As known, seed drills are the most complex agricultural machines in terms of the performed technological process since they include a number of sequentially or concurrent operations. The modern crop farming technologies shall include practices that improve soil fertility through the application of organic and mineral fertilizers. Sustainable crop production is carried out with environmentally friendly and economically competitive farming methods. The object of this paper is to determine the main agrotechnical parameters of universal seed-fertilizer stubble drill SZS-4U. The research methodology has involved determination of the main agrotechnical parameters of the seeder. Based on the research results it was found that the uneven seeding of winter and spring wheat at two speed modes was 2,98% and 3,04%, for spring barley is was 2,70% and 3,00%, mineral fertilizers – 7,57% and 7,69%. With the optimum depth of the openers, the actual depth of seeds placement of spring wheat was 56,5 and 48,9 mm, winter wheat – 44,5 and 43,9 mm, spring barley – 48,0 and 44,3 mm, these data meets a given depth of seeding. After SZS-4U has passed there’s been retained 68,12 – 72,38 percent (%) of stubble on unprepared or minimally prepared grounds, and these values meet agrotechnical requirements which stipulate at least 65 ± 10%. Thus, we can conclude that the universal seed-fertilizer stubble drill SZS-4U meets all agrotechnical requirements and stipulated indicators in terms of sowing winter wheat, spring barley, and spring wheat with simultaneous fertilization.

In 2016-2018, scientific research was carried out on the experimental field of the Ulyanovsk agricultural research Institute on leached heavy loam chernozem to assess the effectiveness and aftereffect of mineral and organic fertilizers in the technology of cultivation of spring wheat varieties, depending on the level of intensification. Weather conditions over the years of research were characterized as quite favorable, but during the period of germination-tillering plants experienced a lack of productive moisture, which affected the overall productivity of the crop and the effectiveness of organic and mineral fertilizers. Spring wheat crops used the aftereffect of straw of the previous crop (winter wheat) and manure, as well as the effect and aftereffect (introduced under winter wheat) of mineral fertilizers. The responsiveness of varieties to mineral and organic was different, which was explained by varietal features and the conditions of water availability of the year. Separate planting of winter wheat straw in the soil did not lead to a significant increase in crop productivity. High availability of soil by mineral nutrients (natural fertility) allowed to get depending on grade from 2.3 to 2.96 t/ha of grain in the control variant (without fertilizers), on the ground the advantage was with the variety Margarita (2,96 t/ha). The largest grain yield was formed by spring wheat of Margarita variety, but this variety showed less responsiveness to mineral and organic fertilizers. On average, the increase in yield, depending on the level of intensification, was 0.3-0.5 t / ha. The use of complex fertilizers for pre-sowing cultivation and the aftereffect of organic fertilizers led to an increase in the content of protein (up to 14.1-15.9 %) and gluten (up to 25.9-30.0 %).

Research on the effectiveness biomodified mineral fertilizers were carried out on the basis of Ulyanovsk SRIA – SamSC RAS branch during the rotation grain fallow five fields crop rotation: pure steam – winter wheat – spring wheat – barley – oats in 2013-2018. The field experiment scheme included options (except control): with the introduction of biologics BisolbiFit (introduction with seeds that were treated before sowing), azofoski N15P15K15, in pure form, modified with biopreparation azofoski in the same dose N15P15K15, half a dose of modified azofoski (N7, 5 P7, 5 K7, 5). The effectiveness of fertilizers and biopreparations in crop cultivation was studied on three backgrounds: natural (control), ammonium nitrate at a dose of 40 kg ai/ha (NH4NO3), and modified ammonium nitrate at a dose of 20 kg DW/ha. It was established that modification of azofoski with Bisolbifit biopreparation can significantly increase the coefficients of use of elements from it by plants. The latter allows to reduce the dose of fertilizer, without reducing the productivity of cultivated crops, twice. Long-term cultivation of crops using only mineral fertilizers and biological products led to a relative decrease in the humus content in the soil and its acidification. For 6 years, the content of humus in the arable layer of leached chernozem decreased by 0.12 %, and the acidity of the soil solution increased by 0.5 pHKCI units. In the conditions of the Volga forest-steppe, when cultivated on chernozems, the highest-yielding winter wheat is (up to 4.00 t / ha or more, in our experiments 3.88-4.80 t / ha). The average yield of spring wheat was 2.68-3.31 t / ha, spring barley 2.67-3.21 t / ha, oats 2.15-2.71 t / ha. The highest productivity of crop rotation was observed against a background with modified ammonium nitrate at a dose of 20 kg ai/ha (½NH4NO3) when applying modified azofoski (N15P15K15). Grain harvest for 2013-2018 in this variant was 13.36 t / ha, exceeding the control variant on this background by 1.31 t / ha.

SUMMARYAn experiment at Rothamsted during 1958–67 measured effects on yield, on K uptake and on soil K of applying all combinations of 38, 75 and 113 kg N and 0, 31 and 62 kg K/ha per cut to grass leys, which were cut and removed. Soil K was depleted most where most N and least K were given. Annual applications of 0, 33 and 66 kg P/ha were also tested; soil P was not depleted. The grass was then ploughed.In 1968, residual effects were measured by spring wheat. In 1969 and in 1970 104 kg/ha of fresh K was applied on half of each plot; potatoes (1969) and spring wheat (1970) valued residual and fresh effects of K.In 1971 potatoes tested 0, 104 and 208 kg/ha of fresh K, cumulatively with the three amounts given to the grass and also extra K (104 kg/ha) on half-plots, cumulatively with that given in 1969 and 1970. In 1972 winter wheat, and in 1974 and 1975 spring barley, measured residues of all treatments previously applied (the site was fallowed in 1973).Finally, in 1976, potatoes tested 0, 156 and 312 kg/ha of fresh K on whole plots, cumulatively with the previous dressings of K, and also 156 kg/ha of extra K on half-plots, again cumulatively. All these test crops were given basal N.Yields and K contents of wheat at ear emergence and yields of wheat grain were largest after grass given 38 kg N and 62 kg K/ha per cut, because here soil K depletion was least. Wheat grain yields benefited consistently from fresh K. K content of the wheat at ear emergence was a good indicator of the need for K, but K content of grain was not, because it was unaltered by K fertilizer. Barley was a poor test crop for K, because yields of grain were little affected by previous treatments.Percentage K in potato leaves (in July in 1969 and 1971, in August in 1976) and yield of tubers were well correlated. Largest yields in 1969, 1971 and 1976 came where the leaves contained 3·43, 3·76 and 2·82% K, respectively, i.e. from soil containing most exchangeable K, plus most fresh K. There was no indication that maximum yields had been obtained, so the largest amounts (kg/ha) of fresh K tested (104 in 1969, 312 in 1971 and 468 in 1976) were insufficient to counteract depletion of soil K by the grass. Because the grass did not deplete soil P, the test crops benefited only little from either residual or fresh P.

Abstract. The goal is to study the influence of the predecessor and fertilizers on the yield and quality of winter wheat grain. Methods. The studies were carried out in a long-term stationary field experiment on a gray forest medium loamy soil. Field experience, observations, accounting and generalization of research results were carried out in accordance with the methodological recommendations of B.A. Dospekhov. Statistical processing of the research results was performed using Microsoft Excel 2007 with a 95 % significance level of the results. Results. As a result of the studies, it was noted that the studied predecessors had an insignificant effect on the development of winter wheat plants in the initial phases of growth. The density of winter wheat plants during the germination period varied within the range of 314–323 psc/m2 without the use of fertilizers and 317–328 psc/m2 against the background of their application. Further growth and development of plants took place in close relationship with the studied factors. At the end of the growing season, the number of productive stems was higher on the plots, where the clover of the first year of use was used as a predecessor, both in the control (without fertilizers) and when applying mineral fertilizers. Accordingly, the yield of winter wheat grain was higher for this predecessor, averaging 35.7 c/ha for 2014–2019. Without fertilization, depending on the predecessor, 25.2–32.8 c/ha were obtained, against the background of fertilization – 34.2–39.6 c/ha of winter wheat grain. On average, over the years of research, winter wheat grain contained 10.7–14.0 % protein. Depending on the year, this indicator varied from 8.8 % to 16.8 %. At the same time, the lowest values for the protein content were obtained for the variants without the use of fertilizers. In general, the content of protein and gluten in winter wheat grain largely depended on the application of mineral fertilizers and to a small extent on the predecessor. The weight of 1000 grains, depending on these factors, changed insignificantly.

Rhizoctonia oryzae (teleomorph = Waitea circinata) causes sheath spot of rice and root rot of wheat and barley. R. oryzae commonly is isolated from barley, wheat, and pea plants in eastern Washington and Idaho. Eight representative isolates were tested for virulence on spring barley (Hordeum vulgare cv. Baronesse), soft white winter wheat (Triticum aestivum cv. Madsen), and hard red spring wheat (cv. Scarlet) planted in natural soil in the greenhouse and maintained at 16°C. All isolates caused significant reduction of emergence in barley, but only seven of the eight isolates and one of the eight isolates reduced emergence of winter wheat and spring wheat, respectively. All isolates caused significant stunting and reduction in the number of seminal roots, root length, and number of root tips on wheat and barley. Some isolates also reduced the frequency of fine secondary roots, resulting in a reduction of the average root diameter. Spring barley was more susceptible to R. oryzae than winter or spring wheat. The main effects of both cultivar and isolate were significant, and there was a significant isolate-cultivar interaction. R. oryzae isolate 80042 was the most virulent on barley, whereas R. oryzae isolate 801387 was the most virulent on wheat. The two isolates from pea were intermediate in virulence on wheat and barley. When screening germ plasm for potential resistance, isolates exhibiting the maximum virulence for each host should be used.

In long-term stationary experiments under different soil-climatic conditions, an influence of mineral and organic fertilization on yield of winter wheat, spring barley and potato tubers was evaluated. Statistically significantly lowest grain yields of winter wheat (4.00 t/ha) and spring barley (2.81 t/ha) were obtained in non-fertilized plots at all experimental sites. In the case of potatoes, the lowest yield of dry matter (5.71 t/ha) was recorded in the control plot, but the result was not statistically significant. The manure-fertilized plot gave the average yield of wheat higher by 30%, of barley by 22%. Application of sewage sludge resulted in wheat yield higher by 41% and barley yield higher by 26% over control. On average, application of sewage sludge and manure increased the yield of potatoes by 30% over control. The highest yield was obtained after application of mineral fertilizers; average yield increased by 59, 50 and 36% in winter wheat, spring barley and potatoes, respectively. No statistically significant differences among the plots with mineral fertilizers were observed. At different sites, the yield of studied crops varied; however, the effect of fertilization on yield increments was similar at all experimental sites except for Lukavec. It is the site with the lowest natural soil fertility, and it showed the highest effect of the applied fertilizers.

The most widely-quoted estimates of straw supplies and usage in England and Wales are those of a working party of the National Farmers Union (1973). They assumed the yield of straw to be 2.8 t/ha, and hence 9.3 Mt from 3.4 M ha of cereals in 1972. (The same yield from 3.7 M ha of cereals in the UK would give 10.4 Mt.) Of the 9.3 Mt, 37% was estimated to be burned in the field or ploughed in, 36% used for bedding, 15% used for feed, and 12% used for other purposes. The figure of 2.4 t/ha (1 t/acre) may well be too low. Short (1974) found straw yields at four Experimental Husbandry Farms over several years to be as follows (t/ha): winter wheat 3.71, spring wheat 4.68, spring barley 2.71, and spring oats 4.54. Wood (1974) surveyed wheat crops in Oxfordshire in 1973 and found yields of 3.7 t/ha. The total quantity of straw available is therefore likely to be considerably in excess of 9.3 Mt and could if necessary be increased further by cutting at a lower level. The accuracy of the National Farmers Union estimate of 0.15 × 10.4 = 1.6 Mt used for animal feeding is also questionable, but this amount would — if it contained 6.5 MJ metabolizable energy (ME)/kg dry matter (DM) — be sufficient to provide only about 7% of the maintenance requirements of all cattle in Britain. On a larger scale, Balch (1977) has calculated that if all the straw grown in Europe were improved by chemical treatment it could provide 80 to 90% of the maintenance requirements of Europe's ruminant livestock. World estimates for the production of straw and other fibrous wastes are given by Owen (1976).

Abstract The research was carried out on a permanent fertilization field in the area of the Rzeszow Foothills Region, with Haplic Luvisols formed from loess. The following plants were cultivated in a 4-year cropping system: pasture sunflower, winter wheat, potatoes and spring barley. Various mineral fertilizers NPK + Mg constans and various mineral fertilization NPK + Mg Ca constans were applied in the experiment. Liming was applied in the form of CaO (at the dose of 2.86 t Ca × ha.1). The experiment included 14 fertilizer objects, in 4 replications according to the method of random sub-blocks. Analysis of variance (ANOVA) was applied in statistic processing for a double classification: liming (A) and mineral fertilization (B) . independently of liming. As a result of the testing, it was found that liming raised the content of Cr in Ap and Bt horizons. Mineral fertilization raised the content of Co and Cr in Ap and Bt horizons and Cd and Pb in Bt horizon. The combined effect of liming and mineral fertilization decreased the content of Ni and Co in Ap horizon and Cd in Bt horizon and raised the content of Cr in Ap and Bt horizons and Pb in Bt horizon.

Objective. To determine the features of potential N2O emission from the rhizospheric soil of plants under different crop fertilization systems. Methods. Field experiment, gas chromatographic methods. Results. In the field stationary experiment on leached chornozem during crop rotation in potato, spring barley, peas and winter wheat, it was shown that potential N2O losses from the rhizo-spheric soil of plants depend on fertilizing systems and microbial preparations. The losses of nitro-gen gaseous compounds are proportional to the standards of the applied mineral nitrogen fertiliz-ers. High N2O emission rates are observed in the first year of cattle manure application and during its after-effect. Emission of nitrous oxide also increases with organo-mineral fertilization. The use of microbial preparations in crop cultivation technologies: Biogran for potatoes, Mikrogumin for spring barley, Rhizogumin for peas, Polimiksobakteryn for winter wheat under the application of mineral fertilizers, contributes to a significant limitation of nitrogen gas losses. This is due to the increase of the absorption coefficients of the active substance from the fertilizers by bacterization-initiated plants and, consequently, the decrease in mineral nitrogen compounds in the rhizospheric soil. When growing potatoes by an organic agrarian background (40 t/ha of manure), the signifi-cant effect of Biogran on the course of the biological denitrification process has not been estab-lished, which can be explained by the formation of an intense pool of microorganisms under the use of manure, and the levelling of pre-sowing bacterization due to this effect. Conclusion. The use of microbial preparations for inoculation of agricultural seeds helps to reduce the emission of nitrous oxide from rhizospheric soil of plants under their cultivation by mineral agrarian backgrounds, which is important both economically and environmentally.
