Soybean is a vital cash crop in the Jawi District, Northwest Ethiopia, and improving its productivity is crucial for food security and community socioeconomic status. Optimal phosphorus and deficit irrigation rates are still unresolved in this region. This study aims to optimize soybean productivity in the region by determining optimal phosphorus rates and deficit irrigation levels. The experiment was conducted during irrigation seasons of 2021/22 and 2022/23, using a split-plot design and RCBD arrangement. The results showed that combining P rates of 10, 20, 30, and 40 kg/ha P with 100% ETc significantly increased soybean grain production. Similarly, soybean grain yields increased with P rates of 0, 10, 20, 30, and 40 kg/ha P with 75% ETc. The highest water productivity recorded was 0.29 kg/m3 at 50% ETc. The study suggests that combining P rates of 10, 20, 30, and 40 kg/ha P with 100% ETc and P rates of 0, 10, 20, 30, and 40 kg/ha P with 75% ETc could significantly enhance soybean productivity. Implementing these strategies could lead to more sustainable and efficient agricultural practices in the Jawi District, improving crop yields and overall profitability.
