Abstract

An examination takes place to determine how defoliants, irrigation frequencies and fertilizer amounts affect S-8286 cotton development and yield specifically within Samarkand's meadow-gray soils of Uzbekistan. The field of defoliant optimization research exists independently from investigation into the regional connections between irrigation methods and fertilizer applications. Field experiments with randomized blocks contain two irrigation systems (65-65-60% and 70-70-60%) and mineral fertilizer amounts (N-250, P₂O₅-175, K₂O-125 kg/ha) evaluated UzDEF defoliant at 8.0 l/ha. A yield enhancement of 3.7 t/ha reached 38.6 t/ha occurred under the higher level of irrigation (70-70-60%) which resulted in better economic outcomes. Research showed that UzDEF application achieved both better defoliation effects and yield improvement without requiring additional expenditures. The profit margin reached 38.9% when farmers used ideal cultivation practices instead of the former 34.1% with less watering. The research establishes that combining water management with nutrient management creates ideal conditions to maximize cotton productivity while boosting economic results at the field scale. The experimental findings offer concrete guidelines to cotton growers about the proper use of scientifically supported defoliants which enhances production efficiency together with sustainable stewardship of the fields. Research should investigate how soil condition evolves after defoliant usage and how these changes affect fiber quality in the cotton crop.
