Abstract

  The field experiment was conducted on garlic (Allium sativum L.) cultivar seds 50 during 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 Mono Ammonium Phosphate (MAP) at 250 ppm, Copper Gluconate (C12H22CuO14) at 250 ppm, Calcium/Boron Mix (Ca/B) 250 ppm, Potassium Silicate (K2O3Si)250ppm and Control (without foliar application) spraying water only, to evaluate their effects on garlic growth and yield.  Results showed that applying, Potassium Silicate (K2O3Si) 250 ppm significantly enhanced plant growth indicators, such as plant height, 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, pungency and dry matter. In contrast, control (without spraying) resulted in the lowest growth and yield outcomes,
