ANALYSIS OF THE INFLUENCE OF METEOROLOGICAL CONDITIONS ON THE PRODUCTIVITY OF SPRING WHEAT IN 2023 AT THE TAIYNSHA WEATHER STATION OF THE NORTH KAZAKHSTAN REGION

Abstract

According to the results of the assessment about possible agricultural losses due to climate change, conducted as part of the preparation of the Seventh National Communication of the Republic of Kazakhstan on Climate Change, including for the North Kazakhstan region, where, according to the forecast, by 2050 a decrease in moisture supply during the growing season by 11…16 % and an increase in climate aridity by 10…15 % relative to current indicators are expected. As a result of such changes, this may lead to a decrease in the yield of spring wheat by 30…40 %. The aim of this study was to establish the relationship between the yield of Aviada spring wheat and meteorological conditions at the observation site of the Taiynsha meteorological station in the North Kazakhstan region for 2023. For this purpose, the actual meteorological parameters for the specified year were studied, such as temperature and precipitation, hydrothermal moisture coefficient (HTC), productive moisture reserves in the soil, sums of effective temperatures, as well as the growth and development characteristics of spring wheat of the Aviada variety during the vegetation period of 2023, its yield.It was found that insufficient precipitation during the critical phases of spring wheat development created stressful conditions during the grain ripening period, and, as a result, affected its yield. In addition, the shift of summer precipitation to August…September led to crop losses during and after harvesting. This article represents the results of the research internship that took place at Taiynsha meteorological station from May to August 2023.
