description Objective. Study the competitiveness, complementarity and symbiotic activity of a new strain of chickpea nodule bacteria Mesorhizobium ciceri ND-64, study the influence of seed inoculation on the productivity and yield of chickpea varieties of Ukrainian selection under their cultivation in different soil and climatic zones of Ukraine. Methods. Serological, gas chromatography, field experiment and statistical. Results. The use of a new strain of M. ciceri ND-64 for pre-sowing bacterization of chickpea seeds of varieties Skarb, Admiral, Odysei, Budzhak, Triumf and Pamiat upon growing in field experiments in the Steppe zone against the background of the local population of nodule bacteria contributes to a significant increase in nitrogen-fixing nodules by 5 % to 67 %, an increase in the mass of nodules by 10 % to 67 % and nitrogenase activity 26 % to 150 % compared with the positive control (inoculation with the reference strain of M. ciceri H-12). The use of M. ciceri ND- 64 for pre-sowing bacterization of chickpea seeds under cultivation in the Steppe zone of Ukraine also had a positive effect on increasing the yield of chickpea — by 4 % to 18 % compared to the positive control. Inoculation with a new strain of chickpea seeds of varieties Skarb, Triumf and Pamiat contributed to the formation of higher number of nodules (by 57 % to 89 %), increaseed mass of nodules (2.2–2.9 times) and their nitrogenase activity (2–4 times) compared with the positive control upon cultivation in the Polissia zone on the fields where there is no population of chickpea rhizobia. Under these conditions, an increase in structural parameters of yield, the highest gain in chickpea yield, increase in photosynthetic activity and protein content in grain upon inoculation with M. ciceri ND-64 was shown. Obtaining a specific antisera by immunization of rabbits allowed to detect serological relatedness of M. ciceri ND-64, M. ciceri H-101, Mesorhizobium sp. ND-601 and M. ciceri ND-64, isolated from chickpea nodules of Skarb and Pamiat varieties. The competitiveness of M. ciceri ND-64 was determined using the immunological method in the field experiment. It was found that 100 % of nodules have been formed by the representatives of M. ciceri ND-64 in the variant where this serological group was applied for inoculation in the variant with inoculation of the strain M. ciceri ND-64 100 % of the nodules were formed by representatives of this serogroup. Conclusion. M. ciceri ND-64 strain is an effective microsymbiont of chickpea plants, due to its virulence, competitiveness, nitrogen-fixing properties. According to the results of field experiments, it was shown that the new strain, complementary to all studied varieties differing in seed size and shape, type of bush and average height, forms an effective symbiosis for growing chickpea plants both against the active local population of rhizobia and upon the absence of M. cicerі population in the soil. Symbiotic parameters upon seed treatment with suspension of M. ciceri ND-64 exceed these values in the variants with inoculation using the reference strain of M. ciceri H-12 and strains isolated from the nodules of each study variety. Therefore, M. ciceri ND-64 can be used as a bioagent of a microbial preparation for inoculation of chickpea of different varieties in order to form an effective bean-rhizobial symbiosis, increase the productivity of this culture and improve seed quality.

Zemska Institute of Agricultural Microbiology and Agroindustrial Manufacture, NAAS 97 Shevchenka str., Chernihiv, 14035; Ukraine; e-mail: sydorenkochrom@gmail.com Objective. Explore the influence of different organic agrarian backgrounds and their combina- tions on the efficiency of pre-sowing seed inoculation and the development of introduced microor- ganisms in the root spheres of cultivated plants. Methods. Microbiological, gas chromatography, vegetation and field experiment, statistical. Results. In a long-term stationary field experiment on leached chernozem, the stimulating effect and aftereffect of intermediate green manure (lupine) on the manifestation of the efficiency of microbial preparations in the cultivation of potatoes, spring barley, peas and winter wheat in crop rotation was established. The application of 5 t/ha of straw had a weak effect on the efficiency of inoculation, but the combination of straw with green manure provided a significant increase in yields. The positive effect of straw on the efficiency of pre-sowing inoculation develops upon the aftereffects of this fertilizer. The application of 40 t/ha of cattle ma- nure wiped out the efficiency of microbial preparations during the year of direct effect and the first year aftereffect of fertilizer. The negative impact of cattle manure on the action of biological prepa- rations has decreased over time. During the cultivation of crops on the background of “cattle ma- nure + green manure”, the negative effect of cattle manure on the effect of inoculation was signifi- cantly reduced. When the conditions of growing crops were simulated in the vegetation experiments and upon the use of genetically-labelled bacterial strains — biological agents of microbial prepara- tions, it was found that during the year of application of organic fertilizers, the development of Azospirillum brasilense 410Str in root spheres of plants is positively influenced by lupine manure, and cattle manure on the contrary results in significant reduction of the number of azospirilla. The combination of green manure with cattle manure to some extent compensated for the negative im- pact of the latter on the development of the introduced bacteria. During the first year aftereffects of organic fertilizers, these features are maintained in the root zone of spring barley plants. When gro- wing peas, the relationship between the formation of root nodules Rhizobium leguminosarum 31Str and the second year aftereffect of organic fertilizers is not observed. When cultivating winter wheat during the third year aftereffect, organic fertilizers have little effect on the development of Paeni- bacillus polymyxa КВStr in the root spheres of plants. At the same time, in the variants of straw or green manure aftereffects, parameters are slightly higher than the control ones. A slight negative effect on the number of bacteria is still reported in the variant with the aftereffect of manure. Con- clusion. The use of organic fertilizers can significantly affect the efficiency of pre-sowing inocula- tion. The effect and aftereffect of cattle manure negatively affects the development of agronomically beneficial bacteria introduced into the agrocenosis and significantly wipes out the positive effect of biological preparations on crop yields. The use of microbial preparations for inoculation of seeds of agricultural crops for their cultivation on the background of direct effect and aftereffect of inter- mediate lupine green manure, including the combination of green manure with straw provides in- tensive development of introduced microorganisms in root areas of plants and increased yields.

Lutsenko, N. P. Shtanko, I. A. Zemska, 2020 19 Introduction. Soil bacteria and microscop- ic fungi play one of the essential roles in ensur- ing the viability of cultivated plants. The plant, provided with a full complex of microorgan- isms, actively develops roots, gets easily digest- ible nutrients and physiologically active com- pounds from the soil, which has a positive effect on its metabolism and production process as a whole. However, due to significant distortions in the application of certain agronomic tech- niques (unreasonable levels of mineral fertiliz- ers, pesticides, crop rotations, etc.), the compo- sition of groups of microorganisms, which re- quires appropriate correction is distorted in most soils of agrocenoses [1–8]. The optimal solution to this issue is the introduction of selected strains of agronomically beneficial microorgan- isms into agrocenoses using microbial prepara- tions based on them. Analysis of the novel studies and publica- tions. Interest in the use of microorganisms in technologies for growing crops increased in the late 20th century due to the discovery of the phenomenon of associative nitrogen fixation and the ability of certain species of microbiota to actively reproduce in the root spheres of plants [9; 10]. Currently, in various research centres, biological preparations have been de- veloped based on selected active strains of mi- croorganisms for most types of crops, including non-leguminous [11–21]. Today, the production of certain biological preparations has a com- mercial basis. The efficiency of microbial preparations can be impressively high. Numerous field and production experiments, studies in lysimetric units, experiments using 15N, etc. have shown that the efficiency of preparations by their im- pact on the production process can be equivalent to 30–60 kg/ha of mineral nitrogen, 15–30 kg/ha of phosphorus [14; 23]. This is due to the in- crease in the degree of assimilation of the active substance from fertilizers and the improvement of the constructive metabolism of plants, in which mineral compounds in the plant body are actively directed to the synthesis of organic sub- stances [23–25]. A range of studies have convincingly shown the efficiency of pre-sowing inoculation of seeds in the cultivation of crops on mineral agrarian backgrounds, especially low [26–29]. At the same time, the productivity of bacteriza- tion by beneficial microorganisms under organic agrarian backgrounds and their combinations has been insufficiently studied. A typical feature of existing publications is the statement about the effective interaction between microorgan- isms introduced into agrocenoses with organic backgrounds. Thus, it was noted that the maxi- mum diameter of the heads, parameters of their raw and dry weight were registered during the cultivation of lettuce inoculated with azospirilla (GM1M1Az3) on the background of green ma- nure and mulching [30]. It has also been report- ed that the interaction between green manure and inoculation of seeds with Herbaspirillum seropedicae had a positive effect on maize yield, contributing to the increased number of grains and cob weight [31]. There is also evi- dence of high efficiency of agronomically bene- ficial bacteria used against the background of cattle manure. For example, study by Lai et al. [32] showed that although the growth of lettuce in soil fertilized with swine manure when using Azospirillum rugosum IMMIB AFH-6 was sig- nificantly lower than when growing bacterized plants in soil fertilized with chemical fertilizers, but the variant “inoculation + animal manure + 1/2NPK” showed the highest yields and other studied parameters. Studies conducted in Tur- key [33] show that the use of Bacillus cereus, Rhizobium rubi and Brevibacillus reuszeri when growing broccoli on a background of animal manure, contributed to an increase in crop yields by 17.0 %, 20.2 % and 24.3 % and chlo- rophyll content in leaves by 14.7 %, 14.0 % and 13.7 % compared to control (use of manure on- ly), respectively. At the same time, the assimila- tion of macronutrients and micronutrients by plants increased. The use of manure and mem- bers of the genus Azotobacter for inoculation increased the biological yield of wheat grown in the region of Elam (Iran) [34]. Dutta et al. also reported an increase in maize yield with the use of bacteria of the genus Azotobacter and 10 t/ha of animal manure [35]. The review of the literature by Adesemoye and Kloepper [36], when considering the im- portance of agronomically useful microorgan- isms to increase the assimilation of nutrients from fertilizers by inoculate plants, does not dif- ferentiate animal manure and chemical fertiliz- ers as substrates containing chemical elements. The authors consider promising the use of mi- crobial preparations on the background of ani- mal manure. At the same time, our previous ISSN 1997-3004 Сільськогосподарська мікробіологія. 2020. Вип. 32. 20 studies on leached chernozem indicate low effi- ciency of pre-sowing bacterization of crops grown under the effect and aftereffects of cattle manure [37]. Similar results were obtained by T. Miliutenko [38]. However, the reasons for this have not been clearly established yet. Objective: to determine the efficiency of microbial preparations in the cultivation of pota- toes, spring barley, peas and winter wheat under the effect and aftereffects of cattle manure, lu- pine green manure, straw and their combina- tions, to investigate the peculiarities of devel- opment of microorganisms introduced into the root zone of plants. Materials and methods. Field studies were conducted in 2017–2019 in a stationary experi- ment of the Institute of Agricultural Microbiol- ogy and Agroindustrial manufacture of the NAAS on leached chernozem in conditions of short-rotation crop rotation (potatoes – spring barley – peas – winter wheat). The experiment was started in 2009. Agrochemical characteris- tics of the soil: pH — 5.3; humus content — 3.03 %; easily hydrolized nitrogen — 95 mg/kg of soil; mobile phosphorus compounds (P2O5) — 150 (according to Kirsanov); the content of ex- changeable potassium (K2O) (according to Kirsanov) — 108 mg/kg of soil. In the experiment, crops were grown ac- cording to the scheme in 2 blocks — without pre-sowing bacterization and with the use of microbial preparations. Microbial preparations used in the experiment — Biohran for potatoes based on Azospirillum brasilense 410 (TU U 24.1-00497360-006:2009), Mikrohumin based on A. brasilense 410 and physiologically active substances of natural origin (TU U 24.1- 00497360-007:2009), Ryzohumin on the basis of Rhizobium leguminosarum 31 (TU U 24.1- 00497360-003:2007) and Polimiksobakteryn on the basis of phosphate-mobilizing bacteria Pae- nibacillus polymyxa KB (TU U 24.1-00497360- 004:2009) are registered in the Ministry of En- vironmental Protection of Ukraine and approved for use. Potatoes of the Skarbnytsia variety was grown according to the following scheme: 1 — without fertilizers; 2 — straw; 3 — green manure; 4 — animal manure; 5 — straw + green manure; 6 — animal manure + green manure; 7 — N80Р80К80. Spring barley of the Gosia variety was grown according to the scheme (a — first year aftereffect of organic matter): 1 — without fertilizers; 2 — strawа; 3 — green manureа; 4 — animal manureа; 5 — strawа + green manureа; 6 — animal manureа + green manureа; 7 — N60Р60К60. Peas of Hotivsky variety was grown accord- ing to the scheme (b — second year aftereffect of organic matter): 1 — without fertilizers; 2 — strawb; 3 — green manureb; 4 — animal manureb; 5 — strawb + green manureb; 6 — animal manureb + green manureb; 7 — N30Р30К30. Winter wheat of Poliska 90 variety was grown according to the scheme (c — third year aftereffect of organic matter): 1 — without fertilizers; 2 — strawc; 3 — green manurec; 4 — animal manurec; 5 — strawc + green manurec; 6 — animal manurec + green manurec; 7 — N60Р60К60. Similar variants were provided in the block of the experiment with bacterization. Variants with the use of mineral fertilizers were included in the scheme of the experiment as a kind of control, for which high efficiency of biological preparations was expected. Fresh organic matter was added to the pota- toes. Shredded straw in the amount of 5 t/ha was placed into the soil immediately after harvesting winter wheat (in crop rotation — the predeces- sor of potatoes) by disking, and then intermedi- ate green lupine was sown in the appropriate variants. Green-manure mass of narrow-leaved lupine (13–15 t/ha depending on the years of study) was placed in the soil by disking fol- lowed by shallow plowing (15 cm) in late au- tumn (late November). At the same time, cattle manure was applied into the soil at the rate of 40 t/ha in the relevant variants. Mineral fertiliz- ers were applied each year according to the ex- perimental scheme. The area of the experimental plot is 43.2 m2 ISSN 1997-3004 Сільськогосподарська мікробіологія. 2020. Вип. 32. 21 (7.2 × 6.0), the repetition is 4 times. In addition to field studies, in 2020 under the conditions of vegetation experiments, the degree of survival of bacteria, which are the agents of relevant microbial preparations, in the root spheres of plants were determined. 2.5 L vessels were filled with 2 kg of soil each, the humidity was maintained at 60 % of the total moisture content. The soil for vegetation experiments was se- lected in the spring in the appropriate variants of the field stationary experiment, the scheme of which is described above. Therefore, organic fertilizers were not introduced. Accordingly, the soil for the experiment with potatoes contained organic fertilizers applied since autumn, i. e. their effect was direct. Soils for experiments with barley, peas and wheat were characterized by the first, second and third years aftereffects of organic fertilizers, respectively. In the vari- ants with mineral fertilizers, their appropriate doses, equivalent to the field norms, were intro- duced. Bacteria used in the experiment were pre- adapted by the resistance to streptomycin sul- fate, which serves as a convenient genetic mark- er. The method of spontaneously occurring mu- tants by the antibiotic gradient in the digest me- dium described by V. Zibalskyi was used [39]. The selected mutants were resistant to 3,000 μg/mL streptomycin sulfate doses and did not differ from the parental forms in basic phys- iological and biochemical parameters. In the vegetation experiment with potatoes, three fragments of potato tubers of 1 × 1 × × 2 cm3 with the same weight and one bud were planted in the soil in each vessel. Upon planting, each part of the tubers was treated with a sus- pension of Azospirillum brasilense 410Str at a rate of 500 thousand CFU/bud. After germina- tion, the number of potato plants was reduced to two per vessel. In the experiment with barley, 10 seeds were planted in the soil of each vessel. Before planting, they were treated with a suspension of Azospirillum brasilense 410Str at a rate of 225 thousand CFU/seed. After germination, the number of seedlings was reduced to 5. In the vegetation experiment with peas, 10 seeds were planted in each vessel. Before plant- ing, they were treated with a suspension of Rhizobium leguminosarum 31Str at a rate of 500 thousand CFU/seed. After germination, the number of seedlings was reduced to 5. Vegetation experiment with wheat involved the use of a suspension of Paenibacillus poly- myxa КВStr at a rate of 400 thousand CFU/seed. Ten seeds were planted in each vessel, and after the germination, the number of seedlings was reduced to 5. Repetition of experiments is three times. Sampling of rhizosphere soil and washed roots (as well as root nodules in the experiment with peas) was carried out according to the ap- propriate methods [40] over time, at Day 15, 30 and 45 after germination. The number of A. bra- silense 410str was determined using the semi- liquid medium Nfb [39] by the limiting dilutions method. Additionally, an acetylene test was used to establish positive (with a “+”) dilutions [41]. Acetylene reduction activity was deter- mined on a Chroom-5 gas chromatograph with a flame ionization detector. The calculation of the number of azospirilla was carried out by McCready tables. To determine the number of R. leguminosarum 31Str, an aliquot of the root nodules of peas (each nodule separately) was destroyed with a sterile glass rod in the sterile test tubes with the addition of 1 mL of sterile tap water, after which the resulting suspension was sown on Petri dishes with pea agar (with the addition of streptomycin sulphate 2.000 μg/mL). The dilution of rhizosphere soil and washed wheat roots to detect P. polymyxa KBStr was sown on MPA with streptomycin sul- fate at a dose of 2,000 μg/mL. The repletion of microbiological tests is 9 times. The significance of differences between variants was evaluated by Student’s t-test at p ≤ 0.05. Test results are presented in the tables using the smallest significant difference, in the figures — as the arithmetic mean and the arith- metic mean error. Statistical processing of experimental data was performed using Microsoft Office Excel 2003–2007. Results and discussion. Field experiments. Determining the de- pendence of potato yield levels on fertilizer in- dicates high efficiency of 40 t/ha of cattle ma- nure (Table 1). Significantly lower crop yields, although with a significant gain in control parameters, were observed with the use of lupine green ma- nure.

This can be explained by the fact that under the conditions of a long-term stationary field experiment, the processes of biological trans- formation of nitrogen compounds were balan- ced. The combination of straw with green ma- nure provided a significant increase in crop yields. Lupine green manure helped to increase productivity also in combination with animal manure. Thus, green manure provided an in- crease in the effective fertility of leached cher- nozem. Potato yields when mineral fertilizers were introduced to the soil, were practically at the level of the “animal manure + green manure” variant. The efficiency of Biohran depended on the characteristics of the crop fertilization. A signif- icant increase in inoculation parameters was re- ported in the variant without fertilizers. The predicted increase in yield was obtained by growing inoculated plants on the background of N80P80K80. Under the exposure to 5 t/ha of straw and Biohran, a tendency to increase crop pro- ductivity only was noted. The effect of the prep- aration on the formation of yields when growing potatoes on a green manure background should be clearly emphasized. At the same time, the ef- ficiency of potato inoculation was higher against the background of green manure with straw. When growing the crop on the back- ground of animal manure, the efficiency of the biological preparation was smoothed down, but the cultivation of inoculated plants under com- bining animal manure with lupine green manure provided a significant increase in crop yield. The first year aftereffect of organic fertiliz- ers generally had a positive effect on the yield of the next crop in the crop rotation — spring barley (Table 2). However, the straw aftereffect showed only a tendency towards the increase yields. A significant increase was reported in straw plus lupine green manure aftereffect. As with potato growing, this combination contrib- uted to higher yields than with each of these fer- tilizers individually. The yield of barley increased by 1.33 t/ha under animal manure aftereffects, but against ISSN 1997-3004 Сільськогосподарська мікробіологія. 2020. Вип. 32. 23 Table 2.

The direct impact of mineral fertilizers on the productivity of the agrocenosis was at the level of 0.87 t/ha. The use of Mikrohumin for pre-sowing in- oculation of seeds contributed to a significant increase in barley yield for all studied agrarian backgrounds, but the lowest rate in the experi- ment was observed in the first year aftereffect of cattle manure. When cultivating peas based on the second year aftereffect of organic fertilizers, a positive effect of all agrarian backgrounds on crop yields was reported. Furthermore, the aftereffect of 5 t/ha of straw provided a significant increase in yield (Table 3). The aftereffect of cattle manure was almost at the level of the aftereffect of lupine green manure, but the effect of the combined applica- tion of these two types of organic fertilizers was much higher than the effect of each of them separately. The highest yields in the experiment were obtained by direct action of N30P30K30. The efficiency of Ryzohumin, used for pre- sowing inoculation of pea seeds, was almost at the same level for all organic agrarian back- grounds. It was slightly higher under the direct action of N30P30K30 (Table 3). Under the third year aftereffects of organic fertilizers, their influence on the formation of winter wheat yield was insignificant and was within the statistical error of the results (Tab- le 4). The only exception was the aftereffect of animal manure and lupine green manure ap- plied together, which provided a yield increase of 0.28 t/ha. The highest parameters of crop yield in the experiment were obtained by direct action of mineral fertilizers at the rate of N60P60K60. The positive effect of the microbial prepara- tion Polimiksobakteryn on the yield of winter wheat was manifested in all variants of the ex- periment, but when growing the crop in the third year aftereffect of organic fertilizers, it was much smaller than under direct action of miner- al fertilizers.

Thus, the positive effect of bio- logical preparations is smoothed out at the year of direct action of cattle manure and is gradually restored over time under the aftereffects of this factor. We attribute this to the fact that a huge number of microorganisms enter the soil along with animal manure [42; 43], which can create a strong competitive environment for the agro- nomically useful microorganism introduced into the agrocenosis. Although animal manure mi- croorganisms are represented by many species of bacteria and micromycetes, including those that are not characteristic of effective interaction with plants, they can provide high competition for the substrate and occupy free ecological niches and create unfavourable conditions for survival in the root spheres of bacterial plants which is the basis of the studied biological preparations. We have previously [37] hypothe- sized non-specific bacterization of the soil with the introduction of animal manure, which may prevent the successful introduction of agronomi- cally beneficial microorganisms in agrocenoses. Another situation is registered upon the cul- tivation of crops on the background of lupine green manure. The biomass of green manure is relatively weakly contaminated with microbiota and, in our opinion, does not interfere with the successful introduction of agronomically valua- ble bacteria. At the same time, green manure contains a significant amount of water-soluble organic substances, proteins and starch [44], which are rapidly mineralized and can addition- ally provide microorganisms with easily digest- ible organic compounds. Also, this organic ferti- lizer has a positive effect on plant nutrition, due to which they increase the root system and the production of root exudates [45], which can stimulate the reproduction of microorganisms. This is confirmed by the improvement of the situation when combining green manure with straw and even animal manure. Straw as a fertilizer has little effect on the efficiency of pre-sowing inoculation, which confirms the well-known thesis that it rather has influence on the potential fertility of the soil ISSN 1997-3004 Сільськогосподарська мікробіологія. 2020.

At the same time, the use of straw can affect the efficiency of biological prepara- tions to some extent through the impact on the processes of biological transformation of nitro- gen compounds. Both positive and negative effects of organ- ic fertilizers fade over time, which is quite logi- cal given the changes in the state of the micro- biota in the soil, and due to the gradual shortage of nutrients. Study of the survival of biological agents of microbial preparations in root spheres of plants. To clarify some assumptions about the influence of organic agrarian backgrounds on the survival of agronomically useful microor- ganisms in the root spheres of plants, studies were conducted under the conditions of vegeta- tion experiments. Studies of the development of A. brasilense 410Str in the root spheres of potato plants have revealed significant differences between the var- iants. The development of the introduced mi- croorganism in the rhizosphere soil is the largest under the mineral agrarian background (Fig. 1). Compared to other variants of the experiment, azospirilla develop more intensively under the action of lupine green manure, as well as when combining green manure with winter wheat straw. The lowest number of the studied bacteria in the rhizosphere soil were observed when growing potatoes against the background of cat- tle manure. The number of azospirilla during the culti- vation of plants on a background of straw has almost no difference from the control parame- ters. We explain this by the fact that in the year of straw application, the processes of its miner- alization are only beginning to develop and do not significantly affect the number of A. bra- silense 410Str. The dependence of A. brasilense 410Str de- velopment from the agrarian background on the roots of potato plants has a much more con- trasting appearance (Fig. 2). Azospirilla develop intensively on the roots under a mineral agrarian background, however the highest parameters of the number of bacteria are noted under the cul- tivation of plants on a green manure back- ground. Whilst they are the highest in the exper- ISSN 1997-3004 Сільськогосподарська мікробіологія. 2020. Вип. 32. 26 W/o fert.: without fertilizer; G.m.: green manure; A.m.: animal manure Fig. 1.

Introduced azospirilla are extremely poorly developed on the roots of plants grown on the background of cattle manure. No signifi- cant difference was observed between the pa- rameters of the number of A. brasilense 410Str upon growing potatoes in the control variant and on the background of straw both in the rhizo- sphere soil, and on the roots of plants. At the same time, when combining straw with lupine green manure, the intensity of development of azospirilla increases significantly. The reported peculiarities of A. brasilense 410Str development in the root spheres of potato plants are largely maintained in the experiment with spring barley, where the first year afteref- fect of organic fertilizers on the survival of azospirilla was studied. The highest parameters of the number of streptomycin-resistant azospi- rilla in the rhizosphere soil of barley plants were observed for growing plants on a mineral back- ground (Fig. 3). Relatively high intensity of A. brasilense 410Str development is observed in the first year aftereffect of lupine green manure, including the combination of this fertilizer with straw. The lowest values of streptomycin-resistant azospirilla were observed upon the aftereffects of cattle manure. The development of A. brasilense 410Str on the roots of barley plants also depended on the agrarian background (Fig. 4). The highest val- ues were reported under the cultivation of plants on the mineral background, as well as under the aftereffects of green manure, including combi- nation with wheat straw. Variants with cattle manure are still unfavourable for the develop- ment of Azospirillum brasilense 410Str. A slight positive effect is observed from the aftereffect of wheat straw.

This can be explained both by a decrease in the effect of organic fertilizers on the efficiency of bacterial introduction over time, and (or) the lack of significant competition between micro- organisms in the formation of nitrogen-fixing symbioses. These studies should be continued using other methods, including serological. In the vegetation experiment with winter wheat upon the third year aftereffect of organic fertilizers, a significant smoothing up of both the negative impact of cattle manure and the positive effect of lupine green manure on the development of P. polymyxa KBStr in the root spheres was registered (Fig. 5 and 6). At the same time, the parameters of variants with green manure still exceed the value of control, which indicates its positive impact on the development of plant-microbial interactions even in the fourth year aftereffect. A slight negative impact on the studied parameter is still observed in the variant with animal manure. Conclusion. The efficiency of microbial preparations in the system of organic farming largely depends on agrarian backgrounds. The use of cattle manure offsets the positive effect of inoculation in the year of direct action of the fertilizer and in the first year aftereffect, due to the low level of survival of the microorganism introduced into the agrocenosis in the root spheres of plants under these conditions. Over time, the negative effect of animal manure on the efficiency of biological preparations de- creases. The use of green manure (narrow- leaved lupine) for fertilization helps to increase the efficiency of pre-sowing inoculation both in the year of direct action of this fertilizer and un- der its aftereffects. To reduce the negative im- pact of litter manure on the efficiency of micro- bial preparations, it is proposed to use lupine green manure together with animal manure. This is confirmed both by the level of crop yield and by studies of the survival of microorgan- isms introduced into agrocenoses in the root 0 15 30 45 60 75 90 105 W/o fert. Straw G.m. A.m.

The use of straw as a fertilizer does not significantly affect the efficiency of microbial preparations upon the first and second year aftereffects. Over time, the influence of straw on the efficiency of inoculants increases. To increase the effect of biological preparations on crop productivity, the combination of straw with green manure deserves attention. REFERENCES 1. Bashan, Y., & Levanony, H. (1990).

П. Сидоренко, В. В. Волкогон, С. Б. Дімова, К. І. Волкогон, Н. В. Луценко, Н. П. Штанько, І. А. Земська Інститут сільськогосподарської мікробіології та агропромислового виробництва НААН, м. Чернігів e-mail: sydorenkochrom@gmail.com Мета. Дослідити вплив різних органічних агрофонів та їх поєднань на ефективність пе- редпосівної інокуляції насіння та розвиток інтродукованих мікроорганізмів у кореневих сфе- рах культурних рослин. Методи. Мікробіологічні, газохроматографічний, вегетаційного та польового дослідів, статистичні. Результати. У тривалому польовому стаціонарному дос- ліді на чорноземі вилуженому встановлено стимулювальну дію та післядію проміжного си- дерату (люпин вузьколистий) на прояв ефективності мікробних препаратів за вирощування картоплі, ячменю ярого, гороху та пшениці озимої в сівозміні. Застосування 5 т/га соломи слабо впливало на ефективність інокуляції, проте поєднання соломи із зеленим добривом за- безпечувало суттєве зростання показників урожайності. Позитивний вплив соломи на ефе- ктивність передпосівної інокуляції проявляється за післядії цього добрива. Внесення 40 т/га підстилкового гною великої рогатої худоби (ВРХ) нівелювало ефективність мікробних пре- паратів у рік прямої дії та першого року післядії добрива. З часом негативний вплив гною на дію біопрепаратів зменшувався. За вирощування сільськогосподарських культур по фону «гній + сидерат» негативна дія гною на вплив інокуляції суттєво знижувалася. За моделю- вання умов вирощування сільськогосподарських культур у вегетаційних дослідах та викори- стання генетично маркованих штамів бактерій — біологічних агентів мікробних препара- тів — встановлено, що в рік внесення органічних добрив на розвиток Azospirillum brasilense 410Str у кореневих сферах рослин позитивно впливає люпиновий сидерат, а використання під- стилкового гною ВРХ — навпаки, призводить до суттєвого зменшення чисельності азоспі- рил. Поєднання зеленого добрива з гноєм ВРХ деякою мірою компенсувало негативний вплив останнього на розвиток інтродукованої бактерії. В умовах першого року післядії органічних добрив в кореневій зоні рослин ячменю ярого ці особливості зберігаються. За вирощування гороху залежність між утворенням кореневих бульбочок Rhizobium leguminosarum 31Str та другого року післядії органічних добрив не простежується. За вирощування пшениці озимої в умовах третього року післядії органічні добрива незначною мірою впливають на розвиток Paenibacillus polymyxa КВStr у кореневих сферах рослин. Водночас у варіантах післядії соломи або сидерату показники дещо перевершують контрольні. Незначний негативний вплив на чисельність бактерії все ще проявляється у варіанті з післядією гною. Висновки. Викорис- тання органічних добрив може суттєво впливати на ефективність передпосівної інокуляції. Дія та післядія підстилкового гною ВРХ негативно впливає на розвиток інтродукованих в агроценоз агрономічно корисних бактерій і значною мірою нівелює позитивний вплив біопре- паратів на урожайність культур.

Study the competitiveness, complementarity and symbiotic activity of a new strain of chickpea nodule bacteria Mesorhizobium ciceri ND-64, study the influence of seed inoculation on the productivity and yield of chickpea varieties of Ukrainian selection under their cultivation in different soil and climatic zones of Ukraine. Methods. Serological, gas chromatography, field experiment and statistical. Results. The use of a new strain of M. ciceri ND-64 for pre-sowing bacterization of chickpea seeds of varieties Skarb, Admiral, Odysei, Budzhak, Triumf and Pamiat upon growing in field experiments in the Steppe zone against the background of the local population of nodule bacteria contributes to a significant increase in nitrogen-fixing nodules by 5 % to 67 %, an increase in the mass of nodules by 10 % to 67 % and nitrogenase activity 26 % to 150 % compared with the positive control (inoculation with the reference strain of M. ciceri H-12). The use of M. ciceri ND- 64 for pre-sowing bacterization of chickpea seeds under cultivation in the Steppe zone of Ukraine also had a positive effect on increasing the yield of chickpea — by 4 % to 18 % compared to the positive control. Inoculation with a new strain of chickpea seeds of varieties Skarb, Triumf and Pamiat contributed to the formation of higher number of nodules (by 57 % to 89 %), increaseed mass of nodules (2.2–2.9 times) and their nitrogenase activity (2–4 times) compared with the positive control upon cultivation in the Polissia zone on the fields where there is no population of chickpea rhizobia. Under these conditions, an increase in structural parameters of yield, the highest gain in chickpea yield, increase in photosynthetic activity and protein content in grain upon inoculation with M. ciceri ND-64 was shown. Obtaining a specific antisera by immunization of rabbits allowed to detect serological relatedness of M. ciceri ND-64, M. ciceri H-101, Mesorhizobium sp. ND-601 and M. ciceri ND-64, isolated from chickpea nodules of Skarb and Pamiat varieties. The competitiveness of M. ciceri ND-64 was determined using the immunological method in the field experiment. It was found that 100 % of nodules have been formed by the representatives of M. ciceri ND-64 in the variant where this serological group was applied for inoculation in the variant with inoculation of the strain M. ciceri ND-64 100 % of the nodules were formed by representatives of this serogroup. Conclusion. M. ciceri ND-64 strain is an effective microsymbiont of chickpea plants, due to its virulence, competitiveness, nitrogen-fixing properties. According to the results of field experiments, it was shown that the new strain, complementary to all studied varieties differing in seed size and shape, type of bush and average height, forms an effective symbiosis for growing chickpea plants both against the active local population of rhizobia and upon the absence of M. cicerі population in the soil. Symbiotic parameters upon seed treatment with suspension of M. ciceri ND-64 exceed these values in the variants with inoculation using the reference strain of M. ciceri H-12 and strains isolated from the nodules of each study variety. Therefore, M. ciceri ND-64 can be used as a bioagent of a microbial preparation for inoculation of chickpea of different varieties in order to form an effective bean-rhizobial symbiosis, increase the productivity of this culture and improve seed quality.

Застосування мікробних препаратів для інокуляції насіннясільськогосподарських культур за їх вирощування по фону прямої дії та післядії проміжноголюпинового сидерату, у т. ч. й за поєднання зеленого добрива з соломою, забезпечує інтенсивний розвиток інтродукованих мікроорганізмів в кореневих сферах рослин і зростанняурожайності.
