The article analyzes the current state and improvement of elements of the technology of growing valuable forage and food crops, spring barley in Ukraine. It is noted that in recent years the area under large crops and the yield of this crop have decreased significantly. It is emphasized that further improvement of technologies should be focused on the transition to more use of biological agents to increase yields. Researchers have shown that the effectiveness of the use of humid preparations GK-6M, GK-4MK, GK-MK - on crops of spring barley Dokuchaivsky 15, due to foliar feeding of plants in the tiller ring phase. The main justification of the article is the results of field research conducted in 2015–2019. Maximum indicators, namely: increase in leaf area by 46–38 %, stem height by 8,3 cm; the number of grains in the ear – 4,8 pieces; ear lengths – 1,9 cm; mass of grain in the ear – 0,33 g; masses of 1000 grains – at 12,0 %; nature of grain – 34,9 g – was obtained by treating plants with humid preparation GK-6M. Foliar feeding of plants in the tiller ring phase with the studied drugs provided the largest increase in the yield of spring barley grain – 1,08 t/ha, provided the use of growth stimulant GK-6M. A slightly smaller effect of foliar fertilization of plants on the yield of spring barley was observed from the growth stimulator GK-4MK – the increase in grain yield was 0,83 t/ha and from the growth stimulant GK-MK – the increase in grain yield – 0,66 t/ha. The obtained increments are significant, mathematically proven. Further improvement of agrotechnologies due to wider use of biological means of increase of productivity and quality of production is offered.

The Impact

Theresearch results are presented conducted during 2016-2018 on southern chernozem with two varieties of spring barley to study the impact of nutrition optimization on grain yield and elements of its structure. It is determined that the treatment of crops with growth regulating drugs in the main growing seasons provides a significant increase in grain productivity of barley, which is the highest when formed by three foliar nutrition with modern growth regulating drugs in the tillering phase and plant emergence in the tube at the beginning of earing. The grain yield of spring barley of the Stalker variety increased on average over three years, depending on the growth regulator taken for processing, in the range of 3.25 – 3.60 t / ha at its level in control, respectively, for treatment of plants with water 2.50 t / ha, and the variety Vakula – to 3.41 – 3.71 compared with 2.47 t / ha in the control. It was found that the increase in grain yield by the studied varieties of spring barley was due to the increase in ear length, and most significantly – due to more grains in the ear, the weight of grain from the ear and the weight of 1000 grains. These indicators increased and changed under the influence of power optimization. Key words: spring barley, varieties, elements of crop structure, grain yield, foliar fertilization, growth regulators.

In order to maximize the potential of productivity of spring barley varieties, it is important to optimize the conditions for plant growth and development, which are, first of all, provided by the latest intensive agricultural technologies, which provide for the correct placement of crops in crop rotation after the respective precursors; optimal supply of plants with nutrients, taking into account their content in the soil; fractional application of nitrogen fertilizers during the growing season by phases of growth and stages of organogenesis; the use of retardants, integrated protection of plants against weeds, pests, diseases, timely and quality implementation of all agrotechnical measures. Research to study the effectiveness of different terms of spring barley sowing and doses of nitrogen fertilizers were conducted during 2018 - 2019 in the conditions of the research field of VSAU v. Agronomichne of Vinnytsia region on gray ashed soils. Weather conditions during the years of the research differed from the average long-term data with high temperature conditions and low rainfall, and accordingly the most favorable year for the growth and development of spring barley was 2018. It is shown the 2-years investigation results on study the effect of sowing dates and nitrogen fertilizations on productivity elements and quality indexes of spring barley grain under conditions of Right-Bank Forest-Steppe on gray forest soils. Accordingly, the highest levels of harvest of barley cultivars at different sowing dates were obtained under conditions of 2018. t should also be noted that the delay of sowing by 6 days in the years of research leads to a decrease in the yield level on average for all varieties by 0,42 – 0,64 t / ha, and a delay of 14 days leads to a decrease by 1,37 – 1,80 t / ha. The use of nitrogen fertilizers leads to an increase in the yield level of both cultivated varieties, and the highest crop yields of the Svarog variety were obtained in the experiment where the background + N60 was applied in the foliar fertilization (4,87 t / ha), and the lowest respectively in the control variant 3,16 t /ha, in the Armax variety a similar situation is observed, however, with lower indicators respectively 4,54 and 3,06 t / ha. The lowest values of protein content in the grain were obtained in the control variant where only N17 P17 K17 was applied to rows when sowing, and the use of nitrogen fertilization leads to an increase in this indicator and the highest values obtained in the variant of experiment 4, where Background (N17 P17 K17) + N60 in the foliar fertilization on the feeding phase of the tube exit. Key words: spring barley, nitrogen fertilizers, elements of the crop structure, yield, quality of production.

Background. Spring barley grain yield and chemical composition depend on mineral fertilization as well as soil and climatic conditions during plant growth. It is especially important to provide fertilization with microelements that are connected with photosynthesis and respiration rate. The aim of this study was to evaluate the effect of foliar fertilization with manganese and copper on grain yield and its components, chlorophyll content in leaves, selected chlorophyll fluorescence indexes, leaf area index (LAI) and the chemical composition of grain in 3 spring barley fodder cultivars and 1 malting cultivar.Material and methods. The field experiment was carried out during 2014‒2016 at the Experimental Station for Variety Testing in Dukla (49o55’ N; 21o68’ E), in a split-plot design in 4 repetitions. The study factors were: 4 spring barley cultivars and foliar feeding (control, Cu and Mn).Results. The foliar fertilizers used in the experiment increased grain yield, ear density, number of grains per ear and 1000 grain weight. The content of chlorophyll in subflag leaves was usually higher in cultivars fertilized with copper compared to manganese, with only the cultivar Suweren having an inverse relationship. Copper application favorably increased the value of the PSII functioning index both compared to the control and to fertilization with manganese. The LAI index was dependent on the cultivar and the foliar feeding. A slight tendency to a higher content of total protein and raw ash on plants fertilized with foliar micronutrients was observed. A larger increase of these contents in comparison to the control was found after the application of copper than of manganese.Conclusion. Spring barley yield, yield structure components, the relative content of chlorophyll in the leaves, LAI index and chemical composition of grain depended on the weather conditions during the plant growing periods. Foliar feeding with manganese resulted in an increase in grain yield and 1000 grain mass when compared to foliar feeding with copper. Copper fertilization resulted in a greater increase in the relative content of chlorophyll in the leaves and a higher content of total protein and crude ash in the grain compared to manganese fertilization. A greater increase in the LAI index compared to the control was observed in plants fertilized with manganese rather than with copper.

The effect of barley seeding rate and row spacing, and triallate, diclofop, and difenzoquat herbicide rate on barley grain yield and quality, and wild oat control were evaluated in field experiments near Bonners Ferry, Idaho, in 1989 and 1990. The purpose of the study was to develop integrated control strategies for wild oat in spring barley. Barley row spacing (9 and 18 cm) did not affect barley grain yield. Barley grain yield was greatest when barley was seeded at 134 or 201 kg ha–1compared to 67 kg ha–1. Wild oat control increased as wild oat herbicide rate increased and barley grain yield was greatest when wild oat herbicides were applied. However, barley grain yield was similar when wild oat biomass was reduced by either 65 or 85% by applications of half and full herbicide rates, respectively. Net return was greatest when the half rate of herbicide was applied to 100 wild oat plants per m2and was greatest when half or full herbicide rates were applied to 290 wild oat plants per m2. Net return increased when the seeding rate was increased to 134 or 201 kg ha–1when no herbicide was applied and when 290 wild oat plants per m2were present.

A field experiment was conducted at Lacombe and Beaverlodge, AB, and Melfort, SK, in 1999 and 2000 to evaluate the effect of seed placement and herbicide application timing on productivity of a general purpose (AC Lacombe) and hull-less (Falcon) barley (Hordeum vulgare L.) cultivars. Barley plant density was often less and dockage greater when seed was spread in a 20-cm band with 28-cm sweeps spaced 23 cm apart compared to seeding in distinct rows with hoe openers spaced 23 or 30 cm apart. Method of seed placement had little effect on barley grain yield or yield was significantly lower with the sweep compared to the distinct rows. Herbicide application timing effects were variable for barley grain yield. Grain yield was often greater and dockage less when herbicides were applied at the one- to two- or three- to four-leaf stage of barley compared to the five- to six-leaf stage. Method of seed placement did not influence barley responses to time of herbicide application with either cultivar. Barley silage yield was mainly higher with the distinct 23-cm row spacing than with the other seed placement methods. Herbicide application timing did not affect silage yield.

Abstract The purpose of the research is to study the effect of the fungicide Lamador and the humic preparation Rostok on the quality of spring wheat and spring barley in the conditions of the northern forest-steppe of the Tyumen region. According to the yield, we found that pre-sowing seeds treatment with Lamador protectant and joint treatment with Rostock contributed to an increase in yield by 0.70 t/ha of spring wheat and 0.15 t/ha of spring barley, in the option with the pre-sowing seeds treatment with Lamador protectant and Rostock preparation by 0.90 t/ha and 0.10 t/ha. The highest yield of spring wheat was noted in the third option – 4.10 t/ha, of spring barley in the second option – 3.52 t/ha. An increase in the thousand kernel weight was noted in the crops under study. The highest thousand kernel weight was observed for spring wheat and spring barley in the third option – 30.2 g and 54.3 g, respectively. The maximum protein content in the spring wheat grain was noted in the third option –13.3%, which is higher than the control option by 1.3%, for spring barley we also noted protein increase by 0.4-0.5%. Thus, the experimental application of the fungicide Lamador together with the preparation Rostok for wheat seeds treatment demonstrated a positive effect of the protectants on plants in the agro-climatic conditions of the forest-steppe zone of the Tyumen region and contributed to an increase in crop yield by 28% for spring wheat and 4% for spring barley, which proved the need for their use in the plant protection system, to increase the productivity and quality of the grain obtained.

SummaryIn experiments over 3 years (1974–6) cow slurry in the range 0–112·5 t/ha and ammonium nitrate in the range 0–120 kg N/ha were applied to field plots factorially to test the effects on the yield and quality of spring barley grain.In 1974 slurry application markedly improved the grain yield (cv. Golden Promise) at each rate of inorganic N and increased grain size. Applying N fertilizer with more than 37·5 t slurry/ha reduced grain yield below the maximum. Grain with the highest crude protein content (15·1 %) was obtained from a combination of slurry and inorganic N. The residual effects of the slurry treatments gave satisfactory grain yields in 1975 without additional fertilizer.Grain yields (cvs Julia and Abacus) in other experiments carried out on a different soil type in 1975 and 1976 were approximately half those obtained in 1974, due in part to drought conditions. The pattern of the results was similar. Heaviest grain yields were harvested from plots receiving 70 t slurry/ha with no additional N.

Abstract The research is devoted to the study of the influence of precursors and mineral fertilizers, applied in various doses, on the agrophysical properties of the soil, the value of the grain yield of spring barley in the soil and climatic conditions of the Central Black Earth region. The field experiment was based on the long-term hospital of Belgorod State Agrarian University named after V. Ya. Gorin. As an object, the variety of spring barley Knyazhich, recommended for the region, was chosen. The soil of the experimental plot is typical chernozem, medium loamy granulometric composition on loess-like loam. The experiment scheme (4×4) provided for the study of four gradations of factor A (predecessors: corn for grain - control, sunflower, sugar beet, soybeans) and factor B (doses of mineral fertilizers: N10P10K10 - control, N30P30K30, N50P50K50, N70P70K70). Growth and development of spring barley plants in 2018-2020 took place in meteorological conditions characterized as arid with a predominance of elevated temperatures and insufficient precipitation during the critical phases of plant vegetation. The results of field experiments established that the water and agrophysical properties (density and structural-aggregate composition) of the soil under the influence of previous crops approached the optimal values and changed insignificantly. Increased doses of mineral fertilizers had a positive effect on the value of the yield of barley grain according to the studied predecessors. The highest grain yield over the years of research was obtained at high N50P50K50 and intensive N70P70K70 backgrounds for the predecessors of soybeans and sugar beets and amounted to 5.48 and 5.03 t/ha and 5.33 and 5.32 t/ha, respectively. This was higher than the control of corn for grain 0.82 and 0.37 t/ha and 0.62 and 0.61 t/ha, while for sunflower it decreased to 4.06 and 4.71 t/ha and was at the level with the control.
