This study investigated the effect of bentonite clay application on the growth, development, and yield components of cotton (Gossypium hirsutum L.) under typical irrigated gray soils of the Navoi Experimental Station of PSUEAITI, Karmana district, Navoi region. The results showed that all bentonite-treated variants had higher plant height, number of fruiting branches, number of fruiting elements, number of bolls, and single boll weight compared to the control treatment. The highest values were recorded in the 11th treatment, where plant height reached 122.6 cm, number of bolls 15.6, open bolls 12.4, and single boll weight 4.5 g.
