This study investigates the effect of applying biostimulators in the cultivation of foreign and local cotton varieties on plant growth, development, and productivity. Cotton is one of the most important agricultural crops in Uzbekistan and many other cotton-producing countries, and the use of environmentally friendly technologies has become a priority in sustainable agriculture. The research examines both foreign and indigenous varieties under identical field conditions, comparing the physiological responses, morphological traits, and yield indicators when treated with biostimulators. Results demonstrated that biostimulators enhanced root and shoot development, improved photosynthetic activity, and increased boll formation, ultimately leading to higher productivity. Moreover, the study highlights the economic feasibility and ecological safety of biostimulator application in cotton production. These findings may serve as a basis for developing innovative agronomic practices aimed at increasing cotton yield and quality while reducing the need for chemical fertilizers and growth regulators.
