Abstract: A field experiment was conducted to study the effect of fertigation on the qualitative parameters of tomato (<em>Solanum lycopersicum </em>L.). The experiment was laid out with five replications and six treatments along with control in naturally ventilated Polyhouse with combinations of different doses of nitrogen, phosphorous and potassium. The different fertigation levels 100% RDF, 90% RDF, 80% RDF, 70% RDF and 60% RDF were tested during the course of experiment. Ascorbic acid (32.67 mg), Titratable acidity 0.47 (%) and TSS (5.10 ⁰Brix) were increased with the application of 100% RDF. The maximum nitrogen content (199.97 kg), phosphorus content (24.78 kg) and potassium content (140.84 kg) were recorded in application of 100% RDF.
