The present investigation on effect of P and K levels on yield and quality of spinach was carried out during Rabi season 2012-13 at College Garden, Department of Horticulture, College of Agriculture, Nagpur.The treatments were three levels of phosphorus viz., 0 kg (P0), 10 kg (P,1), 20 kg (P2) and potassiumviz., 0 kg (K0), 15 kg (K1), 30 kg (K2).The experiment was laid out in FRBD with three replications. The experimental soil was slightly calcareous, alkaline in reaction and clayey in texture. It was sufficient in potassium and low in organic carbon, available nitrogen and phosphorus. Among the quality parameters, the maximum leaf area (112.03 cm2 and 111.84 cm2), protein (10.97% and 11.21%), chlorophyll (1.93 and 1.98 mg g-1), and ascorbic acid content (71.48 mg and 71.54 mg) were found in treatment which received phosphorus @ 20 kg ha-1 and potassium @ 30 kg ha-1, respectively at harvesting.
