“…N.E. Samofalova et al (2019) prove that the temperature regime plays a crucial role in the yield of winter durum wheat, and its productivity depends not on the total amount of precipitation, but on their distribution, the presence of moisture in the soil, and temperature. However, these studies were conducted in different soil and climatic conditions, which differ from the southern steppe of Ukraine.…”

Despite the high genetic potential of productivity of new varieties, the yield of durum winter wheat remains low. One of the reasons for this is non-compliance with the recommended cultivation technologies, which would take into account the genetic characteristics of different varieties, their adaptation to the climatic conditions of the region. Due to insufficient scientific studies of the impact of weather conditions on the productivity of durum winter wheat, taking into account the main strategy of agricultural adaptation to negative climate changes in the southern steppe of Ukraine, the research topic is relevant. The aim of the work was to determine the degree of influence of changes in weather and climatic conditions in the main interphase periods on the growth and development and yield of winter durum wheat grain, depending on the varietal composition. Field studies were conducted during 2014-2020 years in the experimental field of the MNAU training, research and practical center with four varieties of winter durum wheat. In the course of the study, generally accepted methods were used: system approach and systems analysis, monographic, analysis and synthesis, field research and statistical mathematical, etc. Its predecessor was black steam, the sowing period was October 1st. According to the results of research, it was determined that the formation of winter durum wheat grain yield was significantly influenced by the duration of interphase and vegetations and the amount of precipitation. The weather conditions of 2014, 2016 and 2019 were more favorable for the germination of winter durum wheat seeds, when the plants reached the sum of effective temperatures of 70.0-89.1 ° С, the duration of the interphase period "sowing-seedlings" was only 11-12 days. In favorable yields in 2016 and 2019 years the duration of the vegetation of plants was the longest – 296 and 288 days, respectively, with the amount of precipitation for the reporting period – 358.5-402.0 mm, and in unfavorable years in 2018 and 2020 years the vegetation was 272 and 276 days with the amount of precipitation 256.9 and 308.9 mm. The highest average yield of winter durum wheat grain by variety was formed in 2016 year as 7.24 t/ha, which was by 8.3-43.5% higher than in other years studied

“…Climatic and weather conditions have a significant impact on agricultural production since they largely determine the level of crop yields, product quality, production costs, and features of agrotechnical and technological measures [1,2]. The main factors of crop productivity also include the application of fertilizers, the use of plant protection products, and the implementation of appropriate tillage practices [3].…”

Current trends in climate change associated with the growth of heat supply contribute to the growth of bioclimatic potential and the increase in productivity of grain crops in the North-West of Russia. In such conditions, research is relevant aimed at clarifying the contribution of weather conditions and anthropogenic activity in the formation of the crop. The research was conducted on the crops of winter rye, spring barley, winter wheat, and spring wheat of the experimental landfill of the Menkovsky branch of the Agrophysical Research Institute. We studied various factors of anthropogenic activity, such as the level of mineral or nitrogen nutrition, an integrated plant protection system, seeding rates, and the size of seed material. Variance analysis was used in statistical processing. According to the results obtained, weather conditions were the most significant factor of productivity for winter cereals, and mineral nutrition was crucial for spring crops. The integrated protection system was less important than both the weather conditions of the growing season and the background of mineral nutrition of cultivated plants. This factor appeared to be the least significant for winter rye, which often has a favorable phytosanitary situation. The novelty of the data obtained lies in determining the predominant value in varying the yield of nitrogen fertilizers and herbicide treatment for spring wheat. A little less critical were the seeding rate and the size of the seed material.

“…Therefore, in recent years, the farmers have paid great attention to improvement of the adaptability level of the new developing varieties. The analysis of this trait gave an opportunity to predict the variety response to unfavorable environmental conditions, which allowed realizing their potential productivity [4,5]. According to the above mentioned concept, the current winter barley breeding is aimed at developing the varieties with the improved adaptability, high and stable productivity with low energy and resource costs [6,7].…”

There has been estimated the ecological adaptability and stability of winter barley varieties in the conditions of the Rostov region. There were studied 4 varieties and 6 lines of winter barley developed in the FSBSI “Agricultural Research Center “Donskoy”. The estimation was conducted according to the S.A. Eberchart, W.A. Rassel method (1966, ed. by V.A. Zykin), using a statistical processing software Statistica 10 and Excel. During the years of study (2017-2019), the environmental conditions varied significantly, which allowed reliably estimating the environmental adaptability and stability of the studied varieties and lines. The analysis of adaptability and stability resulted in identification of such responsive varieties as ‘Marusya’ and ‘Yerema’, as well as the line ‘Parallelum 1976’ with linear regression coefficients more than 1. The varieties ‘Marusya’ and ‘Yerema’ were the best ones among the studied varieties and lines, showing high and stable productivity over the years of study. According to the study results the variety ‘Vivat’ showed a sufficiently high level of adaptability. The variety ‘Timofey’ and the lines ‘Parallelum 1979’, ‘Parallelum 1981’, ‘Pallidum 1972’ showed a sufficiently high level of stability.
