“…Температура воздуха повышается во все месяцы, однако, наиболее значимы в холодное время года, что в свою очередь приводит к увеличению продолжительности и засушливости теплого периода. Нейтрализующим фактором роста данного фактора является экономное использование водных ресурсов [13,14].…”

The article discusses the main approaches to increasing the volume of grain production and maximizing the use of bioclimatic potential in changing climatic conditions, and studying comprehensive assessments of the factors of potential and actually possible production by crops. The initial information for the research was the data of surface meteorological observations from 1990 to 2019 at six meteorological stations located on the territory of the Ulyanovsk region. In assessing long-term changes in agrometeorological parameters, Fourier expansion was used, and the parameters of the best sinusoidal approximation of the maximum and minimum points were determined. It was revealed that over the past three decades, there has been a steady increase in the average annual temperature (5.2 ° C), especially in the cold season. Moisture supply is more chaotic, the change is heterogeneous, varying from 280 mm (2012) to 664 mm (2017) and the average value for 1990-2019 is 498 mm. Barley (8.3 t/ha) has the greatest potential among grain crops in terms of photosynthetically active radiation (PAR), rye has the smallest (6.4 t/ha). In terms of the amount of thermal resources and moisture, rye reaches the maximum crop production, winter wheat is sensitive to moisture, and barley to temperature conditions. Moisture resources are the limiting factor in agricultural production, and therefore the level of use of bioclimatic potential varies from 19 to 29% in PAR, from 25 to 44% in moisture resources, and from 32.8 to 66% in thermal regime. Therefore, among the priority problems associated with adaptation work is analytical and practical activities in the field of assessment and analysis of the transformation of agriculture, ensuring its sustainability for adaptation to modern changes in climatic conditions. To adapt to modern changes in climatic conditions, it is necessary to improve the structure of sown areas, the use of effective fertilizers, technical equipment, the use of elite seeds, modern technologies. The scientific novelty of the research lies in the objective function of the bioclimatic potential of development against the background of global warming, the consideration of the system of potentials for the agricultural development of the region. The work is of practical importance, since the assessments being developed are a necessary tool in ensuring the target orientation of a unified regional policy in relation to the formation and use of development potential, including contributing to the formation of an idea of the real and potential opportunities of the region.

The aim of the research is to establish a possible change in the temperature regime of recent years (2016-2020) as compared to the long-term average annual values of the Izhevsk weather station and the assessment of the effect of this change on the specific features of crop production practices in the Middle Cis-Urals. Statistical method, comparison and analysis were used during the research. It has been established, that in the Middle Cis-Urals for the recent five years the warming has been recorded: the sum of temperatures higher than +10 оС has increased by 70 оС on the average and reached 2138 оС that provides growing the varieties of early-ripening and mid-season spring cereals. Every vegetation period is characterized by its own specific features, positive and negative deviations from the long-term average annual values both over the whole period and during some of its intervals. The rise in the sum of temperatures resulted in the 4 days earlier transition of the average daily temperature in spring over +5 оС , in autumn it led to 2 days later transition, that made the vegetation period by 6 days longer. It provides an earlier vegetative renewal in spring and a later stop in vegetation of winter crops as well as the possibility of an earlier start of field work with spring crops in spring. The calculations have proved that between the grain yield of spring wheat varieties and the hydrothermal coefficient (HTC) indicator there are different kinds of correlative relationships – neutral, average and strong positive ones. However, between the average yield of spring wheat grain on the farms of all categories in the Udmurt Republic and HTC, a strong positive correlative relationship (r = +0.73) has been established.
