The study conducted at the experimental farm of the Research Institute of Selection. Seed Production, and Agrotechnology of Cotton (Bukhara Scientific Experimental Station) examined the effects of Chlorella vulgaris suspension on the Bukhara-10 cotton variety under extreme Bukhara conditions ("Afghan heat." saline, and desert-arid zones). Among four tested methods, the fourth option, which involved a combined application of Chlorella vulgaris suspension, showed the best results. This treatment increased the number of cotton bolls by 4 pes per bush, capsule weight by 1.0 g. and yield by 12 c/lia compared to the control. The soil pH decreased from S.l to 7.5, indicating improved soil conditions. The positive effect of Chlorella vulgaris is attributed to its rich composition of phosphorus, nitrogen, calcium, potassium, iron. zinc, and over 40 amino acids, which enhance nutrient absorption and balance soil salinity. As a result, plant growth improved through better nutrient distribution, photosynthetic activity, and accumulation of dry matter. The treatment increased photosynthetic surface area to 55.2 thousand m2/ha, dry mass to 275 g/bush, boll number to 16 pes/bush. and photosynthesis productivity to 10.9 g/m2/day. which was 20.8 thousand m:/ha higher than the control.
