in arid conditions of the growing season, the use of growth regulators of the retardant type Moddus, CE and Hardy, P on barley crops reduces the lodging of plants and reduces the yield of spring barley. When treating seeds with Moddus, CE, the most intense shortening of the first and second internodes was noted (24 and 7%, respectively), while the diameter of the stem of the 2nd internode increased slightly compared to the control variant. Seed treatment with Moddus, CE reduced lodging by 3%, and treatment in the DC phase 0 (seed treatment)+DC 25-29 (mid-end tillering phase) proved to be ineffective, where the lodging of plants increased the lodging on the control variant.The treatment of seeds with Hardy, P at a dose of 50 ml / t, as well as the treatment of plants at a dose of 300 ml / ha more intensively affected the length of the second internode, reducing it by 22% and 3%, respectively, relative to the control. When processing Hardy plants, P lodging decreased by 12%, while when processing plants with Moddus, CE by only 5%. In conditions of lack of moisture during the growing season, the use of retardants led to a decrease in the yield of barley grain by 7 - 39%. A minimal decrease of 0.3 t/ha was observed in the variant with the treatment of seeds and plants with Hardy, P at a dose of 100 ml/t+300 ml/ha.

The effectiveness of the use of a tank mixture of siliplant micronutrient fertilizer with an insecticidal dressing agent Cruiser KS and siliplant microfertilizers with growth regulators, micro- and organomineral fertilizers has been revealed. It was found that when the seeds were treated with a tank mixture with an insecticidal dressing agent Kruiser, KS (0.5 l / t) with Siliplant micronutrient fertilizer (60 ml / t), the germination energy of barley seeds increased by 2.2%, laboratory germination - by 4.0%, and the strength of growth - by 4.0% compared with the dressing agent Kruiser, KS, and when processing plants in the phase of 3 leaves with siliplant with epin extra, the greatest increase in the yield of barley grain of the Mikhailovsky variety was obtained - 3.5-4.1 c / ha. The use of siliplant with micronutrient fertilizer cytovit turned out to be effective, where the yield increase was 3.1-3.7 c / ha, siliplant with zircon - a yield increase of 3.3-3.6 c / ha, and siliplant with organic mineral fertilizer ecofus, where the yield increase amounted to 2.4-3.4 c / ha.

The results of the conducted studies have shown that spring barley under different meteorological conditions of the growing season reacts differently to the treatment with growth regulators and the introduction of biofertilizers. In conditions of lack of moisture, the treatment of plants with growth regulators does not reduce the height of plants, but at the same time reduces the yield of the crop, depending on the type of retardant, by 0.82-1.52 t / ha. HEFC, BP and Hardy, R. have a significant effect on the yield in arid conditions. Moreover, the use of the drug Hari in its pure form reduces the yield of barley by 0.9 t / ha, and with the combined use of the drug Hardy, P with biofertilizers, the yield of barley practically does not decrease.

The article discusses a method for diagnosing nitrogen nutrition of spring barley (Hordeum vulgare L.) in different phases of the growing season using a photometric device (N-tester) Yara. The studies were carried out in the conditions of the Moscow region (Russia) on the Mikhailovsky spring barley variety on sod-podzolic medium loamy soils with a high and medium content of phosphorus and potassium and a low content of humus (1.9). The agrometeorological conditions of the growing season of spring barley were characterized by sharp fluctuations in air temperature and the amount of precipitation over decades of the month and in comparison with average long-term observations. Abundant and prolonged precipitation during the grain ripening phase led to lodging in most of the experiments, which affected the yield. To diagnose crops, a model experiment was laid with the introduction of increasing doses of nitrogen fertilizers into pre-sowing cultivation with a step of 30, at which the dose of nitrogen ranged from 30 to 150 kg/ha. Diagnostics was carried out in three phases of vegetation: tube emergence ((Z42), earing (Z55), milk ripeness of grain (Z73) with the Yara N-tester and with the help of stem diagnostics according to the modified method of V. Zerling. The results of photometric diagnostics in the stemming phase (Z42) have a strong correlation with the yield of spring barley grain and with the results of stem diagnostics (R = 0.85). Wherein, the N-tester readings in the earing phase (Z55) and milk ripeness of grain (Z73) with yield R = 0.23 and R = 0.17, respectively, have a weak correlation. This is possibly due to lodging of crops and a change in yield, not as a result of poor plant nutrition, but with difficult mechanized harvesting.

The research purpose is to study the effect of systematic application of various doses of mineral fertilizers on productivity, grain quality, value of spring barley productivity elements, determine an optimal doses of nitrogen, phosphorus and potassium in the arid conditions of the Middle Volga region. Improving nutrition with the use of fertilizers contributed to an increase in productivity values. The average yield was 0.18–0.76 t/ha. The use of maximum doses of nitrogen, phosphorus and potassium did not increase productivity in arid conditions. Nitrogen plays a leading role in increasing barley productivity. The agronomic effectiveness of fertilizers depended on the doses of active substances. An increase was 2.1–5.8 kg of barley grain per 1 kg of active substances. The most stable increase was observed when applying N60Р0-60К0-30. Rational doses are as follows: nitrogen 60–90 kg a.e./ha when applying P60K30, phosphorus 30–60 kg a.e./ha when applying N60K30, potassium 30 kg a.e./ha when applying N60Р60. The best option is N60Р0-60К0-30.

The Impact

The study of the impact of huminatrin on the yield and quality of barley grain in the subtaiga zone of the Omsk region on gray forest soils in 2019-2020 showed that the treatment of seeds and feeding of barley during the growing season with the fertilizer “Guminatrin” significantly increased the yield and protein content in the grain. The combination of increased productive tillering, the number of grains in a spikelet and the mass of 1,000 seeds contributed to the formation of the highest yield in the variants with seed treatment and fertilizing during the growing season with fertilizers “Universal huminatrin” with a high content of zinc and “Universal huminatrin” with an amino acid. The highest yield on average for 2 years of research equal to 5.08 t/ha was achieved by the use of the universal huminatrin fertilizer with high zinc content. Treatment of seeds and plants of barley during the growing season with huminatrin increased not only the yield but also the quality of the grain, specifically, the increased protein content.

The aim of the study was to determine the dependence of brewing quality of spring barley grain in terms of indicator of Kolbach number depending on the eff ect of foliar nutrition of plants during the growing season with micronutrients Wuxal on different backgrounds of mineral fertilization. Effectiveness of the infl uence of foliar nutrition of spring barley plants by microfertilizers Wuxal during the growing season on the brewing quality according to the Kolbach number was established. It is revealed that the eff ectiveness of the technological agricultural measure carried out depends on the number of agri-receptions, the rate of microfertilizers and the background of mineral nutrition. It was proved that when growing barley on the background of mineral nutrition N30P45K45 the best results were obtained with two and three times application of microfertilizers at the rate of 1.5 l/ha in accordance with the phenophases of tillering, stem elongation and fl owering. Maximum productivity on the background of N60P90K90 mineral nutrition is achieved by providing three times of crops spraying with a solution of microfertilizers in the amount of 2.0 l/ha each time in accordance with the above-mentioned phenophases of barley plants growth and development. The efficiency of foliar nutrition of spring barley plants by microfertilizers depends on the technological scheme of application, namely on the number of methods of the agro-measure carried out at the respective phenophases of development. The variants of double application microfertilizers were the best in growing barley on the background of mineral nutrition N30P45K45, – Wuxal P Max 1.5 l/ha during tillering and Wuxal Grain 1.5 l/ha at the beginning of flowering; Wuxal Grain 1.5 l/ha during the stem elongation and Wuxal Grain 1.5 l/ ha at the beginning of flowering. The optimal variant for three-times foliar nutrition of plants with microfertilizers was as follows: Wuxal P Max 1.5 l/ha during tillering, Wuxal Grain 1.5 l/ha during of stem elongation and Wuxal Grain 1.5 l/ha at the beginning of flowering, where the highest Kolbach number is obtained – 47.7; 47.5 and 48.0 %, respectively. On the background of N60P90K90 mineral nutrition, the highest parameters were established for three-time spraying of plants with microfertilizers Wuxal P Max 2.0 l/ha during tillering, Wuxal Grain 2.0 l/ha during of stem elongation and Wuxal Grain 2.0 l/ha at the beginning of flowering – 46.9 %. Key words: spring barley, grain quality, Kolbach number, microfertilizers, foliar nutrition.

Sowing Seed

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

It was revealed that on average during the growing season, when the norms of mineral fertilizers were increased, the area of leaf plates increased and, as a result, the increase in green mass growth relative to the control variants increased by 56.3 % at (NРК)30, 82.3 % at (NРК)60, and 126.7 % at (NРК)90. The introduction of mineral fertilizers also influenced the formation of the crop structure. There was an increase in the tillering coefficient of varieties by 15.7%, 5.7 % and 21.3 % (Vladimir, Reliable and Yaromir, respectively) relative to the control, an increase in the number of grains in the ear from 15.1 to 22.4 PCs., the weight of 1000 grains from 48.0 to 55.7 g. and the weight of grain per ear from 0.7 to 1.2 g. There was a strong correlation between the doses of mineral fertilizers and the grain yield from + 0.80 to +1.0, and the variability was calculated.
