“…Research by B.V. Blyznyuk et al [20] it was determined that the duration of the growing season as an important biological feature of winter wheat depends on both the genotype and the growing conditions of the variety. During the growing season, plants go through the corresponding phases of development associated with the formation of new organs.…”

The autumn growth and development of plants depend on a complex of external factors: the average daily air temperature, the amount of precipitation, the humidity of the seed layer of the soil, nutrients, light, etc. If winter wheat is sown at a later date, there are risks that the plants will enter the winter not well developed. It is possible to accelerate the passage of interphase periods with the help of irrigation, which is a necessary agrotechnical measure in the Southern Steppe of Ukraine. The purpose of the research is to establish the influence of varietal characteristics, irrigation and weather conditions on the duration of interphase periods of winter wheat in the autumn period on an international scale. Experimental research was carried out during 2020-2021 on southern chernozem, on the basis of the Educational Scientific and Practical Center of the Mykolaiv NAU with two varieties of winter wheat. Field, laboratory and comparative calculation methods were used during the research. The establishment and conduct of experiments were carried out according to the methodology of the research case. Soil moisture was determined by the thermogravimetric method, and phenophases were determined simultaneously throughout the experiment. It was determined that irrigation for 1-2 days reduces the duration of the interphase period of BBCH 00-09; for 3 days – BBCH 10-12; for 11 days – BBCH 13-19; for 5-7 days – BBCH 20-22. In natural conditions (without irrigation), the duration of the interphase periods (from BBCH 00-09 to 20-22) of the growth and development of plants of the studied varieties of winter wheat in 2020 was 93-96 days, which is 23-25 days more than in 2021. In plants of the Ovid variety under conditions of natural moisture (without irrigation), the interphase periods came 1-3 days later than in the Duma Odeska variety, while under irrigation conditions there was no significant difference. The obtained scientific results of the research will contribute to the wider implementation of irrigation, which will ensure the rapid and full growth and development of winter wheat plants in the autumn period, which will further contribute to increasing the yield and gross harvest of grain

“…B. Bliznyuk et al (2019) described how sowing dates in various soil-climatic zones differ and significantly depend on weather conditions, soil moisture reserves, predecessors, and other factors. Only by sowing at optimal dates is it possible to achieve high grain yield and corresponding quality.…”

Modern varieties of winter wheat have high genetic productivity potential that can be realised through improved cultivation techniques, including sowing dates optimisation, fertiliser system optimisation, and the application of microelements, which determines the relevance of this study. The purpose of the study is to substantiate the specific features of winter wheat productivity formation based on cultivation techniques in the Carpathian region. The research utilised field, laboratory (for grain quality determination), and statistical methods (for data reliability assessment). Field studies were conducted during 2021-2022 on grey forest surface-eroded soils. The growth and development characteristics of the Estafeta Myronivska, Dovira Odeska, and Akhim winter wheat varieties sown at different dates (September 20, October 5, October 20) were investigated. It was found that grain yield and individual productivity indicators of the studied winter wheat varieties varied depending on sowing dates, mineral fertilizer doses, foliar feeding, and varietal traits. The highest individual plant productivity indicators were achieved by the Estafeta Myronivska, Dovira Odeska, and Akhim varieties sown on October 5 with mineral fertiliser application N120P90K90 (including N30P90K90 applied during cultivation, N15 after soil thawing, N45 (in the BBCH 29-30 growth stage), N30 (BBCH 55-57) with dual application of micronutrients (Aidamin-complex foliar feeding). As a result of the studied factors, an increase in the number of productive stems, grains per stem, and grain weight per spike was observed. The highest grain yield among the studied varieties was achieved by the Estafeta Myronivska variety (5.65 t/ha) when sown on October 5 with N120P90K90 and Aidamin-complex foliar feeding. The research results can be used to adjust the cultivation techniques of winter wheat in production conditions to increase yield and grain quality

“…It is noted that one of the most effective options for solving the problem of drought resistance is the creation of new varieties of wheat adapted to drought (Itam et al, 2020;Chowdhury et al, 2021;Ahmad et al, 2022). Considering climate changes (Blyzniuk et al, 2019), breeding for increased resistance to drought and heat is a promising direction for further increasing wheat productivity (Collins & Chenu, 2021).…”

Wheat is one of the most important crops and the basis of human food and food security. Significant climate changes in recent years directly affect the formation of the level of wheat productivity. Therefore, the creation of varieties with increased resistance to drought at the initial stages of organogenesis, as well as the ability to form a high level of productivity in arid conditions is an urgent task in the modern selection of crops. The research aims to evaluate the level of drought tolerance wheat varieties different methods and to identify sources for involvement in crossbreeding during the selection of drought tolerance. Laboratory and field methods were used to study the researched varieties in response to drought: germination of seeds in a sucrose solution and determination of drought resistance indices by yield level. Varieties of spring wheat of different ecological and geographical origins have an increased productive potential in the conditions of the central part of the Forest Steppe of Ukraine. A wide range of variability in the degree of drought sensitivity of spring wheat was established. Varieties that have increased resistance to drought and can form a sufficient level of productivity under stress factors have been identified: Leguan (Czech Republic) and Koksa (Poland). The obtained results prove the possibility of combining in one variety an increased level of drought resistance and yield by classical breeding methods. According to the correlation coefficient between the productivity index and other studied indices of drought resistance, the effectiveness of using the Geometric Mean (proportional average) Productivity (GMP), Stress Tolerance Index (STI) and Yield Stability Index (YSI) indices in further breeding practice was noted. The practical research significance is determined by the combination of different methods for determining drought tolerance in crop breeding allowing for an objective assessment of resistance to stress factors and determination of viability at the initial stage of plant growth and development under the influence of the limiting factor – moisture
