This research describes positive effects of the combined use of stimulant + insecticide + fungicide in improving phytosanitary conditions of the cotton field. The upland cotton (Gossypium hirsutum L.) crop acquired proper nourishment with robust stems, numerous leaves, and enhanced photosynthesis productivity and resulted in the highest seed cotton yield with better fiber quality. By analyzing the cotton leaf surface area, fine fiber cultivar Marvarid provided 4,375,200 cm²/ha, followed by medium fiber cultivar Bukhara-8 with 4,262,700 cm²/ha, using the combination of stimulant + insecticide + fungicide. By analyzing the seed cotton yield, the fine-fiber cultivar Marvarid resulted in 11.3 t/ha (35.0%) higher than the standard variant, followed by the medium-fiber cultivar Bukhara-8 with 10.6 t/ha (33.7%).
