Biological Effectiveness

The effect of the use of herbicide mixtures on the reduction of weeds and preservation of barley yield was studied. The experiment (2018–2019) was carried out on dark gray forest soil in the foreststeppe conditions ofTyumenregion. The experiment included two types of basic tillage: moldboard (plowing with a Lemken rotary plow at 20–22 cm) and non-moldboard (tillage with a Smaragd unit at 12–14 cm). The object of research was spring barley, Abalak variety. Biological effectiveness of herbicides, regardless of the soil tillage system, was 94–97% against dicotyledonous weeds, and 80–100% – against cereal and perennial weeds. Efficiency against the entire weed component reached 95–97.5% in 1 month after the application of herbicides, and 96–99% at the end of the growing season. The effectiveness of the use of preparations against cereal weeds was 80–90%, and the effectiveness of herbicides against dicotyledonous weeds – 97–99%. The reduction in the mass of weeds was 90–99%, mostly due to non-moldboard soil tillage. The yield level in the years of research largely depended on the soil tillage with a difference of 0.3–0.4 t in favor of moldboard system and the complex of herbicides applied. A high increase in the yield was provided by a mixture of herbicides Esteron, Speaker + Avantix Extra, Primadonna + Granat + Ovsyugen Super, which amounted to 1.16–1.22 t/ha. The application of comprehensive protection means increased the grain harvest by 1.7 t/ha.

The investigations were carried out in 2014-2015, on a light gray forest heavy loamy soil. The humus content in the arable layer was 5.9%. The mobile phosphorus was 162 and exchangeable potassium was 172 mg per kilogram, respectively, pH of salt extract was 5.6. The total area of the plot was 200 m2, the discount area - 150 m2. Replication - fourfold, placing of plots was successive. Experience scheme: Factor A - preplant soil tillage: 1. Cultivation - 10-12 cm. 2. Milling – 10-12 cm. Factor B – fertilizers: 1. Without fertilizers (control). 2. Fertilizers, aimed to 4.0 tons per hectare (N120P75K90). The following varieties were used as the object of the study: Kornet, Kristal and Nemchinovskaya 56. The norms of fertilizers is calculated by the balance method, based on their removal from the crop and in the soil. The options, treated with a cultivator, were the most clogged. There are no significant difference among tested varieties of Kornet, Nemchinovskaya 56 and Kristal, but Nemchinovskaya 56 was the most clogged - 36 units per square meter, and less weedy was Cornet. When milling , the most clogged was Nemchinovskaya 56 variety - 30 units per square meter. In the way of without fertilization (control), Kristal variety was the most clogged - 21 units per square meter. The weed infestation of winter triticale at the beginning of growing season of Kristal variety was more to 21.3%, Nemchinovskaya 56 variety to 17% and Kristal to 21.6% more, than in milling. At the end of the growing season of winter triticale during cultivation the weeds increased by 71% and 74%. The same pattern was preserved debris perennial weeds early in the growing season 2.4-4.2 units per square meter, at the end of the growing season 4.6-4.7 units per square meter. The most clogged varieties were Nemchinovskaya 56 – 2.8-4.6 units per square meter and Kristal 2.7-4.7 units per square meter.

SUMMARYField experiments were conducted between 2009 and 2011 in Ireland to compare the effects of soil tillage systems on the grain yield, nitrogen use efficiency (NUE) and nitrogen (N) uptake patterns of spring barley (Hordeum vulgare) in a cool Atlantic climate. The four tillage treatments comprised conventional tillage in spring (CT), reduced tillage in autumn (RT A), reduced tillage in spring (RT S) and reduced tillage in autumn and spring (RT A+S). Each tillage system was evaluated with five levels of fertilizer N (0, 75, 105, 135 and 165 kg N/ha). Grain yield varied between years but CT had a significantly higher mean yield over the three years than the RT systems. There was no significant difference between the three RT systems. Tillage system had no significant effect on the grain yield response to fertilizer N. As a result of the higher yields achieved, the CT system had a higher NUE than the RT systems at all N rates. There was no significant difference in NUE between the three RT systems. Conventional tillage had significantly higher nitrogen uptake efficiency (NUpE) than RT A and a significantly higher nitrogen utilization efficiency (NUtE) than all three RT systems. Crop N uptake followed a similar pattern each year. Large amounts of N were accumulated during the vegetative growth stages while N was lost after anthesis. Increased N rates had a positive effect on N uptake in the early growth stages but tended to promote N loss later in the season. The CT system had the highest N uptake in the initial growth stages but its rate of uptake diminished at a faster rate than the RT systems as the season progressed. Tillage system had an inconsistent effect on crop N content during the later growth stages. On the basis of these results it is concluded that the use of non-inversion tillage systems for spring barley establishment in a cool oceanic climate remains challenging and in certain conditions may result in a reduction in NUE and lower and more variable grain yields than conventional plough-based systems.

The article offers studies to determine the effectiveness of processing methods for the productivity of spring rapeseed and surepitsa on the dark gray forest soil of the Ryazan region. As a result, it was revealed that the maximum intensity of decomposition of flax tissue was recorded in the steam link of the crop rotation using the dump method of basic tillage for oilseed cabbage crops. The maximum yield of rapeseed was observed on the variant of the steam link of crop rotation + dump processing (31.3 c / ha), in the surepitsa (25.6 c/ha). A high increase in oilseeds in this variant is 4.7 c / ha, where the NSR05 factor with 0.97 c / ha relative to the minimum basic tillage was recorded in 2015. In the experiment, the trends of increasing the yield of oilseeds of spring rapeseed and surepitsa in the fallow link of the crop rotation relative to the row crop are revealed. The maximum oil content of rapeseed was noted in the rowed link of crop rotation during milling tillage (47.6%); in surepitsa – in the rowed link of crop rotation also during milling (45.1%).

The work is devoted to assessing the effect of a single oil pollution of the soil on the yield and chemical composition of spring barley plants during four rotations of crop rotation. The study was conducted in 2004-2018 on the experimental field of Agrochemistry and Soil Science Department of Kazan State Agrarian University, located in the ancestral zone of the Republic of Tatarstan. The soil of the experimental plot is gray forest medium loamy, which is the prevailing soil difference for this zone. Uncontaminated soil was characterized by a low humus content and a slightly acidic reaction of the medium, an increased content of mobile phosphorus and an average supply of mobile forms of potassium and trace elements (B, Mo, Mn, Cu, Zn, Co). The soil was artificially contaminated with salable oil at the rate of 20 l/m2, which, as shown by previous studies of the department, corresponds to the average level of pollution. The effect of oil pollution of gray forest soil on the productivity of barley sown 2, 6, 10 and 14 years after pollution was studied. A statistically significant decrease in the yield of spring barley was established within 14 years from the moment of contamination. As the pollution ages, the yields on contaminated soil gradually approach the yield level of the control (uncontaminated) soil. In all years of observation, a decrease in grain yield from oil pollution of the soil was more significant than a decrease in straw yield. Old oil pollution of gray forest soil had a weak effect on the content of total nitrogen, phosphorus and potassium in the plants of spring barley. The spring barley utilization rates of mineral nitrogen and mobile phosphorus in gray forest soil under the influence of old oil pollution decreased by about 1/4, and mobile potassium by 1/5.

The paper presents the results of research into the effect of different soil tillage systems on soil density and structure. The research was conducted in a long-term stationary experiment on the crops of Nikita spring barley. The soil of the experimental plot is classifi ed as leached, mediumtextured, medium-humus, heavy-loam chernozem. The following soil tillage systems with peas as a forecrop were studied: deep moldboard, deep combined, minimum combined and zero. The years of research (2015-2018) differed in heat availability and amount of precipitation. This allowed to study and carry out comparative assessment of the effect of various soil tillage systems of leached chernozem on agrophysical properties of soil. Yearly weather conditions had no signifi cant effect on soil density with all the studied soil tillage systems in single and binary crops of spring barley, whereby the indicators varied from 1.87 to 6.72%. Compared to deep moldboard tillage (control), there was an increase in soil density with zero tillage in singlecrop sowings of spring barley by 6.2%, and in binary crops – by 9.4%. However, the indices were not beyond optimum values of 1.02-1.05 g/ cm3. The optimum equilibrium soil density for the main subtypes of chernozems is 1.0-1.25 g/cm3. Minimum combined soil tillage system resulted in the stable content of valuable structural soil units 0.25-10 mm both in single-crop and binary sowings of spring barley at 68.3% and 68.9%, and the coeffi cient of soil structural properties – 2.15 and 2.21 respectively. It was established that the effect of soil tillage system on the creation of valuable structural units in soil was 21.4%, yearly weather conditions – 11.8%, type of crops – 25.5%.

The study concerned the determination of nitrous oxide (N<sub>2</sub>O) emissions under conventional and reduced tillage conditions. In the reduced cultivation, a soil cultivating seed drill was used for simultaneous sowing of seeds and subsurface application of fertilizer. The emission levels of the gas tested were dependent on the year of the study and the method of soil tillage, and were subject to considerable changes during the growing season. The use of reduced soil tillage significantly limited emissions of the analysed gas into the atmosphere. Depending on the year of the study, N<sub>2</sub>O emission in the reduced tillage system was from 15% to 40% lower than in the conventional system. Low levels of easily mineralized components in soil could have been the cause of the reduction in N<sub>2</sub>O emissions to the atmosphere.

Aim. The comparison of the effect of hydrothermal conditions and various agricultural practices on the emission of CO 2 from chernozems in the Left-Bank Forest-Steppe of Ukraine. Methods. The dynamics of the intensity of carbon dioxide emissions from chernozem calcic (typical chernozem – in Ukrainian classifi cation) was studied during the growing season of 2011–2012. The observations were based on two fi eld experiments with various methods of soil till- age (6–7 years from the beginning of the experiment) and fertilization systems (21–22 years from the beginning of the experiment). Particularly, plowing at 20–22 cm, disking at 10–12 cm, cultivation at 6–8 cm and direct seeding using Great Plains drill were studied among the soil tillage methods. Mineral system (N 45 P 50 K 45 ), organic system (manure 8 t/ha) and combined organic-mineral system (manure 8 t/ha + N 45 P 50 K 45 ) were studied among fertilization systems. The intensity of CO 2 fl ux was determined using the non-stationary respiratory chambers by the alkaline absorption method, with averaging of the results during the day and the frequency of once a month. Results. During the warm period, the emission of carbon dioxide from the soil changes dynamically depending on temperature and humidity. The maximum of emission coincides with the periods of warm summer showers in June-July, the minimum values are characteristic for the late autumn period. The total emission losses of carbon in chernozems over the vegetation period ranged from 480 to 910 kg/ha and varied depending on the methods of tillage ± (4.0–6.0) % and fertilization systems ± (3.8–7.1) %. The changes in the intensity of CO 2 emission from the soil under different methods of soil tillage are associated with hydrothermal regime and the depth of crop residues location. The biggest difference is observed im- mediately after tillage, but in the spring period the differences are only 12–25 %, and after drying of the top layer of soil become even less. Direct seeding technology provides the greatest emission of CO 2 from chernozem, which is fa- cilitated by better water regime and more complete mineralization of plant residues on the soil surface. Annual losses of carbon are the least under disking of soil at 10–12 cm. The changes in the intensity of CO 2 emission from the soil under different fertilization systems are associated with the involvement of the additional organic matter from plant residues and manure to the microbiological decomposition. The greatest emission was observed under the organic- mineral fertilization system, which increased the loss of carbon by 7–8 % in comparison with the mineral system in the unfavorable hydrothermal year and by 11–15 % in the more favorable year. These differences are observed mainly during the fi rst half of the growing season when there is a clear tendency to increase the intensity of soil respiration. Conclusions. The hydrothermal conditions of the warm period of the year are decisive in the formation of the CO 2 emission fl ow from chernozems. Due to the improvement of agricultural practices, emissions might be reduced but not more that by 15 % of natural factor contribution.
