ЦЕОЛИТЫ И УДОБРЕНИЯ НА ЕГО ОСНОВЕ В ТЕХНОЛОГИИ ВОЗДЕЛЫВАНИЯ СОИ В ЛЕСОСТЕПИ ПОВОЛЖЬЯ

Experimental field studies were carried out on the experimental field of Ulyanovsk State Agrarian University in 2018-2020. The experiment scheme in 2019 (laid in 2018) consisted of 4 variants: 1. Control (without fertilizers); 2. Zeolite in pure form, 500 kg / ha; 3. Organic mineral fertilizer, obtained by enriching zeolites with amino acids, 500 kg / ha; 4. Zeolite 500 kg / ha + N40 (carbamide at the dose of 40 kg of nitrogen per 1 ha). In 2020, the experiment was supplemented with four variants in order to identify more appropriate doses of fertilization (zeolite enriched with amino acids, 250 kg / ha; zeolite enriched with amino acids, 500 kg / ha; zeolite enriched with carbamide, 250 kg / ha; zeolite enriched with urea , 500 kg / ha). The experiments were carried out in 3-fold repetition with a randomized placement of plots. The effect of zeolite from Yushansk deposit of Ulyanovsk region and fertilizers based on it enriched with amino acids and urea were studied in the experiment, as well as their effect on general biological activity of leached black soil, on its agrochemical parameters, photosynthetic activity of soybean crops, yield and seed quality. A significant influence of experimental fertilizers on biological activity of the soil, improvement of nutrient regime, as well as the ability of zeolite to neutralize soil acidity was found. Improvement of the soil environment in case of application of zeolite enriched with amino acids and urea as a fertilizer contributed to an increase of soybean yields by 6-14% and by 12-31% to improvement of the product quality. With an increase of the dose of fertilizers, the yield of soybean seeds increased, but not proportionally.

Agronomic and physiological characteristics of soybean cultivars and their seeds according to plant population

Soybean (Glycine max) yield can be influenced by the choice of genetic material along with the use of an adequate plant population and selection of high-quality seeds. This study aimed to evaluate agronomic and physiological characteristics of soybean cultivars and their seeds, according to different plant populations. For this purpose, an experiment was conducted during the 2017/2018 harvest, under field conditions, in a randomized block design in a 3 x 4 factorial arrangement with four replicates. The treatments consisted of three soybean cultivars, TMG2181 IPRO, M 7739 IPRO, and BMX Power IPRO, at four population densities: 180,000; 220,000; 280,000 and 320,000 plants ha-1. The agronomic characteristics of the plants (plant height, stem diameter, number of branches, number of pods per plant, number of seeds per plant, number of seeds per pod, weight of a 100 seeds and seed yield) and physiological quality (germination, first count of germination, seedling length, dry mass of the shoot and root and accelerated aging test) of these seeds were evaluated. The experiment showed that the agronomic characteristics of soybean cultivars and their seeds varied according to the genotypes, and that these phenotypic expressions can be altered according to the plant population. The indeterminate cultivar BMX Power IPRO obtained higher seed yield compared to the semi-determinate and determinate cultivars M 7739 IPRO and TMG2181 IPRO, mainly due to their field conformation and size. The indeterminate cultivar BMX Power IPRO showed higher average germination and seed hardiness and produced normal seedlings with good initial growth rate and dry weight. The yield and quality of soybean seeds were not affected by plant population.

Эффективность листовой подкормки удобрениями с микроэлементами в технологии возделывания сои

The results of testing micronutrientcontained fertilizers developed by Spetsagrokhim LLC and BioEra-Penza LLC in the industrial agrotechnology of soybean cultivation are presented. Based on the results of phenological observations during the entire growing season, the effect of the studied preparations on the growth and development of soybean plants has been assessed. The conditions for the application of micronutrient-contained fertilizers are given according to the recommendations of the developers and taking into account the conducted soil analysis for each option studied. A comparative assessment of the number of formed nodules on soybean roots in the studied options is presented and the influence of the selected options on the formation of yield and quality of soybean seeds is analyzed.

High Phosphorus Acquisition and Allocation Strategy Is Associated with Soybean Seed Yield under Water- and P-Limited Conditions

Both water stress and P deficit limit soybean seed yield, but the effects of water regimes and P application rates, their interaction on P status, acquisition, and partitioning, and their roles in yield performance have not been well-studied. Two soybean genotypes (Huangsedadou (HD) and Zhonghuang 30 (ZH)) with contrasting seed yield and root dry weight (DW) were used to investigate the P status, P acquisition, P partitioning, and yield formation under two water regimes (well-watered (WW) and cyclic water stress (WS)) and three P rates (0 (P0), 60 (P60), and 120 (P120) mg P kg−1 dry soil). The results show that increased P and water supply increased the seed yield, shoot and root DW and P concentrations and accumulations in different organs. Cultivar ZH had a significantly higher seed yield than HD at P60 and P120 under WS and at P0 under WW, but a lower seed yield at P60 and P120 under WW. Cultivar ZH had a significantly higher P harvest index and P acquisition efficiency, but a significantly lower shoot and root DW than HD. The interaction between water treatments and P rates had significant effects on leaf and stem P concentration. Cultivar ZH had significantly lower P partitioning to leaves and stems but significantly higher P partitioning to seeds than HD. The seed yield was positively correlated with leaf and seed P accumulations and P acquisition efficiency under WS. We conclude that (1) adequate water supply improved the P mobilization from leaves and stems at maturity, which may have improved the seed yield; and (2) the high P acquisition efficiency is coordination to high P partition to seeds to produce a high seed yield under water- and P-limited conditions.

Impact of K-Humate and Yeast Extract Combined with Np Fertilization on Soybean Seed Yield, Quality and Protection against some Pests

Two field experiments were conducted at a special farm, in El Mansoura, Dakahlia Governorate, Egypt, during the two growing summer seasons of 2018 and 2019 to find out the influence of soil drench by potassium Humate (KH) and yeast extract (YE) as foliar application alone or combined (KH+YE) under different rates of N and P fertilization on plant growth, yield, quality and protection against some pests of soybean plants (Glycine max L.), c.v. Giza 111. The treatments of NP fertilization rates were arranged in the main plots and the HK and YE were arranged in sub-plots in a split-plot design with three replicates. Results indicated that the application of soil drench KH and YE spraying and (KH+YE) had a positive effect on growth parameters, photosynthetic pigments, seed yield and yield components of the soybean plants. The duel application (KH+EY) showed a significant augmentation in all studied parameters compared to the control under 50, 75 .and 100% of the recommended mineral fertilization does (RFD. The whitefly Bemisia tabaci Genn. represented the most pest attacking soybeans with a ratio around 56 % followed by Aphis cracivora Kock (30%), While Tetranychus urticae Koch ranged (8-10%). respectively .But mealybug Phenococcus solani Ferrisia in % occurrences a ratio around (3-6%) during 2018 and 2019 seasons. In treatment were spray (combined of KH+YE ) decreased population of B. tabaci Genn. (9.75 nymphs /10 leaves). Therefore, this investigation revealed that the synergistic effect of HK (5 ml l-1) and YE (4 g l-1 ) in combination treatment with 75% NP is important for improving plant quality and this decreased insect infestation and the environmental pollution caused by repeated application of agricultural chemicals as mineral fertilizers and pesticides.

Characterization of the Common Genetic Basis Underlying Seed Hilum Size, Yield, and Quality Traits in Soybean.

Developing high yielding cultivars with outstanding quality traits are perpetual objectives throughout crop breeding operations. Confoundingly, both of these breeding objectives typically involve working with complex quantitative traits that can be affected by genetic and environmental factors. Establishing correlations of these complex traits with more easily identifiable and highly heritable traits can simplify breeding processes. In this study, two parental soybean genotypes contrasting in seed hilum size, yield, and seed quality, as well as 175 F9 recombinant inbred lines (RILs) derived from these parents, were grown in 3 years. The h2b of four hilum size, two quality and two yield traits, ranged from 0.72 to 0.87. The four observed hilum size traits exhibited significant correlation (P < 0.05) with most of seed yield and quality traits, as indicated by correlation coefficients varying from -0.35 to 0.42, which suggests that hilum size could be considered as a proxy trait for soybean yield and quality. Interestingly, among 53 significant quantitative trait loci (QTLs) with logarithm of odds (LOD) values ranging from 2.51 to 6.69 and accounting for 6.40–16.10% of genetic variation, three loci encoding hilum size, qSH6.2, qSH8, and qSH10, colocated with QTLs for seed yield and quality traits, demonstrating that genes impacting seed hilum size colocalize in part with genes acting on soybean yield and quality. As a result of the breeding efforts and field observations described in this work, it is reasonable to conclude that optimizing hilum size through selection focused on a few QTLs may be useful for breeding new high yielding soybean varieties with favorable quality characteristics.

ПОВЫШЕНИЕ УРОЖАЙНОСТИ НОВЫХ СОРТОВ СОИ ПУТЕМ ПРИМЕНЕНИЯ КОРРЕКТИРУЮЩИХ ПОДКОРМОК

Abstract. The article presents the results of field experiments to study the effect of foliar dressing on the yield of soybean seeds. The studies were carried out at the FSC ZBK in 2018-2020. In a field experiment on a dark gray forest heavy loamy soil, we studied the reaction of two soybean varieties (Leader-1 and Mezenka) to treatment with the highly effective inoculant Rizoform and foliar application with Ultramag combi microfertilizer and the amino acid biostimulator Biostim oilseed. The experimental design included the following options: control (without inoculation and treatment), seed dressing with Scarlet fungicide, basic treatment (Scarlet and Rizoform inoculant), basic treatment in combination with one and two foliar dressings with the studied preparations. The experiment was repeated four times. Experimental plots area – 10 m2. Sowing was carried out with a SKS-6-10 seeder in a wide-row method (row spacing - 45 cm) in the second decade of May. Seeding rate - 600 thousand viable seeds/ha. According to the results of the experiment, a positive effect of the tested preparations on the formation of the yield of soybean seeds was established. The most effective in terms of the factor of treatments was the option with the use of two foliar dressings with Ultramag combi and Biostim oleaginous at a dose of 0.5 l/ha. The increase in yield on average for the experience was 9.4% in relation to the control. According to the cultivar factor, the Leader 1 cultivar showed a higher yield - 2.87 t/ha versus 2.67 t/ha of the Mezenka cultivar. The responsiveness of the Mezenka variety to carrying out corrective dressing was higher than that of the Leader 1 variety (11.5 and 6.4%, respectively). The profitability of soybean cultivation was 83 - 106%. The economic effect when carrying out two leaf treatments amounted to 2,490 rubles for the Leader 1 variety and 4900 rubles for the Mezenka variety

Study of Production and Distribution of Soybean Seeds In Central Java

The study on the production and distribution of soybean seeds was carried out in January-September 2020. The location of soybean seed production was 33 ha across Central Java Province, Grobogan, Kendal, and Brebes districts. The seeds produced are SS1 class consisting of Grobogan (22 ha), Anjasmoro (10 ha), and Dega 1 (1 ha). Seed production was carried out by cooperating with soybean seed partners. The data collected includes data on prospective soybean seed production, yield, and distribution of soybean seeds. Existing data were analyzed descriptively. The study results showed that the Grobogan seed's productivity was 2,150 kg/ha on average, while the Anjasmoro was 2,030 kg/ha, and Dega 1 was 2,120 kg/ha. Overall yields of soybean seeds from 33 ha were 73,803 kg. The percentage yield of Grobogan was 79.072%, Anjasmoro 80.20%, and Dega 1 was 66.67%. The seeds were distributed to seed producers in the Central Java Province recommended by the Central Java Seed Monitoring and Certification Agency and the Central Java Seed Producers and Traders Association.

Technical Parameters of Spraying with a Biostimulant as a Determinant of Biometrical Properties and Yield of Soybean Seeds

Abstract Spraying with various types of agrochemical substances, including biostimulants, is one of the basic agricultural treatments affecting the yield size and quality. The selected type of spraying nozzles can influence biological effectiveness of the applied substances. A 2-year field study showed which of the investigated nozzles increase the effectiveness of foliar application of a free amino acid biostimulant. The type of nozzle used for the application of biostimulants was reported to significantly influence the biometric properties and yield of soybean cultivation. It was observed that spraying nozzles, which generate finer droplets positively influence positively the biometric properties of plants and seed yield of seed than injector nozzles, which produce coarser droplets. A significant reduction of the thousand seeds mass after applying the biostimulant with standard flat fan nozzles is an exception. A 25.61% increase in soybean yield was reported after applying the biostimulant with standard flat fan nozzles and a 11.35% increase – with injector nozzles..

Impact of microbial consortia on microbial population and available nutrients in soil under soybean crop

The present investigation was conducted to see the effect of microbial consortia on microbial population, available nutrients in soil and yield of soybean grown during 2018-19 under an ongoing All India Network Project on Soil Biodiversity and Biofertilizers at the Research Farm of Department of Soil Science and Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India. Coinoculation in the form of a consortium with Pseudomonas fluorescens (PGPR) Actinomycetes (Actino) and Arthrobacter (Arthro) was found beneficial in enhancing yield of soybean. Application of recommended dose of fertilizers (RDF) along with microbial consortium (PGPR+Actino+Arthro) recorded significantly higher amounts of available nitrogen (N), phosphorus (P) and potassium (K) which resulted in 43, 30 and 37 per cent, respectively over that of fertilized uninoculated control. Similarly, plots receiving RDF+PGPR+Actino+Arthro recorded significantly higher populations of Actinomycetes, Arthrobacter and PGPR at 25, 45 and 65 days after sowing which were 1.71, 1.42 and 1.52 log fold; 1.32, 1.28 and 1.31 log fold; and 1.56, 1.35 and 1.44 log fold, respectively over that of fertilized uninoculated control. In almost all cases, the treatment combinations of RDF+PGPR+Arthro, RDF+PGPR+Actino and RDF+Arthro+Actino exhibited similar performances. Seed and stover yields of soybean increased by 44 and 61 per cent, respectively over that of fertilized uninoculated control. It may be concluded that application of microbial consortia may be followed for enhancing soybean yield, available soil nutrients and microbial populations by direct as well as indirect beneficial effect.

УРОЖАЙНІСТЬ І ЯКІСТЬ НАСІННЯ СОЇ ЗА РІЗНОГО УДОБРЕННЯ НА ЧОРНОЗЕМІ ОПІДЗОЛЕНОМУ

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.

Isoflavones, anthocyanins, phenolic content, and antioxidant activities of black soybeans (Glycine max (L.) Merrill) as affected by seed weight

Seed weight is regulated by several genes which in turn could affect the metabolite contents, yield, and quality of soybean seeds. Due to these, seed weight is receiving much attention in soybean breeding. In this study, seeds of 24 black soybean varieties and a reference genotype were grown in Korea, and grouped as small (< 13 g), medium (13–24 g), and large (> 24 g) seeds based on their seed weight. The contents of six anthocyanins, twelve isoflavones, and total phenolic, and the antioxidant activities were determined, and the association of each with seed weight was analyzed. The total anthocyanin (TAC) and total isoflavone (TIC) contents were in the ranges of 189.461–2633.454 mg/100 g and 2.110–5.777 mg/g, respectively and were significantly different among the black soybean varieties. By comparison, the average TAC and TIC were the highest in large seeds than in small and medium seeds while the total phenolic content (TPC) was in the order of small seeds > large seeds > medium seeds. Besides, large seeds showed the maximum 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging activity, whereas small seeds showed the maximum ferric reducing antioxidant power (FRAP) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS) scavenging activities. FRAP activity was positively associated with TIC and TAC, the former association being significant. On the other hand, ABTS and DPPH activities were positively correlated to TPC, the later association being significant. Overall, our findings demonstrated the influence of seed weight on anthocyanin, isoflavone, and phenolic contents and antioxidant activities in black soybeans. Besides, the dominant anthocyanins and isoflavones were the principal contributors to the variations observed in the black soybean varieties, and hence, these components could be selectively targeted to discriminate a large population of black soybean genetic resources.

Effects of rhizobia and arbuscular mycorrhizal fungi on yield, size distribution and fatty acid of soybean seeds grown under drought stress

Soybean (Glycine max L.) is among the most economically important legumes that provide more than 1/4 of food (for man) and animal feed. However, its yield is comparatively low, most especially under drought stress. The aim of this study therefore was to assess the ability of Rhizobium spp. and mycorrhizal fungi to enhance the yield, seed size and fatty acid content of soybean grown under semi-arid environment. Rhizobium sp. strain R1 was found to possess nitrogen-fixing gene coniferyl aldehyde dehydrogenase function while Rhizobium cellulosilyticum strain R3 was found to have nitrogen-fixing genes cysteine desulfurase SufS and cysteine desulfurase IscS activity. Soybean (Glycine max L) seeds inoculated with Rhizobium spp. and mycorrhizal fungi were cultivated in soil exposed to drought stress. Rhizobium spp. inoculation and mycorrhization alleviate drought stress and increase yield, size and fat content of soybean seeds. This increase in the aboveground parameters was accompanied with an increase in belowground mycorrhizal spore number, percentage root mycorrhization and aboveground shoot relative water content (RWC) in the dually inoculated (R1 + R3MY) soybean plants. In particular, the dually inoculated (R1 + R3MY) soybean plants revealed 34.3 g fresh weight, 15.1 g dry weight and soybean plants singly inoculated with Rhizobium sp. strain R1 (R1) produced more large seeds with 12.03 g dry weight. The non-inoculated (control) seeds contained a higher percentage of moisture content compared to the microbially amended seeds while seeds co-inoculated with Rhizobium cellulosilyticum strain R3 and mycorrhizal consortium revealed the highest percent (8.4 %) of fat. Several fatty acids that are of significant health benefits to humans were observed in the soybean seeds. In order to gain insights into the bacterial communities of rhizospheric soil collected at different stages of soybean growth, class-based Heat-map analysis was performed on the Miseq sequenced data. The core bacteria that were found in the rhizospheric soil were Verrumicrobia, Proteobacteria, Gemmatimonadetes, Firmicutes, Cyanobacteria, Chloroflexi, Bacteroidetes, Actinobacteria, Acidobacteria, Planctomycetes, Deinococcus thermus and Nitrospira suggesting that the rhizobia and fungi used in this study can also improve soil microbial diversity.

PECULIARITIES OF FORMING SOYBEAN PRODUCTIVITY OF OMEGA VINNYTSIA TYPE DEPENDING IN THE TERMS OF SOWING, SEED SOWING STANDARDS IN THE CONDITIONS OF FOREST-STEPPE OF THE RIGHT-BANK

The article presents the data of the field research on the influence of sowing terms with the temperature regime of soil and sowing rates of soybean seeds of Omega Vinnytsia type in the conditions of the Forest Steppe of the Right Bank. It has been determined that sowing terms with the temperature regime of soil at a depth of 10 cm from 6,8,10 and 12 ° C have different effects on growth processes and formation of generative organs on the plant. Optimal sowing periods were the most favourable for intensive growth and development of soybean plants were temperature conditions within 8 and 10 ° C. Sowing at a soil temperature of 10 cm at a depth of 6 ° C reduced the stem height at all seed rates. The height of the lower bean attachment was reduced, as well as the number of beans on the plant and seeds in the bean, while the safety of plants during harvesting was also reduced. Intensive initial growth of soybean crops at sowing at 12° C resulted in increased attachment of lower beans to the stem, but the number of beans per plant and the number of seeds in a bean decreased significantly. The research of the efficiency of sowing soybean types Omega Vinnytsia 600, 700, 800 and 900 thousand germinated seeds per 1 hectare shows at a rate of 600 thousand pieces, stem height, because of their branching, was lower than at the sowing of 700 and 800 thousand n / ha. Also, the height of the lower beans, the number of beans per plant and the number of seeds in the bean were reduced. The highest biometric indicators and the number of generative organs on the plant were observed during sowing with the sowing rate of 700 and 800 thousand n/ha. The increase of soybean seed rate up to 900 thousand n / ha deteriorated biometric indicators of plants and the formation of generative organs. The survival of plants increased at sowing in 6 ° C of soil temperature and with an increase in sowing rate above 600 thousand n / ha. The weight of one thousand seeds changes to a lesser extent depending on the timing of sowing and seed rate and its high indicators were noted at sowing in 8 and 10 ° C and seed rate 700 and 800 thousand n / ha. Increase of soybean seed rate up to 900 thousand n.p. / ha reduces the weight of 1000 seeds against other seed rates for 8-10 years. Years of research were favorable for growing soybeans and obtaining high levels of seed yields. The highest yield of soybean seeds of Omega Vinnytsia variety was obtained at the sowing rate of 10 ° C and it was at the rate of 600 thousand soybean seeds / ha - 36.0 centners / ha; 700 thousand soybean seeds - 44.7 centners / ha; 800 thousand soybean seeds / ha - 40.0 centners / ha and 900 thousand soybean seeds / ha - 38.2 centners / ha. The approximate yield of seeds was obtained at sowing at 8 ° C according to all norms of sowing of seeds in the same regularity as at sowing at 10 ° C. Increase of sowing rate up to 900 thousand n/ha leads to increase of seed yield but also to overspending of seeds and considerable decrease of individual productivity of plants. At the same time, sowing at soil temperature of 6 ° C was more effective than sowing at 12 ° C. and yield was at a rate of 600 thousand seeds. At the same time, sowing at soil temperature of 6 ° C was more efficient than sowing at 12 ° C, and the yield was at the rate of 600 thousand seeds - 27.4 centners / ha, 700 thousand seeds / ha - 33.8 centners / ha; 800 thousand seeds / ha - 29.7 centners / ha and 900 thousand seeds / ha - 30.6 centners / ha. And when sowing at 12 ° C, respectively, 26.4, 31.5, 29.1, 29.2 centners / ha. Key words: sowing dates, sowing rates, plant height, lower bean attachment height, number of beans per plant, number of seeds, seed weight, yield.

Economic and biological and selection value of early ripening soybean varieties in the forest-steppe zone of the Trans-Urals

Soybean is a universal food and feed crop. Soybean protein is close to animal protein in its amino acid composition. Soybean is an excellent precursor for many crops. After soybean, suffi cient nitrogen remains in the soil, which reduces the need for pre-sowing mineral fertilizer for the crop. The purpose of the researches is to determine the economic, biological and selection value of early ripening soybean varieties in the forest-steppe zone of the Trans-Urals. In the forest-steppe zone of the Trans-Ural region, collection samples of soybean were tested for economic, biological and selection characteristics. A comprehensive assessment of precocious soybean varieties on economic and valuable characteristics and yield for environmental plasticity and stability, as well as the correlation between yield and quality indicators of soybean seeds and elements of its structure has been established. Soybean varieties that are adaptive to local natural and climatic conditions have been identifi ed such as: Kasatka, Chera 1, Krasnoobskaya, SibNIIK-315 as sources of valuable traits for further use in breeding and agricultural production. These same soybean varieties were the most cost-eff ective, where the level of profi tability was from 265,0 to 306,3 %. Due to the high yield (from 2,18 to 2,43 t/ha), these varieties provided the highest collection of protein and fat (from 0,87 to 0,95 t/ha), and due to the high protein content in the grain, they provided the lowest prime-cost of this valuable product in soybean (from 5710 to 6360 Rub/t). Early ripening soybean varieties have the highest fat collection per 1 ha (0,40–0,43 t) and the lowest prime-cost (32 250–34 670 Rub/t). Other varieties showed lower yields and as a result were less cost-eff ective. Soybean cultivation in the Tyumen region is economically profi table with the seeds yield of 0,9 t/ha.

Evaluation of nutrient expert - a decision support tool through SSNM in soybean

A field experiment was carried out during kharif seasons of 2017-18 and 2018-19 in AICRP on Soybean at Regional Research and Technology Transfer Station of OUAT, Bhawanipatna, Kalahandi, Odisha to evaluate the effectiveness ofsite specific nutrient management(SSNM)in soybean usingNutrient Expert, a decision support tool. Seven treatments comprising of T1: SSNM(NE) (25:23:19 kg N:P2O5 :K2O/ha), T2: T1-N omission (0:23:19 kg N:P2O5:K2O/ha), T3: T1-P omission (25:0:19 kg N:P2O5:K2O/ha), T4: T1-K omission (25:23:0 kg N:P2O5:K2O/ha), T5: RDF (25:100:50:50kg N:P2O5 :K2O:S /ha), T6: Farmers practice (20:20:20 kg N:P2O5 :K2O/ha) and T7: Absolute control (No fertilizer) were tried in randomized block design (RBD) with three replications. Recommended dose of fertilizer (25:100:50:50 kg N:P2O5 :K2O:S/ha) recorded maximum seed yield ofsoybean (1465 kg/ha) which was at par with application of fertilizer based on site specific nutrient management [SSNM (NE) 25:23:19 kg N:P2O5:K2O/ha] with seed yield of 1352 kg/ha. Yield data from the omission plot treatments suggested that N is the most important major nutrient for enhancing the seed yield of soybean followed by P and K. There was 28.1% reduction in seed yield when N was omitted from SSNM (NE). Omission of nitrogen, phosphorus and potassiumapplication from SSNM (NE) recorded 33.7, 25.1 and 21.7% reduction in seed yield, respectively, as compared to application ofNPKS (RDF). Application ofRDF earned higher gross return to an extent of 8% and 28% over SSNM (NE) and Farmers Practice, respectively, whereas, net return (`13271/ha) and return/rupee invested (1.49) were higher in SSNM (NE).

Influence of bio-preparations and their multiplicity of application on stability of soybean yield in Amur region

The article presents data on the influence of Borogum Mo and Phytosporin-M biopreparations on the yield and composition of oil soybean admixture in different meteorological conditions of Amur region. The experiment included options: Factor A (preparations) - 1. Without preparation (water); 2. Borogum Mo; 3. Phytosporin-M; 4. Borogum Mo + Phytosporin-M; Factor B (number of treatments) - 1. Without treatment. 2. One time. 3. Two times. 1. Factor B (number of treatments) - 1. The conducted researches have shown that the greatest yield of soybean sowing is provided on the average for two years at spraying of plants once in the end of June with Borogum-Mo and a mixture of Borogum-Mo + Phytosporin-M preparations - 2.87 t/ha. When Borogum-Mo is treated, the number of frost seeds decreases, and when treated with Phytosporin-M, the number of affected diseases decreases in comparison with control plots. According to the basic norm of oilseed admixture all used preparations provided the yield of pure soybean seeds.

Yield and quality of soybean seeds inoculated with Bacillus subtilis strains

ABSTRACT The use of growth-promoting bacteria can increase the yield and quality of seeds of several annual crops, such as soybean. Based on that, the present study aimed to evaluate the effects of the inoculation of Bacillus subtilis strains on seed treatment, evaluating the yield and quality of seeds of two soybean cultivars. The experiment was conducted in a conventional system, in an Oxisol of clayey texture, in a crop under sprinkler irrigation. The experimental design was randomized blocks, arranged in split plots with four repetitions. Treatments were composed, in the plots, of two soybean cultivars: M7110 IPRO and Brasmax Desafio RR. Within the levels of subplots, the treatments consisted of inoculation and doses of inoculant: Bacillus subtilis Pant001 strain at doses of 0, 2, 3, 4 and 5 mL kg-1, and QST713 strain at the recommended dose of 2 mL kg-1. Inoculation with the strains Pant001 and QST713 increased the yield of both soybean cultivars tested, besides improving seed quality due to the increase in the concentration of total storage proteins, seedling emergence percentage and seed vigor by the accelerated aging test.
