THE DEPENDENCE OF THE DISEASES PRESENCE AND PESTS ON NUTRIENT INORGANIC SOIL ELEMENTS

Abstract

The subject of the study is to assess the impact of different levels of nutrient deficiency in the soil on the physiological state and productivity of cherry and cherry trees in different districts of Osh and Batken oblasts of Kyrgyzstan. Research methods: to study the dependence of the presence of diseases and pests on the nutrient content of soil, field plots with different soil characteristics were used, analyzing humus, pH, total nitrogen, mobile phosphorus, exchangeable potassium and mechanical composition of soil. In the course of the research, the analysis of soil properties showed that the deficiency of elements contributes to increase the corresponding phytopathological changes in plants. The practical significance of the results obtained is that a comprehensive study of the inorganic element’s content in soil and symptoms of its deficiency allows the development of more effective fertilizer application strategies aimed at improving plant health and yields, which ultimately contributes to the stability and productivity of agriculture. Further, study is planned to compare more soil qualities with more cherry yields. Recommendations regular application of fertilizers in the necessary dosage contributes to the maintenance of the potassium balance and other elements in the system "soil-tree" and correlates with the improvement of yield and fruit quality.
