“…Позакореневі підживлення посівів можуть стати ефективним агротехнічним заходом у забезпеченні рослин мікроелементами упродовж вегетації. У посушливих умовах степової зони вони особливо ефективні, оскільки збільшують доступність поживних речовин і стимулюють їх засвоєння рослинами з ґрунту [9].…”

Землеробство, рослинництво, овочівництво та баштанництво favorable conditions for forming the highest grain yield and high level of crop profitability. For example, on average in the years of researches, in wheat plants of winter variety Zamozhnist, under this variant of fertilizer the grain yield at the level of 4.99 t/ha was formed, and the conditionally net profit per 1 ha of crops in the above mentioned variant was UAH 17484.5, and the profitability level was 127.6%, which exceeded the variant without fertilizers when growing the same variety by 58.2 and 56.2%, respectively. Growing the variety Zamozhnist provided the lowest cost per unit of production for fertilizing Escort-bio crops against the background of mineral fertilizers, where it amounted to 2746.1 UAH / t, which is 18.1% less than for winter wheat in control without fertilizers. Formation of grain yield and economic efficiency indicators of winter barley cultivation depended on the variety and microfertilizers. It was found that the pre-sowing treatment of the latter seeds contributed to 5.97-6.84 t/ha of grain. At the same time, the highest rates of economic efficiency of cultivation were recorded for the cultivation of the Deviatyi Val variety and the use of fertilizers Mifosat-1 and Chelat Kombi. Thus, the conditionally net income for this variant of experience was the highest and amounted to 17108,4 UAH / ha. It should be noted that the cost of growing grain of winter barley of the Deviatyi Val was 2298.8 UAH / t, which provided a level of profitability of 108.8%.

“…The use of plant growth-regulating drugs on winter wheat and other crops is a common practice (Panfilova and Gamayunova, 2018;Yeremenko et al, 2018). Thus, in the UK, the use of plant growth-regulating drugs in the spring vegetation period contributed to the growth of grain yield by 4 t / ha, compared with the natural background (Griffin and Hollis, 2017 ).…”

The article presents the results of studies conducted in 2011-2016 years on the southern chernozem in the southern Steppe of Ukraine, studied the efficiency of processing winter wheat crops modern growth-regulating drugs in the main periods of vegetation of the crop on the background of mineral fertilizers application. It was determined that the introduction of pre-sowing cultivation of winter wheat fertilizer in a dose of N 30 P 30 (background) and the use of foliar fertilizing of crops at the beginning of the resumption of spring vegetation and the beginning of stooling complex organic fertilizers Organic D2 and Escort-bio created favorable conditions for the formation of optimal indicators of the structure of the crop and, accordingly, a high level of grain yield of the studied varieties. In the variants of fertilizer Organic D2 and Escort-bio plants of winter wheat variety Kolchuga formed 4,42-4,48 t / ha of grain, and plants of Zamozhnist formed 4,96-4,99 t/ha, which exceeded the control by 52,9-55,0 and 62,6-63,6%, respectively. From the studied varieties of winter wheat on a set of indicators, it was determined Zamozhnist as the best variety.

The article presents the results of three-year studies on the influence of various variants of the nutrition system on the field germination of seeds, the viability and survival rate of spring barley plants in the Southern Steppe of Ukraine. Formulation of the problem. Analysis of the spring barley yield in Ukraine indicates a significant lag behind the leading agrarian countries of the EU. Now there is a tendency for a gradual increase in its yield in Ukraine, in particular in 2018, 2019 and 2020 it was 2,75, 3,25 and 3,27 t/ha. At the same time, it is still half as much in comparison with the leading EU countries, which is why there is a need to look for ways to increase the yield of spring barley in specific growing conditions. The purpose of the research was to determine the effect of various options for the main application of complex fertilizers and foliar dressing with various options for a mixture of urea, biostimulant and polymer fertilizers on field germination of seeds, viability and survival rate of spring barley plants in the conditions of the Southern Steppe of Ukraine. Research methodology. The studies were carried out during 2018–2020 on the fields of the educational and experimental farm of the separate structural unit "Novokakhovskiy specialized college of the DmytroMotornyiTavria State Agrotechnological University", located in the central part of the Kakhovka district of the Kherson region. The two-way experiment was carried out by the split-section method in four repetitions and two tiers. Five options for the main application of mineral fertilizers and five options for foliar dressing were studied. The sowing area was 120 m2, and the counting area was 80 m2. Research results. In the course of the research, a tendency to increase the indices of field germination of seeds was established for all variants of the main application of complex fertilizers. It was the highest on the options for using ammonium nitrate phosphate fertilizer at the rate of N30P30K30 and N60P60K60 82.9 %, which is almost 2,0 % higher than in the control. The main application of fertilizers and foliar dressing, by improving nutrition and leveling exogenous stresses, significantly increased the viability and survival rate of spring barley plants. By optimizing the feeding system (variant of the main application of ammonium nitrate phosphate fertilizer N60P60K60, followed by two foliar dressings: during microphase 31 with a mixture of carbamide (N10 kg/ha), Efisoil Renovation at a dose of 0,4 l/ha and Folik Micro at a dose of 1,5 l/ha and during microphase 39 with a mixture of Efisoil Renovation at a dose of 0,4 l/ha together with Folik Micro at a dose of 3,0 l/ha), the safety and survival of plants was 5,6 and 10,5 % higher, respectively, than in the control. Thus, the optimization of the feeding system of spring barley, even under the condition of the same indicators of all other elements of the yield structure, only due to the higher survival rate of plants, provides an increase in grain yield by more than 10,0 %. Key words: spring barley, main fertilization, foliar feeding, field germination, viability, survival rate.
