Barley is one of the most important cereals growing in the Czech Republic. In this paper, we have evaluated how different fertilizer treatments (Control, N1 – 30 kg ha−1 N, N2 – 60 kg ha−1 N, NPK1 – 30, 60, 80 kg ha−1, respectively, NPK2 – 60, 60, 80, and NPK3 – 90, 60, 80) affected spring barley grain yield under different soil–climate conditions (Caslav–degraded Chernozem, Ivanovice–Chernozem, Lukavec–Cambisol) between the years 2013 and 2016. The agronomic efficiency (AE) and the effect of the fertilizer treatments (Control, N2, NPK2) on soil properties (pH, P, K, Ca, Mg, Cox, Nt) were also evaluated. The spring barley grain yield was significantly affected by the fertilizer treatment and soil–climate conditions. Two different models (quadratic and linear-plateau) provided the maximum and reasonable doses of N, according to the soil–climate conditions. Application of mineral P and K slightly increased the AE. The regular application of mineral P and K fertilizers led to an increase in the P and K concentration in the soil, which maintains soil fertility and prevents soil depletion.

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 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.

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.

In Sub-Saharan Africa (SSA), acidic soil covers 29% of the total area. About 13% of the Kenyan total land area has acidic soils, widely distributed in croplands of the central and western Kenyan regions. The high soil acidity, coupled with soil nutrient depletion, negatively affects crop productivity in the region. We conducted an on-farm experiment to determine the effect of lime, manure, and phosphatic fertilizer application, either solely or combined, on soil chemical properties, maize yield, and profitability in acidic soils of Tharaka Nithi County, Kenya. The treatments were different rates of manure, lime, and P fertilizer. The experiment was designed as a randomized complete block design replicated ten times in farmer’s fields. Soil sampling was done at a depth of 0-20 cm prior to the start of the experiment, after crop harvest of SR2016 and LR2017 seasons. The samples were analyzed in the laboratory following standard methods. Results showed that lime significantly increased soil pH by 10.6% during the SR2016 and by 17.7% during the LR2017. Similarly, treatments with lime reduced exchangeable acidity and increased soil available P. Treatments with inorganic fertilizers had significantly higher maize grain yield in comparison with treatments with the sole application of lime, manure, and lime + manure. Lime + fertilizer + manure treatment gave the highest average maize grain yield (5.1 t ha−1), while control gave the lowest (1.5 t ha−1) during the LR2017 season. Economic returns were low due to the prevailing low rainfall experienced during the study period during the SR2016 season. Lime combined with inorganic fertilizer treatment recorded the highest returns (128.75 USD ha-1) followed by sole inorganic fertilizer (105.94 USD ha-1) during the LR2017 season. The study recommends a combination of both lime and inorganic fertilizer for enhanced maize production and profitability in Tharaka-Nithi County, Kenya.

If available to farmers, potatoes represent a crop classically fertilized with farmyard manure in the Czech Republic. At the same time, potatoes are a crop sensitive to soil–climate conditions. We evaluated the effect of cattle manure (FYM), manure and mineral nitrogen (FYM + N1, FYM + N2), manure and mineral fertilizers (FYM + N1PK, FYM + N2PK, FYM + N3PK) application and the effect of three soil-climatic conditions (Caslav—maize production area with degraded Chernozem, Ivanovice—maize production area with Chernozem, Lukavec—potatoes production area with Cambisol) over four years (2016–2019) on potatoes yield and soil chemical properties. Of all the factors, yields were most affected by location. Lukavec provided the highest average yields (37.2 t ha−1), followed by Ivanovice (23.5 t ha−1) and Caslav (15.5 t ha−1). The second most important factor was the climatic conditions of the year. Fertilization was the third most important parameter. FYM significantly increased yields compared to Control, but applied alone cannot cover the needs of potatoes. Similarly, the application of FYM and N increases yields, but for the highest yields, it is best to apply FYM + NPK (80 kg ha−1 N). Co-application of FYM and mineral N fertilizers mitigates the negative impact of mineral N on soil pH.

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 This paper presents the results of the statistical analysis of microbiological, physical and chemical parameters related to the quality of the water used in rice fields in Southern Brazil. Data were collected during three consecutive crop years, within structure of a comprehensive monitoring program. The indicators used were: potential hydrogen, electrical conductivity, turbidity, nitrogen, phosphorus, potassium, calcium, total and fecal coliforms. Principal Component and Discriminant Analysis showed consistent differences between the water irrigation and drainage, as the temporal variation demonstrated a clear reduction in the concentration of most of the variables analyzed. The pattern of this reduction is not the same in the two regions - that is, the importance of each of the different variables in the observed differentiation is modified in two locations. These results suggested that the variations in the water quality utilized for rice irrigation was influenced by certain specific aspects of each rice region in South Brazilian - such as anthropic action or soil/climate conditions in each hydrographic basin.

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.
