Wheat is one of the most important staple foods in temperate regions and is in increasing demand in urbanizing and industrializing countries such as China. Enhancing yield potential to meet the population explosion around the world and maintaining grain quality in wheat plants under climate change are crucial for food security and human nutrition. Global warming resulting from greenhouse effect has led to more frequent occurrence of extreme climatic events. Elevated atmospheric CO2 concentration (eCO2) along with rising temperature has a huge impact on ecosystems, agriculture and human health. There are numerous studies investigating the eCO2 and heatwaves effects on wheat growth and productivity, and the mechanisms behind. This review outlines the state-of-the-art knowledge regarding the effects of eCO2 and heat stress, individually and combined, on grain yield and grain quality in wheat crop. Strategies to enhance the resilience of wheat to future warmer and CO2-enriched environment are discussed.

The article investigates the influence of the application of different systems of basic tillage on the quality of winter wheat grain in short crop rotations of the Southern Steppe of Ukraine. It is established that the grain quality of winter wheat in the Southern Steppe of Ukraine is mainly determined by the genetic characteristics of the variety, but also largely depends on the conditions and technologies of cultivation. In winter wheat grain, which is used for food purposes, reserve proteins are important, which in winter wheat determine the baking properties of flour. In drought conditions, when the yield of winter wheat decreases, the protein content in its grain tends to increase. In wet years, on the contrary, there is a reverse pattern. According to experimental studies, wheat varieties have a negative correlation between grain protein content and yield. It is established that during 2016–2020 research shows almost the same pattern of action of different predecessors and systems of basic tillage on the formation of grain quality of winter wheat in arid conditions. It was found that, on average, according to all variants of research, only with the use of the system of tillage-free tillage received grain of winter wheat with a protein content of 12,5%, which met the requirements of the 2nd class. It is recorded that on average over five years of research on all tillage systems, grain of winter wheat with gluten content was obtained, the quality of which corresponded to the 3rd class. Different tillage systems caused a slight impact on the gluten content, which ranged from 20,6% to 21,1%. It is determined that the precursors have a certain effect on the protein content in the grain of winter wheat. The analysis of qualitative indicators showed that on average in five years of research, when growing winter wheat after a pair of black and a pair of green wheat with winter vetch, grain was formed, which in terms of protein content corresponded to the 2nd quality class. More protein was accumulated in winter wheat grain after a pair of black, which was 12,9%. After peas for grain, as well as a pair of green with a mixture of white mustard and peas, received a grain of winter wheat, which was the 3rd quality class. It was found that on average in five years of research, all variants of winter wheat were grown with gluten content, which met the requirements of the 3rd class. Black vapor and green vapor with winter veneer caused the accumulation of gluten at almost the same level with a small increase in the version with winter vetch up to 21,8%. The lowest level of gluten was obtained in the grain of winter wheat after peas per grain, which was 19,7%. In all variants of the experiment, sidereal steam with winter tillage and the use of tillage-free tillage had the best effect on the growth of winter wheat grain quality indicators. The grain of winter wheat was mainly formed in terms of quality, which allows it to be used for food purposes – mainly in the flour-milling and baking industries, as well as for export. It is established that it is important to further study the quality of winter wheat grain and other cereals in short crop rotations of the arid Southern Steppe of Ukraine, especially in climate change.

This study evaluated how organic manures and mineral fertilizers affect winter wheat grain and straw yields and grain quality properties. The analysed period of the long-term fertilizer experiment was established in Čáslav, Czech Republic, in 1955 and covers the seasons 2011–2014. The fertilizer treatments were: control; farmyard manure (FYM); FYM + P; FYM + K; FYM + PK; FYM + N<sub>1</sub>; FYM + N<sub>2</sub>; FYM + N<sub>1</sub>PK; FYM + N<sub>2</sub>PK and FYM + N<sub>3</sub>PK. The highest grain yields were recorded in the FYM + P and FYM + N<sub>3</sub>PK treatments (8.9 t/ha). The highest straw yields were recorded in the FYM + N<sub>3</sub>PK treatment (6.52 t/ha). The lowest yields were provided in the unfertilized control and FYM treatments. Qualitative parameters were evaluated in the control, FYM and FYM + N<sub>3</sub>PK treatments between the years 2011 and 2013. The best quality of wheat grain was provided by the FYM + N<sub>3</sub>PK treatment. Combination of the farmyard manure with NPK is the best way to achieve high grain yields with good quality and leads to sustainable food production.
