| Abstract | ||
| The field experiment was conducted on garlic (Allium sativum L.) cultivar seds 50 during winter seasons 2022/2023 and 2023/2024 growing seasons on a private farm located in Shanasha village, Aga District, Dakahlia Governorate, Egypt. A field experiment was designed in randomiz complete block design to assess the impact of varying potassium fertilization levels (50%, 75% and 100% of the recommended dose KRD as K2SO4) combined with bio-fertilization using potassium-solubilizing bacteria (KSB). Additionally, a control treatment of 100% of KRD without PSB was included. These treatments were applied to evaluate their effects on garlic growth and yield. Results showed that applying 75% of KRD with KSB significantly enhanced plant growth indicators, such as plant height, and fresh and dry weights compared to other combined treatments. This combination also led to higher nutrient concentrations (N, P, K, B) in leaves and SPAD chlorophyll readings compared to other combined treatments. At harvest, the same combined treatment achieved the highest values for yield components and bulb quality traits such as vitamin C and dry matter. In contrast, using only 50% of KRD resulted in the lowest growth and yield outcomes, emphasizing the necessity of adequate potassium supplementation. Overall, the study demonstrates that using 75% KRD combined with PSB is an effective, sustainable approach to boost garlic yield and quality while reducing environmental impact | ||
