Abstract: Radish is one of the important root vegetables cultivated in India for its tender roots which are used as salad or cooked vegetable. Soil was collected from Vallampadugai, Chidambaram taluk farmer’s field having sandy loam soil texture, pH 7, EC 1.37 dSm^-1, (<em>Typic ustifluvents</em>). Pot experiment was conducted in Department of Soil Science and Agricultural Chemistry, Annamalai University to evaluate the root yield of radish. The treatments were T₁ – Control 100% RDF, T₂ – 100% RDF + Municipal Solid Waste Compost @ 5 t ha^-1, T₃ – 100% RDF + Municipal Solid Waste Compost @ 10 t ha^-1, T₄ – 100% RDF + Farmyard manure @ 12.5 t ha^-1, T₅ – 100% RDF + Farmyard manure @ 25 t ha^-1, T₆ – 100% RDF + Rice husk ash @ 5 t ha^-1, T₇ – 100% RDF + Rice husk ash @ 5 t ha^-1, T₈ – 100% RDF + Bagasse ash @ 5 t ha^-1, T₉ – 100% RDF + Bagasse ash @ 10 t ha^-1. There were nine treatment combination replicated thrice in CRD. The result showed that yield attributes <em>viz., </em>root length (19.4 cm), single root weight (281.9 g plant^-1) and shoot yield (501.9 g plant^-1). The maximum root yield pot^-1 (845.9 g pot^-1) was recorded in treatment receiving 100% RDF + FYM @ 12.5 t ha^-1 (T₅).
