Nutrient deficiencies, low organic matter content, and a limited soil–water saturation percentage in calcareous soils hinder plant growth crop production. To address these challenges, sustainable green-based farming practices have been introduced. This study investigates the synergistic effects of biochar nitrogen levels as solutions for improving soil fertility supporting wheat soils. A pot experiment assessed (5-, 10-, 15-tons ha−1) (60, 90, 120 kg on physicochemical properties, nutrient availability, growth. The randomized complete block design included three replicates control. results highlight that highest rate (15 tons combined with level (120 significantly (p ≤ 0.05) improved properties status. Notably, pH increased by 2.8%, electrical conductivity 29.8%, 185%, while bulk density decreased 22.3%. Soil total surged 163.7%, 27.2%, plant-available phosphorus 66.8%, potassium 96.8%. Wheat parameters also showed marked improvement, height up 29.7%, spike length 20.7%, grains per 41.5%, thousand-grain weight 24.7%, grain yield 81.3%, biological 26.5%. There was strong positive correlation between enhanced growth, except density, which negative correlation. underscores role boosting productivity. principal component analysis further validated findings, suggesting integrating appropriate fertilization offers strategy to enhance health, manage strengthen yields soil. Biochar application elevated enhances productivity semi-arid regions, offering solution Future studies should explore long-term impacts scalability this approach.
