Abstract

Sunflower (Helianthus annuus L.) is an important oilseed crop widely cultivated under diverse environmental conditions. However, water deficiency and soil salinity are among the most critical abiotic stresses limiting productivity. This study evaluates the bio-eco-physiological responses of seven sunflower varieties (Dilbar, Diyor, VNIIMK-888, Jahongir, Sur, Navro’z, and Alomat) under field conditions. Morphological parameters, growth dynamics, and yield-related traits such as plant height, leaf number, leaf dimensions, stem thickness, and 1000-seed weight were analyzed. Results showed significant varietal differences in stress tolerance, with Diyor demonstrating superior adaptability and productivity. The findings highlight the importance of varietal selection in stress-prone environments and provide insights for sustainable sunflower cultivation under water and salinity stress conditions.
