During the two winter seasons of 2020-21 and 2021-22, the research was carried out on the Nile Delta., Egypt, clayey soil to assess the use of a modern drip irrigation system and foliar spraying with some biostimulants, with an emphasis on yield traits, relative water saved, storability of garlic for (Allium sativum L.), and economic evaluations. The findings indicated that the drip irrigation system and foliar spray biostimulants exhausted a significant improvement in all garlic traits compared with the control. Foliar spraying with yeast at 2 g l -1 gave the highest values for plant height, leaf number per plant, leaf area, bulb diameter, bulb fresh weight, total yield, total sugar, total flavonoids, total phenols, K%, Na% and K/Na ratio traits for the two garlic growing seasons. In addition, Ascorbic acid application (0.2 gl-1 ) and yeast (2 g l-1 ) achieved the lowest weight loss (%) of stored garlic bulbs during the storage period. Regarding the relative water saved and economic water productivity, drip irrigation and biostimulants, in particular, yeast extract or compost tea, may have higher initial costs, but they can also result in higher yields and water savings, which can provide greater economic advantages.
