 3.30 t/ha

In Ukraine, the area under garlic is increasing and as of 2020 amounted to 1,100 hectares, due to the high profitability of production and constant demand in both domestic and foreign markets. At the same time, the evaluation of existing and new varieties of winter garlic is important for further growth in yields of this important crop. The aim of the research is to assess the genetic diversity of the studied varieties of winter garlic by ISSR loci and to determine the most productive in the conditions of the Left Bank Forest-Steppe of Ukraine. Winter garlic varieties Duchess, Lyubasha and Hungarian (line 20-16) were used for the research. The highest level of marketable yield (14.1 t / ha) was obtained when growing winter garlic of Lyubasha. The Hungarian variety (Line 20-16) provided a yield of 12.9 t / ha, the Duchess variety 9.4 t / ha. The formation of winter garlic yield by 12.3 % depended on the characteristics of the variety, the influence of the growing season was 87.3 %. Agronomically stable (As ˃ 70 %) was the winter garlic variety Hungarian (Line 20-16) with As = 73.8 %. Based on the above studies, allelic formulas (molecular genetic passports) of winter garlic varieties Hungarian (Line 20-16), Lyubasha and Duchess were formed. In the studied varieties of winter garlic, several amplicons were found, unique within the study group. The UCC812725 and UBC 812902 loci were unique in the Duchess variety, and the UBC 812791 and UBC 842702 loci were unique in the Lyubasha variety. The calculated Nei–Li similarity coefficients indicate a significant genetic similarity of the studied varieties of winter garlic. The Lyubasha and Duchess varieties are genetically closer to each other than the Hungarian varieties (Line 20-16).

The potato is one of the most versatile, accessible and at the same time widespread vegetable crops of the globe, and in particular of the Russian Federation. Today notable can be imagined without it. But despite the plasticity of the potato crop, there are still “white spots” in its production. With late and even return spring and early autumn frosts, the climatic features of Siberia significantly affect the crop’s growing season, preventing it from realising its full potential. Like that of many other crops, potato production is associated with seasonality, and there are often significant losses during cultivation and especially during storage. An important challenge is to protect plants during growth and development by applying innovative, environmentally friendly crop protection and stimulation products. Organomineral growth and development regulators were particularly popular. In the work schemes of application of perspective, organomineral growth regulators in conditions of forest-steppe of Western Siberia were tested and perfected. Their influence on the primary phases of growth and development of potatoes and their maturity, and their influence on biometrical parameters of plants, a phytosanitary condition of crops, a crop capacity, and its safety are established. On average, under the influence of growth regulators Epin-Extra and Zircon, the growing season is shortened by 3-5 days; the spread of diseases is reduced by 1.5-2 times; the yield increases to 8.3 tons per hectare. These studies are confirmed by the calculation of economic efficiency. Thus, the use of these growth regulators provides the level of profitability of production up to 252%.

In the garden of Omsk Agrarian Scientific Center, located in the southern forest-steppe of Omsk region in 2018-2020 research has been carried out with the aim of studying the features of the influence of various stimulants of root formation during the propagation of clonal pear rootstocks by green and lignified cuttings. The soil is meadow-chernozemic medium loamy with a pronounced sandy fraction, the reaction of the soil solution is close to neutral. The object of research is clonal pear stocks PG 2, PG 12, PG 17-16. Rooting of green and lignified cuttings was carried out in a greenhouse with a film coating with an artificial fogging installation. The substrate is a mixture of sand and peat (1 to 1). Planting scheme of cuttings 5×5 cm, in four replicates (50 pcs.), Placement is randomized. Kornevin (powdering of sections), and Ribav-extra, control – water (duration of exposure - 16 h) were used as stimulants of root formation during green cuttings. When propagating by lignified cuttings, cornevin (0,1%) and ribav-extra (0,01%) were used; water was used as control (exposure duration - 16 h). Clonal pear rootstocks tolerated the winter conditions of the study years relatively favorably. The exception was winter 2019-2020, the total degree of freezing was 1 point in the PG 2 and PG 17-16 rootstocks, and 5 points in the PG 12 rootstock (90% plant loss). The beginning of the growing season in 2018 was marked on May 22-23, in 2019 - May 5-6, in 2020 - April 18-19. In 2018-2019, green cuttings were carried out on June 20, in 2020 - on June 10. Earlier terms of cuttings in 2020 are explained by the rapid regrowth and lignification of the shoots (hot weather and lack of precipitation in the first months of the growing season). In the control, massive root formation was noted after 6 weeks. The treatment of cuttings with growth stimulants promoted the acceleration of root formation, which was observed after 4 ... 5 weeks. On average, over the years of research, rooting rate when using Kornevin, in comparison with control, increased by 13 ... 18%, Ribav -extra - by 10 ... 13%. The rootstock PG 12 is characterized by a higher rooting Kornevin of green cuttings (51.5 ... 56.5%) than that of PG 2 (47.7 ... 49%) and PG 17-16 (41.7 ... 44.3%). Rooting rate when using Kornevin was 50%, Ribav - extra 47%. PG 12 is the only rootstock under study in which rooting of lignified cuttings is observed: in the control 24%, when using preparations 44.5 ... 52%

Purpose. To reveal features of formation of productivi­ty and quality of commercial products of parsnip (Pastina­ca sativa L.) depending on ways of application of growth regulator Bioglobin in the conditions of the Western Fo­rest-Steppe of Ukraine. Methods. Field, laboratory, analytical and statistical. Results. With the introduction of the growth regulator Bioglobin, the mass of a parsnip root increased from 207 to 249 g (control – 196 g). A large mass of roots – 244 and 249 g – was observed when proces­sing seeds with Bioglobin (0.5 l/ha) + foliar fertilization in two stages and seed treatment with Bioglobin (0.5 l/ha) + foliar fertilization in three stages, which is higher than control (without treatment) for 48 and 53 g, or 20.4 and 27.0%, respectively. High yields of roots of parsnip cultivar ‘Stymul’ were obtained in 6 and 8 variants of the experiment – 53.5 and 54.7 t/ha, yield increase was 10.3 and 11.4 t/ha, or 23.8 and 26.4% in accordance. There is a strong relationship (r = 0.98 and 0.99) between yield and weight of parsnip root. Qualitative indicators of root crops (dry matter, amount of sugars and vitamin C) improved with increasing number of treatments with growth regulator Bioglobin. There is a tendency to decrease the concentration of nitrates in roots with increasing number of treatments with growth regulator. In general, the content of nitrate nitro­gen in the roots in all variants of the experiment did not exceed the threshold limit value (TLV) (400 mg/kg of raw weight). Conclusions. An increase in the number of treatments for parsnip seeds and foliar application of the growth regulator Bioglobin ensured an increase in the mass of root crops, an increase in their yield, marketability and an improvement in the quality of commercial products. The highest yield – 54.7 t/ha of marketable root crops of parsnip variety ‘Stymul’ was obtained when processing seeds with Bioglobin (0.5 l/ha) + foliar feeding in three stages.

The article presents the results of a multi-year research aimed at establishing the influence of plant growth regulators and doses of nitrogen top dressings on the growth, development, productivity and technological qualities of Grom variety of soft winter wheat grain of the FSBSI «SGC named after P.P. Lukyanenko» selection. The results of the research revealed that the duration of the entire growing season and interphase stages of winter wheat development was largely influenced by weather conditions in the spring-summer period. Application of nitrogen top dressing in the «tillering-beginning of stemming» phase promoted the formation of more vigorous winter wheat plants with an increased tillering coefficient. The best indicators were obtained in options where «Biosil» preparation was used. The most intensive increase in the aboveground mass of winter wheat throughout the growing season occurred with the use of the «Alfastim» growth regulator; it was followed by «Novosil» preparation. The cultivation of crops with growth regulators increased the productive plant stand by 7,8–15,2%, but didn’t have a significant effect on the other elements of the crop structure. Application of nitrogen fertilizer in doses of N35+N35 иN35+N35+N20 when treated with «Novosil» growth regulator provided a high yield – up to 7,13 t/ha. Slightly lower was the yield with the use of «Alfastim» preparation compared with «Novosil». In the option without nitrogen fertilizers the fifth class grain was formed, and the treatment of winter wheat crops with the studied preparations increased the class of grain to the fourth one, due to an increase in the content of protein and gluten in the grain. Similar changes were also noted when nitrogen was added to the top dressing at doses of N20 + N20 and N35 + N35. Spring nitrogen fertilization of winter wheat crops in the heading phase contributed to an increase in the grain class.
