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 effect of application of different doses and combinations of mineral fertilizers in field crop rotation on the content of basic nutrients in plants, economic and relative removal of winter wheat, corn, spring barley and soybeans was studied. Soil - Luvic Chernic Phaeozem. The scheme of the experiment includes 11 variants of combinations and separate application of mineral fertilizers and, including the variant without fertilizer. It was found that the level of nitrogen content of easily hydrolyzed compounds in the soil significantly affects its content in the grain of spring barley, corn, soybeans (R2 = 0,92–0,93), less - winter wheat (R2 = 0,63). The content of mobile phosphates in the soil has almost the same effect on its content in the main and non-commodity part of the crop, regardless of the crop (R2 = 0,39–0,70). The smallest relationship between the content of mobile compounds in the soil and in the crop was in potassium, but in soybean seeds and straw of spring barley and soybeans it was clearly traced (R2 = 0,53–0,68). Nitrogen (64,4–149,9 kg / ha) has the largest share in the economic extraction of nutrients with grain and seed yield, followed by phosphorus – 21,1–51,4 kg P2O5/ ha, depending on the crop. On the formation of the crop unit of marketable and the corresponding amount of non-marketable crop products absorb nutrients in the following ratio N : P2O5 : K2O: winter wheat – 1 : 0,4: 0,7; corn – 1 : 0,3 : 0,8; spring barley – 1 : 0,4 : 0,7 and soy – 1 : 0,4 : 0,4. With the non-commodity part of the crop, nitrogen with corn stalks returns to the soil from economic removal – 28–36 %, phosphorus with soybean straw (47–54 %) and potassium with winter wheat straw and corn stalks – 74–80 %, depending on the experiment variant.

The influence of long-term application of different doses and ratios of mineral fertilizers in field crop rotation on the content of basic nutrients in grain and straw of spring barley has been established. The study was held in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine. The relative nutrients removal by spring barley depending on the doses of different types of fertilizers and their combinations in the field crop rotation is calculated. It is shown that the content of basic nutrients in the harvest of spring barley (grain and straw) significantly depends on the content of their mobile compounds in the soil. This is especially true of nitrogen and less of potassium. Economic removal of nutrients from the grain harvest of spring barley depends on the doses of fertilizers in the field crop rotation and the ratio of nutrients in them. The largest share is nitrogen (65–122 kg / ha), followed by K2O - 47–92 and P2O5 26–51 kg / ha. From 1 ton of grain and the corresponding amount of straw, spring barley of the Commander variety removes 19.2–22.4 kg of nitrogen, 7.8–9.2 - P2O5 and 14.0–16.8 kg of K2O from the soil, depending on the fertilizer and saturation of field crop rotation with different types of fertilizers. Straw is an important source of soil organic matter reproduction and the return of nutrients used for crop formation. Depending on the system of fertilization, 17–25% of nitrogen, 25–30% of phosphorus and 68–69% of potassium are returned to the soil with spring barley straw via economic removal. It is specified that spring barley of the Commander variety absorbs N, P2O5 and K2O in the following ratio: 1: 0,4: 0,3 to form a unit of grain yield and the corresponding amount of straw in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe.

During 2000–2018, the results of the application of organic and mineral fertilizers in dynamics and their effect on the content of humus and nutrients in the soils of the Zaporizhzhya region were reviewed. To control the state of soil fertility use the calculation of the balance of humus and nutrients. This makes it possible to determine the extent to which the application of nutrients with fertilizers covers their removal by crop yields. Negative tendencies have been identified, which have led to the deterioration of soil fertility in the Zaporizhia region. Measures are proposed to achieve a deficit-free balance of humus and nutrients. On average, in 2000–2018, the level of mineral fertilizer application in the Zaporizhia region remained low – 38 kg/ha (nitrogen – 28 kg, phosphorus – 7, potassium – 3 kg), and manure – only 0.2 t/ha. According to the results of agrochemical certification of agricultural lands, the dynamics of changes in the content of humus, easily hydrolyzed nitrogen, mobile compounds of phosphorus and potassium over the past 18 years has been determined. The average weighted content of humus in the soils in the VIII round was 3.44 %, IX – 3.52, X – 3.40, XI (2016–2018) – 3.57 %, which indicates the stability of this indicator. The weighted average nitrogen content, which is easily hydrolyzed during all rounds, has close values (83.6–90.3 mg/kg) and corresponds to a low level of its supply. The content of mobile phosphorus compounds during the VIII – IX rounds was quite stable (97.1–101.6 mg/kg), and in the X–XI rounds there was even an increase to 123.3–123.4 mg/kg. The phosphorus regime of soils is stable and corresponds to the increased level of security, except for the ninth round (average). Potassium regime of the soil for eighteen years also remains stable and refers to a high level of security (159.6–176.8 mg/kg). The balance of humus and nutrients in the soils of the region remains negative. There is a tendency of positive changes if we compare the results for the first (2003–2014) and second (2003–2018) periods. Thus, to achieve a positive balance of humus it is necessary to apply 2 t/ha of straw (+400 kg/ha), 20 kg/ha of nitrogen fertilizers and 6.4 t/ha of manure, and in 2003–2018 – respectively 2 t / ha straw (+400 kg/ha), 20 kg/ha of nitrogen, 5.8 t/ha of manure. Key words: soil, balance, dynamics, humus, fertility, organic and mineral fertilizers.

Control Analysis

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %.

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 influence of long-term application of potassium-deficient fertilizer system in the field crop rotation (winter wheat, corn, spring barley, soybeans) on podzolic heavy loam black earth of the Right-Bank Forest-Steppe of Ukraine on potassium content in plants, its costs for formation of one unit of the harvest was determined; potassium balance was calculated and the effectiveness of different doses of potassium fertilizers was comprehensively assessed. It was found that the potassium content in grains and seeds of agricultural crops under the influence of potassium fertilizers varies by no more than 8%, while in straw and stalks - by 10-24% depending on the variant of the experiment. It is shown that the non-grain part of the crop contains a significant part of potassium - 50-80% of economic removal depending on the crop. It is calculated that if it is left in the field for fertilizer in the variant of the experiment Basis + K80, it compensates for the consumption of potassium by 71%. By applying K40 and K80on the basis of applying N110P60 and leaving the non-commodity part of the crop in the field for fertilizer, the balance of potassium in the soil is formed positive with intensity of 111 and 212%, respectively. According to the index of complex assessment, which takes into account seven indicators: payback of 1 kg of mineral fertilizers; additionally conditionally net profit; net energy profit; humus balance and intensity of nitrogen, phosphorus and potassium balance, the best variant of the experiment is application of N110P60K40 per 1 ha of field crop rotation area. This indicates the possibility of a temporary reduction in the dose of potassium fertilizers in field crop rotation on podzolic heavyloam black earth in the Right-Bank Forest-Steppe of Ukraine

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.

In order to maximize the potential of productivity of spring barley varieties, it is important to optimize the conditions for plant growth and development, which are, first of all, provided by the latest intensive agricultural technologies, which provide for the correct placement of crops in crop rotation after the respective precursors; optimal supply of plants with nutrients, taking into account their content in the soil; fractional application of nitrogen fertilizers during the growing season by phases of growth and stages of organogenesis; the use of retardants, integrated protection of plants against weeds, pests, diseases, timely and quality implementation of all agrotechnical measures. Research to study the effectiveness of different terms of spring barley sowing and doses of nitrogen fertilizers were conducted during 2018 - 2019 in the conditions of the research field of VSAU v. Agronomichne of Vinnytsia region on gray ashed soils. Weather conditions during the years of the research differed from the average long-term data with high temperature conditions and low rainfall, and accordingly the most favorable year for the growth and development of spring barley was 2018. It is shown the 2-years investigation results on study the effect of sowing dates and nitrogen fertilizations on productivity elements and quality indexes of spring barley grain under conditions of Right-Bank Forest-Steppe on gray forest soils. Accordingly, the highest levels of harvest of barley cultivars at different sowing dates were obtained under conditions of 2018. t should also be noted that the delay of sowing by 6 days in the years of research leads to a decrease in the yield level on average for all varieties by 0,42 – 0,64 t / ha, and a delay of 14 days leads to a decrease by 1,37 – 1,80 t / ha. The use of nitrogen fertilizers leads to an increase in the yield level of both cultivated varieties, and the highest crop yields of the Svarog variety were obtained in the experiment where the background + N60 was applied in the foliar fertilization (4,87 t / ha), and the lowest respectively in the control variant 3,16 t /ha, in the Armax variety a similar situation is observed, however, with lower indicators respectively 4,54 and 3,06 t / ha. The lowest values of protein content in the grain were obtained in the control variant where only N17 P17 K17 was applied to rows when sowing, and the use of nitrogen fertilization leads to an increase in this indicator and the highest values obtained in the variant of experiment 4, where Background (N17 P17 K17) + N60 in the foliar fertilization on the feeding phase of the tube exit.
