CULTIVATION OF THE CERASUS AVIUM CHERRY VARIETYIN THE KADAMJAY DISTRICT OF THE BATKEN REGION UNDER THE CONDITIONS OF CLIMATE CHANGE

Abstract

The purpose of the research was to analyze the agro-climatic indicators, which are the basis for the development and productivity of fruit crops in agriculture. The objectives of the research included: to present an updated analysis of agrometeorological conditions in the Kadamzhai district of the Batken region, to calculate the number and frequency of adverse meteorological phenomena that affect the yield of fruit crops. Objects and methods of research: the agrometeorological data of the Markaz agrometeorological station, the method of mathematical and statistical analysis were used. Results of the research: changes in agro-climatic indicators for the period 1991-2021 were clarified and revealed, a comparative analysis of abiotic factors was carried out: air temperature, precipitation, moisture coefficient. Trends were determined, numerical values were calculated, diagrams were built on the basis of updated data. Numerical values of deviations from long-term norms are calculated, regression analysis of data is performed, plots of diagrams are plotted on the basis of deviations in air temperature, precipitation and moisture coefficient, and their dependences are calculated. Deviations in the intra-annual distribution of air temperature, precipitation for the period 1991-2021, in comparison with long-term norms, have an uneven course. In some months, the numerical values of the deviations are significantly higher than the average values of the deviations, especially noticeable during the growing season. The calculated values confirm deviations from long-term temperature and precipitation norms on changes in the moisture coefficient, which confirms the impact of climate change in the area under consideration.
