UZUMNING “KISHMISH QORA” NAVI HOSIL ELEMENTLARIGA MAKRO VA MIKROO‘G‘ITLAR HAMDA OʻSTIRUVCHI MODDALARNING TA’SIRI (URGUT TUMANI TIPIK BOʻZ TUPROQLARI SHAROITIDA)

In the typical sierozem regions of our republic, the viticulture sector is rapidly developing based on agro-climatic conditions and export potential. In particular, the “Kishmish Qora” grape variety, which has high export potential, requires the application of advanced agrotechnological approaches to improve quality and yield indicators. In recent years, it has been scientifically proven that the complex application of macro- and micronutrients, as well as growth regulators, has a significant positive effect on grape yield components. This study focuses on examining the effect of foliar application of macronutrients (NPK), micronutrients (copper, zinc, manganese) and gibberellin on the yield components of the “Kishmish Qora” variety, in particular, bunch weight, sugar accumulation, photosynthetic activity and overall yield under the typical sierozem soil conditions of Urgut district, Samarkand region. Based on the research results, modern, environmentally safe and economically efficient agrotechnological recommendations are being developed. The study offers a scientific and practical solution to urgent issues of introducing intensive technologies in the republic’s viticulture sector that comply with international standards, increasing export volumes and ensuring food security.
