Date palm is a vital fruit crop widely cultivated in developing regions, contributing significantly to food security, nutrition, and economic sustainability due to its rich content of carbohydrates, minerals, dietary fiber, and bioactive compounds. This study evaluated the combined effects of vermicompost (VC) and micronutrients with amino acids (Trace-amino, TA) on the yield and fruit quality of Barhi date palm under the agro-climatic conditions of Qena Governorate, Southern Egypt. Seven treatments were applied, including three levels of VC (50, 75, and 100 mL L⁻¹) as a soil application combined with two foliar levels of TA (2 and 4 g L⁻¹), in addition to a control treatment (water spray). The results showed that all treatments significantly improved yield components, including fruit set, fruit retention, bunch weight, and yield per palm, as well as fruit physical and chemical characteristics compared to the control. The highest yield and best fruit quality were recorded with the application of VC at 100 mL L⁻¹ combined with TA at 4 g L⁻¹, followed by VC at 100 mL L⁻¹ with TA at 2 g L⁻¹ during both seasons.
