ECOLOGICAL SUSTAINABILITY AND ADAPTIVE POTENTIAL OF PEAR VARIETY ‘TALGARSKAYA KRASAVITSA’ UNDER AGROTECHNICAL APPROACHES

In the current conditions of the agricultural sector, improving the quality of fruit crops and optimizing agrotechnical cultivation methods are pressing tasks. This study investigates the ecological and biological characteristics of the pear variety “Talgarskaya Krasavitsa” grown in the botanical garden of Khoja Akhmet Yassawi International Kazakh-Turkish University (IKTU). The aim of the research is a comprehensive assessment of the impact of various agrotechnical methods on the growth, development, and productivity of this variety in order to enhance its economic efficiency. The study includes an analysis of domestic and international practices in pear cultivation, an examination of the morphological and physiological traits of the variety, and an evaluation of the impact of different agrotechnical methods on plant productivity. Field and laboratory methods were employed to assess biometric indicators, including spectrophotometric analysis of photosynthetic pigments, biometric measurements of trees, and fruit quality analysis. The research results demonstrated that the application of updated agrotechnical technologies, including additional fertilization and growth stimulants, contributed to increased productivity, enhanced fruit mass, and improved chemical composition. A strong positive correlation was established between trunk diameter and plant productivity (r ≈ 0.986), confirming the effectiveness of optimized agrotechnical practices. The scientific novelty of the study lies in the comprehensive analysis of the impact of various agrotechnical methods on the biometric and physiological parameters of the “Talgarskaya Krasavitsa” variety. The practical significance of the work is related to the development of recommendations for optimizing pear cultivation under continental climate conditions, which can be useful for farmers engaged in commercial horticulture and agronomists.
