The paper presents the analysis of meteorological criteria and the study of their influence on productivity of winter and spring grain crops through 20 years (1999–2018) in the Central zone of the Republic of Kalmykia. Meteorological information was analyzed differentially, i. e. for the entire period, over five-year terms (cycles), in separate years and seasons. The yield analysis was carried out according to the test results of 2170 variety samples of winter soft wheat, 334 samples of winter triticale and 503 spring barley varieties. Over the years the temperature was constantly becoming warmer. The average annual air temperature through 20 years exceeded the climatic norm on 1.30 °C (+10.7 °C). A similar situation took place both over five-year terms and in separate seasons. In winter the air temperature exceeded the norm by 1.7 °C (–2.5 °C), in the spring by +1.7 (+10.50 °C), in summer by +1.4 (+24.50 °C), in the autumn by +0.6 °C (+10.0 °C). In the important (summer) period of grain yield formation the amount of precipitation decreased by 25.6% (85.6 mm) of the climatic norm (115 mm). It was established that the main moisture accumulation (179.1 mm (55.1%) of precipitation) occurred in the autumn (25.8% (83.8 mm)) and in the spring (29.3% (95.3 mm)). Contrasting weather conditions made it possible to establish the effect of anomalous climatic parameters on productivity of winter wheat, winter triticale and spring barley. The results of productivity analysis through 2014–2018 showed that in the changed vegetation conditions winter soft wheat (3.19 t/ha), winter triticale (3.45 t/ha) and spring barley (2.53 t/ha) tended to increase average productivity by 0.34, 1.49 and 0.56 t/ha, respectively, compared with 1996–2000.

In the arid central zone of the Republic of Kalmykia, one of the limiting factors that affects spring barley productivity is the soil moisture content during a vegetation period. The paper discusses the results of a long-term research of zoned spring barley varieties of various breeding institutions in the experimental field of the KRIA named after M. B. Narmaeva, a branch of the FSBSI “PAFRC RAS” to study the effect of instability of soil moisture in a vegetation period on their productivity and especially in the period of grain filling. Field trials were carried out according to the Methods of State Variety Testing of agricultural crops and Methodology of a field trial. In the course of the studies it was found that in arid years the variety “Shchedry” formed a larger yield than that of other zoned varieties. Moreover, in the wet years of 2016 and 2017 the variety “Shchedry” productivity was inferior to the varieties “Prerii” and “Strannik” on average. It has been revealed that in conditions with uneven precipitation in different years, June precipitation has a decisive effect on spring barley productivity in the central zone of the Republic of Kalmykia.

The Impact

Исследования проводили в 2019 и 2020 годах на Полевой опытной станции РГАУ–МСХА им. К. А. Тимирязева. Целью исследований было изучение влияния регуляторов роста ретардантного типа различного химического состава, а также биоудобрений на продукционный процесс и урожайность ярового ячменя в условиях Центрального Нечерноземья. Результаты проведённых исследований показали, что яровой ячмень в разных метеорологических условиях вегетационного периода по-разному реагировал на совместную обработку биоудобрениями и регуляторами роста. В условиях недостатка влаги обработка растений регуляторами роста не оказывала влияния на высоту растений и снижала урожайность культуры по сравнению с необработанными растениями. Применение ретарданта «ХЭФК, ВР» на посевах ячменя вызывало максимальное снижение урожайности (от 0,82 до 1,52 т/га) независимо от вида применяемого биоудобрения. Существенное влияние на величину урожая в засушливых условиях оказывал препарат «Харди, Р». Причём использование его в чистом виде снижало урожайность ячменя на 0,9 т/га, тогда как при совместном применении препарата «Харди, Р» с биоудобрениями урожайность ячменя практически не изменялась. При благоприятных погодных условиях применение изучаемых морфорегуляторов совместно с биоудобрениями позволило получить существенную прибавку урожая. Использование на посевах ячменя ретарданта «РЭГГИ, ВРК» с удобрением «Биогор» позволило дополнительно получить 1,37 т/га. Обработка растений органоминеральным удобрением «Экофус» совместно с ретардантами «Харди, Р» и «РЭГГИ, ВК» повысила урожайность на 1,19 и 0,89 т/га соответственно. Повышение урожая ячменя при совместном применении ретардантов и биоудобрений в благоприятных погодных условиях обусловлено увеличением продуктивной кустистости растений и продолжительности работы листового аппарата. The investigation took place at the Field Research Station of the Russian Timiryazev State Agrarian University in 2019–2020. The aim was to test the effect of growth retardants and bio fertilizers on spring barley performance in the Central Non-Chernozem region. The effectiveness of bio fertilizers and retardants was greatly affected by weather conditions. Under water deficit growth regulators showed no effect on plant height but decreased crop productivity. The retardant “KHEFK, VR” provided the lowest yield (from 0.82 to 1.52 t ha-1) regardless of fertilizer type. The preparation “Khardi, R” significantly affected barley yield under drought. Its application led to the yield decrease by 0.9 t ha-1, while in combination with biofertilizers it had practically no effect on barley productivity. Combination of retardants and bio fertilizers significantly improved barley yield under favorable conditions. The retardant “REGGI, VRK” combined with the fertilizer “Biogor” provided the yield increase of 1.37 t ha-1. Application of the fertilizer “Ekofus” together with the retardants “Khardi, R” and “REGGI, VRK” improved barley productivity by 1.19 and 0.89 t ha-1, respectively. Combined application of retardants and fertilizers resulted in more active tillering and longer photosynthetic activity of leaves leading to higher plant productivity under favorable conditions.

Проведено сравнение урожайности озимой пшеницы и ярового ячменя при многолетнем возделывании по технологиям традиционной и ресурсосберегающей обработки в четырёхпольном зернопропашном севообороте на дерновоподзолистой почве. Предшественником в севообороте для пшеницы была викоовсяная смесь, для ячменя картофель. Традиционная обработка как под пшеницу, так и под ячмень включала дискование стерни после предшественника, отвальную вспашку на 22 24 см и предпосевную культивацию. Альтернативными методами обработки почвы являлись: под ячмень минимальная обработка дисковым культиватором на 12 14 см, под пшеницу нулевая обработка, прямой посев с предварительной обработкой поля гербицидом на основе д.в. глифосата. Пшеницу удобряли по схеме: N32P32K32 перед посевом и две подкормки N70 в течение вегетации. За 11 лет исследований средняя урожайность озимой пшеницы на фоне интенсивного применения удобрений в варианте традиционной обработки 5,00 т/га, в варианте нулевой обработки 4,84 т/га (при НСР05 0,56 т/га). За тот же период урожайность ячменя на фоне N40P40K40 составила в варианте традиционной обработки 3,83 т/га, при минимальной 3,91 т/га (при НСР05 0,19). В отдельные годы урожайность озимой пшеницы и ячменя была существенно выше в варианте традиционной вспашки по сравнению с ресурсосберегающей обработкой, в другие годы наоборот, но постоянной тенденции преимущества одной из двух изучаемых технологий выявлено не было. Таким образом, способы обработки почвы традиционная вспашка и ресурсосберегающая обработка, минимальная или нулевая не оказывают постоянного, воспроизводимого из года в год положительного или отрицательного воздействия на урожайность зерновых. За 11летний период наблюдений было выявлено, что на фоне применения рекомендованных доз минеральных удобрений урожайность зерновых в большей степени зависела от метеоусловий вегетационного сезона, нежели от способа обработки почвы. The investigation included the competitive trial of winter wheat and spring barley under conventional and resourcesaving cultivation. The crop rotation was performed on sodpodzolic soil for 4 years. Vetchoat mixture preceded wheat while potato barley. Conventional tillage included disk plowing after the forecrops, 22 24 cm moldboard plowing and seedbed preparation. Alternatively, 12 14 cm disk plowing, zero tillage and direct seeding were used under glyphosatebased herbicide application. Wheat grew on the background of N32P32K32 and obtained N70 twice during its growing season. For 11 years wheat productivity averaged to 5.00 t ha1 under conventional cultivation and 4.84 t ha1 under zero tillage (LSD 0.56 t ha1, P 0.05). Barley yielded 3.83 t grain ha1 under conventional cultivation and 3.91 t grain ha1 under minimum tillage (LSD 0.19, P 0.05) on the background of N40P40K40. In some years wheat and barley performed better under conventional cultivation but the data was inconsistent. Therefore, tillage type had no constant positive effect on crop productivity. Crop productivities were mostly affected by weather conditions when applying the recommended fertilizer rates.

Direct Sowing

The effects of traditional tillage cultivation (control treatment), no tillage (instead of tillage the soil was loosened with scruff), and direct sowing (with a special drill into unploughed soil) on the health of spring barley cultivar. Klimek were compared in three-field crop rotation (field bean, winter wheat, spring barley) in an experiment performed in the years 1997-1999 on the soil of a good wheat complex. The results of phytopathological observations carried out over the vegetation season are presented in the form of an injury index. The following diseases were recorded on spring barley: net blotch (<i>Drechslera teres</i>) - net type and spot type, powdery mildew (<i>Blumeria graminis</i>), leaf blotch (<i>Rhynchosporium secalis</i>), eyespot (<i>Tapesia yallundae</i>) and foot rot (fungal complex). Tillage system had no a significant influence on the occurrence of both types of net blotch. The intensity of powdery mildew and leaf blotch was the highest in the case of traditional tillage cultivation, and the lowest - in that of no tillage. Direct sowing was conductive to the development of eyespot, and no tillage - to foot rot. Fungi of the genus <i>Fusarium</i>, mainly <i>F. culmorum</i>, and the species <i>Bipolaris sorokiniana</i>, were isolated most frequently from infested stem bases. The weather conditions differed during spring barley grown in the three years analyzed. Mean air temperature in 1997 and 1998 was similar to the many-year average for the city of Olsztyn and its surroundings (13.8<sup>°</sup>C). In the vegetation season 1999 mean air temperature reached 14.6<sup>°</sup>C, and was considerably higher than the many-year average. Taking into account total precipitation and distribution in the three-year experimental cycle, 1997 and 1998 can be considered average, and 1999 - wet.The weather conditions had a significant effect on the intensity of all diseases observed on spring barley. The highest yield grain was obtained in the case of traditional tillage cultivation (on average 3.06 t·ha<sup>-1</sup> for the three years analyzed), and the lowest - in that of direct sowing (2.18 t·ha<sup>-1</sup>). No tillage occupied a middle position (2.55 t·ha<sup>-1</sup>).

Methodological Guidelines

The results of the research (2016–2018) into variability of characteristics of spring barley with the purpose of obtaining the most resistant varieties are presented. The study was conducted in the crop rotation in the breeding nursery of competitive variety testing in the forest-steppe zone of the Republic of Tuva. It was preceded by bare fallow and repeated four times. The soil was dark chestnut, light loamy. The area of the plot registered for the study was 28 m2. Testing, phenological observations, crop records and data processing were carried out in accordance with the approved methodological guidelines. The weather conditions for moisture availability and the average daily temperature regime during the study period varied signifi cantly:  in 2016, 2018, which was excessively wet, HTC (hydrothermal coeffcient) was 1.65, 1.90, in moderately humid 2017 HTC equaled 1.36. This made it possible to reliably identify more adapted biotypes of spring barley. In the Republic of Tuva, the yield of spring barley largely depends on the adaptive properties of cultivated varieties and the implementation of the main parameters of the yield structure: the number of productive stems, pieces/m2 (r = 0.726 ± 0.01 ... 0.960 ± 0.266); the mass of 1000 grains, g (r = 0.648 ± 0.179 ... 0.883 ± 0.245). An increase in the number of grains in an ear negatively affects crop yields (r = 0.212 ± 0.058 ... – 0.457 ± 0.126). From the samples of spring barley of Siberian breeding work that were studied in the research, the following samples were identifi ed for further breeding for productivity (L 19-101, U 50-3808, U 49-3795); a large number of productive stems (Acha, L 19-101, U 49-3795, U 50-3808); high mass of 1000 grains (Acha, L 19-101, U 50-3808, U 49-3795). These varieties should be included in the cross-breeding adaptive program on the territory of the Republic of Tuva.

The Impact

Analysis of changes in hydrothermal conditions of growing crops in the forest steppe zone of Ukraine over a period of 2004–2016 showed that by the average monthly air temperature more than a half of the years under study and by rainfall nearly a third of the researched period differed significantly from the average long-term value and were close to extreme weather. Statistical analysis of long-term indicators of the air temperature regime is evidence of a steady trend towards an increase in average annual air temperature with significant fluctuations in indices in separate periods from 7.9 ± 2.9 to 10.0 ± 2.5oС and a decrease in the amount and instability of natural moisture entry. The influence of weather conditions on the formation of productivity of spiked cereals (winter and spring wheat, spring barley) and maize was assessed at the current agrometeorological risks in the forest steppe of Ukraine. Based on the correlation-regression analysis, mathematical models were created that reproduce the dependence of grain yields upon the complex weather conditions of the growing season, the impact of which reached 60–70%. The conditions of eight years (2006–2008, 2011–2014 and 2016), when the hydrothermal index for the vegetation period was 1.13–1.76, turned out to be optimal by hydrothermal indicators to harvest maize yield at 5.83–9.47 t/ha. However, the years of 2005, 2009–2010 and 2015 were unfavorable as they received precipitation by 120 mm lower than a norm or 36% of the norm. The rainfall by 37–61% lower than a norm in June–July and grain yield 3.12–6.51 t/ha were also characteristic of the years mentioned above.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

Result of research in different years of water availability among the rooms was allocated a group of high-protein barley with improved feed value: 4 varieties, 2 of which are on the state variety testing, and 2 promising lines. The range of variation of protein content in the grain of the selected samples varied from 13.1 to 14.5 %, lysine – from 0.48 to 0.52 %, weight of 1000 grains-from 48.0 to 53.5 g. According to the data obtained the highest value of protein in grain was observed in krupnosortnogo varieties Zlatoyar (GSI), amounting on average for 14.5 %. The increase was equal to 1.1% in relation to the control variety Yaromir. With an average yield of 6.52 t/ha in the years of research grade Accounting have provided protein per hectare in the amount of 0,94 t/ha. A new variety Sudar´ (GSI) and breeding line 149/4-12 h 788 and 129/1-14 h 907 this indicator has been less productive, however, exceeded the grade Yaromir 0.10 to 0.16 t/ha. Given the higher productivity of new promising varieties and breeding lines, the collection of lysine per unit area they have 12.7, 30.8 per cent was higher than that of the Promej class and 10.6-23.6% more than in the variety Yaromir, which indicates their high biological value. Selected hulless line 1137 h is also an encouraging source of protein and other nutrients of plant origin. The selected lines and new varieties, regardless of weather conditions, were able to ensure the production of high-protein and sources' grain for feed purposes, while maintaining productivity.
