This study investigates the influence of mineral fertilizers on the growth and yield of sesame (Sesamum indicum L.) cultivated in the takir (saline and compacted clay) soils of the Surkhandarya region in Uzbekistan. The research aimed to determine optimal fertilizer compositions and application rates for improving soil fertility, plant growth, and oil yield in arid soil conditions. Field experiments were conducted using different combinations of nitrogen (N), phosphorus (P), and potassium (K) fertilizers. Results revealed that balanced fertilization significantly increased plant height, number of capsules per plant, and seed yield compared to the unfertilized control. The combined application of N90P60K60 provided the best results, enhancing yield by 28–32% over the control. The findings suggest that mineral fertilization plays a key role in increasing sesame productivity and improving the economic efficiency of agricultural production in arid zones of Uzbekistan.
