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.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The article presents the results of field research conducted in 2018-2019 on leached Chernozem of the Volga forest-steppe. The objects of research are varieties of spring wheat-Tulaykovskaya 10, Yoldyz and Tulaykovskaya 108. At different seeding rates of 5.0 and 5.5 million germinating seeds per ha, the effect of mineral fertilizers on 1 ha was studied. They were represented by a complete mineral fertilizer (azofoska) and fertilizing with a mineral nitrogen fertilizer in the tillering phase at doses of 30, 60 and 90 kg of AD/ha against this background. Analysis of the yield of spring wheat varieties indicates that the harvest of grain variety Yoldyz in variants with a seeding rate of 5.5 million germinating seeds per ha against the background of the application of ammonium nitrate at a dose of 60 kg of DA (2.52 t/ha) was superior to other varieties Tulaykovskaya 10 and Tulaykovskaya 108 (2.51 and 2.46 t/ha). The maximum increase in seed productivity when adding ammonium nitrate in the tillage phase of the crop was in Tulaykovskaya 10 variety (0.34 t/ha), the lowest in the Yoldyz variety (0.06 t/ha) compared to the variant with amofoska application in the pre-sowing cultivation. When increasing the doses of nitrogen fertilizers there was an increase in the water content of all the studied varieties by 1-3 PCs. While increasing the seeding rate from 5.0 to 5.5 million germinating seeds per 1 ha the number of grains in the ear changed on average for varieties by 1-2 PCs. Of all the studied varieties, the largest mass of 1,000 grains was in the Yoldyz variety (40.56 g) after azofoska application in the presowing cultivation + N60 during tillering at a seeding rate of 5.0 million germinating seeds per 1 ha, the smallest in the Tulaykovskaya 108 variety (37.87 g) after azofoska application at a dose of 0.15 t/ha at a seeding rate of 5.0 million   germinating seeds per 1 ha.

The Individual

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 the Forest-Steppe Zone of Ukraine, a study was carried out to establish the effect of mineral fertilizers and drip irrigation on the yield of dry raw material. It was found that irrigation significantly increases productivity of althaea, by eliminating the deficit of soil moisture in critical periods of growth and development. The yield increase caused by the use of drip irrigation in the first year of vegetation of the crop was 1.27–1.98 t/ha for dry grass, for leaves — 0.69–1.17 t/ha, for roots 0.22–0.39 t/ha. For the second growing season, the yield increase was: 1.52–4.7 t/ha for grass, 0.46–1.35 t/ha for leaves and 1.5–2.76 t/ha for roots. It was also found that increase of the mineral fertilizers main application dose caused increase of the yield. The highest yield of dry raw material of the culture was obtained in both the first and second years of the growing season with the introduction of N180P180K180. With the application of mineral fertilizer at a dose of N180P180K180 under conditions of drip irrigation, the yield of dried althaea grass was 8.09 t/ha, leaves — 3.88 t/ha, roots — 3.08 t/ha, which exceeded the option without fertilizers and without irrigation by 4.08 t/ha for grass, 2.04 t/ha for leaves, 1.44 t/ha for roots. The highest yield was obtained in the second year of vegetation using the variant with the application of the highest dose of mineral fertilizers under drip irrigation, where the yield of dry grass was 15.78 t/ha, leaves — 4.42 t/ha, roots — 6.24 t/ha. On the plantation of the second year of vegetation in the variant without irrigation and without fertilizers, the yield of raw materials was the lowest. It was 6.85 t/ha for grass, 1.88 t/ha for leaves and 2.12 t/ha for roots.

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 results of a field experiment held on podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine, studying the effect of various fertilization systems on the water-holding capacity of sugar beet, are presented. It was found that the change in nitrogen, phosphorus and potassium nutrition has a different effect on this indicator when closing the leaves of sugar beet plants between rows and during the harvest time. Half-dead cattle manure KRS on straw bedding aw well as mineral fertilizers, namely aqueous ammonia, ammonium nitrate, granular superphosphate, mixed potassium salt, potassium chloride, ANP fertilizer grade A and liquid complex fertilizer grade 10–34–0 were used during the experiment. Manure was applied at a dose of 40 t / ha and mineral fertilizers – N120Р120К120. Fertilizers were applied in August during fall plowing, as well as in late autumn (at the end of October) together with moldboard-free loosening of the soil to a depth of 14–16 cm and in spring –under pre-sowing cultivation. The dynamics of the intensity of water return was monitored by cut sugar beet leaves under conditions of rapid natural evaporation by weighing them every 0.5, 1 and 2 hours (according to Arland's method). It was found that the leaves of sugar beet, both with insufficient and unbalanced nitrogen nutrition, have a weak water-holding capacity during the growing season. Improving phosphorus nutrition, especially when applying liquid complex fertilizer grade 10–34–0, helps increase the water-holding capacity of sugar beet plants throughout the growing season. Replacing potassium chloride with potassium salt mixed as part of a complete mineral fertilizer significantly increases the water-holding capacity of sugar beets due to the better provision with sodium. This is particularly evident in the second half of the growing season. With the age of sugar beet plants, a distinct decrease in the intensity of water loss is observed regardless of fertilization, which can be explained by an increase in the content of bound water due to a rise of the amount of dry matter.

Were described results of study effect of fertilizers and seed inoculation on productivity formation pea varieties with leafless morphotype of leaves on typical black soils of northern Forest-Steppe Right-Bank Ukraine. Research was conducted in 2014˗2016’s at field experiment at «Agronomic Research Station and in laboratory of analytical research in the department of Plant growing NULES of Ukraine. The purpose of the study was to determine the features of formation of efficiency of pea varieties with leaves whiskered morphotype depending on fertilizer and seed inoculation in the northern forest-steppe of the Right-Bank Ukraine. At the day of sowing pea seeds were treated by suspended biopreparation Ryzohumin and biological preparation Hetomik. Mineral fertilizers were applied according to the experimental scheme: on the D1-D6, options nitrogen fertilizers - in seedbed preparation, phosphorus-potassium - the main processing; on D7-D12 variants on the background of complete mineral fertilizer a foliar fertilizer. Was conducted feeding by the stages growth and development of plants BBCH 12−13, 55−59, 61−71. In average in years of study plant density of variety Tsarevych varied within 87,7−105,3 (without inoculation) and 91,7−109,3 (with inoculation) plants/m2. Variety Deviz showed the similar dependence and in experiment with­ out inoculation plants density was within 86,7−102,3 plants/m2 and depended from the variant of fertilization, in inoculating seeds − 90,7−106,3 plants/m2 respectively. Basing on the obtained data, we can note a positive effect of seed inoculation in conjunction with chemical fertilizer Hetomik on survival pea plants during the growing season. It was established that increasing in grain weight per plant significantly depends from feedings by nitrogen and phosphorus fertilizers by the stages growth and development of plant, and inoculation of seeds. Thus, in variants of experiment, where was used seed inoculation and was conducted foliar feeding by nitrogen and phosphorus fertil­ izers (D7−D9) grain mass in variety Deviz at 1,32 g/plant exceeded variant D1 (without fertilizers), and in variety Tsarevych - at 1,18 g/plant respectively. With inoculation of seeds was increased number of beans on the plant – up to 7, 33 (D9) in variety Deviz and to 8, 67 (D2) pcs/plant in variety Tsarevych. The weight of grain from the plant at variety Deviz in variants D7–D9 exceeded variant D1 on 0‚83 g/plant, at variety Tsarevych on 0‚93 g /plant in variants without inoculation. The maxi­ mum yield at level 4‚99 tones/ha of variety Tsarevych and 4‚40 t /ha of variety Deviz was provided by combination of seeds inoculation and fertilizers. Found that optimal growth and development of pea plants variety Tsarevych was reach with application N30P90K90 (D6), and of variety Deviz – N30P60K60 (D12) with three foliar feedings at stages of growth and development of plants.

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.
