Dr. Abdullah Mohammed Ahmed Obadi is a distinguished researcher at King Saud University, specializing in Vegetable Crops and Horticultural Sciences with a focus on biochar applications, soil and water management, and sustainable vegetable production under stress conditions. Holding a Ph.D. in Vegetable Crops (Horticulture) from King Saud University with first-class honors, his doctoral research titled “Effect of biochar application on growth, yield and quality of tomato crop under stresses salinity and drought” has significantly advanced the understanding of biochar’s role in improving soil productivity and plant resilience. His master’s research, “Effect of Biochar and Compost on the Growth and Production of Bell Pepper under Different Irrigation Water Levels,” further established his expertise in soil amendments and irrigation management for enhanced crop performance. Dr. Obadi’s scientific contributions encompass diverse areas, including hydroponic vegetable production, plant physiology, environmental stress tolerance, and soil health improvement. He has co-authored several impactful publications such as Effectiveness of Grafting in Enhancing Salinity Tolerance of Tomato Using Novel and Commercial Rootstocks in Soilless Systems, Enhancement in Tomato Yield and Quality Using Biochar Amendments in Greenhouse under Salinity and Drought Stress, Improving Water Productivity in Greenhouse and Open-Field Vegetable Crops, The Use of Biochar Can Improve the Hydro-Physical Properties of Sandy Soils in Arid Regions, and Effect of Biochar Application on Morpho-Physiological Traits, Yield, and Water Use Efficiency of Tomato Crop Under Water Quality and Deficit. His works also explore Biochar and Compost as Soil Amendments Affecting Sweet Pepper Growth under Partial Root Zone Drying Irrigation and Tomato Grafting Impacts on Yield and Fruit Quality under Water Stress Conditions. Through his research, Dr. Obadi has made remarkable contributions toward sustainable agriculture, efficient water use, and environmental rehabilitation, combining scientific innovation with practical agricultural applications to support food security in arid and semi-arid regions.
