Winter wheat (Triticum aestivum L.) is a valuable grain crop. The purpose of the current study was to assess the effect of the direct sowing system (no-till, technology without tillage), in comparison with the one recommended for the zone of the Central Steppe of the Crimea, on the agrophysical characteristics of the soil, weed infestation of the plots and winter wheat productivity. The trial was laid in 2015, the study began to be carried out in 2017. In the trials there was studied the winter wheat variety ‘Asket'. The soil of the experimental plot was southern blackearth (chernozem) with 2.0-2.1% of humus, with 2.0-2.7 mg of labile phosphorus per 100 g of soil and 25-30 mg of exchangeable potassium per 100 g of soil. The total area of the plot was 300 m2, the accounting area was 50 m2 with threefold repetition. The average annual air temperature was 10.4 °С, the average annual precipitation was 428 mm. Mathematical processing was carried out according to the Dospekhov's method. The direct sowing in 2017-2019 contributed to the accumulation of available moisture in the soil when growing winter wheat. During the autumn-winter period, there were accumulated 46 mm, which was two times more than in the control variant. The direct sowing did not affect the weed species' composition. Their number in the variants with no-tillage increased by 6.1 pcs/m2. The soil density when sowing in the 0-30 cm layer was at the same level in terms of technologies. During the renewal of the spring vegetation there was soil softening and, on average, over the layers, this parameter was at the level of optimal values. The number of agronomically valuable aggregates was on 2.5% higher with direct sowing than in the control variant. The structural coefficient in the control variant was 2.7, and with no-till it was 3.2. The productivity in the control variant was 3.86 t/ha, and in the direct sowing it was 3.30 t/ha, which was on 0.56 t/ha (14.5%) more in the control variant than in the studied variant.

In recent years, there has been an increasing interest around agricultural science and practice in conservation tillage systems that are compatible with sustainable agriculture. The aim of this study was to assess the qualitative and quantitative changes in weed flora and soil seed bank under reduced tillage and no-till (direct sowing) in comparison with traditional ploughing. In the crop rotation: pea/rape—winter wheat—winter wheat the number and dry weight of weeds increased with the simplification of tillage. The seed bank was the largest under direct sowing and about three times smaller in traditional ploughing. Under direct sowing, most weed seeds were accumulated in the top soil layer 0–5 cm, while in the ploughing system most weed seeds occurred in deeper layers: 5–10 and 10–20 cm. In the reduced and no-till systems, a greater percentage of perennial and invasive species, such as Conyza canadensis L., was observed. The results show that it is possible to maintain weed infestation in the no-till system at a level that does not significantly affect winter wheat yield and does not pose a threat of perennial and invasive weeds when effective herbicide protection is applied.

The current paper has presented the results of three years’ study (2012–2014) of the application of various terms and methods of nitrogen additional fertilizing for the winter bread wheat variety “Stanichnaya”. There has been studied efficiency of various terms and methods of nitrogen additional fertilizing with various forecrops. There has been identified an effect of these additional fertilizing on winter bread wheat productivity according to the forecrops. In the control variant, the productivity of the variety according to the forecrop depended greatly on the forecrops: 5.52 t/ha (weedfree fallow), 5.26 t/ha (peas), 4.29 t/ha (maize for grains) and 3.57 t/ha (winter wheat). There has been identified large productivity in the autumn ammonium nitrate fertilizing by the scattering method (in all variants of the forecrops), the productivity raised on 0.38–0.73 t/ha. The study has shown that the economic effect of the ammonium nitrate fertilizing in the autumn was also at maximum profitability, 76–154%, and the conditional net income was 10 675–22 955 rubles/ha. The efficiency of ammonium nitrate fertilizing by the scattering method in the spring on thawed/frozen soil was lower, the productivity increase ranged from 0.21 t/ha sown after peas to 0.65 t/ha sown after maize. Root additional fertilizing with a seeder gave a positive effect only when the variety was sown after for winter wheat and maize, in that case the productivity increase was 0.52 t/ha and 0.46 t/ha, respectively. The conditional net income in these variants exceeded the control variant on 1574–2123 rubles/ha. Carbamide (urea) additional fertilizing was only effective for the variety sown after maize, where the productivity increase was 0.40 t/ha, but profitability (100%) and conditional net income (16 593 rubles/ha) were lower than with ammonium nitrate fertilizing by the scattering method in the spring (112% and 18 080 rubles/ha respectively).

Microbial preparations improve mineral nutrition of plants, protect against phytopathogens, and increase their resistance to stress factors. The aim of our research is to study the effect of microbial preparations on the biological activity of rhizosphere and the productivity of oil flax under no-till in the Crimean Steppe. Microbiological analysis of the rhizosphere of oil flax showed that there is a tendency to increase the number of microorganisms of various ecological and trophic groups both under the conditions of the conventional farming system (CFS) and no-till when seeds are inoculated with a complex of microbial preparations (CMP). Under CFS, the number of microorganisms using mineral forms of nitrogen as nutrition increased by 28 %; pedotrophs – by 37 %; ammonifiers and oligotrophs increased under both farming systems. The total number of nitrogen fixers increased by 29 % under CFS as a result of biological preparations use, while under no-till there was only a trend towards increasing the amount of azotobacter. The number of actinomycetes increased under the influence of CMP by 50% under direct sowing; micromycetes decreased under both farming systems. The number of cellulose-degrading microorganisms increased by 18 and 27 % under no- till and CFS, respectively. The yield of oilseed flax under no-till was 0.11 t/ha (12.9 %) higher than under conventional farming system. On average, over three years (2017-2019), an increase in yield amounted to 0.12 t/ha (19%) due to the use of microbial preparations.

Through the period of 1977–2018, studies were conducted on three experimental fields of the Samara State Agricultural Academy with the purpose of studying the influence of the basic elements of the farming system on the weediness and the yield of winter wheat. Experimental schemes included the following options: the type of fallow in the crop rotation (black, seeded and green-manured), fertilizer systems (organic-mineral recommended, organic-mineral intensive and organic) and various methods and depths of soil tillage of fallow lands. Observations and surveys were carried out according to generally accepted methods. The soil of the plots was ordinary chernozem and typical medium-thick loamy chernozem (humus content was from 6.0 to 8.3 %, mobile phosphorus was from 90 to 155 mg/kg, exchange potassium was from 129 to 190 mg/kg, pHsalt was from 6.3 to 6.8). Replacing black fallow with seeded or green-manured fallow increased the weediness of crops 1.4–1.6 times and reduces the yield of winter wheat by 0.29–1.03 t/ha. Organic fertilizer systems significantly changed the weed species compositions and contributed to an increase in the number of perennials by a factor of 3.0, and their masses by a factor of 1.3–1.4 in comparison with organic-mineral fertilizer system. Organic-mineral fertilizer systems did not have a significant effect on the yield of winter wheat. The organic fertilizer system led to a slight (0.26–0.31 t/ha) grain shortage compared with organic-mineral. The methods and depths of soil tillage did not have a practically significant effect on the weediness and yield of winter wheat.

The problem of reducing crop yields during the transition from classical technology of cultivation to the technology without tillage (no-till) can be solved by the most effective use of fertilizers. The purpose of the research was to study the influence of mineral fertilizers on the yield and quality of winter wheat grain under direct sowing in the Stavropol Territory. Studies were carried out in 2015-2019 on the experimental field of the North Caucasus Federal Agricultural Research Centre. Winter wheat was sown using two cultivation techniques for growing crops with and without disturbing the soil through tillage. Preceding crops – pea and sunflower. Fertilizers were added to the rows simultaneously with the Triticum vulgare L. sowing; topsoil dressing was carried out using N52 according to the method of splitting dividers. Options (amount of fertilizers added to the rows): 1. Without fertilizers; 2. N6Р26; 3. N12Р52; 4. N24Р104; 5. N52Р52; 6. N52Р52К52; 7. N52; 8. N104Р52К52. In the third year of direct sowing (2017–2019), winter wheat showed high responsiveness to the addition of all doses of fertilizers in rows. The yield increase in case of pea being preceding crop varied between 0.76-3.06 t/ha; sunflower – 0.51–2.75 t/ha. N104P52K5 contributed to the highest and most stable yield – 6.89 t/ha and 5.92 t/ha after pea and sunflower, respectively. The increase from 1 kg of the active substance of the fertilizer was 14.7 and 13.2 kg of grain. The use of this dose of fertilizer minimized crop losses compared to the first year of wheat cultivation using no-till farming and classical agricultural technique. At the same time, the 3rd and 4th class grain was formed. Higher content of raw gluten compared to other doses of fertilizers was noted likewise: 1.6–9.8 % (preceding crop – pea) and 1.1–11.5 % (preceding crop – sunflower) more. Nitrogen fertilization played a significant role in increasing yields only after sunflower (the average increase was 0.21–0.86 t/ha).

Agricultural technologies aimed at reducing the tillage can be adopted as safer farming methods to preserve and improve the diversity of soil microbial communities. The area under the promising resource-saving no-till system (direct sowing) is increase in the conditions of the Steppe annually. The use of herbicides in such a farming system causes a negative effect on the soil biocenosis. But the introduction of agronomically useful microorganisms into the rhizosphere are increasing the resistance of plants against stress factors, their yields and product quality, and preserving soil fertility. The objective of this research was to assess the state of microbiocenosis of southern chernozem under the influence of no-till system and a complex of microbial preparations. The influence of direct sowing and microbial preparations on the state of microbocenosis of southern chernozem was established. The number of cellulolytic microorganisms increased under the influence of farming systems in comparison with the virgin soil. The use of microbial preparations contributed to an increase in the number of microorganisms of ecological and trophic groups and the representation of the majority of phyla, which also depended on the system of agriculture. A decrease in the representation of Acidobacteria and Verrucomicrobia and an increase in Firmicutes and Proteobacteria were observed in comparison with virgin soil.

Reduced soil tillage is a powerful means to mitigate soil degradation. However, in arid climates, no-till rainfed technologies often result in yield drop due to lack of soil moisture and mineral nutrition. Rainfed production of winter wheat using direct sowing and diversified fertilization in South Kazakhstan was studied in 2019–2020. Eight field-scale treatments using nitrogen and phosphorus fertilizers were studied for biometric parameters of winter wheat. An economic profitability of the amendments used was assessed. The soil managed to accumulate productive moisture to support plants’ needs during formation of productive organs. Use of phosphorus fertilizer at direct sowing accelerated grain maturation, and the combination of phosphorus and nitrogen fertilizer lengthened the growing season. The highest production cost of 1 tonne of grain was in the plots that did not receive any amendments, and the lowest cost was in the treatment with use of plant growth stimulants together with micronutrient fertilizer. For the first time, optimization of the soil nutritional regime with consideration of the biological and phenological demands allowed for the balance of the plant nutrition and cost efficiency of grain production with direct sowing of winter wheat in dry conditions in South Kazakhstan.

Aim. To create bread wheat lines with valuable economic and biological traits as initial breeding material by hybridization of Triticum aestivum L. and Triticum spelta L. Results and Discussion. The study was conducted at Uman NUH. Bread wheat accessions were created by remote hybridization and multiple individual selections. Hybrid offspring F2–5 was analyzed for expression of economically valuable characteristics. In the 5th generation (F5), the best specimens were selected and tested in 2012–2018 (F5–F10). Bread winter wheat variety Podolianka was used as a check variety. The systematic method of arranging plots of 10 m2 was used. The plots were arranged in blocks with a density of 400,000 plants/ha in 5 replications. Biometric measurements were carried out on 50 plants selected from each plot in 2 non-adjoining replications. After observations and measurements, grain was threshed, and the yield capacity was determined. The significance of the study results was evaluated as Ye. R. Ermantraut et al. described (2000).The developed accessions differed in expression of economically valuable traits. The plant height varied within 52–112 cm. Middle and short forms were selected. The gluten content varied within 27.5–38.1 %. The lines were grouped according to the spike shape into 5 different morphotypes: speltoids, forms with a typical bread wheat spike, square heads, subcompactoids and compactoids. Short square head accession 1689 and accession 1692 with a typical bread wheat spike were distinguished by several economically valuable features. Conclusions. Remote hybridization of bread winter wheat with spelt enabled developing over 500 bread wheat lines. Forms combining high performance and high grain quality were selected, in particular accession 1689 containing 32.4 % of gluten, 15.8 % of protein and giving a yield of 7.19 t/ha. Hybridization of bread wheat with spelt created variety Artaplot included in the State Register of Plant Varieties suitable for dissemination in Ukraine in 2019.

Tillage Methods

Despite new cultivation methods, the proportion of conventionally cultivated land is still very high in Hungary.Although these technologies demand more time, labour and fuel, they are still attractive to users because they require less professional skill and simple machinery. In Hungary, conventional tillage methods usually lead to soil deterioration, soil compaction and a decrease in organic content. These side effects have caused gradually strengthening economic and environmental problems.The technologies for those plants which are dominant on Hungarian arable lands use (winter wheat, maize, sunflower and barley) need to be improved both in the interest of environmental protection and the reduction of cultivation costs.The Department of Land Use at Debrecen University is cooperating with KITE Sc. to carry out soil tillage  experiments at two pilot locations to prove tillage technologies already used in the USA.The aim of our examination is to adapt new technological developments and machinery, and to improve them on Hungarian soil for local environmental conditions. With these improved machines, the field growing of plants could be executed by less manipulation and better suited to economic and environmental needs. The most significant task is to investigate and improve the conventional cultivation replacing, new soil-protecting tillage technologies, and to apply no-till and mulch tillage systems.On the basis of the experiments’ survey data, we established that the looseness and moisture content of the soil using reduced tillage is more favourable than after using conventional technologies. The results of no-till and shallow spring tillage are behind those of winter plough or disk ripper cultivation in corn yield and production elements.To preserve moisture content in the soil, the ground clearing and sowing while simultaneously performing no-till method presents the most favourable results. The surplus moisture gained using no-till technology is equal to 40 mm precipitation.Regarding the yield of winter wheat we established that the tillage methods do not affect plant yield. Both disk ripper and conventional disc cultivation showed nearly the same harvest results (5.55 or 5.5 t/ha), where the difference is statistically hardly verifiable from the no-till method. From the individual production of corn and the number of plants planted in unit area,  calculated results prove that no significant difference can be detected between the production of winter plough and disk ripper technology. Although the yield achieved with the no-till method is less than with the previously mentioned technologies, the difference is only 9-10%. We received the lowest production at shallow spring tillage.Evaluations have shown a 1.1 t/ha (13%) difference in the yield of maize, between winter tillage and the disk ripper method, in this case the traditional method resulted in higher yield. In winter tillage, the yield of maize was 1.9-2.1 t/ha (23-25%) higher than in the case of direct sowing and cultivator treatments. No significant difference could be noted between the yields of direct sowing and cultivator treatments.Our research so far has proved the industrial application of reduced tillage methods in crop cultivation technologies.
