In 2016-2019, research was conducted on the experimental field of the Ulyanovsk research Institute for the purpose of determining the effectiveness of starting doses of mineral fertilizers, as well as nitrogen fertilizing on the productivity and quality of winter wheat grain Marathon. Studies have established the optimal lead time of nitrogen fertilization and doses of mineral fertilizers. Weather conditions over the years of research were contrasting, which allowed us to assess the responsiveness of winter wheat to mineral fertilizers in conditions of different moisture availability. The most effective options were those with nitrogen fertilization at a dose of 34 kg/ha in the spring period on frozen soil, which allowed to obtain an additional 0.51 t/ha and, conversely, the lowest-in the autumn period (+0.16 t / ha). The maximum yield of winter wheat (3.72 t / ha) is formed during the seeding with the simultaneous introduction of 45.5 kg/ha of complex fertilizers in the rows against fractional application of ammonium nitrate in spring during tillering and booting of plants in the amount of 34 kg/ha and top dressing in the phase of earning with urea at a dose of 15 kg/ha. Correlation analysis showed a positive close relationship between the elements of the structure of the winter wheat crop depending on different doses and methods of applying mineral fertilizers and nitrogen fertilizers (r=0.82-0.96). The highest content of protein (on average 14.1%) and gluten (33.0%) was provided on the control background without use of ordinary fertilizers. The use of complex fertilizers during seeding resulted in a slight decrease of amount of protein (by 14%) and gluten (up to 32.4-32.9%). Nitrogen fertilizer had a greater impact on these indicators.

The research aim is to identify the most energy-saving and cost-effective technology for winter wheat cultivation. The maximum moisture content of soil was recorded when it was processed using Mini-till technology – from 17.2% to 17.9%, and the lowest - with traditional technology – from 15.7% to 16.4%. The lowest soil density with traditional winter wheat technology is both on the background with fertilizer (1.18%) and on the background without fertilizer (1.21%). The lowest contamination of crops with traditional technology without mineral fertilizers (42 pcs/м2). With the Mini-till technology, the total blockage increased to 51pcs/м2, and with the No-till technology, it was maximum- 128 pcs/м2. Against the mineral fertilizers, the same tendency of total blockage-from – from 40 pcs/м2 to 132 pcs/м2, respectively. With No-till technology, the total plant damage increased from 17.0 % to 14.6 %, with traditional treatment – from 12.4% to 10.1%, and with Mini-till technology-from 12.7% to 9.6%. The yield of winter wheat when using traditional plowing against the background of mineral fertilizer is 3.59 t / ha, and against the background without mineral fertilizer – 2.24 t / ha. The yield of Mini-till technology for mineral background is 3.13 t / ha, and without fertilizers-1.81 t / ha. With the No-till technology, the winter wheat yield is 1.69 t/ha, and without fertilizers – 1.11 t/ha. The highest level of profitability with Mini-till technology against the background of mineral fertilizers-73.2%.

Аim. Assessment of current climate changes in the territory of Ciscaucasia in order to predict the yield of winter wheat.Methods .Integral indicators of climatic conditions for agricultural production were employed. For the investigations, we selected five‐year periods for which the meteorological parameters were averaged, and to identify trends the data of specific five‐year periods were compared with the average value for the entireseries of observations (1960‐2020).Results. The deviation of precipitation in April was highest in 2011‐2015, when it increased by 22 mm, and in 1986‐1990 and 1991‐1995, when it decreased by 15 and 10 mm respectively. In Eastern Ciscaucasia,where conditions are more arid than in the Western and Central regions, in both the rise in air temperature and the amount of precipitation, especially in April and May, increased in the 21stcentury for the entire period of active vegetation.Conclusion.It was established that the value of the hydrothermal coefficient practically did not change during the 1960‐2020 period. In the late 1990s and early 2000s, there was an increase in productivity against the background of a relatively high level of annual precipitation and this stability is confirmed at the present time. There is a very close relationship between natural and climatic factors and the level of winter wheat yield.

Основным направлением повышения качества зерна является выведение новых сортов, генетически предрасположенных формировать зерно с высоким качеством. Вместе с тем, генетический потенциал сортов способен реализовываться только при конкретных погодных условиях и применении приемов возделывания, благоприятно влияющих на рост и развитие растений. В настоящих исследованиях путем изменения режимов питания растений создавали различные условия для того, чтобы определить возможности сортов формировать урожай зерна с большим содержанием белка. Цель работы оценить и выделить сорта озимой пшеницы, способные реализовать потенциал качества зерна при различных уровнях интенсификации минерального питания. Для достижения цели был заложен двухфакторный полевой опыт. Фактор А сорта озимой пшеницы, фактор В уровни минерального питания. В результате установлено, что сорта озимой пшеницы характеризуются неодинаковыми свойствами накапливать белок в зерне. Высокой активностью накапливать белок при внесении удобрений характеризуется сорт Клавдия 2. Средней активностью сорта Безенчукская 380, Московская 56 и низкой Немчиновская 57, Скипетр и Фатинья. Внесение минеральных удобрений из расчета N16 P16 K16 при посеве осенью и N68 в подкормку весной способствует формированию зерна с более высоким содержанием белка у всех сортов озимой пшеницы.The main direction of improving the quality of grain is the cultivation of new varieties genetically predisposed to form high quality grain. At the same time, the genetic potential of varieties can only be realized under specific weather conditions and the application of cultivation techniques that favourably affect the growth and development of plants. In these studies, various conditions were created by changing plant nutritional regimes in order to determine the possibilities of varieties to form a grain crop with a high protein content. The purpose of the work was to evaluate and highlight varieties of winter wheat that can realize the potential of grain quality at various levels of intensification of mineral nutrition. To achieve the goal, a two-factor field experiment was carried out. Factor A - winter wheat varieties, factor B - levels of mineral nutrition. As a result, it was established that varieties of winter wheat were characterized by unequal properties to accumulate protein in grain. Variety Claudia 2 was characterized by high activity to accumulate protein when fertilizing. Bezenchukskaya 380, Moskovskaya 56 were characterized by medium activity and Nemchinovskaya 57, Scepter and Fatigna - by low. The application of mineral fertilizers at the rate of N16 P16 K16 during sowing in fall and N68 for top dressing in spring contributed to the formation of grain with a higher protein content in all varieties of winter wheat.

Winter Wheat Yield

In Poland winter wheat is grown on the area of 1.600.000 ha. Most of the plant protection treatments are being done without thorough analysis of real threats from pests and diseases. The aim of the research is to develop the optimal program of wheat protection against pests and diseases based on integration of various methods of plant protection. Two programs: conventional and integrated were compared. In integrated program the eventual needs and terms of treatments were estimated on the basis of detailed observations of plant infection, pest appearance, their natural enemies and thorough analysis of weather conditions and forecasts. The role of disease resistant wheat varietes and nitrogen fertilizers was also analysed. The research took into account beneficial entomofauna and its influence on pest numbers as well as influence of chemicals used in agriculture on their species. As the result the selective pesticides, safe to beneficial organisms, were selected. The quantity and quality of winter wheat yield was analysed, including protein and gluten contents. The economic effectiveness of various programs of wheat protection against pests and diseases was assessed. The results of research are important both in practical and scientific sense.

Winter Wheat Yield

Information on crop yield at scales ranging from the field to the global level is imperative for farmers and decision makers. The current data sources to monitor crop yield, such as regional agriculture statistics, are often lacking in spatial and temporal resolution. Remotely sensed vegetation indices (VIs) such as NDVI are able to assess crop yield using empirical modelling strategies. Empirical NDVI-based crop yield models were evaluated by comparing the model performance with similar models used in different regions. The integral NDVI and the peak NDVI were weak predictors of winter wheat yield in northern Belgium. Winter wheat (Triticum aestivum) yield variability was better predicted by monthly precipitation during tillering and anthesis than by NDVI-derived yield proxies in the period from 2016 to 2018 (R2 = 0.66). The NDVI series were not sensitive enough to yield affecting weather conditions during important phenological stages such as tillering and anthesis and were weak predictors in empirical crop yield models. In conclusion, winter wheat yield modelling using NDVI-derived yield proxies as predictor variables is dependent on the environment.

The Impact

SummaryDrought reduces crop yields not only in areas of arid climate. The impact of droughts depends on the crop growth stage and soil properties. The frequency of droughts will increase due to climate change. It is important to determine the environmental variables that have the strongest effect on wheat yields in dry years. The effect of soil and weather on wheat yield was evaluated in 2018, which was considered a very dry year in Europe. The winter wheat yield data from 19 trial locations of the Research Center of Cultivar Testing (COBORU), Poland, were used. Soil data from the trial locations, mean air temperature (T) and precipitation (P) were considered as environmental factors, as well as the climatic water balance (CWB). The hydrothermal coefficient (HTC), which is based on P and T, was also used. The effect of these factors on winter wheat yield was related to the weather conditions at particular growth stages. The soil had a greater effect than the weather conditions. CWB, P, T and HTC showed a clear relationship with winter wheat yield. Soil data and HTC are the factors most recommended for models predicting crop yields. In the selection of drought-tolerant genotypes, the plants should be subjected to stress especially during the heading and grain filling growth stages.

Nitrogen Rates

Winter wheat is commonly cultivated in Ukraine. This crop has nutritional requirements that have been affected due to the climate changes that in the recent years the country has been suffered. In the spring season, the plant is found in growing stage, which requires a suitable nitrogen nutrition and it must be supplied due to the deficit of this element during the vegetative development. Within this framework, this study aimed to establish the optimal nitrogen rate for winter wheat that was applied in different configurations on leached black soil, and to determine the effectiveness of nitrogen application to the frozen soil surface in early spring as a basis for these fertilizations. The experiment was conducted at the Bila Tserkva ResearchSelection Station (Ukraine) during 2017–2019. The soil of this place corresponds to a leached loamy black soil (Mollisol) with content of organic matter between 3.6-3.8%, mobile phosphorus (P2O5) 156-166 mg kg-1, potassium (K2O) 64-77 mg kg-1, and pHKCl 5.8–6.3. A randomized experimental design with four nitrogen rates (0, 60, 80, 110 kg ha-1) with four replications as factorial arrangement was used. The results indicated that winter wheat yield was significantly affected by all nitrogen fertilizer rates (P<0.05). The highest average grain yield was obtained with 110 kg ha-1 nitrogen rate that combined application nitrogen to the frozen soil surface and the foliar feeding with 6.90 t ha-1. In years of regular precipitation during the growing season (2018-2019), nitrogen fertilizers had a more pronounced effect on winter wheat yield than in a year of precipitation deficiency (2017). A significant increase in grain protein content was obtained in variants where foliar feeding of winter wheat with urea solution was a part of fertilization strategy; it was attributed to nitrogen rates of 80 and 110 kg ha-1. The increase in protein content of the grain was less dependent on the weather conditions and was stable through the years of experiment.
