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. Keywords: spring barley, plant growth stimulants, foliar feeding, yield.

Abstract The potential to increase barley grain yield lies in the indeterminate nature of its inflorescence meristem (IM). The IM produces spikelets, the basic reproductive unit in grasses, which are linked to reproductive success. During early reproductive growth, barley spikes pass through the maximum yield potential—a stage after which no new spikelet ridges are produced. Subsequently, spikelet abortion (SA), a phenomenon in which spikelets abort during spike growth, imposes a bottleneck on increasing the grain yield potential. Here, we studied the potential of main culm spikes by counting potential spikelet number (PSN), final spikelet number (FSN) and computed the corresponding SA (%) in a panel of 417 six-rowed spring barleys. Our phenotypic data analyses showed a significantly large within- and across-years genotypic variation with high broad-sense heritability estimates for all the investigated traits, including SA. Asian accessions displayed the lowest SA indicating the presence of favorable alleles that may be exploited in breeding programs. A significantly negative Pearson’s product-moment correlation was observed between FSN and SA. Our path analysis revealed that PSN and FSN explain 93% of the observed phenotypic variability for SA with PSN behaving as a suppressor trait magnifying the effect. Based on a large set of diverse barley accessions, our results provide a deeper phenotypic understanding of the quantitative genetic nature of SA, its association with traits of high agronomic importance, and a resource for further genetic analyses.

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.

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.

AbstractGranular treatments of thiofanox (Dacamox 10 G®) and carbofuran (Furadan 10 G®) and spray treatments of dimethoate (Cygon 4E®) and pirimicarb (Pirimor 50 WP®), all gave good control of cereal aphids and increased barley grain yield significantly above controls.The granular treatments did not significantly reduce parasites and predators of the aphids. Predators and parasites showed a reduced population 1 week after foliar insecticide applications. However, pirimicarb showed a relatively reduced effect compared with other pesticides on the available predatory species, 2 weeks after spraying.

The effect of aluminium (Al) toxicity of either surface or subsurface soil on the growth of barley, and the potential for variation in response to soil acidity among agronomically adapted Australian barley genotypes, were examined at 13 sites. The effect of Al toxicity was investigated by plant analysis, using 3-5 lime application rates and Al-tolerant species (wheat, triticale), as well as barley. All cereals were supplied with complete nutrients. To measure the potential for response variation, grain yields of 14 genotypes of barley, relative to cv. Stirling, were related to soil pH at 7 sites. Grain yield of barley was increased 9-30% at 6 sites, by lime application alleviating A1 toxicity. The yield of triticale and wheat cv. Aroona was not increased by lime application at any site. There was some indication that subsurface acidity may be reducing the grain yield of barley at sites with CaCl2-extractable Al concentrations of 23-4 mg/g in the A2 horizon. Some barley genotypes appeared to be more tolerant than Stirling to soil acidity. Aluminium toxicity appears to be reducing barley grain yields by more than 10% at surface soil pH <4.5 (0.01 mol CaCl2/L), or when CaCl2-extractable Al is >3-4 mg/g. CaCl2-extractable A1 in the surface soil was not a better indicator of Al toxicity than soil pH.

Relevant Factors

The suitable management of nitrogen (N) fertilization can increase barley grain yield, since it is the nutrient required in greater quantity. In this sense, the source and timing of nitrogen application are relevant factors. The objective was to evaluate the effects of N sources and splitting on the performance of barley. The experiment was carried out under a clayey Cambisol (550 g kg-1), in Curitibanos, Santa Catarina. Factorial randomized blocks were used: three mineral sources of N: urea (45% N); urea with urease inhibitor-NBPT (45% of N) and nitrate (30% of N), associated with two nitrogen splitting fertilization: i) split of the rate of N in two seasons: beginning of tillering and full tillering and ii) single application at full tillering. 100 kg ha-1 of N were applied. There was no interaction between the factors and there was no effect of treatments for plant height, ear length, grains per ear, ears per m² and mass of a thousand grains. Yield was influenced by the N source, where nitrate exceeded the yield from amidic sources by 16%. The splitting of N in two times did not present advantages over the single application. Urea with NBPT was not viable in relation to readily soluble forms of N, with the highest yield obtained with a nitric source.

Properties Of Soil

There is uncertainty about the type of mulch to use to reduce soil nutrient depletion and water loss and at the same time enhance crop yield that will also be influenced by the materials available locally for use and their management. The objective of this study was to investigate the effect of mulch application on barley grain yield and physicochemical properties of soil in Negele Arsi district, Central, Ethiopia. Experimental plots were laid on farmers fields’ in randomized complete block design by taking farmers field as a replication. Five farms of each with a currently mulched plot, a year ago mulched plot with perennial mulch and conventional fields as control (15plots of 10m in width and 20m in length in general) were selected for the establishment of the experiment. Subplots of 1mx1m at each corner and a center of each main plot were used for taking barley grain yield and soil data. A total of 30 soil samples collected from two depth layers: 0–20 and 20–40cm were air-dried and passed through a 2 mm sieve to remove roots, and large organic residues. Soil organic carbon concentration in the soil samples was determined by Walkley and Black method. The soil data were subjected to a two-way ANOVA analysis using the general linear model Procedures of SAS. The pairwise comparison method was also used to assess the mean difference of the treatment types and depth levels depending on soil properties. The average barley grain yield obtained from plots mulched with perennial mulch in 2018 (1.52±0.209kg) was higher than plots mulched in 2017 (1.48±0.135kg) and conventional farmland plots (1.44±.0962kg). The overall mean SOC stock was found to be higher under plots mulched in 2018(49.8291±17.9301) and lower in soils under conventional farm plots (39.1182±13.5183) than another treatment type. The highest overall mean of soil carbon stock under plots mulched in 2018 indicates that perennial mulch might be the remedy for replenishing the declining soil fertility on conventional farmlands and to increase barley grain yield on a sustainable basis.
