Abstract The paper aims to assess the use of various forms of nitrogen fertilizers (seedbed dressing and foliar dressing) in barley cultivation in the steppe and forest-steppe zones of the Omsk region. The research objects were barley, nitrogen fertilizers, ordinary steppe chernozem, forest-steppe meadow chernozem. Variety – Sasha. The most agronomic efficiency in the steppe zone, 5.52 kg of grain derived from 1 kg of fertilizer nitrogen, was yielded in response to the use of N30 in the form of ammonium nitrate and urea during sowing. N60 (seedbed dressing + foliar fertilizing) resulted in a reimbursement of 1 kg of fertilizer active agent in the maximum amount of 4.44 kg (ammonium nitrate + urea, ammonium nitrate + UAN). The greatest reimbursement in the forest-steppe zone, 11.11 kg of grain from 1 kg of fertilizer nitrogen, resulted from the use of N30 in the form of ammonium nitrate and UAN during sowing. N60 (seedbed dressing + foliar dressing) resulted in a reimbursement of 1 kg of active agent in the maximum amount of 11.11 kg of barley (ammonium nitrate + urea). The richest harvest of barley was taken in following seedbed dressing and supplementary fertilizing applied together during the growing season in a total dose of 60 kg/ha. In this case, the yield did not reliably depend on the forms of nitrogen fertilizers used; a greater effect resulted from nitrogen fertilizers in the forest-steppe zone.

Nitrification inhibitors have been used to enhance the efficiency of nitrogen fertilizers. This research evaluated the effectiveness of nontreated urea ammonium nitrate (UAN) at 0, 67, 135, 202, and 270 kg N ha-1 as well as UAN treated with nitrification inhibitors (pronitridine at 9.4 and 18.8 L ha-1 or nitrapyrin at 0.5 kg a.i. ha-1) to enhance N uptake and increase yield of corn (Zea mays L.). The study took place from 2012-2014 in upstate Missouri on a claypan soil. During the experiments, environmental conditions (high, medium, and low yielding years) affected corn response to pronitridine and nitrapyrin. In general, UAN plus pronitridine at 9.4 L ha-1 had similar effects on corn compared pronitridine at a higher (18.7 L ha-1) rate. During a high-yielding year (2014), in order to produce yields equivalent to 67 kg N ha-1 plus pronitridine at 9.4 L ha-1 or nitrapyrin, UAN needed to be increased 14 to 19%. Similarly, the amount of nontreated UAN needed to be increased 8 to 11% for yields to be equivalent to UAN at 135 kg N ha-1 plus pronitridine at 9.4 L ha-1 or nitrapyrin. Grain N removal and agronomic efficiency was highest with pronitridine at 9.4 L ha-1 and nitrapyrin combined with 67 and 135 kg N ha-1, respectively. This research indicates that pronitridine was as effective as nitrapyrin when added to a pre-emergence application of UAN placed between the rows in a dribble band.

Induced Changes

Balsam woolly aphids were reared on young grand fir trees maintained in controlled environment or outdoors. Solutions of various nitrogen fertilizers were applied repeatedly to the trees and the effects on aphids and bark amino acids were studied. On trees fertilized with ammonium nitrate or a sequence of compounds, aphid population growth was less than on trees fertilized with urea or potassium ammonium nitrate. On urea-fertilized trees, populations multiplied 16.5 times in five generations, compared with a 5.7-fold increase on unfertilized trees and a 1.4-fold increase on ammonium nitrate-fertilized trees. These differences resulted from effects of these nutrients on aphid life history. Urea promoted aphid establishment and reproduction, whereas ammonium nitrate affected these processes, as well as survival, adversely. The highest establishment and survival rates resulted from potassium ammonium nitrate.These differences may be related to fertilizer-induced changes in the amino acid diet of the aphid. Thin layer electrophoresis and chromatography revealed that urea, ammonium nitrate, and calcium nitrate each increased arginine concentrations in the bark, the highest levels resulting from ammonium nitrate. Traces of phenylalanine and asparagine, found in other treatments, were absent from trees fertilized with ammonium nitrate during June.

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 aim of this research is to estimate the influence of a bioeffector (BE) application on dry matter yield and nutrient content (P, K, Ca, Mg, S) in maize (Zea mays L.). Between 2014 and 2016, a field experiment with silage maize as a testing plant was realized on sandy loam Cambisol. The application of Pseudomonas sp. in combination with phosphorus (rock phosphate (RP) or triple superphosphate (TSP)) and nitrogen fertilizers (ammonium nitrate with urea, ammonium nitrate with limestone, calcium nitrate or ammonium sulfate with a nitrification inhibitor) and with different application strategies was studied. The effects of a bioeffector application on the increase of dry matter yields were not confirmed. An important influence on the BE application and its activity was probably those of soil and site conditions and competition of the researched microorganisms with other present microorganisms. Higher yields of dry matter were shown in treatments where P fertilizers were applied. There was almost no difference between the application of RP and TSP. This could be caused by the fact that the soil had a slightly acidic pH value. In this case, the RP showed similar results to the TSP. The application of bioeffector significantly increased Mg, K and S contents in maize above-ground biomass. An increase of the Ca content was almost significant and a tendency towards a higher average content of phosphorus was also recorded.

The article considers the issue of productivity and economic efficiency of the use of slow-acting nitrogen fertilizers obtained using the ”Si” technology of winter wheat. The studies were carried out in 2014–2017 in the northern forest-steppe zone of the Tyumen region on the experimental field of the Agrotechnological Institute of the GAU of the Northern Trans-Urals. increased winter wheat grain yield. Winter wheat productivity according to the studied options on average over the years of research ranged from 3.36–3.41 t/ha, which is higher than the control about the option of 0.27–0.32 t/ha. The economic efficiency of the fertilizers used was determined by the cost of increasing the crop and the cost of obtaining it. Analysis of economic efficiency showed that when sowing the nitrogen fertilizer, urea encapsulated by Si technology (30 kg/ha d.v.) received the highest profitability – 81.68 %. The resulting conditionally net income in this option amounted to 1663.4 rub/ha. In the sixth version of the experiment (encapsulated urea according to the ”Si” technology (60 kg/ha a.v.) + KCl (30 kg/ha a.a.) + P2O5 (40 kg/ha a.a.)) profitability – 76.0 %. Obtained conditionally net income in this embodiment amounted to 1222 rubles/ha. The return on fertilizer use ranged from 4 to 85 %.

The article presents the results of applying the methodology for assessing the quality of land to ensure effective agricultural production. On the basis of correlation-regression analysis, indicators were chosen, that ensure high and medium tightness of communication, necessary for the formation of effective use of land by agricultural organizations in the context of municipal districts of Omsk region. Using the variation coefficient, which shows the relative measure of the spread of data, a set is defined. Based on the selected indicators, in accordance with the scaling factor scale, an index assessment of the conditions was carried out, which showed that the agricultural organizations of the steppe and southern forest-steppe zone of Omsk region are most favorable for natural conditions and land properties. Not so definitely, but, basically, the situation of advantage in the supply of labor resources to organizations of the steppe and southern forest-steppe zone was confirmed. However, in terms of the availability of the main means of production, the best indicators are for organizations of the southern forest-steppe zone, which in the end provided them with an advantage in the anthropogenic conditions of using the land in front of other zones. In general, the overall quality of land use conditions in the areas of the southern forest-steppe was higher than in other areas. This has had a decisive impact on the level of efficiency of agricultural land use in the districts of the region. In general, the areas of the southern forest-steppe have a higher efficiency of land use and the efficiency of crop production.

The effect of fertilizers application by the method of fertigation with drip irrigation during seabuckthorn growing in the nursery was estimated. The research has been carried out in the nursery field, in the forest-steppe zone of Altai Krai in 2019-2020. The soil on the experimental plot is gray-forest, reaction of the medium pH 5.8-5.9. The content of nitrate nitrogen was in the range of 7.8-9.8 mg/kg in the control variant; after fertilization, these values rose to 87.9 mg/kg. Nitrate nitrogen was determined by the ion-selective method. The soil at a high level is provided with mobile phosphorus 342-453 mg/kg and potassium 181-355 mg/kg - determined according to Chirikov. The research object – is one-year-old seabuckthorn trees of Altaiskaya cultivar. Urea was applied as nitrogen fertilizer in three rates of the active ingredient (40, 60, and 80 kg/ha). Double superphosphate (30 kg/ha) and potassium chloride (30 kg/ha) were used as the background. The soil moisture level was maintained at 70-80% of the LWC. The effectiveness of fertilizers was assessed by the marketable yield of two-year-old seedlings and their quality indicators. The measurements were carried out in the fall, after excavation. According to the values of the parameters of the aboveground part, the dose of nitrogen fertilizer of 60 kg/ha turned out to be the best option. At the same time, the seedlings had a height of 89.5 cm, the number of branches was 4.4 pcs., The diameter of the trunk was 8.4 cm, which is 15.4 cm, 0.5 pcs. and 1.3 mm above the control. The yield of seedlings of the first commercial grade in the experiment averaged 164 pieces. (82.8%), the maximum is marked on the N60P30K30 variant 190 pcs. (93.8%). Control without the use of fertilizers in all respects is significantly inferior to options with fertilizers. Thus, the use of nitrogen fertilizers has a positive effect on the quality of the seabuckthorn planting material. As a result, the utilization of nitrogen fertilizers has a positive effect on the quality of the seabuckthorn plant material, while higher concentrations become unprofitable compared to low ones due to high costs and insignificant differences in the quality of trees

Purpose. Determine the optimal rate of nitrogen fertilizers for fertilizing energy plantations of willow  before the start of the second three-year cultivation cycle in the Central Forest-Steppe of Ukraine. Research methods. Field, analytical, statistical. Results and discussion. Appling of ammonium nitrate contributed to the active beginning of the growing season and the increase in the plant mass in hight. At the end of the first year of vegetation, the tallest plants were formed in variety ‘Tora’ using N70 – 4.67 m, which is more than in the control version (without fertilizer) by 0.71 m, or 16%. For N35, the average plant height was 4.32 m, which is 8% more than the control. The formation of more tall plants to restore more nitrogen was found in the variety’Ternopilska’. Hight of annual plant of this variety in control was 3.68 m, for application N35 – 4.08 m, and for dose N70 – 4.24 m. At the end of the second growing cycle, the average height of plants of the variety ‘Tora’ in  control variant was 6.29 m. The highest plants with the distribution of ammonium nitrate in the maximum dose (N70) were 6.78 m, which is more than in control variant by 8%. For the application of N35, the height of plants of the plantation was 6.52 m and 5.79 m. In this case, the decrease in the share affects the height of plants up to 15.4%, and the share affects the varietal characteristics of growth up to 82.9%. Also nitrogen had a positive effect on biomass growth. The yield of dry biomass of three-year-old energy willow plantation in the other part of cyclic production under control (without fertilizers) was 65.3  t/ha (21.8 t/ ha/year) of dry biomass in ‘Tora’ variety, and 55.6 t/ha (18.5 t/ha/year) in ‘Ternopilska’ variety. In the variants with the use of ammonium nitrate in the dose of N35, the indicator increased due to the control in variety ’Tora’ by 2.8 t/ha and by 3.7 t/ha in the variety ’Ternopilska’. Increasing the nitrogen dose to N70 increases the yield of dry biomass in the varieties’Tora’ and ’Ternopilska’ by 8.8 t/ha and 9.3 t/ha, respectively, compared to the control. Conclusions. The application of ammonium nitrate and varietal characteristics have a significant impact on the yield of energy biomass of willow. Of the two studied varieties of willow on chernozem soil of the Central Forest-Steppe of Ukraine, the variety’Tora’ was noted for more intensive growth and higher productivity during the second three-year growing cycle. Plants of both varieties are characterized by higher yields for nitrogen application at a dose of 70 kg/ha a.i.
