    Among the most important factors influencing plant nutrient uptake and water access are soil fraction and root architecture. However, little is known about how soil fraction x root architecture interaction affects woody plants. This study considered the differentiation of soil fertility parameters on layers through the root zone of two different soils and the quality and nutrient responses of three newly bred pomegranate varieties to soil fractions based on root architecture in clay and clay loam orchards. According to the findings, increasing clay content in the deeper layers has a negative impact on soil fertility, organic matter, phosphorus (P), and potassium (K). In clayey conditions, pomegranate varieties yielded lower in a range of 2.74% to 6.10% and significantly lower macro and micronutrient insertion. Conversely, the shallow-rooted variety accumulated significantly more boron (B) and P and set 50% more fruits in the clayey orchards. Soil fractions x root architecture significantly altered fruit quality characteristics, nutrient ingredients, and their relationships supported by a relatively low linear relationship in the Mantel test (r = 0.42). This study suggests that pomegranate tree responses to soil fractions are determined by root architecture. A proper approach to obtaining high-quality and nutritionally fortified pomegranates will incorporate appropriate cultivation techniques, such as suitable fertigation regime regulation, harvest date optimization, and soil organic matter enrichment, to provide uniform nutrient uptake based on the soil type and variety's root architecture.
