“…As evidenced by Altieri and Nicholls [84] and Liu et al [149], applying sufficient amounts of organic matter into soils is critical when confronting adverse climatic impacts on wheat yield. It is notorious that in the short run, fertilizer application boosts yield [150][151][152]. Still, over a long-term horizon, we see a correlation between the volume of introduced mineral and organic fertilizers and the depletion of humus content in soils (from 40.2% at Stage III to only 10.8% at Stage IV).…”

Progressing climate change has been increasingly threatening the agricultural sector by compromising the resilience of ecosystems and endangering food security worldwide. Altering patterns of major climatic parameters require the perspectives of agricultural production to be assessed in a holistic way to understand the interactions of climatic and non-climatic factors on crop yield. However, it is difficult to distinguish the direct influence of changing temperature and precipitation on the productivity of crops while simultaneously capturing other contributing factors, such as spatial allocation of agricultural lands, economic conditions of land use, and soil fertility. Wide temporal and spatial fluctuations of climatic impacts substantially complicate the task. In the case of the 170-year retrospective analysis of the winter wheat sector in the south of Russia, this study tackles the challenge by establishing the multiplicative function to estimate crop yields as a long-term result of a combined influence of agricultural output parameters, qualities of soils, and climate variables. It is found that within the climate–land–yield triangle, linkages tighten or weaken depending on the strength of noise effects of economic and social perturbations. Still, the overall pressure of climate change on the cultivation of winter wheat has been aggravating. The inter-territory relocation of areas under crops based on the matching of soil types, precipitation, air temperature, and erodibility of lands is suggested as a climate response option. The approach can be employed as a decision support tool when developing territory-specific land management policies to cope with adverse climate impacts on the winter wheat sector.

Wheat is the main agricultural crop in many countries of the world, as well as the main food in the steppe zone, so the system of agrotechnical measures should be aimed at creating favourable conditions for obtaining a high yield. The issue of intensification of grain production is inseparable from the production and use of new biogenic effective drugs that have a positive effect on the growth and development of cultivated plants. The purpose of this study was to establish the effect of foliar fertilisation with bacterial preparations, precursors, and doses of mineral fertilisers on grain yield and productivity elements of winter wheat. The paper provides data on the results of the research of winter wheat of the Duma Odeska variety in the conditions of the Educational and Practical Centre of the Mykolaiv NAU in 2019–2021. During the study, generally accepted methods were used: monographic, systematic approach and systematic analysis, analysis and synthesis, field and statistical. The influence of the precursor, foliar feeding with modern bacterial biopreparations and the use of different doses of mineral fertilisers on the elements of the crop structure and grain yield of winter wheat was analysed. It was established that the yield level depended and changed on the precursor taken for foliar feeding of the bacterial preparation, the level of mineral nutrition and to a large extent on the influence of the weather conditions of the growing year. Over the years of research, precursors, mineral fertilisers, and treatment of plant sowing with biological preparations affected the number of productive stems, the number of grains from an ear, the mass of grain from one ear and the mass of 1,000 grains of winter wheat. The conducted studies confirmed the expediency of foliar fertilising in the main periods of vegetation with biological preparations to optimise the nutrition of winter wheat plants with the aim of forming a stable grain yield. The obtained scientific results of the research will contribute to the wide application of biological preparations, which will ensure the rapid and full growth and development of winter wheat plants, which will further contribute to increasing the yield and gross harvest of grain.
