Abstract
Currently, there is growing interest in improving the use of organic fertilizers, especially in their liquid forms, which offer a promising alternative to traditional fertilizers. Therefore, this research work aimed to assess the influence of liquid organic fertilizers (compost tea, vermicompost extract, and biogas digestate) at different levels (0.0, 1.5, 3.0, 4.5, and 6.0 m3 fed-1) on garlic plant performance and soil properties. biogas digestate application resulted in the highest values of garlic yield components and quality such as average bulb weight (g), bulb diameter (cm), neck diameter (cm), total bulb yield (ton fed-1), carbohydrate content (%), total dissolved solids (TDS, %), vitamin C content (mg 100 g-1), followed by vermicompost extract, while compost tea showed the lowest values. Noting that, increasing the application level of each fertilizer consistently improved all traits, with the highest values recorded at 6.0 m3 fed-1 under each fertilizer, compared to the lowest levels. Generally, the superior treatment was biogas digestate at a level of 6.0 m3 fed-1. Also, among the studied organic fertilizers, biogas digestate led to the highest improvements in soil traits like NPK (mg kg-1), OM (%) and CEC (cmol kg-1), followed by vermicompost extract then compost tea. Therefore, it can be recommended to integrate biogas digestate into fertilization programs.
