A field experiment conducted during Rabi 2024-25 at the Research Farm, College of Agriculture, Karad, evaluated the effect of foliar application of potassium fulvate, Fe, and Zn on the yield and quality of spinach (Spinacia oleracea L.) under Inceptisol conditions. Among nine treatments tested in a randomized block design, GRDF + potassium fulvate 0.4% + FeSO₄ 0.5% + ZnSO₄ 0.5% recorded the highest green leaf yield (200.46 q ha⁻¹), plant height, number of leaves, leaf area, ascorbic acid, chlorophyll and protein content. This treatment also produced superior quality, with maximum ascorbic acid (33.73 mg 100 g⁻¹) and protein content (23.10%), owing to improved nutrient absorption, chlorophyll synthesis and metabolic activity, making it an effective strategy for enhancing spinach yield and quality under Inceptisol conditions.
