Water scarcity coupled with an increasing demand for water in agriculture has forced farmers to amend their irrigation practices and water management strategies. The proposed study was aimed at evaluating physiological and growth traits [photosynthesis rate, stomatal conductance (g S), chlorophyll content, leaf area, and fresh weight] under three irrigation levels (50%, 75%, and 100% of field capacity) in five varied textured soils (clay, clay loam, loam, sandy loam, and sandy). Response was evaluated on two baby spinach (Spinacia oleracea L.) cultivars (Dash and Hellios). Regarding physiological parameters, there were no interaction effects of deficit irrigation (DI) × soil texture. Significant increase on growth parameters (chlorophyll content, leaf weight, and leaf area) were observed under the interaction of 75% DI × sandy loam and loam soils on both ‘Dash’ and ‘Hellios’ during Season 1. ‘Hellios’ was able to adapt to deficit level of 75% during both growing seasons (summer and winter) under sandy loam soils. The study indicated that 25% water can be saved under sandy loam and loam soils when cultivating baby spinach during winter conditions.
